ip.access nanoBTS 140 - GSM1900
by philipp＠hug.cx 02 Oct '09

02 Oct '09

Hi everyone, I'm trying to get an ip.access nanobts 140 working with OpenBSC. Chaning oml ip worked. But when I try to start tests using "-l 64" or start bsc_hack it looks like it doesn't go online. I also applied a similar patch than the one from Mike Haben to handle the GSM1900 nanoBTS. Does anyone have an idea? Philipp Here's the output: ./ipaccess-config -l 64 172.16.19.39 ipaccess-config (C) 2009 by Harald Welte This is FREE SOFTWARE with ABSOLUTELY NO WARRANTY Trying to connect to ip.access BTS ...

That patch again...
by Mike Haben 02 Oct '09

02 Oct '09

Sorry about that Holger, another lesson learned - I'd manually edited the patch to remove an extra line. Now recreated from scratch. Very much like Harald's idea of reading the model / frequency-band from the unit - may end up with GSM_BTS_TYPE_NANOBTS_OLD and GSM_BTS_TYPE_NANOBTS_NEW or similar? Best regards, Mike H.

Patch: parsing of Software Activate parameters
by Mike Haben 01 Oct '09

01 Oct '09

Hi all, Patch-file is attached - addresses a FIXME in abis_nm.c, parsing the parameters passed by a Software Activate request. I've tested this on three different IpAccess BTSs (including one which didn't work with the original code), would be good if someone could check it on a BS11. Best regards, Mike H.

[RFC] Changes to the lchan and BSC/MSC split
by Holger Freyther 01 Oct '09

01 Oct '09

Hey guys, back in January I added ref-counting to the lchan and it has worked to some degree, and we have seen ref-leaks as well (fixed thanks to Andreas). Currently I'm working on integrating OpenBSC into a real MSC at on-waves.com and this has made me read the GSM08.08 specification a bit more. I would like to implement the following. - Remove the refcount from lchan - Replace it with the "transaction" concept. On certain 04.08 messgaes (e.g. paging response, various MM messages) open a transaction from BSC to MSC code. The channel is bound to the transaction. The lchan is getting released when the transaction is finished, in case of the "RSL chan" is going away too early there will be a "clear" signal/method called from the BSC and the MSC side is asked to let it go. The benefit of this: - BSC and MSC are better separated - My MSC code could wrap the transaction into a SCCP connection - Channel leak == transaction_free not getting called. regards holger

LAC 0 / paging to all BTS

Hi Zecke, I've been reviewing some of your patches: > commit 45f9b3d3fc47074652be951eb74df2b0be2a230f > Author: Holger Hans Peter Freyther <zecke(a)selfish.org> > Date: Fri Aug 21 05:30:19 2009 +0200 > > [paging] Use one of the two reserved LAC to page every BTS > > For the on-waves.com MSC case we want to page every BTS reached > of the network. Our gsm_subscriber entry does not have a LAC > entry set and defaults to zero. Use the reserved 0x0000 to > indicate that we want to use every bts in the network. > > This will influence the paging code to start and stop paging. The problem is that in the current code, we use LAC == 0 to indicate that the subscriber has sent an IMSI DETACH message, i.e. switched his phone off. You are now redefiniing the LAC 0 to something like the opposite case, which I don't particularly like. Is there some alternative solution?

From: Sylvain Munaut <tnt(a)246tNt.com> This is a regression coming from the recent split of the handle_ts1_read method in two.

OpenBSC, nanoBTS and Asterisk integration
by Sylvain Munaut 30 Sep '09

30 Sep '09

Hi, This week end I started coding a channel driver to integrate OpenBSC and Asterisk directly. You can find the code here http://github.com/smunaut/ast_chan_openbsc The current public version is what I coded this Saturday, it doesn't do much, only registers itself as a channel driver and runs the openBSC core within asterisk. It will work only for the ip.access at first (at least) because I'm directly bridging the RTP audio from the nanoBTS to the RTP subsystem of Asterisk. I spent a good part of today hacking together enough code to make a call and it worked, I got bidirectional audio. This latest code is not public yet because it's just a big mess and only take care of setup and not cleanup (so you can do 1 call and then restart :) With this hack, I just wanted to confirm that it could work without too much problem. I will try to clean it up ASAP and publish it so that there is a minimal functionality testable :) OTOH, my time is limited and I split it between OpenBSC, OpenBTS and airprobe so some weeks may be slow. Sylvain
