Send the current position when the MSC connection is established.
|
|
Send the signal whenever a MSC appears to be authenticated.
|
|
For short IP failures we want the RF to stay up and wait for
the re-connect but in case the A-link is gone too long it is
good to switch off the RF and wait for commands to enable it
again.
|
|
Use the delayed scheduling feature of the osmo_bsc_rf class to
avoid crashing the site controller of the nanoBTS.
|
|
It is possible that MNCC sends a MNCC_LCHAN_MODIFY and
wants a channel mode that is not possible on the current
lchan, in that case a new channel is assigned. We now crash
as the osmo-nitb is not having an assignment complete handler,
add a NULL check.
|
|
When we got a clear request we did not clear the internal
association between the gsm_subscriber_connection and the SCCP
part. When we got a DTAP message before the CLEAR COMMAND we
will end up in a crash as the ->bts pointer of the connection
has been cleared.

Provide VTY options to allow/forbid the usage of a
specific multirate option.
|
|
Handle the mr_config request and set the AMR multirate config for
the given MSC. Initialize the mr_config with the AMR5.9 default we
have been using until now.
|
|
Move it to one place so it is more easy to make changes to
that.
|
|
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.
|
|
The MGCP config must be correct and use 99 for RTP AMR.
|
|
When the CRCX 200 is lost on the way to the CallAgent we will
get another CRCX (retransmission) which was answered with a 400.
Change the code to extract the CallID, Mode and the optional
LocalOptions first. Then check if the endp is allocated with the
same call identifier, in that case return the current session
information.
|
|
The SDP file for FreeSWITCH should contain o= (Origin) and the
t= (Timing) for the session. The data of the Origin should be
globally unique but this is not the case yet. We will need to
store the (NTP) time of the creation of the endpoint.

When we are asked to route calls on a local link and
the link is not available we would crash when trying
to send a packet over a deadline. When we have decided
to move a connection it is guranteed that the current
SCCP connection will vanish, we either migrate to another
MSC or the RSL/subscriber connection will be closed.
|
|
|
|
When a MSC connection drops, only kill the connections that
belong to the given MSC and not all other connections.
|
|
|
|
|

|
Inspect the CC Setup messages and if the dialed number is matching
the regexp of the local MSC the connection will be rerouted. The
original MSC will get a GSM0808 CLEAR REQUEST, a new connection with
a CC Setup message will be opened.
|
|
Look for emergency calls and send them to a MSC that can
handle them properly.
|
|
|
|
Inspect the message and see if it is a paging response,
then try to find the MSC that has paged this subscriber
and select this as the target MSC, also move the MSC to
the back of the list for 'load balancing'.
|
|
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.
|
|
For responding to paging on the right link we will need to
figure out if the msg is a paging response.
|
|
Select a MSC, add it to the back of the list after we have
selected it.
|
|
|
|
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.
|
|
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.
|
|
The commands net.<netid>.bsc.<bscid>.* are now forwarded to the
appropriate osmo-bsc. <netid> for now is just 0. <bscid> is not the LAC
anymore (since that could be ambiguous), but instead the number as
configured in bsc-nat.cfg
|
|
net is now implicit in the root node

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>
