The present invention relates to a wired / wireless internet interworking system and method for P2P content sharing, and more particularly, to a system and method for using a wired / wireless interworking IP based network IMS (IP Multimedia Subsystem) network and a P2P technology over the Internet of a next generation mobile communication system. will be.

Currently, there are P2P content sharing programs such as sound seas and donkeys in the wired Internet, and if connected to the Internet, content can be freely shared among individuals. On the other hand, the wireless terminal environment must use a wireless Internet service provided by a telecommunication company to share content. It is not yet free because of lack of communication charges or autonomy of access to provide free services separately from telecommunication companies that provide telecommunication services. In other words, the wired Internet can be freely shared if only the Internet is connected, but the wireless Internet cannot freely share contents due to lack of communication charges and autonomy of access.

Wired Internet is a PC environment that can store and share a lot of contents through a large storage space, whereas a terminal can store and share only a few contents in the terminal due to limited storage space. In addition, since only one network port is opened for communication, it is not suitable for a traditional client / server environment and a communication environment for P2P. In addition, the performance of the terminal itself is also very slow compared to a general PC, so it is not suitable for many data processing and transmission. In the existing communication environment, direct communication between peers for content sharing is impossible in a network separated by a NAT (Network Address Translation) device or a firewall.

With the development of mobile communication system, IP-based multimedia service functions have been enhanced in mobile communication terminals on Code Division Multiple Access (CDMA) 2000 or Wide Code Code Division Multiple Access (WCDMA). The need to share the need has become urgent, and in particular, a service method that can be shared by using a P2P scheme to overcome the limited resources of the wireless terminal.

 Accordingly, an object of the present invention is to provide a system and method for passing through an isolated network to overcome the disconnection of real-time content and information sharing through limited resources of a wireless terminal.

The present invention relates to a wired / wireless internet interworking system and method for P2P content sharing, and more particularly, to a system and method for using a wired / wireless interworking IP based network IMS (IP Multimedia Subsystem) network and a P2P technology over the Internet of a next generation mobile communication system. will be.

Wired and wireless Internet interworking system for P2P content sharing of the present invention, after logging in, the wireless terminal peer to be synchronized with the virtual peer; A relay peer created therein to communicate with the radio peer; A rendezvous peer interworking with the virtual peer and enabling to locate the peers; And a peer group connected to the wireless terminal peer on the Internet and providing contents to each other based on a P2P scheme.

The wired / wireless internet interworking method for P2P content sharing of the present invention includes a first step of a content provider logging in to a peer group providing a content sharing service using an ID and a password; A second step of the content provider creating a virtual peer which is its own space in the relay peer; A third step of the content provider synchronizing the virtual peers in the radio peer with the relay peer; And providing a corresponding content preset by the content provider to peers shared by other users based on a P2P scheme.

Relay peers provide a mechanism by which peers can also communicate with peers within a network separated by NAT (Network Address Translation) devices or firewalls. The relay peer acts as an intermediary so that peers outside the firewall can communicate with peers inside.

To send a message through a relay peer, you must first decide which relay peer to use to communicate with the destination peer. This routing information provides a DNS-like mechanism within P2P to find devices that connect intermittently to dynamic IP. The approach is similar to DNS converting names to IP addresses. Routing information provides a mapping between an identifier that points to a remote peer within the network and a representation that can be used to connect to a remote peer through a relay peer. do.

In the case of a simple system, routing information may consist of an identifier consisting only of an IP address and a TCP port. More complex systems may include a series of relay peers in the routing information used to properly deliver messages to the peer. Routing messages through multiple relay peers is necessary when two peers want to communicate with each other in two or more incompatible network environments.

Hereinafter, with reference to the accompanying drawings, the configuration and operation of the embodiment of the present invention will be described in detail.

