While doing so, we also restructure/reorganize the vailidity period
parsing in general.
|
|
- Make sure that on runtime the Radio Carrier can be
locked and unlocked. The vty code calls into the
Abis NM to lock/unlock the channel and the state is
stored there.
- Make sure that on start the Radio Carries remains
offline and we are not starting it. On start the
radio carrier is either locked or unlocked. This means
the RSL will not connect until the RF is unlocked. It
will connect then. To see RSL bringup failures one
needs to parse the RSL nack message.
- When the TRX is locked on startup the RSL link will
only be established after it will be unlocked.
|
|
On cold start the RSL link will not be brought up. Wait for the
Software to be Activated before starting the RSL link. This is
working reliable on the BTS I have tested with.
This is a partial revert of 8406ec2437fcc28906b2085e305d79ae73accc2a and
was discussed on the mailinglist.

In file included from sms_test.c:27:

Add it to the configuration files and make use
of it in the the paging.c.
|
|
There are all set to 0 and not used within the code yet but
should be used in the future.

Follow notes:
2.) Allocate a SDCCH for type "LMU"
2a.)Allocate a SDCCH for the three reserved types
2b.)Pick LCHAN type none to "ignore" the request

The implementation is taken from a blogspot and I don't think
it is copyrightable...
|
|
Mention the two new header files, do not list isdnsync twice
|
|
This script is parsing the values, converting the bits into
a number and replacing the text... This should help to go from
spec to code more quickly... next thing would be this for the
structs used...

Allow to configure the number of endpoints at start. Currently
this will not be changed at runtime but one needs to save the
config and restart the system.
|
|
Do not guess the RTCP port as it might be the RTP port
of another connection.
|
|

Forget where the bts and network is located on DLCX and CRCX otherwise
we would have forwarded BTS data to the wrong endpoint and would have
not tried to discover the BTS again.
In the case of early bind we might get data from the BTS before
the CRCX and after DLCX... just ignore it then

This is a simple echo functionality in the MGCP... it
will send the audio back to the network|bts..

The python script is a simple call-agent driving the
client. Currently it is sending a AuditEndpoint message
and is printing the result.
The bsc_mgcp.c is a standalone process that will implement
a MGCP Gateway for the MSC. On call handling the Call-Agent
will ask the Gateway to "CreateConnection" and then this
gateway needs to communicate with OpenBSC.
Currently CreateConnection,ModifiyConnection,DeleteConnection
and Endpoint auditing is implemented.
[mgcp] Send RSIP on start and on first receive of any message
Ignore the first request and send a RSIP. We do that because
we might tunnel UDP through some other things and have no direct
way to connect to the call-agent.
Also the transaction is not checked and we ignore the response
from the call-agent, actually we print the '200 ' or any other
value as unhandled...
[mgcp] Print the MGCP command next to the response code
This allows to see which commands were sent by the server
mgcp: Terminate it with a new line
[mgcp] Make number of endpoints static...
For now this is fixed to the number of endpoints as of the GSM
specification...
[mgcp] The endpoint names seem to be base 16... use strtoul to parse
Use strtoul to parse the base 16 number from the mgw string.
[mgcp] Log the endpoints as hex numbers...
[mgcp] Only send the RSIP on the first incoming message..
Remove call_agent option (also remove the number from the getopt
call).
[mgcp] Start couting at 1 for the mgcp
[mgcp] Slight attempt to improve the grammar of the strings
[mgcp] Share validation routines between DLCX and MDCX
[mgcp] Remove help for dead config options
[mgcp] Specify a different IN addr in the SDP records
In case of NAT traversal be able to listen on a given
interface (like 127.0.0.1) but claim to receive data
at the beginning of the tunnel.
[mgcp] Fix the static copy of the SDP file
WIP verify out factoring broken..
[mgcp] Introduce VTY to the mgcp for config file parsing...
Parse the MGCP config file via the VTY framework.
[mgcp] Handle SDP parameters through VTY..
Currently the payload type, name and rate can be specified
in the config file.
[mgcp] Add an option to bind all rtp ports early
This can be useful for testing and in deployment to make sure
no runtime resource limit can be hit.
[mgcp] Add some API doc comment
[mgcp] Convert the packets of the example server to ascii
This will allow to easily patch the call id... to run the
server in a loop and make it work with the mediagateway
[mgcp] Assign CI_UNUSED... to be more obvious...
[mgcp] Use DEBUG and not DEBUGPC and specially not printf
Improve the logging a bit in the mgcp
[mgcp] Change the fake server to change the call id
This assume the call-agent will just increment the id
as well.... this is true for our implementation
[mgcp] Generate the transaction id dynamically..
This way wireshark will be more happy about it...
[mgcp] Recognize responses from the network..
This is just recognizing the response code and
then is doing nothing with it. Also change the
script to generate response messages...
[mgcp] Improve debug messages for CRCX/MDCX..
Log on which ports the media gateway is listening
and where the other (server) gateway is located

Currently this will send a dummy inactivity test message,
there is currently no parsing or API to receive the messages.
The sequencing and credit entries are empty as sequencing
is currently not used at all.
The test is currently limited to send the message and see
if the application is crashing or not.

include/sccp/sccp_types.h contain Q.713 and GSM definitions
include/sccp/sccp.h is the application interface resembling
the esentials of the UNIX socket interface.
src/sccp.c is the actual implementation of SCCP featuring
connection and UDT1 support.
tests/sccp/sccp.c is testing connection creation and formating
of the SCCP messages used by the A-interface. And
it contains a simple fuzzing test to test the
robustnes of the implementation.

Both GSM 04.08 RR and GSM 08.58 RSL need the multirate config
in the channel modify. Place the config in the lchan, change
the gsm48 methods to not take the argument, change the RSL
implementation to make use of it with the right IE.
The other code should use the t(l)v_put routines as well but
were left untouched for now.

Reset the whole array instead of just the first element.
|
|
- Rename BIND to CRCX
- Rename CONNECT to MDCX
- Add break to properly decode the MDCX RSL packets
|
|
Change the CRCX after the channel has been modified.
|
|
IPA is naming these functions CRCX, MDCX, DLCX to follow
the naming of the MediaGatewayControlProtocol. Change the
code to go from BIND to CRCX (create connection) and from
CONNECT to MDCX (modify connection).
Connect indicates that it is only possible to call it once
while it is possible to call it more than once to modify
the audio parmaters and such. So the IPA terminology is
making a bit more sense here (now that we know it).
|
|
E.g. to analyze the subscr_get/subscr_put behavior one can place
the generate_backtrace into the functions, recompile and then filter
the output with contrib/bt.py to get the function name, file and line.

On channel mode modify and assignment command when using
the a multirate code the multirate configuration must be
present in the packet.
Add a parameter and add a warning when using it in a
broken way.
|
|
Allow to handle the channel requested differently based
on the NECI value for the "paging any" case. This will allow
to open a TCH/H, TCH/F depending on the neci mode.
|
|
Use the correct length when going over the array instead
of using the neci0 values. Remove the fixme from the method
as well as the issue has been addressed by adding a parameter
to the method.
|
|
Not doing this could lead to a double deletion due the paging
request being removed during the callback and afterwards as
well. Change the code to save the callback data, remove the
request, do the callback.
A patch was proposed by Andreas Eversberg and this one is
based on it.

|
Assign the encryption status to the right variable.

Allow to configure the NECI value... and change code
that is relying on the NECI value.
