[PATCH 0/1] Add bport0/1 support for bs11_config

by Daniel Willmann

Hello, second try to add support to bs11_config for bport0/1 configuration. This time with enum abis_bs11_line_cfg. It seems sometimes creating bport1 fails, even LMT shows create obj greyed out. Don't know why yet. Regards, Daniel Willmann Daniel Willmann (1): Add {create,delete}-bport1 and bport0-{star,multidrop} to bs11-config openbsc/include/openbsc/abis_nm.h | 10 +++++++++- openbsc/src/abis_nm.c | 31 +++++++++++++++++++++++++++++-- openbsc/src/bs11_config.c | 26 ++++++++++++++++++++++++++ 3 files changed, 64 insertions(+), 3 deletions(-)

Patch: parsing of Software Activate parameters

by Mike Haben

Hi all, Patch-file is attached - addresses a FIXME in abis_nm.c, parsing the parameters passed by a Software Activate request. I've tested this on three different IpAccess BTSs (including one which didn't work with the original code), would be good if someone could check it on a BS11. Best regards, Mike H.

[RFC] Changes to the lchan and BSC/MSC split

by Holger Freyther

Hey guys, back in January I added ref-counting to the lchan and it has worked to some degree, and we have seen ref-leaks as well (fixed thanks to Andreas). Currently I'm working on integrating OpenBSC into a real MSC at on-waves.com and this has made me read the GSM08.08 specification a bit more. I would like to implement the following. - Remove the refcount from lchan - Replace it with the "transaction" concept. On certain 04.08 messgaes (e.g. paging response, various MM messages) open a transaction from BSC to MSC code. The channel is bound to the transaction. The lchan is getting released when the transaction is finished, in case of the "RSL chan" is going away too early there will be a "clear" signal/method called from the BSC and the MSC side is asked to let it go. The benefit of this: - BSC and MSC are better separated - My MSC code could wrap the transaction into a SCCP connection - Channel leak == transaction_free not getting called. regards holger

LAC 0 / paging to all BTS

by Harald Welte

Hi Zecke, I've been reviewing some of your patches: > commit 45f9b3d3fc47074652be951eb74df2b0be2a230f > Author: Holger Hans Peter Freyther <zecke(a)selfish.org> > Date: Fri Aug 21 05:30:19 2009 +0200 > > [paging] Use one of the two reserved LAC to page every BTS > > For the on-waves.com MSC case we want to page every BTS reached > of the network. Our gsm_subscriber entry does not have a LAC > entry set and defaults to zero. Use the reserved 0x0000 to > indicate that we want to use every bts in the network. > > This will influence the paging code to start and stop paging. The problem is that in the current code, we use LAC == 0 to indicate that the subscriber has sent an IMSI DETACH message, i.e. switched his phone off. You are now redefiniing the LAC 0 to something like the opposite case, which I don't particularly like. Is there some alternative solution?

OpenBSC, nanoBTS and Asterisk integration

by Sylvain Munaut

Hi, This week end I started coding a channel driver to integrate OpenBSC and Asterisk directly. You can find the code here http://github.com/smunaut/ast_chan_openbsc The current public version is what I coded this Saturday, it doesn't do much, only registers itself as a channel driver and runs the openBSC core within asterisk. It will work only for the ip.access at first (at least) because I'm directly bridging the RTP audio from the nanoBTS to the RTP subsystem of Asterisk. I spent a good part of today hacking together enough code to make a call and it worked, I got bidirectional audio. This latest code is not public yet because it's just a big mess and only take care of setup and not cleanup (so you can do 1 call and then restart :) With this hack, I just wanted to confirm that it could work without too much problem. I will try to clean it up ASAP and publish it so that there is a minimal functionality testable :) OTOH, my time is limited and I split it between OpenBSC, OpenBTS and airprobe so some weeks may be slow.

Quick & Dirty test of the ciphering functions

by Sylvain Munaut

Hi everyone, This evening I spent a few hours hacking a small test to activate ciphering and I tought people might be interested with tinkering with it. If you want to try for yourself, start off from the encryption branch of Harald, then apply the 4 patches I just posted to this list then apply the quick hack attached to this message. This patch is not for merge since it's a gross hack just 'to see if it works', and it does ! ( See the log in attachment ) What this patch does is pretty simple: - When there is a location update, it does a AUTHENTICATION REQUEST with a static RAND. - When the AUTHENTICATION RESPONSE is received, it compares the result with the 'known expected' results (see the wiki for AT commands to get SRES and Kc for a given RAND) - When sending a SMS to the MS, it activates the ciphering after receiving the paging response with the 'known precomputed' Kc. If everything goes well, the ME sends back a CIPHER MODE COMPLETE and the rest of the talk is ciphered. The included patch uses A5/2 but can be trivially modified for A5/1. I just wanted to see if the iPhone would accept A5/2 and it doesn't (works with A5/1 tough) ! My old Ericsson T610 takes A5/2 and A5/1. Of course, this is no where near a good implementation but at least it provides proof that the lower level functions works. I'm not sure what's the best solution to get SRES and Kc. Most of the time getting the Ki is not an option, so either we have a fixed RAND, or a bunch RAND and corresponding SRES and Kc ... Or a side channel to run the algo on the phone itself ... Sylvain

