PROBLEM TO BE SOLVED: To reduce the power consumption in the standby state and to improve the utilizing efficiency of a control channel by providing plural intermittent reception modes with a different period to the mobile communication equipment and informing the setting mode to the mobile communication network. SOLUTION: Mobile communication equipments PS1, PS2,... of this system are provided with 1st and 2nd intermittent reception modes with a different reception period as an intermittent reception mode in the standby state. The 1st mode is a mode receiving a control channel sent from base stations BS1, BS2,... at a comparatively short period not causing a program such as connection delay and the 2nd mode is a mode with a long period to be set for a time zone with a low traffic. When either of the two modes is designated, the mobile communication equipments PS1, PS2,... start the reception by this intermittent reception mode and inform the intermittent reception mode to a control station CS. The control station CS sets a transmission timing of the control channel to a different timing in response to the informed intermittent reception mode.
