Holger Hans Peter Freyther 931ad6ac33 nat: Reword the log messages as this is normal operation 
The bsc_mgcp_dlcx method is called from the mgcp policy callback
but also from inside the nat core when the SCCP connection is going
away.

Holger Hans Peter Freyther 462b7d7158 nat: We want the remote to respond to our DLCX request 
We want to send a TRAP with the MGCP statistics from the NAT and
the connected BSC. The BSC endpoint can be either released because
of a DLCX from the MGCP CallAgent or the SCCP Connection release on
the A-link.

This is why we need to queue the statistics when the deleting the
endpoint on the BSC. The processing is continued once the response
arrives. This code assumes that the response of the DLCX will be sent
by the remote side. The current amount of outstanding responses can be
seen on the VTY. This assumption is based on the fact that the BSC has
already responded to the CRCX and maybe to the MDCX.

The MGCP RFC is bended to prefix the transaction identifier with "nat-"
to easily detect the response and hand it to the handler. This will
then parse the response and generate the TRAP. The current version is
v1. We assume that the transaction space is big enough and we will
not re-assign the transaction identifier too early.

Holger Hans Peter Freyther c327187259 nat: Make it possible to send MGCP messages through the IPA multiplex 
Instead of handling MGCP through the UDP socket, read and write messages
through the ipa connection to the MSC.

Holger Hans Peter Freyther 77956aa034 nat: Move all methods sending a response to the callagent to a single place 
For testing it can be nice to handle MGCP messages through the IPA
protocol. Prepare the code to send the messages through other means.

Holger Hans Peter Freyther 6de9d0ba35 nat: Address the FIXME and send the MDCX down to the BSC 2013-04-16 09:17:21 +02:00
Holger Hans Peter Freyther 3dfe8a1705 nat: sizeof char * != sizeof char[], make the code work on 64bit systems 
The test cases were failing on 64bit systems because the sizeof
code operated on the pointer size which is 8 and longer than the
size that was intended to be used for comparing it.

Holger Hans Peter Freyther e2f34d588c nat: Inject a a=fmtp:%d to force the right AMR code 
This assumes that AMR is used and/or the mode-set is ignored for other
codecs by the remote end.

Holger Hans Peter Freyther cb3c2c95bf nat: Make MGCP helper routine static as it is internal to the MGCP code 2012-10-29 19:41:51 +01:00
Holger Hans Peter Freyther 07fc097fc4 nat: Document the high level goal of the MGCP/NAT routines 
Provide some high level documentation that might help to understand
what this code is supposed to be doing.

Harald Welte d36ff76f9d Fix build of bsc-nat and GPRS code after include path change 
The last patch changed the osmocore include paths, this fixes some build
problems caused by it

Pablo Neira Ayuso 136f453dd2 src: use new library libosmogsm and new path to headers in libosmocore 
libosmogsm is a new library that is distributed in the libosmocore.
Now, openbsc depends on it. This patch gets openbsc with this
change.

This patch also rewrites all include path to the new
osmocom/[gsm|core]

Harald Welte a17faf8512 Rename bsc_nat -> osmo-bsc_nat and bsc_mgcp -> osmo-bsc_mgcp 
This now enforces a unique structure: All of our main daemon
programs start with an "osmo-" prefix.
