Cell phone calling system using wired and wireless telephones {Cellular Phone calling system using general telephone}

The present invention relates to a mobile phone calling system using a general wired / wireless telephone, and more particularly, to a system that enables a cheaper call than a normal rate by automatically making a call through a mobile phone when a long distance call is attempted by a general wired or wireless telephone. .

In addition, the present invention relates to an apparatus for displaying a call so that the caller can recognize a call made in a general wired or wireless telephone during a mobile phone call.

In recent years, the rapid increase in the penetration rate of mobile phones is now an indispensable necessity in daily life.

Anytime, anywhere, regardless of the place can make a phone call and the small size is very convenient to use mobile phones are characterized by a certain charge regardless of the region.

However, in the case of using a general wired or wireless telephone, there is a disadvantage that the charge is higher than that of the mobile phone because charges are differentially charged according to the distance used.

The present invention has been made in view of such a point, and an object of the present invention is to provide a mobile phone call system that can reduce the charge burden by allowing a call through a mobile phone automatically when a long distance call using a general wired or wireless telephone.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a conceptual diagram of the apparatus of the present invention.

As shown in Fig. 1, the cellular phone calling system 1 of the present invention also has a function as a charger and is provided with two telephone lines 2 and 3 and one cellular phone jack 4.

The telephone line includes a telephone line 2 connected to a general wired / wireless telephone 6 and a telephone line 3 connected to a telephone line outlet input from the outside.

The mobile phone connection jack 4 is configured to be connected to the mobile phone (5).

2 is a block diagram according to an embodiment of the present invention.

As shown in Fig. 2, the mobile phone calling system of the present invention comprises a telephone connection unit 11 for connecting a general wired or wireless telephone to the apparatus, and a telephone station line connection unit 10 for connecting a telephone station line that is input from a telephone station. The device is operated in connection with the general wired and wireless telephone 6 and the cellular phone 5.

The mobile phone calling system of the present invention also includes a DTMF receiver 12 which detects a dialing number when the user dials through a general wired / wireless telephone and inputs it to a central processing unit described later to perform a control operation of the central processing unit. The ring detector 13 detects an external call input from the telephone company when the call is made through the mobile phone and inputs it to the central processing unit so that the user can confirm that the call is received from the outside. CO line switch 14 is configured to connect to the desired device by selecting whether or not to talk to the mobile phone.

In addition, the mobile phone calling system of the present invention, in order to compensate for the fact that the normal telephone is supplied with the operating power from the telephone station, but when connecting the mobile phone to generate a voltage equal to the voltage supplied from the telephone station to operate the wired and wireless telephone stably (FFEDING BRIDGE) (15) and a speech network that separates a voice signal into a reception signal and a transmission signal in order to receive or transmit a voice signal from a general wired or wireless telephone, and transmits the voice signal from the mobile telephone to a general telephone ( SPEECH NETWORK 16, a communication unit 17 for converting a digital signal input and output from the central processing unit of the apparatus into a signal that can be recognized by the mobile phone, thereby facilitating data communication between the mobile phone and the central processing unit, Charge your mobile phone while determining whether it is connected to the unit By inputting the signal to the central processing unit, the mobile phone can be called by the user when the mobile phone is connected according to the judgment of the central processing unit. The charging detecting unit 18 is configured to allow.

The mobile phone calling system of the present invention also detects a dial signal by a general telephone as a central control device of the apparatus, allowing a call through a mobile phone or a general telephone line, and detecting a ring signal input to a general telephone when the mobile phone is called. The central processing unit that determines whether the mobile phone is connected to the device and recognizes it to the user, and enables the user to make a call through the general telephone through the data communication with the mobile phone (19) ), A charging unit 20 for charging the mobile phone, and a DC power supply unit 21 for supplying the operating power of the apparatus.

The central processing unit 19 has a program for comparing the call rate per call time and the call rate through a mobile phone for each region, and a program for determining based on distance, for example, it is advantageous to use a mobile phone when talking on which region. Is stored.

Referring to the operation of the present invention configured as described above are as follows.

First, an operating voltage is supplied from the DC power supply unit 21 to the system, and the central processing unit 19 processes signals input from the charge detecting unit 18 and a general wired / wireless telephone to determine a state of charge of a mobile phone. When the user presses the area code and the phone number of the other party to be called using a general wired or wireless telephone, the numeric signal is input to the central processing unit 19 through the receiver 12 to determine which area the call is for. do.

As a result of the determination of the central processing unit 19, when the call area desired by the user is an area that is more expensive than the mobile phone usage fee, and the result of the determination of the state of charge of the mobile phone based on the signal of the charge detecting unit 18, the mobile phone can be used. By controlling the CO line switch 14 to release the connection state between the telephone station network and the general telephone period, and simultaneously controlling the communication unit 17 to transmit call command data to the mobile phone, it is possible to make a call through the cellular phone communication network instead of the general telephone station network. Do it.

Then, when an external telephone signal is transmitted through a general wired / wireless telephone network while the telephone is connected to the other party, the ring detector 13 detects this and inputs a detection signal to the central processing unit 19 to make an external telephone call. It is to be transmitted to the mobile phone through the communication unit 17 that has been caught. Therefore, the mobile phone user recognizes that the call is received from the outside by detecting a preset tone during the call.

When the cell phone call is completed, the central processing unit 19 detects this and controls the CO line switch 14 so that the CO line is transferred to the general telephone line network.

On the other hand, when the user presses the area code and the telephone number of the call partner by a general wired or wireless telephone, the processing result of the central processing unit 19 received a numeric signal through the receiver 12, or less than the mobile phone usage fee or If it is judged to be the same, it is necessary to maintain a call state by a general wired or wireless telephone without a switching operation to a separate mobile phone.

As described above, according to the mobile phone calling system using the wired / wireless telephone of the present invention, when a long distance call through the general wired / wireless telephone is controlled to allow a call by a general wired / wireless telephone or a mobile phone according to the determination result of the central processing unit, In addition to reducing, there is an advantage that can be conveniently used as a notification to the mobile phone user when another external call comes through the phone network during the call via the mobile phone.
