In this paging service, a subscriber carries a small carrier signal receiving device specified by a unique identification number and acts. When paging is performed, a paging transmitted from a base station is performed. A carrier signal for transmitting information is received by a carrier signal receiver carried by the subscriber. The operation to be performed by the person who wants to page the subscriber can be performed, for example, by dialing a unique identification number of the carrier signal receiver carried by the subscriber using a telephone connected to a public telephone line.

A carrier signal for transmitting such paging information is, for example, a digital frequency modulation based on paging information in the form of coded binary data with respect to a carrier signal having a predetermined frequency of 280 MHz. (For example, F with a frequency deviation of ± 2.5 kHz

The carrier signal receiving apparatus that receives the paging-dedicated carrier signal performs demodulation processing on the received paging-dedicated carrier signal to obtain paging information demodulation output, and further performs decoding processing on the paging information demodulation output to reproduce paging information. When information is obtained and the identification number represented by the identification data included in the reproduction paging information matches its own identification number, a paging operation such as paging display and vibration generation according to the reproduction paging information is performed.
