Andreas.Eversberg 3e1574bc6a [layer23] Added control features to VTY 
tx-power: fixed or automatic transmit power selection
(not currently supported by layer 1)

simulated-delay: Make BTS believe that we are closer or at greater distance
than we actually are. This is required to use cells that only allows a limited
range to the mobile. Also it prevents from being tracked by location services.

stick: Make mobile stick to a given ARFCN only. For testing purpose the
cell selection process can be limited to only one frequency. This speeds
up cell selection process.

Andreas.Eversberg 5bbc44e913 [layer23] Fixed ID.REQ for IMEI while no SIM is present. 2010-07-13 14:27:15 +00:00
Andreas.Eversberg 6ba18aeb03 [layer23] Rework of channel request process and control of TA and TX-power 
The radio ressource layer uses RSL messages to perform RACH requests now.

TX power and timing advance is controlled before RACH request, after IMM.ASS,
and during dedicated mode. (Note that TX power control is not yet supported
by layer 1.)

Andreas.Eversberg 65df98d930 [layer23] Correcting an attribute name in sysinfo.h. 2010-07-13 14:14:54 +00:00
Andreas.Eversberg f7c137660a [layer23] Updating l1ctl.c to current L1<->L2 API. 2010-07-13 14:12:54 +00:00
Andreas.Eversberg c6ff4723ce [layer 1] L1CTL_PARAM_REQ is introduced to change TX power and TA. 
Currently only TA (timing advance) is supported. It ranges from -128 to 128.
 2010-07-13 14:07:37 +00:00
Andreas.Eversberg 9a422ceb25 [layer 1] Reset option for scheduled frames. 
This is usefull to drop a scheduled RACH request after an IMM.ASS is
received.
 2010-07-13 14:03:13 +00:00
Andreas.Eversberg 0719e9ac7d [layer1] Added mf_off to shedule next RACH request. 
The mf_off value defines the offset of multiframes.

Harald Welte f633ea5f43 Merge commit '33f0fc3c9565308044c934c9e0c1bb81c1a26311' 2010-07-13 13:51:42 +02:00
Andreas Eversberg 33f0fc3c95 [VTY] add support for numeric ranges with negative numbers 
This enables us to do something like <-128-127> as a numeric range.
 2010-07-13 13:50:39 +02:00
Harald Welte 6eb7d6c887 [RSL] split rsl_rll_push_l3() L3 LV pushign and rsl_rll_push_hdr() 
This allows us to generate RSLms messages that have some non-standard
IEs between the RSL/RLL common header and the L3 INFO IE.

Andreas Eversberg cd2a74bd43 Added single octet TV (type + value) to libosmocore. 
In case of a single octet, the upper nibble is the type, the lower nibble
carries the value.

Andreas.Eversberg 7b84cf805b [lapdm] Added flow control between L1 and L2, so DM mode does not crash. 
In dedicated mode a frame is sent to layer 1. Subsequent frames are queued
inside lapdm.c until a confirm from layer 1 is received. Since not all
pending frames are sent rapidly at once, the layer 1 does not crash anymore.

Also included in this commit: handling of reset confirm (maybe required
in the future after dedicated mode)

Andreas.Eversberg 4e03d6f822 [layer23] Fixed DM est./release for current supported channel types.

But some tests showed me that it doesn't work. Please help debugging.

Added DM release function to l1ctl.c and gsm48_rr.c.

Harald Welte 44239b448b [layer23] make sure we recognize our own IMM ASS 
When trying to re-create the header file I made the 'valid' member
of the channel request history a single-bit field, but we actually
assign values different than 0 and 1 to it.  This has caused layer23
to consider the IMM ASS to our own channel requests as non-matching.

Harald Welte 028dcd9e25 [layer1] An actual AGC implementation 
We introduce trf6151_compute_gain() to compute the gain setting that
leads to the ideal analog baseband power input level.

This function is called from rffe_set_gain() for both the compal and
the gta0x rf frontend, as there are no other amplifiers inside those
phone designs.

The new AGC function is not used yet from the regular layer1 code.

Harald Welte 52ef5a78ee [layer1] Power Measurement updates 
Instead of using the 'normal burst' receive window, use the proper
RXWIN_PW for power measurements. However, in this case, one PW window
corresponds to one PM measurement and in order to do two measurements,
multiple PW windows need to be set-up in the TPU.  Since we don't support
that yet, we simply switch to doing only one power measurement for now.
