Introduction
Welcome to the OSIX System Description. This document aims to provide
a brief description of the purpose and use of the OSIX product.
1.1
The OSIX advantage
OSIX extracts information from the control and user plane, independently from the
switches, in true real-time. Regardless of the size of the network, number of links
and sites, or the type of distribution used, OSIX will provide an optimised solution.
OSIX is a distributed and robust system, which has been designed with high
scalability and flexibility in order to quickly adapt to new demands and
requirements, enabling the system to serve the customers over a long period of
time.
OSIX has integrated solutions for various domains, from legacy SS7 to LTE,
advanced alarm functionality, location tracking, handset tracking, customer/service/
network statistics, SMS messaging, security detection, roaming management, etc.
The OSIX Main Panel includes a set of applications that are used to monitor,
troubleshoot, view and analyse the network data, as well as to generate xDRs (data
records) and SNMP traps.

Business value
In today’s market environment, it is absolutely essential for operators to understand
what their customers are using the network for and how they experience it.
Smartphones and data usage have increased subscribers’ demand for bandwidth
and their expectations of service and performance.
In order to maintain a first-class customer experience, advanced real time
surveillance and troubleshooting capabilities are crucial to any organisation
operating networks.
The OSIX system provides tools to:
Monitor network performance and Quality of Service (QoS).
Generate real-time alarms on abnormal network behaviour.
Detect poor network performance and prevent customer-affecting service
issues by providing fast and accurate error finding.
Resolve network problems faster through an intuitive display of information.
Gain access to all signalling data across any network technology for the
network-wide troubleshooting and root-cause analysis in real-time or
historically.
View and analyse end-to-end QoS and correlate information from different
sources on a multi-protocol level.
Perform detailed root-cause analysis on call, session and protocol levels using
unique drill-down capabilities.
Retrieve historical control signalling and user plane data for analysis purposes.
Generate xDRs for northbound integration.
Provide SNMP alarm generation to other systems.
1.3
Business solutions
Different departments of an organisation have different needs, and Polystar’s
business solution portfolio has been designed with that in mind. The solutions have
been grouped under two conceptual headings, Network Insight and Customer
Insight, and for these OSIX is an integral part:
1.3.1 Network insight
Network and service performance is measured by various performance indicators
and can be applied to any specific measurement or network event. Real-time alarm
generation on service degradation facilitates proactive and rapid problem
resolution. The network and service indicators can be displayed on a fully
customisable dashboard, with drill-down capabilities for further analysis.
Polystar’s roaming solutions rely upon our network probes to ensure all information
relating to all roamers and their activity is seen. Whether the question is to find
where in the network inbound roamers are lost and gained, or generating GRQ
reports, Polystar provides real-time visibility of all roaming activity inside and
outside the network.

Introduction
1.3.2 Customer insight
Keeping the customer satisfied is key to long-term retention and subscriber loyalty.
Polystar’s Customer assurance solution provides operators with complete end-toend visibility of services (voice, SMS, video, data session, etc.) as experienced by
individual subscribers, subscriber groups and VIP accounts. Customisable
dashboards provide real-time information to company management, marketing,
customer care and sales departments about customer experiences on key revenuegenerating services.

System overview
This chapter describes the OSIX system design, with sections on the
system architecture.
2.1
Overview
The OSIX system consists of probes, servers, and clients. The probes are nonintrusively connected to the links in the signalling network, and are independent
from data collected by the switches.
The signalling traffic gathered by the probes is forwarded to the different servers,
which process and deliver the data to various applications and reporting tools.

The data can also be stored in the OSIX SOS (Storage of Signals) database, or in
storage subsystems for analysis of historical data. For even older data, the Call
Search Engine can be used for displaying transaction entry summaries for
transactions that are no longer stored in full in SOS.

Figure 3: Typical OSIX architecture
2.2.1 Probe
2.2.1.1
Network interface hardware
The different types of signalling links are non-intrusively accessed via the network
interface hardware. See 5.1 Hardware for detailed information.
2.2.2 Router
2.2.2.1
Distribution/Load sharing
The Router collects messages from all the connected probes and will distribute
them evenly on to the probe servers. All messages belonging to a certain call/
process will be sent to the same probe server. This is done through a fast algorithm
that is different for every protocol.
2.2.3 Probe server
2.2.3.1
Collection
Collects and correlates all the protocol messages from the data streams received
from the network interface hardware, or router. Correlation is done between
messages from the entire network, and between certain protocols and transaction
parts, as well.
System Description
OSIX 5.6
5
System overview
2.2.3.2
Decode
The different protocol messages are decoded, and interpreted, before they are
forwarded to the state machine.
2.2.3.3
Decipher
Ciphered messages on the Gb and S1-MME interfaces are deciphered in real time
by the Probe server. For this purpose, ciphering keys are fetched from the Mapping
server. It is vital that the Mapping server is up-to-date at all times, which means that
the Gb, Gr, Gn, S1-MME, S6a and S11 interfaces have to be monitored and
processed in real time. Normally, the Probe server can decipher over 90% of the
signalling for Gb.
2.2.3.4
State machine
The state machine initiates one unique process for each individual transaction,
keeping track of the states of the transactions. Required data is then sent either to
the OSIX applications (either directly, or via the Performance server, or historically),
or the xDR generator.
2.2.3.5
xDR generator
With the xDR generator functionality you can produce customer-defined xDRs, in
different formats, in true real time. The xDR generators, which will generate xDRs
based on any filter settings you may wish to have, and in the format of your choice,
send the xDRs to the assigned IP address and port. You can have several xDR
generators generating different types of xDRs active at the same time, and partial
xDRs are also available.
2.2.3.6
SOS - Storage Of Signals
The SOS database stores data for historical analysis in the Call Trace and Protocol
Analyser applications. SOS allows instant access to all signalling data. For older
data, the Call Search Engine (CSE) or the Message Search Engine (MSE) can be
used for displaying calls/messages that are no longer stored in full in SOS.
2.2.4 Mapping server
Every Probe server has a connection towards the Mapping server. Whenever a new
IMSI-TMSI (P-TMSI) pair is discovered in the signalling, the Mapping server is
informed (when a TMSI reallocation is performed the Mapping server is also
updated). When a call/transaction with only TMSI (P-TMSI) is handled by a Probe
server, the Mapping server will be queried for the correct IMSI for the corresponding
TMSI (P-TMSI). The Mapping server will also keep keys used for deciphering, for
example for Gb traffic.
2.2.5 Application specific servers
2.2.5.1
Performance server
The Performance server is the engine behind the OSIX applications Mass Call and
Performance Analyser, as it feeds both of these applications with necessary data.
See 3.2.4 Mass Call, or 3.2.3 Performance Analyser, for further information.
2.2.5.2
OSS server
The OSS server processes the information from the probe servers for use with the
different OSS applications.
System Description
OSIX 5.6
6
System overview
2.2.6 Client applications
The client applications are used by the end users to monitor, analyse, troubleshoot,
or otherwise use the data from the signalling network.
2.2.6.1
OSIX applications
The OSIX applications are integrated with the system as well as with each other,
and currently include:
Call Trace, for monitoring transactions in different protocols, where all
messages related to each process are grouped together, either in real time or
historically, networkwide,
Protocol Analyser, for monitoring and troubleshooting protocol messages for all
supported protocols, either in real time or historically,
Performance Analyser, for monitoring of different KPIs (Key Performance
Indicators), in real time, such as ASR, NER, PDP Activations, successful
transactions, transaction frequency, response times, successful SMS
transactions, etc. The data is presented in real time, alarms are generated
when the performance goes beyond the set alarm threshold, and the
application includes instant access to Call Trace and Protocol Analyser,
Network Status, for monitoring network related alarms on MTP1 level, MTP2
level, MTP3 level, or alarms for high link loads, poor performance, high
amounts of call attempts, or alarms triggered by certain types of messages or
transactions, with quick access to Call Trace and Protocol Analyser,
Mass Call (PSTN only), for detecting calls that are looping around, and early
stages of congestion, etc., when monitoring mass calls for B numbers, and for
detecting fraudulent calling patterns, etc., when monitoring calls for A numbers,
with instant access to Call Trace and Protocol Analyser,
Real Time Statistics, for setting up diagrams with different graphs displaying the
number of protocol messages or transactions that are passing the filter settings
applied, in real time.
Statistics Alarm, for setting up alarms to be generated when certain filter
criteria for protocol messages or calls/transactions are met.
Packet Recorder, to record packet streams of user plane data, typically on the
Gn, Gp, S1, S8, Gi, and SGi interfaces.
See 3.2 OSIX applications for further general information.
All OSIX applications are available à la carte to help you build your OSIX system
with just the right combination of applications you need to meet your specific
network monitoring requirements.
2.2.6.2
Third-party systems
Third-party systems, such as Revenue Assurance systems, Billing systems, Fraud
Management systems, and Quality of Service systems, can all have their own
customised xDRs generated by the different xDR generators. Other systems such
as Network Management systems, can receive information in the form of SNMP
traps. See 3.3 xDR generator, and 3.5 Alarm specification, for further information.
System Description
OSIX 5.6

