    Abstract: Method and apparatus for providing a solution to the handoff problem includes negotiation of new media codes (coders/decoders) for utilization in cases where the two devices involved in the handoff are incompatible. Although mobile IP (MIP) is presently utilized to perform handoff procedures, this technique lacks a trigger mechanism to initiate handoff between two different devices which communicate with two different networks or one common network. In addition, MiP does not address the issue of compatibilities between media types, codes and supported bit rate. The handoff utilizes a session protocol (SIP) message for handoff. 0) M co w r &h oz CE 5 2 f-5 Cc LUI cC3 w3 I-L ~g3I LU oL P-UP- LU Cr. c: 0 D LU 00 u0 C ce) C) _ c 7n LUI w LO LO C-I co CQ co LU L= LUJ CLJ !

    Abstract: A method and system for controlling access to a medium in a wireless communication system. A superframe structure is defined in time domain to include a contention free period (CFP) which has at least one scheduled resource allocation (SRA), at lease one management SRA (MSRA) and a contention period. An extended beacon (EB) including information about the SRA and MSRA is transmitted for. The MAC architecture reduces station battery consumption, supports higher throughput for non-real time (NRT) traffic and is more efficient for real time (RT) traffic while maintaining full compatibility.

    Abstract: A method for delivering a short message service (SMS) message to an interworking wireless local area network user equipment (UE) begins by registering the UE with an Internet Protocol short message gateway (IP-SM-GW). 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) 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 performed by a WTRU may comprise transmitting a request for attachment to a base station. Authentication may be performed between the WTRU and a cellular core network node of a cellular core network, via the base station. The method may further comprise transmitting a registration request to the cellular core network via SIP over an IMS and transmitting a SIP message indicating a capability of the WTRU to receive data messages via the IMS. The WTRU may receive, in accordance with the capability of the WTRU to receive data messages via the IMS, at least one data message, from the base station, via the IMS. The data message may be displayed on a display of the WTRU.

    Abstract: A wireless communication system and method of implementing an evolved system attachment procedure are disclosed. The system includes a first core network and a second core network which is evolved from the first core network. A wireless transmit/receive unit (WTRU) sends an attach request message to the second core network. The second core network activates a packet data protocol (PDP) context and sends an attach accept message to the WTRU. The attach accept message includes information regarding the PDP context. The second core network constructs a session and mobility management (SMM) context for session management (SM) and mobility management (MM) for the WTRU.

    Abstract: A method includes receiving internet protocol (IP) multimedia core network subsystem (IMS) session content that includes voice call content in IMS domain and multimedia content in IMS domain; translating the voice call content in IMS domain to voice call content in circuit switched (CS) domain; transmitting the voice call content in CS domain to a wireless transmit/receive unit (WTRU) via a CS domain entity and a radio access network (RAN); and transmitting the multimedia content in IMS domain to the WTRU via a PS domain entity and the RAN.
