Problems solved by technology

This manual configuration solution has the following disadvantages: when adding/deleting an AR, it is necessary to change the configuration of all ARs adjacent to the AR, and the workload is heavy, resulting in poor scalability of the solution; when the network IP address needs to be re-deployed In this case, the configurations on all ARs need to be changed manually, and the workload is huge, resulting in poor maintainability; moreover, this solution cannot adapt to the dynamic adjustment of the network topology. For example, when an AR crashes, the adjacent ARs cannot Change setting
[0017] This solution has the following disadvantages: since the construction of AR information must be triggered by the mobile n

Example Embodiment

[0041] In order to make the objectives, technical solutions, and advantages of the present invention clearer, the following examples illustrate the present invention in further detail.

[0042] Fig. 2 is a schematic diagram of a network model for collecting AR information in FMIPv6 according to an embodiment of the present invention. Referring to Figure 2, in this embodiment, an AR information collection router (AR-ICR) is installed in the access network. The AR-ICR receives the AR information of each AR and sends the AR information of each AR to the same AR. Other ARs in adjacent locations. In Figure 2, AR-ICR is connected to each AR in the access network, such as AR1, AR2, AR3; each AR has an AP connected to it, for example, AR1 is connected to AP11, AP12, AR2 is connected to AP21, and AR3 is connected to AP31, AP32 is connected. Let us assume that AR1 and AR2 are adjacent ARs at the same position, and AR3 is an AR that is not adjacent to either.

[0043] The following describes...

Abstract

This invention discloses a method for collecting AR information by setting AR-ICR in an access network including the following steps: A, AR transmits one or more than one update messages of AR information to AR-ICR, B, AR-ICR sends said AR information to adjacent AR at a same position. This invention also discloses a system for collecting AR information including AR-ICR and at least two AR, which can collect AR information automatically without triggering mobile nodes or artificial configuration.

Description

technical field [0001] The invention relates to the technical field of mobile communication, in particular to a method and system for collecting access router (AR) information. Background technique [0002] In recent years, with the rapid development of data communication and wireless communication technologies and the emergence of a large number of mobile terminals, more and more users hope to access the Internet (Internet) efficiently and flexibly regardless of location. Therefore, the Internet not only needs to provide existing data services and multimedia audio and video services, but also needs to implement mobile Internet functions to provide wireless Internet access services for users' mobile devices. Mobile Internet Protocol (IP) is a hotspot technology that supports the interconnection between mobile devices and the Internet to meet this demand. It can enable user hosts to maintain communication with the Internet without being interrupted while moving. [0003] As ...
