I want to try to alter the mobile app (in gsm48_rr.c) to listen to all tmsi's.
i changed the code and altered all if statements where in the else part was the log
'Not for us'
i'm hoping the phone will start following the conversation with the immediate
assignment packages...
this way i can start logging the beginning of the encryption....
am i doing stupid things? or is there already an app that does this?
thanks

Hi,
ccch_log already does show the paging requests and immediate assignments.
have a look at the layer23 apps that are already existing.
as for logging a call, neither you modification nor this application can do it.
this is because calls are on TCH logical channels (+channel hopping in real networks), but
you only listen to the CCCH logical channel.

Heya
ccch_log already does show the paging requests and
immediate assignments.
have a look at the layer23 apps that are already existing.
Actually it is ccch_scan
:).
Also take into consideration Sylvain's explanations[1] as pointed out in the
documentation[2].
Kind regards
