I have some questions:
1) When I start bsc_hack bsc_init.c first establishes OML link and
initializes the bts then it establishes RSL link and bts starts
broadcasting. However, it takes so much time to start the bts. Instead of
this I want to do the following: it establishes OML link at the beginning
and only once, then when i want to start broadcasting it establishes just
the RSL link and bts will start faster since i don't have to wait for OML
link. What should be done for this?
2) If i send one or two word messages from telnet interface it is okay. But
if i send a longer message the phone could't receive the end of the message
correctly(last words may be incomplete). Did any one encounter with this
problem? What is wrong with me?
3) Could I send SMS in which extension of the sender is text not integer.
For example, i want to send an information SMS that this is a test network.
For this purpose i want to send an SMS from 'OpenBSC'. I set the extension
of the first subscriber in database as text and tried to send the SMS but
SMS wasn't delivered. What should i do?
4) Can i add SMS externally to SMS table of database?
Thanks.

Hi all,
i compiled and configured all (mISDN, lcr, asterisk, etc...), unfortunately, when i try to place a call from the softphone to the MS, i can ear only the voice originated from the laptop to the MS and not viceversa.
I'm using it on an Ubuntu 10.4, Asterisk 1.6.2.5 and the others sources from "last git".
Configurations:
- extension.conf: http://pastebin.com/mHH46HbQ
- sip.conf: http://pastebin.com/SkPN3z6q
- gsm.conf: http://pastebin.com/C1Eckdgh
- interface.conf: http://pastebin.com/ctGapa1F
- options.conf: http://pastebin.com/6xhgL0P1
- routing.conf: http://pastebin.com/TVNvwTEB
Logs:
- osmo-nitb's log: http://pastebin.com/X10B5NjE
- lcr's log: http://pastebin.com/uLY9VAiB
- Asterisk's log: http://pastebin.com/8qzw6aMn
As you can see from Asterisk, there is a mismatch:
"NOTICE[2315]: channel.c:2960 __ast_read: Dropping incompatible voice frame on lcr/1 of format alaw since our native format has changed to 0x0 (nothing) "
I tried to set alaw / ulaw on the configurations, to change efr, fr and amr, but it didn't change nothing.
Ideas or hints for further investigations are welcome.
Regards,
Luca
Hi Jolly, all,
I spent some time figuring out why LCR and OpenBSC wouldn't want to work with
each other. The reason was the addition of an element to the MNCC structure. I
propose to send a hello packet down the MNCC socket and leave it to the client
to decide if the version is acceptable.
I will need to move the mncc header to libosmocore as osmocomBB is currently
using a copy of the OpenBSC header.

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

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.
