A wireless mobile telephone () is operated so as manage the performance of 'off-frequency searches,' that is, searches for base station pilot signals that differ in frequency from the pilot signals in the mobile station's active set. Whenever frequency searching is performed (such as responsive to emerging from a reduced-power sleep mode), the mobile station performs on-frequency pilot signal searching () upon a prescribed active set frequency. Only if a prescribed off-frequency searching condition (-) is satisfied, the mobile station additionally performs off-frequency pilot signal searching () upon one or more neighboring base stations' frequencies.

Method and apparatus to optimize off-frequency pilot searching by wireless mobile station

A mobile station ( ) may include a terminal equipment ( ), a mobile station modem ( ), a mobile telephone ( ), and other features. A CPU ( ) selectively generates control signals to efficiently control transmission of supplemental channel request messages (SCRM) by the mobile station ( ). In one embodiment, transmission of a SCRM in response to a predetermined event is prohibited until a fixed period of time has elapsed since the last transmission of an SCRM in response to the predetermined event.

System and method for sending a supplemental channel request message in a wireless communication device

Novel techniques are disclosed for adjusting a power control setpoint to compensate for imperfect signal detection in a communication channel capable of discontinuous transmission (DTX). The power control setpoint is compensated for false detections by adjusting the power control setpoint by a dynamically determined setpoint back off amount upon detection of a Good frame. The amount of the setpoint back off is a function of the measured signal quality of the detected Good frame and the number of Erasure indications received immediately preceding the Good frame indication.
