3. GSM METRICS

The GSM metrics is defined by a set of GSM key QoS indicator and metrics that helps to have QoS monitoring activity. In order to analyse the performance, the BSS metrics should be created and split into two parts in order to obtain:

BSS Executive Overview: Global views (statistical reference over 1 Week or Month)

Over the entire Network Over BSS zone (One or more BSC).

Performance Metrics: Detailed views (statistical reference over 1 day or Week)

Over specific BSC Site by site analysis.

3.1. BSS EXECUTIVE OVERVIEW

The target of the BSS executive overview is to provide a global view of the QoS perfomance over the entire network or Region. The observation period should be either weekly or monthly. For a weekly report, all metrics (except: CCCHEfficiency_NoPagingResponse%_LAC, GlobalTrafficCarried_All_BSC_BH, BlockingRate%_TCH_CEL and BlockingRate%_SDCCH_CELL See table hereafter) should be a week average value, otherwise the busiest day and the busy hour value should be taken.

A monthly report is composed of each weekly value (week average value/ busiest day at busy hour value). Thus the monthly report will contain 4 values.

AMR Monitoring NetCalc Name Level Description

SubscriberQoS_Indicator_BSC BSC

This metric determines the End user QoS evaluation at BSC level, taking into account call establishment failures, resources allocations failures, handover execution failures and dropped calls.

SubscriberQoS_Indicator_NW NW

This metric determines the End user QoS evaluation at NW level, taking into account call establishment failures, resources allocations failures, handover execution failures and dropped calls.

CCCHEfficiency_NoPagingResponse%_LAC LAC This metric gives the ratio of paging failure at LAC level. It reveals if mobiles are reachable when receiving SMS or MTC.

GlobalTrafficCarried_All_BSC_BH BSC This metric gives an averaged of Traffic carried.

HR_Penetration CELL

The following metric gives the ratio of AMR HR among the total AMR traffic carried (AMR FR +AMR HR) Id:

SignallingFailures_All% CELL This metric gives the ratio of call establishment failure.

BlockingRate%_TCH_CELL CELL

TCH allocation failures due to a lack of TCH including queuing expiration divided by all tch allocations including TCH overflow. It defines the impossibility to satisfy a TCH request (Call set up and Handover).

BlockingRate%_SDCCH_CELL CELL

SDCCH allocations failures due to a lack of SDCCH divided by the number of allocation requests. It defines the lack of SDCCH and reflects the SDCCH dimensioning.

HOInterBSSTCHRatio_ExecutionFailureInc% CELL This metrics gives the ratio of the total incoming inter- BSS handover failures to the total executions. It is useful to detect any bad radio conditions

HOIntraBSSTCHRatio_ExecutionFailureInc% CELL This metrics gives the ratio of the total incoming intra-BSS handover failures to the total executions. It is useful to detect any bad radio conditions.

Note: For each level, some metrics have a different formula. Therefore, it is strongly recommended to use the appropriate metrics for each purpose.

3.2. BSS PERFORMANCE METRICS

The target of the performance metrics is to provide a detailed view of the QoS over the entire Region, a cell or a TDMA. The observation period should be either daily or weekly.

3.2.1 ACCESSIBILITY

This first set of metrics helps to give an estimation of the subscriber difficulties to attempt a call at different levels (BSC or CELL).

Accessibility

NetCalc Name Level Description

CCCHEfficiency_NoPagingResponse%_LAC LAC This metric gives the ratio of paging failure at LAC level. It reveals if mobiles are reachable when receiving SMS or MTC.

CSPagingSuccess%_LAC LAC This metric gives the ratio of CS paging success at LAC level. It reveals if mobiles are reachable when receiving SMS or MTC. Ts2, Ts4 or Ts6 is used to broadcast paging when Extended CCCH feature is activated.

Paging_All_LAC LAC This metric determines all paging request sent on Air interface.

RACH_LevelNok CELL This is metric gives the average level of un-decoded RACH. It is a good indicator to detect jamming interference or hardware problems. The result is given in dBm.

