This removes the libgb (GPRS NS/BSSGP) code from the openbsc.git
repository and uses the new version from libosmocore.git instead.
|
|
We change the minority of functions employing the gprs_bssgp_ prefix to
match with the majority without gprs_ in front.
|
|
|
|
|
|
Instead of direct function calls to individual functions, we now
generate primitives (osmo_prim) and send them to one
application-provided function "bssgp_prim_cb()"
|
|
|
|
|
|
Rather than using openbsc internal data/functions, we now use only
internal and libosmocore-provided ones.
|
|
which removes some further dependencies of libgb to openbsc internal
code and data.
|
|
|
|
This also removes the dependency to osmo_sock() inside libcommon and
replaces it with osmo_sock_* from libosmocore
|
|
This timer will only be forwarded to BS11 and Ericsson Abis so far,
not to Nokia and ip.access BTS yet.

Thanks to Andreas Eversberg for spotting this one.

Add argument handling for the nitb application and create the RF
ctrl interface for being able to control the TRX using an external
socket.
|
|
The nitb will provide the RF interface as well.
|
|
The ip.access nanoBTS appears to send quite broken NTP timestamps in
the RTCP messages might confuse equipment that uses the sender report
of the BTS. Make it easy to experiment by adding an option to drop RTCP.

Thanks to Robert Ingr for pointing this out

Call the channel by the right name.
|
|
In case the connection should not be created/accepted release
the channel by sending a RR Release and de-activating the
SACCH. Phones should deal better with that behavior.
|
|
In case the call handling starts on a TCH/H switch to a TCH/F
if fullrate is requested. Add a method that is used to determine
if the mode and current channel are compatible with each other.

Not all architectures have the tm.tm_gmtoff member. This fixes cygwin
builds.

We now have a list of MSCs but in the code we will
try to access the MSC with the nr 0.
|
|
This is needed for simple UDT messages where we do not have
a SCCP connection.
|
|
|
|
|
|
For multiple MSCs we should only have one place where the MSC
is selected and the rest will extract it from somewhere.
|
|
|
|
We want to have multiple MSCs but we also have some data
that is only present on a per BSC basis. Right now the
MSC data is not allocated with talloc, so we have some
change in the talloc contexts.

Instead of building complex manual byte-wise parsers, we simply use two
strtok_r loops: one iterating over all the lines, the next one
iterating over the invididual space-separated elements in the first line.
The benefit is that we now accept \r, \n or \r\n, or any multiple of
them as line ending. This works around incompliant MGCP implementations
like that of Zynetix MSC.
Addition: mgcp_analyze_header returns 0 when all out parameters have
been set.

In addition to SI 2 and SI 5, the SI 2ter and 2bis is generated, if
neighbour cells in other bands exist. Also it is indicated in the rest
octets of SI3, that SI 2ter is used. If no neighbour cell in a different
band exists, the SI 2ter and SI 5ter is omitted.
A special case is P-GSM range (channels 1-124). To be compatible with
older phones, SI 2bis and SI 5bis is used. If the BCCH lays inside the
P-GSM band, only neighbour cells of the P-GSM range are included in
SI 2 and SI 5. If neighbour cells exist in the same band (900), but lay
outside the P-GSM range, the SI 2bis and SI 5bis is used to extend the
list of neighbour cells. The extension is also indicated in SI 2 and
SI 5. If the BCCH lays inside the P-GSM range, but no neighbour cell
exists in the same band outside the P-GSM range, the SI 2bis ans SI 5bis
are omitted.

strstr() was used with wrong argument order, causing it to always match,
and causing an invalid response to a variety of different SS and USSD
requests.
This has apparently caused havoc among a number of HTC phones which
issue SS requests without user interaction upon boot, and then trip over
our inappropriate response.

This must have been obsoleted by the move to libosmo-abis.

Introduce a SS_CCCH for the paging and the rach load. The paging
