2012-02-03abis_rsl.c: Remove unused variable net.Holger Hans Peter Freyther1-2/+0
The old BSC code had code to override the payload type, this has been removed, remove the variable accessing it. GCC warning: abis_rsl.c: In function ‘ipa_rtp_pt_for_lchan’: abis_rsl.c:1590:22: warning: unused variable ‘net’ [-Wunused-variable]
2012-02-03abis_rsl: The rach information was not used, introduce a signalHolger Hans Peter Freyther1-12/+16
Introduce a SS_CCCH for the paging and the rach load. The paging code could now start using the signal. GCC warning: abis_rsl.c: In function ‘rsl_rx_ccch_load’: abis_rsl.c:1371:11: warning: variable ‘rach_access_count’ set but not used [-Wunused-but-set-variable] abis_rsl.c:1370:11: warning: variable ‘rach_busy_count’ set but not used [-Wunused-but-set-variable] abis_rsl.c:1369:11: warning: variable ‘rach_slot_count’ set but not used [-Wunused-but-set-variable]
2012-02-03abis_rsl.c: Remove unused variable ts_numberHolger Hans Peter Freyther1-2/+1
GCC warning: abis_rsl.c: In function ‘rsl_rx_chan_rqd’: abis_rsl.c:1245:10: warning: variable ‘ts_number’ set but not used [-Wunused-but-set-variable]
2012-01-15channel: Review lchan_free calls and the state the channel is inHolger Hans Peter Freyther1-1/+1
In case of a memory allocation failure in rsl_rx_chan_rqd we would have left the channel in the LCHAN_S_ACT_REQ state. Move the state change below the allocation.
2012-01-15channel: The error timer and the lchan_deact_tmr are both runningHolger Hans Peter Freyther1-1/+2
In case a BTS does not send the RF Channel Release ACK and we are closing the channel because of an error two timers are running to set the state back to none. Make lchan_deact_tmr_cb and rsl_rx_rf_chan_rel_ack behave the same in regard to changing the state of the lchan. For the other direction we are save, the error path will set the state to NONE and the timeout will call lchan_free to set the channel type back to NONE, only then the lchan may be allocated again. The channel release procedure requires some more tweaking, some part was started in the zecke/28c3 branch and needs to be tested/integrated with the goal of having one common release path.

2011-08-22audio: From RTP point of view we can use one payload for HR/FR AMRHolger Hans Peter Freyther1-2/+1
Remove the separation of half-rate and full-rate AMR. The used rate can be found inside the AMR payload. The signalling of what kind of traffic channel is used can be done with the GSM 08.08 Chosen Channel IE in the Assignment Complete message. This way I can use a fixed payload type in the MGCP GateWay but have a mixed TCH/F and TCH/H config. E.g. use TCH/F FR3 for some subscribers when connected to MSC A but use AMR5.9 on a TCH/F for MSC B when all TCH/Hs are gone.
2011-08-22audio: Remove the hardcoding of the RTP PayloadHolger Hans Peter Freyther1-4/+0
The MGCP config must be correct and use 99 for RTP AMR.
2011-08-19src: port openBSC over libosmo-abis0.9.15Pablo Neira Ayuso1-1/+1
This is a big patch that ports openBSC over libosmo-abis. Sorry, the changes that are included here are all dependent of libosmo-abis, splitting them into smaller pieces would leave the repository in some intermediate state, which is not desired. The main changes are: - The directory libabis/ has been removed as it now lives in libosmo-abis. - new configuration file format for nanoBTS and HSL femto, we need to define the virtual e1_line and attach it to the OML link. - all the existing BTS drivers (nanoBTS, hsl femto, Nokia site, BS11 and rbs2000) now use the new libosmo-abis framework. - use r232 input driver available in libosmo-abis for bs11_config. - use ipa_msg_recv instead of old ipaccess_read_msg function. - delete definition of gsm_e1_subslot and input_signal_data. These structures now lives in libosmo-abis. Most of this patch are deletions of libabis/ which has been moved to libosmo-abis. This patch also modifies openBSC to use all the new definitions available in libosmocore and libosmo-abis. In order to do that, we have replaced the following: - DINP, DMI, DMIB and DMUX by their respective DL* correspondences. - SS_GLOBAL by SS_L_GLOBAL - SS_INPUT by SS_L_INPUT - S_GLOBAL_SHUTDOWN by S_L_GLOBAL_SHUTDOWN - SS_INPUT by SS_L_INPUT - S_INP_* by S_L_INP_* sub-signals - E1INP_NODE by L_E1INP_NODE vty node This patch has been tested with: - one nanoBTS - the HSL femto with the examples available under libosmo-abis - BS11 with both dahdi and misdn drivers.
