Problems solved by technology

[0006] 1. Since the relevant information of the MIH service is statically configured inside the mobile node and cannot be changed arbitrarily, when the mobile node roams or nomads to a visited network, the configured MIH service-related information (including MIH ES, MIH CS, MIH IS ) to the upper layer, because the configured MIH service-related information may be different from the MIH service information of the visited network where the mobile node is located, and the configured MIH service-related information cannot be changed, and the scalability is poor, so it is difficult to realize that the mobile node operates in different locations. Structured network or seamless switching between homogeneous networks
[0007] 2. Since the relevant information of the MIH service is statically configured inside the mobile node, with the development of wireless communication technology, the number of mobile nodes is increasing, and the work of configuring the relevant information of the MIH service for each mobile node is heavy

Embodiment Construction

[0037] An embodiment of the present invention provides a method for obtaining MIH service information. The method includes: receiving an MIH service request message sent by a mobile node, obtaining the MIH service information requested by the mobile node; sending a response message carrying the MIH service information to the mobile node. When the mobile node roams to the visited network, it can dynamically obtain MIH service information.

[0038] image 3 It shows the architecture diagram for obtaining MIH service information provided by the embodiment of the present invention, which describes the connection relationship between the MIH service and the visited network, home network and third-party network. In this architecture diagram, four logics are introduced Functional entities and 6 service interfaces.

[0039] The four logical functional entities are:

[0040] MIH service server, AAA (Authentication, Authorization, Account) authentication server, network access server ...

Abstract

The invention discloses a method for obtaining MIH service information, comprising: receiving medium irrelevant MIH service switching request message sent by mobile nodes, obtaining MIH service information requested by the mobile node; sending response message with MIH service information to the mobile node. Using the technical scheme provided by the invention, MIH service related information is dynamically obtained.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a method for obtaining media-independent switching service information, network element equipment and a network system. Background technique [0002] With the development of wireless communication technology, there are currently many networks with different architectures, such as Wireless LAN (Wireless LAN, WLAN), Worldwide Interoperability for Microwave Access (WiMAX), and 3GPP. Business continuity needs to be ensured during handover and roaming. figure 1 Provides a block diagram for assisting and optimizing heterogeneous network handover services. The Media Independent Handover protocol (Media Independent Handover, MIH) is between the L2 layer and the L3 layer, providing link layer information and other related network information to the upper layer to optimize handover , so that the mobile node can automatically select the connection network type and access point with ...
