Abstract

PROBLEM TO BE SOLVED: To attain changing without the input operation of a call opposite party number by automatically changing-over the number to be transmitted from a key-inputted number into the number received from a mobile station radio wave equipment in a selection call radio wave equipment where the opposite station number is transmitted as data before voice. SOLUTION: The number inputted from the key input part 2 is inputted to a transmission buffer 6 through a change-over circuit 4 and transmitted before voice. In the meantime, at the time of reception, reception is executed by an antenna 9, a reception signal 18 demodulated by a receiving part 7 is inputted to a reception buffer 5. Data 16 from the reception buffer 5 is displayed by a display part 1 and simultaneously inputted to the transmission buffer 6 through the change-over circuit 1l. Therefore, in next transmission, the number is not the key-inputted one but the one received latest so that a call opposite party is automatically changed-over to the mobile station of the number received latest and the number input is not required.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement of a calling method using data of a radio device.

[0002]

2. Description of the Related Art In the case where a command station radio and a plurality of mobile station radios are used to make a call individually between the command station radio and a specific mobile station radio, the conventional technique is as follows. , Is as follows. At the time of transmission, the mobile station radio transmits the number of its own radio as data prior to the voice, and when receiving, outputs the received voice to the speaker when the received data matches the number of its own radio. It works.
The command station radio always outputs the received voice to the speaker, and displays the received data, that is, the mobile station number on the display unit. At the time of transmission, the number input from the key input unit is transmitted prior to the voice. Therefore, when the command station radio individually talks to a specific mobile station, it is necessary to enter the number of that mobile station radio, and when there is a reception from another mobile station radio and you want to talk to that radio. You also need to enter that number.

FIG. 2 is a block diagram of the command station radio of the above-mentioned Celecole radio, and its operation will be described in detail below. For the operation at the time of reception, receive from the antenna 28,
The reception unit 26 demodulates into a reception signal 36 in the voice band. One of the reception signals 36 is input to the reception buffer 24, and the other is output to the speaker 30 via the switch 32. Received data 33 output from the receive buffer 24
Is input to the control unit 23 and displayed on the display unit 21.
Here, when the reception data 33 is input, the switch 32 is turned on by the control signal A38 from the control unit 23,
The reception signal 36 is output to the speaker 30 and reproduced.
As for the operation at the time of transmission, the number data input by the key input unit 22 is input to the control unit 23 and is input to the transmission buffer 25 as the transmission data 34. At the same time, the control unit 23 controls the changeover switch 31 by the control signal B37, sets the changeover switch 31 to the data side while outputting the transmission data 34, and otherwise sets the changeover switch 31 to the microphone 29 side. Set to. The transmission data 34 or the microphone voice 35 is modulated by the transmission unit 27 and the antenna 2 is transmitted.
Sent from 8. Therefore, the received number data is finally displayed on the display unit 21, and when transmitting, the number data input from the key input unit 22 is transmitted.

[0004]

In the above-mentioned prior art,
Disadvantage that when you are in an individual call with a mobile station, you receive a call from another mobile station and you have to enter the number of that mobile station when you want to make an individual call with that mobile station, that is, when you want to change the other party There is. An object of the present invention is to eliminate these drawbacks and to provide a radio device with good operability.

[0005]

In order to achieve the above-mentioned object, the present invention transmits voice before voice. When the number data is keyed in, the number is transmitted, and when it is received from the mobile station radio, it is automatically changed to the received number and transmitted.

[0006]

As a result, when the key-in number is transmitted, the mobile station of that number is called and the call starts, so the number data transmitted from the mobile station is the same as the key-in number and continues. You can talk. When receiving from another mobile station, the number data to be transmitted will be switched to the number of that mobile station, so there is no need to key in the number again, and you can talk directly to another mobile station. be able to.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIG. The operation at the time of reception is to receive from the antenna 9 and demodulate to the reception signal 18 in the voice band by the receiving unit 7. One of the reception signals 18 is input to the reception buffer 5 and the other is input to the switch 1
It is output to the speaker 11 via 3. The reception data 16 output from the reception buffer 5 is input to the control unit 3 and displayed on the display unit 1, and at the same time, input to the transmission buffer 6 via the switching circuit 4. Received data 1 here
When 6 is received, the switch 13 is turned on by the control signal B20 from the control unit 3, and the reception signal 18 is output to the speaker 11 and reproduced.

In the operation during transmission, when there is no key input from the key input unit 2, the data input to the transmission buffer 6, that is, the number received from the mobile station is used as it is.
When there is a key input from the key input unit 2, the number is output as the transmission data 15 from the control unit 3, and at the same time, the switching circuit 4 operates by the switching signal 14 and the transmission data 1 is transmitted.
5 is input to the transmission buffer 6. While transmitting the number data, the changeover switch 12 is set to the transmission buffer 6 side by the control signal A19, and thereafter, the changeover switch 12 is switched to the microphone sound 17 side from the microphone 10. Changeover switch 1
Transmission data switched by 2 or microphone voice 1
The signal 7 is modulated by the transmitter 8 and transmitted from the antenna 9.

In summary of the above operation, the number data to be transmitted at the time of transmission is the input number when there is a key input, and the received number when it is received from the mobile station. It works.

[0010]

As described above, according to the present invention, in the select call radio for making an individual call, it is usually necessary to input the number of the mobile station of the other party with whom the call is to be made, but there is reception from the mobile station. In that case, since the number is automatically switched, the operation of inputting the number becomes unnecessary, and a SELECALL radio device with good operability can be realized.

Claims (1)

[Claims] 1. A command station radio and a plurality of mobile station radios are provided, number data is transmitted prior to voice at the time of transmission, and upon reception, the number data is received by a speaker according to the contents of the received number data. In the Cerecor radio that determines whether to output audio, the mobile station radio transmits the number of its own radio before transmitting the voice when transmitting, and the received data is the number of the local radio when receiving. If it is, it operates to output the received voice to the speaker, and the command station radio
The received voice is always output to the speaker, and when transmitting, the latest received number of the partner station radio is transmitted as data before the voice, and the command station radio and mobile station radio make individual calls. In this case, select call that eliminates the need to input the number when the call partner changes by automatically switching the number data of the partner station radio transmitted from the command station radio to the latest received radio number. transceiver.
