Abstract  Abstract

PROBLEM TO BE SOLVED: To provide a method and apparatus for implementing a handoff between radio access networks (RANs) deployed under different radio access technologies (RATs).

SOLUTION: A wireless transmit/receive unit (WTRU) 150 is equipped with at least two radio units to support the RATs. Each RAN sends a list of co-located RANs in the coverage area of the RAN to the WTRU. The WTRU stores the list and determines whether a handoff criterion is met by one of the co-located RANs. The handoff is started when the handoff criterion is met by a target RAN or the WTRU transmits a measurement report to the current RAN and the current RAN determines whether the handoff criterion is met by a selected one of the co-located RANs and starts the handoff when the handoff criterion is met.
