1. A communication system comprising:
a search communication apparatus configured to communicate with another communication apparatus over a first channel; and a plurality of search subject communication apparatuses; the search communication apparatus comprising:
a switcher configured to switch a channel used for communication between the first channel and a second channel different from the first channel, wherein the switcher is configured to, during communication with the another communication apparatus over the first channel, switch to the second channel for a predetermined period of time and return to the first channel, anda search request transmitter configured to, once the switcher switches from the first channel to the second channel for the predetermined period of time, transmit a search request signal over the second channel, the search request signal including information about the first channel; and each of the search subject communication apparatuses comprising:
a search subject receiver configured to receive the search request signal over the second channel; anda search subject transmitter configured to transmit, to the search communication apparatus, a search response signal which is a response to the search request signal received by the search subject receiver, the search subject transmitter transmitting the search response signal over the first channel, based on the information about the first channel included in the search request signal; and wherein the predetermined period is a search period in which the search request transmitter can transmit the search request signal, the search request transmitter transmits information indicating the search period, the search subject receiver receives the information indicating the search period transmitted from the search communication apparatus, and based on the information indicating the search period, the search subject transmitter transmits the search response signal by using the second channel, in the search period, and transmits the search response signal by using the first channel, after the search period has elapsed.
