That is to say, the old revision is not a strict subset of the new revision. This situation occurs when you --force push a change and generate a repository containing something like this: * -- * -- B -- O -- O -- O (6f9d51e2782ce349aac10278620fa8f47c091ac8) \ N -- N -- N (d3350c8cd2aa6a32a65fd0ea1691db16e662592e) When this happens we assume that you've already had alert emails for all of the O revisions, and so we here report only the revisions in the N branch from the common base, B. Those revisions listed above that are new to this repository have not appeared on any other notification email; so we list those revisions in full, below. - Log ----------------------------------------------------------------- http://cgit.osmocom.org/osmo-pcu/commit/?id=d3350c8cd2aa6a32a65fd0ea1691db16e662592e commit d3350c8cd2aa6a32a65fd0ea1691db16e662592e Author: Jacob Erlbeck <jerlbeck at sysmocom.de> Date: Fri Jun 5 16:33:33 2015 +0200 vty: Add command to show detailed MS info This commit extends the "show ms" command to display an extended set of information for a single MS. The following VTY commands are added: - show ms tlli TLLI - show ms imsi IMSI Sponsored-by: On-Waves ehf http://cgit.osmocom.org/osmo-pcu/commit/?id=5bf5b0da30700bb881295794ad6ea1edf0d854d3 commit 5bf5b0da30700bb881295794ad6ea1edf0d854d3 Author: Jacob Erlbeck <jerlbeck at sysmocom.de> Date: Thu Jun 4 19:04:30 2015 +0200 ms: Add support for maximum CS values Currently the CS values can be increased to CS4 even when the "cs" configuration command has been used with a lower value. The "cs" command just sets the initial coding scheme, so other means are needed to limit the selection. One approach is to use the CS flags passed in SI, but these are currently ignored. To make it possible to limit the CS selection by configuring the PCU, this commit adds the following VTY commands to config-pcu: - cs max <1-4> Limit DL and UL CS to the given value - cs max <1-4> <1-4> Limit DL and UL CS separately (DL first) - no cs max Don't limit Ticket: #1674 Sponsored-by: On-Waves ehf http://cgit.osmocom.org/osmo-pcu/commit/?id=a92f9825845313cee04ee805a6abf1bd30a4ae47 commit a92f9825845313cee04ee805a6abf1bd30a4ae47 Author: Jacob Erlbeck <jerlbeck at sysmocom.de> Date: Thu Jun 4 17:46:33 2015 +0200 ms: Add blocking period for CS upgrade Currently the CS level is immediately increased if the error rate drops below the lower threshold. Since the measurement values are not damped, this behaviour leads to a quick return to higher CS values even under bad radio conditions. Since with GPRS RLC/MAC blocks cannot be resent with another coding scheme, increasing the CS value should be done carefully. This commit adds a blocking period that only allows higher CS values if all error rate measurements were below the LOW threshold for a certain amount of time (currently fixed to 1s).

This commit adds an implemenation that is based on the Ack/Nack ratio per PACKET DOWNLINK ACK/NACK message received from the MS. Basically the CS level is decreased, if the block error rate goes above cs_adj_upper_limit (default 33%), and it is increased, if the rate drops below cs_adj_lower_limit (default 10%). Only blocks that have been encoded with the current CS are taken into account. Note that this approach doesn't measure the MS->BTS conditions and that the measurement values reported by the MS are not taken into account.

Nevertheless the MS object is created after the TLLI gets known, so the value still has to be stored in the TBF initially. This commit add the ms_class value to the GprsMs class and introduces TBF accessor functions which either access that object or, if that is not available, the value stored locally.

Since the enqueued LLC messages are related to a specific MS, they should be stored at that layer. This commit moves the gprs_llc_queue object to GprsMs and changes the TBF's accessor methods accordingly. The LLC copying code is removed from gprs_rlcmac_dl_tbf::reuse_tbf().

This hinders the separation of TBF and MS related data, since LLC queueing belongs to the MS related code while the RLC/MAC encoding/decoding belongs to the TBF layer. This commits takes the LLC queueing related methods and members and puts them into a new class gprs_llc_queue. It puts the queueing object into gprs_rlcmac_tbf and adds accessor functions. The implementation in tbf.cpp and tbf_dl.cpp is adapted accordingly.

The TA storage has at least saved the last 30 TA values. So now in more cases a wrong TA value can be transmitted to an MS. Note that this also could have happened before the removal of the storage, especially if more than 30 MS were in use. This commit changes the default value of ms_idle_sec to 60s which is higher than default value for T3314 (44s, see TS 24.008, 11.2.2), after which the SGSN will have to start paging anyway. In that case, a RACH request will be triggered, that will trigger an update of the TA value in the PCU.
