Reply To: SDCCH dimensioning for HR environment

Tam Nguyen

Hi Boboo,

I encountered this problem in many cells with little or even no SDCCH congestion while TCH drop within our target KPI. The SDCCH drop keeps too high for 2-3 days then falls down with no action, so I couldn’t find the reasons.

Where are the counters 1163/13, 1163/14, 1163/17, 1033? I couldn’t find these counters in our Ericsson BSC. If check trans problem, check TS synchronization failure?

Thank a lot
