One of the requirements we have talked about is how does
the PaC realize that it is no longer connected to an access
network. This is required for reasons such as billing.
One of the possible solutions is to do a periodic ping
between the PaC and the PAA. If we do have such a scheme
then it is possible to discover that the PaC is no longer
connected to the PAA which may force it to a PAA Discovery.
