AP (access point) power adjustment method, AC (access controller) and AP

Abstract

Transmission power regulation of a wireless access point (104) is described. In a method, a first indication of signal quality of a signal received by the access point (104) from a terminal (106) is acquired. An indication of a communication failure between the access point (104) and the terminal (106) is also acquired. Further, a second indication of signal quality of a signal received by the access point (104) from the terminal (106) after such an indication of communication is acquired. The first and second indications of signal quality are compared and the transmission power of the access point (104) is regulated according to the result of the comparison.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to an AP power adjustment method, an AC and an AP. Background technique [0002] WLAN (Wireless Local Area Network, Wireless Local Access Network) technology provides wireless connection services in local area networks. Because it can provide high-speed wireless data access, it has become one of the current popular technologies and has been widely used in cities, Public places are covered, as well as various places such as enterprises, buildings, and families. [0003] AP (Wireless Access Point, Access Point) and AC (Access Controller, Access Controller) are currently commonly used devices when building a WLAN. Among them, the AP is used to provide the bridging function from the STA (terminal equipment, Station) of the wireless network to the LAN, and performs frame conversion from wireless to wired and from wired to wireless between the STA of the wireless network a...

Problems solved by technology

[0006] However, existing technical solutions easily cause STAs to lose signal coverage

For example, when the AC automatically lowers the power of the AP, the signal coverage of the wireless network is also reduced accordingly. At this time, the STA at the edge of the coverage is likely to be unable to search for wireless services and lose the connection; When the original signal coverage of the AP is lost, the AP cannot perceive whether the STA is leaving or malfunctioning
