Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wireless telephone device.

[0002]

2. Description of the Related Art FIGS. 2 and 3 are block diagrams of a conventional radiotelephone device, in which 1 is a display unit, 2 is an operation unit, 3 is a receiving unit, and 4 is a receiving unit.
Is a transmitter, 5 is an antenna, 6 is a cordless wireless unit for wireless communication for cordless phones, 7 is a cellular wireless unit for wireless communication with a wireless telephone service network such as a cellular phone, and 10 is continuous with a cordless base unit. ID regularly or regularly
Detecting unit for exchanging cords and detecting that it is within the radio wave coverage of the cordless telephone, 8 is a control for supplying power to the above-mentioned units and for making a display request to the display unit 1 according to the detection result of the detecting unit 9. Reference numeral 9 denotes an apparatus main body including the blocks.

The operation of the wireless telephone device configured as described above will be described below with reference to FIGS.

In the case of the conventional example 1 shown in FIG. 2, when the cordless base unit does not exchange the ID code with the cordless telephone in the standby state and the user of the radio telephone device makes a call operation, the cordless radio unit 6 , If a call request signal is transmitted to the cordless master unit via the antenna 5 and a call response signal from the cordless master unit is received within a predetermined time,
Subsequent call processing is performed, and the user of the wireless telephone device finds that it is within the radio wave arrival range. On the other hand, if the call response signal from the cordless base unit cannot be received within the predetermined time, the call processing is stopped, and the cordless telephone cannot make a call. It can be seen that it is out of the radio range.

In the case of the conventional example 2 of FIG. 3, in the standby state of the cordless telephone, the detector 10 continuously or periodically exchanges the ID code with the cordless base unit, and outputs the exchange result to the controller 8. The control unit 8 makes a display request to the display unit 1 according to the replacement result. As a result, the user of the wireless telephone device can determine whether or not it is within the radio wave coverage of the cordless telephone before making a call operation.

[0006]

However, in the above-described wireless telephone device of the first conventional example, it is not possible to determine whether or not it is within the usable range of the cordless telephone unless the calling operation is performed, and the second conventional example. In the wireless telephone device, the ID code is continuously or periodically exchanged with the cordless base unit, so that there is a problem that the power consumption is large.

The present invention has solved the above-mentioned problems and has a display unit, a detection unit for outputting an ID code request signal to a base unit of a cordless telephone, and a detection unit for detecting reception of an ID code from the base unit of the cordless telephone, and a cellular telephone. To a cordless telephone, when the user of the wireless telephone device performs an operation of switching, an ID code request signal is transmitted to the detection unit, and a display request is issued to the display unit according to the ID code reception detection result from the detection unit. By providing a control unit, the user of the wireless telephone device can be instructed whether or not it is within the radio wave coverage of the cordless telephone before the call operation by the cordless telephone and with low power consumption. It is an object of the present invention to provide a wireless telephone device that enables

[0008]

In order to achieve the above object, the present invention outputs an ID code request signal to a display unit and a base unit of a cordless telephone, and further detects the reception of an ID code from the base unit of the cordless telephone. When the user of the radiotelephone device performs a switching operation from the cellular phone to the cordless phone, the detection unit is caused to transmit an ID code request signal, and an ID code reception detection result from the detection unit According to the above, a control unit for making a display request to the display unit is provided.

[0009]

According to the present invention, with the above-described structure, the user of the wireless telephone device can be instructed whether or not it is within the radio wave arrival range of the cordless telephone before the calling operation is performed by the cordless telephone and the power consumption is reduced. It is possible to do in.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a block diagram of the present embodiment, and the display unit 11, the operation unit 12, the receiving unit 13, the transmitting unit 14, the antenna 15, the cordless radio unit 16, and the cellular radio unit 17 are the same as those in the prior art. , 18 is ID to the base unit of cordless telephone
A detection unit 19 which outputs a code request signal and further detects the reception of an ID code from the cordless telephone base unit, 19 supplies power to the above respective units, and performs switching operation from the cellular telephone to the cordless telephone by the user of the wireless telephone device. When the ID code request signal is transmitted to the detection unit 18, the display unit 1 is operated according to the ID code reception detection result from the detection unit 18.
A control unit 20 for making a display request to the display unit 20 is an apparatus main body including the above blocks.

The operation of the wireless telephone device configured as described above will be described below with reference to FIG.

When the user of the radio telephone device switches the radio telephone device from the cellular telephone to the cordless telephone by a predetermined operation, the control unit 19 causes the detection unit 18 to transmit an ID code request signal, and the detection unit 18 is activated. Wait for the ID code from the cordless base unit. Next, when the detection unit 18 receives the ID code from the cordless base unit within a predetermined time, it outputs a detection success signal to the control unit 19,
The control unit 19 determines that it is within the radio wave arrival range of the cordless telephone, and causes the display unit 1 to display that fact. On the other hand, if the detection unit 18 cannot receive the ID code from the cordless base unit within a predetermined time, it outputs a detection failure signal to the control unit 19, and the control unit 19 is out of the radio wave coverage of the cordless telephone. It is determined and the display section 11 is made to display that fact.

[0014]

As described above, according to the present invention, the instruction of whether or not the wireless telephone device is within the radio wave coverage of the cordless telephone is given to the user of the wireless telephone device before the calling operation is performed by the cordless telephone. A wireless telephone device that can perform power consumption can be provided.
