The present invention relates to a wired telephone network relay system and a method thereof. In particular, a mobile telephone sender sends a relatively low-cost one-time message or a counterpart's number to an Internet call to an exchange, and the terminal of the sender and the receiver is transmitted at the exchange. The present invention relates to a wireline telephone network relay system of a mobile phone that enables a mobile phone to be wired at a wire communication rate which is cheaper than a wireless communication charge by making a call through a wired telephone network or the Internet.

With the development of wireless communication technology and the continuous spread of mobile phones, the majority of people are using mobile phones, and the use of wired telephone networks is gradually decreasing.

The use of fixed line telephone networks continues to decline, and due to the current billing system in which charges are incurred at the original caller, the revenue structure of wireline telephone carriers is greatly deteriorating.

In addition, most mobile phone users have no negotiating power since the first caller is a wireless network to which they have subscribed, and even if the communication fee is high, they are forced to pay the communication fee set by their wireless carrier. There is no problem.

The current communication fee between wired / wireless telecommunications carriers is set at a higher rate than that used when calling a mobile phone using a wired telephone network. Mobile phone users are forced to pay high fees due to the constraint that the call must always start from the mobile phone, even though the call from the landline to the mobile phone is relatively inexpensive.

Therefore, there have been attempts to use mobile phone calls using wired telephone networks to solve this problem.

In Korean Patent No. 10-0473909, a method for accessing a wired telephone network of a mobile phone is automatically connected to a direct exchange through a connection number of an exchanger when the caller presses only the phone number of the other party to be called on the mobile phone. We proposed a procedure to use a wired telephone network at a lower price than the conventional method using only a wireless telephone network by making a wired telephone call to a receiver's mobile phone.

In the method using the access number, the mobile telephone caller enters only the number of the mobile telephone receiver and uses the access number on the calling mobile phone to access the exchange. The exchange calls the recipient's mobile phone using a wired telephone network to relay each other's calls. In this case, since calls to the switchboard and the receiver's mobile phone are initiated from the wired communication network, the charge can be saved compared to using the existing wireless communication network.

In the above method, the communication to the receiver's mobile phone of the exchange is saved by making a call on the wired network, but the communication between the mobile phone caller and the exchange starts on the wireless telephone network, so the saving in this part The disadvantage is that it is impossible.

In addition, since the first call is initiated from the wireless telephone network, there is a limitation that the final fee of the user must be determined by the wireless carrier to which the mobile phone is subscribed.

The present invention has been made to solve the above problems, the mobile phone caller sends a single message from the mobile phone or the number to be called through the Internet to the repeater, the repeater receiving the number to the terminal of each of the sender and receiver The present invention provides a wired telephone network relay system using a text message and a method thereof, which provides a cheaper fee than the conventional system because the telephones relay the communication with each other by using a wired telephone network or the Internet.

In order to achieve the above object, the wired telephone network relay system of the present invention uses the called terminal unit for transmitting the called party information of the called party and the calling party information of the called party and the receiver information received from the calling terminal unit. Attempt to connect to, and if the connection is made with the receiver includes a relay unit for connecting the sender and the receiver.

In the present invention, the recipient information is transmitted through a text message or the Internet, and includes at least one or more recipient information, and may include one or more pieces of information selected from a recipient's wired or wireless terminal telephone number, an Internet messenger ID, and a SIP address. Can be.

In the present invention, the caller information is a caller's wired or wireless terminal telephone number, and the caller terminal may be one type of terminal selected from a mobile phone, a landline telephone, and a PC.

The wired telephone network relay method of the present invention comprises the steps of receiving recipient information, determining whether the received recipient information is valid, connecting to the recipient, connecting to the caller when connected to the receiver, and when connected to the caller, Relaying the call of the recipient and the caller.

In the present invention, in the step of connecting to the receiver, if the connection fails after exceeding the number of retries set by the user, an error message may be transmitted to the sender.

In the present invention, in the step of connecting to the caller, if the connection fails after exceeding the number of retries set by the user, an error message may be transmitted to the caller.

In the present invention, if the transmitted receiver information is invalid, an error message can be transmitted to the sender.

Hereinafter, exemplary embodiments of the present invention will be described with reference to the accompanying drawings. In adding reference numerals to the components of the following drawings, the same components only have the same reference numerals as much as possible even if displayed on different drawings, it is determined that may unnecessarily obscure the subject matter of the present invention Detailed descriptions of well-known functions and configurations will be omitted.
