SMPP + OpenBSC

by Jesús Vega Diaz

Hi all; I have deployed one ipaccess nanoBTS 1800, with OpenBSC (osmo-nitb) and all the osmocom suite apps. I have already make succesfully GSM calls, SMS, and GPRS/EDGE packet data connections. I now want support for sending binary SMS, i have read that with SMPP i would can. I have compiled OpenBSC with SMPP but now I don´t know how to use it, i think it is in the OpenBSC vty, but i don´t know the commands or how to use the interface. If you can give me some light in this thread i will grant you. Sorry for my English Best Regards Jesús Vega Diaz

Possibility to use INET socket for external MNCC

by Luca Valtulina

Hi list, wouldn't be useful to have the possibility to choose (at least) between UNIX and INET socket to be used for connecting to an external MNCC? If this will be the case where should the choice be made? I was thinking to add an extra option to bsc_hack but the choice can also be hard-coded (prior to compilation). cheers luca

OsmoTRX on Parallella.

by Andrew Back

I wrote a blog post about running Osmocom on Parallella, with UmTRX: http://www.rs-online.com/designspark/electronics/eng/blog/building-a-gsm-ba… Just using the dual-core ARM in the Zynq, so nothing surprising/interesting to this list and it's more of just an intro. However, I'm curious as to opportunities for improving the performance by offloading parts of the transceiver to the Epiphany chip. Does anyone have any views on how practical this might be, effort involved and potential gains etc? Cheers, Andrew -- Andrew Back http://carrierdetect.com

[PATCH] oml: Pass all valid state change requests to the model

by Jacob Erlbeck

Currently ADM state change request that tries to set the administrative state to the current value are immediately ACK'ed. Beside the caching problem, this could lead the protocol inconsistencies if two such requests are sent one after the other and the second arrives before the procedure of the first has finished. This patch removes the shortcut in oml_rx_chg_adm_state() which immediately called oml_mo_statechg_ack(mo).

Fwd: OpenBSC and Roaming

by Sahil Gupta

Hi there, I'm fairly new to the mobile world and am still coming to terms with a whole new world of terminologies. The project is to test out a theory in my lab before wanting to scale this at a larger level for commercial purposes. The intent is to be able to have roaming available with a roaming aggregator in the United States with a small-scale mobile network enabled using OpenSource software. We are probably looking at implementing no more than 15 BTS's nationwide to attract roaming customers at high traffic locations. Our roaming aggregator would like us to send them MAP SS7 Messages from our MSC. My understanding of the requirements so far are: 1 x BTS (this could be a PC with some radio cards or something like a nanoBTS) 1 x MSC/BSC/VLR We won't be issuing any sim cards on our own network in the long run and hence I don't see the point in us having a unique HLR. Are there any gurus here that would be willing to share their intelligence? -- Thanks, Sahil -- Thanks, Sahil

Implement gsm340_{gen_,}scts() without using tm_gmtoff

by Daniel Willmann

Hello, this patch series depends on two patches from Alexander (once they sign handling is fixed): sms: Fix gsm340_scts() to correctly decode absolute valid times. sms: Fix support of negative timezone offsets in gsm340_gen_scts(). The first patch adds a test case to check that gsm340_scts is the inverse of gsm340_gen_scts. The next patches add a helper function to calculate the gmt offset and use those in the *_scts functions. The helper function is somewhat ugly, but it is the only portable way I could find to get the GMT offset. Ideas welcome Regards, Daniel -- - Daniel Willmann <dwillmann(a)sysmocom.de> http://www.sysmocom.de/ ======================================================================= * sysmocom - systems for mobile communications GmbH * Schivelbeiner Str. 5 * 10439 Berlin, Germany * Sitz / Registered office: Berlin, HRB 134158 B * Geschaeftsfuehrer / Managing Directors: Holger Freyther, Harald Welte

[PATCH] sms: Proper decoding and storage of SMS validity period.

by Alexander Chemeris

- Use time_t instead of abstract minutes to store validity time to make sure we support all possible values. - Return UNIX time from it to support both relative and absolute expire times. - Pass a current time to gsm340_validity_period() to compute the absolute expire time if a relative time is specified. What time is "current" is to b - We also introduce SMS_DEFAULT_VALIDITY_PERIOD macros to reduce number of magic values. PS This is a first patch of a series of patches which fix SMS validity time decoding. I'm cleaning the patch set and want to see if this patch is fine, as other patches rely on it. -- Regards, Alexander Chemeris. CEO, Fairwaves, Inc. / ООО УмРадио https://fairwaves.co

[PATCH openggsn v2] gtp: fix endianness in teid field of GTPv0 header

by pablo＠gnumonks.org

From: Pablo Neira Ayuso <pablo(a)gnumonks.org> This field needs to be in network byte order as well. This problem may manifest if you use ggsn and sgsn with different endianness. It also show up when using the gtp kernel mode since the downlink packets are using network byte order in the 64-bits teid field, which osmo-sgsn / libgtp doesn't expect. --- v2: Add function to encapsulate the code to access and to build the teid as Holger suggested.

