Actually, the GMM attach doesn't complete, either. The messages look a bit confusing, with a bunch of Location Updating Accept followed by a final Location Updating Reject due to "Congestion". The causes may be
- two simultaneous MM attach requests from the same subscriber, - timeout after attaching, e.g. phone sends no TMSI Reallocation Complete It's hard for me to see what is going on there, take a look at the MSC's logs. As soon as the MSC attach works out, the phone will continue to try at the SGSN. ~N
