From dbc38882d295bdd50912ba33f544a7202f5907e6 Mon Sep 17 00:00:00 2001 From: Holger Freyther <ich(a)tamarin.(none)> Date: Sun, 5 Apr 2009 14:36:33 +0200 Subject: [PATCH] [paging] Immediately fail if we don't have something like a VLR If we don't know where to search for a GSM subscriber then do not try to page it at all. Introduce an enum value for this and call the callback from within the get_channel request. --- include/openbsc/gsm_data.h | 1 + src/gsm_subscriber.c | 6 +++++- 2 files changed, 6 insertions(+), 1 deletions(-) diff --git a/include/openbsc/gsm_data.h b/include/openbsc/gsm_data.h index 6c08b03..21b05ea 100644 --- a/include/openbsc/gsm_data.h +++ b/include/openbsc/gsm_data.h @@ -24,6 +24,7 @@ enum gsm_hooks { enum gsm_paging_event { GSM_PAGING_SUCCEEDED, GSM_PAGING_EXPIRED, + GSM_PAGING_VLR_UNKNOWN, }; struct msgb; diff --git a/src/gsm_subscriber.c b/src/gsm_subscriber.c index bfb4983..3082880 100644 --- a/src/gsm_subscriber.c +++ b/src/gsm_subscriber.c @@ -129,8 +129,12 @@ void subscr_get_channel(struct gsm_subscriber *subscr, int type, gsm_cbfn *cbfn, void *data) { /* current_bts is the current VLR of the MobileStation */ - if (!subscr->current_bts) + if (!subscr->current_bts) { + if (cbfn) + cbfn(GSM_HOOK_RR_PAGING, GSM_PAGING_VLR_UNKNOWN, + NULL, NULL, data); return; + } paging_request(subscr->current_bts, subscr, type, cbfn, data); } -- 1.6.0.4
