Abstract: A novel method and apparatus is disclosed for performing seamless handoff of a mobile station (MS) between Radio Access Networks (RANs) that use different types of wireless interfaces. The described embodiments enable an MS to handoff between different RANs without causing routing ambiguity, and without substantial loss of network data. Upon moving from the coverage area of a first RAN using a first wireless interface to the coverage area of a second RAN using a second wireless interface, an MS determines whether routing ambiguity may result from the change of RAN and, based on the determination, triggers a re-registration of its network address. A foreign agent (FA) within a packet data serving node (PDSN) monitors network address re-registrations in order to determine whether multiple RAN-PDSN (R-P) connections are being created for the same MS. Based on this determination, the PDSN terminates redundant R-P network connections resulting from movement of the MS between different RANs.

Abstract: A method and a wireless communication device capable of flow controlling data to be sent from a TE2 device over a Rm interface when PPP renegotiation occurs over a Um interface. Flow control is asserted by the MT2 device by means of manipulating electrical signaling of a physical interface between the MT2 device and the TE2 device. A second embodiment provides a method and a wireless communication device for buffering data on the MT2 device when the PPP renegotiation of the Um interface occurs. In a third embodiment, data is buffered when the PPP renegotiation of the Um interface occurs. When an amount of free buffer space is less that a predetermined threshold, flow control is asserted to the TE2 device.

Abstract: La presente invencion describe un metodo y aparato para dar servicio de eventos especificados utilizando una aplicacion de estacion movil en un sistema de comunicacion inalambrica. La presente invencion incluye una interfaz de programa de aplicacion (API) se facilita las comunicaciones entre una pila de protocolo de comunicacion de estacion movil, la cual se comunica con una red de comunicaciones, y una aplicacion de estacion movil. La aplicacion de estacion movil determina los eventos especificados a los que se dara servicio y deshabilita la notificacion subsiguiente de los eventos especificados a los que se dio servicio.

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: An improved method and system for terminating dormant mode wireless packet data sessions when a remote network node becomes inaccessible. A wireless subscriber station sends the wireless network a termination notification identifying a packet data session corresponding to a remote network node that has become inaccessible and should be terminated.

Abstract: A method for selectively maintaining compression state and applying a compression technique after a PPP renegotiation on a Um interface of a wireless communicaiton network. A communication device (104) receives packetized data transmitted from a terminal device (102), which is coupled t o the communication device via an Rm interface. The communciaiton device determines (S315) whether the received packetized data comprises compressed or uncompressed data. Upon determining that the received packetized data comprises compressed data, the communicaiton device determines (S340) whethe r connection information exceeds a highest-numbered decompression slot from a plurality of decompression slots on said Um interface. The communciation device sets up (S330) a local decompression slot, int he communicaiton devic e, which corresponds to the connection information in order to maintain said compressionsate, wherein the local decompression slot is set up in response to determining (S325) that the connection information exceeds the highest- numbered decompression slot. The communication device decompresses (S350) th e compressed packetized data when it receives compressed packetized data containing said connection information.
