Hi Dear
Working on Nokia Systems and experiencing a strange phenomenon. First let me explain the network Heirarchy:
Nokia Ultra Site
Nokia S12 BSC
Nokia TCSM
Nokia MGW and Nokia MSS
I am facing a very high number of SDCCH A-if drops almost every 1-2 hours every day. This is not relevant to the BSC busy hour, neither the area it is serving. Now when this happens, obviously my SDCCH attempts increase and thus the SDCCH blocking.
I am not able to find any solid reason for this. But this is what I have seen only in the network where we have Nokia MGW in place. Also the MGW-MSS routing and balancing is ok, but still it happens.
kindly post your valuable experience, if you have faced the same.
Cheers
