Abstract

A radio communication system for registering an ID code of a communication partner in a transceiver easily and surely. In a first step, a slave set transmits “pairing application data” including a slave set ID to a master set. In a second step, the master set transmits “pairing reception data” including a master set ID and the slave set ID to the slave set. In a third step, the slave set transmits “first pairing selection data” including the slave set ID and the master set ID to the master set. In a fourth step, the master set transmits “second pairing selection data” including the master set ID and the slave set ID to the slave set. After the master set and the slave set recognize that processing for selecting communication partners is performed between the master set and the slave set according to the first to the fourth steps, in a fifth step, the slave set registers the master set ID of the master set and transmits “pairing completion data” to the master set. In a sixth step, the master set, which has received the “pairing completion data”, registers the slave set ID of the slave set.

Claims

1. A radio communication system in which data communication is performed by radio between a first transceiver and a second transceiver, to which unique ID codes are allocated, and the first transceiver and the second transceiver register ID codes of communication partners, include own ID codes in data when transmitting data, and specify the communication partners from ID codes included in data when receiving the data, wherein

in order to mutually recognize and register ID codes between a pair of the first transceiver and the second transceiver in which ID codes of communication partners are not registered, the radio communication system executes pairing processing comprising:

a first step in which the first transceiver transmits pairing application data including an own ID code;

a second step in which the second transceiver, which has received the pairing application data, transmits pairing reception data including an own ID code and the ID code of the first transceiver acquired from the pairing application data;

a third step in which the first transceiver, which has received the pairing reception data, transmits first pairing selection data including the own ID code and the ID code of the second transceiver acquired from the pairing reception data;

a fourth step in which the second transceiver, which has received the first pairing selection data, transmits second pairing selection data including the own ID code;

a fifth step in which the first transceiver, which has received the second pairing selection data, registers the ID code of the second transceiver as an ID code of a communication partner and transmits pairing completion data including the own ID code; and

a sixth step in which the second transceiver, which has received the pairing completion data, registers the ID code of the first transceiver as an ID code of a communication partner.

2. The radio communication system according to claim 1, wherein the second transceiver performs data communication by radio between each of a plurality of the first transceivers and executes the pairing processing individually between each of the plural first transceivers, whereby the second transceiver registers ID codes of the respective first transceivers and the respective first transceivers register the ID code of the second transceiver.

3. The radio communication system according to claim 1, further comprising:

informing means; and

pairing end informing means for informing a user of end of the pairing processing using the informing means when the pairing processing ends.

4. The radio communication system according to claim 2, further comprising:

informing means; and

pairing end informing means for informing a user of end of the pairing processing using the informing means when the pairing processing ends.
