Hi to all. I have a very challenging EVDO connection problem on a phone that I'm troubleshooting. The phone works properly on 1x voice/data and is able to acquire an EVDO channel. From a layer 2/3 trace (see below) it can be seen that the phone sends a route update/connection request message to BTS-BSC (AN) and then recieves a L2 acknowledgement from the AN but the AN never assigns a traffic assignment.
Can someone with message analysis experience give some tips, ideas, opinions on why this may be happening. One thing, the phone is an MEID type. The MEIDSUP switch in the BSC is set to OFF (can only be switched ON with license [BSC6600]).
I would appreciate some insite into this from other experts here.
