2019-12-31osmo-bts-trx/vty: ensure backwards compatibility with older config filesVadim Yanitskiy1-2/+11
osmo-bts-trx used to have its own (low-level) MS Power Control loop, but recently it has been ripped out. Since [1], the process fails to start if the configuration file still contains 'ms-power-control dsp'. Let's be more tolerant: override 'dsp' by 'osmo' and print a warning.

2019-11-14Introduce BTS feature BTS_FEAT_MS_PWR_CTRL_DSPPau Espin Pedrol1-1/+7
It indicates whether BTS model supports managing an MS Power Control Loop over HW/DSP instead of using the software based osmocom algorithm present in osmo-bts. osmo-bts-trx own loop implementation is considered to be a "DSP/HW" one since it acts on lower layers and interferes with osmocom algorithm since it controls the same end variable "lchan->ms_power_ctrl.current", this way we make sure both aren't enabled at the same time. Old behavior in kept: if common upper-layer algo is not enabled explicitly in VTY (ms-power-control osmo) and bts-trx specific lower layer algo is neither enabled (osmotrx ms-power-loop <xyz>), then no power control is done at all.

2019-11-14Move and rename gsm_lchan.ms_power fieldPau Espin Pedrol1-1/+1
Make it clear that it contains the maximum MS power level (TS 05.05) and not the one to be used. The one aimed at is in ms_power_ctrl.current. Since it's used in related code, move it inside the ms_power_ctrl struct too. Related: OS#1851 Change-Id: Ib264ec7dac87355cef6415461ed74bd8e9c8ca52

Thies field is used to store and retrieve whether MS power needs to be calculated and updated by osmo-bts software or autonomously by lower layers. Previous name was not clear and may have been understood as indicating whether MS Power Control loop is done or not in general, and the responsible for that is located under lchan's ms_power_ctrl.fixed.

2019-08-05Remove undefined param passed to {logging,osmo_stats}_vty_add_cmdsPau Espin Pedrol1-2/+2
Since March 15th 2017, libosmocore API logging_vty_add_cmds() had its parameter removed (c65c5b4ea075ef6cef11fff9442ae0b15c1d6af7). However, definition in C file doesn't contain "(void)", which means number of parameters is undefined and thus compiler doesn't complain. Let's remove parameters from all callers before enforcing "(void)" on it. API osmo_stats_vty_add_cmds never had a param list but has seem problem (no "void"), so some users decided to pass a parameter to it.

2019-07-21Clarify and refactor link quality (C/I) handlingVadim Yanitskiy1-8/+8
The radio link quality is defined by C/I (Carrier-to-Interference ratio), which is computed from the training sequence of each received burst, by comparing the "ideal" training sequence with the actual (received) one. Link quality measurements are used by L1SAP to filter out "ghost" Access Bursts, and by the link quality adaptation algorithms. One can define minimum link quality values using the VTY interface. On the VTY interface we expect integer C/I values in centiBels (cB, 10e-2 B), while the internal structures are using float values in deciBels (dB, 10e-1 B). Some PHYs (sysmo, octphy, oc2g, and litecell15) expose C/I measurements in deciBels, while on the L1SAP interface we finally send then in centiBels. Let's avoid this confusion and stick to a single format, that will be used by the internal logic of OsmoBTS - integer values (int16_t) in centiBels. This will give us the range of: -32768 .. 32767 centiBels, or -3276.8 .. 3276.7 deciBels, which is certainly sufficient. Change-Id: If624d6fdc0270e6813af8700d95f1345903c8a01

Let's keep some statistics about the min/max/average frame number advance that we're observing above L1SAP when comparing the time in the PH-RTS.ind and the frame number we observe in PH-DATA.ind of data that was received on the uplink. The statistics are currently only shown in the VTY, but this is a precursor to using them to correctly advance the LAPDm timers in a follow-up patch.

2018-11-21bts: Fix TRX0 param initializationPau Espin Pedrol1-1/+4
TRX0 is allocated in a different place than other TRX. Commit that introduced the bug added an initialization step (bts_trx_init) applied in VTY cmd "trx <0-254>", where TRX are allocated since same commit, but doesn't initialize TRX0 for reasons explained in first paragraph. As a result, some parameters were not applied to TRX0, like power ramping increment step, which prevented MS from finding the network in osmo-gsm-tester tests.

