2014-05-19Revert "sysmobts: Add support for changing the transmit power in sbts2050"Harald Welte5-231/+11
This reverts commit c64d42573894d8295b58b268a64541c914b69bcd. There are unfrtunately still too many problems with this patch to be merged at this point.
2014-05-18sysmoBTS TCH: Set CMR in AMR RTP framesHarald Welte1-12/+7
Enable the previously commented-out logic to set the CMR (Codec Mode Request) in AMR RTP frames based on the CMI (CMR Index) of the AMR speech frame on the Um interface. This is of course anyway the right thing to do, but also required for an AMR receiver which doesn't have out-of-band information on the codec mode, and which also doesn't determine the AMR codec mode based on the size of the AMR frame (such as lcr as of current master). We also move the entire CMR generation into the #ifdef section which is only compiled-in if we do _not_ use the RTP mode of L1.
2014-05-18sysmobts: Add support for changing the transmit power in sbts2050Álvaro Neira Ayuso5-11/+231
Make the sysmobts-mgr send a manufacturer O&M message with the power reduction we want the sysmobts to apply. The sysmobts will handle this message and set the new tx output power. An ACK/NACK will be send as a response to the power reduction. Signed-off-by: Alvaro Neira Ayuso <anayuso@sysmocom.de>
2014-05-18sysmobts-mgr: Add VTY support for configuring itÁlvaro Neira Ayuso4-3/+342
This patch allows to configure the warning temperature threshold, the severe temperature threshold of the board and the PA and the actions like the relative value power that we want to reduce the transmit power to and the part that we want to switch off or not.

2014-05-15abis: Separate initialization from connect for AbisHolger Hans Peter Freyther2-12/+13
Initialize the libosmo-abis VTY nodes more early so we can parse the config file that was created by "write". Introduce abis_init to initialize the libosmo-abis and modify abis_open to re-use an existing line. Update the comments. This has only been tried with the sysmobts-remote on x86. A TCP connection is opened toward the configured BSC. Fixes: SYS#285

2014-04-19handover: Call the right function and avoid recursionHolger Hans Peter Freyther1-1/+1
Fix a brown paper bag bug and call the right method. The above was an infinite recursion. The stack didn't overflow as the compiler optimized the tail-recursion and coverity didn't complain either. The issue was introduced in the last minutes before the merge when I renamed "reset_handover" to "handover_reset" to follow the object_verb approach throughout the handover.c code. While doing that I sadly replaced reset_handover with handover_frame and not handover_reset.

2014-04-03oml: Pass all valid state change requests to the modelJacob Erlbeck1-5/+4
Currently ADM state change request that tries to set the administrative state to the current value are immediately ACK'ed. Beside the caching problem, this could lead the protocol inconsistencies if two such requests are sent one after the other and the second arrives before the procedure of the first has finished. This patch removes the shortcut in oml_rx_chg_adm_state() which immediately called oml_mo_statechg_ack(mo). Ticket: OW#1132 Sponsored-by: On-Waves ehf

2014-03-27agch/pcu: Fix crash for AGCH commands queued by the PCUHolger Hans Peter Freyther1-1/+2
The dequeue code assumed that msg->l3h is a valid pointer but in the case of the PCU socket it was a null pointer. This lead to memcpy copying a lot more than 23 bytes which ultimately lead to a crash. The issue was introduced in the git commits 37c332e5bfdb9591a1cd3cc6746afffdb1cd13b9 and the commit d290ee029a827c870f97372b98f0dbd7d057402a. use msg->l3h = msgb_put(msg, len) to make sure that there is a valid L3 pointer for the message.

2014-03-26sysmobts: Apply the potentially new max_power_red on the TRXHolger Hans Peter Freyther1-0/+9
In case the max power reduction has been changed through OML, let us call the l1if_set_txpower routine to update the nominal power. This has been manually verified with both BTS #1 and #57. ./bsc_control.py -d localhost -p 4249 -s bts.0.trx.0.max-power-reduction 0 The above command and GNUradio have been used to determine if the power level has changed at all. Fixes: SYS#268
2014-03-26oml: Indicate the kind of object passed as the void*Holger Hans Peter Freyther2-4/+4
These routines do not pass the gsm_abis_mo and parsing the FOM header of the msg does not seem to be a good idea either. Pass in the OML object so that the model code can determine what the void pointer is.
2014-03-26sysmobts: Honor power reduction on older sysmoBTSv2 hardwareHolger Hans Peter Freyther2-7/+25
Older hardware didn't have the external attentuator that was used to control the wanted output power. So starting from the git commit 3c8ff3c70bc52d0a1d75a1e6b87b0069d92f10f9 older hardware was always transmitting with 23 dBm regardless of the power reduction. Remember the hardware revision returned by the SystemInformation primitive, postpone the call to l1if_activate_rf until we know the board revision. Manually verified on BTS #1 and #57. On BTS#1 the external attenuator has not been configured and on BTS#57 it was.

