RE: MIH Signaling

How can a network entity inform the station to switch between links using the homogeneous mobility signalling? I can't figure out. You need in your MIH signalling some inter-medi handover instruction
What happen in homogeneous mobility in cellular networks for instance? The station is instructed to camp on a new cell/Node B. You can not use the same message to ask the station to camp to an AP. And further, it might not be the BSC/RNC that give the inter-media instruction

Hello 802.21 Folks,
Much has been mentioned about MIH Signaling in several proposals.
However many of us are still trying to get a clear understanding of this.
So some clarification would be preferable.
We already have support for Event Service(ES) and Information Service
(IS) in MIH. As part of these two services certain messages/packets get exchanged between station and network attachment point entity.
So as for MIH signaling:
1]Are any other type of messages/packets exchanged between station and network attachment points (apart from IS and ES)? What are these messages?
2] As part of MIH Signaling is there any other communication with higher/lower layers that is different than (IS/ES) messages/packets?
Also different networks may already support homogeneous mobility in certain way. For example 802.11 (with TGr support) primarily supports SISC (station initiated station controlled) handovers. 802.16 supports both (SISC and NISC (network initiated station controlled..etc.)) handovers, while cellular systems may have support for (NINC) type of handovers. As part of support for this homogeneous mobility these networks already have support for any L2 handover signaling that may be required.
For heterogeneous mobility, if (802.21) adopts a handover mechanism (SISC, SINC, NISC, NINC, etc.) for a network which is more in line with what may already be used by that network as part of homogeneous mobility, then we are more aligned with the general network architecture (for heterogeneous mobility as well) and may not need any new handover specific L2 signaling (apart from ES and IS messages/packets).
What do you folks feel about this?
