Abstract  Abstract

Techniques for providing packet switching service to the target radio access technology (RAT) network method and device. wireless emitting/receiving unit (WTRU) receiving a circuit switched (CS) service notification message. if the WTRU has been assigned a temporary mobile subscriber identification (TMSI) effectively the changing is performed after transmitting TMSI effective response message comprising paging between systems from a source RAT network to a target RAT network. CS service notification message is for terminating a CS call request. source RAT network may be a long term evolution (LTE) network and a target RAT network may be a third generation partnership project (3GPP) network. Alternatively if the WTRU is not allocated a valid TMSI then changed the system after transmitting the identification of the WTRU international mobile subscriber identification (IMSI) paging response message.

A method and apparatus are described for providing non-packet switched service to a target radio access technology (RAT) network. A circuit switched (CS) service notification message is received by a wireless transmit/receive unit (WTRU). If the WTRU has been allocated a valid temporary mobile subscriber identity (TMSI) a paging response message including the valid TMSI is transmitted after an inter-system change is performed from a source RAT network to a target RAT network. The CS service notification message is for terminating a CS call request. The source RAT network may be a long term evolution (LTE) network and the target RAT network may be a third generation partnership project (3GPP) network. Alternatively if the WTRU has not been allocated a valid TMSI a paging response message including an international mobile subscriber identity (IMSI) that identifies the WTRU is transmitted after the inter-system change.
