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 establishe...

Embodiment Construction

[0053] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and examples.

[0054] The MP re-access method proposed by the present invention adds a configuration protection state to the MP. When the CAPWAP tunnel is interrupted, it enters the configuration protection state and uses the existing MESH link to try to restore the connection with the AC, which saves the time spent in the existing re-access method. The time spent in passive scanning, active scanning, trying to find neighbors and establishing temporary mesh links.

[0055] In fact, after the MP joins the MESH network, it has established a secure MESH link with its surrounding neighbors. If the CAPWAP tunnel is interrupted due to the loss of the keep-alive message, it will It saves a lot of time, that is, the existing MESH link and established neighbors of the MP are u...

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...
