WIFI automatic association method and intelligent terminal

Abstract

The invention provides a WIFI automatic association method and an intelligent terminal. The WIFI automatic association method includes the steps that the intelligent terminal STA conducts a preliminary screening on a monitored AP collection according to a busy degree and signal strength of each wireless access point AP; STA calculates jamming intensity of each AP according to average bottom noise of a communication channel and the busy degree and the signal strength of each AP, and rechecks the AP collection after the preliminary screening according to the ratio of the signal strength to the jamming intensity; STA calculates the decision function value of each AP in the AP collection after checking according to an optimal AP decision function; STA selects the AP to be associated with according to the busy degree, the signal strength, a signal-to-jamming ratio and the decision function value of each AP after rounds of selection. According to the technical scheme, the WIFI automatic association method and the intelligent terminal comprehensively consider coverage, capacity, interference, switching calling loss and switching expense and conduct WIFI automatic association, and web surfing experience of a user in a WIFI network is improved.

Description

technical field [0001] The invention belongs to the technical field of communication, and in particular relates to a WIFI automatic association method and an intelligent terminal. Background technique [0002] With the development of multimedia business requirements, wireless local area network WLAN (Wireless Local Area Networks) with strong mobility, flexible networking and strong scalability is popular. Wireless local area network is a very convenient network based on IEEE802.11 standard Data transmission system, which uses radio frequency (RF) technology to replace the local area network formed by the old twisted-pair copper wire (Coaxial) that hinders the hands and feet, so that the wireless local area network can use a simple access architecture, allowing users to use it. While freeing from the shackles of network cables, you can enjoy high-speed wireless access and at the same time move freely within the network, achieving the ideal state of "portable information and c...

Problems solved by technology

[0007] It can be seen that in the prior art, the terminal only selects WIFI based on signal strength and load, resulting in STAs being concentratedly associated with APs with high signal strength, while APs with low signal strength will remain idle, resulting in load fluctuations among APs. Causes a decrease in the utilization of network resources, and even causes network congestion
