Abstract  Abstract

A wireless transmit/receive unit (WTRU) supporting Long Term Evolution (LTE) to perform circuit switched (CS) fallback is provided. The WTRU may receive via a packet switched (PS) radio access technology (RAT) a paging message including an International Mobile Subscriber Identity (IMSI). The paging message may have a domain indicator indicating that the paging message is from a CS network. The WTRU may fallback to CS and subsequently use the IMSI.
