RE: [Seamoby] CAR Discovery Requirements

Hi John,

I'm kind of confused by your comment. Are you questioning
the inter-domain handoff or the discovery? Why do I have to
resolve which users are subscribers of which domains if I want
to discover ARs in my proximity?

We're discussing CAR discovery. I don't see your policy
interactions, inter-domain roaming, and billing problems in this
context. However, it is certainly an issue for the actual selection of
the
target AR, but TAR selection is not within the scope of the
CAR discovery protocol.

Regards,

Dirk
