It was possible that the tmp was strduped but not freed, e.g. when
the number of commas was not right. It would evenutally be freed at
the time the cmd is freed thanks to the talloc hierachy.
Katerina pointed out that some nodes are not fully documented and
proposed some messages. The token/timeout messages were correct, I
have modified the other messages. I removed the full-stop from the
PING/PONG documentation as we are normally not using a full sentence.
The RF lock excluded BTS was not paged at all. Now forward the
paging message to the handler and call a function that will check
if this LAC can be paged right now. Introduce a new paging method
that allows to page on a dedicated bts, refactor the code to use
this method for paging.
When introducing the exclude for the BTS lock the RF stayed up but
all connections were immediately released. Optionally pass the BTS
as second parameter and check the exclude bit.
Tested-with: rf-lock-exclude/RFLockExcludeTest.st
For short IP failures we want the RF to stay up and wait for
the re-connect but in case the A-link is gone too long it is
good to switch off the RF and wait for commands to enable it
again.
Handle the mr_config request and set the AMR multirate config for
the given MSC. Initialize the mr_config with the AMR5.9 default we
have been using until now.
When we are asked to route calls on a local link and
the link is not available we would crash when trying
to send a packet over a deadline. When we have decided
to move a connection it is guranteed that the current
SCCP connection will vanish, we either migrate to another
MSC or the RSL/subscriber connection will be closed.
Inspect the CC Setup messages and if the dialed number is matching
the regexp of the local MSC the connection will be rerouted. The
original MSC will get a GSM0808 CLEAR REQUEST, a new connection with
a CC Setup message will be opened.
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.

Inspect the message and see if it is a paging response,
then try to find the MSC that has paged this subscriber
and select this as the target MSC, also move the MSC to
the back of the list for 'load balancing'.
The first fields are still the location up to the height.
The next field is "operational" if any of the trx are operational,
otherwise "inoperational"
The second to last field contains "locked" if all of the trx are in the
admin state, otherwise "unlocked".
The last field represents the rf policy currently in effect. It is one
of (on|off|grace|unknown).
<tstamp>,<valid>,<lat>,<lon>,<height>,<oper>,<admin>,<policy>
The ip.access nanoBTS has issues if the admin changes are called
too often in too little time. This will lead to a situation where
the site manager will fail to start properly. Remove the TRX code
as the RF Control class does not support setting this per TRX.

Some nodes below 'config' didn't have ournode_exit / ournode_end,
and thus were not able to properly perform this function. exit should
always only go back one level, while end drops us back to ENABLE_NODE.
The prompt now represents the nesting level, and there's one consistent
space after the final prompt character (typically #).
