2013-01-08fix: Use only single CCCH block to determine path lossAndreas Eversberg1-0/+7
The downlink singalling failure counter DSC is decremented by 4 in case of unsuccessfull decoding of CCCH block and incremented by 1 in case of successfull decoding of CCCH block. The initial and maximum value of 90 requires to check the signal only once per 51 multiframe. If DRX would be supported, only a subset of 51 multiframes are received, so the initial / maximum value of 90 must be reduced accordingly.
2012-11-20Tell L1CTL_FBSB_REQ the expected received signal levelHarald Welte1-1/+2
As Dieter points out, this drastically improves the resiliance to high receive levels on the C155. We cannot blindly assume a received signal level of -85 dBm if the BTS is 2m away and we actually receive -40 dBm. This patch extends the L1CTL_FBSB_REQ data structure in layer 1 with the respective field, as well as the l1ctl_tx_fbsb_req() API function called from the various layer23 apps. "mobile" and "bcch_scan" already did a PM request and thus know the expected signal power. "ccch_scan" and "cbch_sniff" apparently don't do, so the -85 dBm constant is now hardcoded into the host-side source code there, and should probably be fixed in a follow-up patch.

2011-11-13host/layer23: Removed local copy of LAPDm, using libosmocore instadAndreas Eversberg1-1/+1

2011-07-17[layer23/mobile] Improvement and fixes of idle mode processAndreas Eversberg1-1/+4
This patch introduces cell re-relection. When camping on a cell, it scanns neighbour cells. If a 'better' cell is found, the cell is selected. If the cell is in a different location area, a location upating is performed under certain conditions. The 'better' cell depends on various informations that are broadcasted on the BCCH of a neihbour cell and of course the RX level. Most operators don't set these informations, so the 'better' cell depend on a better RX level for the same location area, or a much better RX level (6 dBm) at a different location area. There were many issues at the idle mode process that has been fixed. Expecially when moving, the state machines got stuck, so no more cell search was possible, or no further calls / location updating was possible. In order to see the process of cell selection, enter the VTY interface and enable the network monitor: enable monitor network 1 (where '1' is the instance of the MS) In order to see the current state of the processes, enter: show ms

2011-04-26src: use new libosmogsm and include/osmocom/[gsm|core] path to headersPablo Neira Ayuso1-10/+10
This patch changes include paths to get osmocom-bb working with the current libosmocore tree. Among all these renames, you can notice several tweaks that I added on purpose, and that require some explanation, they are: * hexdump() in osmocon.c and osmoload.c has been renamed to avoid clashing with hexdump() defined in libosmocore. * gsmmap now depends on libosmogsm. Actually I had to cleanup Makefile.am because I was experiencing weird linking problems, probably due to a bug in the autotools. With the change included in this patch, I got it compiled and linked here correctly. This patch has been tested with the phone Motorola C123 and the following images files: * firmware/board/compal_e88/hello_world.compalram.bin * firmware/board/compal_e88/layer1.compalram.bin Using the osmocon, bcch_scan and mobile tools.

2010-10-12[layer23] Implementation of signal loss criteria as defined in TS 05.08Andreas.Eversberg1-9/+45
There are two criterions for lossing a signal, idle mode and dedicated mode. A counter counts down when a frame is dropped, and counts up when a valid frame is received on certain channel. The loss criterion is reached, if the counter reaches 0. The values added to / removed from the counter and the limits depend on the process.
2010-10-05[layer23] Increase sync tollerance by increasing freq_err_thresh1Andreas.Eversberg1-1/+1
This is a quick workarround to make synchronizing to a cell more reliable. Without it, just a few cells will sync. When network search is restarted, no more sync happens. By increasing the freq_err_thresh1 to 10000, many cells sync, even after the first network search.

2010-09-26[layer23] Adding application generated measurement reportAndreas.Eversberg1-1/+5
The cell provides SYSTEM INFORMATION 5* and 6. These are used to create a list of neighbor cells to monitor. Because there is no neighbor cell monitoring supported by layer1, the list has no valid results yet. Currently the average RX level of received frames are used to generate a new report every second. The report is transmitted to layer1 and used there whenever a measurement report has to be transmitted. The timing advance and the current transmit power (as requested by network), is included with every report.
2010-09-18[layer23] SIM client completionAndreas.Eversberg1-0/+36
The SIM client is now complete. Because it usefull for multiple applications, i moved it to the layer23/src/common directory. The SIM reader works together with mobile process. Fixes were made. Thanx to all for testing, finding bugs, and making it work as it is supposed to do. The current version uses special L1CTL messages to send and receive APDUs. This will change in the future, when BTSAP interface is completed. Please note that this client will not work until the layer1 SIM reader fixes and extensions are committed.

This commit features handling of ASSIGNMENT COMMAND. Currently only channel descriptions "after time" are processed, which is mostly the case. The ASSIGNMENT COMMAND is essential, because public networks assign an SDCCH4/8 before actually assigning a TCH.
