INFORMATION PROCESSOR, COMMUNICATION SYSTEM, INFORMATION PROCESSING METHOD AND PROGRAM

摘要

PROBLEM TO BE SOLVED: To efficiently use radio communication resources.SOLUTION: The information processor includes: a communication part; and a control unit. The communication part transmits a device discovery request signal for performing a direct radio communication between devices. At the timing after transmitting the device discovery request signal, the control unit changes the detection threshold level for detecting a radio communication signal. When the control unit receives a device discovery request signal for performing a direct radio communication between the devices from another information processor, and when a piece of predetermined information is included, the control unit transmits a device discovery response signal to the other information processor based on the predetermined information included in the device discovery request signal.SELECTED DRAWING: Figure 2
