Well,
Problem was like ..
When someone try to call the MS which is not reachable(in real),MSC was playing announcement that Number does not exist..
MSC guys likely to be shout on us as Gs was enable for paging & only SGSN attach subscribers were facing d issue..!!
But It was concluded that SGSN won’t monitor this paging request as it will not repeat any PAGING-CS msg sent to bsc..
So,MSC is having timer T5,after expiry of the same,MSC should stop asking to SGSN n declare MS as unrechable..
Ultimately,Issue seems to be between timer conflict bet’n announcement & T5 expiry..
Means SGSN is not Guilty..!! LOl..
