MIH Signaling
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?
