1 Call Setup Success Rate (CSSR)

Call Setup Success Rate is the percentage of Successful TCH Seizures out of total Call Setup Attempts. Congestion on Traffic/Signalling channels as well as abnormal releases of signalling channels during call establishment reduce the call set-up success rate. Recommended Calculation Formula

Successful Call Setup TCH Seizures (ASSIGNMENT COMPLETE)

Total Call Setup Requests (CHANNEL REQUIRED or ESTABLISH INDIC) CSSR=

Notes: Messages pertaining to Voice Calls only need to be considered for evaluation of CSSR (SMS , Loc Update, IMSI Detach related requests as distinguished from Channel Required or Establish Indication messages need to be excluded). In case Total Call Setup Requests (i.e. denominator) is calculated from ESTABLISH INDICATION message, the formula needs to be multiplied with the term ‘SDCCH Allocation Success Rate’ due to the fact that ESTABLISH INDICATION messages is only received once SDCCH is successfully allocated. ‘SDCCH Alloc Success Rate’ is defined as the ratio of Successful SDCCH Allocations to the Total SDCCH Allocation Requests. Huawei CSSR Formula [ Call failures caused by MSC no response, CM REQ REJ, CREF, number error, called party unreachable, BSS disconnection, or non-BSS reasons, such as the MSC sends cancel messages, should not be considered. Only the BSS effect against the CSSR should be noted. ] CSSR = Immediate assign success rate *(1- SDCCH drop rate) * (Assignment success rate) = (CA303J/ CA300J)*(1- CM30/ K3003)* (K3013A/ K3010A)* 100% Immediate assign success rate = CA303J:Call Setup Indications (Circuit Service) [1278075462]/ CA300J:Channel Requests (Circuit Service) [1278075461]

Meaning:

In the immediate assignment procedure, an MS reports a FIRST SABM frame to the BTS on the seized signaling channel (SDCCH, TCHF, or TCHH). Through this frame, the MS notifies the BTS that the radio link layer has entered the multiframe link setup state. The BTS returns a UA frame to the MS and sends the BSC an EST IND message to notify the BSC that the link is established on the Um interface.

After link setup on the air interface, counter A3039J: SDCCH Seizures for Speech Service is measured for speed service.

In the immediate assignment procedure, the BSC sends an IMM ASS CMD message to an MS and triggers a timer. If no EST IND message is received within scheduled time (10 seconds by default), the BSC measures the counters related to the timeout of call setup indications. Trigger:

As shown in Figure 1-1 (C), the measurement related to call setup indications is triggered when the BSC receives an EST IND message from the BTS where the target cell is located. This measurement is based on the channel type, the value of the service request message, and the number of seized SDCCHs for speech service.

Meaning:

After an MS occupies a channel, the BTS sends an ERR IND message to the BSC because of radio link errors. Call drops occur on the Um interface. When receiving the ERR IND message with a cause value of timer T200 expired (N200+1) times (0x01), unsolicited DM response, multiple frame established state (0x05), or sequence error (0x07) in it, the BSC measures the call drop counters related to ERR IND. The measurement is based on the channel type (SDCCH, TCHF, or TCHH), service type (signaling or traffic), and cause value. Trigger:

The measurement of call drops is triggered when a call drop occurs. The measurement of successful connections is triggered when the called party answers. K3003:Successful SDCCH Seizures [1278087421]: Formula: K3003:Successful SDCCH Seizures [1278087421] =

Meaning:

This counter measures the number of TCH (traffic channel) seizure requests received by the BSC from the MSC.

In the immediate assignment procedure, the BSS assigns a signaling channel to an MS. After the RR connection between the MS and the BSS is established, the MS establishes the MM and the CC connections with the MSC through the signaling channel. Based on the CC connection request from the MS, the MSC assigns terrestrial resources to the MS and specifies available channel types in an ASS REQ message. Trigger:

Meaning:

After an MS occupies a channel, the BTS sends an ERR IND message to the BSC because of radio link errors. Call drops occur on the Um interface. When receiving the ERR IND message with a cause value of timer T200 expired (N200+1) times (0x01), unsolicited DM response, multiple frame established state (0x05), or sequence error (0x07) in it, the BSC measures the call drop counters related to ERR IND. The measurement is based on the channel type (SDCCH, TCHF, or TCHH), service type (signaling or traffic), and cause value.

