January 2011 - OpenBSC - lists.osmocom.org

by jason mercury

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

New utility for drawing protocol ladder diagrams

by Harald Welte

Hi! With the help of graphviz, I have written a small perl-based tool that allows you to generate ladder diagrams. It can be found at git://git.osmocom.org/gen_ladder.git For your reference, I'm attaching a sample input and output file. The bent/curved arrows are a result of graphviz trying to indicate that the message is between e.g. MS and MSC and 'bypasses' BTS and BSC. I'm still waiting for somebody with more graphviz skills to make this an option. Hope this is useful for some of you... -- - Harald Welte <laforge(a)gnumonks.org> http://laforge.gnumonks.org/ ============================================================================ "Privacy in residential applications is a desirable marketing option."

Proposed OpenBSC application interface

by Harald Welte

Hi! Collin Mulliner, Tobias Engel and myself have been meeting yesterday to discuss a generic application interface for OpenBSC. They are both doing security analysis and want to achieve a clean way how an external application can get access to a more or less transparent communication channel to the phone. The purpose of this is to be able to send intentionally malformed packets to the mobile phone GSM stack at various different levels within the stack. As of now, they have both hacked some custom code into openbsc that gets them half way where they want to be - but not quite all the way. The requirements can be summarized as follows: 1) Ability to establish a SDCCH or TCH channel by paging the phone As of now, the 'silent call' feature from the VTY already does this. 2) Ability to send arbitrary layer3 protocol messages to the phone Adding this is relatively easy (use rsl_sendmsg on the lchan from the silent call) 3) Ability to receive responses from the phone, as well as error conditions such as 'readio link failure'. We don't have a solution for this yet, and we also have no clean way to identify what might be a response from the phone to the external app, and what might be a message from the phone to the normal network code in OpenBSC 4) Ability to selectively disable partial protocol handling in OpenBSC. Let's say you want to play with the mobile phone call control implementation. In this case, you want to make sure all CC related messages go from/to the external program and not from the regular OpenBSC network code. So what I've been thinking of as a solution to the problem: * store a bypass_flags bitmask related to the subscriber structure, where we indicate values such as BYPASS_RR, BYPASS_MM, BYPASS_CC, BYPASS_SAPI3. * if we process an incoming message from the MS in gsm0408_rcvmsg(), we check if a bypass flag matching the message is found. If yes, forward the message to the external program * if we want to send a message from our own protocol stack to the MS, we check if a bypass flag matching the message is found. If yes, we drop the message that we were about to send. * any messages received from the application will be forwarded to the MS The application interface protocol will likely have a close resemblance to RSL RLL. We need to exchange the following primitives with the application, like: * ESTABLISH REQUEST -- app requests a channel be established to MS (by IMSI) * ESTABLISH CONFIRM -- network confirms a channel has been established * ESTABLISH INDICATION -- network tells app connection was made by MS * [UNIT] DATA REQUEST -- app requests data to be sent to MS * [UNIT] DATA INDICATION -- network indicates data was received from MS * ERROR INDICATION -- network tells app something went wrong * RELEASE REQUEST -- app asks network to release channel * RELEASE CONFIRM -- net tells app that channel was released (as rqd) * RELEASE INDICATION -- net tells app that channel was released (by MS) The channel_number of RSL (indicating on-air timeslot) doesn't make much sense in this context, of course. The link_identifier on the other hand is great as it allows the app to indicate SDCCH/FACCH or SACCH as well as the SAPI. The actual RSL-like protocol would be encapsulated by UDP and available on a socket of the MSC. What do you think?