System overview
2.2.6.3
Sirius
Sirius contains Polystar’s special applications. The following applications are
available:
SMS welcome (formerly sGate)
Sends messages to subscribers welcoming them to a network in a new country.
Handset identifier (formerly Handset tracker)
The Handset identifier is a tool that keeps track of which physical handset a
client is currently using.
See the respective system description for further information about the Sirius
applications.
2.2.6.4
Jupiter
Jupiter gives the user access to all possible perspectives, from a helicopter view to
unmatched drill-down possibilities for in-depth network investigation. Jupiter’s
graphical interface encourages a proactive use that inspires new ways to monitor
the data to find degrading trends and other anomalies. Potential problems can be
dealt with before they affect the quality of service, increasing the competitiveness of
the network operator’s business. See the Jupiter System Description for further
information about Jupiter.
2.3
Multiple Network Support
Support for multiple networks means the ability to operate on two logical/ physical
separated networks in a customer network.
Network separation is done between the user application layer (OSIX client) and the
server side (backbone), by usage of physical separated network ports on the GLS,
PRS and Jupiter Web server as illustrated below.
Figure 4: Network separation illustration
Monitored traffic is processed in the backbone network and client requested traffic
is provided in the user network.
System Description
OSIX 5.6

System overview
In addition to already mandatory IPs in the backbone network, additional IPs for the
user network is required for this purpose, i.e. one IP address per JVM component
per network inherence
Support for multiple network is charged separately and a separate licence is
required enabling this feature.

The data can be sent to the OSIX applications, which display protocol
messages, calls/ transactions, performance, mass call attempts, diagrams over
real time traffic, and alarms on MTP1, MTP2, and MTP3 levels, as well as on
link load.
The data can be sent to the SOS (Storage of Signals) database for later
retrieval of protocol messages and/or calls/transactions. For older data, the Call
Search Engine can be used for displaying transaction entries that are no longer
stored in full in SOS.
The data can be sent to the OSIX xDR generator, which generates customised
xDRs. These xDRs can be used for Billing Verification, Revenue Assurance,
Fraud Management, Device Management, Service Assurance, and other third
party systems. Several different xDR generators for different formats, and for
different systems can be configured.
Different events can trigger SNMP traps, which are sent to external Network
Management applications.
The data can be sent to the OSS applications.

OSIX applications
Currently, seven different OSIX applications can be included in the OSIX system:
Protocol Analyser, Call Trace, Performance Analyser, Mass Call, Real Time
Statistics, Network Status, Statistics Alarm, and Packet Recorder. (For information
about the Configuration Manager and the System Status application see
7.1 Configuration Manager and 7.2 System Status.)
3.2.1 Protocol Analyser
The Protocol Analyser application monitors protocol messages, in real time or
historically with SOS. Included in the application are advanced filtering
functionalities, and comprehensive tools for adapting the user interface. You also
have quick access to detailed information within the protocol messages down to
each individual bit and byte of the signalling.
This application will help you solve network problems at a deeper level, and find
reasons for erroneous transactions, by filtering on specific protocol messages, etc.

3.2.1.2
Filters
There are six different type of filters:
Traffic Groups - The links in your network are divided into one or more traffic
groups, and you must select at least one traffic group before you can start
monitoring messages. (Protocol Analyser and Call Trace.)
Historical/RT - You can switch between historical and real time search mode.
The historical filter is used for viewing calling processes historically, that is from
a certain time interval, and with a certain duration. A historical search will filter
out all messages that do not fit in the time period selected in the search filter.
(Protocol Analyser and Call Trace.)
Parameters - You may set a filter on any parameter value visible in the Main
Window. The quickest way to do this is to right-click the value and add to filter.
This filter type also allows you to exclude messages with specific values.
(Protocol Analyser and Call Trace).
Links - You can select to only view messages being sent on one or more
specific links. (Protocol Analyser and Call Trace.)
Protocols - If you are running more than one protocol, you can easily select to
only view messages of a certain protocol type. (Protocol Analyser and Call
Trace.)
System Description
OSIX 5.6
13
Applications overview
3.2.1.2.1 Server filter - View filter
The parameter, link, and protocol filters can be set both as a server filter and as a
view filter. A server filter determines which messages should be sent from the probe
servers to the client computers, minimising the load on the LAN/WAN, while the
view filter searches through the messages sent to the client computer and displays
messages passing the filter criteria, and can thus be turned on or off.
3.2.1.2.2 Combining filter criteria
Filters can be set to display either messages where a certain parameter equals a
certain value, or messages where a certain parameter does NOT equal a certain
value. The set filter criteria can then be combined with AND/OR functionality.
3.2.1.3
Available parameters
For available protocol parameters for Protocol Analyser, see 12.3 Protocol
Analyser.
3.2.2 Call Trace
The Call Trace application monitors calling processes, in real time or historically
with SOS, or CSE/MSE. Included in the application are advanced filtering
functionalities, and comprehensive tools for adapting the user interface. You also
have quick access to detailed information about the processes, and all the
messages sent during the processes.
The comprehensive correlation functionality allows you to view messages, end-toend, for all the different transactions that are parts of the logical transactions, such
as all the transactions relevant for a mobile call, or an SMS transaction, or a VoIP
call, for example.
The call flow view, displaying how the messages are sent between different nodes,
is available for both single transactions and correlated transactions.
This application will help the customer support staff to give top class service to your
subscribers with a complete overview of all the calling processes. You will also be
able to find reasons for poor statistical values detected in Performance Analyser, or
see if there were any disturbances during an alarm in Network Status, etc.
Signalling technicians will have access to all the bits and bytes in every calling
process and protocol message for deep analysis as well.

