Abstract: A method for delivering a short message service (SMS) message to an interworking wireless local area network user equipment (UE) (122) begins by registering the UE with an Internet Protocol short message gateway (IP- SM-GW) (118). A capability report is sent from the UE to the IP-SM-GW, the capability report including the capabilities of the UE. A SMS message is transmitted from a short message service center (SMSC) (104) to the IP-SM-GW. The capabilities of the UE are evaluated at the IP-SM-GW to determine whether the UE can receive the SMS message, and the SMS message is delivered to the UE via the IP-SM-GW if the UE has the capabilities to receive the SMS message.

Abstract: A method and system for interworking between cellular networks and wireless local area networks (WLANs) are disclosed. At least one cellular network, at least one WLAN and an IP network are deployed. A wireless transmit/receive unit (WTRU) first establishes a connection to a WLAN and a tunnel between an access point (AP) and a packet data gateway (PDG) is established. The PDG further establishes a tunnel to an IP network. The WTRU then invokes a service which is delivered through the WLAN. As signal quality from the degrades below a predetermined threshold, a handover from the WLAN to the cellular network is performed. A new connection to the cellular network may be established either before or after breaking the current connection to the WLAN or the two connections may be maintained simultaneously.

Abstract: A method for use in a wireless transmit/receive unit (WTRU). The method comprises generating a message indicating evolved universal mobile telecommunication systems (UMTS) terrestrial radio access network (E-UTRAN) capability information. The capability information includes an indication of support for an orthogonal frequency division multiplex (OFDM) mode and support for UMTS terrestrial radio access network (UTRAN) to E-UTRAN handover. The message is transmitted to a UTRAN base station on a UTRAN channel. A E-UTRAN service is received based on the message.

Abstract: A method and apparatus for handover of a dual mode wireless transmit/receive unit (WTRU) from an LTE system to a GERAN system uses measurements of the LTE and GERAN frequencies and a decision by a source evolved Node B to perform the handover. A GERAN access procedure includes PS attach messages exchanged between the WTRU and the target base station controller and a target SGSN. Alternatively, the GERAN access procedure uses RAN mobility information messages exchanged by the WTRU and the target base station controller and a relocation detect message by the source evolved Node B.

Abstract: Method and apparatus for delivering voice/data services within a piconet operating over a limited range or over a WLAN (1803) communicating with 3GPP devices by reformatting data into IP format before delivering to the WLAN (1803). The service is Short Message Service (SMS) (102). Upon receipt of the SMS message, relevant routing information is retrieved. A PDGW (1805) address for the SMS message is identified and sent to the PDGW address which identifies the WLAN user equipment (UE) (1801) for receiving the SMS and reformats the SMS message into IP format for delivery to the UE. A protocol architecture is provided for SMS delivery over WLANs, in particular, for UMTS/CDMA based SMS over WLAN (1803) through two alternative mechanisms: SMS tunneling and SMS proxy, for protocols for the delivery of SMS across the WLAN (1803).
