1. ABOUT THIS DOCUMENT

1.1. OBJECT

This document describes BSS GSM and Nortel algorithms and parameters from an engineering point of view.

This document is written by Nortel BSS experts and contains extensive Nortel BSS parameters setting know-how. Informations coming from experiments, studies, simulations are also related in the document.

The parameters are called by the name used in the features and algorithms. For their corresponding name (when different) at the OMC, refer to [R6].

The parameters described in this document are the ones used in the features and algorithms. Refer to [R2] to have a description of ALL BSS parameters.

1.2. SCOPE

This version is compliant with the V16.0 ChR BSS GSM release.

1.3. AUDIENCE FOR THIS DOCUMENT

Draft and preliminary: Nortel R&D, PLM and Eng'

Standard: customers and Nortel R&D, PLM and Eng'

1.4. DISCLAIMER

Depending on particular objective, call profile and network characteristics, a parameter setting can never be judged as being universally optimized.

The recommended setting presented in this document should result in good network performance; however several iterations and improvements may be required in order to be optimal according to customer specificities. Every effort is made to incorporate suggestions and feedback received from customers.

PRELIMINARY VERSION

The recommended setting has been validated with product and system tests in lab. This document will be updated and adjusted after the first results from VO site or new Product Test/End-to-end labs if available.

STANDARD VERSION

This is a living document and the contents will be modified based on feedback received from R&D, Engineering and customers.

1.5. DOCUMENT STRUCTURE

In chapter CLASSIFICATION OF BSS PARAMETERS, BSS algorithm parameters are presented in alphabetic order according to their group. Process and related objects are also provided.

Chapter ALGORITHMS describes the GSM Nortel BSS algorithms and recommends ways to use them efficiently.

BSS parameters used in the algorithms are described in chapter ALGORITHM PARAMETERS. For each parameter, a recommended value and a default value are given. Engineering rules explain how to select the parameter value.

In chapter ENGINEERING ISSUE, engineering issues resulting from studies on parameter setting and on products, simulations and experiments are developped.

Chapter APPENDIX A: MAIN EXCHANGE PROCEDURES AT BSC LEVEL gives the main exchange procedures at BSC level.

In chapter APPENDIX B: ERLANG TABLE, an Erlang table presents the maximum offered load according to the number of channels and the blocking rate.

In chapter ABBREVIATIONS & DEFINITIONS, the signification of all the abbrevations used in this document and some key-definitions are explained.

1.6. PARAMETERS MODIFICATION

1.6.1 BETWEEN V15.1.1 AND V16

amrReserved1:

This new parameter was introduced to enable/disable RATSCCH procedure for AMR FR. Recommended value set to 0 (enable RATSCCH procedure)

hrCellLoadEnd

New recommended value set to 60, instead of 5 or 10 in urban areas and 50 or 60 in rural areas. Now the value depends on the number of DRXs on the cell.

hrCellLoadStart

New recommended value set to 80, instead of 70 or 80 in rural areas, and 20 or 30 in urban areas. Now the value depends on the number of DRXs on the cell.

1.6.2 BETWEEN V15.1 AND V15.1.1

hrCellLoadEnd:

New recommended value set to 5 -10 in urban areas and 50 - 60 in rural areas, instead of 0

hrCellLoadStart:

New recommended value set to a fix value i.e 20-30 in urban areas and 70-80 in rural areas instead of a value greater than 0

hoMarginTrafficOffset:

New recommended value set to 6 instead of 2; HoMarginTrafficOffset should be tune such as the resulting margin should be equivalent to the one for rescue HO.

early classmark sending:

New recommended value set this value to Allowed even if dual band network is not used. This parameter allows MS to send its capacity downlink Advanced Receiver performance.


Nortel confidential


1.6.3 BETWEEN V15.0 AND V15.1.

RadioLinkTimeOut:

New recommended value set to 32 instead of 20. when AMR is activated RLT drop calls contribution is usually much higher in coverage limited or rural areas because calls are being dragged at cell edges and the overlap between neighboring sites is less important than in urban areas. This recommendation helps to reduce the contribution of RLT drop

Rlf1:

New recommended value set to 7 instead of 4. This new recommendation is linked to RLT one when AMR is activated

HoMarginBeg:

New recommended value set to 2dB instead of 4 when Automatic Handover Adaptation is activated. This new setting helps to get effective margin of 6 dB

AllocPriorityTimer:

New recommended value set to [5 0 5 5 0 0 0 0 28 28 28 28 28 28] instead of [0 0 3 0 0 0 0 0 28 28 28 28 28 28].

AllocWaitThreshold:

New recommended value set to [n 0 n n 0 0 0 0 5 5 5 5 5] instead of [0 0 n 0 0 0 0 0 5 5 5 5 5].

CallReestablishmentPriority:

New recommended value set to 15 instead of 16.

IntraCellHOIntPriority:


DirectedRetryPrio:

New recommended value set to 17 instead of no recommended value.

biZonePowerOffset:

New recommended value depends on the engineering rules, in v15.0 it was 63 dB for monozone and 3 dB otherwise.

ConcentAlgoMsRange:

New recommended value set to 34 instead of depending on the radius of the site.

Small to large HO priority



Nortel confidential


T3103

New recommended value set to 9 seconds instead of 5. From a handover perspective it is recommended to use 9s in order to offer a wider window of good completion of the procedure at cell edge where the quality might be poorer.

noOfBlocksForAccessGrant

Addition of a recommended value for SI2Quater or/and SI13 on ext BCCH.

Data non transparent mode

New recommended value set to TBD instead of 9.6kb/s

Serving factor offset

New recommended value set to 0 instead of -2. It means it will actually favor the server or disfavor in order word the neighbor greatly.

amrReserved2

New recommended values will depend of in what is base AMR alarm handovers and AMR power control. Old value was 3.

amrFRIntercellCodecMThresh

New recommended value set to 10k2 instead of 6k7.
