Abstract:
PROBLEM TO BE SOLVED: To provide an improved method and an apparatus for location tracking and paging. SOLUTION: An inactive-state mobile node updates its location information by transmitting a first message via a radio link to an access node. In response to the first message, the access node generates a second update message. The second message includes a mobile node identifier. The second message is received by a tracking agent. The tracking agent updates location information corresponding to the mobile node. When a route of the second message is specified by the mobile node as a form of an IP message using a mobile IP, the route of the second message is specified for a last network attachment point of the mobile node by a mobile IP home agent. Then, the tracking agent is stationed at the last point and interception of the message is performed. COPYRIGHT: (C)2011,JPO&INPIT
Abstract:
PROBLEM TO BE SOLVED: To provide a management node that stores state information associated with an end node. SOLUTION: The management node 400 for storing state information includes: an interface 420 which receives and transmits the state information associated with the end node; a processor 404; and a memory 410, coupled to the processor, for storing the state information and a computer-readable instruction. When the management node 400 receives the state information, the management node determines whether the state information stored in the memory 410 should be updated, and overwrites the state information with latest state information when it is determined that the state information should be updated.

Abstract:
PROBLEM TO BE SOLVED: To provide an access node that provides communication of state information associated with an end node. SOLUTION: The access node 300 for providing communication of state information includes: an interface 330 which receives a request message from the end node; a memory 310 which stores the latest state information associated with the end node; and a processor 304 coupled to the memory. When the access node 300 receives the request message from the end node at the interface 330, the processor 304 retrieves the latest state information associated with the end node from the memory 310, generates an update message including an end node identifier, the latest state information, and a time stamp based upon the request message, and transmits the update message to a management node, which updates the state information of the end node.

Abstract:
PROBLEM TO BE SOLVED: To provide group communications methods and apparatus for conserving resources. SOLUTION: A multicast operation is supported with transmission characteristics, such as transmission power level, coding rate, and/or modulation method being selected to reliably communicate information to end nodes in the group. Thus, resources can be conserved by matching transmission requirements with information on requirements of one or more group members. The requirements for reliably reaching the end node with the worst channel conditions can determine the group transmission requirements. Also, the requirement can be used for determining the group transmission requirements, and power level and other transmission resource allocations can change in response to changes in group membership and/or conditions corresponding to existing group members.

Abstract:
Un procedimiento para controlar los estados de recursos de calidad de servicio con respecto a un terminal, que comprende: recibir (404), en una estación base, una primera petición relacionada con la calidad de servicio, QoS, con respecto a un abonado de un primer solicitante; caracterizado por los pasos de: recibir (406), en la estación base, una segunda petición relacionada con la calidad de servicio con respecto al abonado de un segundo solicitante, en el que al menos uno de los solicitantes está en un lado del operador de red de un enlace de acceso; controlar los recursos de calidad de servicio con respecto al abonado basándose en los parámetros de QoS definidos dentro de la primera y segunda petición, en el que al menos una de las peticiones primera y segunda comprende peticiones de calidad de servicio con respecto a al menos un flujo de tráfico particular, recibir, en la estación base, una tercera petición de un dispositivo en un lado del abonado del enlace de acceso que indica que el tratamiento de calidad de servicio para proporcionar al abonado debe actualizarse; y proporcionar tratamiento de calidad de servicio al al menos un flujo de tráfico asociado con el abonado basándose al menos en parte en la tercera petición.
Abstract:
Wireless terminals and base stations support multiple modes of dedicated control channel operation wherein wireless terminals are allocated different amounts of dedicated uplink resources for reporting control information. A set of dedicated control channel segments is utilized by a wireless terminal to communicate uplink control information reports to its serving base station attachment point. Full tone and split-tone modes of dedicated control channel operation are supported. In full tone mode, a single wireless terminal is allocated each of the dedicated control channel segments associated with a single logical tone. In split tone mode, dedicated control channel segments associated with a single logical tone are allocated between different wireless terminals, with each of the multiple wireless terminals receiving a different non-overlapping subset of the dedicated control channel segments. Logical dedicated control channel tones can be dynamically reallocated for full-tone mode use or split tone mode use.
