Re: [802.21] IMS with 802.21 and MPA

[Carlos Rodrigues <cmjr@iol.pt>]

But (the MPA server) can be attached to S-CSCF, like 802.21 as  
application server, no?

And in the client? Communicates with MIHF and a higher layer transport  
unit (e.g. IP based), right? (as presented in the image)

Yes, it is based on MPA draft that is under IRSG review right now.
The paper would be accessible publicly around the conference time.

If you read the MPA draft, ideally the MPA server should be closer to
the edge of the network, thus in this case, closer to P-CSCF, if you
have the P-CSCFs in a distributed manner.
