PURPOSE:To minimize a power supply ON period in a battery saving period of a slave station as required in the system adopting multi-frame structure. CONSTITUTION:A master station 1 generates a specific number signal Sb representing a specific number of each slave station by using a specific number generating circuit 11 and a multiplexer circuit 12 is used to send the signal while being superimposed on a BS time slot of each frame to a slave station 2. A specific number synchronization circuit 25 generates a synchronizing signal Ss in subordinate synchronization with a BS period of the master station. A control circuit 27 calculates a timing based on a specific number of its own station stored by a storage circuit 26 and on the synchronizing signal Ss and generates a control signal Sc for applying on/off control of a power supply system. |