3.2.3 Performance Analyser
The Performance Analyser application monitors Key Performance Indicators for
different transaction groups in real time, which will show you the performance in
your network.
For each KPI alarm thresholds can be set per transaction group.
The following pre-defined protocol-specific KPIs are available:
ASR (Answer Seizure Ratio) - displays the number of successful call attempts
(answered or terminated with a normal release cause) out of the total number
of call attempts in per cent. Alarms are generated when the current levels go
below the set alarm thresholds. (For ISUP, IUP, BICC, ISDN, SIP, and Iu-CS.)
NER (Network Efficiency Ratio) - displays the number of calls terminated with
a normal release cause, user busy, or no answer, out of the total number of call

thresholds. (For GTP.)
Response Delay - displays the delay between a request and a response, for
example between a Create PDP request and a Create PDP response, in per
cent and in milliseconds. The control signalling affects the value, not the user
data. Alarms are generated when the current levels go above the set levels.(For
GTP.)
User Data Throughput - displays the min/max throughput downlink (for
example when a user is browsing a web page), in per cent and in milliseconds,
and uplink (for example when a user is sharing a file), in per cent and in
milliseconds. (For GTP.)
The transaction groups can consist of many different parameters, enabling you to
pin-point and monitor statistics for an exact type of transaction, originating at certain
places, terminating at certain places, containing specific numbers, etc.
Performance Analyser will help you increase your quality of service, since you can
instantly see in which areas the performance is going down. This information allows
you to reroute the calls, without affecting the customers, while solving the problem.
You also have instant access to the Call Trace and Protocol Analyser applications
where filters are automatically set on the parameters the selected group is based
on. You can then see if and how the traffic was affected by the alarms.
Figure 11: Performance Analyser Main Window
This application will help you detect problems quickly, and decrease the time
required for problem solving. The application is typically displayed on in the NOC
wall. Alarms can be sent to an internal alarm application of to third-party alarm
management systems using SNMP traps.

Applications overview
3.2.4 Mass Call
In the Mass Call application (PSTN only) you can monitor either the number of call
attempts made to specific numbers, or made by specific numbers. ISUP, IUP and
BICC protocols are supported.
3.2.4.1
Mass Call B Number
Monitoring call attempts to specific numbers will help you see if you need to reroute
the traffic, or activate call gapping. For example, when there are massive amounts
of call attempts for a TV vote, or to a booking centre for newly released theatre
tickets, etc. You will also be able to find errors in routing tables which results in calls
that are looping around the network.
Figure 12: Mass Call B Number
3.2.4.2
Mass Call A Number
Monitoring call attempts made by specific numbers will help you find subscribers
that have strange calling patterns. For example, if a dialler has been connected to
automatically find free extensions in a corporate switchboard.

3.2.4.3
Common features
You have instant access to the Call Trace and Protocol Analyser applications where
filters are automatically set on selected numbers and/or second numbers/PC NI
combinations. You can then see if and how the traffic was affected by the alarms.
This application helps you solve problems before customers are affected by
overloaded switches, and stop fraudulent subscriber behaviour. See 8.6 Mass Call,
in the chapter 8 OSIX for PSTN networks for further information.
3.2.4.4
Specific alarm levels
If there are specific numbers, or number sequences, that frequently have large
amounts of call attempts, specific alarm levels can be applied, which will reduce the
number of alarms for these numbers, or number sequences.
3.2.5 Real Time Statistics
With the Real Time Statistics application you can set up and view diagrams, or
statistical information in table format, over certain types of messages and/or calls in
your network in real time. This allows you to immediately detect drops or peaks in
the traffic, which need further attention.
Different filter criteria can be set up for the different graphs, based on either protocol
messages or calls. Several graphs can also be combined in the same diagram,
where each graph has its own designated colour for easier identification.
When setting up the diagrams, you select if you wish the graph to be based on
messages or calls, and then you can apply different filter settings:
Traffic group filter – messages/calls passing the links in the selected traffic
group(s) will be counted
Protocol filter – messages/calls for the selected protocol(s) will be counted
Link filter – messages/calls for the selected link(s) will be counted
Parameter filters – messages/calls matching the set parameter values
(settings for wildcards, ranges, non-existent parameters, etc., can be used) will
be counted
System Description
OSIX 5.6
20
Applications overview
You can also select to open filters that you have saved in the Protocol Analyser or
Call Trace applications and re-use them in the Real Time Statistics application,
which also means that all the parameters available for filtering in Protocol Analyser
and Call Trace, are also available for filtering in Real Time Statistics.
Once the filters are set, and you select to view the diagram, the graphs will display
the number of messages/calls passing the filter settings in real time. The graphs are
updated with the time resolution of your choice.
All the filter settings can also be saved and used at a later time, or shared between
colleagues.

3.2.6 Network Status
The Network Status application monitors alarms on MTP1 level, MTP2 level, MTP3
level, and on high link load, poor performance, large amounts of call attempts, and
alarms generated by certain types of messages or transactions, and displays them
in a user interface, which allows you to acknowledge and clear the alarms, as well
as search for similar alarms throughout your network.
You also have quick access to the Call Trace and Protocol Analyser applications,
where you can then see if your subscribers were affected in any way by the alarms.
Figure 16: Network Status Surveyor view
This application will help you detect problems quickly, and decrease the times for
problem solving.
3.2.7 Statistics Alarm
In the Statistics item you can set up different filter criteria, which will generate
alarms if they are met. For example, you can set up a filter on B Number equals 555
55 55. As soon as a protocol message, or call, with B Number 555 55 55 is
detected, an alarm is generated. You can also set filters to generate alarms when
you have calls with a certain duration, or if you have more than 500 IAM messages
per minute, etc. All the filter options included in the Protocol Analyser and Call Trace
applications are available.

3.2.8 Packet Recorder
The purpose of Packet Recorder is to record packet streams of user plane data,
typically on the Gn, Gp, S1, S8, Gi, and SGi interfaces. The Packet Recorder
application is run in a web GUI that supports Firefox, Internet Explorer and Google
Chrome.
Packet streams are stored locally on a MediaProbe based on a capture filter defined
by the user. Streams may be set to capture a fixed volume of data (e.g. 10MB) or as
sliding window storage where the oldest data is continuously replaced by newer
data.
Stored data may be accessed in multiple ways, including export in a PCAP format
for offline processing or decoding in Wireshark. Data can be searched for specific
signalling or exported in its entirety. GTP-U data and Gi/SGi user plane data may
also be loaded into Call Trace and displayed together with the corresponding GTPC session.
Figure 18: Packet Recorder Main Window
System Description
OSIX 5.6
23
Applications overview
The application is available in two versions:
Packet Recorder – Light
The light version supports recording of GTP-U data based on an IMSI filter.
Packet Recorder - Full
The full version of the application includes additional GTP capture filters, such
as node IP, tunnelled IP, tunnelled port, vlan and using no filter at all. It also
includes filters for Gi/SGi or other IP-based interfaces including vlan, IP and port.
This version of the application requires additional hardware compared to a
normal MediaProbe, which does not have the necessary disk space to support
all filter options.
3.3
xDR generator
With OSIX you can receive partial xDRs in true real-time to, for example, your Fraud
Management System. This means that you can detect fraud even prior to
connection, and you are not limited to the static and restricted xDRs from the NEs
(Network Elements).
The xDRs delivered by the switches are also often incomplete, for example during
peak traffic times, which means you lose billing data. The OSIX system always
deliver 100% of the xDRs in whichever formats and states you desire.
In the system you can configure several different xDR generators, with different
formats, with different filters (that is, you can decide to generate xDRs when certain
filter criteria are met), and send them to different ports on different IP addresses.
Figure 19: xDR Generator example
System Description
OSIX 5.6

Applications overview
3.3.1 Interfaces
The xDR-generation has three main interfaces towards third-party systems; pure
socket (real-time), file server (near real-time), and database (near real-time).

