ABSTRACT:
A Handover method in a mobile WiMAX network includes sending a list of target BSs for possible HO acquired by an MSS to a serving BS; providing, at the serving BS, a HO request to the target BSs in the list along with an unique identifier identifying the MSS to collect association responses from the target BSs; providing, at the serving BS, the association responses along with the unique identifier to the MSS so that the MSS performs scanning and ranging processes; performing resource reservation for possible HO at the target BSs; setting up service flows at a target BS selected among the target BSs; bi-casting data from the serving BS to the MS and the selected target BS before the connection break with the serving BS; and performing, at the MSS, an initializing procedure to connect with the selected target BS as a new serving BS.
