1-we have a Huawei BSC with 2 LAC and 5800 Erlang and 6 Siemens BSCs with 1500 erlang traffic per BSC.they worked nice.
we swapped our MSC from ERICSSON to Huawei MX3000 MSC.
but unfortunately we face to TCH_Assignment_failure = 2% in whole of Huawei sites in all of Huawei bsc.
what is your advice?
2-is it wise we divide huwaei bsc to 2 new bsc?!
