2018-02-05Add stat items for the BTS's channel load average and T3122.Stefan Sperling4-2/+28
In addition to logging the current values of a BTS's channel load average and T3122 override, maintain stat items for these values. This allows for plotting these values over time, for instance. These values show up in the VTY under 'show stats' like this: base transceiver station: Channel load average.: 25 % T3122 IMMEDIATE ASSIGNMENT REJECT wait indicator.: 32 s Change-Id: Icace0176e8b1d23d7c7b4816f7c67c65312844fa Suggested-by: laforge

2018-02-05Make "waiting indicator" of IMMEDIATE ASSIGN REJECT dynamic.Stefan Sperling11-30/+143
The IMMEDIATE ASSIGN REJECT message contains a wait indicator which tells an MS requesting a channel to wait for a specified amount of time before trying to request a channel again, i.e. the wait indicator controls the T3122 timeout value in the MS. Previously, the wait indicator was fixed to 10 seconds. This is not sufficient if there are a lot of MS requesting channels because the MS will retry too soon. Instead of using a fixed value, maintain a dynamic wait indicator value based on average channel load. The load (used vs. available channels on a BTS) is sampled once per second, and once 8 samples have been collected we update a BTS-specific T3122 wait indicator based on the measured load. While the wait indicator could go up to 255 seconds, this initial implementation keeps it in the range from 10 to 128 seconds. Further experimentation and testing will show whether higher wait indicator values are desirable, if the sampling rate needs to change, or if the function mapping the load measurement to a wait indicator value should change (currently we map the load average linearly into the range [10, 128] inclusive).

2018-01-28remove obsolete gsm_subscriber_connection.bts memberHarald Welte4-11/+5
This member was merely a cache for conn->lchan->ts->trx->bts, so let's avoid having to keep copies of the same data (which needs to be kept up to date). Change-Id: Id3bff8b18425ef5d45eb460ac9eb620023013ba0
2018-01-28bssmap_handle_assignm_req(): Decode channel type as first stepHarald Welte1-17/+16
The decision on how to further process the request depends significantly on the contents of the only mandatory IE of the ASSIGNMENT REQ. Let's decode it first. Change-Id: I030b5ad6f4fc33da9155c8a6061fd982312b20fb
2018-01-28cosmetic: Remove data/len variables in bssmap_handle_assignm_req()Harald Welte1-11/+6
There's nothing wrong with passing the TLVP_VAL/TLVP_LEN directly into the gsm0808 decoder functions, let's avoid variables that get assigned and used only once - particularly with such generic names. Change-Id: I8557b4a9ff4de28b76c7d618631a4700176a8669
2018-01-26Improve an error message in page_lai_and_lac()Stefan Sperling2-2/+2
This error message is now contained in a loop, and the current iteration does not know whether paging will fail entirely or if later iterations will succeed. Update the error message accordingly. This also makes the error message consistent with the one in page_cgi(). Change-Id: I8ec229702343343dedcbb242b6d0ed170c858511

2018-01-22HO: Add a penalty timer list to the subscriber connection entityAndreas Eversberg2-0/+20
This penalty timer is used to temporarily block cells where handover or assignment failed or where handover is not allowed. This is usefull to prevent repeated handover attempts to broken cells or cells that have limited allowed distance. Change-Id: I95cb7e3211b2470b773965e7aa94d8eb6c8c1a3a
