Dear Sir or Madam,
We are students from Poznan University of Technology in Poland.We want to
develop our GUI enhancement for OpenBSC project.It's about adding and
deleting users registered in network. We have already implemented adding
logged users, but we couldn't make this part of program, which is
responsible for deleting users when they have already logged out. Could you
give some advice, where to find appropriate place in the source code in
OpenBSC.
Thanks in advance.
Best regards
Marek Świąder
Hi all,
Does anyone know a good C/C++ library for CSN.1 bitstream
reading/writing? We're working on a GPRS implementation for OpenBTS
and we don't want to code all those RLC/MAC messages by hands when we
can do this automatically. Right now we think that the easiest way is
to re-purpose csn1 "library" from Wireshark - adopt it to OpenBTS
bitstream operations and add support for writing to bitstream. Then we
can even re-use those RLC/MAC messages already converted to macros'
for Wireshark's rlcmac dissector. But we would appreciate if someone
points us to a better way of doing this.

Hi all,
I want to know how to know GPRS channel coding. GPRS using PDCH, both
MAC/RLC data block and MAC/RLC control block is
transmitted on PDCH, although there is PACCH, PTCH, PTCCH and so on it
still PDCH. then the MAC/RLC control block is coded
with cs-1 channel coding scheme and MAC/RLC data block may be coded with
other channel coding scheme. so when received a
burst how to know what kind of MAC/RLC block it belong to and which channel
coding scheme it used?
Thanks!
Hi All,
Wondering if there is a way to create pdp request for multple imsi or msisdn.
Currently there is an option to emulate more than one pdp context, can we do the same for different imsi's or msisdn via sgsnemu as an input to sgsnemu.conf file?
Thank you in advance.

Hi,
I've just pushed a couples of changes to a branch sylvain/pending that
need to be tested. They alter the startup process for the nanoBTS
(fixing the issues some people had with starting GPRS support, when
the bts was not connecting to the SGSN). And also a fix for the Nokia
InSite startup sequence where the reset command was not sent due to
missing initialization of .do_reset.
Since I know initialization sequence can be a rather fragile process,
if people could test this didn't break anything for them, it'd be
nice.

Hi,
> That’s all I get, and it never bootstraps.
In libosmo-abis, in src/input/lapd.c line 90, try replacing 0,240000,
by 0,480000,
Also, make sure you plugged the power like 10 min before trying.
Cheers,
Sylvain