2014-03-16sysmobts: Add a magic number to the hLayer2 to differentiate itHolger Hans Peter Freyther1-1/+8
The DSP/FPGA appears to report bogus PhDataInd with hlayer2 == 0. Currently this would match the TRX==0,TS==0 and SS=0 and then we report bad measurement reports. Add a magic number to the lower eight bit of the hLayer2 to differentiate valid numbers. Addresses: <0004> measurement.c:97 (bts=0,trx=0,ts=0,ss=0) measurement during state: NONE <0004> measurement.c:102 (bts=0,trx=0,ts=0,ss=0) no space for uplink measurement

2014-03-10handover,sysmobts: Handle handover in the sysmobts codeHolger Hans Peter Freyther2-2/+77
When the lchan was activated for handover configure it to wait for a RACH burst. On release make sure to always release the RACH SAPI (in case it has been allocated). On the first frame inform handover.c about it and forward the received access burst to the handover layer. Using an E71 it was possible to make a handover for SDCCH and TCH/F from a nanoBTS but also from itself to itself. The vty commands of OpenBSC and the silent-call have been used for that. I didn't verify audio handling so far.

2014-03-10handover: Add generic handling for handoverAndreas Eversberg2-0/+121
The BTS layer needs to inform the handover code when an access burst has been received. In turn the handover layer will ask the bts to modify the channel, it will schedule the physical information inform the BSC with the HANDOVER DETECTION and waits for the BTS layer to inform it about the first received frame to stop a timer.

2014-03-10agch: Merge IMM.ASS.REJ if possible when enqueueingJacob Erlbeck1-0/+140
This patch implements merging of IMMEDIATE ASSIGN REJECT messages as suggested in GSM 08.58, 5.7. When a new IMM.ASS.REJ is to be appended to the AGCH queue and the last message in that queue is of the same type, the individual entries (up to 4 per message) of both messages are extracted, combined and stored back. If there are less than 5 entries, all entries fit into the old message and the new one is discarded. Otherwise, the old message will contain 4 entries and the remaining ones are stored into the new one which is then appended to the queue. Ticket: SYS#224 Sponsored-by: On-Waves ehf
2014-03-10agch: Add VTY queue management configurationJacob Erlbeck1-0/+43
This patch adds the following VTY commands to tune AGCH queue handling: agch-queue-management default agch-queue-management threshold THRES low LOW high HIGH Examples: agch-queue-management default Resets queue management to default parameters. agch-queue-management threshold 0 low 25 high 75 Start dropping at 25%, drop all messages above 75% queue length (relative to max queue length corresponding to T3126). Between low and high, drop with a probability interpolated linearly between 0 (low) and 1 (high). agch-queue-management threshold 50 low 0 high 0 Start dropping at 50% and continue until all IMM.ASS.REJ have been removed from the front (output) of the queue Sponsored-by: On-Waves ehf
2014-03-10agch: Manage AGCH queue lengthJacob Erlbeck1-9/+98
Currently, the AGCH queue length is not limited. This can lead to large delays and network malfunction if there are many IMM.ASS.REJ messages. This patch adds two features: - Don't accept msgs from the RSL layer when the queue is way too full (safety measure, mainly if bts_ccch_copy_msg() is not being called by the L1 layer, currently hard coded to 1000 messages) - Selectively drop IMM.ASS.REJ from the queue output depending on the queue length Ticket: SYS#224 Sponsored-by: On-Waves ehf
2014-03-10agch/pch: Use PCH for AGCH msgsJacob Erlbeck2-4/+16
This patch extends paging_gen_msg() by adding an output parameter is_empty that is true, if only a paging message with dummy entries has been placed into buffer. This feature is then used by bts_ccch_copy_msg() to insert an AGCH message if is_empty is true. Ticket: SYS#224 Sponsored-by: On-Waves ehf
2014-03-10agch: Add simple countersJacob Erlbeck2-0/+9
Counters are added for the following events (use VTY show to query): - Dropped IMMEDIATE ASSIGN REJECT messages - Merged IMMEDIATE ASSIGN REJECT messages - Rejected AGCH messages - Use of PCH (non-reserved) for AGCH messages - Use of AGCH (reserved) for AGCH messages Sponsored-by: On-Waves ehf
2014-03-10agch: Recalculate length limit of AGCH queueJacob Erlbeck1-1/+89
This patch adds a function bts_update_agch_max_queue_length() to compute a limit of the AGCH queue. This is based on the idea, that the AGCH queue has a limited drain rate and that CHANNEL REQUESTs must be answered within a certain time frame, given by the minimum value of T3126 (see GSM 04.08). When the AGCH queue reaches that limit, the last message would be delivered in time if there were no other delays involved (which is not the case). The calculation is based on the ratio of the number RACH slots and CCCH blocks per time: Lmax = (T + 2*S) / R_RACH * R_CCCH where T3126_min = (T + 2*S) / R_RACH R_RACH is the RACH slot rate (e.g. RACHs per multiframe) R_CCCH is the CCCH block rate (same time base like R_RACH) The value depends control_channel_desc.ccch_conf and rach_control.tx_integer (both from SYSINFO_TYPE_3) and should therefore by called at least each time after one of these is changed. For this reason, a signal callback is registered under SS_GLOBAL/S_NEW_SYSINFO which invokes bts_update_agch_max_queue_length().
