1. A method, implemented by a wireless transmit/receive unit (WTRU), for providing non-packet switched service in a target radio access technology (RAT) network, the method comprising:

  • receiving a circuit switched (CS) service notification message including an explicit indication that indicates an identity the WTRU is to use after performing an inter-system change from a source RAT network to a target RAT network, wherein the explicit indication includes at least one bit which has a bit value of one that indicates an international mobile subscriber identity (IMSI) of the WTRU should be used after the inter-system change is performed and a bit value of zero that indicates that a temporary mobile subscriber identity (TMSI) allocated for the WTRU should be used after the inter-system change is performed; and

    transmitting a paging response message including an identity identified by the explicit indication after the inter-system change is performed.
