The present invention relates to a data sharing method and an index server for sharing data stored in a mobile communication terminal with another mobile communication terminal using a mobile communication terminal.

The method of sharing data using peer-to-peer method is different from the existing Server-Client concept. The distribution of contents consisting of various multimedia data and the provision of services related to the downloading of such contents are performed in a form in which a general user receives a service through a server provided by a specific CP (content provider) through his PC.

This server-client method is a system in which suppliers and consumers are strictly separated. If a large number of clients are concentrated on the server, data bottlenecks can occur and the server-side system can be overloaded. The same quality of service is determined, and if there is a problem with such a server, there is a problem that all subscribed users will have a problem receiving service.

On the other hand, unlike the general method of searching for information on the Internet through a search engine and downloading the information stored in the server-side database, the P2P type service receives information directly from a personal computer connected to the Internet. Of course, this means that you can download data. The P2P service has an advantage that the load can be distributed without being concentrated on one computer or server since data is transmitted from each personal computer connected through the Internet. In addition, since data is transmitted between users having data of common interest, it is also possible to form an interactive community (club) between users who share data.

These P2P systems are divided into three types according to their form. One is pure P2P, and there is no dedicated server in any form, for example Gnutella or Soribada2. In the centralized method, the server keeps only the location and index information of each peer in the server and performs the search. When downloading, the server finds the location of the peer related to the data and sends and receives the actual content. It is a form that is performed between Peer and Peer without passing through. Napster and Sori are the methods, but if peers illegally distribute paid contents, legal measures such as server closure are made, so pure P2P type is preferred. In another form, there are several small servers in a hybrid form, which are connected in a hierarchical manner.

However, this P2P system is only possible between a series of PCs connected to a virtual network by being performed based on TCP / IP. This type of P2P service was sufficient to meet the needs of users in previous generations when wireless communication technologies and devices were not developed, but it is not suitable in today's wireless communication-based society.

An object of the present invention is to provide a data sharing method and an index server for data sharing, which enables a user to receive various multimedia contents through a mobile communication terminal by providing a P2P service using a mobile communication terminal.

The providing-side mobile communication terminal may further include uploading the entire data of the data to the index server, and if at least one index information is selected from the index information searched by the receiving-side mobile communication terminal, the index information selected by the index server is selected. Transmit the data related to the mobile communication terminal.

Further, the index information of the data or the entire data is stored separately in individual or community-specific storage spaces of the index server, and the fee is used for the providing-side mobile communication terminal according to the current data storage capacity of the storage space or the total capacity provided. It is characterized by charging.

In addition, the billing relating to uploading of the index information of the data or the entire data is provided to the providing mobile communication terminal, or the billing relating to the downloading of all the data is performed to the receiving mobile communication terminal.

In addition, when the provider-side mobile communication terminal uploads the index information or the entire data about the data for sharing to the index server, a guide message for the uploading to the receiving-side mobile communication terminal belonging to the same community as the providing-side mobile communication terminal is sent. Characterized in that the transmission.
