This is causing a regression with AMR audio. The nanoBTS
is sending a MDCX NACK with Cause 0x52. Reverting this
commit makes it work again.
This reverts commit b54dda4cefe89665d98074cf3767858fa6ecdb6e.

This is an ip.access specific 08.58 oddity. It reports 0xffff
available paging buffers if the paging load is below the 12.21
CCCH LOAD INDICATION THRESHOLD.
We use 50, since that is what it reports if the threshold == 0.
|
|
When the cell becomes visible we will be bombed with location
updating requests and to reduce the load on the network we should
assign as many channels for it as possible. During load peek it
is even more important than to have a spare voice channel and in
general the LU procedure is pretty fast.

Add two new counters to count the RF Failures and the RLL Release
failure and make them available via the vty interface.

For GSM V1 FR, the payload type is fixed to 3 in the RFC.
But for the other codecs, the payload type is dynamically assigned
between 96 and 127. Here, we use a static mapping internal to OpenBSC.
This patch is needed to make a rather old 139 unit (with sw version
120a002_v149b42d0) work with something else than FR codec. I also tested
this patch on a newer 139 (with sw version 120a352_v267b22d0) to make
sure it didn't add a regression. More testing with newer EDGE units
should be done by whoever has some of theses.

Currently our GSM04.11 code is closing the link for SAPI=3
and this would mean that the whole channel would be scheduled
for close... where we only want to close everything when freeing
the lchan or handling an error.
|
|
Setting the state through a dedicated method allows us to
track the state transitions and check if they are done in
a proper way.
|
|
1.) free every SAPI from 1-7 and wait for the confirmation
and then continue until all of them are freed. If the
SAPI is not torn down we will receive a timeout and then
we force the RF Channel Release...
2.) once SAPI is down we send the RR Release, SACCH Deact
3.) the abis_rsl will see that all SAPIs are down and then
will release channel...

When we issue a RF Channel Release in case of a failure we receive
RLL release indications after the channel was tearn down and we
issue another RF Channel Release as a result. The channel allocator
might have already allocated this channel and we release the channel
again with another MS on it.
Make rsl_rf_chan_release take an error argument and make it set
a new state in case of an error and change the RF Channel Release
ack to not set the state back to none in case of an error but wait
for a timeout that is a bit higher than T3111.
I tested this with removing the battery during a phonecall and
waiting for the channel failure. With this test we only send the
release once.
|
|
|
|
We assume that the lchan_free will initiate the release and
that when we handle the RLL release indication or the release
request as part of the shutdown sequence.
|
|
The current channel release has a couple of issues we will
need to fix in a set of upcoming commits.
The issues include:
1.) sending release twice
2.) reassigning the channel inbetween the relase..
|
|
The theory is that the BTS is almost dead and sends out
a incomplete message and we crash with that. I have not
been able to completely verify that.

* Move to the new log code and update binaries
* Catch up with lchan changes from master

We use the (currently unusued) flags member of the bts_trx_ts structure
to track if a dynamic TCH/PDCH is currently on PDCH mode or not.

The logging/debugging code is generic enough to move it into libosmocore
while keeping OpenBSC specific definitions in openbsc itself.
This commit uses the logging support present in libosmocore-0.1.2,
you will have to update your library to this version.
|
|
|
|
Prepare to split the BSC and the MSC part by putting the
MSC data for a connection into a "gsm_subscriber_connection"
struct and renaming the macros.
|
|
the 0.1.1 API is cleaned up and removes all exported global static
arrays (like rlm_cause_strs). There are now proper accessor functions.
|
|
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).

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

If the lchan has AMR as speech codec we also need to send the
multirate config IE in the channel activation. This is already
done for the RSL Channel Modify message.

This is partially reverting 0603c9d9e58b5d29105361a89ab8cb295da29366,
it is true that the ip.access Wireshark dissectors differentiate
TCH/H from TCH/F but in my test I'm unable to send RTP on to the
BTS. It might be that the RTP payload provided in the MDCX is not
the one it will accept with the 0x05 mode. More work needs to be
done to understand this, that is the reason it is comitted to the
on-waves's branch instead of master.
|

|
|
Also, use this new function to dump lchan state on VTY and to
improve readability of RSL log messages.
|
|
This state will help us to differentiate between channels where we have
requested the release, and channels that are actually released.
|
|
In many cases we actually want a name / unique ID for the lchan,
not just for the on-air timeslot... especially in SDCCH/8 case,
where 8 SDCCHs share one timeslot...
|
|
|
|
When we allocate a channel, we send the RSL CHAN ACT REQ and wait until we get
a CHAN ACT ACK. Only the ACK will change the state, so there is a race where
we allocate that same channel to a different channel request before we get
the ACT ACK.
Introducing a new ACT_REQ state resolves this issue.
