2014-02-26mobile: Fixed compiler warning at gsm322.cjolly/handoverAndreas Eversberg1-1/+2
This patch resolves the following issue: In function 'memset', inlined from 'bargraph.constprop.14' at gsm322.c:325:8: /usr/include/bits/string3.h:81:30: warning: call to '__warn_memset_zero_len' declared with attribute warning: memset used with constant zero length parameter; this could be due to transposed parameters [enabled by default]

2014-02-26mobile: VTY provides two options to disable neighbor cell measurementsAndreas Eversberg3-15/+54
1. "no neighbor-measurement idle": neighbor cell measurement for cell re-selection 2. "no neighbor-measurement dedicated": neighbor cell measurement for handover

2014-02-26mobile: Keep track of cell channel description during dedicated modeAndreas Eversberg1-23/+44
The initial cell channel decription is received via SI1. During a call this description may change due to handover, assignment, frequency redefinition. Whenever it changes, the last received cell channel description is used to handle messages that do not include this information element. Example of one call with handover inbetween. The assignments do not include a cell channel description: IMMEDIATE ASSIGNMENT: Use cell channel description from SI1. ASSIGNMENT COMMAND: Re-use cell channel description from SI1. HANDOVER COMMAND: Use new cell channel description from HANDOVER COMMAND. ASSIGNMENT COMMAND: Re-use cell channel description from HANDOVER COMMAND.
2014-02-26mobile: Use only sel_si for informations about the current cellAndreas Eversberg4-44/+68
sel_si structure tracks content of SI5* and SI6 messages. The informations will change after handover, so they do not refer to the origin cell. The list of scanned cells is not affected. The sel_si structure will be overwritten with the selected cell after leaving dedicated mode.
2014-02-26[WIP] HO: VTY test option to fake a better neighbor cell to force handoverAndreas Eversberg2-1/+83
The handover is forced by reporting perfect measurement results of a given neighbor cell. All other neighbor cells and the serving cell is reported as poor. The falke report will sustain until the connection is released or a new 'better' cell is specified.
2014-02-26[WIP] HO: Completed handover process at mobile (layer 3).Andreas Eversberg2-175/+429
The implementation supports: - Non-synchronised handover - Synchronized handover - Pre-sychronized handover - Pseudo-synchronized handover
2014-01-29[WIP] HO: Add new parameters to L1CTL_DM_EST_REQAndreas Eversberg3-15/+40
* Flag to enter dedicated mode with TX disabled * Flag to use sync info of neighbor cell * Flag to use sync info of previous serving cell * Index of neighbor cell All these parameters are required to handover to a new channel.

2013-01-10mobile: Fixed CLIR invokation / suppressionAndreas Eversberg1-2/+4
If "clip" is given at vty, CLIR must be suppressed, which results in presentation of caller ID digits, even if suppressed by network. If "clir" is given at vty, CLIR must be invoked, which results in restriction of caller ID digits, even if not suppressed by network. Note: This only work for outgoing caller ID. Incomming caller ID restriction cannot be suppressed.

2013-01-08mobile: Fixed ignoring of MDL-ERROR-INDAndreas Eversberg1-0/+1
Some MDL-ERROR causes must not lead to link failure. The missing "return 0" causes all errors to be ignored which are not listed inside switch/case statement.
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.
2013-01-07mobile: Allow test card to be maked as already attachedAndreas Eversberg3-15/+71
This way it is possible to use test card without making attachment to the network, if the LAI matches. It can be used to do faster testing.
2013-01-07mobile: Improved exit of mobile process, reset phoneAndreas Eversberg3-19/+62
If mobile phone has started, it is reset after shutdown. This ensures that the phone is not transmitting anymore, especially while shutting down in dedicated mode. Using CTRL+c: The first signal causes initiating of shutdown with detach procedure. The second signal causes initiating of shutdown without detach procedure. The third signal will exit process immidiately. (in case it hangs) Using CTRL+z: The first signal causes initiating of shutdown without detach procedure. A subsequent CTRL+c would exit process immidiately.

2013-01-02l23 sysinfo: defer SI4 CBCH mobile allocation until SI1 is receivedAlex Badea1-0/+1
When parsing SI4, there's a check and a log message saying that CBCH MA is ignored until SI1 is received. Then the MA is decoded anyway -- incorrectly -- such that it remains incorrect even after receiving the next SI1. Fix that with an "else".

2012-11-22Rename various "rxlev" variable to "rxlev_dbm" and correct their signessAndreas Eversberg6-40/+40
All levels in range of 0..63 are now uint8_t and use "rxlev" as variable name. All levels in range of -110..-47 are now int8_t and use "rxlev_dbm" as variable name.
2012-11-22fix previous commit: use dbm2rxlev()Harald Welte2-2/+2
As andreas points out, there are structure members that are called 'rxlev' but which don't use the scaling (0..63) of the GSM specs, but which are already a signed type and in dBm. So they need to be converted. TODO: Rename those structure members to rxlev_dbm or something that explicitly states it is _not_ an 'RXLEV' value in terms of GSM.
2012-11-20Tell L1CTL_FBSB_REQ the expected received signal levelHarald Welte6-6/+10
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.

2012-10-30Fix: Change T200 of LAPDm if SAPI 0 and SAPI 3 share bandwidth on SDCCHAndreas Eversberg2-0/+37
We use 1 second on FACCH and 2 seconds on SACCH when SMS is transfered during a call on TCH. There is no impact on bandwidth, because SAPIs use differen channels. In order to correctly transfer SMS during SDCCH, the T200 must be raised from 1 (SAPI 0) to 2 (SAPI 0 and 3), so T200 will not timeout before receiving acknowledge from BTS. This is because both SAPIs share the same ressource on SDCCH. After release of SAPI 3, T200 is lowered back to 1.
2012-10-30Fixed decoding of hexadecimal LAI componentsAndreas Eversberg4-23/+40
libosmocore has changed its LAI decoding from hex to decimal. This caused wrong decoding of MCC and MNC. In order to provide required hex transcoding, special hex encoding and decoding function are added to mobile/sysinfo.c.
