Technical Description
3.1
Architecture
Ericsson Network Manager (ENM) is an OSS (Operations Support System)
platform, and suite of Network Management applications supporting operation
and maintenance of Radio, Transport, and Core Networks.
ENM comprises a suite of different management applications supporting
the various elements associated with management of faults, configuration,
administration, performance and security of nodes in the radio Network. ENM also
contains more advanced management applications, focusing on automation.
Applications are controlled by human interfaces (GUI and CLI) or machine
interfaces, this varies from application to application. All applications support
integrated online help. This online help contains overviews, tutorials and videos to
help explain common network operations.
Reference [1] gives a description of the ENM product.
The ENM platform is a distributed software system and is accessed via a web
browser.
The applications in ENM can be divided in three categories:
— Common applications, which are used for more than one network domain or
network element type
— Domain-specific applications, which apply to a single management domain
— System or infrastructure applications
Baseband Radio Node supports all radio technologies and is therefore managed
mostly by common applications. For Baseband Radio Node, deployment is
described in Reference [7] and management of a GSM radio network is described
in Reference [8].
BSC are partly managed by common applications and partly by domain-specific
applications. RBS 2000 and DU Radio Node basestations are managed as part of
the BSC.
Figure 1 gives an overview showing in the upper part types of applications in
ENM and the connections to BSC and Baseband Radio Node. The WinFIOL client
application in ENM creates either an MML session to the AP in BSC for access to
CP in BSC or an AP session to access the BSC Managed Object Model (MOM) with
Ericsson Command Line Interface (ECLI). Model based ENM applications, for
example Topology Browser and CMEditor, uses the node models for operations
and maintenance activities.

User Description, GSM RAN Operation and Maintenance for ENM
Baseband Radio Node and BSC are modeled as separate nodes in ENM. DU Radio
Node and RBS 2000 basestation are not modeled as nodes in ENM, instead they
are represented as Managed Objects (MOs) in the BSC MOM.
See Reference [6] for more details on how to access the AXE based BSC node and
more information regarding session types for accessing the AP.

Applications in ENM for GSM RAN Node
3.2.1
General
The ENM Operators Guide, Reference [3], contains general application information
to provide an overview of the context in which specific applications operate. It
also contains information specific for management of the AXE based nodes in
ENM, for example BSC.
3.2.2
Fault Management
There are several applications in ENM for handling of Alarms and all of them are
applicable for GSM RAN Nodes (BSC and Baseband Radio Node).
The following applications are valid for BSC and Baseband Radio Node:
— Alarm Monitor
— Alarm Overview
— Alarm Routing
— Alarm Search
— Alarm Supervision Status
— Automatic Alarm Handling
— Network Viewer
— Node Monitor
The following applications are valid for Baseband Radio Node:
— Network Health Analysis
— Network Health Monitor
— Node Health Check
3.2.3
Configuration Management
Applications in ENM for Configuration Management are based on a MOM from
the nodes. When the value of a MO is changed in ENM, the content of the model
is transferred to the Node. For a BSC the model is in the AP and the changes are
finally transferred to the BSC CP. Changes in CP can be synchronized back to the
model in AP and transferred to ENM, see Reference [4]. Reference [10] describe
how the BSC Managed Object Model is designed. Mapping between MOM and
MML commands for BSC is described in Reference [12].

3.2.4
Performance Management
The PM Initiation and Collection (PMIC) application collects performance
information from BSC and Baseband Radio Node. The data is converted to text
files and files are available in PMIC for processing outside ENM. The information
from BSC can be STS Counter Data, Recordings, Performance Events or Real
Time Trace Events.
Subscriptions for BSC Performance Events and Real Time Trace events are
created in ENM in PMIC tool. These are transferred to BSC using BSC Managed
Object Model (MOM) as described in Section 3.2.3 on page 7. More information on

369/1553-HSC 103 12/43 Uen A | 2021-10-29
Technical Description
model based performance management for BSC is in Reference [5]. See Reference
[9] for further information on PMIC and Reference [13] for further information on
BSC Performance Events and Real Time Trace (RTT).
Subscriptions for collecting BSC recordings are created in PMIC. PMIC supports
collection, decoding and storing of the following BSC recordings: BAR, CER, CTR,
MRR and RIR. These recordings can be initiated via WinFIOL, see Reference [9].
BAR, MRR and RIR recordings can also be initiated from the BSC MOM, see
Reference [24] for more information on how GSM RAN Recordings can be handled
with ENM.
MTR recordings are initiated in MSC from PMIC, and are collected from BSC.
Reference [21] gives an overview of STS Counter Data handling, the counter data
is analyzed in the ENIQ tool outside of ENM-application PMIC.
ENM application that is applicable for both BSC and Baseband Radio Node:
— PM Initiation and Collection (PMIC)
The following applications are applicable for Baseband Radio Node:
— KPI Management
— Spectrum Measurement Management
3.2.5
Security Management
Operations and Maintenance access to an GSM RAN Node is controlled by
assigning users needed roles in security infrastructure.
Reference [1] includes an overview of the Security in ENM and applications used
in managing Security for ENM and connected nodes. ENM Identity and Access
Management is described in Reference [22].
When Ericsson CLI (ECLI) is used for connection to BSC or Baseband Radio
Node, centralized user management controls which users that are allowed to
perform O&M activities on the node. Centralized user management requires a
central LDAP directory server. Details for Baseband Radio Node can be found in
Reference [15], for BSC in Reference [10] and Reference [16].
ENM applications that are applicable for both BSC and Baseband Radio Node are:
— Node Security Configuration
— PKI Entity Management

Engineering Guidelines
4.1
Activation
Activation of BSC Model Based Configuration Management is described in
Reference [10].
Management of BSC events from ENM is described in Reference [13]. More
information on how to handle GSM RAN Recordings BAR, MRR and RIR with
ENM, see Reference [24].
4.2
Security
IP security aspects for the interface between ENM and GSM RAN are discussed in
Reference [14] and in Reference [9].
4.3
Limitations
Do not use MML commands to change name on existing cells, MSCs, PLMNs or
PSTU when BSC Model Based Configuration Management is activated in the BSC.
Renaming with use of MML commands will lead to data corruption in the MOM.
To remove the corrupted data, deactivation and activation of BSC Model Based
Configuration Management is needed to align data in MOM data on the BSC CP.
See Reference [10] for a general description and Reference [11] for an example.
4.4
Migration
Migration from OSS-RC to ENM is supported by utilities in ENM, see Reference
[23].
