The exchange 2 is a subscriber telephone 1A,
It has a function of connecting 1B to the central base station 3. The central base station 3 and the peripheral base stations 4 form a call signal from the identification number of the target radio call terminal and the call message at the request of the caller, or carry the call signal at the request of the holder of the radio call terminal. A calling signal is formed from the identification number of the wireless calling terminal device and the unique password, and the calling signal is wirelessly transmitted to the wireless calling terminal device.

As shown in FIG. 2, the radio calling terminal device 10 is connected to a receiving section 12 via an antenna 11. The receiving unit 12 demodulates and decodes the received calling signal and outputs it to the reception control unit 13. The reception control unit 13 outputs a required control signal based on the calling signal, and controls the memory 14, the display 15, and the buzzer 16 as a notification means connected to the reception control unit by this control signal.

The memory 14 includes a ROM 14a and a RAM.
14b, and the ROM 14a stores its own unique identification number and password. Also,
The RAM 14b can store the message included in the call signal received by the control signal from the reception control unit 13.
The message stored in the RAM 14b can be read by a control signal from the reception controller 13. The display 15 can display that a call has been made and a message can be displayed by a control signal from the reception controller 13. The buzzer 16 is the reception controller 13
It sounds by the control signal from and notifies that there is a call. Incidentally, instead of or in addition to this buzzer, means for giving notification by blinking light such as a light emitting diode,
Alternatively, a means such as a vibrator may be provided to give a notification by vibration.

Further, the reception control unit 13 stores the identification number included in the calling signal received by the reception unit in the RO of the memory 14.
Compared with its own identification number stored in M14a, when both match, it is recognized that it is the own call,
A control signal is output to the buzzer 16 to ring it to perform a call notification operation, and at the same time, a control signal is output to the display 15 to display a call notification.

When the calling signal includes a message, the message is stored in the RAM 14b. Furthermore, when the calling signal includes a password, this password is compared with the own password stored in the ROM 14a, and when both match, RA
The message stored in M14b is read out and displayed on the display 15.

The operation when the caller calls a specific radio calling terminal device using the radio calling terminal device having the above configuration will be described with reference to FIG. The sender is a subscriber's telephone at hand, for example, the subscriber's telephone 1A through the exchange 2 to the central base station 3
And the identification number of the wireless calling terminal device 10 to be called and a calling message (usually a message number) are dialed. The central base station 3 forms a call signal based on the identification number and the call message number and transmits it. At the same time, it is also transmitted from the peripheral base station 4.

When the receiving unit 12 of the radio calling terminal device 10 receives the calling signal (step S101), it demodulates and decodes the calling signal and outputs it to the reception control unit 13. The reception control unit 13 recognizes the identification number included in the calling signal,
When this is compared with the own identification number stored in the ROM 14a, and when the two coincide with each other and it is recognized that the ringing signal is addressed to itself, a control signal is output to the buzzer 16 to ring the ringing signal. At the same time, the display 15 indicates that there is a call (step S102). When the reception control unit 13 recognizes that the calling signal includes the calling message (step S103), it stores the message in the RAM 14b of the memory (step S104). In this case, this message is not displayed on the display 15 and the standby state is maintained (step S1).
05).

The owner of the radio calling terminal device 10 makes the buzzer 1
When it is confirmed that there is a call by ringing 6 or a call display on the display 15, a subscriber telephone, for example, the subscriber telephone 1B, calls the central base station 3 through the exchange 2 to confirm the content of the message, and possesses it. The unique identification number and password of the wireless calling terminal device 10 being dialed are dialed. The central base station 3 forms a calling signal from the identification number and the password and transmits it. At the same time, it is also transmitted from the peripheral base station 4.

The radio calling terminal device 10 receives it.
When it is received (step S101), the demodulated and decoded signals are output to the reception control unit 13, and the reception control unit 13 recognizes that it is a call to itself as before, and then sounds the buzzer 16 and displays it. The call is displayed on 15 (step S102). Furthermore, the reception controller 1
In step 3, when it is recognized that the call signal includes the password (step S103), the RAM 14 of the memory 14 is detected.
A control signal for reading the stored information is output to b, the calling message stored in the RAM 14b is read (step S106), and the content is displayed on the display 15 (step S107). This allows
The owner displays the previously sent message on the display 15
It becomes possible to confirm in.

Therefore, the content of the message can be confirmed only by the person who knows the identification number and the password of the wireless calling terminal device possessed, and when the wireless calling terminal device is not in the possession of the owner, a message is attached. Even if a call is made, the message cannot be seen by others, and the confidentiality of the message can be secured. On the other hand, after a call is made, the owner can use the subscriber telephone to request a call to his or her own terminal device, so that the call message can be confirmed at any time.

Here, in the above-described embodiment, in order for the owner to confirm the message, it is necessary for the subscriber to re-call the telephone each time, but for example, the radio call terminal device is provided with a selection switch. The message may be unconditionally displayed when the calling signal is received by switching the selection switch. With this configuration, when the owner of the radio call terminal device is at hand, the message can be immediately confirmed when the call signal is received. Note that it is necessary to use a code number switch or the like because a simple selection switch allows another person to operate the switch to see the message.

As described above, according to the present invention, the message included in the received call signal is stored in the storage means without being displayed on the display unit, and the password unique to the received call signal is included. When the terminal is equipped with a means for displaying the message stored in the storage means on the display unit, the message cannot be viewed by simply receiving the call, and then the password is used to call again. You can see the message only when you do. Therefore, even if a call is made when the terminal device is not in the possession of the owner, another person cannot see the message and the confidentiality of the message can be secured. In addition, the owner can check the message at any time after calling.

Further, the present invention has a function of storing a password unique to itself in the storage means, and compares the password included in the received calling signal with the password stored in the storage means, and the two match. By displaying the message stored in the storage means on the display means at this time, the terminal device can perform the collation of the unique password and display the message.

Further, by simultaneously displaying the message stored in the storage means on the display means and performing the notification operation in the notification means, the holder knows the message display by the terminal device by the operation of the notification means, Confirmation can be surely performed.

By selecting the selection, a message can be written in the storage means and displayed on the display means at the same time as the notification operation for notifying the user's calling, and the message can be confirmed at the same time as the calling. It is also possible to do so.
