FAS Functionality
(Frequency Allocation Support)

The interference level in GSM networks has to be kept to a minimum in order to
use the frequency spectrum in an efficient way, and to increase the capacity of the
network.

FAS can be used to identify poor frequency allocations and thereby limit network
interference

By monitoring the up- and downlink interference environment in the network, FAS
can find bad frequency allocations for BCCH and TCH carriers, and replace them
with better ones

FAS also supports updating of a planned area in Cellular Network Administration
(CNA) with frequency changes.

Recording initiation:
– Cells/BSCs are selected
– Frequencies to measure on are selected
– Time schedule is selected
– OSS sends recording request to the BSC
– Uplink and downlink are measured
– Results displayed in various reports
© Ericsson AB 2011 LZU103 1014
Figure 2- 17

FAS


Uplink: BSCs send requests to
BTSs, to measure UL
interference levels on specified
frequencies. These
measurements are carried out
by the TRXs and the uplink
interference from both packet
switched and circuit switched
MS’are included in the result.
BSCRIR
BAR
Downlink: Interference
measurements are based on
measurement reports sent by
the circuit switched MS’. These
measurements are used to
create an ICDM from which the
PIT is calculated for the
downlink.

Reports
One FAS recording can perform interference level measurements on up to
150 frequencies in at least 2000 cells

Introduction to OSS-RC for Performance Mangement
FOX Functionality
(Frequency Optimization eXpert)

FOX is built upon FAS, with the extra function of recommending
and/or implementing changes.

FOX has the additional functionality of proposing changes that will
improve the network quality by using an algorithm that takes all
possible frequencies in all cells into account, and suggests the
best changes for the cells included in the recording

The results from interference measurements and steering
parameters are the input to the frequency reallocation search
algorithm and a list of suggested frequency reallocations is the
output.

There are two levels of FOX recordings:
–
–
Recommended
Automatic

Figure 2- 20
Introduction to OSS-RC for Performance Mangement
SYROX Functionality
(Synchronized Radio Network Optimization eXpert)

Recommends how certain frequency hopping parameters should
be set for a group of synchronized cells in order to minimize the
interference between the cells.

An ICDM measured by FAS is used as input for the SYROX algorithm,
together with at least one synchronization cluster

SYROX can assign frequency-hopping parameters to all cells in a
network so that very strong interference is avoided and the remaining
interference is smeared out.

SYROX will provide a list of recommended parameter settings for the
cells so that very strong interference is avoided and the remaining
interference is smeared out

NCS-GW Functionality
(Neighbouring Cell Support GSM-WCDMA)

GWNCS supports the user in finding the most appropriate set of
WCDMA neighbour cell relations for each cell in the GSM network

NCS-GW together with NCS-G makes it possible to perform combined
measurements of both GSM and WCDMA neighbouring cells in one
recording.

Data from surrounding WCDMA cells is collected and statistics are collected
about the performance of already existing WCDMA neighbour relations.

The handover decision in a radio network is based on measurements from the
MS on the downlink and from the BTS on the uplink

Several different reports can be generated and are then analysed by the user

It is possible to add and remove WCDMA neighbour cells in CNA via a
GWNCS Change Order and CNAI

NCS-W Functionality
(Neighboring cell support WCDMA)

NCS-W keeps the neighbour relations in the WRAN optimized by
finding missing neighbouring cells relations and finding currently
defined neighbour relations that can be removed.

Only neighbour relations between WCDMA cells using the same
frequency can be optimized with NCS-W

UE continuously monitors cells that are defined and undefined neighbors.

The UE is configured to evaluate and send measurement reports to the
system only when certain events occur (event-triggered reporting)

Events are collected by the GPEH function in the RNC

Various reports are generated and changes can be implemented using
the WRAN CM

MRR-W Functionality
(Measurement Result Recording WCDMA)

The feature concept is to collect statistics from the UE, RNC and
RBS

WMRR initiates the WMRR recording function in the NE, process the
recorded information and present the data in reports.

Similar to MRR-G but measurement results are sent from the RBS and
received by the RNC.

FFAX-W Functionality
(Find Faulty Antenna eXpert WCDMA)

Visualises the performance of the antenna system at every
cell/sector.

The data is collected from the antenna receive branch on RBS and
processed in OSS-RC.

Measurements are collected in xml files and data is presented in
reports

RNDBI
(RNO Database Export Interface)

RNDBI enables a function that exports FAS, NCS-G, MRR, NCS-GW
or TET results and puts them in an SQL relational database.

Any report generator can be used to create reports

Users can customize the presentation of the results to a very high degree

RNDBI makes it possible to combine RNO data with other PM and CM
data stored in other relational databases

Export can either be:
–
–
set at recording scheduling (automatic when the result is finished)
be initiated manually on an existing result
