Yes, I had read that. But even that does not really clarify it for me. Brian had said and you had agreed that:

I interpreted the the charter text as describing
deployment models like:

- Wi-Fi-based mobility management

- Cellular (e.g., 3GPP) mobility management

- Mixed technology mobility management




But, what exactly would go into, say, 3GPP mobility management? Are we going to describe how 3GPP system works? 
Would that be simply documenting 3GPP mobility in an IETF draft?

(Just FYI: It's not possible to gather what you are saying from reading the charter. Different people reading the charter may not have the same understanding. But like I said, this is just FYI, I can live with this text until we come back and refine it later).

Thanks.
