2. GENERAL

2.1. PURPOSE OF QOS INDICATORS

An indicator is a value based on one or more observation counters and that is representative either of system performance (BSS) or subscriber’s point of view. The counters are either assigned to the system itself or to analysers external to the system. The service quality indicators have five major purposes:

• Identify occasional faults on a subsystem (BSS, BTS) and establish corrective action (operating instruction or corrective maintenance) required to restore service quality;

• Detect and identify recurrent system faults to define corrective action and/or palliative action;

• Detect and identify radio problem on a cell, to help Radio Tuning teams to analyse radio situation and define corrective action (new frequency, antenna modification, parameter adjustment, ...);

• Monitor system changes in terms of : - load - efficiency - traffic model - gain obtained by a software update or network modification;

• Predict network behavior according to traffic evolution (undersizing, overload, etc.).

2.2. TYPES OF QOS INDICATORS

Two main groups of QoS indicators have been identified to meet the above objectives: • Global BSS network surveillance indicators: These are used to indicate the quality of service provided to subscribers and

identify failures and their causes for the entire network and for each BSS. These counters should be managed at the NSS or BSS level, we will discuss here about BSS level only ;

• Detailed BSS surveillance indicators: they are used to identify the causes of individual failures for each BSS and each cell. This can be used to isolate local problems in a subsystem (for corrective maintenance purposes), generic failures due to a specific software version, or appreciate subsystem loads.




2.3. OVERVIEW OF QOS INDICATORS DIFFERENCES BETWEEN B9MR 4 AND B10 MR2

2.3.1. IMPROVEMENT 1: MULTIPLE CCCH

This feature aims at increasing GSM signaling capacity in Dense Urban Areas (paging, SMS...) by allowing operator configure more than one CCCH timeslot. It is required to support the increasing signaling load on the common channels, due to either big CS cells with high peak throughput or to PS traffic when no master PDCH is configured. The introduction of this feature, as B10 optional feature, leads to introduction of nine new counters. The new counters were introduced in MC925 family:

• MC925a (type 110): NB_AGCH_USEFUL_BLOCKS_SENT that indicates the number of useful blocks sent on AGCH channel (The dummy blocks are not counted).

• MC925b (type 110): NB_PCH_USEFUL_BLOCKS_SENT that indicates the Number of useful blocks sent on PCH channel (The dummy blocks are not counted).

• MC925c (type 110): NB_BUSY_RACH_SLOTS that indicates the number of busy RACH slots. • MC925d (type 110): NB_CHANNEL_RQ_RADIO that indicates number of channel request messages received on

the radio interface or number of access bursts successfully decoded. • MC925e (type 110): NB_ASSIGN_CMD_RECEIVED_ABIS that indicates the number of 48.058 IMMEDIATE

ASSIGN COMMAND messages received by the BTS on Abis and had to be sent for CS and PS traffic to the MS. • MC925f (type 110): NB_ASSIGN_CMD_DISCARDED that indicates the number of 48.058 IMMEDIATE ASSIGN

COMMAND messages received by the BTS on Abis and discarded due to congestion. • MC925g (type 110): NB_PAGING_CMD_RECEIVED_ABIS that indicates the number of PAGING COMMAND

received by the BTS on Abis and had to be sent for CS and PS traffic to the MS. • MC925h (type 110): NB_PAGING_CMD_DISCARDED that indicates the number of PAGING COMMAND

received by the BTS on Abis and discarded due to congestion. • MC930 (type 110): NB_ABIS_PAGING_MESSAGE_RECEIVED that indicates the number of PAGING

COMMAND / MULTIPLE PAGING COMMAND message received by the BTS on Abis.

2.3.2. IMPROVEMENT 2: MX BSC CAPACITY IMPROVEMENT

This feature is split into the following sub features: − 1000 TRX MX BSC capacity - In B10 the capacity of a CCP board is kept unchanged (i.e. it supports up to 200 TRX); the capacity of the MX BSC is extended to 1000 TRX by adding 2 CCP boards in the ATCA shelf. The TP GSM board shall support the traffic of 1000 TRXs. − Removal of HR impact on BSC connectivity - The maximum number of TREs mapped to a CCP shall be independent on whether the TREs are FR or DR. It shall be always possible to map up to four TREs (FR and/or DR) per VTCU, i.e. up to 200 TREs per CCP. VTCU can handle up to 4 RSL whatever the speech rate is (FR and/or HR) and so NbTRXeq = NbTRX − Up to 500 cells per MX BSC: The MC BSC capacity is extended from 264 cells to 500 cells. The introduction of this feature leads to introduction of one new counter:

• MC926 (type 110): TCH_BLOCKING_OCCURENCES_BSC that indicates the number of TCH channel allocation rejected for cause: Maximum TCH processing capacity of CCP reached.