After an MS occupies a channel, the BTS sends a CONN FAIL IND message to the BSC because of radio link errors or hardware failure. Call drops occur on the Um interface. When receiving the CONN FAIL IND message with a cause value of radio link failure (0x01), handover access failure (0x02), OM intervention (0x07), or radio resource not available (0x21) in it, the BSC measures the call drop counters related to CONN FAIL IND on the basis of the channel type (SDCCH, TCHF, or TCHH), service type (signaling or traffic), and cause value.

In multiframe link setup status, the BTS sends a REL IND message to the BSC after receiving the DISC frame from an MS. Call drops occur on the Um interface. The BSC measures the call drop counters related to REL IND on the basis of the channel type (SDCCH, TCHF, or TCHH), service type (signaling or traffic), and cause value.

After an MS occupies an SDCCH, it sends a measurement report to the network every 470 ms. After an MS occupies a TCH, it sends a measurement report to the network every 480 ms. If the BSC does not receive any measurement report within scheduled time (five minutes by default), call drops occur on the Um interface. The BSC measures the call drop counters related to no measurement reports based on the channel type (SDCCH, TCHF, or TCHH) and the service type (signaling or traffic).


2007-11-2 10

After an MS occupies a channel, the BTS sends a CONN FAIL IND message to the BSC because of radio link connection failure. Call drops occur on the Um interface. When receiving the CONN FAIL IND message with a cause equipment failure (0x20) or terrestrial channel failure (0x22), the BSC measures the call drop counters related to hardware failure on the basis of the channel type (SDCCH, TCHF, or TCHH), service type (signaling or traffic), and cause value.

After an MS occupies a channel, the BSC measures the call drop counters related to equipment failure on the basis of the channel type (SDCCH, TCHF, or TCHH) and the service type (signaling or traffic) if a release procedure is initiated because of BSC internal errors.

After an MS occupies a channel, a forced handover is initiated but failed. If the release procedure is required, the BSC measures the call drop counters related to the forced handover based on the channel type (SDCCH, TCHF, or TCHH) and the service type (signaling or traffic).

After an MS occupies a channel, a release procedure is initiated if the resource check fails. The BSC measures the call drop counters related to the resource check based on the channel type (SDCCH, TCHF, or TCHH) and the service type (signaling or traffic).

After a call is established, a conversation begins if the called party answers. If a call drop occurs for a certain reason, the BSC measures the related call drop counters after a conversation begins based on the channel type (TCHF or TCHH).

After a call is established, the BSC receives the CONN message from the called MS and the CONN ACK message from the calling MS if the called party answers. The BSC measures the counters related to successful connections based on the channel type (TCHF or TCHH).

After an MS occupies a channel, the BSC measures the counters related to clear requests sent on the A interface on the basis of the channel type (SDCCH, TCHF, or TCHH), service type (signaling or traffic), or status (stable or HO) when the BSC sends a CLR REQ message to the MSC.

Trigger: The measurement of call drops is triggered when a call drop occurs. The measurement of

successful connections is triggered when the called party answers. CH303:Successful Internal Intra-Cell Handovers [1278077482] Formula: CH303: Successful Internal Intra-Cell Handovers=

