Embodiment 1

[0048] In areas with weak wireless network signal coverage, first start the extended AP;

[0049] The extended AP establishes a list of candidate APs for the surrounding main APs that support bridging services;

[0050] The extended AP monitors the beacon frame (Beacon) or probe response frame (ProbeResponse) of the surrounding main AP to confirm whether the main AP supports the automatic bridging service;

[0051] In this embodiment, a manufacturer-defined field is added in the Beacon frame (Beacon) or the Probe Response frame (ProbeResponse), which carries a flag to indicate whether the main AP supports the automatic bridging service. Specifically, as shown in the message content of the beacon frame (Beacon) shown in Figure 2 (a) and the message content of the probe response frame (ProbeResponse) shown in Figure 2 (b), obtain the custom manufacturer field dd0400534241;

Abstract

The invention provides a method and system for automatic expansion of a wireless network. When that a candidate AP switches on WDS bridge connection is determined, an expansion AP obtains the configuration information of the candidate AP. The expansion AP generates expansion AP configuration information according to the configuration information of the candidate AP and establishes the WDS bridge connection with the candidate AP. The expansion AP establishes CAPWAP bridge connection with an AC connected with the candidate AP through the WDS bridge connection. The method supports that the expansion AP matches with a main AP automatically after being electrified, so that the expansion of the wireless network is realized. Besides, the expanded wireless network supports monitoring and management; a problem that non-professional workers cannot arrange the WDS wireless network which can be monitored is solved and the network deployment cost is reduced.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a method and system for automatic expansion of a wireless network. Background technique [0002] In a large network topology, it is necessary to solve the deployment problem that some areas cannot be covered by signals. In a large campus or office environment, due to different structures and many obstacles, the signal attenuation of the wireless network is very large, resulting in insufficient signal coverage, especially in some areas where the wireless signal strength is weak, the wireless rate is low, and there are even wireless blind spots case, as attached figure 1 As shown, the user experience requirements for wireless networks cannot be met. [0003] In most cases, using a wired fixed network may not be able to meet the needs of users, and second, the cost of using a wired fixed network is too high; [0004] In large-scale parks or factories, generally spe...