3.3.1.1
Pure socket
xDRs are sent in a binary stream according to the specified xDR format. The thirdparty system must be able to read data from the socket at the same speed as OSIX
sends data. If the third-party system is too slow, or disconnects, a backup
functionality is activated.
3.3.1.2
File server
With the file server interface, OSIX uses a disk saver application that saves xDRs to
disk according to the specified format. xDRs are stored in sequence, and there is no
extra header inserted between the xDRs.
3.3.1.3
Database
If required, a database can also be used as the interface to third-party systems for
some of the protocols supported. This option requires a Jupiter installation.
3.3.2 Formats
The xDRs can be delivered in several different formats, and for several different
purposes and protocols - simultaneously.
3.4
SOS (Storage of Signals)
With SOS functionality you will be able to view calling transactions and protocol
messages historically.
Each probe server has a SOS database which stores all the signalling data. The
storage time can be configured per probe server and protocol, making it possible to
store, for example, SIP for a longer time period than Megaco.
When the clients select a time interval to view calling transactions or protocol
messages from, the data is sent from the SOS database(s) to the clients, and will
be displayed in the Call Trace and Protocol Analyser applications. For older data,
the Call Search Engine (CSE) and the Message Search Engine (MSE) can be used
for displaying transaction entries, with limited information, that are no longer stored
in SOS. See 13 SOS columns, for available parameters that are supported for CSE.
The transactions and messages will be displayed in the same way as when you are
running the applications in real time, with the same filtering functionality, quick
access to details, etc. The number of days you store data in SOS is freely
configurable. You just have to have enough servers to handle the amount of data.

This chapter describes different OSIX system configurations.
4.1
Overview
The configuration of the OSIX system can either be distributed or centralised,
depending on your network. In case you have a large amount of links which need to
be grouped together, and correlated, a router configuration may also be considered.
4.2
Distributed configuration
The common configuration is a distributed configuration where there are probes
non-intrusively connected to the links at each site.

Router configuration
For larger installations, a router configuration can be applied in order to take
advantage of the full capacity in the probe servers, and share processing load
between the servers. The traffic is then gathered by the probes, sent to the router,
and then evenly distributed between the probe servers.
In very large installations, several routers can be configured to work as one large
router as well.

Two systems in one GUI
OSIX offers the possibility to visualise and configure two identical systems, (a
primary and secondary system), monitoring the same physical links, from within
one OSIX client GUI. With two systems in one GUI, the user is able to select which
system to work with, primary, secondary, or both.

Hardware and software
This chapter describes the hardware used, the software in the network
interface hardware, and the servers.
5.1
Hardware
There are different types of network interface hardware depending on the type of
interface you have at your site; E1/T1, Ethernet, STM1/OC-3.
5.1.1 Probes for E1/T1 monitoring
The LIM 3.0 extracts signalling from E1 and T1 G.703 PCM links in fixed, GSM and
3G UMTS mobile telephone networks. It connects to E1/T1 links, decodes layer 1
and layer 2 of the protocol stack and then forwards the monitored data to the Probe
Server server over TCP/IP.
Each LIM 3.0 provides 64 E1/T1 receivers in 1U of a 19” rack I.e. possibility to
monitor 32 E1/T1 links.
The LIM is controlled by an external application through an OS- and languageneutral text-over-TCP/IP/Ethernet API.
The LIM is capable of decoding SS7 MTP-2, ATM (AAL5 and AAL2), frame relay or
LAPD.
The average link load is limited to 0.4 Erlang. However, peak loads can be up to 1
Erlang.

5.1.1.2
Hardware features
19” x 1U rack-mounted chassis, 482 x 144 x 42mm.
E1/T1 receivers have software selectable E1(2 Mbit/s) or T1 (1.5 Mbit/s) mode,
75/100/120 ohm termination and are compatible with standard -20dB (G.772)
and also -30dB monitor points.
Dual 10/100 Mbit/s Ethernet, both support Power over Ethernet (PoE).
Power consumption less than 10W per chassis. Dual 48VDC power inputs and
dual PoE.
No moving parts, passively cooled.
Measured MTBF: 130 module-years between failures

Hardware and software
Figure 25: LIM 3.0 - front
5.1.1.3
Electrical independency – hot swap
The power converters in each probe chassis accept two separate, polarity
independent input voltages of 38-60VDC. This makes the probe extremely resistant
to variations in power supply.
5.1.1.4
Software independency
All real time critical issues are handled in the hardware, and the software is easily
upgradeable. Upgrades can also be handled remotely.
5.1.1.5
Synchronisation
The OSIX system uses the NTP protocol for time synchronisation. When the probes
have been synchronised they use the PCM links as the timing source, that is, the
system is running at the same pace as the switching system. This assures very
accurate time stamps.
The ntp time-adjustment is continuously monitored and is typically within parts of a
millisecond.
5.1.1.6
Carrier class approved
Each component of the OSIX system is thoroughly tested and approved in
accordance with requirements for CE and EMC carrier class levels.
The probes, and LIMs have also been separately approved for electrical safety,
regarding, for example electrostatic discharge, and surge resistibility according to
ITU-T.
5.1.2 Probes for STM-1
5.1.2.1
STM-1
The probes consist of 1U 19" rack-mounted chassis (482mm x 144mm x 42mm)
with room for one or three independent sub-modules. Each sub-module is equipped
with the following interfaces:
Two SFP sockets for STM-1 SFP modules. Multi-mode and single-mode fibers,
different wavelengths and connectors are selected by the added SFP module.
Two 10/100 Mbit/s Ethernet with RJ-45 connector.
Status LEDs.
The units can be equipped as follows:
SDH 3.0-1 - equipped with one (1) SDH sub-module. NOTE: this version is not
expandable, meaning you need to replace the whole chassis if you need to
increase with additional sub-modules.
SDH 3.0-2 - equipped with three (3) SDH sub-modules. This version is HW
prepared with three sub-modules, and can be upgraded to SDH 3.0-3. This is
managed through a SW license. NOTE: Both a basic SW license and a Pro SW
license is required when upgrading to a SDH 3.0-3.
SDH 3.0-3 - equipped with three (3) SDH sub-modules.
The basic SW license (included) can be upgraded to a pro SW license, which
enables monitoring of more signalling links, as can be seen in the table below.
System Description
OSIX 5.6
32
Hardware and software
A chassis provides two or six SFP sockets in total and thereby monitor both
directions of one up to three SDH links.
Each SDH 3.0 sub-module can monitor two simplex SDH links. The SDH Layer 1
configuration supported is STM-1->AU-4->TU-12. Each sub-module is capable of
monitoring 68 MTP-2 duplex links.

