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,
In particular, it relates to cellular cordless telephone exchanges.

[0002]

2. Description of the Related Art In recent years, portable telephones such as cellular telephones that can be used in the car or outdoors and cordless telephones that use radio instead of the cord between the telephone body and the handset have been used. Came.

A conventional cellular telephone as described above will be described below with reference to the drawings.

FIG. 2 is a block diagram showing the structure of a conventional cellular telephone. In the figure, 1 is a mobile telephone radio unit for transmitting and receiving radio signals as a mobile telephone, and 2 is a signal processing unit for processing signals. 3 is a voice processing unit for processing a voice signal, 4 is a control unit for controlling the whole, 5 is a speaker unit for outputting voice, 6 is a microphone unit for inputting voice, 7 is a display unit for displaying, and 8 is It is an operation unit for inputting an operation signal.

In the conventional cellular phone as described above, an incoming call input through the mobile phone radio section 1 is detected by the signal processing section 2 and notified to the control section 4 to connect the line. The input voice signal is transmitted to the speaker unit 5 through the voice processing unit 3, and the voice is input from the microphone unit 6 and transmitted to the outside through the mobile telephone wireless unit 1 through the voice processing unit 3.

When making a call, the signal processing unit 2 connects to a cellular line via the mobile phone radio unit 1 based on a signal input from the operation unit 8 and performs voice processing similar to that of an incoming call. .

While such processing is being carried out, the control section 4 controls each section and informs the necessary information to the outside on the display section 7.

[0008]

However, the above-mentioned conventional cellular telephone has the following problems.

The cost of using a cellular telephone line is higher than that of a public line. For example, when a group consisting of a plurality of members communicates by using a cellular telephone outdoors, it is necessary for each of them to make a line contract and purchase a cellular telephone. It is necessary, and the line usage cost is high and uneconomical.

The present invention solves the above-mentioned problems, and prepares a plurality of cordless telephones (slave handsets) which are relatively low in cost and easy to obtain. If it is possible to make a call to the target line via the wireless line of the device and send / receive messages, and some of these handsets want to use the cellular line, use the cellular telephone communication function of this device to make a call. The purpose of the present invention is to provide a cellular cordless telephone exchange that enables effective use of telephone lines.

[0011]

In order to achieve the above object, the present invention provides a cellular telephone having one or a plurality of radio units for mobile telephones and a cordless telephone (slave unit).
It has a configuration including a plurality of cordless telephone wireless units that communicate with each other, and a circuit switching unit that connects and exchanges voice signals with the mobile telephone wireless unit and the cordless telephone wireless unit.

[0012]

According to the present invention, when a plurality of cordless telephones are within the cordless communication range, the cordless telephones can communicate with the outside by using the cellular telephone line, and the cordless telephones use the line. With or without, it works to communicate without going through a cellular telephone line.

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

In FIG. 1, 1 is a mobile phone radio unit for transmitting and receiving radio signals as a mobile phone, 2 is a signal processing unit for processing signals, 3 is a voice processing unit for processing voice signals, and 4 is a whole. A control unit for controlling a voice, a speaker unit for outputting a voice, a microphone unit for inputting a voice, a display unit for displaying 7, an operation unit for inputting an operation signal, a reference numeral 9 for a cellular telephone line, a cordless telephone A line switching unit for exchanging lines and voice signals of this unit, 10 is a cordless telephone (slave unit)
It is a wireless unit for a cordless telephone that transmits and receives a wireless signal to and from.

With respect to the cellular cordless telephone exchange having the above components, the mutual relationship between the components and the operation thereof will be described below.

An incoming call from the cellular telephone line is detected by the signal processing unit 2 via the mobile telephone radio unit 1 and is then controlled by the control unit 4.
Then, the line switching unit 9 is switched depending on whether the connection is made to the voice processing unit 3 of the unit or the cordless telephone wireless unit 10 is connected to the external cordless telephone slave unit.

An incoming call from the cordless handset is detected by the signal processing unit 2 via the cordless telephone radio unit 10 and notified to the control unit 4 to be connected to the voice processing unit 3 of the unit or to the cordless telephone radio unit. Connect to another cordless handset via the unit 10, or
The circuit switching unit 9 is switched by determining whether to connect to the cellular phone line via the mobile phone radio unit 1.

A call from this unit is detected by the signal processing unit 2, is notified to the control unit 4, and the wireless unit 10 for the cordless telephone.
Or connect to an external device via the
The circuit switching unit 9 is switched by determining whether to connect to the cellular telephone line via the.

As described above, according to this embodiment, this unit or any cordless telephone can use the cellular telephone line through communication with this unit, and this unit can be used regardless of whether or not the cellular telephone line is used. It is possible to communicate with another child device or this device through communication with.

[0020]

As is apparent from the above embodiments, according to the present invention, the exchange of the cellular telephone and the cordless telephone,
Since communication becomes possible, the cellular phone line can be effectively used from multiple cordless phones, the number of lines that can be used apparently increases, and even while using the cellular phone line (without using the cellular phone line), the cordless phone (Handset) Since calls can be made between each other, it is possible to provide a cellular / cordless telephone exchange that can significantly reduce the cost of using a cellular telephone line.
