  • Method and apparatus for transition of operation mode in a wireless communication system
    Publication number: 20060160558
    Abstract: A method is provided for reducing power consumption of a mobile station (MS) in a wireless communication system. If a period of time for state transition from a normal mode to a sleep mode or an idle mode expires, the MS transmits a request message for state transition to a corresponding operation mode to a base station (BS) with which the MS is currently communicating. Upon receiving a response message to the request message, the MS performs a state transition to the sleep mode or the idle mode. Upon detecting a change in service area in the sleep mode, the MS performs a state transition to the normal mode. Upon receiving a paging advertisement message from a corresponding BS in the idle mode, the MS performs a state transition to the normal mode.
