I means: is the interaction with mtp3 layer implemented (is sending sccp data by mtp3 implemented by the library?)? Also, what about the reception of data from mtp3 layer. is that implemented in the sccp lib. I am asking these questions because I see the code of mtp3 in the lib but no significant call is present in the sccp part of the lib. Thank you for your help.

[PATCH 0/4] core/conv: Fast Viterbi decoding

by Thomas Tsou

Hi all, This patch set adds to libosmocore an optimized Viterbi decodeer for architecture specific (Intel SSE) and non-specific cases. The implementation covers codes with constraint lengths of K=5 and K=7 and rates 1/4 to 3/4, which make up the majority of GSM use cases. Speedup from the current implementation is in the range of 5 to 20 depending on the processor and code type. API is unchanged. Tested on Haswell (i7-4770K) and Atom (D2550). Additional test codes from osmo-bts are included. Further tests for AWGN bit-error-rate and benchmarks can be found in the following repository. https://github.com/ttsou/osmo-conv-test Here are some examples.

recurring issue with OpenBSC

by Ciaby

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA512 Hi! First a small update: we finally decided to _not_ use token mode, as it confuses a lot of phones, after receiving the token message the SIM goes into an error state and the only way to recover is to reboot the phone. Now we just read the IMSI straight from the SIM (using the card python library, just like osmo-sim-auth does) and register them. Now, the issue we see is that 1-2 users every day reach a point where they can make phone calls and send messages, but they can't receive neither of them. Sometimes the problem can be fixed by running: > subscriber extension <EXT> clear-requests but this only work when there are pending requests. In other cases, the phone has to be rebooted. Did anyone encounter the same issue?

Final review of L1SAP ported to current maste

by Harald Welte

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.

handover crash

by Holger Hans Peter Freyther

hi, this is a note. We had a crash with handover. So ho->new_lchan points to a "valid" lchan but ho->new_lchan->conn is NULL. Which means the new lchan failed/was freed/re-used.. but the "ho" entry wasn't killed. I thought I fixed such a bug recently but obviously no. Program terminated with signal 11, Segmentation fault. #0 0x00000000004078a7 in ho_T3103_cb (_ho=<optimized out>) at handover_logic.c:192 192 ho->new_lchan->conn->ho_lchan = NULL; (gdb) p

[PATCH] ipa: Declare all structs used

by Jacob Erlbeck

A few declarations are missing. This patch adds forward declarations for struct used for pointers only and an include directive (osmocom/core/select.h) to get a full definition of struct osmo_fd.

[PATCH 1/2] ipa: Add forward declaration of struct osmo_fd

by Jacob Erlbeck

A pointer to struct osmo_fd is used in a few prototypes declared in gsm/ipa.h, but is neither declared explicitly nor is such a declaration reachable via the given include directives. This patch adds a forward declaration of this type to ensure proper compilation.

[PATCH] ho: Copy the multirate config to the new lchan

by Holger Hans Peter Freyther

From: Holger Hans Peter Freyther <holger(a)moiji-mobile.com> The new lchan will be in speech mode already but for AMR we will need to provide a working multirate config in the channel activation, otherwise the channel act might be nacked. Copy the config from the current lchan into the new lchan. The abis code simply added the mrconf if the speech mode was amr. Before this commit the invalidate mrconf with all zeroes was copied/sent. --- openbsc/src/libbsc/handover_logic.c | 1 + 1 file changed, 1 insertion(+) diff --git a/openbsc/src/libbsc/handover_logic.c b/openbsc/src/libbsc/handover_logic.c index 9284f7e..ff6e993 100644 --- a/openbsc/src/libbsc/handover_logic.c +++ b/openbsc/src/libbsc/handover_logic.c @@ -133,6 +133,7 @@ int bsc_handover_start(struct gsm_lchan *old_lchan, struct gsm_bts *bts) new_lchan->bs_power = old_lchan->bs_power; new_lchan->rsl_cmode = old_lchan->rsl_cmode; new_lchan->tch_mode = old_lchan->tch_mode; + new_lchan->mr_conf = old_lchan->mr_conf; new_lchan->conn = old_lchan->conn; new_lchan->conn->ho_lchan = new_lchan; -- 2.1.3
