Description

Free Internet phone connection service system

The present invention relates to a free Internet dial-up service system, and more particularly, a phone to phone or a telephone to connect a receiving party using a number dialed by a landline phone, a wireless phone or a mobile phone even when a user cannot directly access the Internet. The present invention relates to a system for enabling a free telephone provided on the Internet in the form of a phone to PC.

Even in the early 1990s, some of those who knew how to use a computer, the Internet, which some of them used as their own means of communication, are now a necessity to be able to use without a computer. Also known as a passport. One of the decisive moments of the popularization of the Internet is the Web.

Recently, various services such as e-commerce, e-advertisement and internet phone are provided based on such internet web, and internet service is the most as the users can easily receive the service that was performed physically through the internet. It is emerging as an important business.

On the other hand, Internet free telephones generally used over the Internet are provided in the form of PC to Phone or PC to PC in the form of VoIP through TCP / IP (Transmission Control Protocol / Internet Protocol).

Here, Voice over Internet Protocol (VoIP) refers to IP telephony technology for a series of facilities that use IP to convey voice information, and are not discrete protocols based on circuits such as PSTN, a public switched telephone network. It means sending voice information in digital form within packets.

The main advantage of VoIP and Internet telephony technology is that it integrates telephone service by utilizing existing IP network so that telephone users can receive long distance and international phone service in internet and intranet environment with only local call charge.

In addition, VoIP is being used by Cisco, Vocaltec, and 3Com through VoIP forums to encourage the use of ITU-T H.323, a standard for transporting voice (sound) and video over IP over the public Internet or intranets within the enterprise. And major equipment manufacturers such as NetSpeak. The VoIP Forum also encouraged directory service standards, enabling users to locate other users and enabling the use of touch phone signals for automatic telephone distribution and voicemail.

In addition, VoIP uses a real-time protocol (RTP) to support packets arriving in a timely manner, in addition to the original IP functionality. With public networks, it is currently difficult to guarantee quality of service (QoS) Better service can be achieved by using a private network managed by an enterprise or an Internet telephony service provider (ITSP).

The technique used by equipment makers, called NetSpeak, to ensure fast packet delivery, pings all network gateways connected to the public network before establishing a TCP socket connection with the other party, and based on the result, To choose.

In order to use VoIP, companies must install VoIP equipment, such as Cisco's AS5300 access server, at the gateway, which receives packets divided into packets from users in the company and forwards them to other parts of the intranet. You must send them to the PSTN using the -1 or E1 interface.

In the case of a free Internet phone used in this way, a call is made with the other party only in the form of a PC to Phone or a PC to PC by accessing the web.

However, such a service has an inconvenience that a user should always be connected to the Internet, and also has a disadvantage in that a computer system and a communication infrastructure such as a leased line or a modem must be provided to access the Internet.

Accordingly, the present invention was devised to solve such a problem, and an object of the present invention is to connect a receiving party using a number dialed by a landline phone, a wireless phone or a mobile phone even in a situation where a user cannot directly access the Internet. It is to provide a service system that allows to use the free phone provided on the Internet in the form of Phone to Phone or Phone to PC.
