This reverts commit 55a0716da7d06860addfba1812c309eac6d82f1a.
Using a TCH/H, TCH/F for paging purpose any will break the MT-SMS
case because this needs a SDCCH to establish SAPI=3. The On Waves
BSC Master branch has support for early assignment now so this hack
is not needed anymore.
|
|
Specify how we intend to use the assigned channel. This is
needed to make CC with early assignment work properly.
|
|
Change the signature to take the lchan were the message is supposed
to be sent and the lchan which is supposed to be assigned.

The biggest problem is the moving of the RTP code into
the RSL layer. This may break quite some things...
|
|
Move the function over to the _utils side as handover
measurement is compiled into libbsc and we don't want
to end up with linking errors.
|
|
the statistics will give us some idea about the network load and
performance.

This is needed by a yet-to-be-implemented handover algorithm, after
it has allocated a new lchan for the MS. Also missing: handling
the actual HANDOVER COMPLETE / FAIL messages in response.

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
|
|
In the case the MS is requesting a channel with the
paging any channel reason, use a TCH. This allows us
to keep using very early assignment and the SDCCHs are
kept free for location updating requests.

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.
|
|
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).
|
|
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.
|
|
Allow to configure the NECI value... and change code
that is relying on the NECI value.
|
|
Move the handling code to the gsm_04_08_utils.c and add a
note that the method value needs to be checked.
|
|
Be able to send RR CHANNEL MODIFY from the BSC/MSC code
as well. Move the method that knows about the IPAccess RTP
and issues the "bind" to the utils tool
|
|
Add code to generate an assignment command for a given lchan. It
is expected that the lchan is modified already and the mode will
be picked up from their. Currently only the mandantory items
are supported.
|
|
This parameter controls if the response should include the
IMEISV or not. This will be set by the MSC and this is why
this parameter was added.
|
|
Be able to use the cipher mode command message from the MSC code.
|
|
Add one method to extract the MI which will allow to load
the gsm_subscriber depending on the MSC/BSC setup and then
use gsm48_handle_paging_resp to finish the paging response
handling.
|
|
|
|
Prefix generate_mid_from_tmsi with a gsm48_, create a new method
to binary encode the imsi. Add a unit test for parsing and decoding.
The implementation can parse the data it generated and the
last octet seems to be filled with the end mark.
|
|
The parsing of the IMSI is needed for the MSC part as well. Move
it to the gsm_04_08_utils.c so it can be used.
|
|
The existing gsm_04_08.c implementation is mixing BSC and MSC
behavior. Move some simple parsing and generation functions over
to gsm_04_08_utils.c to allow a different MSC to define the policy.
