Abstract  Abstract

PROBLEM TO BE SOLVED: To provide a method for implementing a fallback procedure from a packet switched (PS) radio access technology (RAT) to a circuit switched (CS) RAT.

SOLUTION: A paging message is received at a wireless transmit/receive unit (WTRU) via the PS RAT the paging message including a WTRU identifier and a domain indicator the domain indicator indicating whether the paging message is related to a service on the CS RAT. If the WTRU identifier in the paging message matches a stored identifier of the receiving WTRU then a fallback procedure to the CS RAT is performed. The WTRU responds to the paging message using a CS RAT-based identifier assigned to the WTRU.
