In the measurement of Full Rate AMR Service Channel Call Drop Times, the measurement point is the same as the original service channel call drop times. The measurement is insensitive to the cause of call drops but is sensitive to full/half rate and whether the service is AMR.
Integer number or integer.
At the end of the granularity period, this counter is calculated by using the following formula.
Full Rate TCH Successful Occupancy Times (Signaling Channel) =[Channel Activation Attempts in Immediate Assignment Procedure (TCHF)] —
([CHAN ACTIV NACK Messages Sent by BTS in Immediate Assignment Procedure (TCHF)] +
[Channel Activation Timeouts in Immediate Assignment Procedure (TCHF)])
Full Rate AMR TCH Successful Call Occupancy Times (Service Channel) = [Speech Version 3 Completed Assignments (Excluding Directed Retry) (TCHF)] + [Cell Assignment Complete Times of Speech Version 3 (Directed Retry) (TCHF)]
Full Rate AMR TCH Successful Handover Occupancy Times (Service Channel) = [BSC Intra-cell Handover Detection Times (AMR) (TCHF)] + [BSC Incoming Cell Handover Detection Times (AMR) (TCHF)] + [BSC-to-BSC Incoming Cell Handover Detection Times (AMR) (TCHF)]
Half Rate TCH Successful Occupancy Times (Signaling Channel) = [Channel Activation Attempts in Immediate Assignment Procedure (TCHH)]— ([CHAN ACTIV NACK Messages Sent by BTS in Immediate Assignment Procedure (TCHH)] + [Channel Activation Timeouts in Immediate Assignment Procedure (TCHH)])
Half Rate AMR TCH Successful Call Occupancy Times (Service Channel) = [Speech Version 3 Completed Assignments (Excluding Directed Retry) (TCHH)] + [Cell Assignment Complete Times of Speech Version 3 (Directed Retry) (TCHH)]
Half Rate AMR TCH Successful Handover Occupancy Times (Service Channel) = [BSC Intra-cell Handover Detection Times (AMR) (TCHH)] + [BSC Incoming Cell Handover Detection Times (AMR) (TCHH)] + [BSC-to-BSC Incoming Cell Handover Detection Times (AMR) (TCHH)]
