30% for the whole network ? it is very high. I think you should focus on checking TRX unavailability. Such high congestion certainly means that many hardware resources (TRX) are down.5th December 2008 at 05:54 #51934sarvesh_nsnGuest

2. Paging proccess in B Number MSC

The paging of the called party is performed during the sDCCH phase of the calling party. So TCH is not yet allocated to the calling party.
It would be allocated as soon as the called party’s MSC is replying to the “CALL SETUP” message by a “CALL PROCEEDING” message.7th February 2009 at 18:20 #51939Azzazi_RFoptimization_engGuest
for 30% congestion on the network, 1-check the traffic per cell and the number of installed TRX’s
2-check the usage of full rate and half rate per cell.8th February 2009 at 13:16 #51940AyatGuest
