<P>PROBLEM TO BE SOLVED: To optimally set a period of receiving a beacon signal in a terminal in accordance with a kind of application and/or communication properties (such as a communication pattern and a communication status). <P>SOLUTION: In a wireless communication system 1, a terminal 30 is identified by a base station 10 in accordance with beacon signals transmitted periodically from the base station 10, and to the identified terminal 30, the presence or absence of data to be transmitted and a period until a transmission of a next beacon signal are notified by a beacon signal. A terminal-side wireless communication section 36 in the terminal 30 transmits, to the base station 10, a request for setting of a period between transmissions of beacon signals. A communication control section 15 in the base station 10 sets the period between transmissions of beacon signals in accordance with the setting request having been received from the terminal 30. With this arrangement, the terminal 30 can optimize its period between receptions of beacon signals, thereby turning OFF power supply to a communication circuit 40 from a power source section 43 until the timing for receiving a beacon signal. This allows the terminal to reduce its power consumption. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
