When a destination communication station receives a communication frame which contains a destination address matching an address of the destination communication station and whose assignment address description area contains unused assignment addresses, the destination communication station extracts one of the unused assignment addresses, generates the communication frame whose assignment address description area has been updated by extracting the assignment address, updates the address stored in an address storage area with the extracted assignment address to set up an assignment of the address of the station, and sends the generated communication frame to the next communication station so that the communication frame circulates among a plurality of communication stations.
