IEEE MEDIA INDEPENDENT HANDOVER DCN: Title: Amendments for Event Register Date Submitted: July, 10, 2006 Presented at IEEE 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.

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.
