Counter Name : NB_TCH_DROP_HO_PREP_EXEC_FAIL_BSS_PB Counter Integer SFD reference : No reference. Length 4 Data collection Cumulative Measured unit: number Release Measured object Package B8 Common cell 0 B9 Common cell 1 Technology: GSM Sub domain-1: Handover Sub domain-2: TCH Domain: Quality of Service Sub domain-3: Failure Counter definition: Number of TCH (in HR or FR usage) drops due to BSS problem during any TCH handover preparation and execution phases. This counter is incremented on the cell on which the problem occurs(In the case of internal inter-cell handovers, it is not incremented on both serving and target cell). For problems that are not related to a specific cell, the counter related to the serving cell will be incremented. It may happen that several causes of failures mentioned below are detected consecutively. In that case, the counter will only be incremented once, as soon as the handover procedure fails.

Trigger condition: 1) Whenever the BSC receives on Abis interface from the target cell negative acknowledgment to the TCH channel activation involved in the handover procedure. 2) Whenever the timer supervising the Channel Activation procedure (T9103) expires on the target cell during activation of a TCH channel involved in the handover procedure. 3) Whenever an 48.058 ERROR REPORT message with a cause value of "O&M intervention" is received on Abis interface from either the serving or the target cell during the external or internal inter-cell handover procedure and leads to a transaction failure. 4) Whenever an 48.058 ERROR REPORT message with a cause value of "O&M intervention" is received on Abis interface on either the old or the new channel during the internal intra-cell handover procedure and leads to a transaction failure. 5) Whenever an 48.058 ERROR REPORT message on SAPI 0 with a cause value of "message sequence error" is received on Abis interface from the serving cell between the sending of the 48.058 CHANNEL ACTIVATION message and the reception of the 48.058 CHANNEL ACTIVATION ACKNOWLEDGMENT during the internal inter-cell TCH handover and leads to a transaction failure. 6) Whenever an 48.058 ERROR REPORT message on SAPI 0 with a cause value of "message sequence error" is received on Abis interface on the old channel between the sending of the 48.058 CHANNEL ACTIVATION message and the reception of the 48.058 CHANNEL ACTIVATION ACKNOWLEDGE during the internal intra-cell TCH handover and leads to a transaction failure. 7) Whenever a LAPD failure related to either serving or target cell is reported to the Layer 3 of the BSC (for an RSL supporting a TCH transaction for handover purpose) and leads to a transaction failure. 8) Whenever an TCH handover abortion is initiated by the BSS O&M FAULT MANAGEMENT application part or by the BSS TELECOM application part as the result of a system defense action which may be due to BSS equipment failures external to the BSC (e.g. RSL failure or CU recovery failure), or due to BSC internal hardware problems (e.g. TCU failure or DTC failure) or due to BSC internal software problems (e.g. inconsistencies detected between software modules or lack of software resources (memory, timer reference, file reference...) or communication problems between different processor boards). 9) Whenever a 48.058 CONNECTION FAILURE INDICATION message with a cause value of "remote transcoder failure" is received on Abis interface from the old channel between the sending of the 48.058 CHANNEL ACTIVATION message and the reception of the 48.058 CHANNEL ACTIVATION ACKNOWLEDGE during an internal intra-cell or inter-cellTCH handover procedure and leads to a transaction failure. Notes :

1. TCH handover failures which are due to O&M operator actions on BTS or BSC should not be counted. Indeed, in case of numerous failures due to O&M commands, this counter will overestimate failures which are due to problems which are internal to the BSS. However, due to the current implementation which does not allow to be aware of the origin of the failure, O&M operator actions will also be counted.

Remark: If an internal directed retry is attempted and failed while T11/T11_forced is running, the request is un-holded and the BSC waits for the expiry of the relevant timer. Consequently, this counter must not be incremented upon the failure of an internal directed retry.

At the expiry of the accumulation period, all samples are averaged (i.e. summed and divided by the number of samples). The averaged value is rounded up or down to the nearest value with an accuracy of 0.1. A TCH radio timeslot is considered as busy during the time it is allocated to a given MS for TCH traffic (in HR or FR usage). A dynamic SDCCH/8 timeslot allocated as TCH is considered as busy during the time it is allocated to a given MS for TCH traffic. Note 1: the counter value that is indicated in the ASCII file (which can be obtained via the OBSYNT interface) is an integer value (i.e. it is as if the BSC multiplies by 10 the average).

