3. Introduction
An example handover flow chart for the / use case
Handover from WLAN (802.11) to WMAN (802.16)
The flow chart is based on the template handover flow chart: Template_for_Handover_Flow_Diagram.ppt
MAC-S/MAC-C are replaced with / MAC
POAs are replaced with AP(.11)/BS(.16)
Naming of Handover-initiate/prepare/commit/complete is still based on D2.0.
The names of the message will be updated in the next version D3.0.