GPRS - local and foreign TLLIs

by Luca Melette

Hello everybody, after setting up a nanoBTS with OpenBSC/SGSN/GGSN, I had some troubles trying to connect my smartphone to the GPRS cell. Investigating the BTS-to-SGSN traffic, I saw that the frames sent by the SGSN were all marked with the same N(U) value (at LLC layer), the value was 0. With some debug, I found that the there was a mismatch in the TLLI storage, used to keep the status of attached terminals. The mentioned code is contained in gprs_llc.c, involving LL Entity functions and gprs_llc_tx_ui(). /* look-up or create the LL Entity for this (TLLI, SAPI) tuple */ lle = lle_by_tlli_sapi(msgb_tlli(msg), sapi); if (!lle) { struct gprs_llc_llme *llme; LOGP(DLLC, LOGL_ERROR, "LLC TX: unknown TLLI 0x%08x, " "creating LLME on the fly\n", msgb_tlli(msg)); llme = llme_alloc(msgb_tlli(msg)); lle = &llme->lle[sapi]; } The TX function uses the previously received TLLI to lookup for the LLE. The lle_by_tlli_sapi() performs the search, but preliminary it applies a foreign2local TLLI conversion to ensure to have a local one. Since no valid entry for the searched TLLI is found, a new one is created. And the problem is here. The new entry has the foreign TLLI. Next time the lookup fails again, and a new entry is created. This way, the counter N(U) is always reset, and the mobile do not recognize the message sequence and no attach is possible. My question is about foreign and local TLLIs. I patched the lookup, avoiding the conversion, so that the LLE is found and everything works fine... but... What is the sense of the conversion? Should the TLLI be always stored as a local one? Can this problem be solved with another foreign2local while allocating new entries? Actually, my problem has been solved with that workaround. But I'm curious to know what is the right way. Hope somebody can answer :) Thanks. Cheers, LM

How to obtain one of these HSL 2.75G Femtocells?

by ste7an

This Femtocell looks both from a pricing point of view as from a hardware point of view very interesting. Now that the integration in OpenBSC looks very promising it would become a good alternative for the more expensive ip.access picocells. It seems that these HSL femtocell can not be bought without first investing in the developers pack from HSL which cost as much as 7000$. Does anyone know how to obtain one of these cells for a reasonable price? Are they already deployed by operators? Looking at the internal hardware, it may even become a substitute for the USRP's....

Re: State of the HSL Femtocell support

by Dakota C

>You would have to talk to the manufacturer and its distributors about >this. I have no commercial or other relationship with the manufacturer. I myself tried this route as I'm a student looking for an inexpensive way to work with OpenBSC, but... 1: they require a mutual shared NDA before they'll even talk prices; 2: they claim it REQUIRES their proprietary BSC software and thus you must purchase a femtocell developer kit including their A-bis specs and a bunch of stuff you don't need, inflating the price; and 3: they only offer their NDA to companies -- individuals and students need not apply. 4: ... but they DO ship internationally -- GSM1800 only. But looking at the /only/ price they mention - $7200 US for two femtocells and all the software -- why bother? You're better off buying two, maybe three NanoBTS for that price. And I also seem to question my own point #2 -- they first tell me "If you do want to use the HSL Femtocell with an alternative to the HSL BSC..." and then in the latest mail "... our femtocell is designed to be used with our own BSC" making it seem as if you're not supposed to be taking it elsewhere. Le sigh. -DC

[ADM] openbsc mailinglist address change

by Harald Welte

Hi! The 'preferred' address for the openbsc mailinglist has changed to openbsc(a)lists.osmocom.org and http://lists.osmocom.org/ However, since the latter is just a virtual instance on the same list server, the old addresses will continue to work. Please note, though, the 'List-Id' header will change the doamin name, so you may have to update your message filter scripts. Sorry for any inconvenience, but I'm just making sure all the GSM network related projects are on osmocom.org (like the recent git repository move).

OsmoSGSN status report

by Harald Welte

Hi all! Since more people are currently looking into using OsmoSGSN, let me write down some technical notes on its current status: NS (08.16) implementation (BSS and SGSN side) * complete + stable * supports NS/UDP/IP and NS/FR/GRE/IP stacking BSSGP (08.18) implementation * no support for per-BSS/per-MS flow control yet, this is WIP * otherwise complete and stable LLC (04.64) implementation, network side * No support for Async Balanced Mode (ABM), as to the best of my knowledge, it is not used if IP is transported over GPRS * Encryption stub functionality using external plugins for actual GEA encryption. GEA3 reference code is published, but we cannot redistribute it * No full support for the XID mechanism yet SNDCP (04.65) implementation * Fragmentation/defragmentation implenented but not widely tested * No full support for the XID mechanism yet * No support for any of the header compression formats * is optional anyway, but helps performance * No support for V.42bis payload compression * is optional anyway, but helps performance GPRS Mobility Management (04.08) implementation * Supports GPRS ATTACH, RA UPDATE * Known bugs with inter-cell hand-over * No access to HLR yet, i.e. all MS are permitted to enter * No persistent storage of MM state, i.e. all state is lost if process crashes or restart * We don't yet work around a fairly common MS bug which makes them try to do GPRS RA UPD without ever sending GPRS ATTACH first GPRS Session Management (04.08) implementation * Supports only one PDP Context per MS so far * Only IPv4, no IPv6 contexts yet * No persistent storage of active PDP contexts, i.e. all state is lost if process crashes or restarts * only supports one APN, routed to one single GGSN The TODO list in order of priority is: * Implement BSSGP flow control (per BSS and per MS) * Fix MM state machine issues, make sure inter-cell hand-over of GPRS works * Add access from SGSN to HLR (possibly using libosmo-{tcap,map}, maybe again a quick sqlite database hack meanwhile * Verify encrpytion support in LLC code * Work on header/payload compression I don't have a precise schedule yet for it. Anyone who wants to work on those issues is of course much welcome. Meanwhile, if you experience problems with GPRS, please take pcap files of the A-bis, Gb and GTP links and send them to me, with a detailed description of what goes wrong when. I'm happy to look at those issues and resolve them, if I get sufficiently verbose bug reports.

