DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, the present invention will be explained with reference to the drawings. FIG. 1 is a block diagram of a paging system showing one embodiment of the present invention. In the paging system shown in FIG. 1, a case is shown in which a call requester 1 accommodated in a subscriber line exchange 2 calls a target pager 13 by a wireless base station 19 via a wireless paging exchange 3. The radio paging exchange 3 includes an incoming trunk 4 that connects to the subscriber line exchange 2, a base station control section 5 that connects to the radio base station 19, and a calling number receiver 6 that receives the calling number dialed by the call requester 1. , an additional number receiver 7 for receiving an additional number, a calling number storage section 10 for storing the number received by the calling number receiver 6, and an additional number storage section 11 for storing the number received by the additional number receiver.
and a main storage device 9 having a subscriber data storage section for storing subscriber information of the pager 13, and a central control device 8. The pager 13 includes a general call information storage section 14 that stores general messages, a secret information storage section 15 that stores secret messages, an information display section 16 that displays information, and a data key 17 for entering a password. , and a control unit 18.

The operation will be explained below. When calling the pager 13, the call requester 1 first dials the station number that includes the wireless paging exchange 3, and then dials the calling number to finish, or continues by dialing an additional number (message). do. This call request arrives at the incoming trunk 4 of the wireless paging exchange 3 via the subscriber line exchange 2 in which the call requester 1 is accommodated. The call request is sent from the incoming trunk 4 to the calling number receiver 6
The calling number receiver 6 receives the calling number dialed by the call requester 1. The received calling number is confirmed by the central control device 8 and stored in the calling number storage section 10 included in the main storage device 9.

The central control unit 8 extracts subscriber data corresponding to the received call number from the subscriber data storage unit 12 included in the main storage device 9 and analyzes it. As a result of the analysis, if the subscriber data corresponding to the calling number is a pager for receiving an additional number, the central control unit 8 connects the incoming trunk 4 and the additional number receiver 7. The call requester 1 dials an additional number and the additional number receiver 7 receives this additional number. The received additional number is confirmed by the central control device 8 and stored in the additional number storage section 11 included in the main storage device 9.

When the call requester 1 dials to indicate the end of the additional number, the central controller 8 stores the main memory 9
If an additional number (message) is retrieved from the additional number storage unit 11 included in the additional number and a special number indicating secret information is added to the additional number, a signal indicating that the information is secret is sent to the radio paging signal that calls the pager 13. , and sends this radio paging signal to the base station control unit 5.

The pager 13 receives the radio paging signal sent from the radio base station 19, detects the secret code added to the received radio paging signal by the control section 18, and stores the secret information storage section 1 included in the pager 13.
5 to store the call information. Note that if the secret code is not detected, the message is stored in the general call information storage section 14.

Next, the procedure for extracting the secret information received by the pager 13 will be explained using FIG. The pager 13 that has received the secret information displays a symbol indicating that the secret information has been received on the information display section 16 of the pager 13 to notify the pager owner that the secret information has been received (step 1, hereinafter S1). The pager owner enters a password to retrieve the secret information from the pager 13 using the data key 17 of the pager 13 (
S2). The control unit 18 of the pager 13 checks whether the input password matches a pre-registered password (S3), and if they match,
The secret information is displayed on the information display section 16 in the pager 13 (S4). After displaying the secret information for a certain period of time on the information display section 16 of the pager 13, the information displayed on the information display section 16 of the pager 13 is cleared (S5). Furthermore, if the verification results of the passwords input using the data key 17 of the pager 13 do not match, nothing is displayed on the information display section 16 of the pager 13.

In this embodiment, an example is shown in which the pager 13 is provided with two types of memory sections: general and secret, but by further increasing the number of memory sections corresponding to secret, the pager 13 can be used for various purposes.

[0013]

[Effects of the Invention] As explained above, in the present invention, the call requester inputs a special number indicating secret information, the wireless call exchange identifies this, and the secret information is stored separately from general information. This information is stored in the storage means for storing secret information in the pager, and is configured so that it cannot be displayed on the pager unless a password is entered from the pager to retrieve this information. The third
This has the effect of preventing secret information from being leaked to other parties.
