Abstract

PURPOSE: A telephone set allowed for a call communication only through a specific number is provided to artificially induce a user to connection to a system of a provider by limiting use of a dial button unless the user inputs a connection button to use a phone set. CONSTITUTION: A dial controller(200) controls an oscillator(400). A connection button(201) and a dial control switch(300) operate the dial controller(200). The connection button(201) is directly connected to a dial circuit(100) to activate a memory. Even though a user picks up a receiver, the oscillator(400) is not operated. When the connection button(201) is inputted, a call is connected to a system of a provider and a dial operation signal is applied from the dial controller(200) so that the user can use a dial button(500). For this purpose, when the user picks up a receiver, an output voltage of the dial controller(200) is connected to a ground, so that an input voltage of the oscillator connected to the output voltage is grounded. Then, since the oscillator(400) can not apply a frequency to the dial circuit, the user can not use the dial button(500). When the connection button is inputted, an output terminal of the dial controller(200) and the input terminal of the oscillator(400) are cut off, so that a high voltage is applied to the input terminal of the oscillator(400) and the oscillator applies a frequency to the dial circuit, to operate the dial button(500). A specific number stored in a specific address of a memory of the dial circuit(100) is transmitted through an office line, so that the user can connected to the provider system and makes a phone call to the other party by using the dial button.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a telephone having an authentication button for connecting to an operator's system in a wired / wireless telephone. In particular, when the user does not input a connection button when using the telephone, the user is restricted from using the dial button. It is characteristic of the structure of the telephone that can artificially induce connection to the system.

In order to access the service of a particular operator's system, the current user only has to enter a large number of buttons to access the system of the operator, and after pressing the telephone button of the other party after accessing and authenticating the service, , The method of use is complicated, and the button is pressed a lot. Because of this, the user can directly connect to the other party without using the above services because of the complexity of use and the hassle of pressing a button even though the user can use the phone using the above service to reduce phone costs and receive differentiated services. It is being used. Some users access the user's system by using the speed dial function by storing the specific number to access the user's system in memory, but in this case, the user's system asks questions such as entering a password and selecting various services. Therefore, the user has to press a button, which is quite cumbersome for the user.

With the development of communication means and the flood of information as in modern times, the use of telephones is increasing day by day, and as a result, the communication expenses of general households are increasing exponentially, while the functions of telephones are not able to cope with high speed and differentiated services. The user is currently unable to properly use the differentiated services that are cheap and variously provided.

Accordingly, an object of the present invention is to provide a telephone that can be easily connected to the service provider's system to solve the above problems.

In addition, the present invention is to provide a telephone that enables the operation of the dial button only after connecting to the operator's system, the user can artificially induce connection to the operator's system.

To this end, the present invention is to provide a telephone having a connection button that is provided with a connection button, the connection button that can be automatically connected to the operator's system just by entering the connection button once.

In addition, the present invention is to provide a telephone having a separate dial control switch in order to enable the operation of the dial button without inputting a connection button in case of emergency.

The number stored in the access button in the above may be input at the time of manufacture of the phone, the user may be input by the operation of the dial button, which is a technology that can be applied by those skilled in the art according to the situation in this specification Detailed descriptions are omitted.

In order to achieve the above object, the telephone set of the present invention is a conventional telephone set comprising: a connection button for connecting to an operator's system, a dial control circuit for controlling a dial button, and a dial control for applying a signal to the dial control circuit. It is equipped with a switch and consists of additional electrical circuitry to allow the above components to achieve the desired purpose. Conventional use of the telephone is connected to the other party through the CO line after inputting the number with the dial button 500 through various processes of the internal circuit of the telephone, the operation of the dial button is continuous in the oscillator 400 to the dial circuit 100 Only when the frequency is input. Therefore, the conventional telephone is configured such that when the user picks up the handset, the oscillator 400 inputs a frequency into the dial circuit.