5.1.3 Probes for Ethernet
5.1.3.1
MediaProbe
The MediaProbe is Polystar’s solution and platform for Ethernet monitoring and
analysis of control- and user-plane data in high-capacity data networks.
The MediaProbe offers sophisticated filtering features, and delivers performance
metrics for troubleshooting and for ensuring the quality and high performance of the
service, for example for email, MMS, and streaming and VoIP services. The solution
offers many benefits, among them:
Hardware investment reused during migration from 1 to 10 Gbps
The solution is built on a generic platform with future support for higher
bandwidth
Real time user plane quality analysis
5.1.3.1.1 Connection
The MediaProbe is strategically placed at the various points within the network and
network gateways that allows it to collect 100% of the network data. The actual
connection to the customer network can be made in two ways: either inline using
fibre splitters (1), or using aggregated mirror ports (2).
5.1.3.1.2 Hardware configuration
The MediaProbe offers fantastic flexibility and power as it can be deployed in any
size network, from the smallest to the largest, and can make lossless connections
at 10/100Mb, 1Gb and 10Gb connections. There are two main hardware
configurations, as described in the following sections.
System Description
OSIX 5.6
33
Hardware and software
5.1.3.1.2.1 10/100Mb, 1GbE Monitoring
The MediaProbe package for monitoring 10MbE/100MbE/1GbE is implemented on
standard HP ProLiant servers with standard NIC. One to eight 1GbE ports
dedicated for monitoring purposes.
5.1.3.1.2.2 10GbE Monitoring
For 10GbE Monitoring, Polystar offers two solutions; High-end and Low-end, as
described below. Polystar uses either dual or quad port NICs for this purpose,
depending on the customer implementation of the taping /aggregation of the actual
monitoring links. Each MediaProbe can handle 1-4 links depending of which NIC is
used.
Monitored network connections:
2 or 4 x 10GBASE-SR/LR/LRM/ER, using SFP+ modules
LC connector
High-end and low-end 10GbE Monitoring
To handle 10Gbps physical interfaces, Polystar uses two different NICs, one for
throughput ? 4Gbps and another one for high-end monitoring ? 19 Gbps both based
on the standard PCIe form factor deployed in a HP ProLiant DL 360 server.
In the low-end 10GbE monitoring solution, each HP ProLiant server can be
equipped with two 10GbE interface cards, each with two ports dedicated for
monitoring purposes. A prerequisite for this hardware configuration for monitoring
GTP-U user plane signalling, is that all user plane signalling for one user session is
received on the same interface.
5.1.3.2
Aggregation of user data
The MediaProbe is Polystar’s all-seeing eye, able to collect 100% of the network
data. However, monitoring of all user plane traffic would demand an enormous
amount of processing and storing capacity. Therefore, one of the most important
features of the MediaProbe is user plane aggregation. This represents an efficient
way of monitoring huge data volumes, which is crucial to be able to manage the
requirements of increased bandwidth.
Data volumes are increasing sharply in the packet core network, as more and more
demanding services are offered to users. Consequently, aggregation of user data is
the key method for understanding and analysing performance in high-speed data
networks.
Aggregation can be carried out on several different levels, allowing operators to
control how much they want to invest in hardware for user-plane analysis.
Aggregated data can be presented in Call Trace, and in the Event Analyser in
Jupiter.
5.1.3.3
Aggregation levels
Several aggregation levels exist, each offering different features. Note that it is
always possible to associate the performance metrics back to the subscriber,
enabling for example IMSI and MSISDN tracing, independent of the chosen
aggregation method.
5.1.3.3.1 TEID aggregation
TEID aggregation, or session-based aggregation, is an advanced form of
aggregation of the user-plane traffic. This level of aggregation provides details of
how many bytes and packets that have been sent during the time the session is
active. For long sessions there is a possibility to generate information at regular
intervals, for example every 10 minutes.
System Description
OSIX 5.6
34
Hardware and software
5.1.3.3.2 Flow-based aggregation
The flow-based reporting is based on source/destination IP addresses and
application ports from the UDP/TCP header. Flow-based aggregation is performed
for each individual GTP-U tunnelled TCP and UDP flow and contains details for
each flow, such as bytes/packages sent, IP fragmentation, TCP retransmits, IP
addresses, ports, and more.
5.1.3.3.3 Application-based aggregation
Application-based aggregation extracts additional key parameters from different
application protocols including HTTP, SMTP, FTP and RTSP, and also offer
aggregation capabilities on parameters such as Partial URL or HOST aggregation
of WWW traffic.
Next to traditional KPIs (Key Performance Indicators), such as number of packets
and bytes for throughput calculations, the application-based performance
monitoring also obtains key fields from the protocol headers.
The type of information is protocol- and application-dependent, but, using HTTP
protocols as an example, the additional information includes status/error codes,
User Agent, HTTP version, and content length, which is valuable when analysing
the performance of services and troubleshooting problems.
Examples of supported services and protocols:
WAP (WSP/WTP)
Web services (HTTP)
MMS (HTTP, WAP)
Streaming Services (RTSP)
MAIL (SMTP, POP3, IMAP)
FTP
DNS
Powered with DPI functionality, the MediaProbe analyses and generates
aggregated summaries which are correlated within the Probe Server in real-time to
corresponding control signalling, giving the possibility to analyse individual users
and their activities. For example, a user visiting a specific host, activities performed
by a complaining user, user patterns for VIP customers etc. The aggregated
records containing key parameters from the user plane empowered with control
signalling information (like IMSI, MSISDN, Cell information etc.) are presented
within the Polystar Jupiter application, which contains an extensive set of reporting
capabilities as well as analyse capabilities for each individual aggregate. See the
Jupiter System Description for more information.
5.1.3.4
Aggregated RTP- Voice Quality Analysis
Many VoIP calls will traverse multiple networks, and the service quality is often
affected by circumstances outside the control of the service provider. This makes
VoIP performance management and service quality monitoring critically important.
The voice quality calculation is made in the MediaProbe. Values like MOS (Mean
Opinion Score), Jitter, delay, echo, and packet loss are forwarded to the probe
server.
A MOS value is given for conversation and listening. It is also calculated every 30
seconds (configurable) and at the end of each call. RTCP is a quality report from
the end points/nodes and taken into account if present in the monitored traffic.The
values are presented in OSIX in a separate column.
System Description
OSIX 5.6
35
Hardware and software
5.1.3.4.1 MediaProbe for RTP
By integrating a third-party library into the MediaProbe for RTP, Polystar has
created a voice quality analysis implementation that is P.564 class 1 compliant. It
allows network managers to see call quality problems in real time and identify the
root cause of the problem on active or even completed calls.
5.1.3.4.2 VoIP call quality monitoring
VoIP call quality can be affected by packet loss, discards due to jitter, delay, echo,
and other problems. Some of these problems, notably packet loss and jitter, are
time varying in nature as they are usually caused by congestion on the IP path.
The MediaProbe for RTP can provide call quality metrics, including listening and
conversational quality scores, and detailed information on the severity and
distribution of packet loss and discards (due to jitter).
The columns for Aggregated RTP are available in both Call Trace and Protocol
Analyser. Supported protocols are SIP, SIP-T, H.323, MGCP, and MEGAGO.
5.1.4 Server hardware
As probe servers, Polystar uses DL or BL series HP ProLiant servers. The probe
servers are configured with different RAID configurations, which prevents data loss
in case of hardware failure.
5.1.4.1
Operating system
The probe servers are running CentOS as operating system.
5.1.4.2
Database
The probe servers are using MariaDB as database system.
5.1.4.3
Storage subsystem
Polystar uses HP hardware in the OSIX system. This gives us an extremely wide
range of hardware to choose from, and we can therefore solve virtually every need
for storage.
When extra storage is needed Polystar uses HP D3xxx Storage Enclosure solution.
5.1.5 Performance
The performance limitations of the system are practically none. If the limit of the
implemented configuration, is reached the need for capacity can be solved in
several ways:
Load Sharing - The software can be separated on several hardware servers.
This is possible due to the OSIX architecture. This gives the operator the
opportunity to use hardware already invested in.
Server upgrade – A hardware server reaching its limit can be upgraded or
replaced. The cost for this is limited thanks to the use of standard hardware
servers available on the market worldwide.
5.1.6 Client hardware
Minimum Client PC requirements:
Windows XP SP3/ Windows 7 operating systems
400-megahertz (MHz) processor or faster
4 GB RAM of system memory (whereof 2 GB free for the OSIX application)
System Description
OSIX 5.6

