Mobile station and method for providing ultra power-saving mode in mobile station

Abstract

Provided are a mobile station and a method for providing an ultra power-saving mode in a mobile station. The method for providing an ultra power-saving mode in a mobile station includes: inactivating a communication function in a standby mode of the mobile station; extracting a DRX (discontinuous reception) cycle length coefficient K of the mobile station; determining a class-specific DRX cycle length coefficient Ni of the mobile station; replacing K with Ni; and monitoring a paging signal at a paging cycle corresponding to Ni.

1 . A method for providing an ultra power-saving mode in a mobile station, comprising the steps of:
 transmitting a paging signal to the mobile station;   waiting for a paging response signal for a predetermined time;   determining a class-specific DRX cycle length coefficient N i  of the mobile station when the paging response signal is not received within the predetermined time; and   paging at a paging cycle corresponding to N i .   
     
     
         2 . The method of  claim 1 , wherein the paging signal transmitted periodically corresponding to N i  comprises text message information and incoming call record information.
