PURPOSE: To place a call in unit of prescribed group by using a specific message word as a secondary address code word. CONSTITUTION: An ID is collated by using the ID address of an address code word, and after it is confirmed that data is the one addressed to this receiver, the data included in the message area of the following message code word is recognized as an individual ID address. It can be judged that a message is the one addressed to this receiver by collating the individual ID address (S104, S105). When coincidence is obtained as a result of collation, it is judged that the data is the one addressed to this receiver (S106). Also, the ID address and the individual address included in the address area of the address code word are registered on this receiver in advance. Therefore, the ID address can be easily expanded as using a decided regulation such as a POCSAG system. Also, only specific customers can be called simultaneously. |
