Motivation An example to capture current understanding of MIH interworking with IP mobility signaling Intent is to utilize the flow for following purposes, to identify Any superfluous functionality Any missing functionality How do we deal with superfluous functionality? May be there are other IP mobility mechanisms that may find it useful But, mechanisms that already has this functionality should not be forced to use it Logical approach is to make them optional for efficient interworking related to known mobility mechanisms Two flows are shown a) MN Initiated b) Network Initiated
