ZTR106A:BSCRPT_RATE_TCH_CONG
This measurement provides the congestion ratio on the TCHs per BSC, that is, the proportion of failed TCH seizures due to busy TCH to TCH seizure requests in the case of call, handover, and early assignment.
%.
This counter is measured according to the following formula below when the measurement period ends. For details on the measurement point, see "Measurement Point" of each counter in the formula.
Congestion Ratio on TCH per BSC =
(([Failed TCH Seizures due to Busy TCH per BSC (Signaling Channel)] +
[Failed TCH Seizures due to Busy TCH per BSC (Traffic Channel)] +
[Failed TCH Seizures in TCH Handovers due to Busy TCH per BSC (Traffic Channel)])
/
([TCH Seizure Requests per BSC (Signaling Channel)] +
[TCH Seizure Requests per BSC (Traffic Channel)] +
[TCH Seizure Requests in TCH Handovers per BSC (Traffic Channel)])) x {100}
