The present invention relates to a method for preventing malicious call reception using a password in a toll service, and more particularly, a method of determining a user and a receiver using a toll service and recording a name informing them of the service when using the service or after making a short call. Instead, the present invention relates to a method of preventing subscribers subscribing to a toll payment service to pay an unfair rate by allowing each other to use a password promised to each other.

At present, telephone is widely used as the most common means of communicating with people in daily life, and generally, the caller pays the call charge. However, in the case of ordinary telephone users who do not have cash or phone card, the service is available if the receiver can only check the user, and parents with military service soldiers or children who are out of the country are willing to pay for the calls from their children. There is a tendency.

And in various aspects, the toll charge service is a simple and easy way for users to make a call without paying a call charge, but it has problems depending on how the caller can check the user who makes the call. .

This is a method to check the user calling the recipient in the current toll-paying service.When the user enters the recipient's telephone number and records his / her name, the recipient who receives the call listens to the recorded user name and decides whether or not to make a call. There is a method of making a call and a caller who decides whether to talk with the user after a while.

However, in the case of a method of recording a user's name, if the user using the telephone hears a prompt to record his name and saves the malicious recording without recording the name, the receiver will receive the call in a situation where the other party may not be known. This can cause complaints to subscribers, and the method of talking for a while is also complicated to identify the user. In addition, small businesses that provide services, such as ponting, using some automated answering systems (ARS) provide their members with ARS phone numbers and toll-payment service identification numbers, and intentional phone calls to members. In some cases, a DTMF tone is recorded for a specific digit that determines whether or not a call is made at the beginning of ARS announcements.

In view of the conventional problems described above, the present invention provides a method for preventing a malicious call and reducing a complaint caused by a prank call, instead of recording a name for a caller who uses the toll charge service. If the receiver wants to talk to the user who wants to talk with the user, input the password promised with the user, and make the call possible only when the password entered by the user and the receiver match. The goal is to implement a method to prevent this.

In order to achieve the above object, the present invention provides a method for providing a toll charge service,
A first process of inputting a telephone number and a password of a receiver who wants to call from a user who wants to use the toll service, a second process of connecting a call to the telephone number of a receiver input from the user, and a receiver telephone number When a call is connected, the receiver is notified that a call using the toll charge service has occurred, and a third step of requesting a password is input, and if a password is input from the receiver, whether the password input from the receiver matches the password input from the user. And a fourth process of determining, and a fifth process of making a call connection if the comparison result is matched.

The above objects, features and advantages will become more apparent from the following detailed description taken in conjunction with the accompanying drawings. Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a block diagram of an intelligent network system for a service when a call is made in a general telephone network to which the present invention is applied, and includes a calling local exchange 105 which receives a service call from an intelligent network service user 106 using a telephone of the general telephone network;

An intelligent network service exchanger (SSP) 103 connected to the originating local exchange 105 for delivering an intelligent network service call;

A common line signaling network (CCSN) 102 for delivering service control information to the intelligent network service exchange 103;

An intelligent information providing system (IP) 104 connected to the common line signal network 102 for receiving a receiver's telephone number and password pressed by the user and transferring the received telephone number and password to the service control system 101;

A service control system (SCP) 101 connected to the common line signal network 102 and receiving a password input by a user and a receiver from the intelligent information providing system 104, and determining whether or not a match exists;

A service management system (SMS) 100 connected to the service control system 101 for managing service data necessary for processing a service;

An incoming local exchange 107 which receives the called number from the intelligent network service exchange 103;

And a service subscriber 108 connected to the incoming local exchange 107 to receive services.

2 shows a message configuration of the service control system according to the present invention. First, the user's call number 21 with the information 20 about the user, the telephone number 22 of the receiver who wants to make a call, and the user presses A password 23 is provided. In addition, the information 30 on the receiver includes a receiver call number 31, a receiver password 32 inputted for making a call with the user, and a password mismatch number 33 for limiting the number of password retries. .

In FIG. 3, after receiving the service identification number input by the user from the intelligent network service exchange using the service control system message shown in FIG. 2 in the intelligent network structure as shown in FIG. 1, the service control system receives the user from the intelligent information providing system. Is a flow chart showing a process of receiving and receiving a phone number and password of a receiver who wants to call and determining whether it matches the password inputted by the receiver from a service control system perspective.

With the service identification number received from an unspecified number of users, the service logic of the service control system (SCP) 101 provides intelligent information on the recipient's telephone number and password that the user wants to call. After receiving from the system (IP) 104, the number is reconfirmed (S1).

Subsequently, if the reconfirmed recipient number and password match, the service logic of the service control system 101 based on the recipient number informs the recipient of the call that he / she wants to call. The telephone number is transmitted to the intelligent network service exchanger 103 as the called number, and the intelligent network service exchanger 103 receiving the number connects the user and the receiver using the recipient telephone number as the called number (S2).

When the connection with the receiver is successful, the service logic additionally requires the receiver password to confirm whether the receiver has a willingness to talk with the user. The intelligent information providing system 104 collects the password inputted by the receiver and the service control system ( 101) (S3).

Subsequently, the service logic of the service control system 101 compares the receiver password received from the intelligent information providing system 104 with the password of the user and connects the user with the receiver to make a call (S4).

In addition, the receiver considers the caller and the intention to call a password incorrectly and sends a password re-entry announcement so that the user can retry for a given number of times. If not (S5).

For reference, due to the characteristics of the toll-bearing service for unspecified number of people, it is not premise to subscribe to the service. Therefore, the recipient's phone number and password entered by the caller are temporarily stored in the intelligent network service control system. The system does not need to manage the password separately because it compares with the password entered by the user and the receiver who is willing to talk to the phone. The password used above uses a random 4-digit number, Any one of four to four digits (for example, two digits, etc.) may be used to increase service convenience.

As described in detail above, the present invention enables a call when the recipient's phone number and password entered by the user match the password entered by the user, thereby intentionally exploiting cases or mischievous cases of business operators doing business through some ARS. This has the advantage of preventing the phone call, and therefore, the communication resources used to store and manage voice messages in the conventional name recording method can be used for other purposes, which entails the advantage of improving the efficiency of the communication resources. .                     

In addition, preferred embodiments of the present invention are disclosed for the purpose of illustration, those skilled in the art will be able to various modifications, changes, additions, etc. within the spirit and scope of the present invention, such modifications and modifications belong to the following claims You will have to look.
