From facb5cdfc2d20de703c90e12a62b4ca69dea278b Mon Sep 17 00:00:00 2001 From: Holger Hans Peter Freyther Date: Thu, 25 Mar 2010 05:15:09 +0100 Subject: channel requests: Add configuration to handle paging any with TCH It is possible that the MSC is not sending the channel type it needs for the operations it wants to do. Add a configuration option to assign a TCH in case of paging any requests. It can be a good idea to leave SDCCHs free for location updating requests. --- openbsc/include/openbsc/gsm_data.h | 3 +++ openbsc/src/gsm_04_08_utils.c | 10 ++++++++++ openbsc/src/vty_interface.c | 14 ++++++++++++++ 3 files changed, 27 insertions(+) diff --git a/openbsc/include/openbsc/gsm_data.h b/openbsc/include/openbsc/gsm_data.h index c8fee474b..88f8ab31b 100644 --- a/openbsc/include/openbsc/gsm_data.h +++ b/openbsc/include/openbsc/gsm_data.h @@ -626,6 +626,9 @@ struct gsm_network { enum gsm_chan_t ctype_by_chreq[16]; + /* Use a TCH for handling requests of type paging any */ + int pag_any_tch; + /* a hack for On Waves.
