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 least 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: Apparatus and method by which Internet Protocol (IP) traffic can be transferred (i.e. handoff) between two different terminals operating according to two different technology standards in two different systems with two different IP addresses. For example, a session handoff can be made between a terminal in Wireless Local Area Network (WLAN) a terminal in a 3GPP UMTS or between a terminal in CDMA2000 and a terminal in a 3GPP UMTS. These terminals can be either physically separate entities or logical entities that are encapsulated within a common enclosure.

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 method and system for supporting an evolved universal mobile telecommunication systems (UMTS) terrestrial radio access network (E-UTRAN) are disclosed. The system includes a wireless transmit/receive unit (WTRU), a UTRAN and an E-UTRAN. The UTRAN sends to the WTRU a list of available radio access technologies in a coverage area of the UTRAN. The list includes information related to the E-UTRAN. The WTRU receives the list and may initiate a handoff based on the list. The WTRU then sends its multi-mode/multi-RAT capability information including the E-UTRAN capability to the UTRAN. The UTRAN then sends a measurement capability message to the WTRU. The measurement capability message includes parameters necessary for performing measurements on an E-UTRAN channel. The WTRU performs measurements based on the measurement capability message and reports measurement results to the UTRAN. The UTRAN may initiate a handoff to the E-UTRAN based on the measurement results.

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: Un sistema de comunicacion inalámbrica que incluye al menos una unidad de transmision y recepcion inalámbricas de multiples pilas (UTRI) de 802 de IEEE y una pluralidad de redes de acceso tecnologicamente diversificadas, tales como las redes 802.X de IEEE y redes de Proyecto de Asociacion de Tercera Generacion (PA3G), que están actualmente desplegada. Tanto las UTRI de multiples pilas como las redes de acceso tecnologicamente diversificadas incluyen una funcion de transferencia independiente de medios (TIM). La UTRI está configurada para leer informacion de TIM transmitida desde una de las redes de 802.X de IEEE, activar los procedimientos de autenticacion y autorizacion de PA3G basados sobre la informacion de TIM, obtener una direccion de protocolo de Internet (IP) local, establecer un canal hacia una interfaz de datos en paquetes (IDP) en una red de nucleo de PA3G,construir una atencion de direccion (AdD) y registrar la AdD con un agente domiciliario de la UTRI, con lo cual los datos destinados a la UTRI es canalizado por el agente domiciliario a través de un nuevo canal establecido entre el agente domiciliario y un agente externo basado sobre la AdD..

Abstract: A method and system for reporting evolved universal mobile telecommunication systems (UMTS) terrestrial radio access network (E-UTRAN) capabilities are disclosed. A wireless transmit/receive unit (WTRU) sends a first message to a core network (CN) to report the E-UTRAN capabilities of the WTRU. The CN then updates the WTRU capabilities based on the first message. The first message may include a radio access capability information element (IE) which carries information related to E-UTRAN capabilities of the WTRU and/or a network capability IE which carries information regarding network capabilities of the WTRU. The CN may send a second message to the WTRU to report network capabilities with respect to the radio access networks (RANs) to which the core network is connected and services that can be provided over the E-UTRAN.

Abstract: A method and apparatus for implementing a handoff between radio access networks (RANs) deployed under different radio access technologies (RATs) are disclosed. A wireless transmit/receive unit (WTRU) is equipped with at least two radio units to support the RATs. Each RAN sends a list of co-located RANs in the coverage area of the RAN to the WTRU. The WTRU stores the list and determines whether handoff criteria is met by one of the co-located RANs. The WTRU then initiates a handoff from a current RAN to a target RAN if the handoff criteria is met by the target RAN. Alternatively, the WTRU may send a measurement report to the current RAN, whereby the current RAN determines whether handoff criteria is met by a selected one of the co-located RANs and initiate a handoff to the selected RAN if the handoff criteria is met.
