Abstract: Methods and apparatus for routing messages between an end node and an access node via another access node are described. Physical layer identification information is used when identifying a remote, e.g., adjacent, access node as a message destination. Thus, when a connection identifier based on one or more physical layer identifiers is available to a wireless terminal, e.g., from one or more downlink signals received from a destination access node, the wireless terminal can use the connection identifier corresponding to the destination node to route a message via an access node with which it has an established uplink connection. Such connection identifier information can be used even when other addressing information, e.g., network layer address information, associated with the destination access node, may not be available to the wireless terminal.

Abstract: Systems and methodologies are described that facilitate Mobile IP home agent (HA) discovery in a wireless communication system. Discovery of a HA for Mobile IP can be conducted as described herein for a mobile terminal located on a network wherein movement of the terminal is managed by a network-based mobility protocol. For example, various aspects described herein can be utilized for discovery of a HA located in a 3GPP network from 3GPP and/or non-3GPP access. Further, various aspects described herein can be utilized to discover a gateway acting as mobility anchor for a network mobility protocol utilized by the network. As additionally described herein, HA discovery can be conducted in connection with DNS query formation and communication, network attach and/or re-attach procedures, Neighbor Discovery signaling, and/or other procedures.

Abstract: Se describen técnicas para soportar funciones de control de política y cobro (PCC) en una red de comunicación inalámbrica. En un diseño, una función de reglas de control de política y cobro (PCRF) puede recibir una solicitud de una primera entidad de red (por ejemplo, un agente local) para establecer una sesión de PCC para un equipo de usuario (UE) que accede a la primera entidad de red utilizando un protocolo de movilidad (por ejemplo, IP móvil). La PCRF puede determinar el protocolo de movilidad utilizado por el UE basándose en el parámetro del Tipo IP-CAN incluido en la solicitud. La PCRF puede determinar las reglas de PCC para sesión de PCC basándose en el protocolo de movilidad y puede enviar las reglas de PCC a la primera entidad de red. La primera entidad de red puede aplicar las reglas de PCC en los paquetes para la sesión de PCC y puede contar cada paquete para cobro. Una segunda entidad de red puede reenviar los paquetes pero no puede contar estos paquetes para cobro.

Abstract: Methods and apparatus for storing, manipulating, retrieving, and forwarding state, e.g., context and other information, used to support communications sessions with one or more end nodes, e.g., mobile devices, are described. Various features are directed to a mobile node controlling the transfer of state from a first access node to a second access node during a handoff operation thereby eliminating any need for state transfer messages to be transmitted between the second access node and the first access node during handoff. Other features of the invention are directed to the use of a core network node to store state information. State information stored in the core node can be accessed and used by access nodes in cases where a mobile node does not send a state transfer message during a handoff, e.g., because communication with the first access node is lost or because such messages are not supported.

Abstract: Se describen sistemas y metodologías que facilitan la transferencia de inter-sistema en un sistema de comunicaciones inalámbricas. Se describen en la presente diversos aspectos que proporcionan técnicas de transferencia que habilitan un sistema objetivo a ser preparado por un dispositivo móvil mediante un sistema fuente con objeto de minimizar los cambios específicos requeridos al sistema fuente y/o sistema objetivo. Se describen en la presente técnicas en las cuales puede utilizarse el enlace de radio de un sistema fuente para tunelizar mensajes de señalización los cuales se encuentran en un formato comprendido por un nodo destino en un sistema objetivo. Además, la transferencia rápida de inter-acceso puede facilitarse al establecer un simple túnel de transmisión genérica entre los nodos de red respectivos en los sistemas fuente y objetivo que manejan la movilidad intra-sistema y proporcionar un mecanismo de tunelización de Capa 2 (L2 - Layer 2) por la interfaz de radio de cada tecnología de sistema implementada.

Abstract: Methods and apparatus for compressing messages used to support mobile communications are described. After transmission of a first mobile IP message which may be a conventional mobile IP message, a compressed mobile IP message is transmitted. The compressed message includes a new "compressed message" indicator and information which is to replace information in the previous message or to be added to the previous message to construct a new message. In some embodiments, the compressed message includes a mask field, e.g., a sequence of bits, each bit corresponding to one field of a standard registration request message or binding update message. If the mask flag bit corresponding to a field is set, it indicates that the compressed message includes information to replace the content in the corresponding field of the previous message or to be added to the previous message as a field corresponding to the asserted bit.

Abstract: The claimed subject matter relates to performing routing in a wireless communications system. In more detail, each device associated with a wireless packet-switched network may not be aware of an identity and/or address of a particular point of attachment with respect to a wireless terminal. A data packet that should be provided to a particular point of attachment can be initially directed to a wireless terminal or a one-hop multicast address, for instance. Thereafter, the data packet can be encapsulated in a frame format and identity of the particular point of attachment can be provided in such frame. The frame can thereafter be routed to the point of attachment.
