Problems solved by technology
[0011] Although the draft proposes the service authentication and configuration method of the mobile node and the service authorization function of the home agent, there are still the following problems: the authorization information of the mobile node is only sent to the home agent, when the mobile node uses the two-way tunnel mode When using network services, the home agent can control the mobile node very well; but when the mobile node adopts the route optimization mode, the communication between the mobile node and the correspondent node no longer passes through the home agent, so the home agent cannot effectively control the mobile node to the network. resource usage, there is no way to realize the service authorization of the mobile node
[0012] To sum up, the existing IPv6 protocol cannot provide the ideal service authorization function for the mobile node when the mobile node is in a foreign network

Embodiment Construction
[0029] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0030] The invention provides a mobile node service authorization method, which mainly solves the service authorization problem of the mobile node in the routing optimization mode, and can also be applied to the mobile node service authorization process in the bidirectional tunnel mode. The main processing idea of this method is: during the moving process of the mobile node, when the mobile node moves to the external network, the home agent sends the authorization information of the mobile node obtained from the home AAA server to the access router, so that the access router According to the authorization information, the mobile node is controlled to use network resources.
[0031] Wherein, in order to send the authorization information to the access router, the home agent must first obtain the information of the access router from th...

The invention discloses a mobile node service authorizing method, applied to a system comprising: mobile node, home agency, home AAA server and access router of external network, where when the mobile node moves to external network, the home AAA server makes service authorization for the mobile node and then sends the authorizing information of the mobile node to the home agency; and the method also comprises: the home agency receives and transmits the authorizing information to the access router, and the access router receives the authorizing information and controls the mobile node to use the network service. And the invention also discloses a system. And the method and system can implement service authorization in various operating modes of mobile node.
Description
technical field [0001] The invention relates to mobile Internet protocol (IP) technology, in particular to a mobile node service authorization method and system in the mobile IP technology. Background technique [0002] With the rapid development of data communication and wireless communication technology, and the emergence of a large number of mobile terminals, such as notebook computers, personal digital assistants (PDA), mobile phones, vehicle-mounted equipment, etc., more and more users hope Efficient and flexible access to the Internet (Internet). The Internet will not only provide existing data services and multimedia audio and video services, but also realize the functions of the mobile Internet and provide mobile users with wireless Internet access services. Mobile IP is a technology that supports the interconnection between mobile users and the Internet to meet this demand. It can keep the communication between the user host and the Internet uninterrupted while mov...
