Abstract: A method and apparatus for dynamically adjusting a power control loop that attempts to maintain either the transmit power of a signal sent from a base station to a mobile station or the signal to noise ratio of a signal sent from the mobile station (300) to the base station (400) above a minimum threshold and below a maximum threshold. Location information that is representative of the distance and morphology between the mobile station (300) and the base station (400) and the velocity of the mobile station (300) are determined. The minimum and the maximum thresholds of the power control loop are then adjusted in accordance with the location and the mobility information such that the minimum and the maximum threshold vary as the distance and the morphology between the mobile station (300) and the base station (400) and the velocity of the mobile station (300) change.; In addition, the step size used to increase or decrease the transmit signal power, is adjusted in accordance with the velocity of the mobile station (300). A transmitter sends the signal at a power level that is controlled by the power control loop with the adjusted minimum threshold.

Abstract: A system and method for monitoring the load on a CDMA communication system having a base station and a plurality of users. A measure of voice activity in the communication system is determined, and a current value of frequency reuse efficiency equal to an initial value of frequency reuse efficiency is provided. A power determination is made according to the measured voice activity and the current value of frequency reuse efficiency. The current value of frequency reuse efficiency is updated using the power determination to provide a new current value of frequency reuse efficiency. The power determination and the update of the frequency reuse efficiency are iteratively repeated until convergence to provide a converged value of frequency reuse efficiency. The load on the communication system is then determined according to the converged frequency reuse efficiency value.

Abstract: A system and method for updating a current set of parameters in a communications system is provided. The system and method determines the current position of a mobile unit in a first coverage area, determines a set of optimum parameters based on the current position of the mobile unit, and updates the current set of parameters in the mobile unit with the set of optimum parameters. The system and method may be used for optimizing position-dependent system-access and soft-handoff parameters.