CCCHEfficiency_ImmediateAssignFailure% BSC/CELL This metric helps to determine the ratio of RACH (decoded by the BTS and sent to the BSC) which have not found a suitable resource.

ImmediateAssign_All BSC/CELL This metric gives the number of suitable resource found and allocated by the mobile after the Immediate assignment message is sent by the BSC.

SignallingFailures_All% BSC/CELL This metric gives the ratio of call establishment failure.

EstabIndic_All BSC/CELL This metric gives the number of suitable resource found and allocated to the mobile after the Immediate assignment message is sent to the mobile and the receipt of the establish indication message sent to the BSC.

SignallingFailures_AbnormalCauses% BSC/CELL This metric gives the ratio of call released during the signaling phase of the call process by the total establish indication messages. It determines The SDCCH drop ratio

TCHAssignment_Nok%_All BSC/CELL This metric gives the ratio of the Assignment failure by the Total Assignment Commands in the cell.

TCHAssignment_Cmd_All BSC/CELL This is the total number of Assignment Commands both EFR and AMR in the cell.

Allocations_SDCCH_Lack_CELL BSC/CELL This gives the number of failures caused by a lack of SDCCH resources.

Service_Denied BSC/CELL This is a subscriber perceived metric and intends to capture instances when a subscriber attempts to establish a call but the voice channel assignment fails.

To have a fine tuned network analysis, the following set of metrics helps to identify the TRX mainly involved on assignment failure degradation.

Accessibility

NetCalc Name Level Description TDMA_TCHAssignment_Cmd TDMA This is the total number of Assignment Commands both EFR and AMR at TRX level.

TDMA_TCHAssignment_Nok% TDMA This metric gives the ratio of assignment command message sent without reception of assignment complete message from MS for AMR and standard FR calls.

Note: To get in observation report the link between the TDMA and the TRX, all TDMA metrics should be monitor with the following metrics:

TEI_ALLOCATION and NB_TDMA_CONFIGURATION

3.2.2 RETAINABILITY

A subscriber who attempts a voice call has to be retained till the end of his call. The aims of this chapter is to list a set of metric which helps to give an estimation of both the call drop and the handover process, which have a great impact on the quality of service.

This first set of metric should be monitored at BSC and/or CELL levels.

CallDropRatio_SystemCauses_CELL CELL This is used to determine dropped calls ratio that are not the direct result of the RF environment at cell level. It might be related to terrestrial circuits like PCM links, SCCP Disconnection etc.

4. GPRS/EDGE METRICS

These Metrics are defined by a set of GPRS and EDGE key performance indicators that helps to have QoS monitoring activity. In order to analyse the globale performance, the Data Metrics should be created and split into two parts in order to obtain:

Data Executive Overview: Global views (statistical reference over 1 Week or Month) over the entire Network or BSS/PCU zone (One or more BSC/PCU).

GPRS/EDGE Performance Metrics: Detailed views (statistical reference over 1 day or Week) over specific BSC/PCU or Cells by Cells analysis.

4.1. DATA EXECUTIVE OVERVIEW

The target of the Data executive overview is to provide a global view of the data perfomance over the entire network or Region. The observation period should be daily, weekly or monthly. For a weekly or monthly overview, all metrics should be a week or month average value, otherwise the busiest day and the busy hour value should be taken.

A monthly overview is composed of each weekly value (week average value/ busiest day at busy hour value). Thus the monthly overview will contain 4 values.

4.2.2 ACCESSIBILITY

This section aims at providing metrics to monitor the failure rate of UL and DL TBF establishments that gives an estimation of the subscriber difficulties to access the network ressurces in order to transfer data. Moreover, in order to determine the root cause of UL and DL TBF establishment failures, causes are classified into two categories:

Allocator: the PCU cannot provide enough resources (in term of USF, TFI, blocks), or its SPM cards are too loaded, to establish a TBF, so the request is rejected.

Radio: the PCU has allocated some resources to one MS, sent an assignment message but no answer is received from the MS due to radio problem.
