Abstract:
A radio communication system comprising at least one radio communication apparatus, and a radio control apparatus, connected to the radio communication apparatus via radio waves, for performing communication using a frequency hopping method, said radio control apparatus comprising:frequency determination means for determining frequencies to be used in frequency hopping communication;hopping-pattern configuring means for configuring a hopping pattern based on the frequencies determined by said frequency determination means;notification means for notifying said radio communication apparatus of the hopping pattern configured by said hopping-pattern configuring means;instruction means for instructing an end of intermittent reception to said radio communication apparatus; andfirst control means for performing control such that, when said frequency determination means has redetermined frequencies while said radio communication apparatus performs the intermittent reception, said instruction means instructs the end of the intermittent reception, said hopping-pattern configuring means reconfigures the hopping pattern, and said notification means notifies the reconfigured hopping pattern;said radio communication apparatus comprising:intermittent reception means for performing intermittent reception based on the hopping pattern notified from said notification means; andsecond control means for performing control such that, when the instruction of the end of the intermittent reception from said instruction means has been received, the intermittent reception is ended, and said radio communication apparatus shifts to a state of receiving the notification of the hopping pattern from said notification means.
