METHOD FOR OPERATING SLEEP MODE FOR EFFICIENT ENERGY MANAGEMENT OF MOBILE SUBSCRIBE STATION

摘要

A method for operating a sleep mode for efficient energy management of a mobile terminal is provided to reduce repetition of a sleep interval and a listening interval from a time after the mobile terminal is converted into a sleep mode in a sleep mode algorithm of IEEE 802.16e to a time when data to be received is generated. A method for operating a sleep mode for efficient energy management of a mobile terminal comprises the following steps. A sleep interval value is checked when terminating a sleep mode of the mobile terminal. The amount of data packet stored in a buffer of a base station is checked. The base station sets the minimum sleep interval to be used in the next sleep mode of the mobile terminal based on sleep interval information when a previous sleep mode is terminated.
