    Abstract: A method and apparatus are provided for coordinating times at which a mobile station (5) monitors alternative frequencies with times at which an origination base station (10) transmits short messages. The origination base station (10) determines when the mobile station (5) can be tuned to frequencies other than an origination frequency and transmits a signal commanding the mobile station to tune to an alternative frequency at a particular time. The mobile station (5) first receives commands from the origination base station (10). The commands indicate when the mobile station (5) can be tuned to receive frequencies other than an origination frequency. Based on the commands, the mobile station (5) can select time periods during which it will be tuned to frequencies other than the origination frequency. Short messages are transmitted from the origination base station (10) only at times when the mobile station (5) is known to be tuned to receive the origination frequency based on the knowledge of when the mobile station will be tuned to frequencies other than the origination frequency. A window may be created during which the mobile station (5) can cease receiving information over the origination frequency without any reduction in a total amount of data.

    Abstract: Un sistema de comunicaciones móviles, que comprende: una primera estación base (4) para transmitir y recibir (20, 26), respectivamente, una señal de enlace directo y una señal de enlace inverso procedente de una estación móvil (8), y para generar (24) un primer mensaje de potencia de transmisión para determinar un nivel de potencia de transmisión de dicha señal de enlace directo; una segunda estación base (6) para transmitir (32) una versión redundante de dicha señal de enlace directo a dicha estación móvil (8) y para recibir (38) dicha señal de enlace inverso procedente de dicha estación móvil, y para generar (36) un segundo mensaje de potencia de transmisión para determinar el nivel de potencia de transmisión de dicha versión redundante de dicha señal de enlace directo; un controlador centralizado (2) para recibir (10) dichos mensajes primero y segundo de potencia de transmisión, y para enviar (12, 14, 16) una instrucción de control de potencia alineada a dicha primera estación base y a dicha segunda estación base, en el que dicha primera estación base y dicha segunda estación base están en comunicación simultáneamente con dicha estación móvil, en el que dicha instrucción de control de potencia alineada es para producir patrones alineados de ajustes de control de potencia en dichas estaciones base primera y segunda para transmisiones de dicha señal de enlace directo procedente de dicha primera estación base y dicha versión redundante de dicho enlace directo desde dicha segunda estación base hasta dicha estación móvil, y en el que el controlador centralizado solo envía la instrucción de control de potencia alineada si los niveles de potencia indicados por los mensajes primero y segundo de potencia de transmisión divergen en más de un umbral de divergencia.

    Abstract: A method and apparatus for coordinating the time at which a mobile station (5) performs searches for alternative systems to which a hard handoff will occur. In one system which includes the present invention, the mobile station (5) receives a command which instructs the mobile station (5) as to when to tune to alternative frequencies in order to search for indications of the presence of an alternative system. In another system which includes the present invention, predetermined times are defined with respect to a reference point in time that is common to both an origination base station (10) and a mobile station (5). The mobile station (5) tunes to alternative frequencies to perform searches only during these predetermined times. In addition, the mobile station (5) coordinates the transmission of reports which indicate the results of searches for alternative systems such that these reports are only transmitted from the mobile station (5) when the mobile station (5) is tuned to the origination frequency.

    Abstract: A system and method for generating random numbers in a wireless communication network is presented. The noise present in the signal received by a wireless receiver is extracted to form random numbers. Wireless transmitters typically are identified by a synchronization signal. In acquiring the synchronization signal, a wireless receiver generates a plurality of psuedorandom sequences, despreads an incoming signal, integrates the resulting signal, and performs an energy computation to calculate an energy measure. One or more energy measures are collected in a pool of bits, and the bits are hashed to extract random numbers.
