could u hel me about what is the reason for SD congestion ,even we have enough number of SDCCH ?for example the cell carry max 3 erlang sd traffic with 2 SDCCH(16) but some times it has 4% SD congestion,(the system is Ericsson),
tanx in adance
check whether one SDCCH TS (8 sub channels) is not working. If you have configured 1 SDCCH TS on BCCH TRX, the other on second TRX, check the second TRX. Reset that TRX or corresponding TCUC. Or, remove the SDCCH from second TRX and put on another TRX.
sorry I didn’t specified, it’s Alcatel’s TRX Control Unit Card (TCUC) and manages the signalization of TRE (transceiver equipment). For Ericsson I don’t know which part is responsible for that.
