I have just added a function gsm_bts_by_lac() which should allow you to search for a BTS based on the LAC of the called subscriber. What we're still missing (but that's an optimization) is some code that removes the LAC (or sets some 'detached' flag) in the Subscriber table once we get the IMSI DETACH. Right now, when a subscriber is called after he has DETACHed, we still try to page him. Well, I can live with that for now, we're not running out of paging slots any time soon :) Regards, -- - Harald Welte <laforge at gnumonks.org> http://laforge.gnumonks.org/ ============================================================================ "Privacy in residential applications is a desirable marketing option."
