ABSTRACT:
A network service control method detects whether a mobile node communicating with a corresponding node is trending to a second local area network from a first local area network and forks and transmits a user agent and a server agent to a proxy when the mobile node is trending to the second local area network. After that, the user agent registers onto the proxy according to a result obtained by the handshaking. Finally, when the mobile node moves into the second local area network, the mobile node communicates with the user agent for obtaining a connection tunnel reserved by the user agent to communicate with the corresponding node.
