2016-08-30cosmetic: common ts_is_pdch()Neels Hofmeyr2-11/+16
Have one common ts_is_pdch(), placed in lchan.c, since this file is pretty empty and pretty close to ts. Publish in gsm_data.h. Remove the if-style implementation from l1sap.c, and instead implement in a switch statement. This prepares for upcoming ts_is_pdch() usage in ph_data_req() for sysmo and lc15.

2016-08-30dyn TS: measurement: use correct nr of subslots, rm code dupNeels Hofmeyr1-15/+1
In measurement.c, fix the number of sublots for TCH/F_TCH/H_PDCH, by using ts_subslots() from gsm_data_shared.c. The local dup of subslots_per_pchan[] is no longer needed. (depends on recent commit to openbsc.git for ts_sublots()) Change-Id: I9d9df470c49487bffd56dde42c7bec0da2f50642

Apply similar fixes as for TCH/F_PDCH also for TCH/F_TCH/H_PDCH: Detect dyn TS in PDCH mode in ts_is_pdch().

2016-08-08Fill measurements data for L1SAPMax3-4/+17
Fill in values for BER, BTO, Link quality in L1SAP and send them to PCU. Note: this increases the version of BTS <-> PCU protocol. It also requires corresponding changes in libosmocore. All BTS models provide measurements data unless direct DSP access for PCU is enabled. For BTS-specific notes see below. Octphy: conversion from sSNRDb to Link Quality uses formulae which works in practice instead of what's documented for sSNRDb value. Subject to change in future revisions. TRX: C / I link quality estimator is not computed. Change-Id: Ic9693a044756fb1c7bd2ff3cfa0db042c3c4e01c Related: OS#1616
2016-07-28dyn TS, dyn PDCH: common/l1sap.c: properly notice PDCHNeels Hofmeyr1-3/+11
In l1sap_ph_rts_ind(), l1sap_ph_data_ind() and to_gsmtap(), the decision to handle a TS as PDCH was still missing for dynamic TS. It is not yet clear why this did not impact functionality for dynamic timeslots on other BTS models. AFAICT they should not work without this patch, but in fact they do. It would be nice to clarify this some day. Change-Id: I7b873a089a3de70d980885a7539cb91997464743

2016-07-28trx: Enable EGPRS handling through burst lengthsTom Tsou1-11/+15
Existing interfaces are coded with the implicit expectation of using a burst sequence length of 148, which is constant with GSM and GPRS. That changes with EGPRS, where the burst length may be 444 due to the use of 8-PSK instead of GMSK modulation. Setup the interface to accept and return a length value with the burst sequence. This allows 444 length bit vectors to/from the EGPRS decoder/encoder. Length is explicitly used as a identifier for 8-PSK vs. GMSK modulated sequences.

2016-07-25dyn TS: common TCH/F_TCH/H_PDCH implementationNeels Hofmeyr4-12/+235
common/l1sap: For dyn TS, the BSC will issue RSL Chan Activ requests with a non-standard chan_nr. While the rest of the code now understands that, the L1 phy will not. Translate to standard PDCH (== TCH/F). common/oml: use dyn TS' current pchan mode for lchans config. common/pcu_sock: detect desired PDCH mode of dyn TS. common/rsl: implement reconnection chain of a TS for changing its pchan: * rsl_rx_chan_activ(): ** Add dyn_pchan_from_chan_nr() to derive the requested pchan from the RSL chan_nr IE. ** Notice the need for a pchan change and invoke dyn_ts_l1_reconnect() (s.b.) ** Make Chan Mode IE presence optional, because the non-standard PDCH activation message is simpler and does not require it. ** Do PDCH activation via PCU. * Add dyn_ts_l1_reconnect(): store state and disconnect the L1 channel; then wait for cb_ts_disconnected(). * Add osmo_dyn_ts_disconnected() to cb_ts_disconnected(): verify state and connect with the new pchan type; then wait for cb_ts_connected(). * Add osmo_dyn_ts_connected() to cb_ts_connected(), which re-issues the cached chan activation message from before disconnecting the L1 channel. * Also send an rf chan rel/act ack for dyn TS upon PDCH de/act via PCU. * Add dyn_ts_pdch_release(): on channel release of a dyn TS in PDCH mode, release via the PCU. Call from rsl_rx_rd_chan_rel(). Change-Id: I463bb6b4e57674f091c3badba9257374961c52c7
2016-07-25code dup: join [rsl_]lchan_lookup() from libbsc and osmo-btsNeels Hofmeyr1-52/+12
lchan_lookup in openbsc abis_rsl.c and rsl_lchan_lookup() rsl.c are the same code, except for the log context, which is only set in abis_rsl.c. The common code was factored out to gsm_data_shared.c in openbsc.git. Use the *rc return code argument to keep the logging part in the newly introduced thin wrapper lchan_lookup() in common/rsl.c. This also removes code dup for logging The rsl_lchan_lookup() implementation is removed from osmo-bts, so a recent openbsc is needed to build this.

2016-07-25prepare dyn TS: split/replace conf_lchans_for_pchan()Neels Hofmeyr1-4/+11
Move the actual switch from static conf_lchans_for_pchan() into new 'public' function conf_lchans_as_pchan(), adding an explicit pchan argument. This allows passing a non-trivial pchan, for dynamic TS. conf_lchans_as_pchan() now takes a pchan argument, so distinguish the naming and drop the 'for_pchan' from conf_lchans_for_pchan(), which takes only a ts argument.

2016-07-25cosmetic: clarify TCH/F_PDCH related naming and commentsNeels Hofmeyr3-22/+38
We're about to introduce a new kind of dynamic channel, which will also use parts of the ip.access mode dyn PDCH code paths. Make sure the general parts have general names and mark ip.access specific parts as such. Rename dyn_pdch_ts_[dis]connected() to cb_ts_[dis]connected(). Rename dyn_pdch_complete to ipacc_dyn_pdch_complete(). From cb_ts_[dis]connected(), factor out the current code into static functions ipacc_dyn_pdch_[dis]connected() -- this will make sense once the new dynamic kind is added to cb_ts_[dis]connected().

2016-06-17dyn PDCH: implement main dyn PDCH logic in common/Neels Hofmeyr2-0/+280
React on IPAC PDCH ACT and DEACT messages and invoke the PCU and bts_model_ts_* APIs to effect switchover. The dyn PDCH interaction is described in the comment to rsl_rx_dyn_pdch(), the main entry point for PDCH switchover. In case the bts_model_ts_* are not implemented (or return other errors), reply with an IPAC PDCH ACT/DEACT NACK. Add callbacks that mark steps in the PDCH switchover process, dyn_pdch_ts_disconnected(), dyn_pdch_ts_connected() and dyn_pdch_complete(). Add hooks in l1sap.c on channel activation and release confirmation, to call dyn PDCH callbacks. BTS dyn PDCH implementations should invoke dyn_pdch_ts_disconnected() and dyn_pdch_ts_connected() when bts_model_ts_disconnect() or bts_model_ts_connect() are called, respectively.
