Please review and test zecke/channel-release
by Holger Hans Peter Freyther 17 Dec '12

17 Dec '12

Hi, I have rebased, extended and fixed the channel assignment and release. It brings us closer to the GSM 04.08 specification but there are still sime minor violations for the abnormal handling. I have tested (using the FakeBTS) a phone not acting on the SACCH deactivate/RF Channel Release and the signalling link will be released (T3109). I have a manual SMS submit test and I can make the nanoBTS crash easily. I have rebased through each individual change and couldn't reproduce the crash. I think it is either something in the RF setup (the modem bank being too close to the BTS), the older modem firmware, etc. Anyway, please review and test the branch. I plan to merge it by Wednesday. thanks holger

Anybody else getting openbsc segfaults on IMSI Detach?
by Tobias Engel 15 Dec '12

15 Dec '12

Hi, I pulled a newer openbsc version today for the first time in several months. Now, when a phone sends an IMSI Detach, osmo-nitb segfaults. The reason seems to be: osmo_msc.c:msc_compl_l3 gets called from gsm0408_rcvmsg, which in turn calls gsm0408_dispatch which at some point ends up in gsm48_rx_mm_imsi_detach_ind, which calls msc_release_connection, which calls gsm0808_clear, which sets conn->bts = NULL. Now, back in msc_compl_l3, trans_has_conn is called, which tries to dereference conn->bts->network, which causes the segfault. It might have been introduced with Holger's patch "msc: Attempt to release the lchan immediately on IMSI Detach" (153b13b0), but that was already in July... -Tobias

GANC
by Raymond Chiu 10 Dec '12

10 Dec '12

I was Googling open source GANC and came across you web page: http://openbsc.osmocom.org/trac/wiki/osmo-ganc I am interested in learning how to program handsets to work with a GANC controller. Because I am new at this, I am not sure if it is possible to add this functionality to an existing platform and would like to learn more about existing implementations. Is there a good resource (code examples) to look view? Thank you. Raymond SMS: (703)828-7168 raymond.m.chiu.(a)gmail.com

[ast] remote asterisk context from-lcr earlyb yes tones yes hi pierre, the chan_lcr to asterisk is now an interface. you can define multiple interfaces, if you like to use different contexts. (in this case it is "from-lcr".) exten => _.,1,Dial(LCR/ast/${EXTEN:0}) in order to define what interface to be used, name it in the dial app at extensions.conf. ("ast" in this case.) regards, andreas

Can someone share their configuration files used to run openbsc with new LCR? The newest LCR branch jolly/new does not seem to be understanding old configurations on openbsc wiki. Remote application=asterisk context=xyz does not work. Please help me with configuring LCR Thank you,

Several questions
by jason mercury 06 Dec '12

06 Dec '12

I have some questions: 1) When I start bsc_hack bsc_init.c first establishes OML link and initializes the bts then it establishes RSL link and bts starts broadcasting. However, it takes so much time to start the bts. Instead of this I want to do the following: it establishes OML link at the beginning and only once, then when i want to start broadcasting it establishes just the RSL link and bts will start faster since i don't have to wait for OML link. What should be done for this? 2) If i send one or two word messages from telnet interface it is okay. But if i send a longer message the phone could't receive the end of the message correctly(last words may be incomplete). Did any one encounter with this problem? What is wrong with me? 3) Could I send SMS in which extension of the sender is text not integer. For example, i want to send an information SMS that this is a test network. For this purpose i want to send an SMS from 'OpenBSC'. I set the extension of the first subscriber in database as text and tried to send the SMS but SMS wasn't delivered. What should i do? 4) Can i add SMS externally to SMS table of database? Thanks. Jason
