Abstract
A Peer-to-Peer (P2P)-based network apparatus and system is provided. The P2P-based network apparatus may sense the movement of a mobile station (MS), select a candidate proxy, and change a proxy of the MS to the candidate proxy.
Claims22
A peer-to-peer (P2P)-based network apparatus, the apparatus comprising:
- a movement sensing unit configured to sense movement of a mobile station (MS);
- a candidate proxy selection unit configured to select a candidate proxy server based on state information of each of neighbor proxy servers, in response to the movement of the MS being sensed;
- and
- a data packet forwarding unit configured to
- forward a migration request message to the candidate proxy server, the migration request message comprising an internet protocol (IP) address of the MS, and a correspondent peer (CP) list comprising an IP address of a CP device connected to the MS via a P2P connection through the apparatus, and
- forward a data packet destined for the MS to the selected candidate proxy server in response to a confirm migration request message being received from the candidate proxy server.

A peer-to-peer (P2P)-based network apparatus, the apparatus comprising:
- a message receiving unit configured to
- receive a migration request message from a proxy server, the proxy server selecting a candidate proxy server based on state information of each of neighbor proxy servers, in response to movement of a mobile station (MS) being sensed, and the migration request message comprising an internet protocol (IP) address of the MS, and a correspondent peer (CP) list comprising an IP address of a CP device connected to the MS via a P2P connection through the apparatus, and
- receive a proxy registration request message from the MS to register the MS;
- a data packet receiving unit configured to receive a data packet destined for the MS from the proxy server;
- a packet buffering unit configured to buffer the received data packet;
- and
- a data packet forwarding unit configured to forward the buffered data packet to the MS, in response to the MS being registered.

A peer-to-peer (P2P)-based network apparatus, the apparatus comprising:
- a message receiving unit configured to receive a proxy change request message from a proxy server configured to sense movement of a mobile station (MS), select a candidate proxy server based on state information of each of neighbor proxy servers, in response to the movement of the MS, and forward a migration request message to the candidate proxy server, the migration request message comprising an internet protocol (IP) address of the MS, and a correspondent peer (CP) list comprising an IP address of a CP device connected to the MS via a P2P connection through the apparatus;
- a registration setting unit configured to set a registration of the P2P-based network apparatus in the selected candidate proxy server;
- and
- a data packet receiving unit configured to receive, from the selected candidate proxy server, a data packet, buffered in the selected candidate proxy server, in response to the registration being set.

A method of changing a proxy server in a mobile peer-to-peer (P2P)-based network, the method comprising:
- selecting a candidate proxy server based on state information of each of neighbor proxy servers, in response to movement of a mobile station (MS);
- forwarding a migration request message to the candidate proxy server, the migration request message comprising an internet protocol (IP) address of the MS, and a correspondent peer (CP) list comprising an IP address of a CP device connected to the MS via a P2P connection through the proxy server;
- forwarding a data packet destined for the MS to the selected candidate proxy server in response to a confirm migration request message being received from the candidate proxy server;
- and
- forwarding a proxy change request message to the MS.
