<P>PROBLEM TO BE SOLVED: To provide methods for reducing the amount of time required to complete a handoff in a system which uses different frequency bands. <P>SOLUTION: A mobile station sends a handoff request to a current BS sector, which forwards the request to a new BS sector. The new BS sector processes the request assigning dedicated resources, e.g., dedicated resources to an identifier, and dedicated uplink segments to an identifier. Information identifying the allocated resources is conveyed to the mobile station. The mobile station determines the time of the allocated dedicated segments on the basis of a received beacon signal from the new BS sector with given timing relationships to dedicated segments. The mobile station breaks an original wireless link just prior to the time of the first assigned dedicated segment. The mobile station communicates information on the assigned dedicated segments to perform registration operations, e.g., timing synchronization and power control, establishing a new wireless link. <P>COPYRIGHT: (C)2013,JPO&INPIT |
