Take the timeouts from the struct.
|
|
|
|
|
|
Start a timeout to wait for the CC of the network and if it does
not come in time we will abort the connection and take down the
allocated lchans.
|
|
Be able to tune the RACH settings of the BTS via the vty interface,
by default they are initialized to -1 which means we will use the
content of the static array (BTS default) and can be changed via
the VTY interface. I have verified the setting on the nanoBTS with
wireshark and I have tested writing the config file.

|
Only page if we have a load that is acceptable for paging. This
option is off by default, and can be enabled per bts. The idea
is that when we have no resources right now we will not page as
it will only create more RACHs and increase the load.

|
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.

It might be that we run down to zero available slots but the BTS
might not send us a load indication. This can happen if we think
we send paging requests and the BTS disagrees and considers them
as errors and does not count the paging message.
When we drop to zero we will start a credit timer to give us extra
credit after six seconds, if we get a CCCH load indication before
we will stop the timer.

This causes some config file breakage but sounds like a much cleaner
approach than to have two separate config variables for this.

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.

The current code was overly complex. It tried to iterate over
the list in a round robin and we had to keep track of the last
element, see if we remove that one, check if the list becomes
empty... This can all replaced by treating the double linked
list as a queue. We take the item at the front, do something
on it and then and then put it back to the list at the end.

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 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.
|
|
Keep track of SCCP connections so we can clear them
when the MSC is going down.
|
|
Remove further usage of lchan from the gsm 04.11 bits
|
|
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.
|
|
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.
|
|
Keep a static version as the shell script is not dealing well
with branch tags/names containing text.

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"

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
|
|
We will use this token to identify us at the MSC for
now. This assumes that something like OpenVPN is already
used to secure the networking. In the future we will
explore using TLS for the communication and certificates
for the authentication.
|
|
In case we need to handle speech but we are currently on a SDCCH
we need to assign a new channel and close the old one. This
implementation should have the correct flow of things but we might
need to fix some error situations properly.
It is implemented by keeping a secondary_lchan pointer that will
be swapped into the lchan pointer after the assignment complete
message from the MS. The old lchan will be deactivated (the SACCH
should stay open). We have to manually remove the subscr from the
lchan structure to properly close things down.

Some NM attributes are defined differently depending on
the BTS type. Having one big nm_att_tlvdef[] table for
all BTS types is no longer sufficient. This patch
* introduces 'struct gsm_bts_model' to describe a BTS model
* adds definitions of gsm_bts_model for BS-11 and nanoBTS
* changes the abis_nm_tlv_parse() function: include a bts pointer

-1 is assigned in case the variables are not set. This means
it must be a signed type (as the comment says), now really use
a signed type.
|
|
* Be able to have a country code in the air but use a different
country code when talking to the core network.
* Now both country and network code can be different on air and
on the MSC communication.
|
|
* Make it possible to have a different MNC in the RSL traffic
than in the core network.
* Introduce the "core network code NUMBER" variable. If it is
set this network code will be used in traffic with the MSC.
* Use the core_network_code number when sending a packet to
the MSC
* Regenerate the LAI (this is where I could have a bug) when
sending packets to the BTS.
* Add size checks.
This is not tested, I might got something wrong.

This enables us to reliably detect if a lchan is part of a silent
call or not.
