21-06-0501-02-0000 IEEE 802.21 MEDIA INDEPENDENT HANDOVER DCN: 21-06-0501-02-0000 Title: Amendments for Event Register Date Submitted: July, 10, 2006 Presented at IEEE 802.21 session #15 in San Diego Authors or Source(s): Zhuang Hongcheng ， Zhang Jietao Abstract: This document proposes an amendment for event register. MIH users can take more appropriate actions according to the result codes when event register succeeds or fails.

21-06-0501-02-0000 Background and Problem Background Higher layer entities can register to receive event notifications from a particular event source. These services facilitate Mobile terminal or Network controlled handover. Problem In the register process, it is possible that some events couldn’t be registered correctly, but there are no primitives or methods to notify MIH user about the failure reasons in the current draft standard. For example, link event register maybe fail because of disappearance of the event source or other reasons.
21-06-0501-02-0000 Amendment of MIH_Event_Register.response Primitives (1) Section 220.127.116.11 MIH_Event_Register Response The response indicates which of the event types were successfully registered or why they were registered unsuccessfully.