Re: Location Area Updates missed during calls

by Luca Valtulina

Indeed the problem has been already solved in the master branch by adding the "expire_timer_stopped" attributes to a gsm_subscriber_connection and then checking it upon expiration of the expire_lu timer for an active subscriber. Sorry to have re-raised the issue. luca

Hi holger, What is a network-initiated Location Area Update? Do you talk about > the NITB/BSC advertizing periodic updating? With Location Area Update I refer to the Location Update procedure (I made confusion with the UMTS protocol where "Area" has been added in-between). I also have to apologies about that "network-initiated" which is clearly wrong since is the MS which triggers the procedure by sending a location update request signal (what I meant is that the T3212 timer is provided to the MS by the network). > > I find this behavior annoying mostly in scenarios where the T3212 (LAU > > timer) has been setup to a low value. > > About which software and which versions do you talk? mmm, I didn't quite get your question here. After performing further testing I can wrap up the issue as following: when a MS ends a call after the expire_lu time, it will be considered expired in the HLR (because two LUs were missed by the network). When the (now expired) MS initiates a call, the CM service will be rejected by the network with cause 4 (GSM48_REJECT_IMSI_UNKNOWN_IN_VLR). Needless to say that when a different MS tries to establish a call towards the (now expired) MS, this call will also be dropped because the destination MS is (seen as) detached from the BTS. Now I think that if we want to have a more precise location management, a lower expiration interval is a possibilities: this can be achieved by either lowering down the t3212 value and keeping the same expire_lu calculation (2 times t3212 + 1 minute) or by modifying the expire_lu calculation. In this scenarios the issue described above is more likely to happen (higher probability of having ~10 minutes calls than > 60 minutes). So indeed, is this behavior expected by the GSM protocol? I think that update the HLR whenever an MS exits a call will be a costless procedure which can avoid the annoyance of having the first next call dropped if this happens prior to the triggering of the LU by the interested MS. luca

[PATCH] sms_test: Use C99 initializers.

by Alexander Chemeris

Hi Holger, On Sun, Mar 16, 2014 at 1:55 PM, Holger Hans Peter Freyther <holger(a)freyther.de> wrote: > E.g. in one > of the testcases I noticed that you don't use C99 initializers but the > old/error prone way of initializing. :) Yes, I think in this particular case the old way is more compact and thus more readable. I added C99 initializers to the test (see the patch attached or achemeris/sms-fixes branch) and to me it looks less readable and thus more error prone. If you see any benefits of this patch - feel free to merge it, though. -- Regards, Alexander Chemeris. CEO, Fairwaves, Inc. / ООО УмРадио https://fairwaves.co

[PATCH 1/2 openggsn] gtp: fix wrong binary layout for struct gtp0_header in x86_64

From: Pablo Neira Ayuso <pablo(a)gnumonks.org> struct gtp0_header needs __attribute__((packed)) to make sure that gcc doesn't add a hole of 4 bytes to align the 64-bits teid, resulting in 24 bytes instead of 20 bytes.

Location Area Updates missed during calls

by Luca Valtulina

Hi list, when a MS is in a call it misses the network-initiated Location Area Update procedure(s). This inconvenience can lead (if the call ends after the expire_lu time) to having an attached (and active) subscriber marked as expired in the HLR. Furthermore if at this point the MS initiates a new call, the call will be dropped and (as expected) a new Location Area Update procedure will be initiated by the BSC. I find this behavior annoying mostly in scenarios where the T3212 (LAU timer) has been setup to a low value. To tackle this issue I thought of triggering a subscriber update when a call get released (either by the network or by the MS) for each of the MS involved in the call. The code can also be optimized by checking whether the subscriber is expired before performing the update. I can provide a patch if you also consider the above as a misbehavior of OpenBSC. cheers luca

patchwork question

by ☎

Hi. There's no patches in http://patchwork.ozlabs.org/project/osmocom-bb/list/ and http://patchwork.ozlabs.org/project/openbsc/list/ - does it mean that system went online just recently or there's something wrong with the patches hanging in ML? -- best regards, Max, http://fairwaves.ru

[PATCH 2/2] sms,db: Do not store delivered messages in the DB.

by Alexander Chemeris

In a production system we should not store messages longer than needed, as it will quickly bloat our DB. In case one wants to store messages for debug purposes, we could add one of the following capabilities later: - hexdump to a log file - send to an SMPP entry on delivery - send to Wireshark -- Regards, Alexander Chemeris.
