Abstract:
A communication system including a plurality of communication devices communicating by a frequency hopping method, comprising:communication means for deciding on a first frequency hopping pattern used in a communication from among a plurality of frequency hopping patterns and for communicating by using the decided on first frequency hopping pattern; detection means for, in a course of communication between first and second communication devices by using the first frequency hopping pattern, detecting predetermined control information representing that a third communication device requests to communicate with the first communication device; and control means for controlling so as to interrupt the communication between the first and second communication devices in response to the detection made by said detection means and to start a communication between the first and third communication devices, wherein said communication means communicates, in a case where the communication between the first and third communication devices is started, by using the frequency hopping pattern used in the communication between the first and second communication devices.