The telephone of the present invention focuses on the fact that the conventional telephone controls the operation of the dial button by the oscillator, so that the user does not operate the access button 201 or the dial control switch 300 while the oscillator does not operate even when the telephone is picked up. When the signal is manipulated, the oscillator 400 applies a frequency to the dial circuit 100 so that the dial button 500 operates. In other words, when a user makes a call through the telephone of the present invention, the call must be made by using a connection button, so that the user is naturally connected to the operator's system. In the telephone of the present invention, when a user applies a signal through an access button, two operations occur at the same time. One of them is to apply a frequency to the dial circuit through the oscillator so that the dial button 500 can operate, and the other sends a specific number stored in the memory 150 embedded in the dial circuit to the trunk line. To immediately access the provider system. Therefore, although the user of the telephone of the present invention is required to press the access button, the dial button is operated at the same time immediately connected to the operator's system without any time delay, it will be easy to use the differentiated services at a low price. In addition, the telephone of the present invention is provided with a dial control switch. The dial control switch is inevitably provided in case the connection button cannot be used. When the user operates the dial control switch, the dial button is enabled by allowing the oscillator 400 to apply a frequency to the dial circuit. Therefore, in case of an emergency or when you want to make a direct phone call with the other party, it is possible to use the above dial control switch.

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

To facilitate understanding of the telephone of the present invention, a conventional telephone will be briefly described with reference to FIG. 1. FIG. 1 is a block diagram schematically illustrating a conventional telephone circuit, and is mainly composed of three parts. The circuit includes a ring control circuit 600, a dial circuit 100, and a counterpart. It is divided into Speech Circuit 700, which controls conversation. The telephone call can be divided into a method of directly inputting a dial button and a method of transmitting a telephone number stored in a memory. In the former case, when a user picks up a handset, the oscillator 400 of the dial circuit has a frequency in the dial circuit. Since the use of the dial button is enabled by applying the user, the user makes a phone call by directly inputting the dial button. In the case of using the latter memory, when the memory operation button is input, the dial circuit 100 connects the telephone number stored in the corresponding memory corresponding to the signal to the trunk line through the voltage control circuit through a speech circuit. Be sure to

Fig. 2 is a schematic block diagram of adding a dial circuit control unit 1, which is a key component of a telephone according to the present invention, to a conventional telephone. The dial circuit controller 1 includes a dial control circuit 200, a dial control switch 300, and a connection button 201.

First, in the conventional phone structure, a dial control circuit 200 capable of controlling the oscillator 400 and a connection button 201 and a dial control switch 300 for operating the dial control circuit 200 are provided. In addition, the connection button 201 is directly connected to the dial circuit 100 serves to activate the memory. The telephone of the present invention is configured such that the oscillator 400 does not operate even when the user picks up the handset, and when the connection button 201 is input, the telephone is connected to the operator's system and the dial control circuit 200 applies the dial operation signal to the user. The dial button 500 is configured to be used. To this end, when the user lifts the handset, the output voltage of the dial control circuit 200 is connected to ground, so that the input voltage of the oscillator connected to the output voltage is also grounded, and the oscillator 400 applies a frequency to the dial circuit. Since it is impossible to do so, the use of the dial button 500 becomes impossible. Then, in order for the dial button 500 to operate, the connection between the input terminal of the oscillator 400 and the dial control circuit 200 is cut off, which is configured to be possible by inputting the connection button 201. That is, when the connection button is input, the output terminal of the dial control circuit 200 and the input terminal of the oscillator 400 are cut off, and a high voltage is applied to the input terminal of the oscillator 400, and the oscillator applies a frequency to the dial circuit to dial the button. Let 500 operate. In addition, by simultaneously transmitting the specific number stored in the specific address of the memory of the dial circuit 100 through the trunk line, the user can make a telephone call to the other party through the dial button after accessing the operator system. .

The role of the dial control switch 300 is to block the connection of the output terminal of the dial control circuit 200 and the input of the oscillator 400, thereby enabling the operation of the dial button. Therefore, when the user wants an emergency call, the dial button can be operated by using the dial control switch 300, and a corresponding call can be made by inputting the corresponding number.