2011-08-19src: use new msg->dst pointer instead of deprecated msg->trxPablo Neira Ayuso1-38/+50
This patch modifies openBSC code to use msg->dst which stores the pointer to the signalling link structure instead of the pointer to the transceiver structure. This patch prepares the introduction of libosmo-abis.
2011-08-11libbsc: Cosmetic fix for the channel activate NACK log messageDaniel Willmann1-1/+1
2011-08-11libbsc: Release the RF channel if BTS thinks it's still in useDaniel Willmann1-0/+3
The Nokia metrosite BTS seem to keep the channels open indefinitely. If osmo-nitb is restarted while one of the channel was still active and tries to activate that channel again the bts would return a CHANNEL ACTIVATE NACK with "Radio channel already activated". This accumulated over the restarts so soon enough no more channels were available. This patch sends a release request to the bts so the channel becomes available again.
2011-08-11libbsc: Call lchan_free in the timeout callbacksDaniel Willmann1-2/+4
This makes sure that the lchans can be used again. (state and type are set to NONE)
2011-08-11RSL: add timer for lchan activation/deactivation without BTS responseHarald Welte1-1/+37
The timer callback will simply reset the lchan state to NONE in order to prevent channels getting stuck in 'activation requested' or 'deactivation requested' states.
2011-08-10Initial version of Support for Nokia *Site BTSDieter Spaar1-0/+53
This includes the MetroSite, but also other Nokia BTS models.
2011-07-27RSL: Fix erroneous GSM48_IE_CHANDESC_2 in rsl_chan_activate_lchan()Dieter Spaar1-1/+1
This fixes a bug introduced more than one year ago in commit e38bd6caa34005816a9336f021fd17d328d5c901: The RSL_IE_CHAN_IDENT is a TLV, but the GSM48_IE_CHANDESC_2 contained in it, is a mere TV type IE with fixed length. The problem specifically has caused problems on Nokia MetroSite BTS, which apparently read the TSC out of this Layer3 IE.

2011-04-18misc: Remove sys/types.h includes from the filesHolger Hans Peter Freyther1-1/+0
These are not needed any more. We used them for u_int types but we now use uint which comes from stdint.h
2011-04-18misc: Move from u_int to uint types of stdint.hHolger Hans Peter Freyther1-83/+83
This was done with sed on the files.
2011-03-23src: use new library libosmogsm and new path to headers in libosmocorePablo Neira Ayuso1-4/+4
libosmogsm is a new library that is distributed in the libosmocore. Now, openbsc depends on it. This patch gets openbsc with this change. This patch also rewrites all include path to the new osmocom/[gsm|core] Signed-off-by: Pablo Neira Ayuso <pablo@gnumonks.org>
2011-03-04Implement the HSL SR1.0.1 protocolHarald Welte1-1/+2
It seems HSL has fixed most of their obvious issues in the SR1.0.1 release. However, this creates quite an incompatibility of the protocol, and we have to adapt accordingly
2011-03-04[HSL] initial support for the HSL 2.75G FemtocellHarald Welte1-1/+11
The HSL Femtocell seems to be a poor man implementation of the ip.access Abis/IP protocol, but cutting corners wherever possible. We try to workaround those corners wherever possible...