2.3.3. IMPROVEMENT 3: DUAL TRANSFER MODE

The dual transfer mode feature has been introduced in 3GPP standard in order to simplify the internal architecture of the MSs and offer services that demand the simultaneous existence of a CS connection and a PS session. The introduction of this feature, as B10 optional feature, leads to introduction of six new counters. The new counters were introduced in MC927 family:

• MC927a (type 110): NB_DTM_UL_TCH_ASS_ATPT that indicates the number of UL TBF establishment attempts in DTM with reallocation of the TCH (sending of DTM Assignment Command with UL TBF).

• MC927b (type 110): NB_DTM_DL_TCH_ASS_ATPT that indicates the number of DL TBF establishment attempts in DTM with reallocation of the TCH (sending of DTM Assignment Command with DL TBF).

• MC927c (type 110): NB_DTM_UL_PACKET_ASS_ATPT that indicates the number of UL TBF establishment attempts in DTM without reallocation of the TCH (sending of Packet Assignment Command with UL TBF).

• MC927d (type 110): NB_DTM_UL_PACKET_ASS_ATPT that indicates the number of DL TBF establishment attempts in DTM without reallocation of the TCH (sending of Packet Assignment Command with DL TBF).

• MC927e (type 110): NB_DTM_UL_TCH_ASS_EXEC_FAIL_RADIO that indicates the number of UL TBF establishment in DTM with reallocation of the TCH - execution failures due to MS access problem.

• MC927f (type 110): NB_DTM_DL_TCH_ASS_EXEC_FAIL_RADIO that indicates the number of DL TBF establishment in DTM with reallocation of the TCH - execution failures due to MS access problem.

2.3.4. IMPROVEMENT 4: PCS REQUIREMENTS

In B10 were introduced a new set of counters related with counters/indicators proposed by NE:

1. End to End Call Setup Success Rate The goal is to provide a new metric, giving a view of the call setup success rate from the end user point-of-view. This means that the event “call established” would be compared to the event “call requested”, instead of combining metrics related to the protocol mechanisms like it is done until B9 (SDCCH drops, TCH allocation and assignation, etc.) The introduction of this metric leads to introduction of one new counter: • MC191 (type 110): NB_SMS_PP_CON_MT_SDCCH that indicates the number of Mobile Terminating SMS

connections on SDCCH.

2. Call Drop with specific radio causes This feature consists in associating a specific radio cause (too low level, too bad quality, etc.) to each call drop radio or call drop handover. The introduction of this feature leads to introduction of nine new counters. The new counters were introduced in MC928 family: • MC928a (type 110): NB_TCH_DROP_CAUSE_TOO_LOW_QUALITY_UL that indicates the Number of TCH

drops due to Cause 2 (Too low quality in UL). • MC928b (type 110): NB_TCH_DROP_CAUSE_TOO_LOW_LEVEL_UL that indicates the number of TCH drops

due to Cause 3 (Too low level in UL). • MC928c (type 110): NB_TCH_DROP_CAUSE_TOO_LOW_QUALITY_DL that indicates the number of TCH

drops due to Cause 4 (Too low quality on the downlink). • MC928d (type 110): NB_TCH_DROP_CAUSE_TOO_LOW_LEVEL_DL that indicates the Number of TCH drops

due to Cause 5 (Too low level in DL).




• MC928e (type 110): NB_TCH_DROP_CAUSE_TOO_LONG_MS_BS_DISTANCE that indicates the number of TCH drops due to Cause 6 (Too long MS-BS distance).

• MC928f (type 110): NB_TCH_DROP_CAUSE_TOO_SHORT_MS_BS_DISTANCE that indicates the number of TCH drops due to Cause 22 (Too short MS-BS distance).

• MC928g (type 110): NB_TCH_DROP_CAUSE_TOO_HIGH_INTERFERENCE_UPLINK that indicates the Number of TCH drops due to Cause 15 (Too high interference level on the uplink).