A MS is considered as multiband if it supports: - the P-GSM (or E-GSM or R-GSM) and the DCS1800 bands if the PLMN_FREQUENCY_BANDS parameter is set to "GSM900 and DCS1800 bands", or, - the GSM850 and the DCS1800 bands if the PLMN_FREQUENCY_BANDS parameter is set to "GSM850 and DCS1800 bands", or, - the GSM850 and the DCS1900 bands if the PLMN_FREQUENCY_BANDS parameter is set to "GSM850 and DCS1900 bands", or, - the P-GSM (or E-GSM or R-GSM) and the DCS1900 bands if the PLMN_FREQUENCY_BANDS parameter is set to "GSM900 and DCS1900 bands".

Trigger condition: The counter cumulates, over the Accumulation Period, per radio timeslot, all unit times during which the TCH HR channel (or the dynamic SDCCH/8 timeslot) is busy. For each channel allocation: 1) The counter starts being incremented after the sending of the 48.058 CHANNEL ACTIVATION message concerning : - an half rate TCH channel (or a dynamic SDCC/8 timeslot) mapped either on the upper half or the lower half of the related TRX timeslot. - a mobile which has sent a 44.018 CLASSMARK CHANGE message with a "Mobile Station Classmark 3" Information Element field specifying that it is a multiband MS. the MS supports: - the P-GSM (or E-GSM or R-GSM) and the DCS1800 bands if the PLMN_FREQUENCY_BANDS parameter is set to "GSM900 and DCS1800 bands", or, - the GSM850 and the DCS1800 bands if the PLMN_FREQUENCY_BANDS parameter is set to "GSM850 and DCS1800 bands", or, - the GSM850 and the DCS1900 bands if the PLMN_FREQUENCY_BANDS parameter is set to "GSM850 and DCS1900 bands", or, - the P-GSM (or E-GSM or R-GSM) and the DCS1900 bands if the PLMN_FREQUENCY_BANDS parameter is set to "GSM900 and DCS1900 bands". 2) The counter stops being incremented when no HR sub-channel (or the dynamic SDCCH/8 timeslot) concerning a multiband mobile is active anymore on the related TRX channel. This is after the reception of a 48.058 RF CHANNEL RELEASE ACKNOWLEDGE message or the expiry of timer T_RCR_ACK twice (after the sending of the 48.058 RF CHANNEL RELEASE message) or the BSC internal radio resource release due to any BSS problem, concerning the last HR TCH channel (or the dynamic SDCCH/8 timeslot) related to a multiband mobile.

Type definition: This measurement type provides observations on incoming external SDCCH or TCH (in HR or FR usage) handover. An observation is composed of a set of records, each record being related to a single channel seizure within the observed cell. A record is a consistent structure of data made up of several fields (called DER) providing information about the radio configuration and about specific events that are cumulated. Not all channel seizures are observed in the cell, but one per sample_rate value. For an observed channel, the recording of data starts in the BSC as soon as 08.08HANDOVER REQUEST is sent on A interface by the BSC.

Length 4 Data collection Cumulative Measured unit: number Release Measured object Package B8 Common cell 0 B9 Common cell 1 Technology: GSM Sub domain-1: Handover Sub domain-2: TCH Domain: Quality of Service Sub domain-3: Failure Counter definition: Number of TCH (in HR or FR usage) drops due to BSS problem during any TCH handover preparation and execution phases. This counter is incremented on the cell on which the problem occurs(In the case of internal inter-cell handovers, it is not incremented on both serving and target cell). For problems that are not related to a specific cell, the counter related to the serving cell will be incremented. It may happen that several causes of failures mentioned below are detected consecutively. In that case, the counter will only be incremented once, as soon as the handover procedure fails.

