Description

[Detailed description of the invention] [Purpose of the invention] (Industrial application field) The present invention relates to a radio telephone apparatus with a call function having a selective call function.

(Prior Art) Conventionally, in a wireless telephone device such as an MCA (multi-channel access) system or a business radio, transmission and reception cannot be performed simultaneously, and a communication is performed by alternately transmitting and receiving.

By the way, in such a wireless telephone device, a call from a calling station is waiting in a receiving state, so that if there is a call from the calling station, the answering station will unilaterally output sound.

For this reason, in situations where it is not desirable to hear the voice around, the power of the wireless telephone device is turned off or the volume is reduced to a minimum so that the voice is not output even when there is a call. .

However, when such measures are taken, there is a disadvantage that the owner cannot know that the call has been made and cannot contact him.

(Problems to be Solved by the Invention) As described above, in order to prevent sounds from being heard in the surroundings by the conventional wireless telephone device with a calling function, the power of the wireless telephone device is turned off or the volume is minimized. There is no other way but to narrow down, and in such a state, there is a problem that it is difficult to know that there is a call.

The present invention has been made to deal with such a point, and provides a wireless telephone device with a calling function that can be used as a so-called pager in a situation where it is not desired to hear a voice around.

[Structure of the invention] (Means for solving the problem) According to the invention, a call signal including destination information designating a partner station and information on a call station is transmitted, and a response to the call signal is returned. In a wireless telephone device with a call function that allows communication between the two speakers to be set, receiving means for receiving the call signal and the call voice,
Input means for designating a call mode for suppressing output of a call voice received by the receiving means, and extracting means for extracting information relating to a calling station and destination information from a call signal received by the receiving means And when the calling signal is addressed to the own station and the calling mode is designated by the input means, a suppressing means for suppressing the output of the call voice after the communication setting, and the output of the call voice by the suppressing means. And a notifying means for notifying the incoming call from the calling station to the own station based on the information on the calling station extracted by the extracting means when the call is suppressed.

(Operation) In the present invention, when the call mode is specified, the output of the received voice is suppressed, so that the received voice is not output even if there is a call. At this time, information relating to the calling station is extracted from the selective calling signal and stored in the storage means. Further, the stored information is displayed by the display means.

Since the wireless telephone device with a calling function can be used as a pager in this manner, even if there is a call, there is no need to listen to the surrounding voice, and the calling station can be confirmed by the information stored in the storage means.

In addition, if information indicating the call mode is written in the response signal, the calling station can also know that the responding station is in the call mode.

(Example) Hereinafter, an example of the present invention is described using a drawing.

Also, the transmission sound input from microphone 250 is amplified by transmission sound amplifier 260 and transmitted to transmitter 170 via transmission sound mute 270.

The CPU 310 performs overall control of the entire wireless telephone device 10.
Further, the CPU 310 is capable of transmitting transmission data to the transmitter 170 via the modem 330 and inputting reception data from the receiver 150. Transmitter 17 from CPU310
When sending transmission data to 0, the transmission data and microphone 2
To prevent mixing with the transmitted voice input from 50,
The CPU 310 operates the transmission audio mute 270. Further, when receiving data is input from the receiver 150, the CPU 310 operates the receiving audio mute 210 in order to prevent the received data from being input to the receiving audio amplifier 230 and being output from the speaker 240.

The keyboard 350 includes numeric keys and function keys, and the pressed key is recognized by the CPU 310.

The display 370 is, for example, a liquid crystal display capable of displaying several digits and various functions.

The switching between the transmission mode and the reception mode is performed by a press talk switch (not shown), and when the press talk switch is pressed, the transmission mode is set.

Next, a calling procedure of the wireless telephone device 10 configured as described above will be described.

As shown in FIG. 2, when the press talk switch of the wireless device 1 is first pressed, a call signal is transmitted from the wireless device 1. The call signal includes a call command, a partner station number, and a local station number as shown in FIG. 3 (a). The partner station number and the own station number are input by a predetermined operation of the keyboard 350 of the wireless device 1, and are stored in the memory 390.

The wireless device 2 that has received the calling signal checks the partner station number included in the calling signal, and if it matches the own station number (if the calling signal is addressed to the own station), sends a response signal to the wireless device 1. Send. The response signal is composed of a response command, a partner station number, a local station number, and a message as shown in FIG. 3 (b). The message is composed of, for example, a three-digit number.

Then, the speech sound is transmitted from the wireless device 1 that has received the response signal.

In a situation where a plurality of wireless telephone devices are used, the call signal is received by all the wireless telephone devices in the receiving state.
With the selective calling function for designating a partner station in the above-described call signal, a call can be made with a specific partner station.

Next, an operation when the wireless telephone device 10 is used in a call mode (pager mode) will be described.

FIG. 4 is a flowchart showing the operation in the pager mode.

Predetermined operation of keyboard 350, to pager mode,
For example, a shift is made by pressing “*” and “9”.

Next, it is checked whether or not a calling signal addressed to the own station is received, and a loop is performed until a calling signal addressed to the own station is received (step 402). In this case, as described above, the partner station number of the received call signal is checked, and whether or not this number is the same as the own station number is checked.

Then, when a calling signal addressed to the own station is received, a response signal including a message indicating the pager mode is transmitted to the called station (step 403).
In this method, the number of the calling station is extracted from the calling signal, and a response signal having this number as the partner station number is transmitted. The message indicating the pager mode includes, for example, a three-digit number previously determined with the partner station, for example, "999"
Is used.

Next, the number of the calling station is displayed on the display 370, and a notification sound is output from the speaker 240 for a predetermined time (step 404). The notification sound is generated by a timer in the CPU 310 and transmitted to the reception audio amplifier 230 via the reception audio mixer 220.

Further, the number of the calling station is stored in the memory 390 (step 405). The calling station number stored in the memory 390 is read out by a predetermined operation of the keyboard 350 and displayed on the display 370.

As described above, in the wireless telephone device 10 set to the pager mode, the received voice is muted by the received voice mute 210, so that the received voice is not output from the speaker 240.

Also, after the calling station number is stored in the memory 390,
The display 370 is read out by a predetermined operation of the keyboard 350.
Is displayed, so that the calling station can be confirmed and contacted later.

Further, since the response signal message transmitted to the calling station indicates that the own station is in the pager mode, the calling station can know that the partner station is in the pager mode.

Note that the response signal message is stored in the keyboard 350 in advance.
Are sent from the memory 390 and stored in a predetermined area of the memory 390. Therefore, when the pager mode is set, a message indicating that the pager mode is set is reset. Further, a message storage area may be separately provided in the pager mode and the normal mode, and a message according to the set mode may be transmitted. Further, a message indicating the pager mode may be written in the ROM.

[Effects of the Invention] As described above, according to the present invention, by switching the mode, the device functions as a so-called pager. In addition, it is possible to know that a call has been made by the notification sound, and it is possible to confirm the calling station based on the information stored in the storage means after the fact.
