Abstract

A method and system for switching a radio access technology RAT between two wireless communication systems (110and 120) with overlapping coverage area. RATwith multi-mode WTRU (102) can provide the same service in both networks. Each wireless system transmits an indication of inter-working wireless communication system. WTRU can receive the indication and initiate a handoff to the inter-working system to continue to receive the same service.