[patch 1/4] gsm_04_11: Free transaction on RX_RP_ACK for SMS

by Sylvain Munaut

commit 90e04861aa587d192025dd42aff5501e3742672a Author: Sylvain Munaut <tnt(a)246tNt.com> Date: Thu Sep 24 01:32:41 2009 +0200 [gsm_04_11] Free transaction on RX_RP_ACK for SMS When only one SMS is sent, the freeing of the lchan will automatically free all transactions on the lchan. However, if there are several SMS sent at once, the call to gsm411_send_sms_lchan will create a new transaction with the same caracteristics as the previous one. If the old one is not free'd, the next call to trans_find_by_id (triggered by the next incoming RP-ACK) will not return the good transaction and things go haywire.

SMS delivery (Mobile Terminated): First ok, second fails

by 246tnt＠gmail.com

Hi, I've noticed a problem when delivering several SMS to a mobile back-to-back. The first one is ok, the second one is received by the MS but OpenBSC fails with "RX RP-ACK but no sms in transaction?!?" when receiving the "RX SMS RP-ACK (MO)" (full log below) From the symptoms and looking at the code, I would say that the transaction of the first SMS delivery was not freed, therefore, when we receive the RP-ACK of the second SMS, we do a trans_find_by_id in gsm0411_rcv_sms, and we actually find the transaction of the _first_ deliver (which has its .sms field cleared since it was released already). I think you wouldn't notice if you waited between SMS because SMC Timer TC1* would expire, calling trans_free(). The problem is that I don't really know _where_ trans_free should be called. There are commented out call to it at several places ... I would think the RP-ACK(MO) reception looks like a good place. But OTOH, this whole process can queue data, giving away a reference to lchan (without get) and trans_free does a put on lchan (so I guess that could invalidate the lchan ref that was queued ? didn't check that in details) Sylvain --- SNIP --- <0100> gsm_04_11.c:920 send_sms_lchan() <0002> transaction.c:69 subscr=0x1fe52d0, subscr->net=0x1f8fc30 <0002> gsm_subscriber_base.c:131 subscr 46332 usage increases usage to: 4 <0002> gsm_04_11.c:937 lchan (bts=0,trx=0,ts=0,ch=0) increases usage to: 1 <0100> gsm_04_11.c:972 TX: SMS DELIVER <0100> gsm_04_11.c:188 TX: CP-DATA trans=4 <0100> gsm_04_11.c:149 GSM4.11 TX 49 01 1e 01 2a 07 91 44 77 58 10 06 50 00 12 00 05 b9 72 65 f7 00 00 90 80 72 12 03 41 00 02 44 3a <0001> abis_rsl.c:1215 channel=(bts=0,trx=0,ts=0) chan_nr=0x20 sapi=3 DATA INDICATION <0100> gsm_04_11.c:817 trans_id=c RX SMS CP-ACK <0001> abis_rsl.c:1215 channel=(bts=0,trx=0,ts=0) chan_nr=0x20 sapi=3 DATA INDICATION <0100> gsm_04_11.c:817 trans_id=c RX SMS CP-DATA <0100> gsm_04_11.c:191 TX: CP-ACK trans=4 <0100> gsm_04_11.c:149 GSM4.11 TX 49 04 <0100> gsm_04_11.c:750 RX SMS RP-ACK (MO) <0002> gsm_subscriber_base.c:139 subscr 27567 usage decreased usage to: 0 <0002> gsm_subscriber_base.c:139 subscr 46332 usage decreased usage to: 3 DB: Found Subscriber: ID 2, IMSI 206205003327508, NAME '', TMSI 1666608304, EXTEN '27567', LAC 1, AUTH 1 DBI: -7: The requested variable type does not match what libdbi thinks it should be <0002> gsm_subscriber_base.c:131 subscr 46332 usage increases usage to: 4 <0100> gsm_04_11.c:920 send_sms_lchan() <0002> transaction.c:69 subscr=0x1fe52d0, subscr->net=0x1f8fc30 <0002> gsm_subscriber_base.c:131 subscr 46332 usage increases usage to: 5 <0002> gsm_04_11.c:937 lchan (bts=0,trx=0,ts=0,ch=0) increases usage to: 2 <0100> gsm_04_11.c:972 TX: SMS DELIVER <0100> gsm_04_11.c:188 TX: CP-DATA trans=4 <0100> gsm_04_11.c:149 GSM4.11 TX 49 01 1f 01 2a 07 91 44 77 58 10 06 50 00 13 00 05 b9 72 65 f7 00 00 90 80 72 12 03 41 00 03 47 39 19 <0001> abis_rsl.c:1215 channel=(bts=0,trx=0,ts=0) chan_nr=0x20 sapi=3 DATA INDICATION <0100> gsm_04_11.c:817 trans_id=c RX SMS CP-ACK <0001> abis_rsl.c:1215 channel=(bts=0,trx=0,ts=0) chan_nr=0x20 sapi=3 DATA INDICATION <0100> gsm_04_11.c:817 trans_id=c RX SMS CP-DATA <0100> gsm_04_11.c:191 TX: CP-ACK trans=4 <0100> gsm_04_11.c:149 GSM4.11 TX 49 04 <0100> gsm_04_11.c:750 RX SMS RP-ACK (MO) <0100> gsm_04_11.c:640 RX RP-ACK but no sms in transaction?!? <0100> gsm_04_11.c:561 TX: SMS RP ERROR, cause 111 (Protocol Error) <0100> gsm_04_11.c:188 TX: CP-DATA trans=4 <0100> gsm_04_11.c:149 GSM4.11 TX 49 01 04 05 2a 01 6f <0001> abis_rsl.c:1215 channel=(bts=0,trx=0,ts=0) chan_nr=0x20 sapi=3 DATA INDICATION <0100> gsm_04_11.c:817 trans_id=c RX SMS CP-ACK <0100> gsm_04_11.c:159 SMC Timer TC1* is expired, calling trans_free() <0002> transaction.c:101 lchan (bts=0,trx=0,ts=0,ch=0) decreases usage to: 1 <0002> gsm_subscriber_base.c:139 subscr 46332 usage decreased usage to: 4 --- /SNIP ---

