Embodiment Construction

[0017] 1. After the mobile node roams to the extended network domain, it normally registers to verify its identity, and at the same time establishes a tunnel path for communication with the basic network domain. At this time, the mobile node can realize the data transmission function of the traditional flexible IP network technology system;

[0018] 2. The mobile node uses the network equipment or other devices on the terminal to set or automatically obtain the IP address identity of the extended network domain. After success, the mobile node establishes the ability to directly access the Internet by using the extended network domain gateway;

[0019] 3. The mobile node actively sends an inquiry message to the basic domain management entity to query the Internet IP address set on the basic domain management entity that must be accessed by the basic domain management entity. After receiving the inquiry message, the basic domain management entity sends the corresponding basic netw...

Abstract

This invention relates to a communication method for adaptively selecting optimum paths by mobile nodes in a flexible IP network technology system. A mobile nodes actively inquires a basic domain management entity to get the Internet server list sponsoring access from the basic network domain and gets the idea that whether the current acc basic network domain host is another panning mobile node and judges if the data communication is sent to basic domain management entity after packaging the tunnel or accesses directly via the expansion network domain so that, wherever the access power same asin the basic network domain.

Description

technical field [0001] The invention belongs to the technical field of IP networks, and in particular relates to a data routing method for a mobile node when roaming in an extended network domain in a flexible IP network technology system, specifically a communication method for a mobile node to adaptively select an optimal path. The flexible IP network technology system mentioned in the present invention refers to the basic domain management entity, the extended domain management entity, the access management entity, and the mobile node. Nodes can achieve interactive access to their local area network at any time. Using the method of the present invention, the mobile node can automatically judge the communication capability and access authority of the basic network domain and the extended network domain after moving to the extended network domain, so as to ensure that the mobile node enjoys the communication capability in the basic network domain.
