The transcoder RESET is using the same extensions to reset all
endpoints on a remote site. This makes sure that all allocations
can be made in a properly configured network.
|
|
The code assumes a static mapping from endpoint to RTP port,
be able to configure the start of such a mapping.
|
|
Bind a new port for the transcoder, forward data from the BTS
to the transcoder, and from the transcoder to the network. Leave
BTS-IN where it is, BTS-OUT can now be after the transcoding took
place. We send the data from the BTS RTP port.
This whole route will be guarded by the transcoder_ip and if it is
NULL (current default) it will not go through the transcoder.

Move the bfd from a static var into the mgcp_config.
|
|
The timeslot one is blocked and should not be used, replace the
code with a warning and watch out for it. Tis is most likely due
the uncovered in the previous commit due the wrong TLV definition.

Send a signal, this way another module can close all connections
to the MSC and all local channels.
|
|
|
|
Add the code that is forwarding data, from and to the MSC, also
handling ping/pong timers and authentication. Hook it into the
osmo_bsc. The code is only compile tested and ported from the
on-waves/bsc-master branch.
|
|
|
|
The grace code will decide if a given connection is allowed to
be made or if it is going to be rejected. For active connections
it is going to send a USSD message.
|
|
Keep a back pointer to the rf struct inside the connection,
resolve the network through the back pointer. Also assume
that the RF is on. In case we start with RF locked, the policy
is on but we will not see any MS talking to us.
|
|
|
|
This group contains everything that is related to the MSC connections.
|
|
|
|
Return early in case the IMSI was already checked, if not we need
to look at the connection and check if the message could contain a
imsi we want/need to filter.
|
|
Return -1 if the IMSI should be filtered, 0 if the IMSI could not
be checked and 1 if the IMSI was checked and allowed to pass. In
the future this will be used to inspect every message coming by.

Only page if we have a load that is acceptable for paging. This
option is off by default, and can be enabled per bts. The idea
is that when we have no resources right now we will not page as
it will only create more RACHs and increase the load.
By default we are keeping the old behavior to always page and
only by changing a setting one is using the new behavior.
|
|
It might be that we run down to zero available slots but the BTS
might not send us a load indication. This can happen if we think
we send paging requests and the BTS disagrees and considers them
as errors and does not count the paging message.
When we drop to zero we will start a credit timer to give us extra
credit after six seconds, if we get a CCCH load indication before
we will stop the timer.
|
|
It is possible that the MSC is not sending the channel type it
needs for the operations it wants to do. Add a configuration option
to assign a TCH in case of paging any requests. It can be a good
idea to leave SDCCHs free for location updating requests and use
the TCH for SMS-MT and CC-MT.
|
|
Store the mapping from request to channel type in the GSM Network
struct as there is some policy involved with handling the request.
E.g. in a half rate network we don't want emergy calls to be getting
a TCH/F, or we want to have a different policy for early/late assignment
of phone calls. Update the table when creating the network and when
the neci is changed.
|
|
Allow the MS to use uplink discontinous transmission by
setting the right bit in the SystemInformation and set
DTXd/DTXu on the RSL channel commands.
This is configurable via dtx-used (0|1) on the network
level and still considered as experimental.
|
|
When the cell becomes visible we will be bombed with location
updating requests and to reduce the load on the network we should
assign as many channels for it as possible. During load peek it
is even more important than to have a spare voice channel and in
general the LU procedure is pretty fast.
|
|
|
|
Add code to replace the Endpoint number for the mgcp.
|
|
Do attempt to not reassign an endpoint immediately but go
to the next free one.
|
|
Assume that if the MSC has assigned a timeslot/multiplex it will
also be used for the MGCP. So we just assume that it was allocated
on the BSC as well... in the worse case we will send a DLCX downstream
but it should be fine.
|
|
We are going to have more than one trunk, so all code hardcoding the
multiplex to zero must go. Avoid this kind of problem by saving the
MGCP endpoint number and comparing that.
|
|
|
|
We really have 32 channels per multiplex... so use the right
number... or at least it seems we do have 32.
|
|
Right now only bsc_hack and osmo_bsc need to have a custom
config handling as they use the subscr/oml nodes.
|
|
Do not use the CI_UNUSED to decide if an endpoint is allocated
but introduce a new flag. This way only the CRCX and free_endp
play with the allocated field.
|
|
|
|
This will allow to have additional debug information and to
use the state inside the forwarding code.
|
|
|
|
For debugging it is useful to forward (tee) UDP packets to another
system and use gstreamer to inspect the rtp stream. This is untested
code and might contain bugs.... and of course only tap your own calls.
|
|
|
|
Allow to switch to a dynamic port allocator and not reuse
the ports for a long time... This should help with a crazy
network sending two streams at the same time.
|
|
|
|
|
|
Use the right source port when sending the message.
|
|
|
|
Stop using the memset in the mgcp_rtp_end_reset as we
will reset the list pointers and then have a mess..
|
|
|
|
|
|
Simplify the code by onlt allowing one way to allocate
a socket.
