    Abstract: La descripcion se enfoca en un dispositivo de comunicacion movil que mide caracteristicas o atributos de una primera red de comunicaciones que varia de acuerdo con la ubicacion fisica dentro de esa primera red de comunicaciones para crear una impresion digital, o firma, de una ubicacion dentro de la primera red de comunicaciones; cuando se crea la impresion digital de la ubicacion actual del dispositivo movil, esta se puede comparar con una impresion digital conocida asociada con una segunda red de comunicacion para determinar la proximidad del dispositivo movil a la segunda red de comunicaciones; por ejemplo, la primera red de comunicaciones puede ser una red de comunicacion inalambrica de area amplia CDMA y la segunda red de comunicaciones puede ser una LAN inalambrica 802.11.

    Abstract: Métodos y aparatos que facilitan la atenuacion de una condicion de nudo oculto en una red inalámbrica de malla, en los que los nodos utilizan un protocolo de requerimiento para enviar (RTS, resquet to set) / listo para enviar (CTS, clear to send) en conjuncion con un protocolo de requerimiento asíncrono híbrido automático de repeticion. Por ejemplo, un nodo puede competir por un conjunto de subportadores mediante el envío de una senal de RTS sobre los subportadores deseados, y puede recibir una senal de CTS sobre los subportadores, por los cuales se compite, indicando la senal de CTS sobre cuáles subportadores el nodo puede transmitir datos. Si otro nodo ha ganado la competencia por un subportador en particular, el nodo que hace el requerimiento puede ajustar un nivel de potencia con el cual transmite un RTS o un paquete de datos a efectos de que el nodo que efectua el requerimiento utilice el subportador sin interferir con el nodo ganador.

    Abstract: A METHOD OF USING A CIPHERING KEY IN A MOBILE STATION (40) FROM A FIRST BASE STATION (12) IN A FIRST CELLULAR COMMUNICATIONS SYSTEM CONTROLLED BY A FIRST MOBILE SWITCHING CONTROL STATION TO A SECOND BASE STATION (14) IN A SECOND, DIFFERENT CELLULAR SYSTEM CONTROLLED BY A SECOND MOBILE SWITCHING CONTROL STATION IS DESCRIBED.THE METHOD COMPRISES GENERATING FOR THE MOBILE STATION (40) A CIPHER KEY FOR USE BY THE MOBILE STATION (40) DURING COMMUNICATION IN THE SECOND CELLULAR COMMUNICATIONS SYSTEM.THE CIPHER KEY IS GENERATED BY THE MOBILE STATION (40) FROM A PRIVATE KEY ASSIGNED TO THE MOBILE STATION (40) FOR THE SECOND CELLULAR COMMUNICATIONS SYSTEM AND FROM A RANDOM NUMBER GENERATED BY THE SECOND CELLULAR COMMUNICATIONS SYSTEM. THE CIPHER KEY IS THEN COMMUNICATED TO THE FIRST MOBILE SYSTEM AND A PRIVATE LONG CODE IS GENERATED FOR USE BY THE MOBILE STATION (40) DURING COMMUNICATION IN THE FIRST CELLULAR COMMUNICATIONS SYSTEM.(FIG 4)

    Abstract: Systems and methods are described that facilitate performing interference management techniques between sending and receiving nodes in order to provide minimum transmission rate guarantees. Carrier-to-interference ratio (C/I) may be controlled by employing specialized resource utilization messages (RUMs), the number and rate of which may be governed by a "token bucket" mechanism. For instance, a maximum token bucket size may be defined for a node, which describes the maximum amount of data that may pass through the node at a given time. A current number of tokens in the node's bucket may be evaluated and compared to a threshold value, and RUMs may be transmitted by the node as long as the current token number is greater than the predefined threshold value. Tokens may additionally be deducted from the node's bucket for successful data transmissions, thus providing a dynamic interference control mechanism.

    Abstract: The disclosed embodiments provide for methods and systems for monitoring a paging channel. In one aspect, a method for monitoring a paging channel includes monitoring a paging channel for a page message at scheduled paging slots, determining that an error has occurred at a given paging slot, and monitoring the paging channel for a re-page message at least one scheduled re-paging slot, where the re-paging slots occur after the given paging slot but before the next scheduled paging slot. In another aspect, a method for monitoring a paging channel includes monitoring a first one of a plurality of paging channels for a page message at scheduled paging slots, determining that an error has occurred at a given paging slot, and monitoring at least a second one of the plurality of paging channels for the page message.
