Description

Interoperation system and method between Internet and Advanced Intelligent Network

The present invention relates to a next generation intelligent network service providing technology, and more particularly, to an Internet-next generation intelligent network bearer gateway station for interworking with the Internet and the next generation intelligent network.

There is an increasing number of studies to link the Internet, which is currently in explosive demand, with other networks. While the International Telecommunication Union has been working on the interworking between the Intelligent Network and the Internet, it presents a need for a gateway between the Internet and the Intelligent Network. Has not been released yet.

Currently, a technology for delivering voice packets on the Internet is called a Voice Over Internet Protocol. The background of the development of such a technology is as follows.

First, Frame Relay technology was developed as a high-speed packet switching service that developed X.25 technology, which is synonymous with packet switching. The frame relay supports switched-oriented services to provide switched virtual circuits and permanent virtual circuit connections, improving network performance and usability, simple network management, and low network costs. Has

On the other hand, Internet telephones are in the spotlight because they use the Internet instead of a dedicated line for telephones, and the charges are low, and general subscribers have reached saturation. The Internet phone is growing at a rapid rate of more than 300% per year, and Internet phone users are expected to outpace the number of users soon. In particular, Internet telephony is capable of various applications such as video telephony, Internet fax, voice mail, text transmission, whiteboard, and the like, and all telephone networks are currently being integrated into the Internet.

If the caller is a computer (PC) and the receiver is a regular phone, the method of operation of the Internet phone is that the caller connects to the gateway station (gateway) of the recipient area via the Internet connected to the computer (PC), The caller is connected to the receiver by connecting the receiver through a telephone line. Here, the gateway station is a system that allows mutual compatibility between the telephone network and the Internet network.

Looking at the operation principle of the Internet phone, when transmitting, it receives the micro-voice, converts it to analog / digital conversion, compresses it, and transmits it by packetization. . However, this technique also has a disadvantage of delay characteristics, and in order to overcome this, instead of TCP / IP, a protocol supporting real-time traffic transmission such as RTP / UDP / IP should be used.

Recently, a protocol called Session Initiation Protocol / Session Description Protocol (SIP / SDP) has been developed by the Internet IETF (Internet Engineering Task Force).

Accordingly, an object of the present invention is to provide an internet-to-generation intelligent network bearer gateway station using a session initiation protocol / session description protocol for an internet host belonging to an internet network to use a next generation intelligent network service.

The user 101 using an internet host has a specific icon on an application program having a graphical user interface (GUI) form. When the next generation intelligent network service is started by clicking, it is transmitted to the service control system 104 through the Internet-Next Generation Network Control Gateway Station 102. The Internet-Next-Generation Intelligent Network Control Gateway Station 102 is a network element for service interworking between the Internet network and the next-generation intelligent network. The Internet network protocol and signaling based on Transmission Control Protocol / Internet Protocol (TCP / IP) It is in charge of protocol conversion function between next generation intelligent network service control system based on system No.7 (SS No.7: Signaling System No.7).

The service control system 104 is a network element that is in charge of controlling the next generation intelligent network service. When the service request is received from the Internet-Next Generation Network Control Gateway Station 102, the service control system 104 drives the next generation intelligent network service logic. The intelligent information providing system 106 is a network element that provides special resource services (information broadcasting, dual-tone multi frequency (DTMF) collection, voice recognition, fax provision, media conversion, etc.) among the next generation intelligent network components. When a voice service request from the service control system 104 occurs, the voice service is provided to the Internet host 101 via the service switching system 105, the Internet-Next Generation Network Bearer Gateway Station 103.
