Harald Welte 9575fd0732 [BSC] add example hopping config file for BS-11 in 2TRX config 2010-06-20 16:08:36 +02:00

laforge f87ebe69d5 [BSC] NM: Correct treatment of ARFCN_LIST for BS-11
For Siemens BS-11, the 'length' value of the ARFCN_LIST IE is interpreted in
violation of the spec.  The spec says it is a length in octets, while Siemens
treats it as 'count of 16bit ARFCN values'.

laforge 09108bff95 [BSC] RSL: properly include MA in IMM ASS CMD
When we build an IMMediate ASSign CoManD for a hopping channel,
we need to include the length of the MA in the total length of
the 04.08 message

Harald Welte c8794b5977 [BSC] SI: make sure we initialize the data field, not the bitvec structure 2010-06-20 10:44:54 +02:00
Harald Welte 9da921b8b0 add more executables to .gitignore 2010-06-20 10:44:54 +02:00
Harald Welte 29aca17ed0 [BSC] Hopping: Add MA IE to ASS CMD, IMM ASS CMD and HO CMD
Also, make sure the bit ordering in the pre-computed MA is correct,
as well as the cell channel description of the target cell being
present in the HO CMD.

Harald Welte 7401ae6a79 [BSC] Keep a SYSTEM INFORMATION cache for each BTS
This will later be useful for handover where we need to copy the cell
channel allocation into a normal 04.08 message

Harald Welte fd3708976a [BSC] Generate MA for each timeslot that has hopping enabled
The MA is used in 04.08 channel assignment related messages

Harald Welte c2fb3d0c3d [BSC] Make sure we only enable hopping on BTS that support it 2010-06-20 10:44:53 +02:00
Harald Welte f3d8e92731 [BSC] introduce the concept of 'BTS features'
We can then check if a bts supports a certain feature or not.

Harald Welte a39b0f2bb7 [BSC] Implement per-timeslot ARFCN lists for frequency hopping
We now compute the Cell Channel Description for SI 1 by bit-wise
OR of the ARFCN bitmask of each timeslot on all the TRX of the BTS.

Also, support generating a GSM 04.08 Channel Description IE for
the hopping case (with HSN/MAIO instead of ARFCN).

What's still missing now: Sending the 04.08 Mobile Allocation IE

Harald Welte 6e0cd04725 unfinished support for hopping channels 2010-06-20 10:44:52 +02:00
Harald Welte b37e5f8a60 [BSC] mISDN: Avoid sending RSL messages to wrong channel number
In some cases, we get a DL_INFORMATION_IND with a wrong channel
number, and only in the DL_ESTABLISH_IND we will see the real
channel number that is to be used for this (TEI, SAPI) tuple.

Harald Welte b88b6d3ea6 [wireshark] Major wireshark OML dissector
Now it properly parses message types and IEs that are defined different
depending on the BTS vendor / A-bis implementor.  This fixes a lot of
decoding bugs with Siemens BS-11 traces.

Holger Hans Peter Freyther f6d0e06940 bsc_api: Set the l3h header from within the dtap method
This is fixing USSD which broke when the code was

Holger Hans Peter Freyther 9764331062 bsc_api: Move gsm48_rcvmsg into the BSC API and dispatch.
The next step in the way to the BSC API. We have a clear a
new connection was opened signal now... and the MSC could
use it...

Holger Hans Peter Freyther 86481c29d4 bsc_api: Make paging/silent call work with the subscriber_connection
Do not use the lchan for the paging but operate on the
subscriber_connection, change the signals too to not carry
the lchan but the subscriber connection... the silent call
and vty code still assume there is a lchan inside the
subscriber connection.

Holger Hans Peter Freyther 77008464be bsc_api: Move BSC API between MSC and RSL code...
The lowlevel BSC paging API is a simple wrapper around
the RSL command. The BTS will automatically repeat these
messages but if we end up with two MSC inputs we will
need to count these messages somewhere...

Holger Hans Peter Freyther b2be195b50 bsc_api: Rename lchan_for_subscr to connection_for_subscr and update code
With handover and late/early assignment there might be two channels
for one subscriber and only the BSC knows which one to use, so use
the gsm_subscriber_connection everywhere...
2010-06-16 15:42:38 +08:00
Holger Hans Peter Freyther ea01ca764f chan_alloc: Make the lchan_find(bts,subscr) private/internal.. 2010-06-16 15:42:22 +08:00
Holger Hans Peter Freyther 0128843591 gsm48: Release the "operation" after sending out data...
* With an immediate release we would release the lchan
  before sending the data... change it.
2010-06-16 15:42:21 +08:00
Holger Hans Peter Freyther 228c1059fd bsc_api: Remove the lchan from the secure channel code...
The code still needs to stop touching the lchan directly
and put stuff into it.
2010-06-16 15:42:21 +08:00
Holger Hans Peter Freyther e9ed340425 bsc_api: Cut back on direct lchan usage. 2010-06-16 15:42:21 +08:00
Holger Hans Peter Freyther 667cdd60ca gsm_subscriber_base: Pass the subscriber as param to avoid crash.
The function we call will take the item from the list and do
the right thing.
2010-06-16 15:42:21 +08:00
Holger Hans Peter Freyther 280c768f91 gsm_04_11: Fix a crash... in case there is a already a connection
If there is a connection, return before paging... otherwise
we will delete the SMS twice.
2010-06-16 15:42:18 +08:00
Holger Hans Peter Freyther 1c6f394234 si13: Use the correct pseudo length for the SI13 message
The GSM04.08 Section 10.5.2.19 specifies the L2 Pseudo Length
and the length does not include rest octets, so we will need
to use a zero for the length.

The patch is coming from Dieter Spaar.
