Abstract

PURPOSE: To transmit a voice signal and data simply and efficiently by sending the data for a period when no voice signal is sent. CONSTITUTION: In the case of the simultaneous communication mode of voice and data set by a key board 13, a control section 11 gives an instruction of checking it that a data terminal equipment is connected to a data terminal equipment connection section 2 to a communication IF section 3. The communication IF section 3 checks the connection and informs it to the control section 11 when the connection is made. Upon the receipt of the notice, the control section 11 gives an instruction of changeover control of a digital data changeover device 7 to a voice/silence detection section 6. The detection section 6 sequentially calculates power of voice from voice data received from a voice processing section 5 and discriminates it to be silence when the voice level is below a predetermined voice level and throws the changeover device 7 to the position of the communication IF section 3 and throws the changeover device 7 to the position of a voice processing section 5 when the level is over the voice level. Thus, the digital data changeover device 7 selects data from the communication IF section 3 or the voice processing section 5 and the selected data are fed to a MODEM section 8.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a telephone for data communication other than voice.

[0002]

2. Description of the Related Art Conventionally, when performing data communication with a telephone,
The data of the data terminal was input to the voice input / output terminal of the telephone via the communication modem.

[0003]

However, the above-mentioned conventional example has a problem that voice communication cannot be performed while data communication is being performed.

[0004]

According to the present invention, a connection unit for connecting a data terminal, a detection unit for detecting the presence / absence of voice, and a detection unit for detecting the silence of voice are provided. Data communication is performed, and voice communication is performed when the presence of voice is detected.

[0005]

The present invention will be described in detail below.

FIG. 1 is a block diagram of a digital cordless telephone which is an embodiment of the present invention.

In FIG. 1, reference numeral 1 is an externally connected data terminal for data communication, 2 is a data terminal connection section, 3 is a communication terminal for communication with the data terminal, and a communication interface for inputting / outputting digital data to / from a modulation / demodulation section 8. A phase unit, 4 is a voice transmitter / receiver, 5 is a voice processing unit that performs compression encoding processing and decompression decoding processing of voice data, and 6 is a voice processing unit that outputs voice data in real time based on the voice data from the voice processing unit 5. A sound / sound detection unit that detects whether the sound level is a sound level or a sound level and sends the detection result to the digital data switching unit 7. The digital data switching unit 7 switches between the communication interface unit 3 and the voice processing unit 5. , 8 is a modulator / demodulator for modulating digital data and demodulating received data, and 9 is an RF for transmitting / receiving.
Reference numeral 10 is an antenna for transmitting and receiving radio waves, 11 is a control unit for controlling each unit, 12 is a digital cordless telephone main body, and 13 is a keyboard.

FIG. 2 is a flow chart for explaining the operation of the digital cordless telephone embodying the present invention.

Next, the operation of the telephone will be described with reference to FIG.

The digital telephone can be set to three modes of voice communication, data communication, and simultaneous communication of voice and data by inputting from the keyboard 13.

If the simultaneous voice and data communication mode is set (ST1), the control section 11 issues an instruction to the communication interface section 3 to check whether or not the data terminal is connected to the data terminal connection section 2 ( ST2).

The communication interface section 3 checks whether or not the data terminal is connected, and if so, notifies the control section 11 that the data terminal is connected.

When the control unit 11 receives this notification (ST
3), the digital data switching unit 7 in the sound / silence detection unit 6
It is instructed to perform the switching control of (ST5).

The sound / silence detection section 6 sequentially calculates the power of the sound from the sound data from the sound processing section 5 (ST6),
When the sound level is lower than a predetermined sound level, the digital data switching unit 7 is considered to be silent and is switched to the communication interface unit 3 side (ST7).

When the voice level is reached, the digital data switch 7 is switched to the voice processing section 5 side (ST8).

As described above, by the digital data switch 7, the communication interface 3 or the voice processing unit 5 is provided.
Data is switched and the data is sent to the modulator / demodulator 8 (ST9).

The modulation / demodulation unit 8 modulates the received data, sends it to the RF unit 9, and sends a radio wave to the wireless line via the antenna 10 (ST10).

In this way, by transmitting data when there is no voice, one voice line can simultaneously perform voice and data communication.

As described above, in the present embodiment, in order to transmit voice and data communication easily and efficiently, when the sound / silence detection section 6 detects silence, the switch 7 is switched to the communication IF section 3. By connecting the modulation / demodulation unit 8 and detecting a voice, the voice processing unit 5 and the modulation / demodulation unit 8 are connected to perform data communication by the data terminal 1 when there is no sound and voice communication by the handset 4 when there is sound.

In the above embodiment, the data terminal connection unit 2 and the communication interface unit 3 are provided inside the digital cordless telephone, but they are provided inside the external adapter and the charging stand for the telephone so that they are connected to the digital wireless telephone. You may make it connect.

The present invention is not limited to digital cordless telephones, but can be applied to analog cordless telephones and digital or analog wired telephones.

[0022]

As described above, since the data communication is performed when the voice is silent, the voice and the data communication can be transmitted easily and efficiently, which is a very excellent effect.
