Repeated accessing method of wireless access point of MESH network and wireless access point equipment

Abstract

The invention provides an MP repeated accessing method adding a configuration protection state to an MP. When a CAPWAP tunnel is interrupted, the MP enters the configuration protection state, maintains a prior MESH link and tries to recover the CAPWAP tunnel to an AC by the prior MESH link. The invention also provides MP equipment adopting the repeated accessing method. The MP repeated accessing method and the MP equipment save the time consumed during passive scanning, active scanning, trying to search a neighbor and establishing a temporary MESH link, thereby shortening the interruption time of an MESH network service caused in such a way that a CAPWAP keep-alive message is lost and enhancing the stability and the service quality of an MESH network.

Description

technical field [0001] The invention relates to mobile communication technology, in particular to a MESH network wireless access point re-access method and wireless access point equipment. Background technique [0002] At present, the application of wireless network is expanding day by day, and the application of wireless local area network (WLAN) mesh (MESH) network technology is also more and more extensive. The centralized control MESH network is a common wireless network architecture. Its typical structure is as follows: figure 1 hint. see figure 1 , in the centralized control MESH network, the MESH network wireless access point (Mesh Access Point, MP) is managed and controlled by the access controller (Access Controller, AC), and the wireless access point is established between MP and AC Control and Provisioning of Wireless Access Points (CAPWAP) tunnel, the AC sends management control information to the MP through the CAPWAP tunnel, and forwards data packets; the MP...

AI Technical Summary

Problems solved by technology

The above process is executed repeatedly, and it takes several minutes or even ten minutes to rebuild the CAPWAP tunnel, which takes too long, and the MESH network service of MP is interrupted during this period.

[0016] In the case of unfavorable environmental conditions, for example, there is interference in the channel within a certain period of time, or the MP moves at a high speed and constantly establishes or closes the MESH link with the surrounding MPs. In this environment, CAPWAP often occurs. The keep-alive message of the tunnel is lost, so both the MP and the AC will judge that the CAPWAP tunnel is disconnected, so the MP must perform the above re-access process, resulting in the interruption of the MESH network service for several to ten minutes, thus making the quality of the MESH network service very poor