1 illustrates a wired / wireless internet interworking system for P2P content sharing according to the present invention. The peer in the wired / wireless internet interworking system for P2P content sharing of the present invention includes all types of network peers that can be connected to the Internet. That is, the present invention is not limited to PCs or other server-class terminals, which are generally considered, and mobile communication terminals such as Code Division Multiple Access (CDMA) 2000 or Wideband Code Division Multiple Access (WCDMA), notebook computers using wireless LANs, and personal digital assistants (PDAs). Includes all terminals that can access the Internet, such as assistant). In particular, as a mobile communication system evolves, a mobile communication terminal can access a wireless Internet using a mobile IP, and a mobile communication terminal other than a PC regarded as a peer of a conventional P2P is a main peer of a P2P. In FIG. 1, the PDA 40, the server terminal peer 50, and the PC 60 are described as examples among various peers.

The wireless terminal peer 10 is a mobile communication terminal, a laptop, a PDA 40, a server terminal peer connected to a wireless LAN horizontally on the Internet through a login process and a synchronization process with the virtual peers 20a and 20b. 50) and the PC 60 can be directly connected.

The relay peer 20 has virtual peers 20a and 20b created therein, and the virtual peers 20a and 20b communicate with the radio terminal peer 10. The wireless terminal peer 10 and the virtual peers 20a and 20b are always synchronized, and the communication between the wireless terminal peer 10 and the virtual peers 20a and 20b communicates using an HTTP polling scheme. HTTP polling method is based on TCP to send or receive data using POST / GET method. Whenever a transaction is received, the server receives an HTTP message, opens a TCP socket, and then disconnects. In other words, if HTTP is used, a request cannot be made from the relay side to the terminal because the connection is not always made like a TCP connection. Therefore, if a terminal periodically transmits data to the relay using a polling method, the terminal transmits the data using the POST. If there is data to import, it is imported using GET. If there is no data to import, the connection is terminated. After all the communication process is performed by the virtual peers 20a and 20b, only the result is transmitted through the synchronization process with the radio peer 10.

The rendezvous peer 30 cooperates with the virtual peers 20a and 20b and enables the location of the peers.

Peer groups are peers connected to the wireless terminal peer 10 on the Internet, such as CDMA 2000, WCDMA, notebook computer, PDA 40, server terminal peer 50, PC 60, and the like. They are horizontally connected to the wireless LAN and directly connected to the wireless terminal peer 10, and provide contents to each other based on a P2P scheme.

2 is a flowchart illustrating a wired / wireless internet interworking method for P2P content sharing according to the present invention. The method of sharing contents between wireless and wired terminal peers based on P2P on various Internet including IMS network of mobile communication system is as follows.

First, the content provider logs in to a peer group that provides a content sharing service with an ID and password. Peer groups may include PCs, server-class terminals, CDMA 2000, WCDMA, notebooks and PDAs using wireless LAN.

The content provider then creates a virtual peer that is its own space within the relay peer. The creation of the virtual peer is for communicating with the radio peer.

The content provider then synchronizes the virtual peers within the radio peer with the relay peer. After the virtual peer performs all the communication process, it transmits to the wireless peer through synchronization.

Next, the content provider presets the content to peers shared by other users based on P2P technology. These peers are horizontally connected to the WLAN and directly connected to the wireless peers.

It will be apparent to those skilled in the art that various changes and modifications can be made without departing from the technical spirit of the present invention through the above description. Therefore, the technical scope of the present invention should not be limited only to the contents described in the embodiments, but should be defined by the claims.

As described above, the wired / wireless Internet interworking system and method for P2P-type content sharing according to the present invention share a content between a peer using a wireless Internet and a peer using a wired Internet on various Internets including a mobile communication system or a WLAN. In order to overcome the limited resources of the wireless terminal, a relay peer is provided so that the mobile communication terminal directly participates in the P2P service, thereby enabling direct content sharing between peers of the mobile terminal, thereby increasing the efficiency of using the wireless network.