• MC928h (type 110): NB_TCH_DROP_CAUSE_TOO_HIGH_INTERFERENCE_DOWNLINK that indicates the number of TCH drops due to Cause 16 (Too high interference level on the downlink).

• MC928i (type 110): NB_TCH_DROP_OTHER_CAUSES that indicates the Number of TCH drops due to other causes than Cause 2 (Too low quality in UL), Cause 3 (Too low level in UL), Cause 4 (Too low quality on the downlink), Cause 5 (Too low level in DL), Cause 6 (Too long MS-BS distance), Cause 15 (Too high interference level on the uplink), Cause 16 (Too high interference level on the downlink), Cause 22 (Too short MS-BS distance).

2.3.5. IMPROVEMENT 5: AMR-WB IN GMSK

This feature brings improved voice quality in terms of increased voice naturalness for the audio bandwidth extended to 7 kHz.

The introduction of this feature leads to introduction of thirteen new counters. Six new counters were introduced in RMS family and seven counters were introduced in MC93x familiy (where x = 1….7) :

• RMS41a (type 31): AMR_WB_GMSK_FR_UL_BAD that indicates the Table of 3 results. Each cell (i) of the table contains: number of FR AMR WB GMSK UL bad speech frames.

• RMS41b (type 31): MAX_AMR_WB_GMSK_FR_UL_BAD that indicates the Greatest values of the Vi in RM41a. • RMS42a (type 31): AMR_WB_GMSK _FR_UL_RXLEV_UL that indicates the Table of 3x10 results. Each cell (i,k)

of the table contains: number of correct UL speech frames using FR AMR WB GMSK codec k for which UL RXLEV is reported in level band i.

3.1.1.1. BSS Counter types

OMC-R indicators are established from performance counters provided by the BSS. Performance Management is a BSS facility, which provides measurements and statistics on various traffic events and resource usage in the BSS. The BSS has 30 types of counters organised into three classes: � Cumulative counters (C1): All events are counted when specific events occur. They are reset when a new collection

period is started. They indicate only the number of events that occurred during the period covered by the last report. � Statistical counters (C2): Status inspection is executed every 20 seconds. Statistical data is collected relating to the status

of a specific resource. The counters can be rounded to closest integer or truncated to lower integer, please refer to document ref. [2] for details.

� Event observation (C3): An observation supplies detailed information on a system event. For example, the channel seizure

time for an SDCCH is an observation counter. It gives the time and date when the SDCCH is seized. For the present document, QoS monitoring indicators are derived from counter types 26, 27, 29, 32, 110 and 180: therefore from classes C1 and C2. The mechanisms of Performance Management counters as well as counters' availability and definition are detailed in document [1] "BSS/OMC-R O&M Reference Guide" The list of validated counters is given in document [1].

3.1.1.2. Measurement Activation at OMC-R

As usual, the permanent activation of types 110 and 180 shall be recommended with BSS B10.

3.1.2. CLASSIFICATION AND NAMING CONVENTIONS

3.1.2.1. Classification

The present chapter defines standard indicators that can be used to follow behaviour and Quality of any kind of GSM networks, equipped with Alcatel BSS in Release B10.

OMC-R Indicators can be divided into 4 basic categories: • Traffic Load and Traffic Model

• Quality of service (efficiency of transactions)

• Handover statistics

• Resource availability

Upon these are defined indicators related to densification techniques (as Directed Retry, Concentric Cells, Micro Cells, Multiband...). The following diagram details this classification of GSM indicators:

Upon these categories can be extracted the Global BSS indicators. They will be marked with symbol "(G)" after their name.

3.1.2.2. Naming conventions

In the following description, the symbol "Σcell" means the sum for a subset of cells:

- the cell itself for a cell level indicator - sum of the cells of a BSC for a BSS level indicator - sum of all cells of network for a network level indicator

In the same way: • the symbol "ΣTRX" means the sum for a subset of TRXs:

- all TRXs of a cell for a cell level indicator - all TRXs of the cells of a BSC for a BSS level indicator - all TRXs of the cells of network for a network level indicator

• the symbol "ΣTS" means the sum for a subset of Time Slots of same type (SDCCH, TCH, ...)

- all timeslots of a TRX for a TRX level indicator - all timeslots of a cell for a cell level indicator - all timeslots of the cells of a BSC for a BSS level indicator - all timeslots of all cells of network for a network level indicator

For the Microcellular indicators, the formula convention is the following: Σ x-> cell micro (Cxx) means: sum of values of counters Cxx from microcell x to any other microcell.

