    Abstract: A method and apparatus of determining signal strength, regardless of the signal data rate, in a receiver receiving signals from a variable rate transmitter. The incoming signal is comprised of a series of frames. Each frame is comprised of a number of power control groups containing data. The number of the power control groups containing data within each frame is dependent on the unknown data rate. The position of the power control groups within the frame is a pseudorandom. The signal strength of an incoming signal of unknown data rate is determined based upon an active set of power control groups within a frame. The active set of power control groups contain data independently of the unknown data rate. The signal strength information may be used to indicate that the signal strength is sufficient to perform further signal processing.

    Abstract: En sistema movil de comunicaciones inalarnbricas, un subsistema de estacion base (20) incluye por lo menos un transceptor (32), el cual se comunica por una interfase aerea con una pluralidad de estaciones moviles (22, 24) que operan de acuerdo con una pluralidad de estandares de protocolo diferentes. Las estaciones moviles incluyen por lo menos una primera estacion movil (22) que opera de acuerdo con un primer estandar de protocolo (IS-95) y por lo menos una segunda estacion movil (24) que opera de acuerdo con un segundo estandar de protocolo (GSM) . El subsistema de la estacion base (20) incluye un administrador de localizador/acceso (36), el cual, enruta por medio de una red (26, 28, 30) que actua en respuesta al protocolo, cada una de las llamadas entre el subsistema de la estacion base (20) y una de las estaciones moviles (22, 24).
