[Mobopts] IMS with 802.21 and MPA

[Carlos Rodrigues <cmjr at iol.pt>]

Hi!

I'm studying some aspects handover over heterogeneous networks, in   
particularly 802.21 and IMS "working" together. Like 802.21 can work  
as an application server connected to the S-CSCF, a MPA server can be  
attached to S-CSCF?
Or that must be "attached" to P-CSCF, the nearest point of access  
networks? (Or any of the previous solutions?)

Another question is about MIH-MPA on a dual mode terminal. The MPA  
only communicates with MIH or "links" too a higher layer (like IP)  
transport unit?

All help or support will be very helpful.