Hi all! I have recently been informed there is a job opening related to OpenBSC in Dresden / Germany. So if you're interested in working full time on issues such as * integrating OpenBSC into actual applications / products * testing OpenBSC with various handsets in various scenarios * sending bug reports and interacting with actual developers The job is not really about development of the OpenBSC stack itself, but related to system integration. So don't worry if you are neither a full-blown programmer, nor know the GSM protocol specs up to the last bit .. Please drop me a note, in case you're interested.

Ericsson RBS 2401 Status

by Caleb Pal

Hello all, Just thought I would give everyone an update on my progress with the Ericsson RBS. I got a T1 card, a Digium TE122P (http://www.digium.com/en/products/digital/te122.php). This card support E1/T1/J1. The 2401 I have only supports T1, otherwise I would have gotten a HFC based chipset that OpenBSC supports. The TE122P uses the DAHDI drivers, which used to be Zaptel. In reading through the list archives, I found a couple tidbits about Zaptel. The first was back in February from Harald: http://lists.gnumonks.org/pipermail/openbsc/2009-February/000023.html. I didn't see any updates after that. Were there updates made to make the integration with other drivers easier? The next I found was in March from Klaus-Peter Junghann: http://lists.gnumonks.org/pipermail/openbsc/2009-March/000064.html. It looks like he actually got the Zaptel driver to work. I'm not sure how much of Zaptel has changed when the driver set was renamed to DAHDI. I did not see a post from Mr. Junghann with the zaptel input module he spoke of. I'm not sure what the interest level is with getting OpenBSC to integrate with Ericsson RBS's? Like I previously mentioned, I am not much of a coder, so I can't help much in that department. That being said, I am willing to provide remote access to all the resources I have here (Debian Linux 5.0 Server, RBS 2401, Windows LMT). I can also provide access to a spec an (which would be accessed via software on the Windows LMT) if needed down the road. I am going to look into a STA to test on a couple ARFCN's in the GSM1900 band, and I am more than willing to help with handset debugging at that stage. I have quite a few different handsets lying around! Thanks much, Caleb

