Hi Harald Thanks for the options. I will need to look into it in a bit more detail. Which part of the code base do I need to concentrate on to get the Fr over E1 functionality? Naveen

merge of 'daniel/controlif' branch

by Harald Welte

Hi! After many delays on my side (it kept falling off my TODO list), I have finally merged the daniel/controlif branch earlier today. For those who haven't heard about it so far: It is code that allows us to remotely get and/or set attributes of the BSC. Furthermore, it supports traps (similar to SNMP traps). The idea of it is to allow us to have centralized management of networks with many OpenBSC installations, offering SNMP-like feel but without adding the complexity of SNMP (asn.1, etc.) to OpenBSC itself. We might at some point have an independent gateway process that exports the attributes through real SNMP, but that mostly depensd on whether any production networks have such a requirement or not. The control interface is implemented either stand-alone (for osmo-nitb) or via the regular A and A-bis/IP as an additional ip.access stream identifier. Thanks to Daniel for writing the code, to On-Waves for funding the development and once again my apologies for the delays. btw: I have done a couple of cosmetic clean up commits in addition to Daniels branch, hopefully I didn't break anything while doign that...

Licensing of the wiki

by Harald Welte

Hi all, so far we do not have any statement about the licensing of the content on our wiki. This means the default copyright rules apply: All the content is copyrighted, and nobody has any rgiht to reproduce it at all. I would like to propose an official license for the content in the wiki: Create Commons CC-BY-SA. The alternative would be to go for CC-BY-NC-SA, disallowing commercial use of the content. I'm not certain if NC is really what we want. After all, even somebody using OpenBSC in a commercial environment should be able to make copies of the reference documentation we have available - as long as he will releas the result again (which the SA part already covers). If the major contributors to the wiki would agree to a license, I would update the wiki accordingly.

NanoBTS reset

by Seungju Kim

Is there any other way to reset a NanoBTS without building a reset dongle? My NanoBTS is acting strangely after a segfault of OpenBSC. I can connect and beacon my network with the BTS but it won't enable data for some reason. It was working fine before. Now it says something like this <000d> input/ipaccess.c:696 accept()ed new OML link from 192.168.1.139 SET ATTR NACK CAUSE=Message cannot be performed <000d> input/ipaccess.c:758 accept()ed new RSL link from 192.168.1.139 The NanoBTS doesn't even make a connection to the SGSN when this happens. Thank you I want to kno if there is a way to reset the nanobts without making the reset dongle? ./ipaccess-config works at the moment.

Hardware required to setup an SGSN

by Naveen Kumar

I am trying to validate some functionality of a BSC that we have. The BSC will be connected via Gb interface(over E1) to an SGSN. What kind of hardware(processor/E1 card) would I need to support the SGSN ? I am mainly interested in testing ns/bssgp functionality. Thanks in advance. Naveen

[PATCH 0/4] use standalone libtalloc instead of own copy

by pablo＠gnumonks.org

From: Pablo Neira Ayuso <pablo(a)gnumonks.org> Hi! With these patches, libosmocore, libosmo-sccp, openbsc and osmo-tetra does not use anymore our own copy of talloc and they rely on the standalone library that is provided by major distributors. The osmocom-bb part is still missing, my idea is to include a copy of libtalloc in the tree in the shared/ directory via rsync. This patch will follow later since we can still rely on the outdated copy of libosmocore. Please, apply.

[PATCH 0/2] libosmocore: logging and signal support for libraries

by pablo＠gnumonks.org

From: Pablo Neira Ayuso <pablo(a)gnumonks.org> Hi Harald! These are the two patches that I'm using to support signalling and logging in the libraries. The patch that adds the logging support reworks your previous contribution so we only keep the logging subsystem in libosmocore, instead of the full definition of the logging subsystem. See patches descriptions for further details. Let me know if you're OK with these changes. Pablo Neira Ayuso (2): signal: reserve signal subsystems >= 64 for libraries logging: rework definition of logging subsystems for libraries include/osmocom/core/logging.h | 22 ++++++-- include/osmocom/core/signal.h | 23 +++++++++ include/osmocom/gsm/gsm.h | 6 ++ src/gsm/Makefile.am | 2 +- src/gsm/init.c | 22 ++++++++ src/logging.c | 107 ++++++++++++++++++++++----------------- 6 files changed, 129 insertions(+), 53 deletions(-) create mode 100644 include/osmocom/gsm/gsm.h create mode 100644 src/gsm/init.c -- 1.7.2.5

Question about how to read / send SMS from an external program

by Kang-min Liu

Hi all, I have been working on a project involved using osmo-nitb and trying to read / send SMS by doing SQL queries directly hlr.sqlite3 in a perl program, but I cannot figure out the encode/decode process on the "user_data" field. From "sms_from_text" function in libmsc/gsm_04_11.c, it appears to me that the content of user_data is a gsm_7bit_encode-ed of text if the SMS is sent with VTY interface. I then tried to port gsm_7bit_decode to perl and the implementation successfully decoded two test strings in libosmocore/tests/sms/sms_test.c. However it does not successfully decode any SMS user_data record in hlr.sqlite3 to the original text. The result looks like just a piece of garbled text, not even close to any human-readable text at all. I also tried briefly to include gsm0338 decoding process, or some other perl-based implementation from CPAN, no success at all. I am currently out of ideas to try. It will be really appreciated if anyone with similar experience can offer insight to my issue here.
