Holger Hans Peter Freyther 33b9641025 bsc: Use the right string for the notification 2013-11-15 16:47:59 +01:00
Jacob Erlbeck aff2d62b8c bsc/ussd: Rename bsc_send_ussd_notification()
Rename this function to bsc_send_ussd_no_srv() since it's a rather
specialised function and not a generic USSD notification function.

Jacob Erlbeck b1250312ba bsc/ussd: Send faked CM Service Accept before sending USSD
The MS do not show the USSD messages yet. This patch modifies the
implementation to insert a CM Service Accept to finish the
establishment of the MM connection according to 3GPP TS 04.10/3.2.1
before the USSD notification is sent.

This fix has been tested with a Blackberry phone that has shown
an ussd_grace_txt after rf_locked has been set to '1'. Without this
patch, that message wasn't shown. The phone has sent a CC Setup
and other messages before processing the channel release message sent
by the BSC, but these messages have not been forwarded to the MSC (as
expected).

Jacob Erlbeck 36722e13da vty: Use vty_install_default() instead of bsc_install_default()
Remove ournode_exit_cmd, ournode_end_cmd, and bsc_install_default()
since this functionality is provided by the current libosmocore.

Replace calls to bsc_install_default() by call to
vty_install_default() with the following semantic patch:

    @rule1@
    expression N;
    @@
    - bsc_install_default(N);

Jacob Erlbeck cc391b8880 bsc: Add control command to set timezone
This adds a per BTS control command 'timezone' which expects a value
of the format '<hours>,<mins>,<dst>' or 'off' to set the value of
bts->tz. It has the same functionality like the existing VTY command
'timezone' in network/bts.

Jacob Erlbeck 946d1415c2 bsc/mminfo: Patch timezone and DST in MM Info messages
This adds in-place patching of the time information in the
MM INFORMATION message. The timezone in the 'Local time zone' and
the 'Universal time and local time zone' information elements
and the offset in the 'Network Daylight Saving Time' information
element are optionally set.

The new values are determined by the 'timezone' vty command in the
config_net_bts node. That command is extended by an optional
DST offset parameter.

Tests are provided for the vty part and for the plain
bsc_scan_msc_msg() function.

Jacob Erlbeck 56595f8647 ussd: Send USSD on call setup on MSC errors
Send an USSD message to the mobile station requesting a connection
for a call or a SMS when the link to the MSC is down or in the
grace period.

The messages can be set (and this feature activated) by setting
bsc/missing-msc-text resp. msc/bsc-grace-text via the vty.

The generation of both messages has been tested manually.

Jacob Erlbeck 0ae92a950a vty: Use generic 'end' and 'exit' commands
Add bsc_install_default() and replace all install_default()

This patch adds bsc_install_default() which calls install_default()
and add 'exit' and 'end'. All other calls to install_default() are
replaced by calls to bsc_install_default().

Since 'exit' and 'end' are now added automatically to each node, the
explicit registrations of these commands are removed by this patch,
too.

The related tests succeed now without work-arounds (except for the
'config' node itself which is part of libosmocore).

Holger Hans Peter Freyther c121bb3188 handover: Fix the handover signalling for IP based BTSes
This was reported by Kevin when he was testing handover. The problem
is the order of the signal handlers for S_ABISIP_CRCX_ACK. Right now
the handover signal handler is called before the one inside the libmsc
gsm_04_08.c. This means S_HANDOVER_ACK is signalled _before_ there is a
rtp socket created for the channel. The result is that the MDCX will
never be sent and the called will not be properly switched _after_ the
handover detection.

I do not want to play with the order of signal handlers, remove the
CRCX ack handling from the handover_logic.c and force the NITB (and
later the BSC) to check if the lchan is involved with a handover and
do the switching in there. This means right now we do what two signal
handlers did in one.

Reproduced and tested with the FakeBTS Handover test.
