System and Method for providing lettering service

The present invention relates to a lettering service providing system and method for providing lettering services between Internet phone terminals, between an Internet phone terminal and a mobile communication terminal, and between an Internet phone terminal and a wired network terminal.

The communication system is a real-time connection and communication with a desired destination terminal by a calling terminal, and is generally classified into a wired communication system when a terminal and a subscribed terminal are connected by wire, and a wireless communication system when connected wirelessly.

INNET NETWORK is a network that connects a number of local networks controlled by HUB computers to form a global connection. A number of communication paths are formed between the other parties. have.

Terminals connected to the Internet network include computers (PCs) and data terminals, and each terminal is classified into an IP (INTERNET PROTOCOL) address, and a packet of a certain size is packed using a TCP (TRANSMISSION CONTROL PROTOCOL) protocol. It can be transmitted in units and can transmit a large amount of data such as E-mail, documents, photos, and videos. In the case of transmitting a large amount of data, the serial number is assigned to the data classified in packet units by the TCP protocol, and the receiving side waits until all the packets are received, reassembles them in order, and provides them to the receiver.

In each packet, the overhead including the source IP, the reception IP, the packet serial number, the data size, and the information data to be transmitted are recorded, and the overhead is analyzed by the gateway controlling the internet network.

Each gateway stores the packet when the received IP of the analyzed packet indicates its own domain, and if not, the packet is forwarded to the neighboring gateway, so that each packet is finally delivered to the destination computer or terminal. . In addition, the hub computer managing each domain stores the received packet and delivers it directly to the destination computer or the destination terminal by the destination IP address through a reassembly process.

In general, the communication method through the Internet network transmits data in multiple paths, so that information is securely transmitted, and since the received information can be checked at any time by the receiving terminal after recording the received information on the hub computer, it can be accurately and repeatedly checked. have. Due to the improvement of data processing speed of the hub computer managing each network of the Internet network and the development of connection line and communication hardware and software technology, it is possible to transmit packet data at high speed and the related technology is gradually improving.