3.1.2.3. QOS Description template

GSM indicator will be described as follows: INDICATOR

3.1.2.4. Formalism of telecom procedures

The same formalism is used for all telecom procedures (immediate assignment, normal assignment, handover, directed retry), for consistency purposes.

“Telecom procedure” -ATTEMPT

“Telecom procedure” -SUCCESS

“Telecom procedure” -whose channel isALLOCATED in BSC

channel activation failure

assignment/HO execution failure

PREPARATION phase

EXECUTION phase

- radio link failure- BSS problem- NSS problem

“Telecom procedure” -REQUEST

- BSS problem- NSS problem

- congestion

Based on this formalism, the following general indicators formulas are deducted:

Success Rate = (Success) / (Request)

Efficiency Rate = (Success) / (Allocated)

Unsuccess Rate = (Preparation & Execution Failures) / (Request)

Failure Rate = (Failure) / (Request)




3.2. TRAFFIC LOAD AND TRAFFIC MODEL INDICATORS

This set of indicators provides users with:

- definition of number of transactions attempts (MOC, MTC, Handover, ...), - traffic (in Erlang) computation for a cell, a BSC - load on traffic and signalling channels to evaluate cell and BSC channel's dimensioning

Notes about Control channels load computation Denominator for RACH, AGCH, PCH and PAGCH load It is the maximum number of bursts (respectively RACH, AGCH, PCH and PAGCH=PCH+CCCH) that can be sent during one hour on BCCH/CCCH multiframes, according to channel configuration, it is computed with following rules:

- 3600 = 3600 seconds - 0.235 = 235ms / 1000ms = one multiframe duration, 1/0.235 = number of multiframes in 1 second. - N1, N2, N3: number of bursts RACH, AGCH and PCH respectively in one CCCH multiframe :

- N1 defined as: - 27 if cell is configured in BCCH combined mode, - 51 in one CCCH not combined mode, - 2*51 in two CCCH not combined mode (Multiple CCCH feature activated). - N2 defined as: - BS_AGBLK_RES for CCCH blocks in combined BCCH mode or not combined BCCH mode - BS_AGBLK_RES*2 in Two CCCH not combined mode (Multiple CCCH feature activated) - configured at OMC-R, typically 1 in combined BCCH mode, 4 in uncombined BCCH mode and 8 in

two CCCH not combined BCCH mode - N3 defined as: - 3 CCCH blocks in combined BCCH mode, - 9 in not combined BCCH mode, - 18 in Two CCCH not combined mode (Multiple CCCH feature activated). - N4 = average number of mobile identity sent within one PAGING REQUEST (Type 3) message. Its

value depends on mobile identification mode in paging used over the network: by IMSI or TMSI. Typical values are :

N4 = 3 if Paging is performed using TMSI (used on NPO formula) N4 = 1.5 if Paging is performed using IMSI This parameter is configured at NSS level.

Cell nominal load = maximum traffic (TCH Erlang) that can be handled by the cell, using Erlang law B with default TCH blocking rate (typically 2%). Application example with cell4 TRX, 30 TCH.

- Maximum traffic = 21 Erl (at 2% blocking rate) - Actual Traffic (TCH) = 14 Erl - Actual AGCH Load = 45% - AGCH Load at cell nominal load = 45% *21 / 14 = 67.5%

=> re-dimensioning of CCCH is required

INDICATOR

(G) CELL QUALITY FACTOR ABSOLUTE

DEFINITION Indicator summarising the cell behaviour and allowing the operator to sort out cell for investigation. This indicator is based on failure events. For each part of the indicator, two thresholds are used: Topt and TQoS.TQoS is the QoS warning threshold. Topt + TQoS is the optimal value that should be achieved. Each part has a weighting factor (WF) according to the impact on subscriber’s point of view.

FORMULA ((1 – SDCCH CONGESTION RATE) - TQoS)/ Topt * WF + (CALL SETUP SUCCESS RATE - TQoS)/ Topt *WF + ((1 – CALL DROP RATE - TQoS)/ Topt * WF + (OUTGOING HO SUCCESS RATE - TQoS)/ Topt * WF + ((1 – HO QUALITY RATE - TQoS)/ Topt * WF

3.4. HANDOVER STATISTICS

This set of indicators provides users with detailed indicator's definition dedicated to handover

- split of Handover causes per cell and per couple of cells, - definition of outgoing HO success/detailed failure rate (preparation, realisation), - definition of incoming HO success/detailed failure rate (preparation, realisation), - HO statistics per couple of cell.