3 is a block diagram showing the relationship between the dial circuit control unit 1 and the peripheral circuit according to the present invention. First, look at the configuration and role of the dial control circuit 200, the pulse detector 210 detects an external signal, the voltage output unit 220 receives the external signal and serves to change the voltage, voltage control The switching circuit 230 is connected to ground when the voltage is high and is cut off when the voltage is low.

Hereinafter, a process according to the input of the connection button will be described.

When the access button 201 is input, two processes occur at the same time. First, the first process will be described, a pulse signal is generated by the connection button input, the pulse signal is detected by the pulse detection unit 210 of the dial control circuit 200. The detected pulse signal is applied to the input terminal of the voltage output unit 220, and the voltage output unit 220 is applied to the voltage control switching circuit 230 by converting the pulse signal into a low voltage. As described above, since the voltage control switch 230 is connected to the ground at a high voltage and is cut off at a low voltage, a low voltage is applied from the voltage output unit 220 so that the voltage control switching circuit is applied. 230 is isolated from the oscillator. The oscillator thus applies a constant frequency to the dial circuit, enabling the operation of the dial button.

In the second process that occurs simultaneously with the first process, since the line of the connection button 400 is directly connected to the memory address of the dial circuit 100, when the signal of the connection button 201 is input, the dial circuit 100 A pulse is applied to the pulse detection unit of the s), and the signal is connected to the operator system by sending a specific number stored in the corresponding memory address to the trunk line through the speech circuit 700.

In the case of urgent need of the user, the oscillator 400 is operated through the dial control switch 300. When the dial control switch 300 is pressed, the procedure for operating the oscillator using the connection button 201 is the same. Is omitted.

Fig. 4 shows a flowchart of making a call by connecting to a specific telephone with a conventional telephone. When the user wants to use the service, he enters a specific phone number for accessing the operator system (step 12), waits for a call, and enters a password again (step 13). After that, you can make a telephone call (step 15). From the user's point of view, after entering a specific number to access the operator's system, the user must enter a password and the other party's number according to the instructions. Cumbersome. Therefore, in the step of determining whether to use the service (step 12), the user places a telephone call by inputting the phone number of the other party (step 14) without accessing the operator's system.

Figure 5 shows a flow chart for making calls using the telephone of the present invention. If the user wants to connect to the operator's system, the user simply inputs the access button (step 22). The access button input step is easy to use because it processes not only the specific number to access the operator's system but also the input of the password. Since the telephone call (step 25) can be made by inputting the other party's number (step 24), it can be seen that it is very convenient compared to the conventional method of FIG. If an emergency call is required, a telephone call can be made using the dial control switch (step 23). Therefore, the user can immediately access the service provider system by simply entering the access button once, and the user having the phone of the present invention can easily use a differentiated service at a low price because no password or other confirmation is required. Could be.

6 shows a flow chart of the role of the dial control circuit 200 according to whether a connection button is used. When the user presses the access button (step 31) to access the operator's system, the dial control circuit causes the oscillator of the dial circuit to operate (step 32), and sends the number corresponding to the service provider access number (step 33). Access to the operator system (step 34). After that, the user enters the other party's number (step 37) to make a phone call. If you want to use the phone urgently, the user uses the dial control switch (step 35) to allow the oscillator to operate (step 36), and then enters a counterpart number using the dial button 500 to make a phone call.

The configuration of the circuit for executing the above flow chart may be implemented through various methods at the skill level of those skilled in the art, all of which belong to the technical idea of the present invention. In addition, the present invention does not limit the operation mode and form of the connection button and the dial control switch. In the initial use of the telephone, the step of storing the access number of the operator and later changing and storing again can be implemented in various ways at the technical level of those skilled in the art, all of these methods are obviously within the technical scope of the present invention. .

By using the telephone invented by the present invention, the user can easily access the operator through the access button. Therefore, since the user can conveniently use differentiated services at a low price and attract many users from the operator's point of view, it is obvious that this phone is a necessary phone for both the user and the operator.