State of the HSL Femtocell support

by Harald Welte

Hi! Today I've done the first push of the 'laforge/hsl' branch, an attempt to support the HSL 2.75G Femtocell from OpenBSC. It is far from being complete, but you can get the BTS to start up on the right ARFCN and process location area updates and other signalling traffic. Voice support is still being worked on. To give you a quick overview of what you are dealing with: == Hardware == * Ti DaVinci TMS320DM6443A (ARM9 CPU + DSP) * Xilinx Spartan-3A FPGA (XC3SD1800A) * 128 MByte DDR-2 RAM * 128 MByte NAND flash * Realtek RTL8201 Ethernet MAC * Dual 12-bit 65Ms/sec ADC (ADS5232) * Dual 14-bit 275Ms/sec DAC (DAC5672) As you can see, the hardware is _much_ more powerful than you would ever need for a simple single-ARFCN femtocell. Using the high-speed DAC/ADC, the combined power of the FPGA (with DSP slices) and DSP, you can probably expect that they will at least want to do multi-ARFCN (if not 3G) on the same hardware at some later point. == Protocol == They use an odd down-sized minimalistic dialect of the ip.access Abis/IP. === ACS === Prior to connecting to the BSC, the cell downloads its current configuration via https, using a HTTP POST of its serial number. === IPA layer === The IPA multiplex layer does not have PING/PONG keepalives, and it does not do the ID_GET/ID_RESP/ID_CONF identification with the Unit ID. Furthermore, both OML and RSL are encapsulated in the same TCP connection. Stream identifier 0xDD is used for passing string debug messages from the BTS to the BSC. Neither OML nor RSL are implemented fully, as per 12.21 / 08.58 === RSL === It seems to have a very 'creative' interpretation of the RSL specification. Some examples: * use of SACCH INFO MODIFY instead of SACCH FILLING for default SI5/SI6 * it forgets to send RSL CHAN REL ACK on TS1...7 * it does not implement RSL CHAN MODIFY * it seems to be unable to run without DTX * it often detects RACH requests where there are none (!) === OML === OML is almost not present at all. Only software download and setting of ARFCN + BSIC are supported. No managed objects, no state transitions, no software activation procedures/events at all. The configuration of each timeslot seems to happen 'on demand', i.e. there are no OML commands to configure the timeslots, but it depends on your RSL CHAN ACT whether a timeslot will become a TCH/H or TCH/F. I have not managed to use a SDCCH/8 anywhere, just TCH/F and TCH/H as well as SDCCH/4. The BCCH _claims_ to be a Combination 4, but in reality it is a Combination 5 (i.e. including the SDCCH/4) === GPRS === GPRS is quiite odd, too. The BSSGP is encapsulated in the RSL L3_INFO_IE, this means we will have to run a NS link from the BSC to the SGSN, combining all the BSSGP links from HSL Femtocells to the BSC. -- - Harald Welte <laforge(a)gnumonks.org> http://laforge.gnumonks.org/ ============================================================================ "Privacy in residential applications is a desirable marketing option."

hello the misdn driver runs, but it seems im doing something wrong with the parameter. i have 2 bs-11, means i need 2 d-channels, right? i took the config from the hfcmulti.c-helptext which seemed sensible: d-channels on slot 1 and 17, the rest except 16 b-channels. i tried "modprobe hfcmulti dmask=0x00020002 bmask=0x0000fffc,0xfffc0000" but that doesnt seem to work.

