Reply To: BHCA Load in ALU BSS



Well, the BHCA capacity is just computed accordingly to the capacity in erlangs. It depends on the values used in the ALU traffic assumptions.

When you say traffic load, it is :
total of all RTCH_Erlang_total ( TCTRE ) for all cells at the same hour…
divided by Erlang Capacity of the BSC (which is depending on configuration).

The traffic load is certainly a better way to assess the actual load of the BSC.

In B10 and in the BSC evolution only, there is this counter :
MC926 : Each time the CCP reaches the limit defined by the MAX_TCH_PER_CCP parameter.

Otherwise, that’s all I can think of… Do you see high CDR or poor CSSR during the busy hour ?
