Thank you Holger and Neels. The problem is solved now. We re-checked out the latest version and right branch of OpenBSC. The previous branch may be wrong. Now the cellphone was successfully attached.

Thanks for the quick reply.
I wondered if I need to clarify but then assumed it would be obvious enough. With trace I meant packet trace to capture what is being sent between the different components.
Is a TMSI assigned? What is the TMSI?
just fond TMSI at osmo-hnbw's terminal:(0x0 not looks good )
<0001> hnbgw.c:176 created UE context: id 0x17, imsi 901700000014922,
tmsi 0x0
the phone ME might not have a TMSI initially. Not bad.
