Problem by compiling the last version
by Luca Bertoncello 02 Aug '10

02 Aug '10

Hi, list! I need the last version of OpenBSC, then I got it from git and I try to compile it. Unfortunately I get this error: make[2]: Entering directory `/home/lucabert/BSC/openbsc/openbsc' make[2]: *** No rule to make target `libsccp.pc', needed by `all-am'. Stop. make[2]: Leaving directory `/home/lucabert/BSC/openbsc/openbsc' make[1]: *** [all-recursive] Error 1 make[1]: Leaving directory `/home/lucabert/BSC/openbsc/openbsc' make: *** [all] Error 2 What is this libsccp? I just have a libsccp.pc.in. Maybe is it a new file in the project and it is not in the configure?

Hi! We now have a planet (RSS feed aggregator) for the Osmcoom project, it's running at http://planet.osmocom.org/ Please let me know if you think I should add any feeds to it. There is no strict requirement for contributions to the Osmocom project, but it should be technical and related to protocols / hacking / development of mobile telephony systems.

Channel Release Changes to Master
by Holger Freyther 30 Jul '10

30 Jul '10

Hi all, I have merged the Channel Release changes that were prototyped/used in the on-waves/bsc-master branch and basic testing shows that it is working. If you see weird things happening, please tell me and I try to figure out if it is due the changes I made or not. The problem I tried to solve was this: Assume a phone sends a SMS (allocates SAPI=3) and then we do release the channel. Now this can happen with a nanoBTS (and I think it is a bug): BSC BTS/MS RF Channel Release -> <- RF Channel Release Ack <- Release Indication SAPI=0 <- Release Indication SAPI=3 The OpenBSC code used to declare the lchan as available with the RF Channel Release ACK, we also decided to release the channel with the SAPI release indication.. So we were sending a RF Channel Release twice... Now with a loaded cell we could have re-allocated this lchan and then we release someone's else lchan... I was seeing from RF Failures, to BTS crashes with two concurrent phones doing call testing.. Our release procedure now works like this: chan_alloc.c is called to release the lchan. 1.) we remember the release reason and if we should send a SACH deactivate 2.) we declare the channel to be in state release request 3.) we start to release the highest allocated SAPI != 0 (well only three) 4.) from abis_rsl.c we will call to chan_alloc.c in case a SAPI got released and repeat 3rd). 5.) If only SAPI=0 is left we either release or send a SACH deactivate.. 6.) we send a RF Channel Release...

New cellmgr-ng git repository filled with content
by Holger Hans Peter Freyther 27 Jul '10

27 Jul '10

Hi all, I have just pushed some code to a public repository. It was written to run on an embedded Linux platform and convert from E1/MTP-Level1 to TCP/IP. Besides being hacky (I had to do more than initially planned) it provides some code for MTP-Level3 and handles the link test (SLTM/SLTA). The code is using a library that has only existed for a couple of days and need to be ported to libosmocore, the new vty code and such, it will eventually happen. regards holger

Hi, again! So, as I said in my last E-Mail, I got a new BTS (DSC1800). Now I have to configure it, so I started ipaccess-find to get his IP and then ipaccess-config to configure it. I get this error: lucabert@Luca:/tmp$ ipaccess-config -u 151/0/0 -o 192.168.1.18 192.168.1.108 ipaccess-config (C) 2009-2010 by Harald Welte and others This is FREE SOFTWARE with ABSOLUTELY NO WARRANTY Trying to connect to ip.access BTS ...

Detect phone calls
by Luca Bertoncello 25 Jul '10

25 Jul '10

Hi, list! Of course OpenBSC knows which phone-calls there are right now. I'd like to get this list. How can I do this?

Re: PATCH/RFC use recvfrom with MSG_TRUNC as flag

Hello Holger, On Fri, 23 Jul 2010 21:38:36 +0800, "Holger Hans Peter Freyther" <holger(a)freyther.de> wrote: > > PS: How big is your diff to make it compile on Windows? I have not ported the TUN calls yet. My last try for OpenBSC plus GPRS was in a Linux VM, however I had problems there with the TUN interface. I could see outgoing packets with proper NAT translation (the DNS queries from the phone) and I could also see the DNS replies "outside" the VM but they never got through to the TUN interface. Maybe its a problem related to the VM, but after this experience I decided to wait playing with the TUN interface on Cygwin because it probably makes sense to have a running reference system first. BTW, anyone having OpenBSC plus GPRS running on MacOS X ? Thats the closest to Unix I have here besides a VM. Best regards, Dieter -- Dieter Spaar, Germany spaar(a)mirider.augusta.de

[PATCH] Subscriber data in measurement report
by Luca Bertoncello 23 Jul '10

23 Jul '10

I find the measurement report of OpenBSC very difficult to read, because it is not possible to distinguish the various phones. Of course, it is possible to filter the log (logging filter imsi ...), but sometimes, as in my case, it is necessary to get the measurement reports of many phones at the same time. In this case, it is not possible to know which phone generate which report. I create a patch to solve this problem. With this patch, the measurement reports contain the lchan in which the call (or SMS) runs (just as information), the IMSI and the extension of the phone. If you are interested, here is it!
