Abstract: In a communication system in which a gateway entity (32) is linked to a plurality of infrastructure entities which in turn are operable to communicate with an access terminal (44), the access terminal needs first to establish a data attachment point (DAP) with one of the infrastructure entities (34). Handoff of the DAP from one infrastructure entity (34) to another infrastructure entity (36) is initiated by the access terminal (44). The access terminal weighs factors such as the link conditions with the various infrastructure entities, the time since the last DAP handoff, and time duration communicating with the current infrastructure entity before proceeding with the DAP handoff.

Abstract: A method and apparatus are disclosed for negotiating and managing one or more personalities in a wireless communications system. The method comprises advertising one or more supported initial protocol set identifiers. Furthermore, the method comprises selecting a starting initial protocol set identifier from the advertised initial protocol set identifiers. In addition, the method comprises establishing a session based on the selected starting initial protocol set identifier. The method also comprises establishing a connection between an access terminal and an access network based on the selected initial protocol set identifier.

Abstract: Systems and methods for switching among heterogeneous networks and inter-working between a source access system and a target access system. An inter-system handoff control component can facilitate setting an IP tunneling by the mobile unit, wherein IP addresses for inter-working security gateway and Radio Access Network of the target access system can be identified. The inter-system handoff control component can then implement tunneling between the source system and the target system, wherein signaling/packeting associated with the target system can be transferred over the source system.

Abstract: Dependiendo de las condiciones del canal, se puede ajustar un cronómetro para abortar variables con relación a la comunicación inalámbrica de paquetes de datos. Adicionalmente, el tamaño del tampón disponible se puede evaluar y utilizar para ajustar una duración de tiempo del cronómetro para abortar variables. Cuando se envía una secuencia de paquete, se pueden perder los paquetes. Cuando se reorganiza un paquete perdido, el cronómetro se puede iniciar y se puede enviar una solicitud para la retransmisión del paquete perdido. Si el paquete perdido no llega durante la ejecución del cronómetro para abortar variables, entonces la secuencia del paquete se puede procesar sin el paquete faltante.

Abstract: En un sistema de comunicación en el cual una entidad (32) de puerto de enlace se enlaza a una pluralidad de entidades de infraestructura las cuales a su vez operan para comunicarse con una terminal (44) de acceso, la terminal de acceso necesita establecer primero un punto de unión de datos (DAP) con una de las entidades (34) de infraestructura. La transferencia de la DAP desde una entidad (34) de infraestructura a otra entidad (36) de infraestructura se inicia por la terminal (44) de acceso. La terminal de acceso pondera los factores tales como las condiciones de enlace con las diversas entidades de infraestructura, el tiempo desde la última transferencia de DAP y la duración del tiempo en comunicarse con la entidad de infraestructura actual antes de proceder con la transferencia de DAP.

Abstract: A novel group key distribution and management scheme for broadcast message security is provided that allows an access terminal to send a single copy of a broadcast message encrypted with a group key. Access nodes that are members of an active set of access nodes for the access terminal may decrypt and understand the message. The group key is generated and distributed by the access terminal to the access nodes in its active set using temporary unicast keys to secure the group key during distribution. A new group key is provided every time an access node is removed from the active set of access nodes for the access terminal.

Abstract: A route protocol is established whereby a mobile device can communicate to a multitude of (receiving) base stations though a tunnel created through a serving base station. A message that includes a Route Creation Header can be transmitted by the mobile device to create the tunnel. The Route Creation Header is reviewed by the receiving base station while the mobile device is in a Waiting-To-Open State. Various errors might occur with respect to the Route Creation Header. These errors can be conveyed to the mobile device by base station by setting one or more error code fields. Once the errors are resolved, another attempt to create a tunnel with base station can be made, if desired.
