MOBILITY MANAGEMENT METHOD AND SYSTEM FOR P2P NETWORK

摘要

Mobility management method for a peer to peer (P2P) network is provided, the method comprises that when a user cross-domain roaming is judged by network side (301), a boundary service node is selected in a visit domain of the user, and services are provided to the user by the boundary service node (302). A mobility management system for P2P network is provided correspondingly. The present invention provides services to the user by using the boundary service node when the terminal cross-domain roaming, the signaling roundabout route of terminal roaming can be shortened, thereby services processing time-delay can be shortened, and the user experiences can be improved.
