Embodiment Construction

[0043] In order to make the above objects, features and advantages of the present invention more comprehensible, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0044] The invention provides a detection frame response method in a wireless local area network, which is applied to a network including an AP and a network side server. The AP and the network-side server may be a Fit AP and an AC (Access Controller, wireless access control device) respectively, or a Fat AP and a network-side server respectively. Among them, FitAP is an AP with encryption and radio frequency functions, which has a single function and cannot work independently. The FitAP wireless network solution consists of ACs and Fit APs based on a wired network. There is "zero configuration" on the Fit AP, and all configurations are centralized on the AC. The Fit AP solution is more convenient for centralized management, and...

Abstract

The invention discloses a response method and device of explore frames in the wireless local area network. The method includes the following steps: a network side server receives the measuring results of signal intensity of the same terminal appliance STA, which are reported by the device of each access point AP; the network side server selects a given amount of AP to respond to the explore frames of the STA according to the measuring results of the signal intensity reported by each AP. In the invention, the network side server selects a given amount of AP to respond to the explore frames of the STA on the basis of the received signal intensity of STA reported by each AP, thus effectively reducing the response quantity to the client explore frames by AP in the AP high-density deployment environment, reducing the empty port conflicts and improving the overall performance of the network without influencing the access and roaming service of clients. Besides, the method is compatible with the standards of the wireless local area network in the prior art with no need of any modification.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a method and device for responding to detection frames in a wireless local area network. Background technique [0002] The WLAN (Wireless Local Access Network, wireless local area network) technology provides a wireless connection service in a local area network, and has become one of the current popular technologies because it can provide high-speed wireless data access. WLAN has been widely used in cities, public places, and various places such as enterprises, buildings, and families. [0003] In airports, theaters, and training venues, it is often necessary to deploy WLANs in high density. In some places, multiple operators are even deployed repeatedly to provide their own services. In the prior art, a STA (Station, terminal device) discovers an AP (Access Point, access point) through a Probe (detection) frame. The STA not only sends a Probe frame for broadcasting an...
