Problem integrating OpenBSC (osmo-nitb) with LCR
by David Perez 14 Sep '12

14 Sep '12

Hi! First of all, let me thank you all the developers and contributors of both OpenBSC and LCR. Congratulations for your amazing work! I am stuck with a problem while trying to get LCR and openbsc to work together through their unix socket (/tmp/bsc_mncc), and I was wondering if anyone on this list would be kind enough to give me some pointers. I include more details below, but this is the executive summary: I have two MS that can call each other with no problem when I start openbsc (osmo-nitb) in standalone mode (i.e. without the "--mncc-sock" option). However, when I start omso-nitb with that option, and I also start LCR, a call between the two MS cannot be establised. I think the problem may be related with the fact that LCR is not being able to identify the calling number, nor the called number, nor the IMSI of the caller. This can be seen in the following trace/debug messages of LCR: --- 000000 TRACE 13.09.12 18:17:49.248 CH(1): MNCC_SETUP_IND LCR<->BSC calling imsi= dialing number= [...] 000000 DEBUG (in apppbx.cpp/ea_message_port() line 2476): EPOINT(1) incoming call from callerid=imsi-, dialing= --- AFAIK, I'm using the latest version of each tool: I am using clones of the following git repositories, made around 10:00 AM CET today (13sep12): --- git clone git://git.osmocom.org/libosmocore.git git clone git://git.osmocom.org/libosmo-abis.git git clone git://git.osmocom.org/openbsc.git git clone git://git.misdn.eu/lcr.git/ --- At the end of this message I include a list of the last commits of these repositories, for reference. --- Executive summary ends here --- The long version of the explanation of the problem follows. I hope to have included enough information, but if you need extra details, please do not hesitate to let me know. First, without LCR, I start openbsc (osmo-nitb) in standalone mode, make a call from 2203 to 2201 (extension numbers I assigned in hlr.sqlite3), and everything works fine (the call gets established and voice flows in both directions): --- root@tli-pc-2001:/usr/local/bin# cat start-bsc-standalone #!/bin/sh echo "" echo "Starting _new_ BSC (openbsc) (=osmo-nitb) standalone..." /opt/new/openbsc/bin/osmo-nitb -c /etc/opt/new/openbsc/openbsc.cfg \ -l /var/opt/new/openbsc/hlr.sqlite3 root@tli-pc-2001:/usr/local/bin# start-bsc-standalone Starting _new_ BSC (openbsc) (=osmo-nitb) standalone... <0019> input/ipaccess.c:923 enabling ipaccess BSC mode DB: Database initialized.

Introducing libosmosim
by Harald Welte 12 Sep '12

12 Sep '12

Hi! I've been hacking away a bit on a new library 'libosmosim' whihc is scheduled to become part of libosmocore. In fact, as the automake integration has been cleaned up, I'll probably merge it master any day now. The idea of this library is to * understand the EF/DF hierarchy if GSM SIM, ETSI UICC and 3GPP USIM * provide encoding and decoding routines for at least the most important EFs * decode the binary data into a generic data structure which can be used by some form of a GUI application * be able to re-encode from the generic parsed structure into the binary form, possibly after modification from the UI * be able to transact APDUs via T0 and T1 on PC/SC and other reader interfaces, e.g. the OsmocomBB SIM interface So the primary purpose of this is to be able to have a tool for meaningful (human-readable/writable) modification of all files on a programmable SIM card, such as the sysmoSIM-GR1 (and other cards where you have the ADM PIN that gives you write permission). Other useful purposes on the horizon of the library could be: * implementation of a generic SIM/UICC/USIM simulator based on user-created input, or based on 'ripped' SIM cards (well, you have to provide the key in some way). The current status is still quite experimental, but you can already see the major parts: * mapping of APDU and TPDU (only T=0 so far) on to 'struct msgb struct osim_file_ops encode and decode callbacks for a given file struct osim_file_desc node in the hierarchical description of filesystem tree struct osim_decoded_data the runtime representation of a decoded file: struct osim_decoded_element one decoded element in a decoded file struct osim_card_sw status + bitmask + human readable description struct osim_card_profile full description profile of card, including filesystem hierarchy, status words and card-specific commands struc osim_reader_hdl represents a card reader (currently a slot in a reader, not sure really how to represent multi-slot readers like sim-banks yet). primarily consist of osim_reader_ops struc osim_card_hdl representing a card inside a reader struc osim_chan_hdl currently just a dummy. intended for logical channel support most of the existing code is in src/sim/*.c, while some not-yet-cleaned-up example code is in utils/osmo-sim-test.c. There are gaps everywhere all over the place, and I think it will take quite some time to fill those gaps. Current roadmap: * properly integrate all parts, so with a single call you can read in the tree of all EFs of a card into their in-memory representation * verify that the APIs for encoding/decoding functions work the way they are before writing 'all' the EF decode/encode routines * add more decoded element types, such as location area codes and the like So if you survived this mail until this point, I think you are a prime candidate for contributing some code. Let me know if you're interested in helping out.

MultiARFCN OpeBSC and SysmoBTS
by Daud Suleiman 10 Sep '12

10 Sep '12

Hi Harald, I can't tire of congratulating and the community for the great work you are doing in creating a free world in your own capacity! I thank you. Meanwhile, I would like to know a few things: 1. Is sysmoBTS capable of operating in MultiARFCN? Is multiARFCN implemented in OpenBSC and if so how does one go about configuring it. 2. Also after the successful implementation of CSD, are there plans for PTT over Cellular (PoC)?

fix of rtp socket binding
by Andreas Eversberg 31 Aug '12

31 Aug '12

hi, after having solved an LCR issue, i patched rtp_proxy.c the same way, because it has the same issue. 1. when next_udp_port (in rtp_socket_bind) reaches 0xfffe, the bind process will fail next time. 2. if rtp_sub_socket_bind of rtp socket succeeds and rtp_sub_socket_bind of rtcp socket fails, the rtp socket must be re-created, because it cannot not be bound again to the next higher port. 3. the port range will not wrap arround and start at 0, but at RTP_PORT_BASE. (after reaching RTP_PORT_MAX) andreas
