    Abstract: A method and apparatus for generating an autonomous Pilot Strength Measurement Message (PSMM) by a mobile station traveling in a multi-carrier wireless communication system. In a multi-carrier system, the mobile station receives the pilot channel of a base station on multiple carrier frequencies simultaneously. Fading may vary from carrier frequency to carrier frequency. New pilot strength definitions are used by the mobile station in a set of rules transmitted by the base station. The set of rules determines autonomous generation and transmission of PSMMs by the mobile station upon detection of pilots.

    Abstract: Un metodo para detectar cuadros de datos retardados en una funcion de transporte incluye los pasos de comparar un contador de la secuencia de cuadros con un valor umbral predeterminado (304), detectar un cuadro retardado si el contador de la secuencia excede el valor umbral, y procesar el cuadro retardado y detectado en consecuencia (306). En un protocolo de transporte de datos RLP, el cuadro retardado puede ser procesado como un cuadro retransmitido. El valor umbral puede ser proporcional al numero maximo de cuadros enviados en un conjunto dado de ese retraso maximo, en unidades de intervalos de cuadro, entre cuadros enviados simultaneamente sobre el aire en el mismo intervalo de cuadros.

    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: In a channel structure for use in communication systems, two sets of physical channels, one for the forward link (50) and another for the reverse link (52), are utilized to facilitate communication of a variety of logical channels. The physical channels comprise data and control channels. In the exemplary embodiment, the data channels comprise fundamental channels which are used to transmit voice traffic, data traffic, high speed data, and other overhead information and supplemental channels which are used to transmit high speed data. The fundamental channels can be released when the remote stations are idle to more fully utilize the available capacity. The control channels are used to transmit paging and control messages and scheduling information.
