The problem is that the roaming MS is able to update when served by a BTS but not when its being served by another, both being in same LA.
Home subscribers have no problem updating when served by same BTS. Checked the SS7 trace, there is no request from the visting MSC to my MSC.
Is it possible to have such selective LUs.
The same question…is it possible the LU request is sent for home imsi and not for visiting imsi. I would feel something like this wouldnt happen. If request comes for a home imsi it wld come for visting imsi too.
pls check the defination with respect to other BTS and BSC as irrespective of the IMSI the Location update must reaches the switch.
is the Location update specific to on call bases(hand-over from 1 msc to another for a roamer)or generally.??
