    Abstract: PROBLEM TO BE SOLVED: To provide a more effective scheme for higher-quality broadcasting and a scheme for much more economical utilization of a communication resource, in a method and an apparatus for performing enhanced file distribution in a multicast and a broadcast. SOLUTION: A user can access a file for the broadcast in a communication system for providing a broadcast service. Contents of the file for the broadcast, which are required to process the broadcast file, are differently transmitted from those of file attributes. Through such arrangement, more effective download and processing can be expected in the broadcast file by receiving the file attribute earlier than the contents file. COPYRIGHT: (C)2011,JPO&INPIT

    Abstract: PROBLEM TO BE SOLVED: To provide an inter-system handover system that efficiently supports hand-down and hand-up to different radio access technologies.SOLUTION: Latency and handover connection failures are reduced by an access node (nodeB) broadcasting information about a neighboring system (target) when a UE 12 reception (RX) capability is both inside and outside a reception range of the neighboring system. A optimized list of neighboring RAT systems (targets) are broadcast from a network, including measurement parameters and reporting instructions. Thereby, reporting driven by the UE 12 minimizes the latency. The UE 12 reports other-system searches to network only if needed for a handover. In addition, handover requests can be bundled with other system measurement information, if necessary, for additional efficiency.

    Abstract: An inter-system handover system for a wireless communication system supports hand-down and hand-up of user equipment (UE) to different radio access technologies, including synchronous and asynchronous systems. Latency and handover connection failures are reduced by an access node (nodeB) broadcasting information about neighboring systems (targets) when the UE reception (RX) capability is both inside or outside the reception range of the target. A single RX chain is sufficient, although transitioning between a wireless wide area network (WWAN) to a wireless local area network may (WLAN) may advantageously benefit from simultaneous operation on two Rx chains. Optimized list of neighboring RAT systems (targets) are broadcast from the network, including measurement parameters and reporting instructions. Thereby, UE-driven reporting minimizes latencies. UE reports other-system searches to network only if needed for a handover. In addition, handover requests can be bundled with other-system measurement information, if necessary, for additional efficiencies.

    Abstract: Techniques for performing handover in order to maintain call continuity for a user equipment (UE) are described. The UE may communicate with a first cell in a radio access network (RAN) for a packet-switched (PS) call, e.g., for Voice-over-Internet Protocol (VoIP) via High-Speed Packet Access (HSPA) in W-CDMA. The UE may send measurement reports to the RAN and may receive trigger from the RAN. The UE may establish a circuit-switched (CS) call with the first cell while the PS call is pending at the first cell. The PS call and the CS call may be for a voice call, and the UE may switch data path for the voice call from the PS call to the CS call and then terminate the PS call. The UE may then perform handover of the CS call from the first cell to a second cell, which may not support VoIP.

    Abstract: Un sistema para transferencia intercelular entre sistemas para un sistema de comunicaciones inalámbricas soporta transmisión descendente y transmisión ascendente del equipo del usuario (UE) para diferentes tecnologías de acceso por radio, incluyendo sistemas síncronos y asíncronos. Los fallos de conexión de latencia y transferencia intercelular se reducen mediante un nodo de acceso (NodeB) que radio difunde la información acerca de los sistemas contiguos (blancos) cuando la capacidad de recepción del UE (RX) es tanto hacia dentro como hacia fuera del margen de recepción del blanco. Una cadena RX individual es suficiente, aunque una transición entre una red de área amplia inalámbrica (WWAN) hacia una red de área local inalámbrica (WLAN) se puede beneficiar ventajosamente de la operación simultánea en dos cadenas Rx. La lista optimizada de los sistemas RAT contiguos (blancos) se radiodifunde desde la red, incluyendo los parámetros de medición e instrucciones de reporte. Con esto, el reporte conducido del UE reduce al mínimo las latencias. El UE reporta las búsquedas de otros sistemas a la red sólo si es necesario para una transferencia intercelular. Además, las peticiones de transferencia intercelular se pueden empaquetar con la información de medición de otros sistemas, si necesario, para eficacias adicionales.