Trigger condition: 1) Whenever the BSC receives on Abis interface from the target cell negative acknowledgment to the TCH channel activation involved in the handover procedure. 2) Whenever the timer supervising the Channel Activation procedure (T9103) expires on the target cell during activation of a TCH channel involved in the handover procedure. 3) Whenever an 48.058 ERROR REPORT message with a cause value of "O&M intervention" is received on Abis interface from either the serving or the target cell during the external or internal inter-cell handover procedure and leads to a transaction failure. 4) Whenever an 48.058 ERROR REPORT message with a cause value of "O&M intervention" is received on Abis interface on either the old or the new channel during the internal intra-cell handover procedure and leads to a transaction failure. 5) Whenever an 48.058 ERROR REPORT message on SAPI 0 with a cause value of "message sequence error" is received on Abis interface from the serving cell between the sending of the 48.058 CHANNEL ACTIVATION message and the reception of the 48.058 CHANNEL ACTIVATION ACKNOWLEDGMENT during the internal inter-cell TCH handover and leads to a transaction failure. 6) Whenever an 48.058 ERROR REPORT message on SAPI 0 with a cause value of "message sequence error" is received on Abis interface on the old channel between the sending of the 48.058 CHANNEL ACTIVATION message and the reception of the 48.058 CHANNEL ACTIVATION ACKNOWLEDGE during the internal intra-cell TCH handover and leads to a transaction failure. 7) Whenever a LAPD failure related to either serving or target cell is reported to the Layer 3 of the BSC (for an RSL supporting a TCH transaction for handover purpose) and leads to a transaction failure. 8) Whenever an TCH handover abortion is initiated by the BSS O&M FAULT MANAGEMENT application part or by the BSS TELECOM application part as the result of a system defense action which may be due to BSS equipment failures external to the BSC (e.g. RSL failure or CU recovery failure), or due to BSC internal hardware problems (e.g. TCU failure or DTC failure) or due to BSC internal software problems (e.g. inconsistencies detected between software modules or lack of software resources (memory, timer reference, file reference...) or communication problems between different processor boards). 9) Whenever a 48.058 CONNECTION FAILURE INDICATION message with a cause value of "remote transcoder failure" is received on Abis interface from the old channel between the sending of the 48.058 CHANNEL ACTIVATION message and the reception of the 48.058 CHANNEL ACTIVATION ACKNOWLEDGE during an internal intra-cell or inter-cellTCH handover procedure and leads to a transaction failure. Notes :

1. TCH handover failures which are due to O&M operator actions on BTS or BSC should not be counted. Indeed, in case of numerous failures due to O&M commands, this counter will overestimate failures which are due to problems which are internal to the BSS. However, due to the current implementation which does not allow to be aware of the origin of the failure, O&M operator actions will also be counted.

Length 2 Data collection Status Inspection (polling=10s) Measured unit: number Release Measured object Package B8 Common cell 0 B9 Common cell 1 Technology: GSM Sub domain-1: Channel Sub domain-2: TCH Domain: Resource Availability & Usage Sub domain-3: Usage Counter definition: Average number of busy TCH radio timeslot (in FR or HR usage) and busy dynamic SDCCH/8 radio timeslot allocated as TCH. Trigger condition: The BSC takes periodically a sample of the number of busy TCH radio timeslots and busy dynamic SDCCH/8 radio timeslots allocated as TCH. The sampling period is set to the value indicated in the Status Inspection field. At the expiry of the accumulation period, all samples are averaged (i.e. summed and divided by the number of samples). The averaged value is rounded up or down to the nearest value with an accuracy of 0.1. A TCH radio timeslot is considered as busy during the time it is allocated to a given MS for TCH traffic (in HR or FR usage). A dynamic SDCCH/8 timeslot allocated as TCH is considered as busy during the time it is allocated to a given MS for TCH traffic. Note 1: the counter value that is indicated in the ASCII file (which can be obtained via the OBSYNT interface) is an integer value (i.e. it is as if the BSC multiplies by 10 the average). The reported value shall then be divided by 10 afterwards so that the value that is displayed to the end-user is the correct one. Note 2: This counter does not take into account the PDCH radio timeslots allocated to the MFS.

Case: 48.008ASSIGNMENT REQUEST on TCH (in HR or FR usage) is received when no TCH is available in the cell. The request is rejected (by 48.008ASSIGNMENT FAILURE, cause: "no radio resource available"), because the queuing procedure is either: 1) disabled within the BSC (i.e. (T11=0 and QUEUE_ANYWAY=0), OR (T11_forced=0 and QUEUE_ANYWAY=1)), or 2) enabled within the BSC, i.e. T11 <> 0, but not requested by the MSC when QUEUE_ANYWAY=0.

Trigger condition: The counter is incremented upon the sending of 48.008ASSIGNMENT FAILURE (cause: "no radio resource available") for a TCH channel because no TCH is available and either the queing is disabled in the BSC (T11=0 and QUEUE_ANYWAY=0, or T11_forced=0 and QUEUE_ANYWAY=1), or the queing is enabled, QUEUE_ANYWAY=0, and the MSC does not request a queuing.

Remark: If an internal directed retry is attempted and failed while T11/T11_forced is running, the request is un-holded and the BSC waits for the expiry of the relevant timer. Consequently, this counter must not be incremented upon the failure of an internal directed retry.

Trigger condition: The counter is incremented upon the sending of 48.008 CLEAR REQUEST (cause : "no radio resource available") -following the expiry of T11 or T11 forced for a queued TCH normal assignment. Note: The HMI name of the parameter QUEUE_ANYWAY is "FORCED_QUEUING".

Remark: As soon as an internal directed retry is attempted, the request is blocked within the BSC and cannot be dequeued by a higher priority request.
