  • Publication number: 20130067591
    Abstract: A method for filtering web page content is disclosed in this invention. In the method, a web page request to obtain a web page from a web server is received from a client through a network equipment after the client builds a connection with the web server. The network equipment transmits the web page request to a cloud server for determining if the web page needs to be blocked according to the web page request. A first disconnection request and a second disconnection request is generated according to the web page request if it is determined that the web page needs to be blocked. The first disconnection request is transmitted to the client and the second disconnection request is transmitted to the web server through the network equipment. Subsequently, the connection between the client and the web server is disconnected.

  • Patent number: 7664500
    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.
