Hi
One of our nanoBTSs startet to reboot very frequently.
The debug telnet console shows this error:

Another nanoBTS with same firmware and config works perfekt with the
same openBTS installation.
Switching to the second firmware bank and flashing a different firmware
didnt solve the problem.
Any hint where to look for more information ?

Hi, List!
I'm trying to connect OpenBSC with a real MSC.
Unfortunately I have many problems.
The first is, that every minute or so, I got these errors:
<000f> bsc_msc_ip.c:1047 The connection to the MSC was lost.
<000f> bsc_msc_ip.c:976 Lost MSC connection. Freing stuff.
<000f> bsc_msc.c:236 Attempting to reconnect to the MSC.
<000f> bsc_msc.c:230 Attempting to reconnect to the MSC.
<000f> bsc_msc.c:137 Attempting to connect MSC at 192.168.2.103:5000
<000f> bsc_msc.c:170 MSC Connection in progress
<000f> bsc_msc.c:99 (Re)Connected to the MSC.
<000f> bssap.c:92 Reset ACK from MSC
I think, it is not normal, that the communication with the MSC was lost.
Both of them (OpenBSC and MSC) are on the same Gigabit network, so
there is no connection problem...
Any idea?
Another problem: I get very oft the error:
<0000> chan_alloc.c:441 (bts=1,trx=0,ts=0,ss=0) Recycling Channel.
Any idea?
Thanks a lot!

Hi all,
i just wanted to keep you posted with the 2011 roadmap for 3G integration
into our "Free Software Mobile Network" stack. This message summarizes
the plan of what I expect to be working on. Comments welcome.
3G support directly in OpenBSC is, however, a bit more difficult than we
originally anticipated. The primary problems are:
* 3G and 2G share the same core network (CN = MSC/VLR/HLR/AuC/SGSN/GGSN)
but have different radio access netowrk (RAN = BTS+BSC vs. NodeB+RNC)
* the interface between RAN and CN is different, i.e. 'A' interface
(08.08) in GSM case, RANAP in 3G case.
* The encoding of the two protocols could not be any different. Hand-coded
vs. complex ASN.1 structures
So with OpenBSC, we face the following challenges:
1) We implement the GSM-RAN functionality and the CN in one process,
without any separation or standardized interfaces between them
2) Implementing RANAP in C can be done, but is probably quite cumbersome
given the tons of code asn1c generates and how difficult it seems to
get all the memory allocation/freeing right in all the cases
What we instead decided to do is:
a) Split the BSC part from the CN by implementing the A interface (this
is already finished, we now have osmo-bsc to do exactly that)
b) Implement a new MSC part, using the A interface towards the BSC
This is still possible using our existing code in the original
OpenBSC, though we have not completed/finished it yet.
The real goal is to have a new MSC, written in a higher-order language
that provides proper tools for working with ASN.1 - e.g. Erlang. I have
just started working on this and am more or less finished with the lower
layers like SCCP and am moving into 08.08 and the actual layer3 protocols.
There is already some initial funding secured for the first months of
this work, and funding will likely continue.
c) Once the 2G functionality of the Erlang MSC is working, add the RANAP
interface to it.
At this point we should more or less be able to directly
connect the Alcatel-Lucent femtocells, as they basically consist of
HomeNodeB plus an internal RNC handling the RRC protocol.
d) Adding support for ip.access/Cisco/AT&T will need an implementation of
their URSL protocol, which is proprietary. URSL can either be added
to the new MSC directly, or a URSL<->RANAP translater be developed.
e) Adding support for the Ubiquisys/SFR femtocell would require us to implement
the UMA protocol stack. This can once again be either done as part of
the MSC or using an external translator/gateway program.
Regards,
Harald

