Decoding and encoding of FR and EFR TRAU frames are put into seperate
functions. CRC check is done to detect bad EFR TRAU frames.
The test case includes FR and EFR transcoding.
EFR support was tested with Nokia InSite BTS and Siemens BS11.
Increase the version number and send the sizeof of the gsm_mncc
and the gsm_data_frame structure. Include the offsets of some
members as well to maybe identify ABI problems.
The reason we go through this is that we want to benefit from
the native ABI and don't want to force packed structs.
Send a hello packet down to the client with the version number
of the MNCC interface. The hello structure might be extended to
include the endianes, size of each structure, etc.
In order to have the MNCC application reliably decide on the codec type,
it needs to know if we are running on a TCH/F or TCH/H. Thus, we pass
lchan_mode as a new parameter to the 'struct gsm_mncc'
libosmogsm is a new library that is distributed in the libosmocore.
Now, openbsc depends on it. This patch gets openbsc with this
change.
This patch also rewrites all include path to the new
osmocom/[gsm|core]

This adds mncc_sock_from_cc() as a handler function for CC messages
to be passed to the MNCC interface. If there is no MNCC socket
registered, we immediately release any CC related messages.
Together with flushing all established CC transaction at MNCC socket
close time, this ensures that all resources are released and no
new resources can be established until the MNCC applicaiton has
re-attached.
The reason for this is quite simple: We want to make sure anyone
running a customized version of OpenBSC to operate a network will
have to release all custom modifiations to the source code.
This library is intended to collect all generic/common funcitionality
of all Osmocom.org projects, including OpenBSC but also OsmocomBB
The library currently includes the following modules:
bitvec, comp128, gsm_utils, msgb, select, signal, statistics, talloc, timer,
tlv_parse, linuxlist
msgb allocation error debugging had to be temporarily disabled as it depends on
'debug.c' functionality which at the moment remains in OpenBSC
Instead of passing TRAU frames down the MNCC API to the call control
application like MNCC, we now decode the TRAU frame into the actual codec
frame. We do the same with the RTP packets in case of ip.access and
thus have a unified format of passing codec data from the BTS to
an application, independent of the BTS type.
This is only implemented for V1 full-rate at the moment, and needs
to be fixed.
This is Harald's reworked MNCC base, slowly heading towards integration
into master. The key changes are:
* provide much more structure to the data in gsm_mncc
* encode_* and decode_* functions now take a structure rather than tons
of individual arguments (whose order nobody can remember)
* make sure we don't have copies of the same code everywhere by introducing
mncc_set_cause() and mncc_release_ind()
* save horizontal screen space if possible
* make sure we break lines > 80 characters
