Description of behavior MN has 3 ways to perform signaling: a. via serving network proxy function – via target network proxy function – target PoA b. via target network proxy function – target PoA

Signaling c. In dual-radio handover, MN would use existing target network L2 frame to perform handover signaling with target PoA a and b: MN behaves as if c. MN may or may not know which target PoA or which target network MN may query Information Repository, MIH_MN_HO_CANDIDATE query, etc. MN uses SR-MIHF frame to carry L2 frame payload to a proxy function

Proxy function behavior a. The SR-MIHF frame from MN sends to the serving proxy function which will (1) find a target network (2) signal with target network proxy function b. The SR-MIHF frame (from either MN or serving network proxy function) to the target network proxy function which will (1) find the target PoA (2) signal with target PoA

Proxy function behavior Proxy function signals with target PoA using (1) SR-MIHF frame with the target network L2 frame (2) any other mechanism outside this spec

SR-MIHF SR-MIHF is an extension of the functionalities in MIHF The group suggests to avoid introducing SR- MIHF, but describe in the introduction, that this amendment defines additional primitives and message extensions to perform single radio handover
