In that case we might still have some cached authentication tuples we avoid another sendAuthenticationInfo request. * After a detach the cache expiry would make sure to eventually send a purgeMS to the HLR (which might be ignored). At the same time to make the cache work we will need to make sure to start and stop timers. In case we don't start we might accumulate subscribers. I am afraid that the above two benefits do not outweight the complexity of this implementation. Modify sgsn_mm_ctx_free to remove the entry from the list as otherwise we might double free the context from within gprs_subscriber_delete. ----------------------------------------------------------------------- hooks/post-receive -- The OpenBSC GSM Base Station Controller (+MSC/HLR/SGSN)
