METHOD AND APPARATUS FOR REDUCING POWER OF A CDMA MOBILE STATION BY CONTROLLED TRANSITION FROM CONTROL HOLD TO ACTIVE STATE

摘要

A method and apparatus for reducing power dissipation in mobile stations that are configured to provide concurrent voice and high-speed packet data communication capability in a cellular telecommunications system. A state is defined during which data directed to a mobile station (MS) is not received but the MS. Such a reduced receive processing state may be co-extensive with a Control Hold state. A need to process received signals, particularly on high bit-rate data channels, may be reduced by permitting receive processing to be suspended for signals that are not directed to a particular mobile station. A notification mechanism is presented by which a serving base station directs a mobile station to return from reduced to full receive processing in advance of transmitting data on a packet data channel. The notification may take several forms, such as a message presenting the MS MAC address and one or more bits of predetermined data content.