Analysis of HO indicators will help for identification of neighbouring problems (definition and parameters), and interference or coverage problems, for fine tuning activity.

3.8.3.2. HO statistics

In a multilayer / multiband network, it is very interesting to get handover statistics from a given cell to all cells of a given cell type (or layer) or per couple of cell types. This will be done using counters Type 180 for incoming handovers or/and using A-Interface traces, with the COMPASS tool using the menu AGLAE statistics giving for example handover results per couple of cells or per cell types. The following layers are interesting

- for multiband : 1800, 900 - for microcellular : umbrella, micro, single.

These cell types can be extracted from OMC-R configuration. Moreover, in multiband/multilayer environment combinations of multiband and multilayer cell types shall be used for example: micro 1800, umbrella 900, umbrella 1800… Besides, thanks to the feature "Multiband cell" introduced in B6.2, it is possible to have two layers in the same cell.

3.8.4. INDICATORS FOR MULTIBAND

This part in comparison with the last one is dedicated to multiband network and multiband cells only. N.B: All statistics related to dual band must be correlated to dual band mobiles penetration rate: SDCCH TRAFFIC DUAL BAND MS (see 3.2.1.3 part). Indeed, OMC-R counters do not allow making a split of statistics between single and dual band mobiles. For example, a low occupation of 1800 layer does not mean that it is not efficiently used, if dual band MS penetration rate is insignificant.

3.8.4.1. General QoS

With such multiband/multilayer network, it is interesting to collect QoS statistics (especially congestion, call drop) that are described in section 3.3, on a per layer basis, and therefore to consolidate results accordingly. As it was already noted in the last part, the following layers are interesting for multiband: 1800, 900. These cell types can be extracted from OMC-R configuration. Moreover, in multiband/multilayer environment combinations of multiband and multilayer cell types shall be used for example: micro 1800, umbrella 900, umbrella 1800… Moreover: - thanks to the feature “Multiband cell”, it is possible to have 2 layers in the same cell - thanks to the creation of new counters per TRX, it is possible to compute QoS statistics for multiband cells:

• HO statistics per zone: - Efficiency and success rate of outgoing handovers - Rate of outgoing handover failures due to radio problems, BSS problems or failures with reversion to old

channel - Rate of incoming handover successes - Rate of incoming internal directed retries.

• Normal assignment statistics per zone - Rate of RTCH seizures during the normal assignment procedure - Number of RTCH seizures failed due to radio problems.

• general QoS statistics per zone - drops due to radio problems - drops due to HO problems - drops due to BSS remote transcoder failures.

See descriptions of indicators in section 3.3.

3.10.1. EM EXPOSURE AND COMPLIANCE BOUNDARY

Base Station antennas emit electromagnetic field in their neighbourhood. People living close to the antennas are sometimes concerned about the real level of exposure to RF fields. A compliance boundary is defined around the antenna(s) to comply with exposure limits to electromagnetic fields. The higher is the emission power of the antenna, the wider shall be the zone. A power exceeding means that outside the zone the EM level is higher than the reference level.

APPENDIX A: GSM INDICATORS NAMING RULES FOR REFERE NCE NAMES Several namings were up to now available for QoS indicators:

- Methods document naming, - NPO indicators.

In order to initiate convergence of all these naming, a unique indicator name has been defined, that will be present in methods and tools and will be a key for databases. This name is:

- Split in several fields that can be mandatory or optional.

Field Value Number of digits Family Mandatory 2 Procedure Optional 2 Prefix Optional 1 Type Optional 2 Sub-type Optional 1 Joker Optional 1 Unit Mandatory 1

Family

QoS indicators have been split in 8 families which gives the first 2 digits of the reference name:

APPENDIX B: GLOBAL VIEW OF NPO INDICATORS – DIAGRAM FORMS

In this annex, all the NPO indicators for GSM part are listed under graphical views. All these graphs present the "philosophy" used for the creation of NPO indicators, which corresponds to the main steps of the telecom procedures. Most of these diagrams are named according to NPO families. The indicators in bold characters are "top indicators". It means that the NPO user can find them in the "Main" NPO family. The indicators available also per TRX are marked with a star.
