Sylvain Munaut 98b53cba06 include: Add proper predeclaration for struct in mncc.h 
We use them, so declare them. (avoid including all gsm_data.h)

Sylvain Munaut 81a8bf1039 include: Small fixes to gsm_data.h 
We don't really need openbsc/gsm_04_08.h or abis_rsl.h
But we do need some definition from libosmocore

Sylvain Munaut e0b06b0293 bsc: Allow to configure Optional Cell Selection params from vty 
The default values are those where the parameters are encoded
as '0' and they're not output in the config file if that case

Holger Hans Peter Freyther 70c232f75a mid-call: Implement a timer to go from grace to off. 
Start the timer... switch it off when we do the final
tranistion by a command.

Holger Hans Peter Freyther bb62b3f053 mid-call: Rename ussd-grace to mid-call 2010-11-26 00:03:32 +01:00
Holger Hans Peter Freyther 625b6e4dab mid-call: Introduce a timeout to switch from grace to rf off. 2010-11-26 00:02:12 +01:00
Holger Hans Peter Freyther b4e72f881c bsc: Implement queuing of messages to the MSC before the con is established 2010-11-15 20:06:50 +01:00
Holger Hans Peter Freyther b79c3c97a2 bsc: The ip.access rtp-payload has no useful meaning 
Sending this as the RTP_PAYLOAD2 will produce a MDCX NACK
as we send the RTP_PAYLOAD in the CRCX. It does not seem to
be necessary to send anything != 0 for the RTP_PAYLOAD2.

Holger Hans Peter Freyther 620c2e678a bsc: Add thr audio module to send the MDCX message to the BTS 2010-11-15 20:06:50 +01:00
Holger Hans Peter Freyther 50c579b8c5 bsc: Implement the assignment command to the point of calling into the BSC API 2010-11-15 20:06:49 +01:00
Holger Hans Peter Freyther fae3c65938 bsc: Parse the cipher mode command and pass it to the BSC api. 2010-11-15 20:06:49 +01:00
Holger Hans Peter Freyther 863a55d44d bsc: Make bsc_queue_for_msc work on the osmo_bsc_sccp_con 
The gsm_subscriber_connection can die before the SCCP connection
so we should work on the osmo_bsc_sccp_con.
 2010-11-15 20:06:49 +01:00
Holger Hans Peter Freyther 3485feb49b bsc: Add module for handling BSSAP input 
The current implementation is a stub. The code from
bssap.c of on-waves/bsc-master will be migrated into
this new structure

Holger Hans Peter Freyther 00f4cc22c8 bsc: Implement closing the connections when the MSC goes missing 
Refactor the closing code of the CC timeout to a new function,
also make sure that the SCCP Connection is forced closed before
we destruct the connection for real.

Holger Hans Peter Freyther 7e9010892d bsc: Make open/close work on the sccp data 2010-11-15 20:06:48 +01:00
Holger Hans Peter Freyther b8781d2cd5 bsc: Start to open a SCCP connection and prepare timers and such. 2010-11-15 20:06:48 +01:00
Holger Hans Peter Freyther 9b17c769b9 bsc: Work a bit on opening the SCCP connection to the MSC. 
Most of the code is still stubs but the structure is a lot
cleaner than the one in the on-waves/bsc-master branch.

Holger Hans Peter Freyther 2a8675e49a bsc: Add a mobile country code setting for the backbone. 2010-11-15 20:06:48 +01:00
Holger Hans Peter Freyther 52d42abdb7 bsc: Implement scanning and changing messages from the MSC 
This will change the LAI of a LU accept message to the LAI
used for the on-air network. It will also detect when to
send a welcome ussd to the subscriber.
 2010-11-15 20:06:48 +01:00
Holger Hans Peter Freyther a54732d19d bsc: Add a method to scan messages coming from the MSC. 2010-11-15 20:06:48 +01:00
Holger Hans Peter Freyther d65305f5b4 bsc: Look for location updating requests in messages 
Introduce the SCCP connection data and remember that
we were seeing a location updating request from a
different LAC.
 2010-11-15 20:06:48 +01:00
Holger Hans Peter Freyther 5bb874d2f5 bsc: Add a hook where we can scan for LU and other messages. 2010-11-15 20:06:48 +01:00

Holger Hans Peter Freyther 8d380dcadd bsc_api: Change submit dtap to allow to automatically use the SACH 
For SAPI=3 on a TCH it might be nice to use the SACH to submit
the message. The api allows to automatically use the SACH if
a message like this is submitted.

