Nokia Insite OpenBSC Segfault
by Caleb Pal 29 Oct '13

29 Oct '13

Hello, I decided to connect my Nokia inSite 1900MHz E1 BTS that has been sitting for a while. Shortly after I start OpenBSC, it crashes. I have attached my configuration files as well as the result from gdb. I am using a Dahdi with a TE122P set to E1 mode. openbsc.cfg ! !

Re: OpenBSC + LCR + Asterisk = half sided calls in one
by Sipos Csaba 28 Oct '13

28 Oct '13

Hey Peter, > I'd suggest to make LCR use SIP for communcation with Asterisk. See > http://stuge.se/lcr.txt for a minimal example of LCR configuration. Do you have some more example configuration files for the Asterisk end of the SIP trunk? > Since you're using bridging you might also want to try rtp-bridge > between GSM and SIP, which could allow GSM phones and SIP phones to > negotiate codec directly, avoiding any transcoding. (But maybe it > only works with Abis over IP and not over ISDN? I'm not sure.) I am almost sure that RTP bridge can only be used with IP based BTSes which I don't have. My units are connecting via E1 dahdi. > You can of course continue to debug the LCR-Asterisk module but I > would suggest moving to SIP since I think working with SIP on both > legs makes debugging a bit easier. My problem is that I made test calls an analyzed the logs at both LCR and Asterisk end, and there is no difference between a good and a half sided call. First, I forced the GSM phones to use TCH/F FR only, then I forced LCR and Asterisk SIP clients to use Alaw only (SIP clients are not supporting any GSM codec). Transcoding obviously happens between TCH/F FR and Alaw, but how on earth is possible that the direction of the call can affect that this transcoding is going to be a success or not? If its a transcoding failure it shouldn't work in any direction. If its a call routing problem, then the call shouldn't make its way to the called party. But none of this is what happens. So I really don't know where to look, or how to debug this problem. BR, Csaba

osmo-nitb openbsc sms via commandline problem.
by hulds＠gmx.net 25 Oct '13

25 Oct '13

Hi, When sending sms via openbsc commandline the sms gets extra data added to its tail. The coversion from text to PDU results in the converted data + garbage, this data is posted to the 'sms' database 'user-data' field, and then sent. in the 'sms' database you can verify that a short sms text results in long user-data phone to phone sms works without problems.

OsmocomBB without hardware phone
by clovnrian＠gmail.com 24 Oct '13

24 Oct '13

Hi, I am trying to modify osmocomBB to work without the phone as layer 1. My goal is that application will using socket to communicate with BTS (modified BTS which can send and receive message throught sockets). I analyzed the osmocomBB code and I found that I'll have to modify osmocon.c (host/osmocon/osmocon.c) file. This file is interface between serial communication and layer2. If I am right, I have to do this changes: 1. Delete functions handle the serial interface 2. Add new tool server to dnload structure 3. Creating new tool server for L1 interface (UNIX socket or IP socket with GSMTAP) 4. Add callback function for reading from layer2 socket and forward this messages to L1 socket interface. Simplified I have to listen and forward packets from BTS to layer2 socket and from L2 to L1. Do I think in right direction or I am wrong and it will need more modifications? Best regards, Miroslav Babjak

[PATCH 1/2] gbproxy: Add test for NSEI and NSVCI changes

This checks the behavior of the gbproxy when the BSS peer changes the NSEI and the NSVCI.

[PATCH 1/2] Added new auth policy blacklist.

[PATCH 1/3] gb/vty: Perform NS-VC operations based on NS-VCI
by Jacob Erlbeck 24 Oct '13

24 Oct '13

This adds a 'nsvc nsvci <0-65535> (block|unblock|reset)' vty command. It selects the NS-VC based on the nsvci instead of using the first with a matching NSEI, like it is done when the 'nsei' keyword is used instead.

Re: Hard reset NanoBTS after forgetting static IP
by Daniel Fligg 23 Oct '13

23 Oct '13

I have come across a nanoBTS 165AU but since is used and not tested from the previous owner, I guess it has set a static IP. After turned on is booting (RED light) and then remains (ORANGE not flashing) even if the eth is connected to the router. Based on observation, constant blinking orange seems to indicate the layer 2 link isn't up (eg it's powered but Ethernet isn't connected). Solid orange is good. Once it's fully booted it seems to be solid orange with a very quick flash off once a second seems to indicate it's trying to find the BSC > At the moment I am trying with ipaccess-find and BtsInstaller to find in on my LAN . > Unfortunately it is not answering and is not even getting an IP from the router by the DHCP daemon. > > ipaccess-find / btsinstaller only ever seem to find my BSCs when the machine they're running on is on the same subnet. The easiest way to track down a rogue bts is to connect it directly to a spare network port in the pc and then run wireshark on it. On boot my BTS sends a number of dhcp inform requests broadcasting it's IP and then starts blasting packets at the BSC address. Hope this helps,
