real BSC.

Holger Hans Peter Freyther eef86b5d59 [bsc_msc] Move the connect to the MSC routine into a new file 2010-06-15 20:24:05 +08:00
Holger Hans Peter Freyther 9e2c5f572a [bsc-nat] Start with a simple NAT/MUX for a BSC 
Harald actually pointed out that this feature is just NAT. We want
to connect n-real BSCs to one BSC Mux. We will talk the ip.access
protocol and SCCP over of this link.

The mux will drop certain GSM messages (like the reset), it will
replace source local reference (NAT functionality) and it will handle
some GSM08.08 specially.

Get the thing started...

transaction.

Holger Hans Peter Freyther 9c595b7474 bsc_api: Implement transparent RLL establishment and SAPI n REJECT 
When submitting a DTAP message, the BSC API will attempt to
establish the RLL layer and then send the message or send an
SAPI n REJECT. This will be used by the SMS code.

This will take care of the auth/check/enable cipher sequence
and call a callback function when done.

Currently the negotiated Kc is saved but not re-used, so
there is an authentication each time ...

Sylvain Munaut c614a6a199 db: Rename AuthTuples to AuthLastTuples 
Ultimately, we'll need to store both the last used tuple by a
subscriber and a list of known tuples (for unknown Ki). What's
currently implemented for AuthTuples is the former behavior, so
reflect that.

The second use case will be added as a separate table with separate
accessors later on.
