Description

So far the SGSN only supports paging a single cell, but no Routing Area, as it doesn't tracks PCU's.
Implement PS paging by having a PCU object (and even further another FSM).

The problem is the SGSN only tracks the BVCI for a MS atm. So every PCU must cover it's own RA to have the SGSN propertly working.

some backgroud, for the record:

In most 'commercial' networks out there, the PCU is BSC-colocated and hence the PCU coverage area
is likely much larger than Routing Areas, so you would normally expect to have many RA per PCU, and hence
per signaling BVC.

For the p-t-p BVCs, one of course has one BVC per Cell (BTS) even in that situation.

AFAIR, paging can happen both on the signaling BVC and on the p-t-p BVC.
