Hi Ellen, On Mon, Jun 04, 2012 at 09:23:21AM +0200, Ellen Apolinar wrote: adding support for a BTS model is not just a matter of writing a configuration file. The details of the used A-bis dialect have to be implemented inside of OpenBSC before it makes sense to touch a config file. To do that you should have: * One of the BTSs * A lab environment * Protocol traces of the A-bis link during startup and usage * C programming skills * Time Right now you can only use the known BTS models with OpenBSC OOTB. I hope that helps making the situation clearer. Kind regards, -Alexander Huemer

Another question which is the most important: Is it possible to use OpenBSC with UMTS instead of GSM? Regards Ellen 2012/6/4 Ellen Apolinar <ellen.apolinar.td(a)googlemail.com>

So it seems that connecting OpenBSC with an UMTS BTS is not a good idea. I have read that the developer want to try to make it possible that OpenBSC supports UMTS. But perhaps it is possible to do it by myself? The purpose of my project is to connect several BTS (GSM and UMTS) with the pc and to build an interface between both (BTS and pc) so we can test the BTS with selfprogrammed software. Our first idea is to realize this with OpenBSC. That's why I need it for GSM and also for UMTS and why I want to make OpenBSC supporting several BTS. When someone of you have ideas how to realize it with OpenBSC I would be happe of any kind of tipps. I know that this isn't done in a few weeks and that there is very much to do before it could work.

Once you have implemented support for the new BTSes in OpenBSC you will be familiar not only with the OpenBSC source code but also with other project participants. I think it's a good plan. OpenBSC can help you by being a framework in the early stages of communicating with the BTSes. You have to dive into the source code at this point. Look at how the communication with existing supported BTSes works, and start adding code for any of the BTSes you want to support. Since you have multiple to work with, start with the one that has the smallest differences to one of the already supported BTSes, which besides the BS-11, nanoBTS, and MetroSite also includes the InSite as was pointed out to me off-list. (Thanks for the correction!) Well, it depends on how different your various BTSes are from the supported ones. If you are lucky some of the code you need to write will be very easy. //Peter

Hi Ellen, I need to correct: cd openbsc src/osmo-nitb/osmo-nitb -c doc/examples/osmo-nitb/nanobts/openbsc.cfg -C Then you should see the message: <0019> ipaccess.c:841 enabling ipaccess BSC mode DB: Database initialized.
