发明名称 METHOD AND APPARATUS FOR OPERATING A RADIOTELEPHONE IN AN EXTENDED STAND-BY MODE OF OPERATION FOR CONSERVING BATTERY POWER
摘要 This invention provides a method, and apparatus for performing the method, for reducing the power consumption of a radiotelephone. The method includes the steps of (a) receiving with a receiver of a radiotelephone at least a Word Synchronization pattern from a frame that is transmitted over a control channel; (b) receiving a first repeat of a control message that follows the Word Synchronization pattern within the frame; and (c) determining if the first repeat was correctly received. If the first repeat was correctly received, the method includes a further step of (d) determining if at least one reception-related criteria is met. If the reception-related criteria is determined to be met, the method includes a further step of (e) selectively removing operating power from one or more portions of the radiotelephone receiver for a predetermined time period during a remainder of the frame. The at least one reception-related criteria is a Message Error Rate (MER) that indicates a number of correctly received frames out of a total number of n last received frames. The reception-related criteria may also include a difference between a minimum Received Signal Strength Indicator (RSSI) value and a maximum RSSI value that are detected during a predetermined interval of time.