VTY-command "drop bts connection"

by Luca Bertoncello

Hi, list! I need to restart the communication between the BTS and OpenBSC, in order to change some parameters. I think, I have to use the command "drop bts connection BTS oml". Unfortunately, I can't find this command in the VTY... I see in the code (vty_interface.c), that it is defined for the VIEW_NODE, but I can't find it in the VTY. Need I vacancy or have I to switch to some other VTY-menu?

WG: Why TDM time slot time duration is 577us ??

by Andreas.Eversberg

in addition: Traffic Multiframe Structures - The 26 traffic multiframe structure is used to send information on the traffic channel. The 26 traffic multiframe structure is used to combine user data (traffic), slow control signaling (SACCH), and idle time period. The idle time period allows a mobile device to perform other necessary operations such as monitoring the radio signal strength level of a beacon channel from other cells. The time interval of a 26 frame traffic multiframe is 6 blocks of speech coder data (120 msec). (http://www.althos.com/tutorial/GSM-tutorial-frame-structure.html) one encoded speech block lasts 20ms. 576,92307692307692307692307692308us per slot 4615,3846153846153846153846153846 per 8 slots (1 frame) 120ms per 26 frames (6 speech blocks)

Unknown issue with GGSN/SGSN

by Chris Rankine

I am trying to implement an experimental EDGE deployment using one of the DCS1800 models. (If needed for debugging purposes, I can request access to a GSM900 for GPRS only testing). I have everything compiled and running with the newest builds as of a few or two ago. EDGE works most of the time, however randomly it stops working. I have the SGSN and GGSN running, and typically during these down periods I will see messages appearing on the SGSN, but none of the typical traffic flowing messages on the GGSN (typical messages being "Received packet from tun!" and "encaps_tun. Packet received: forwarding to tun"). Typically if I wait a period of time, sometimes about 2 minutes, other times for a long time, then the connection returns. During this entire time the phone still displays the "E" meaning it believes it has an EDGE connection. If I reboot the phone I will get the PDP entry deleted and requested messages. As for the SGSN, I am new to GPRS and EDGE and I am not familiar with a lot of the terms that are appearing, so I can not comment on what is good or bad. I get the same results if I put three IPs on one VM and have it running OpenBSC, OpenGGSN, and the OpenBSC based SGSN, as compared to when I give one VM to OpenBSC and another dual homed VM hosts OpenGGSN and SGSN. I guess what I am asking is what do you suggest I should be looking into to try to figure out what is causing this problem? I have two old Android phones to play with.. So, at least for the Android phones I have better access at debugging issues on the phone. Attached below are the relevant parts of the GGSN conf, SGSN conf, and openBSC conf.

Dears, Sorry for hijacking the thread , next time I will create new thread ... I will try to bind using IP to avoid using SO_BINDTODEVICE ,and I will google IP_BOUND_IF as well. Another issue is the linux command for vty which is the c function under linux called cfmakeraw which I removed from vty.c cause there is no library under SUN for that command or function to link with. Can you please ensure that this commented line will not affect vty functionality ?

For ipaccess-find is sending a broadcast packet, so it is important to select the physical interface it should be send on. For the user it is more convenient to write the interface name then to remember the ip address of this interface. Does Solaris provide another way to bind to a specific interface? What about IP_BOUND_IF? If that is not the case we could consider doing a normal bind and bind to the interface via an ip... z. Sent via BlackBerry® from mtc touch

AW: applying multibts-patch

by Andreas.Eversberg

you don't need that patch. you can configure the hfcmulti.ko using dmask and bmask: * dmask and bmask: * NOTE: One dmask value must be given for every HFC-E1 card. * If omitted, the E1 card has D-channel on time slot 16, which is default. * dmask is a 32 bit mask. The bit must be set for an alternate time slot. * If multiple bits are set, multiple virtual card fragments are created. * For each bit set, a bmask value must be given. Each bit on the bmask * value stands for a B-channel. The bmask may not overlap with dmask or * with other bmask values for that card. * Example: dmask=0x00020002 bmask=0x0000fffc,0xfffc0000 * This will create one fragment with D-channel on slot 1 with * B-channels on slots 2..15, and a second fragment with D-channel * on slot 17 with B-channels on slot 18..31. Slot 16 is unused. * If bit 0 is set (dmask=0x00000001) the D-channel is on slot 0 and will * not function. * Example: dmask=0x00000001 bmask=0xfffffffe * This will create a port with all 31 usable timeslots as * B-channels. * If no bits are set on bmask, no B-channel is created for that fragment. * Example: dmask=0xfffffffe bmask=0,0,0,0.... (31 0-values for bmask) * This will create 31 ports with one D-channel only. * If you don't know how to use it, you don't need it! hope this helps -----Ursprüngliche Nachricht----- Von: openbsc-bounces(a)lists.gnumonks.org [mailto:openbsc-bounces@lists.gnumonks.org] Im Auftrag von Thomas Ansorg Gesendet: Freitag, 7.