2018-11-18bts: Allocate TRX for BTS dynamically, deprecate -tPau Espin Pedrol1-5/+15
No need to pass -t num_trx anymore to specify number of TRX to use. It is calculated based on dynamic allocation from VTY config. Using parameter -t is flagged as deprecated and is transformed into a NOOP por backward compatibility. As a result, TRX now are allocated after the BTS is allocated and initial config (pre-VTY) is applied. A new function bts_trx_init() is added, to set default config on each TRX during allocation and before setting VTY config on it. A new per BTS model function bts_model_trx_init() is added, to allow per model specific default configuration of each TRX. Change-Id: Iab1a754ab12a626759f9f90aa66f87bdce65ac9c

2018-05-25rtp: make port range configurable, assign correct port numbersPhilipp Maier1-0/+40
The current implementation does not allow the user to specify a port range in which the BTS is allowed to allocate a local RTP port. Also the ports the BTS picks do not match the policy described in RFC3550. An RTP Port must be at an even port number and the matching RTCP port must be at the following (odd) port number. The BTS currently picks random port numbers for both. - Add a VTY command to specify a port range in which the BTS may assign local ports. - Pick ports as described in RFC3550.

gsm_bts_role_bts was introduced at a time when we still shared gsm_data_shared.[ch] between BSC and BTS, and where we then subsequently needed a BTS-private structure.

2018-02-27Add high-accuracy ToA value to Uplink Measurement ReportsHarald Welte1-0/+28
Normal Abis RSL MEasurement Results contain only the "MS Timing Offset IE" in units of full symbols. In some use cases it is important to have higher-accuracy timing information exposed to the BSC. We do this by adding the average timing offset value during the last measurement interval in 1/256th symbol accuracy to the "Supplementary MEasuremen Information" part of the TS 48.058 9.3.25 Uplink Measurements IE. In order to avoid any compatibility issues, this feature is only enabled if the new vty config command "supp-meas-info toa256" at the bts node is enabled.

2018-02-27RACH decoding: Use BER threshold for RACH ghost detectionHarald Welte1-0/+16
When decoding RACH bursts, we should use a BER threshold in order to help distinguish 'ghost' RACH bursts from real RACH bursts. The theoretical ideal threshold according to some papers is 7 out of 41 bits qhich aquals to Eb/N0 of 0 dB = 0.1707 (17.07%) We add a new 'ber10k' parameter to the RACH indication l1sap primitive (needs separate change for libosmocore), and then fill this value from osmo-bts-{sysmo,lc15,trx,octphy}. The common part above L1SAP then applies the threshold, which can be changed from vty using the "max-ber10k-rach <0-10000>" command available at the BTS node. The unit is BER in 1/10000, i.e. a value of 100 equals 1% bit error rate. Change-Id: Ic41c11f6312a36baa2738547e8dcec80829457f8

2017-05-29vty: Remove command for manual channel activation/deactivationHarald Welte1-60/+0
OsmoBTS won't run without being connected to a BSC. The BTS wouldn't start to transmit if the BSC doesn't properly initialize it. So if we want to activate some channels manually for testing, we should do so from the BSC, and not inside the BTS code. Doing this in the BTS means that the BSC is not aware of it and might want to use that channel for something else meanwhile. Osmo{BSC,NITB} has gained ability to manually activate a channel from the VTY in Change-Id I44fc3904678eb48bd3ab1a3da8c0c265fa082e0d as can be seen at https://gerrit.osmocom.org/2759 So let's remove the old/obsoleted code here.

2017-02-10all models: fix vty write: bts_model_config_write_phyNeels Hofmeyr1-0/+1
The vty write for phy/inst is broken, leading to a written-out config being unparsable; fix all of these: - in common/vty.c, actually call bts_model_config_write_phy_inst(). - in sysmo and lc15 write the phy instance elements in bts_model_config_write_phy_inst() and not in bts_model_config_write_phy(), which lead to writing the members above their parent 'instance'. - sysmo, lc15 and oct omit the bts_model_config_write_phy_inst() implementation. This did not cause a compilation problem because it was in fact never called. - sysmo writes 'clock-source None' when clk_src is zero, leading to unparsable config (related: OS#1944). Instead omit the 'clock-source' when zero. - osmo-bts-trx seems to be the only part that lacks nothing, yet it also didn't work properly because bts_model_config_write_phy_inst() was never called.

This is the easiest way I found to make BTS level loopback to work. Another way to implement this is to have BSC/NITB to send the OML command, but it's a longer path with no clear benefits. Note, that the current code hardcodes the channel to be TCH/F with v1 speech, which is what we need for the basic BER testing. We may want to extend this later to support more channel types.