Hardware and software
400 MB of free hard disk space.
See the site requirement documentation for more information.
5.2
Software
5.2.1 Global server
The main task for the Global server is to keep track of all the other servers in the
system. Whenever a new probe or probe server is connected to the system, the
Global server automatically feeds the new server with information about which other
servers/clients to connect to, and all necessary configurations.
The Global server is also logging all the activities in the system, which enables the
system administrator to see the status of all the connections. The configuration and
logging information is stored in a database connected to the global server.
This gives the system high security since the administrator can trace all activities of
the client users and also disconnect client users.
5.2.1.1
Redundant global server
Optional a redundant Global server can be used to minimize downtime and
increase availability if Global server suffers or is degraded by any reason.
Continues replication of configuration data in the background is performed between
the active and the redundant Global server database.
5.2.2 Performance server
The Performance server is usually located on the same hardware as the global
server, and is the engine behind the Mass Call and Performance Analyser
applications.
The Performance server keeps track of the following data required for monitoring
the different Key Performance Indicators:
all the different call attempts to/from different numbers (Mass Call),
the way the different call attempts end (Performance Analyser Circuit (ISUP,
IUP, BICC) ISDN, SIP, Iu-CS),
the conversation time for successful calls (Performance Analyser Circuit (ISUP,
IUP, BICC), ISDN, SIP, Iu-CS),
the number of successful invites and registrations (Performance Analyser SIP),
the number of successful SMS transactions (Performance Analyser Iu-CS),
the number of successful Attach Requests (Performance Analyser GPRS, IuPS),
the number of PDP Activations ended with certain SM causes (Performance
Analyser GPRS, Iu-PS),
the number of successful transactions (Performance Analyser INAP, MAP, IS41),
the number of transactions, and the time interval between the messages in the
transactions (Performance Analyser INAP, MAP, IS-41),

the Min/Max Throughput Downlink/Uplink (Performance Analyser GTP),
and many other things. In short, based on the calling processes picked up by the
probes, the Performance server generates the information displayed in the Mass
Call and Performance Analyser applications.
5.2.3 Probe server
The main task for the Probe server is to:
Extract all the signalling information,
Process and decode the incoming data into protocol messages,
Correlate the messages for the different transactions, or the different
transaction parts for entire logical transactions,
Keep track of the different calling processes taking place in the signalling
network,
Store data for the SOS application.
The probes are connected to one or many of the probe servers in order to support
network wide call correlation, a prerequisite for any global functionality. Probes are
connected to a router server, which will evenly distribute the messages for the
different transactions to the probe servers.
The probe servers also include the SOS (Storage of Signals) database and the xDR
generator.
5.2.4 Third-party software
5.2.4.1
Enhanced technology solutions
Polystar has entered into strategic partnerships with selected vendors that offer
specific, best-of-breed embedded technological solutions that functionally
complement Polystar’s products.
This enables Polystar to deliver solutions that help customers run their operations
more efficiently and differentiate themselves in a competitive market, while
improving their service offerings and finding new ways to drive revenue.
5.2.4.2
DPI
Polystar has embedded a third-party library— an industry-standard software engine
for Deep Packet Inspection (DPI) and L7 application intelligence—into our product
portfolio.
With the Application Performance Monitoring package, the operator will have the
ability to monitor and track the usage, performance and network impact of more
than 1,600 individual applications. This level of granularity is important, as each
application has a different impact on the network and can be monitored individually;
some applications are more vulnerable to latency, while others are more susceptible
to packet loss or TCP retransmits.
The DPI functionality in the MediaProbe uses a protocol library. As more and more
applications enter the market, the protocol library is released on a monthly basis.
Upgrading the MediaProbe with a new protocol library is done without the need of
restarting the MediaProbe.
5.2.4.3
RTP
Polystar uses a third-party library that supports VoIP, IP Videoconferencing, IPTV,
and Video Streaming services.
Through the integration of the third-party library in the MediaProbe, Polystar
provides a solution with a unique ability to monitor VoIP calls with efficient analysis

of multiple parallel packet voice streams as well as QoE call quality scores (MOS
and R-factor).
5.3
Scalability
As described earlier in this document the OSIX system has excellent scalability.
This section describes the possible ways of expanding the system.
5.3.1 New signalling links
New links on an already existing E1/T1 can be added dynamically when the system
is running. Simply activate a new time slot in the Configuration Manager and that
time slot is monitored. There are no interruptions in the traffic on other links.
5.3.2 New sites/countries
When the operator needs to install the system at other sites in the same country, or
in other countries, probe servers and probes according to the number of links
installed at each site. A new probe server or a new probe can be installed and
connected to the global server dynamically. New links and nodes will automatically
be detected in the system and the signalling taking place on the new links will be
monitored.
5.3.3 New users
If a new user needs access to the system, the system administrator configures the
user account, and the OSIX applications are installed on the user’s computer. The
user logs on to the OSIX system with user name, password and global server
name. The global server then automatically downloads all necessary configurations
to the client.
5.3.4 Processing and data storage
Thanks to the distributed system architecture, the OSIX system has a very high
scalability. If additional processing capacity, or extended need for data storage is
required, an additional probe server can be added on one or more sites. The need
for an extra server may occur if an operator decides to store signalling data, or
xDRs, for an extended period of time, or if a new value added application, which
requires a special xDR format, is added to the system. The cost for additional probe
servers is limited since the system uses standard hardware servers. OSIX also
supports load sharing between probe servers, allowing the operator to use the full
capacity of the installed hardware and minimise the cost.

Security
This chapter contains an overview of the handling of passwords, user
authentication, and activity logging in the OSIX system.
6.1
System security management
In the OSIX system, all activities are logged. There is also an easy procedure for
the authorised system administrator to define profiles, user groups, and user
accounts in order to administrate and control the users. The authorised system
administrator can easily see which user accounts are logged on, or locked, and the
current user activities.
6.1.1 Password expiration
For security purposes, user passwords expire after a certain time, and will then
need resetting. It is recommended that the password contain both uppercase,
lowercase and numeric characters. However, this is configurable and not a default
setting.
6.1.2 User authentication and activity logging
All individual users, remote machines and client processes are authenticated before
they are granted access to resources or information. It is also possible to set a
personal, and unique, user identity. Users are automatically logged out if the
communication with the Global server is broken. The system administrator can also
log out the users, for example in case they have forgotten to log out when leaving for
the day, or if someone else with priority needs to log in, etc.
The authentication mechanism is based on conventional password methods, using
the SHA-1 algorithm. These are the same procedures and algorithms as the ones
used in Linux.
Encryption exists between the OSIX client and the Global Server. Secure GCP
socket with TLSv1.2 protocol encryption algorithm is used. The implementation is
done according to RFC 5246 (server authentication with an unauthenticated client).
Network information can neither be accessed nor employed by anyone not
appropriately authorised. Also, it is not possible to bypass the authorisation system
by connecting local equipment or using different client software.
The execution of an operation is dependent on the permissions of the user group
the user is assigned to. Each user group has its own permissions, which defines the
applications and traffic groups the users assigned to the group will have access to.
The logging is done in such a way that logs are never lost during power outings, etc.
It is also possible to log which user identities have used the system at a certain
time, and their activities. The cmactivities.log logs all changes made in the
Configuration Manager, that is all global changes that are affecting the system. The
useractivities.log logs all filter settings made by the user, and information about
export/save activities in Call Trace and Protocol Analyser, that is, time, user, and
export/save (not the actual content).
A search dialog can be enabled per user group. If enabled, users belonging to the
user group will be prompted with a search dialog every time they access traffic in
Protocol Analyser and Call Trace. The reason that the user enters for accessing the
traffic will then be logged.
Different operators with large networks have also tested OSIX with port scanning,
and the outcome has been very satisfying.

