Method for selecting wireless access point and wireless access point

Abstract

The invention provides a method for selecting a wireless access point and the wireless access point. The method comprises the following steps that: a master control access point (AP) selects candidate APs according to a terminal access signal intensity threshold value and a preset threshold value of the master control AP and other APs; the master control AP acquires information of a terminal and the candidate APs, and performs assignment on an attribute array according to the acquired information, wherein the attribute array comprises signal intensity between the candidate APs and the terminal, the access capabilities of the candidate APs, a channel utilization rate and a signal-to-interference ratio; the master control AP calculates the weight coefficient vector of the attribute array, and calculates recommended values of the candidate APs according to the weight coefficient vector and the attribute array; and the master control AP sequences the candidate APs according to the recommended values of the candidate APs and provides a sequencing result for the terminal, so that the terminal can select an AP according to the sequencing result. By the technical scheme, the AP is selected on the basis of a plurality of attributes, so that the terminal can successfully access a network and participate in normal services according to the selected AP.

Description

Technical field [0001] The present invention relates to wireless communication technology, in particular to a wireless access point selection method and wireless access point. Background technique [0002] A wireless local area network refers to a computer network that uses wireless channels as a transmission medium, enabling users to achieve broadband network access anytime, anywhere, and at will. In a wireless local area network, a terminal, such as a personal computer (PC) or other portable device, searches for available wireless access points (AP) by sending radio signals, and when it searches for a wireless signal with a considerable strength, it will Establish a wireless connection with the corresponding AP, so as to achieve access to the network through the AP. [0003] The terminal accesses according to the signal strength of the AP. The signal strength only indicates that it can connect to the AP. However, when the capacity of the AP selected by the terminal according to ...

Problems solved by technology

[0003] The terminal accesses according to the signal strength of the AP. The signal strength only indicates that the AP can be connected. However, when the capacity of the AP selected by the terminal according to the signal strength of the AP is full, there are enough users and the traffic is large enough, and there is no extra bandwidth allocated to the AP. This terminal, or when the channel interference of this AP is serious, resulting in poor signal quality, this terminal can only access this AP, but cannot really carry out business

It can be seen that the method that the terminal selects an AP based on the signal strength does not guarantee that the terminal can successfully access the network.
