Measurement point: if BSS fails to respond to ASSIGNMENT COMPLETE message to MSC due to some reason after receiving ASSIGNMENT REQUEST message, this item is measured and BSS responds ASSIGNMENT FAILURE message to MSC simultaneously. Figure 15 (in Part A) Assignment implementation process indicates the measurement point. Successful immediate assignments [2186]: Description: In the immediate assignment procedure, after successfully seizing a channel (SDCCH or TCH) allocated by BSC for transferring signaling, MS reports a SABM frame on this channel to BTS, indicating the establishment of a radio link layer connection in the multi-frame mode. BTS returns a UA frame to MS, and sends an ESTABLISH INDICATION message to BSC, notifying it to establish a normal Um interface connection. Measurement point: This item is measured when BSC receives an ESTABLISH INDICATION message from BTS in the immediate assignment procedure.

Full Rate Traffic

Huawei Traffic Statis. Item : TCHF traffic volume (excluding very early assignment) [23302] Description: This item provides the traffic volume on Full rate TCHs (excluding those seized in very early assignment procedure), i.e. the ratio of the duration of MS seizing Full rate TCH to measurement period. The duration of MS seizing Full rate TCH is obtained by multiplying the number of MRs reported by MS on Full rate TCH with 0.48 seconds (period for reporting MRs).

Measurement point: 1) This item is measured if there is no available TCH when the MS requests channel from BSC in very early TCH assignment procedure. 2) In very early TCH assignment procedure, after BSC allocates a TCH, it sends a CHANNEL ACTIVATION message to the BTS to activate this channel.

Measurement point: In the intra-BSC handover procedure, the originating cell sends an Intercell Handover Request message to the target cell, requesting allocation of TCH. This item is measured when the target cell receives this message. It is not measured on intra-cell handover occasions. Attempted TCH seizures for interBSC incoming cell handover [2097]: Description: In the inter-BSC handover procedure, this statistic item measures the number of times the cell in Huawei BSC receives HANDOVER REQUEST messages from other BSC (transferred via MSC), requesting allocation of TCH.
