Hello guys,

As I am not an experienced GSM engineer I can't fully understand the GSM 
specs.
But I found this in paragraph 4.1.1.2.1 of GSM 04.08:
"NOTE:
Whenever GMM performs a combined GMM procedure, a GPRS MS enters the MM 
state
MM LOCATION UPDATING PENDING in order to prevent the MM to perform a 
location update procedure."

Since we haven't done anything for GPRS support, this might be the 
reason why a location update is not performed with bsc_hack.

Once again, I'm a beginner on this field and still need some more 
readings and learning of GSM and OpenBSC sources.
But I hope I found the part that might lead you to solve the GPRS 
supported mobiles registering issue.

P.S.: Is everybody on holiday...:)