Holger Hans Peter Freyther 2603c1f545 bsc_api: Clarify the parameters of the assignment command 2010-11-15 20:06:46 +01:00
Holger Hans Peter Freyther 2f169d64dd bsc_api: Make the cipher_mode take the 'include imei sv' argument 
The cipher mode command should enable encryption and send the
right RR message to the other side.

Holger Hans Peter Freyther 45b575fd94 bsc_api: The rr_cause is optional, pass it as a pointer 2010-11-15 20:06:46 +01:00
Holger Hans Peter Freyther 66dcd925c6 bsc_api: Nuke the clear complete from the API. 
There is no place where it can be called. Whoever is calling
the gsm0808_clear method should generate the clear complete
as the result.

Holger Hans Peter Freyther 46caa3048d bsc_api: Provide the link_id in the dtap callback. 2010-11-15 20:06:46 +01:00
Holger Hans Peter Freyther b094171c9f bsc_api: Add needed parameters to the assignment complete callback 
Provide the chosen channel and more information in the assignment
complete method.

Holger Hans Peter Freyther e1996f013c bsc_api: The cipher mode is not a message on the air interface 
The cipher mode reject will be send in case the BSC is not
able to support the requested cipher. So this reject can be
handled by however attempts to enable ciphering.
 2010-11-15 20:06:46 +01:00
Holger Hans Peter Freyther fce9307553 bsc_api: Change the cause to a uint8_t for now 
The RR Cause can only be one byte. Change from uint16_t to uint8_t for that.
 2010-11-15 20:06:46 +01:00
Holger Hans Peter Freyther 05c68841a8 bsc_api: Fix a use after free error in the Clear Request path 
The implementation of bsc_hack would call subscr_con_free before
the BSC API has had the chance to call gsm0808_clear to try to
release other channels. Fix that by adding a return value.

Holger Hans Peter Freyther 85334f1309 paging: Move the paging data into the paging.h 2010-11-15 20:06:45 +01:00
Holger Hans Peter Freyther 8dfd241bc6 subscr: Add method to find an active subscriber 
This is used by the paging code of the osmo_bsc. When we get
a paging response there should be an active subscriber with
the TMSI or IMSI and we can stop paging. There is no need to
allocate a new subscriber.
 2010-11-15 20:06:45 +01:00
Holger Hans Peter Freyther d740b688dc subscr: Add the subscr_get_or_create from the on-waves/bsc-master branch 
Create a subscriber based on a known IMSI, search the list of
active subscribers if there is already someone like this.
 2010-11-15 20:06:45 +01:00
Holger Hans Peter Freyther 928ca743db subscr: Move the TMSI reserved into the gsm_data 
Put it into the gsm_data.h to avoid requiring MSC code
in the BSC code paths.

Holger Hans Peter Freyther 8cc59036e6 rsl: Allow to hardcode the RTP Payload 
In case of a inflexible network it is better to hardcode
the rtp payload to a given type. E.g. when using AMR5.9 on
a TCH/F and TCH/H having the same payload is helpful. For
now this will be only used by the osmo-bsc.

Holger Hans Peter Freyther 4de1116356 bsc: Readd the core network code setting 
This will instruct the BSC to patch messages and replace
the old network code with the new one.

Holger Hans Peter Freyther bd7b3c5e45 mgcp: Introduce trans_bts and send BTS packets from this port 
Introduce the trans_bts. Right now only a port is allocated
and the packets from the BTS are sent from this socket.
