TCH Congestion:


TCH assign failure due to congestion (no channel available)

Formula: Failed Assignments?Channel Unavailable?/Assignment Request.

 

Huawei Formula

= 100 * Failed TCH Seizures due to Busy TCH (Traffic Channel) / (Assignment Requests

+ Outgoing External Inter-Cell Handover Requests (Directed Retry) + Outgoing Internal

Inter-Cell Handover Requests per Cell (Directed Retry)

= 100* CA312/ (CA310 + Handover Requests (Directed Retry))

 

Failed Assignments (Channel Unavailable)

CA312:CELL_ASS_FAIL_NO_CH

This counter measures the number of failed TCH (traffic channel) seizures due to no TCH available. After the BSC receives the ASS REQ message from the MSC, this measurement is triggered if the BSC cannot return the ASS CMP message or send the ASS FAIL message to the MSC.

 

Assignment Requests

CA310:CELL_ASS_REQ

This measurement provides all the assignment requests received by the BSC.

 

Handover Requests (Direct Retry)

Outgoing External Inter-Cell Handover Requests (Directed Retry) + Outgoing Internal Inter-Cell Handover Requests per Cell (Directed Retry)