5 Rx-Qual Poor

Rx Qual Poor is defined as the received signal having a BER of worse than or equal to the range 3.2% to 6.4% (or equivalently greater than or equal to value of 5 on conventional 0-7 scale for Rx Qual) as evaluated from a complete SACCH block. Threshold value indicates the maximum limit for the percentage of samples lying within the above defined signal quality range. Huawei RX-QUAL Poor formula： There are two definitions of RX-QUAL Poor. One is depend on drive test and another one is depend on traffic statistics. Drive Test RX-QUAL Poor (downlink)= sample of Rx_Qual 5~7/ sample of Rx-Qual 0-7 *100% Others: below formula is reference only. RX-QUAL Poor (5 class) (downlink)= sample of Rx_Qual 5/ sample of Rx-Qual 0-7 *100% RX-QUAL Poor (6 class) (downlink)= sample of Rx_Qual 6/ sample of Rx-Qual 0-7 *100% RX-QUAL Poor (7 class) (downlink)= sample of Rx_Qual 7/ sample of Rx-Qual 0-7 *100% Traffic Statistics RX-QUAL Poor (downlink) = (CS415B + CS416B + CS417B + CS415D + CS416D + CS417D) / (CS410B+CS411B+CS412B+CS413B+CS414B+CS415B+CS416B+CS417B + CS410D+CS411D+CS412D + CS413D+CS414D+CS415D+CS416D+CS417D) *100%

6 Handover distribution – PBGT

Handover distribution – PBGT (cell level) is the percentage of successful outgoing inter-cell handovers with the cause ‘Power Budget’ out of the total successful outgoing inter-cell handovers triggered in the cell.


2007-11-2 22

Threshold value indicates the minimum limit for the percentage of successful handovers with the cause power budget. Note An outgoing inter-cell handover with the cause ‘power budget’ occurs when a neighbor cell gets the status of a better server than the existing cell. Huawei Handover distribution – PBGT formula： Handover distribution – PBGT = (H310F:Outgoing Internal Inter-Cell Handover Requests (Better Cell) [1278079496] – H3122F:Failed Outgoing Internal Inter-Cell Handovers (Better Cell) [1278079520] +

H330F:Outgoing External Inter-Cell Handover Requests (Better Cell) [1278081458] – H3322F:Failed Outgoing External Inter-Cell Handovers (Better Cell) [1278081482]) /

(CH313:Successful Outgoing Internal Inter-Cell Handover [1278079528] + CH333:Successful Outgoing External Inter-Cell Handovers [1278081557]) *100% Outgoing Internal Inter-Cell Handover Requests (Excluding Directed Retry)

Meaning: The BSC uses the handover algorithm to decide whether a handover is required or not based on the measurement reports. If a handover is required and the source cell (current cell) and the target cell are two cells controlled by one BSC, the BSC initiates an internal inter-cell handover.

The counter measures the number of outgoing internal inter-cell handover requests initiated by the BSC. The measurement is based on the handover cause.

The handover causes consist of the following:

Uplink quality

Downlink quality

Uplink strength

Downlink strength

Timing advance

Better cell

Load

Rapid level drop

MSC intervention

OM intervention

Other causes

Trigger: As shown in Figure 6-1 (A), the measurement is triggered when the BSC decides to initiate an outgoing internal inter-cell handover based on measurement

7 Handover distribution – RxQual DL

Handover distribution – RxQual DL (cell level) is the percentage of outgoing inter-cell handovers triggered with the cause ‘downlink signal quality’ out of the total outgoing inter-cell handovers triggered in the cell.


2007-11-2 28

Threshold value indicates the maximum limit for the percentage of handovers to be triggered with the cause downlink signal quality. Note An outgoing inter-cell handover with the cause ‘downlink signal quality’ is triggered when the downlink signal quality falls below a preset threshold. Huawei Handover distribution – RxQual DL Formula: Handover distribution - RxQual DL = (H310B: Outgoing Internal Inter-Cell Handover Requests(Downlink Quality)[1278079492] + H330B: Outgoing External Inter-Cell Handover Requests (Downlink Quality) [1278081454]) / (CH310: Outgoing Internal Inter-Cell Handover Requests [1278079527] + CH330: Outgoing External Inter-Cell Handover Requests [1278081556]) *100%

8 Grade of Service- SDCCH (GoS-SDCCH)

Grade of Service on SDCCH (cell level) is the percentage of SDCCH Allocation Request Failures due to lack of SDCCH Resources out of Total SDCCH Allocation Requests.
