APPARATUS AND METHOD FOR OPERATION OF SLEEP MODE AND IDLE MODE IN MOBILE COMMUNICATION TERMINAL

摘要

An operating apparatus and a method thereof varying a transmission time to an idle mode from a sleep mode and flexibly used according to the use circumstance are provided to minimize power consumption and secure the mobility of the terminal. A normal mode operation is performed(202). The traffic is not generated for the predetermined time. A variable boundary value toward the operation of sleep/idle mode is calculated. The terminal measures the average CINR(Carrier to Interference Noise Ratio) value of the serving base station(205). The measured current average CINR value and boundary line value calculated are compared(206). The terminal implements the sleep mode operation(207). The terminal implements the idle mode operation(211).
