3 Technical Issues regarding MIH Registration
between MIHF in MN and MIHF in a serving network. between MIHF in a serving network and detected network. Deregistration Re-Registration procedure…

4 Re-Registration – What?
A mechanism between peer MIHF entities to indicate that the MN is still registered to the network. The difference between registration and re-registration Registration establishes a new session; a new Session ID is created; Re-registration refreshes an existing session; no need to create a new session ID

5 Re-Registration – When?
Two cases: When the information pertaining to the joined POA has changed E.g., POA changes due to homogeneous handovers Periodic transmission (lifetime of a session) The MN determines that the peer MIHF is still available using the currently established lower layer connection.

6 Re-Registration – Proposed Texts
The related texts in D2.0 Section , pp.93, line#29: ‘Re-Registration scope to be defined. Comment #266 to propose the primitives for MIH Re-registration Remedy #3 in contribution Key points: existing session ID in the semantics of requests Comment #378 to propose the messages for MIH Re-registration Remedy #4 in contribution

7 Other Amendments Comment #215 to propose texts for section 6.4.4
Remedy 1 in contribution Comment #267 to add Session ID in the deregistration primitives.

8 Other Issues to be discussed
The indication and confirm primitives shall be added. Abnormal cases in MIH registration shall be considered: Registration failure cases, e.g., registration rejected. Lifetime expiry for active sessions Link layer failure due to unreliable lower layer links
