Abstract: Systems and techniques are disclosed relating to wireless communications. The systems and techniques involve monitoring a first network in accordance with a first air interface, and receiving a message from a second network through the first air interface, the second network being associated with a second air interface different from the first air interface. Various registration and related techniques are also discussed for maintaining connectivity with both networks as the wireless communications device moves through different geographic coverage regions.

Abstract: Micro-tunnels are used to provide multiple data service sessions to the same mobile node in a wireless communications system. Further, the flexibility of the micro-tunnels optimizes the resources of the system. On request for a data service, an encapsulation configuration record is generated. An encapsulation header is created in response to the encapsulation configuration. The encapsulation header includes a packet service identifier and a micro-tunnel identifier.

Abstract: Techniques for minimizing call setup latency are disclosed. In one aspect, multiple signaling messages are encapsulated and sent as a single message thus reducing the total delay incurred by sequential transmission. In one embodiment, an encapsulation message includes a field indicating the number of messages encapsulated therein. In one example, the encapsulation is performed at a Link Access Control (LAC) layer. Alternate embodiments may perform encapsulation at an alternate layer.

Abstract: A method and apparatus for requesting PPP instances from a packet data services network includes a mobile station configured to send an origination message to a packet data service node (PDSN) at which it has arrived upon leaving the vicinity of another PDSN. The message informs the new PDSN of the new location of the mobile station and indicates both the number of dormant PPP instances associated with the mobile station and a service reference identifier for each such PPP instance. A flag within the message may be used to indicate whether the PPP instances are dormant (i.e., whether the mobile station is engaged in a call). Communications channel resources of packet data services nodes are optimized by reducing the information included in messages from the Packet Control Function network element to the Packet Data Service Node network element, and by reducing the use of Mobile Internet Protocol agent advertisement.

Abstract: Method and apparatus for variable length Physical Layer (PL) packet generation. Multiple Security Layer (SL) packets may be multiplexed into a single PL packet to increase efficiency, wherein the SL packets may have variable lengths. In one embodiment, different format SL packets for different users are combined into capsules that form the PL packet. Shorter packets are for users in poor channel conditions or requiring smaller amounts of data due to the applications and the accompanying Quality of Service (QoS) requirements. In one embodiment, a modified Preamble structure provides for Unicast or multi-user packets. Alternate embodiment provides modified Rate Sets, a mechanism for identifying ACK from a single-user packet or a multiplexed packet (delayed ACK). ON/OFF keying for ACK channel v/s bi-polar keying used in IS-856, and/or multi-valued interpretation of DRC.

Abstract: Methods and apparatus for providing location information to an Access Terminal (AT) when the Access Network (AN) is unable to contact a last serving PDSN, else maintaining the previous location information. In one embodiment, AN elements within an area supported by a Packet Data Serving Node (PDSN) are given a same Access Network ID (ANID). In this way, movement of the AT within the area supported by the PDSN do not initiate an update of location information. The AT receives location information specific to the PDSN and not the AN.

Abstract: Un metodo y aparato novedoso se describe para realizar transferencia sin union de una estacion movil (MS) entre Redes de Acceso de Radio (las RAN) que utilizan diferentes tipos de interfaces inalambricas. Las modalidades descritas permiten que una MS transfiera entre diferentes RAN sin provocar ambigüedad de ruta, y sin perdida sustancial de los datos de red. Por el movimiento del area de cobertura de una primera RAN utilizando una primera interfaz inalambrica al area de cobertura de una segunda RAN utilizando una segunda interfaz inalambrica, una MS determina si la ambigüedad de ruta puede resultar del cambio de RAN y, basandose en la determinacion, dispara un re-registro de su direccion de red. Un agente extranjero (SA) dentro de un nodo de servicio de datos de paquete (PDSN) monitorea los re- registros de direccion de red que estan siendo creados por la misma MS. Basandose en esta determinacion, el PDSN termina las conexiones de red de R-P redundantes que resultan del movimiento de la MS entre las diferentes RAN.

Abstract: Method and apparatus for secure transmissions. Each user is provided a registration key. A long-time updated broadcast key is encrypted using the registration key and provided periodically to a user. A short-time updated k ey is encrypted using the broadcast key and provided periodically to a user. Broadcasts are then encrypted using the short-time key, wherein the user decrypts the broadcast message using the short-time key. One embodiment provides link layer content encryption. Another embodiment provides end-to-e nd encryption.