Security
6.1.3 Privacy
The Call Trace and Protocol Analyser applications have the possibility to mask A
numbers, B numbers, IMSI, and IMEI numbers. Masking is applied in all modes
(real-time, historical and when opening files). It is applied to all views of the
applications (main window, call window, call flow window and message summary
window). Masking of SMS and USSD is supported. Files exported using format
XML, HTML, or text will be masked. Masking is configured in a privacy profile, which
can be associated with one or more user groups.

System management
The OSIX system contains four means of internal system management;
Configuration Manager, which includes all the important configurations
for the system and is accessible from the OSIX Main Panel,
Log files, which allows you to see which users logged on when, and their
activities in the OSIX system,
System Status, which shows the different connections within the OSIX
system, counters for processes per protocol, xDRs, etc.,
Web Interface to the LIMs, which displays information about the status of
the LIMs, and the low level traffic information and is accessible from a
web browser,
Support server, which allows you to monitor the status of the hardware.
7.1
Configuration Manager
In the Configuration Manager application you can make configurations for user
groups, user accounts, servers, mass call, performance analyser, network maps,
traffic groups, channels, boards, names for protocol parameter values, xDR
generators, protocol packages, state machine, SOS packages, correlation tables,
active alarms, etc.
Figure 26: The Configuration Manager window
7.1.1 Users
The OSIX system supports 50 concurrent users per Probe Server (PRS).
The user configuration is done in three steps; creating profiles, creating user
groups, and creating user accounts. The profile decide the default application setup
the users will have when first logging into the system. The user groups decide which
profile, which licences, and which traffic groups the users assigned to the group
should have access to. In the user account settings you decide which user group
the user should belong to, set up the user’s password, as well as lock/unlock the
account, and log off the user.
System Description
OSIX 5.6
42
System management
When clicking on the Accounts item an overview of all the accounts is displayed,
where you can see which accounts are logged on, which accounts are locked, and
when the user account was last logged in.
By setting up authentication profiles you can use RADIUS as a log in procedure to
the OSIX system.
A broadcast message functionality is also available for sending general messages
to all the users that are currently logged into OSIX.
7.1.2 Mass Call
The Mass Call folder contains all the configurations for the Mass Call application.
You can set different mass call thresholds for calling/called numbers, set different
buffer sizes, and different alarm levels as well as set the time interval.
7.1.3 Performance Analyser
The Performance Analyser folder contains a different set of settings for each of the
protocols available. The settings include call group definitions, call group alarm
settings, and main settings for the overall alarm configuration.
For the alarm settings, intelligent alarm functionality is available, that is, the system
can calculate reasonable alarm settings for selected groups.
All settings can be exported and imported if you wish to edit the settings in another
application, or save a specific configuration for later comparison.
7.1.4 Jupiter
In the Jupiter folder you can configure the Jupiter nodes. The available items are
Web servers, Sites, xDR times Profiles, Aggregation Times Profiles, QSS
Databases, XPS, XPS Groups and Report Packages.
7.1.5 Network
By selecting the Maps item you will be able to configure different network maps for
users to open in the Network Status application, manage the nodes in the network
as well as set thresholds for all the links in the network.
The Traffic Groups item, contain different traffic groups, which will be available for
the users to choose from when starting Call Trace or Protocol Analyser.
The Signalling Channels folder contains one item with settings for the signalling
channels you wish to monitor for each protocol stack; SS7, ISDN, Frame Relay,
Ethernet, ATM over E1, and ATM over STM-1.
The Detected Links item contains all automatically detected SCTP associations and
SS7 links detected within SCTP associations.
The Boards item contains different interface boards used by the system.
Point Code and Global Title mappings are set up in the Point code, Global title
mappings item.
By defining regions, the same point codes can be used for nodes in different
regions.
System Description

7.1.6 Protocols
In the Parameters item attributes/names can be associated with specific values for
different parameters such as calling/called numbers, point codes, HLR/VLR
numbers, IMSI numbers, IP addresses, etc., in the available protocols.
These names will be visible and available when setting filters in the Call Trace and
Protocol Analyser applications. Names for A Numbers and B Numbers will also be
visible in the Mass Call application if the stated numbers/number sequences are
listed.
In the xDR Generators item you will find the xDR Generators which you can use for
setting up different xDR Generators with different formats, and different filter
settings, which can be sent to different systems.
In the Protocol Packages item you will find the Protocol Packages which are used
by the probe server and the client to determine which protocol to use when
decoding incoming messages.
In the State Machine Config and State Machine Timers item you can configure how
calls/transactions are released and edit the timers.
In the SOS Packages item you can configure named sets of complete configuration
parameters that can be assigned to a PRS.
In the Correlation Manager item you can configure mappings for MEGACO-ISUP,
MEGACO-IUA, MGCP-ISUP, ISUP-CAP, and IMS Mobile.
7.1.7 Alarms
The Network item contains settings for all the different alarms that you can view in
the Network Status application. Here you can enable/disable the alarms (which will
also determine if they are sent as SNMP traps or not, if you have support for SNMP
traps), set different severities and change the names on the alarms.
The SNMP item contains all available SNMP profiles. With SNMP profiles you can
group one or more receiver of traps into one entity. Traffic Groups and LIM Groups
are then associated with one or more profiles.
In the Media Probe Alarms item you can define additional alarm configurations for
MediaProbe.

7.2
System Status
With the System Status application you can monitor different parts of the system
itself, such as servers, SOS, routers, CDR-generators, etc.
Figure 27: The System Status Main Window
The tree structure in the left pane of the main window displays a hierarchical
representation of the different parts of the system which you can view the status for.
The right-hand pane of the main window displays a tabbed interface for navigating
among the tables containing status information.
The System Status application includes threshold values for various performance
parameters, all available as SNMP traps. Alarms will, for example, be generated if
the memory utilisations are too high, a component discards messages or fail to
update its current status.
Nodes and subnodes can be disabled per user group, which can be useful when
certain user groups should have limited access to the System Status GUI.
7.2.1 Wrapper solution
Since the components in the Probe Server Subsystem handle a large amount of
data, all down time needs to be kept to a minimum. Each minute one component is
down a lot of transactions (for example, pure messages, xDRs, SOS data,
mappings, alarms) are lost.
The OSIX start scripts use a wrapper solution to monitor and restart components.
There are two reasons that triggers a restart:
A process “dies”
A Java process goes out of memory
The wrapper functionality is visualised in the System Status GUI with restart
notifications for all OSIX components.