hello all
2day i decided to install openbsc completely neu (had some trouble with
the bs11_config), according to the website. libosmocore went thru
without problems, openbsc came to the ./configure when the problem
occured. the error was:
./configure: line 3673: syntax error near unexpected token
`LIBOSMOSCCP,'
./configure: line 3673: ` PKG_CHECK_MODULES(LIBOSMOSCCP,
libosmo-sccp >= 0.0.2)'
of course i looked at line 3673, but i'm a linux newbie, so i didnt
really understand.
in the /usr/local/lib/pkgconfig are 3 files:
libosmocodec.pc:
prefix=/usr/local
exec_prefix=${prefix}
libdir=${exec_prefix}/lib
includedir=${prefix}/include
Name: Osmocom Codec related utilities Library
Description: C Utility Library
Version: 0.1.27.16-ab12
Libs: -L${libdir} -losmocodec
Cflags: -I${includedir}/
libosmocore.pc:
prefix=/usr/local
exec_prefix=${prefix}
libdir=${exec_prefix}/lib
includedir=${prefix}/include
Name: Osmocom Core Library
Description: C Utility Library
Version: 0.1.27.16-ab12
Libs: -L${libdir} -losmocore
Cflags: -I${includedir}/
and libosmovty.pc:
prefix=/usr/local
exec_prefix=${prefix}
libdir=${exec_prefix}/lib
includedir=${prefix}/include
Name: Osmocom VTY Interface Library
Description: C Utility Library
Version: 0.1.27.16-ab12
Libs: -L${libdir} -losmovty
Cflags: -I${includedir}/
up to the configure call, everything worked fine, libosmocore was
complete installed. a makefile wasnt created -> bad!
what went wrong?

hi
to enable as many as possible of you to help me, heres what bs11_config
said (the old version):
bs11_config (C) 2009-2010 by Harald Welte and Dieter Spaar

thats the working one, the non-working says exactly the same, except
pll(1073) and work(1073)
the abis link on the 2nd is also up, but handys dont find it. the
intension ist a multi drop config, but before that, the 2 bs11 should
work on its own, right?

Hi Holger,
After trying to checkout and build the OpenBSC using command git checkout
-b on-waves/bsc-master origin/bsc-master, we got error as
fatal: git checkout: updating paths is incompatible with switching branches.
Did you intend to checkout 'origin/bsc-master' which can not be resolved as
commit?
So, may be we are not correct on the path or something else. can you please
advice, as we are not able to find bsc_msc_ip binary file.

Hello,
second try to add support to bs11_config for bport0/1 configuration. This
time with enum abis_bs11_line_cfg.
It seems sometimes creating bport1 fails, even LMT shows create obj
greyed out. Don't know why yet.
Regards,
Daniel Willmann

hello
i set one bs11 to ts 1, tei 25 and the other one to ts 6, tei 25(also
tried 26 with the 2nd), according to openbsc.cfg.2-2. the cabling is
also correct, due to a schematic from harald. but the 2nd bs11 not
recognised.
the funny thing ist, when i configure the 2nd bs11 exactly like the 1st
one(the working one, ts 1, tei 25), it don't work. the parameter from
bs11_config query are the same like the 1st, but i don't get the abis
link up

Hello Christian,
Thank you very much for the links.

Thats interesting, the ublox 5 GPS module I was playing with only
provides those data if you have the so called "raw data premium
feature" enabled (whatever this means, I have not yet looked at
the details).

Interesting device, I wasn't aware of it (I know about the book).
Is the Source Code of the book available ? So far I have only
seen some material for download at the following site, not sure
if there is the whole content of the DVD:
http://kom.aau.dk/project/softgps/
Would be interesting to use the code with a USRP.

I had a short look at some but always had the impression that
it is not exactly what I am looking for. I guess I should try
to get a GPS receiver which provides the required data, thats
probably the easiest approach.
Best regards,

I don't think that implementing is the hard part, debugging is. You
send data which might be wrong due to some bugs in your code into a
"black-box" which does something with the data. The "black-box" will
not tell you if your data are wrong, if they are, it might just take
longer till any results are returned. So you are not sure if you are
doing the things right.
I conclude the above from my experience so far: Even phones with very
extensive tracing capabilities don't tell you much about what is going
on during their GPS position calculations. And at least I am not aware
of a GPS server I have access to who will provide those data required
for an "MS-assisted" measurement so that one could compare the own
calculation against a reference.
If someone know about a server providing those data (I am not
talking of things like "almanac" or "ephemeris" here) or knows
about existing source code to do the calculation, I would like
to know.
BTW, the book "Server-Side GPS and Assisted-GPS in Java" contains
a few nice chapters, one should not care about "Java" in the title,
only the examples are written in Java.
Best regards,
Dieter
