Embodiment Construction

[0028] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific examples.

[0029] The wireless local area network environment described in the present invention includes at least two wireless access points and two terminals. Two wireless access points form an extended service group to provide access services for two terminals. figure 1 It is a schematic diagram of the structure of the wireless LAN extended service group, such as figure 1 As shown, there are two wireless access points: wireless access point 1 and wireless access point 2. Each access point and its managed terminals form a basic service group, and two basic service groups work together to form an extended service group. The dashed oval line of the basic service group in the figure indicates the coverage of the wireless access point. There is some overlap in the coverage of the two basic service groups. Terminal 1 and Terminal 2 are terminals m...

Abstract

This invention discloses a load balance method for WLAN, which finds out the radio access point with the lightest load by negotiations among radio access points, and the current point is taken as the agent of the terminals to realize the whole switch queue to dispatch and control the switch of the terminals at the target point. Advantages: 1, since all switch requests and switch behaviors at the target access point are defined and sequenced in advance, and the load changes of the target point can be shown smoothly and orderly so as to avoid congestion on the target point, 2, the real switch time will be reduced and risk brough with switch will be reduced too since there is not switch competition, 3, the preparation period is decided by the current point of the terminals so service on terminals is not influenced.

Description

technical field [0001] The invention relates to a wireless local area network system in the communication field, in particular to a method for realizing load balancing in the wireless local area network. Background technique [0002] WLAN (Wireless Local Area Network) refers to the application of wireless communication technology to interconnect computer equipment to form a network system that can communicate with each other and realize resource sharing. In a WLAN network environment, an extended service group system consists of one or more basic service groups and distribution systems connecting these basic service groups, and each basic service group includes a wireless access point device. The extended service set is distinguished by ESSID (extended service set identification number), and the wireless access point is distinguished by BSSID (basic service set identification number). The terminal obtains the information of the extended service group and the basic service g...
