On a CC message we will need to remeber where the source local
reference of the network belonged so we can properly identify
the connection when receiving UDT messages.
|
|
This way one can create the bsc_nat structure in unit tests..
|
|
Move patching and reassigning of messages to a new file which
will making testing this functionality more easy.
|
|
Create a BSC<->MSC interface and use it for the BSC MSC IP and the
BSC NAT to reduce code duplication on handling reconnects to the MSC
and cleaning up the local state. The code is only partially tested
and will contain bugs. Currently both the BSC and the NAT will just
exit on connection loss and this way have the current behavior.
|
|
Keep track of SCCP connections so we can clear them
when the MSC is going down.
|
|
We are still writing to the BSC directly and don't make real
use of this feature right now but we will need to do it.
|
|
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.
|
|
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.
|
|
In case the put_lchan is making the refcount drop to zero use the
release reason specified in the put_lchan call. This is used by the
BSC MSC IP implementation for the assignment handling where the old
channel is getting closed with a local end release (1).

Keep a static version as the shell script is not dealing well
with branch tags/names containing text.
Resolve merge conflict in the Makefile.am by adding both sides
to the list of sources for the libbsc.a

This new gprs-conf branch is intended to contain everything needed
to configure GPRS in the nanoBTS, but without implementing the SGSN/GGSN
functionality.
The SGSN/GGSN development will happen in a branch based on this branch
called "gprs-sgsn"

The first non working version to dump the content of the sdp
to the terminal..

* The length of the table is not at a fixed position. We will need
to read the offset, seek there, read the data, convert it to the
host endianes.
* Prepare the code to work with offsets of 0...

Keep track of which RTP payload type to use for which direction.
|
|
The are three policies. Accept, Reject and Defer. This will
allow to handle network connections and such from the policy
callback instead of directly acting on it.
|
|
|
|
|
|
In separation of using the MGCP parsing in another context, refactor
the code to operate on a struct mgcp_config, split out the vty code
from the mgcp_protocol.c, and move the callbacks into the mgcp code.
There should be no functional changes.

|
* use pkg-config from openbsc to find header and library
* move sms and timer tests to libosmocore itself
* ensure "make distcheck" works on both packages

This library is intended to collect all generic/common funcitionality
of all Osmocom.org projects, including OpenBSC but also OsmocomBB
The library currently includes the following modules:
bitvec, comp128, gsm_utils, msgb, select, signal, statistics, talloc, timer,
tlv_parse, linuxlist
msgb allocation error debugging had to be temporarily disabled as it depends on
'debug.c' functionality which at the moment remains in OpenBSC
|
|
|
|
The msgb class is using the debug framework and needs to be able
to output data. We would need a way to add custom areas or to have
the struct of areas outside of the default debug.c... but this can
happen at a later point.
|
|
* include <sys/types.h> to have a definition of the u_intX_t types
* include "linuxlist.h" via local includes so it can be found from
the liblaf0rge directory where <openbsc/ does not exit.
|
|
This is needed for the lib where the include directory
is not called openbsc/.

Implement a helper that will allow to easily fill the
tag list with data.
|
|
|
|
* Provide access to the GSM0808 TLV attributes so we can use it in
the nat code.
* Read the PAGING message, if it is paged by LAC we go through each
LAC and then attempt to find the proper BSC connection and then
send the message to that BSC.
|
|
Based on the token the NAT/MUX is capable of figuring out
which LAC this BSC is supposed to satisfy. This will be
needed for messages like paging that can be done by LAC.

* Create struct bsc_nat and move the various lists into this structure
* Create the VTY code
* Call the VTY init and parsing code
* Create functions to create the types..
* Add some stuff into the bsc_connection to be used for the NAT with
proper config files. E.g. to close the connection if the BSC does not
respond to a given command.

Make sending of the ID Request message public. We are going
to use this in the BSC NAT code to ask for querying the BSC.
|

This way the VTY code can use the structures to implement
the show functionality.