Support server
The installation at the customer’s site requires a support server. This server allows
Polystar Services remotely to access the installation for updates and upgrades, as
well as maintenance and troubleshooting.
Additional software may optionally be installed to monitor HP hardware status, for
example, to see if a cable is disconnected, or a hard disk has crashed, as well as
problems with fans, CPU and memory. However, the installation and/or use of this
software cannot be part of any kind of acceptance criteria.
7.4
LIM web interface
The web interface contains information about the status of the PCMs, and the LIMs
configuration. The interface shows Power, Temperature, Ethernet connection
status, CPU load, NTP sync, PCM status layer 1 and layer 2 etc.

8.5.3.1
Circuit
The call groups can consist of any combination of A Number, B Number, OPC,
DPC, Network Indicator, Nature of Address, and CIC. For A Numbers and B
Numbers, wild cards can be used, and a plus sign can be used for a “catch all”
group. Nature of Address is not applicable for call groups for IUP.
8.5.3.2
ISDN
The call groups can consist of any combination of Link, Direction, A Number, A
Number Type, B Number, and B Number Type. For A Numbers and B Numbers, wild
cards can be used, and a plus sign can be used for a “catch all” group.
8.5.3.3
INAP
The transaction groups can consist of any combination of A Number, B Number,
Destination Route Address, Called BCD Number, OPC, DPC, Service Key, Called
SSN, and Calling SSN. For A Numbers, B Numbers, Destination Route Addresses,
Called BCD Numbers, and Service Keys, wild cards can be used, and a plus sign
can be used for “catch all” groups. For Service Keys, you also can enter regular
expressions with different types of wild cards.

8.5.5 Intelligent alarm settings
Setting appropriate alarm levels can be difficult the first time the application is used
in your network. To give you a hint, OSIX can measure the KPI values for the call
groups/transaction groups, and calculate appropriate alarm settings for you, called
“intelligent alarm settings”. You can also select to not have alarms sent if a certain
number is involved in a major part of the call attempts by using the Frequent
number functionality. However, this possibility is not available for INAP Frequency
alarms.
8.5.6 Exporting
If you want to save your settings, or edit them in another environment than in the
Performance Analyser Server Configuration, you may export your group settings,
open them in Excel, and import them back into Performance Analyser later on.
8.6
Mass Call
The Mass Call Application monitors call attempts made to/from specific B Numbers/
A Numbers for the ISUP, IUP, and BICC protocols. There are two main windows with
different focus; calls made to specific B numbers, calls made by specific A numbers.
8.6.1 User interface
In the Mass Call B Number window, you can detect large amounts of call attempts
made to certain numbers, which enables you to reroute calls before congestion
occurs, or detect looping calls. The window displays information about the B
numbers to which the call attempts are made, the A numbers placing the calls, and
the DPC/NIs involved in the call setup.
Figure 41: Mass Call B Number Main Window
In the Mass Call A Number window, you can detect numbers that make large
amounts of call attempts, thus identifying fraudulent behaviour. For example, if a
certain A number places a large amount of call attempts to different B numbers in
sequence, you may suspect that a dialler is being used to hack a switch. The
window displays information about the B numbers to which the call attempts are
made, the A numbers placing the calls, and the OPC/NIs involved in the call setup.

OSIX for mobile networks
OSIX extracts information from signalling networks and includes
applications for monitoring and troubleshooting, xDR generation/SNMP trap
generation, and OSS (Operation Support System) applications. The
following sections show a few examples for mobile networks.
9.1
Protocols and interfaces
OSIX supports all major telecommunication technologies within 2G, 3G, and LTE/
SAE. The system supports a wide range of interfaces and protocols and supports
legacy and state-of-the-art technology; for example, both legacy Gb and LTE. In a
majority of installations, several network topologies are monitored in the same
system simultaneously.
For more information about user plane monitoring in mobile networks, see
5.1.3.2 Aggregation of user data.
For protocol compliance, see the OSIX Supported Protocols document.
All supported protocols have a large set of pre-defined parameters available for
filtering. For information about protocol parameters, see 12 Protocol Parameters.
9.2
Mobile network features
Support for all major GSM/GPRS/UMTS and LTE/SAE interfaces.
Real-time deciphering of Gb and EMM/ESM.
Real-time mapping of TMSI/P-TMSI/GTI to IMSI.
User-plane handling of GTP-U with different levels of aggregation, offers an
effective approach for monitoring huge data volumes. Flow aggregation
enables troubleshooting on individual TCP/UDP flows, including user data
application protocols, for example HTTP, DNS, SMTP, FTP and RTSP. Session
aggregation gives a lower hardware footprint, focusing on key summary
information from user-plane signalling. All user-plane information is correlated
to the corresponding control signalling.
Multi-protocol correlation for voice, text and ongoing/closed data sessions.
Real-time KPI measurements for Iu-CS/Iu-PS/Gb and Gn.
Support for full 10GbE Monitoring.
Automatic detection of SCTP associations/endpoints with map view and
included alarming and status functionality.
9.2.1 Mobile Data Monitoring (MDM)
The system architecture in OSIX is specially developed to handle Mobile Data. The
architectural changes are applied to the GTP and Diameter protocols as of now.
The features are summarised below:
Persistent system components - RTR and PRS components can keep the state
of sessions on restarts.
Binary message data handled on disk instead of server memory - enables
components to handle a higher number of simultaneous transactions.
Searchability for ongoing calls in Call Trace both in real-time and historical
mode.
Multi-protocol correlation for both ongoing and closed sessions.

The Main Window displays the KPIs for the call groups in real time. You can have
one window open per protocol, and the information is updated every ten seconds by
default (this is configurable per client).
Example:
The figure illustrates verification of a new SM-SC. It shows that the average
response time for sending a text message is over two seconds. These statistics can
be investigated further on cause codes in Real Time Statistics or through built-in
drill-down to Call Trace or Protocol Analyser.
Figure 58: The Performance Analyser Main Window for MAP
The Avg Response Time (millis) column indicates serious problems. It can, for
example, indicate under-dimensioned nodes and/or high traffic load.
TCAP KPIs can, for example, indicate that the application layer in an SM-SC is
down.

OSIX extracts information from signalling networks and includes
applications for monitoring and troubleshooting, xDR generation/SNMP trap
generation, and OSS (Operation Support System) applications. The
following sections show a few examples for IMS and VoIP networks.
10.1 IMS/VoIP protocols and interfaces
In a pure IMS environment, there is only a need for three protocols; SIP, Diameter
and DNS. SIP is used for the establishment of multimedia sessions, and Diameter is
used for database communication. DNS is used to find other IMS nodes, but also
for conversion between telephone numbers and IMS URIs. However, when
interworking with legacy networks, the H.248 (Megaco) protocol is essential.
The OSIX system supports all the major protocols; SIP, Megaco/H.248, and DNS as
they are used on a majority of the IMS/NGN interfaces.
All major protocols and links/interfaces used within VoIP networks are supported by
the OSIX system.
For information about supported protocols, see the OSIX Supported Protocols
document.
All supported protocols have a large set of pre-defined parameters available for
filtering. For information about protocol parameters, see 12 Protocol Parameters.
10.2 IMS/VoIP network features
Support for all major interfaces and protocols including extensions, for example
DNS NAPTR.
Multi-protocol correlation with support for matching of for example ICID, SDP
values and A/B numbers.
RTP quality analysis, including MOS score and real-time correlation to
subscriber (SIP dialog).
Real-time KPI measurements for SIP.
Flexible storage of signalling with individual storage length per protocol and SIP
method. That is, INVITE can, for example, be stored for a longer time than
REGISTER.
