However, the above-mentioned conventional radio telephone apparatus has a problem that the mode switching between the cellular telephone and the cordless telephone must be manually performed.

An object of the present invention is to solve the above problems and to provide a radiotelephone device capable of automatically switching the modes of a cellular telephone and a cordless telephone.

[0009]

In order to achieve the above object, the present invention provides a conventional radiotelephone device with a speed measuring radio section for transmitting / receiving and modulating / demodulating a speed measuring radio wave, and the speed measuring radio section. A speed detection unit that detects the speed of the wireless telephone device based on the speed measurement radio waves received and demodulated by
A measurement radio wave generation processing unit that generates a speed measurement signal by a signal from a control unit of a wireless telephone device, and an automatic switching unit that switches between a cellular phone and a cordless phone by a signal output from the speed detection unit are added. It is a thing.

[0010]

According to the present invention, the moving speed of the radiotelephone device is detected by the speed detecting section from the speed measuring radio wave and its reflected wave, and the cellular phone and the cordless phone are automatically switched by the automatic switching section according to the speed. Is something that can be done.

[0011]

DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 is a block diagram showing the configuration of a wireless telephone device according to an embodiment of the present invention. In FIG. 1, reference numeral 10 is a speed measurement radio unit that transmits and receives speed modulation radio waves and performs modulation and demodulation, and 11 is the speed of a wireless telephone device based on the speed measurement radio waves received and demodulated by the speed measurement radio unit 10. Is a speed detection unit for detecting the speed measurement signal, 12 is a measurement radio wave generation processing unit that generates a speed measurement signal by a signal from the control unit 5 of the wireless telephone device, and 13 is a signal output from the speed detection unit 11 so that It is an automatic switching unit that switches between cordless phones.

The same functional blocks as those of the radio telephone device shown in FIG. 2 are designated by the same reference numerals, and the description thereof will be omitted.

The operation of the radiotelephone device configured as described above will be described below.

At the time of making a call, first, a telephone number signal, a calling command signal S1 and the like are input from the keypad section 6 to the control section 5.
In response to this call command signal, the control unit 5 outputs a speed measurement generation command signal S2. The speed measurement generation command signal is input, and the measurement radio wave generation processing unit 12 outputs the speed measurement signal S3. This speed measurement signal S3 is input, modulated by the speed measurement radio section 10, and the speed measurement radio wave S4 is transmitted to the antenna 1
To send via.

A reflected wave S5 of the transmitted speed measurement radio wave
The signal is demodulated and received by the speed measurement radio unit 10 via the antenna 1, the speed is detected by the speed detection unit 11 from the reflected wave and the speed measurement radio wave, and the speed information signal S6 is output. The speed information signal S6 causes the automatic switching unit 13 to output a cordless telephone mode signal if the cordless telephone can provide service and a cellular telephone mode signal if the cordless telephone cannot provide service. The cordless telephone mode signal or the cellular telephone mode signal is input, and the control unit 5 thereafter operates in either mode.

Thereafter, the actual calling process is started by the control unit 5 by the telephone number signal, the calling command signal S1 and the like which have been previously inputted from the keypad unit 6, and the control of the entire telephone device is started. The data processing unit 4 inserts the control data of the transmission side output from the control unit 5 into a predetermined position in the transmission data, and extracts the control data from the reception data of the reception signal output from the wireless unit 2. .

The voice processing unit 3 inserts the transmission voice signal input from the microphone 9 into the transmission data at a predetermined position as the transmission voice data and receives the reception data of the reception signal output from the radio unit 2. The received audio data is extracted from the speaker 8 and is output from the speaker 8 as a received audio signal. At the time of transmission, the wireless unit 2 combines the transmission data of the output of the voice processing unit 3 and the transmission data of the output of the data processing unit 4 as one transmission data, modulates this as a transmission signal, and transmits the transmission signal via the antenna 1. Send.

Further, the radio section 2 receives the antenna 1 when receiving.
The received signal received via the signal is demodulated and the received data is output to the voice processing unit 3 and the data processing unit 4. The display unit 7 displays information such as the input from the keypad unit 6 and the received electric field strength.

Basically, it operates as a cellular phone when in standby, and when it receives a call, it operates as a cellular phone.

[0020]

As described above, the wireless telephone device of the present invention automatically transmits a speed measurement radio wave when a call is made, and detects the speed of the wireless telephone device by the reflected wave and the speed measurement radio wave. However, it is possible to provide a wireless telephone device capable of automatically switching between a cordless telephone and a cellular telephone depending on the speed.
