Amber and Sarosh amber_sarosh at hotmail.comThank you for your reply.Yes, we have tested and found that change in LAC is truly effective when BTS is restarted. But we cannot understand the behavior of user (user1) which is attached to say LAC=1 and when LAC is changed to say LAC=2 , without restarting the whole system(osmo-nitb, osmo-bts and osmo-trx), only silent call stops working for user1 and rest of the functions keep working. We have found that in this case, The user1 already attached to the Old LAC will now be considered unattached for calls onlyThis user1 is however seen to be semi attached with the network as the network still logs its channel requests if a call i made by this userThis user1 can still receive SMS from the system only when it requests any channel from the systemThis user1 does not go to its real network for a long period of time Can someone explain this behavior, that a user attached to an old LAC cannot be sent a silent call but can be sent an sms and its logs and call requests are being processed too under new lac by same network when its LAC is changed without restarting the BTS? P.S. Sorry for the long email. It's done for proper understanding of the scenario.
