The fast handover method of Relay Station based on priority message

Developed a fast handover method based on channel quality messages associated with the priority messages in mobile multi-hop relay networks. The Relay Station (RS) and attached all terminals can complete the fast handover in fixed, nomadic, mobile relay station, when add / remove relay station in the existing network, and add / remove relay station, in the existing communication path, through environmental monitoring and Ranging, as well as the new relay station login / login again. Furthermore, To ensure that the channel quality of the communication path after the fast handover, and significantly reduced delay and complexity of handover procedures of the scanning, environmental monitoring and ranging.
