JPH10149325A - Inter-internet user direct connection function program and its system using ip address switching - Google Patents

Abstract

PROBLEM TO BE SOLVED: To enable the terminal users of an internet to mutually use it through the simple direct connection by notifying the internet users connected together via a public line of the IP addresses. SOLUTION: A server function program 1 is set in an internet to perform the centralized control of the current situation and the IP address of the terminal user who are logged in the internet. The terminal user of the internet has the client function programs 2a and 2b to send its own IP address and current situation to the program 1 and to receive the IP address of the terminal user of the opposite side who wants a dialog. Thus, the programs 2a and 2b can send its own IP address and current situation to the program 1, can receive the current IP address of the opposite party from the program 1 for the direct connection to the opposite party, and sends the received IP address to the communication systems 4a and 4b respectively.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for interactively connecting an Internet terminal user to a communication-requesting terminal user when the Internet terminal user dials up a communication network using a public line. The present invention relates to a function program for enabling communication and a system system thereof.

[0002]

2. Description of the Related Art Conventionally, there has been a method in which a communication destination of a terminal user desiring a conversation is acquired by some means, and the Internet terminal user issues a connection request and communicates with each other.

[0003]

This method has the following disadvantages. (B) To obtain the communication destination of the end user of the other party who wants to talk, it is troublesome and troublesome to directly call the other party and find out the current IP address. (B) In order to use the IP address once obtained, advanced knowledge such as which item of the interactive communication system should be designated and complicated procedures are required. The present invention has been made to eliminate these disadvantages.

[0004]

Means for Solving the Problems A server function program 1 for centrally managing the IP address of a terminal user who has logged in to the Internet and the current situation is provided on the Internet. Client function programs 2a and 2b are provided for transmitting the IP address and the current situation to the program 1 and for receiving the IP address of the terminal user who wants to talk from the server function program 1.

[0005]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Client function programs 2a and 2b of terminal users who have logged in to the Internet transmit their IP addresses and the current status to server function program 1, respectively. The destination IP address is received from the server function program 1 and passed to the interactive communication system 4a or 4b to request a direct connection.

[0006]

Embodiments of the present invention will be described below. (A) The server function program 1 is always operated on the Internet, and the client function programs 2a and 2
Wait for a connection from b. (B) The client function programs 2a and 2b store IP addresses assigned when dial-up connection is made to the server systems 3a and 3b of the Internet service provider (provider) with which the terminal user contracts using a public line. 1 and notify. (C) The server function program 1 stores and manages each IP address together with the current situation. (D) The client function program 2a requests the server function program 1 to notify the IP address of the other party to be directly connected. (E) The server function program 1 notifies the client function program 2a of the requested IP address together with the current situation to the client function program 2a, and informs the client function program 2b of the destination that a direct connection request has been received. Notice. (F) The other party client function program 2b receives the direct connection request, and the interactive communication system 4b
Activate and wait for reception. (G) The client function program 2a notified of the destination IP address from the server function program 1 passes the IP address to the interactive communication system 4a, starts up, and connects directly to the destination interactive communication system 4b.

[0007]

According to the present invention, the end users of the Internet, which are dial-up connected using a public line, can easily connect directly to each other and use the interactive communication system.
