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'
Remove the separation of half-rate and full-rate AMR. The used rate
can be found inside the AMR payload. The signalling of what kind of
traffic channel is used can be done with the GSM 08.08 Chosen
Channel IE in the Assignment Complete message.
This way I can use a fixed payload type in the MGCP GateWay but
have a mixed TCH/F and TCH/H config. E.g. use TCH/F FR3 for some
subscribers when connected to MSC A but use AMR5.9 on a TCH/F for
MSC B when all TCH/Hs are gone.
Move the regexp parsing code from the NAT to libcommon as it will
be used by the NAT and BSC code. This also adds the #include <regex.h>
include to gsm_data. This header should be split up.
This is a big patch that ports openBSC over libosmo-abis.
Sorry, the changes that are included here are all dependent
of libosmo-abis, splitting them into smaller pieces would
leave the repository in some intermediate state, which is
not desired.
The main changes are:
- The directory libabis/ has been removed as it now lives in
libosmo-abis.
- new configuration file format for nanoBTS and HSL femto, we
need to define the virtual e1_line and attach it to the OML
link.
- all the existing BTS drivers (nanoBTS, hsl femto, Nokia site,
BS11 and rbs2000) now use the new libosmo-abis framework.
- use r232 input driver available in libosmo-abis for bs11_config.
- use ipa_msg_recv instead of old ipaccess_read_msg function.
- delete definition of gsm_e1_subslot and input_signal_data.
These structures now lives in libosmo-abis.
Most of this patch are deletions of libabis/ which has been
moved to libosmo-abis.
This patch also modifies openBSC to use all the new definitions
available in libosmocore and libosmo-abis. In order to do that,
we have replaced the following:
- DINP, DMI, DMIB and DMUX by their respective DL* correspondences.
- SS_GLOBAL by SS_L_GLOBAL
- SS_INPUT by SS_L_INPUT
- S_GLOBAL_SHUTDOWN by S_L_GLOBAL_SHUTDOWN
- SS_INPUT by SS_L_INPUT
- S_INP_* by S_L_INP_* sub-signals
- E1INP_NODE by L_E1INP_NODE vty node
This patch has been tested with:
- one nanoBTS
- the HSL femto with the examples available under libosmo-abis
- BS11 with both dahdi and misdn drivers.
This patch modifies openBSC code to use msg->dst which stores the
pointer to the signalling link structure instead of the pointer to
the transceiver structure.
This patch prepares the introduction of libosmo-abis.
The timer callback will simply reset the lchan state to NONE in order
to prevent channels getting stuck in 'activation requested' or
'deactivation requested' states.
Scenario: BTS are configured and working, then the BSC stops working
for some reason (crash or administrative stop).
If the BSC comes back to life, LAPD among other things does not know
about the previous existing TEIs. Instead of ignoring these frames,
we notify the driver that we are seeing frames with unknown TEIs, so
it can try to recover, e.g. by resending the SABM message.
The MS Radio Access Capability IE can be _very_ long in some recent
high-end mobile phones, way beyond the old 14-byte limit. We increase
our array to 52 bytes, and make sure not to overflow that buffer.
