2018-09-03gsm48_parse_meas_rep(): set num_cell=0 if no neighbor cells are reportedNeels Hofmeyr1-1/+4
Set mr->num_cell to 0 if the bits reflect 0x7, which means that no neighbor cell measurements are enclosed in the report. The code in gsm48_parse_meas_rep() acknowledges that, but nevertheless left num_cell == 7, and evaluating code commonly runs into the mistake of assuming that actually seven neighbors are being reported on, like: MEASUREMENT REPORT 0: arfcn=0 bsic=0 neigh_idx=0 rxlev=0 flags=0 1: arfcn=0 bsic=0 neigh_idx=0 rxlev=0 flags=0 2: arfcn=0 bsic=0 neigh_idx=0 rxlev=0 flags=0 3: arfcn=0 bsic=0 neigh_idx=0 rxlev=0 flags=0 4: arfcn=0 bsic=0 neigh_idx=0 rxlev=0 flags=0 5: arfcn=0 bsic=0 neigh_idx=0 rxlev=0 flags=0 6: arfcn=0 bsic=0 neigh_idx=0 rxlev=0 flags=0 There are only up to 6 slots for neighbors, the above listing actually printed 7, because num_cell == 7, which is a potential segfault. (sometimes it printed uninitialized values instead of 0) We could fix all meas rep consumers to know what num_cell == 7 means, but instead setting it to 0 trivially fixes all of them.

2018-09-03HO: Count neighbor measurements and reduce window of neigh_meas_avgAndreas Eversberg1-0/+8
Always start with a counter of 0 for a new measurement report. If the neigh_meas_avg is caluclated over the given window, the window is reduced, if there are less measurement reports received so far. Change-Id: If476838dc14729b894693f371e181ac657b84017

2018-05-21sms charging: Implement SMS online ECUR charging based on 3GPP TS 32.274Ivan Klyuchnikov4-32/+378
Event Charging with Unit Reservation (ECUR) principle is used for SMS online charging in osmo-nitb. Osmo-nitb generates Reserve Units information which is transferred to OCS. For this purpose, osmo-nitb utilizes the Reserve Units procedure that is specified in TS 32.274 and TS 32.299. The Reserve Units procedure employs the Reserve Units Request and Reserve Units Response messages. Change-Id: I12b681f65cdcdb281da04b49a63ceb140be7e643
2018-05-21sms charging: Add socket for connection to OCS for sms chargingIvan Klyuchnikov2-0/+27
We use implementation of gsup client for this connection, but it makes sense to implement a separate client for these types of connection. Change-Id: I5089c2b68fd8c67dd838290256e677c213416d46

2017-08-23handover: Implement proper handover procedure handling at any stage of the callIvan Kluchnikov5-82/+199
Enhancements for each stage of handover procedure should be implemented in order to support handover at any stage of the call. For these purposes new in_handover state and ho_queue for call control messages was introduced for gsm_subscriber_connection. Stage 1: HO-Command is sent to MS gsm_subscriber_connection state should be changed to in_handover=1. In this state all transmission of signalling layer messages (except RR messages needed for handover procedure) should be suspended until resuming is indicated. All call control messages for connection received from network side should be buffered in ho_queue. All call control messages for connection received from MS side should be ignored. Channel mode modification procedures should be also suspended. Stage 2: HO-Detect is received from MS Audio path should be switched on network side. Stage 3-1: HO-Complete is received from MS Resumption procedure after successful handover should be performed: - gsm_subscriber_connection state should be changed to normal (in_handover=0). - all buffered call control messages (ho_queue) should be sent to MS on new lchan. - suspended channel mode modification procedures should be performed on new lchan. Stage 3-2: HO-Fail is received from MS Resumption procedure after failed handover should be performed: - gsm_subscriber_connection state should be changed to normal (in_handover=0). - all buffered call control messages (ho_queue) should be sent to MS on old lchan. - suspended channel mode modification procedures should be performed on old lchan. Stage 3-3: T3103 expired: Handover has failed without HO-Complete or HO-Fail Resumption procedure should not be performed in case of T3103 expired: - gsm_subscriber_connection state should be changed to normal (in_handover=0). - all buffered call control messages (ho_queue) should be cleaned without sending them to MS. - suspended channel mode modification procedures should not be performed.

2017-08-23transaction: Add new function trans_find_by_lchanIvan Kluchnikov2-0/+27
Function returns transaction for given lchan. In case of active call hold procedure it could be two transactions in a list with links to the same lchan: * transaction for call on hold * transaction for active call. In this case function ignores transaction which was put on hold and returns active call transaction. Change-Id: I41171d4e61abfa5f2b01d6fbf4a0ac98073d97a9

2017-08-23handover_decision: Fix condition for power budget handover attemptIvan Kluchnikov1-1/+1
Handover attempt for power budget case should be performed every N SACCH frames, where N = Power Budget Interval. First measurement report with mr->nr = 0 was used for the first handover attempt in this case, which is not correct, because first usable report should have mr->nr = net->handover.pwr_interval-1. Moreover using the first measurement report with mr->nr = 0 for handover attempt could lead to unnecessary handover, because usually av_rxlev for first measurement report from MS is worse than for following reports.

2017-08-10handover_logic: set correct link to bts for subscriber_connection in case of ↵Ivan Kluchnikov1-0/+1
moving this connection to another bts In case of successful completion of handover gsm_subscriber_connection could be moved from one bts to another, so connection link to bts should be replaced by link to bts, which owns new_lchan. This bug was detected, because conn->bts->nr is used in call control log messages and wrong number of bts was observed in these messages after handover.

2017-07-19gsm_04_08: Implement support of placing an existing call on hold when ↵Ivan Kluchnikov1-0/+4
another call comes in and switching to new call In this case two transactions with links to the same lchan are in transaction list: * transaction for call on hold * transaction for active call. New condition was added for searching function to avoid selecting transaction which was put on hold and use active call transaction for rtp handling and handover procedures.

2017-07-11libcommon: Fix log output for bts>0.Alexander Chemeris5-9/+11
Fixes regression probably introduced in c696cc28. For bts>0 logging doesn't show bts number correctly when printing lchan identification string - it will always show it as "bts=0". The reason for this is that the identification string is cached before bts->nr value is set to a proper value. This patch sets bts->nr as part of the first step of the bts structure initialization, before caching happens thus making sure the cached identification string is cached with the correct values.

* Introduced mncc message with type MNCC_RTP_MODIFY for forwarding modified rtp info to external application. * Added handler for HANDOVER_DETECT signal, which forwards rtp info (modified during handover process) to external application via mncc.
