Holger Hans Peter Freyther 511f9c3e4a si: Partially implement the range encoding for the SI.
I saw the old copy of the "Appendix J" code too late and I have
discovered some quirks and I am more familar with my implementation.
Most noticable 'w' only needs to be as big as the input arfcn but
requires the 'w' to be initialized. The power_of_2 implementation
differs as well (mine matches the output of wirehsark).

The f0 could be chosen in a better way but right now picking
the lower bound is the easiest. It is not clear if to use
modulo if the range is chosen in the middle. This can be improved
in the future. Right now I have no bit fiddling for range128, 256
and 1024 as I was running out of time.

Holger Hans Peter Freyther 18fa70aa3a bsc: Look for CM Service Requests with emergency cause
Look for emergency calls and send them to a MSC that can
handle them properly.

Holger Hans Peter Freyther 210565ed8c bsc: Introduce a local MSC type and forbid it from being selected 2012-09-11 18:01:52 +02:00
Holger Hans Peter Freyther 644b0bf3da bsc: Hand the msc_connection to the UDT handling, pass it to paging
Pass the osmo_msc_data to the paging sub system, change the code
to pass the osmo_msc_data instead of network + bsc_msc_conn.

Holger Hans Peter Freyther 076af1c54b bsc: Move the finding of a MSC into the filter code
For responding to paging on the right link we will need to
figure out if the msg is a paging response.

Holger Hans Peter Freyther 354c87cdfc bsc: Select a MSC in a round-robin fashion
Select a MSC, add it to the back of the list after we have
selected it.

Daniel Willmann 6088f149b5 libctrl, osmo-bsc: Get rid of net prefix
net is now implicit in the root node

Daniel Willmann 65924a5fe8 osmo-bsc: Include rf statistics in the location-state TRAP as well
The first fields are still the location up to the height.
The next field is "operational" if any of the trx are operational,
otherwise "inoperational"
The second to last field contains "locked" if all of the trx are in the
admin state, otherwise "unlocked".
The last field represents the rf policy currently in effect. It is one
of (on|off|grace|unknown).

<tstamp>,<valid>,<lat>,<lon>,<height>,<oper>,<admin>,<policy>

Harald Welte e422798866 RSL: Add basic support for CSD transparent mode
We now have a lchan->csd_mode member that determines if RSL should
activate the channel in CSD transparent services or not.  The previous
code always assumed CSD is non-transparent.

(This requires libosmocore >= eed26116c96f03c6128fac3dead9054714af6cab)

Harald Welte e555c2b545 VTY: dynamically create BTS "type" command syntax 2012-08-17 13:02:12 +02:00
Harald Welte 4ab9d7c012 dynamically generate a proper VTY reference for phys_chan_config
this uses vty_cmd_string_from_valstr() from _very_ recent libosmocore,
so you have to update the library, sorry.

Harald Welte f383aa11a5 BSC: introduce new "sysmobts" BTS model
so far, osmo-bts/sysmobts used to be entered as "sysmobts" type in the
configuration file.  However, there are some differences in the
protocol/behaviour and we should reflect that by a new BTS plugin (with
lots of code reuse from the nanobts driver).

Harald Welte 019f913ca3 gsm_data_shared: add structure for decoded parameters of RLC config
this is primarily needed on the BTS side, but we should also use it on
the BSC side and make the parameters VTY-configurable.

Harald Welte edcba4e307 use new external libosmogb (part of libosmocore.git)
This removes the libgb (GPRS NS/BSSGP) code from the openbsc.git
repository and uses the new version from libosmocore.git instead.
2012-06-17 23:34:34 +08:00
Harald Welte d24566ac6e libgb: separate header files related to spec and implementation
like in libosmogsm, we separate between header files that are just
reflecting information in the respective specs, and header files that
related to our specific implementation.

Harald Welte ce95b27b68 libgb: make sure all BSSGP functions have bssgp_ prefix
We change the minority of functions employing the gprs_bssgp_ prefix to
match with the majority without gprs_ in front.

Harald Welte 11461a6457 libgb/gprs: don't use log_info from libcommon anymore 2012-06-17 12:58:46 +08:00
Harald Welte e6599ee180 libgb: prefix all NS related functions with gprs_ 2012-06-17 12:38:07 +08:00
Harald Welte b1fd9022eb libgb: don't call directly into GMM / LLC layer
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()"

Harald Welte faa70ff2c6 libgb: remove dependency of BSSGP to include sgsn/gmm internal structs 2012-06-17 09:31:16 +08:00
Harald Welte 68d85d5610 libgb: Remove dependency to openbsc/debug.h 2012-06-16 17:53:38 +08:00
Harald Welte fdd8b3b40d libgb: remove dependencies to openbsc/vty.h and openbsc/gsm_data.h
Rather than using openbsc internal data/functions, we now use only
internal and libosmocore-provided ones.
2012-06-16 16:59:50 +08:00
Harald Welte a6a20b4ff6 libgb: Use library SS_L_NS instead lf local SS_NS
which removes some further dependencies of libgb to openbsc internal
code and data.

Harald Welte 8645e101da libgb: move GPRS specific msgb CB definitions to separate header 2012-06-16 16:09:52 +08:00
Harald Welte ea34a4e3a7 split libgb into a separate library for outside use
This also removes the dependency to osmo_sock() inside libcommon and
replaces it with osmo_sock_* from libosmocore

Harald Welte 67161f27d1 Allow VTY-based configuration of T3105
This timer will only be forwarded to BS11 and Ericsson Abis so far,
not to Nokia and ip.access BTS yet.

Holger Hans Peter Freyther a8090d54d6 mgcp: Make it possible to drop RTCP packets coming from the BTS/Net
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.

Holger Hans Peter Freyther 20fea24515 bsc: Prepare to have multiple MSC connections
We now have a list of MSCs but in the code we will
try to access the MSC with the nr 0.

Holger Hans Peter Freyther abd668a68d bsc: Move more things to use osmo_msc_data* directly 2012-03-16 11:56:10 +01:00
Holger Hans Peter Freyther 4cdb050d13 bsc: Move away from ->bsc.msc to use the selected MSC
For multiple MSCs we should only have one place where the MSC
is selected and the rest will extract it from somewhere.

Holger Hans Peter Freyther 8ec4952557 bsc: Create a osmo_bsc_data and embed osmo_msc_data
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.

Harald Welte ae1997248c mgcp: implement a more tolerant parser based on strtok_r()
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.

Holger Hans Peter Freyther 54fa2c7eab abis_rsl: The rach information was not used, introduce a signal
Introduce a SS_CCCH for the paging and the rach load. The paging
code could now start using the signal.

Harald Welte cf149eebb6 Move the bulk of RR processing from MSC into BSC
RR Messages like STATUS, GPRS SUSPEND, HANDOVER COMPLETE/FAIL, ...
should be processed on the BSC side of things, not on the MSC side.

This is among other things required in preparation of intra-BSC
hand-over support in osmo-bsc.
2012-01-23 16:40:24 +01:00
Harald Welte 95e862cab4 Move processing of CLASSMARK CHANGE behind bsc_api
This prevents osmo-bsc from sending RR messages to the MSC and rather
process them inside the BSC and turn them into BSSAP CM UPDATE.