[ADM] OpenBSC git repository address change

by Harald Welte

Hi all! Today, I have moved the remaining projects on git://openbsc.osmocom.org/ (aka git://bs11-abis.gnumonks.org/) to the central git://git.osmocom.org/ location. This helps us to consolidate all our git repositories on one server. The git URL of the main OpenBSC repository has changed from git://bs11-abis.gnumonks.org/openbsc.git (read-only) gitosis@bs11-abis.gnumonks.org:openbsc.git (write) to git://git.osmocom.org/openbsc.git (read-only) gitosis@git.osmocom.org:openbsc.git (write) In order to update your local repository with the new URL, simply use the "git remote set-url" command, like in the following examples. for those of you with read-only access: git remote set-url origin git://git.osmocom.org/openbsc.git for people with write/commit access: git remote set-url origin gitosis@git.osmocom.org:openbsc.git The other two repositories that have changed in similar way are openggsn.git and chan_openbsc.git.

IPA Stream IDs

by Holger Hans Peter Freyther

Hi all, I was very liberal in just using numbers from the 'open' number range. We should move to a different scheme and just take the liberty to take one ID and then have our own header inside there. I would propose to do something like this struct ipa_proto_hdr { uint16_t len; uint8_t proto; data[0]; } packed; struct osmo_ipa_proto_hdr { uint8_t osmo_proto; data[0]; } packed;. Any comments?

RFC: Relicensing OpenBSC under AGPLv3

by Harald Welte

Hi all! This subject came to my attention again recently: Why not relicense OpenBSC under AGPLv3? Right now we are licensing under GPLv2+ (v2 or any later version). However, if an operator was to make lots of private modifications and then operate it on his own network, there would be no distribution and thus no need for him to release his modified versions of the source code. This may sound a bit strange to those who have been with the project since its early days. But we are reaching production quality now, and we already have the first number of production deployments of the software. Companies like Netzing and On-waves have been FOSS-friendly and funding parts of our development effort. They have no issues with the result being Free Software again. However, there are definitely other companies out there who are less fond of sharing... So thus my idea is to put OpenBSC under AGPLv3. This way whoever uses OpenBSC _in modified form_ to operate a communications network will have to provide the source code to that modified form on a network server at no charge. The only controversial question to me is "your modified version must prominently offer all users interacting with it remotely through a computer network (if your version supports such interaction) an opportunity to receive the Corresponding Source". 1) does a gsm network count as computer network? i'd say yes. 2) is using a gsm network 'interacting with it remotely'? I'd also say yes 3) what does 'prominently offer' mean in the context of GSM? We don't want the operator to spam their users with advertisement SMS just to know that they can get the soruce code, after all. Notwithstanding those open questions, such a network operator would always have the option of simply sending back his changes for integration in the official project - and thus he would no longer use a modified version which then means there is no need for the prominent notice / download at all. We can make this very clear in the project documentation, putting further encouragement The actual relicensing should be less problematic than I thought, since AGPLv3 is compatible with GPLv3. So I could re-license all parts that I own copyright on (which should be the majority of the code base anyway) under AGPLv3, while the former GPLv2+ components (like VTY code from zebra, or contributions by other people) then become GPLv3-or-later. Of course I would want to encourage all developers/contributors to also follow the re-licensing. Particularly Holger Freyther, Dieter Spaar, Andreas Eversberg, Jan Luebbe, Sylvain Munaut, Daniel Willmann, Stefan Schmidt. So let's start with a poll: a) Do you think re-licensing to AGPLv3 is a good idea? b) If you have contributed, would you re-license your code under AGPLv3? If we have some kind of concesus in the community, I would approach On-waves whether they would want to do the same for their share of the copyright. As their "modifications" are all part of OpenBSC git repository, they would not be subject to any different conditions than before. Thanks in advance for your feedback, Harald -- - Harald Welte <laforge(a)gnumonks.org> http://laforge.gnumonks.org/ ============================================================================ "Privacy in residential applications is a desirable marketing option."
