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)
