Let me know if this helps with the discription of what is going on. This is not my cup of tea so I might not be using the correct terminology. When someone calls one of our subs, the VLR is checked to see what sector the sub was last on. Then a page is sent out to that sector. If the mobile does not respond then the mobile is paged at the LAC level and if the mobile does not respond then the page is sent out to the complete network. I was told this happens becuse the mobile loses registration and does not do a MZ detach. Is this a normal situation? Thanks.
