GERAN RADIO FT GROUP INDICATORS (GMS, GPRS & EDGE)
Version:V5.5 Pages: 62
LEVEL: MANDATORY
Executive summary This document defines the Radio GSM, GPRS & EDGE key performance indicators of the Orange Group, featuring KPIs for the different official FT Group suppliers: Alcatel, Nortel, Nokia, Motorola, Ericsson, Huawei and ZTE. This version of the document contains some updates in some Ericsson, Huawei, ALU and NSN KPIs in order to be more accurate as well as more representative of the user perception. A new CSSR speech user perception formula for Ericsson has been added in this release of the GERAN document.
The update of this document has been done on the basis of the received feedback from MCos , discussions with MCos as well as issues and questions raised by MCos. In addition, SDCCH DROP RATE and TCH ASR (sub KPIs of CSSR) and DCR KPIs for Ericsson, Huawei and NSN have been provisionally agreed with DT.
All the changes as well as contributors are listed in the document history.

1. INTRODUCTION
Each indicator table contains the following information: Indicator name Definition Unit Goal Granularity Periodicity Calculation rules Formula for the 6 official GERAN FT GROUP vendors, if available Comments A network status indicator is used in order to measure the Radio Access Network characteristics. There is no associated target or objective. A performance indicator is used to measure the performance of the Radio Access Network.
This document defines the Radio GSM indicators for the Orange affiliates. The indicators’ definitions in this document are mandatory for the Orange European controlled affiliates. A network status indicator is used in order to measure the Radio Access Network characteristics. There is no associated target or objective. A performance indicator is used to measure the performance of the Radio Access Network. N/A in this document stands for Not Applicable. In case of difficulties when more than one vendor coexist, we suggest the calculation rule to be based on a weighted average for the different vendors. For example we have 20% of traffic of vendor A equipment and 80% on Vendor B equipment. The agregated KPI is calculated as follows:
KPIAgregated = 20% KPIVendor A + 80% KPIVendor B

NSN – description corrected Huawei – new formla for traffic at BH Section 3.1 – Huawei – formula modified for GBSS 12 & 13 Section 3.2 – Huawei – definition based on counters added Andre Garcia, Krzysztof ZTE KPIs have been introduced. Konowalski, Maciej Section 2.9. SDCCH Blocking Rate part modified (blocking on the Urbanowicz ccch reflected) for NSN Contributors: Section 2.11 New formula for NSN DCR – only drops between Marcin Zwolak, Karim Assignemnt Complete and RF Channel Release included. Tafer, Ulas Ozkan, Nicolas Section 2.17 – 2G AMR Assignment Ratio fomula for HUAWEI has Steyaert, Herve Dieudop been included Kouahou, Christian Bellet, Section 3.3 and Section 3.4, throughput formulas for GPRS and Paulo De Almeida EDGE for ALU have been modified (the same approach as for Ferreira, Zakaria SaissiHUAWEI and NSN has been taken) Hassani Maciej Urbanowicz Contributors: Firas Hammad, Ahmed Majt, Marcin Zwolak, Mircea Ionescu
Corrected the “2G Call Setup Success Rate-Speech” KPI for Ericsson and (Section 2.9), Congestion Time KPI for Ericsson (Section 2.14) and AMR Assignment Requests Ratio KPI (Section 2.17) for Ericsson. Corrections were made to get more acurate results. Additionally, formulas for EDGE and GPRS throughputs per TSL for Huawei have been updated (Sections 3.3 and 3.4) Maciej Urbanowicz KPIs for 2G DATA Traffic Volume have been included - sections 3.6, Contributors: 3.7, 3.8, 3.9. Yves Lebrasseur, Herve Section 2.11 - formula for Motorola corrected.

Akhdari Khaled EL KADI & Jude Minor corrections to the Nortel KPIs in sections 2.7, 2.8 & 2.9. SALDANHA Change in the Number of Congested Cells formula for Huawei. Jude SALDANHA, Changed the “2G Call Setup Success Rate-Speech” KPI so that all Contributors : Jerome SDCCH access failures are removed. This gives an optimistic view Vincent, Samuel Guillon, of the CSSR but it is a more accurate reflection of the user Mounir Boti, Olivier Fabre, experience compared to the old CSSR KPI. Sebastien Jayles, Isà Ramandasoa, Marcin Defined a new “2G Call Setup Success Rate-Speech, User Zwolak, Carlos Felipe Perception” KPI that includes SDCCH establishment failures except Fernández Cubero, Firas for those that occur during location updates. This new KPI is Hammad, Daniel Lugo, currently not supported by all the vendors, but with the exception of Vladislav Ciernik, Michal Ericsson the required counters will soon be available in BSS Lewicki, Katherine software releases deployed in the field.
