Hi, I am trying to punch a nanoBTS through a firewall to an instance of openBSC over layer3. I have opended TCP port 3002 (OML) and TCP port 3003 (RSL) but no green light or any traffic captured with tcpdump. Any ideas? I havent changed the default port on the bts.

socket problem again
by jason mercury 01 Dec '10

Hi , Here i want to restate my problem. I want to run two different bts with different network parameters on the same PC, at the same time. I can not achieve this with one bsc_hack because bsc has a unique mnc. I can not run two bsc_hack at the same time because they try to use the same port. I think that there might be two approaches to solve this: 1) Modifying the code such that i can specify different mnc for each bts with one executable program. Maybe, two different gsm network can be defined as network1 and network2 (similar to bts0,bts1,...). So i can give different network parameters for different networks and run them with one program. 2) Changing the communication port of nanoBTS and OpenBSC such that i can run two bsc_hack at the same. I think that it should be changed on both nanoBTS and source code. Could any one help me (at least give some hints) about how i can implement one of these approaches. Or, You could propose some other approaches. Thank you. Jason

Hello. Is anybody interested in trading nanobts for openbts testing kit? I want to do some experiments with openbsc, but I have openbts testing kit. I will be interested in trading for bs-11 as well. Please send an email to manatails007 at gmail dot com for further details Sincerely, Sent from my iPhone

Hi again, Is it possible to define a different port for second bts and bsc. Or, can i modify the source code such that i can run two different network with one program? Jason

Hi, I want to run two different nanoBTS s with different network parameters(MCC, MNC), at the same time. I think it is not possible in one configuration file. Instead, I tried to run two bsc_hack with different configuration files at the same time on the same PC. However, I got a socket problem for second bsc_hack (Could not bind socket. Already in use.) . What should i do to solve this. Should i modify the code or do something else. Thanks. Jason Mercury

DIY BTS
by Barnaby Astles 30 Nov '10

30 Nov '10

Has any one here taken a look at building a BTS? There some interesting Baseband chips available: http://www.octasic.com/en/applications/wireless/gsm_edge.php It would avoid NDAs and maybe we could just get the transmitter. Since we are not looking at building high availability stuff it could cut costs to get more interest in developing the software. P.S. There are transmitters that are being scraped by the telcos due to upgrades.

hello, built 2 bs11 interconnect cables + termination today. but the second bs11's not recongnised. i tried the 2-2 cfg-file, and mine. i want to use only one trx per bts. my cfg-file look like this: ! !

AW: Optional cell reselection parameters setting

did you push it? my head of sylvain/testing is: commit cbf5ba125a70bd18c5919d51203d836fd26fa98a [WIP] Voice IND -----Ursprüngliche Nachricht----- Von: openbsc-bounces(a)lists.gnumonks.org [mailto:openbsc-bounces@lists.gnumonks.org] Im Auftrag von Sylvain Munaut Gesendet: Sonntag, 28. November 2010 20:58 An: OpenBSC list Betreff: Optional cell reselection parameters setting Hi, I've just pushed a patch in sylvain/testing with vty commands (and support code) to support settings things such as the Cell Reselection Offset (which is in the re tst octet). If someone could just have a quick look before I put it in master. The main thing is the vty setting to support things like: penalty time <20-620> penalty time infinite I had to create two commands it seems (can specify that an arg is either a range or a keyword if I'm not mistaken). Cheers, Sylvain

Hello, About introducing myself: I am a network engineer working in the fields of VoIP and Radio Communications services at NEWITEC CONSULTING Tunisia ( www.newtechtn.com) Some of my projects done are: 1- Integration of custom SCTP and M3UA layers into the Dialogic SS7 stack for a french client. 2- Integration of a solution for SIP traversal over firewalls and nats. 3- Collaboration in the development of a GSM IP client (does authentification to a GSM network with the classic method but over IP). This work is a part of a roaming hub solution. 4- VoIP switching, billing and security. If you find my work interesting, please involve me in the development of the project. Thank you.
