now it correctly parses BSSGP and displays some more HSL specific IEs

|
This parameter indicates how many of the PCH+AGCH blocks are reserved
for the AGCH and thus not used for the PCH. If we set it to 0,
we basically tell the BTS there is no AGCH - and thus it would be
impossible to send any IMMEDIATE ASSIGNMENTs.
Luckily the BS-11 and the nanoBTS don't seem to care.

SACCH INFO MODIFY is intended to modify the SACCH content for a single
logical channel (as opposed to the default SACCH FILLING)

So far, OpenBSC simply assumed that all BTS's configured in openbsc.cfg are
neighbors of each other. While this is true for small site installations,
it is definitely not true in most real world cases. We now have the
following new commands at the 'configure bts' level:
'neighbor-list mode (auto|manual)' for selecting the mode
'neighbor-list (add|del) arfcn <0-1024>'
for adding/deleting ARFCN in manual mode

Add a short README mentioning the svn version they apply
to, how to rebase them in the future, and what they do.
The renaming is done to add a hint on in which order to
apply them. The abis_oml patch has been updated to some
value_string changes in epan, all patches now add the new
files to the CMakeLists.txt of epan as well.
|
|
These patches were applied to upstream wireshark as of
svn revision r35475.

It got broken in the refactoring of 20474ad02983861cb6a9542916eaeb78a6615604.

Move the SMS from text code from the VTY interface into the
gsm_04_11.c code next to the sms_alloc and sms_free.
|
|
Instead of using more numbers from the proto range we will
use the 0xee and then have a mini header with our new proto
id in there. For a start rename the use types to _OLD.

Switch to a \r\n at the end of the query. Both \n and \r\n
are valid according to the spec but this makes us match
responses of other equipment.

The transaction layer was stopping paging requests that might or
might not have been owned by the transaction. This makes the subscr
code get stuck delivering requests. This code is mostly a band aid
and just makes sure that we will kick the queue if it is needed.
|
|
Remember if this channel got opened due a paging response and in
that case when we close it down we will call subscr_put_channel
that will try to page the subscriber again. This highlights the
lack of a good subscriber management in the MSC code.

If one paging request is timing out the others will timeout soon
as well. With the current code the next timeout would expire the
next request in the queue. We will now stop all paging requests
and then issue a next paging request. So for both paging success
and failure we will now stop all the other requests.
This is mostly a workaround, one should count on how many
BTSes we are paging and wait for all failures before we remove
the item from the queue.
|
|
Kick the queue in case the paging was timing out. No one is going
to call subscr_put_channel for us so we will do it on the subscriber.
There is also another problem with multiple BTS in the LAC and paging
timeout. We will need to remember how many BTSes we have paged.
|
|
If we have a RF failure between the paging response and the auth
success we will not inform the subscriber layer of the failed paging
and instead just 'drop' the SMS. In case we have not completed the
auth and close the channel we will now send an auth failure.

The conn might be released during the loop and then conn->bts
is a null pointer and we end up crashing. Store the gsm_network
in a local variable and access this one.
|
|
Improve the debugging possibilities and print the failed attempts
and the sms that was attempted to be delivered. this should help
with debugging the code.
|

The active channel might or might not be gone when the transaction
has been released. Instead of passing an invalid subscriber conn
we will pass the subscr that is ref-counted and guranteed to be
valid at this point. subscr_put_channel could search the connections
for an active connection if that is ever needed.
|
|
In contrast to the previous believe we may not have a conn here
as we are still paging for the sub. Instead of printing the BTS
print the lac where we think the subscriber is located.
|
|
Follow trans->conn->lchan to the BTS instead of using the BTS that
is guranteed to be NULL in the codepath we have entered here. The
trans->conn should still be there, and the lchan should be valid as
well as we have reordered the clear statements.
|
|
|
|
When the new_lchan for handover is failing we should stop the
handover operation. This is fixing a crash that we get a timeout
on the lchan and have no conn set to it. Introduce a flag to
the bsc_clear_handover to not free the lchan. In case the ho_lchan
is failing we do not want to call lchan_release as it would
reset the state.

The trau_mux likes to call cc_tx_to_mncc for each received
frame from the E1 link. Using a signal for each audio frame
is messy as well. The best thing I could think of is to put
this into the BSC to deref the pointer. The other option would
be to include the gsm_data.h in the mncc.h header and have
the method as inline.
|
|
Include stdint.h to have the C99 data types.
|
|
Instead of creating the sockets in the RSL code we will do this
in the CRCX_ACK, MDCX_ACK, DLCX_IND signal handler of gsm_04_08.
Introduce a handover signal so we can repatch the RTP sockets in
the gsm_04_08 as well.
|
|
|
|
This should make sure conn->lchan is valid throughout the release
cause, especially make trau_mux_unmap() happy that conn->lchan
still exists.
