IIRC, Holger > later introduced the subscriber_connection when he created OsmoBSC. ok, nice, I understand. That comment in gsm48_handle_paging_resp() (libbsc) sounds a bit like more than one BTS could be involved: /* Stop paging on the bts we received the paging response */ and it uses lchan->...bts first, but conn->bts at the bottom. (But nm, this function is not relevant for the MSC-split anyway.) ~Neels -- - Neels Hofmeyr <nhofmeyr at sysmocom.de> http://www.sysmocom.de/ ======================================================================= * sysmocom - systems for mobile communications GmbH * Alt-Moabit 93 * 10559 Berlin, Germany * Sitz / Registered office: Berlin, HRB 134158 B * Geschäftsführer / Managing Directors: Holger Freyther, Harald Welte -------------- next part -------------- A non-text attachment was scrubbed...
