Final review of L1SAP ported to current maste
by Harald Welte 25 Mar '15

25 Mar '15

Dear all, the valuable L1SAP abstraction has been sitting out of master for too long time. It is a pity that this has taken so long. I've finally been able to put some time into osmo-bts again and reviewed the following patch series. It consists of mostly Andreas' work, interspersed with smaller patches/fixups that I introduced after the respective original patch from Andreas. I have started a sysmobts between all of the major steps in this patch series and did a short manual tests involving registration (LU) of two MS, mobile-to-mobile call and vty-to-mobile SMS. So far I couldn't see any problems. What has not been tested yet is the PCU interface as well as encryption support. I plan to do this later this week. I intend to merge the code after this current review cycle. Please take your time to have a look and provide feedback (if any), so we can get this over and work on new features again, rather than infrastrutural changes. I didn't yet rebase the osmo-bts-trx interface on top of the L1SAP, as I don't have a hardware setup for it, and I will leave it to the owners of such hardware to publish/push the respective code after L1SAP is merged.

Error - Installating libosmo-abis
by Amber and Sarosh 22 Mar '15

22 Mar '15

Hi, I am trying to configure and run OsmoTRX,OsmoBTS, OsmoNITB and LCR as per instructions at ; http://openbsc.osmocom.org/trac/wiki/network_from_scratch After installation of libosmocore when i run ./configure in libosmo-abis-master , I get the error below every time. Please note that I have installed libosmocore-0.6.0 but some how even while running pkg-config --modversion libosmocore command the version is reported as having value of UNKNOWN. I have also set the path of PKG_CONFIG_PATH correctly where the file libosmocore.pc is actually located but still this error is seen. checking if gcc supports -fvisibility=hidden... yes checking for pkg-config... /usr/bin/pkg-config checking pkg-config is at least version 0.9.0... yes checking for LIBOSMOCORE... no configure: error: Package requirements (libosmocore >= 0.3.0) were not met: Requested 'libosmocore >= 0.3.0' but version of Osmocom Core Library is UNKNOWN Consider adjusting the PKG_CONFIG_PATH environment variable if you installed software in a non-standard prefix. Alternatively, you may set the environment variables LIBOSMOCORE_CFLAGS and LIBOSMOCORE_LIBS to avoid the need to call pkg-config. See the pkg-config man page for more details. Please help me in this regard. Regards, Sarosh

[PATCH 1/3] logging: Implement subsecond resolution of extended timestamps
by Jacob Erlbeck 17 Mar '15

17 Mar '15

Currently when using 'logging print extended-timestamp 1', the subsecond part (milliseconds) of the printed timestamp is always 0. This makes it difficult to correlate log entries with PCAP file entries if there are many of them per second. This patch changes _output in logging.c to use gettimeofday() instead of time() when extended timestamps are enabled and replaces the '000' by the milliseconds computed from tv_usec.

AMR support in osmo-nitb
by Ciaby 11 Mar '15

11 Mar '15

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA512 Hi, I'm trying to get AMR to work (in TCH/F mode) on osmo-nitb. LCR is compiled with the correct codecs, but looking at the MNCC traffic I only get GSM FR coming from the osmo-nitb side. I already set this in osmo-nitb.cfg: mncc-int default-codec tch-f amr default-codec tch-h amr Any clue about this?