Motorola V3 Force ARFCN

by Caleb Pal

Hello, While experimenting with a Motorola V3 GSM branded for AT&T, I enabled the Engineering Menu with a SEEM edit. Not a terribly hard procedure once you know where to look. After performing this hack, I looked in the Engineering Menu, and there is an option to force the ARFCN the phone camps on. I think this would be a useful tool if you want to force a handset to camp on your Base Station. I'm not if it will help with the clock issues, but it might alleviate some frustration. The Original V3's (no 3G) can be found on ebay for a decent price. I'm not sure if any other phones include this functionality (I haven't come across any), so I thought I would share it with you all. If you need help performing the SEEM edit, let me know. Caleb

AW: new release of LCR (linux-call-router)

by Andreas.Eversberg

hi harald, >Of course this will mean that we need to develop the RTP-to-MNCC integration, since nanoBTS voice channels arrive on RTP. I am willing to look into this, but I presume you also have a big interest in that (and maybe more time?). i am interested having RTP audio available to MNCC interface as well. the audio stream (frames) should be equal for BS11 and nanoBTS, so both streams work for MNCC interface without different handling on the application side. for this i would like to cross-convert the frame coding of BS11 to the actual gsm format inside OpenBSC instead of just forwarding the TRAU frame format. if the TRAU frame is converted inside OpenBSC, calls from BS11 to nanoBTS would also be possible. >Since I now own more nanoBTS, I could send you one for 1-2 months of development of that code. Are you interested in this? yes, i am. this way it is easier to run some tests. regards, andreas

DTMF processing errors

by Sergey V. Efimoff

Hello All, While testing DTMF facilities of OpenBSС I've discovered a couple of bugs. The first bug is generic to GSM TS 04.08, minor and is connected with gsm0408_cc_msg_names variable (gsm_04_08_utils.c). I've found that message names order is wrong: in original source it is enumerated as ... "unknown 0x3b", "STATUS", "unknown 0x3c" "NOTIFY" ... while it should be ... "unknown 0x3b" "unknown 0x3c" "STATUS" "NOTIFY" ... thus faling to identify GSM 04.08 STATUS messages. The second problem is connected with DTMF message sequence. According to the GSM TS 04.08, DTMF message flow is the following: MS -----> START_DTMF MNCC_START_DTMF_IND ----> MNCC MNCC_START_DTMF_RSP <---- MNCC MS <---- START_DTMF_ACK MS ----> STOP_DTMF MNCC_STOP_DTMF_IND ----> MNCC MNCC_STOP_DTMF_RSP <---- MNCC MS <---- STOP_DTMF_ACK This is correct, but some mobile equipment (for example, my iPhone and Nokia 6150) do not reply with STOP_DTMF message; instead of this, they reply with STATUS message (type 0x3D). This type of messages is not processed within OpenBSC. Message is left unhandled in this state and further DTMF transactions become impossible because MNCC does not receive DTMF_STOP. GSM standard says that STATUS message reports about some errors occurred during transaction, but I did not explore the message still, though, I can do that if it is interesting for developers. I have no ideas why some of my mobile phones behave wrong, while others work correctly. I still don't know how to deal with STATUS messages properly, so I've simply added processing entry to the datastatelist[] variable in gsm_04_08.c which describes a call to gsm48_cc_rx_stop_dtmf when received a STATUS message. It is incorrect, I know, but, however, temporary helps to process DTMF messages with MS equipment which have wrong DTMF sequence flow. Now it looks like this: MS -----> START_DTMF MNCC_START_DTMF_IND ----> MNCC MNCC_START_DTMF_RSP <---- MNCC MS <---- START_DTMF_ACK MS ----> STATUS MNCC_STOP_DTMF_IND ----> MNCC MNCC_STOP_DTMF_RSP <---- MNCC MS <---- STOP_DTMF_ACK Sergey.

hi, to connect multiple BS11 to one single E1 interface via cascade, a special patch was required. now it is part of the mISDN GIT. (socket branch) use these module options: modprobe hfcmulti dmask=0x00000042 bmask=0x0000003c,0x00000780 debug=0x40000 the dmask will give a dchannel mask for the first E1 interface. multiple masks can be given for multiple E1 interfaces. the dmask will have bit set for each dchanne. in the example we have two bits set: slot 1 and slot 6. the bmask will give a bchannel mask for each given dchannel bit: for dchannel on slot 1 we use slot 2,3,4,5 for bchannel for dchannel on slot 6 we use slot 7,8,9,10 for bchannel the debug option displays initialization of E1 card on dmesg. misdn_info: Port 1 'hfc-e1.2-1': TE/NT-mode PRI E1 (for phone lines & E1 devices) 4 B-channels: 2-5 -------- Port 2 'hfc-e1.2-2': TE/NT-mode PRI E1 (for phone lines & E1 devices) 4 B-channels: 7-10 regards, andreas
