Roaming switching control method and device and electronic equipment

Abstract

The invention discloses a roaming switching control method and device and electronic equipment, and the method comprises the steps: carrying out the sampling according to a preset sampling time interval, and obtaining the current state information of a network system where a current wireless AP connected with a to-be-roamed client is located; inputting the current state information into a preset fuzzy inference system, and according to a preset fuzzy inference mechanism in the fuzzy inference system and a rule set containing a plurality of fuzzy logic rules, performing inference to obtain roaming quality determined by downlink signal intensity corresponding to each wireless AP and the load quantity of the client; determining the optimal roaming quality from all the roaming qualities, and taking the wireless AP corresponding to the optimal roaming quality as a target wireless AP; and controlling the to-be-roamed client to roam from the current wireless AP to the target wireless AP. According to the invention, the roaming switching control can be carried out by adopting the rule set suitable for the wireless network environment, and the most suitable target wireless AP can be accurately determined.

Description

technical field [0001] The present invention relates to the technical field of roaming handover, in particular to a roaming handover control method, device and electronic equipment. Background technique [0002] Roaming refers to a process in which a client switches from one wireless AP (ie, wireless access point) to another wireless AP. Due to the limited power and limited coverage of wireless APs, in the same network system, usually multiple wireless APs are needed to ensure the coverage of the network. Roaming switching, switching to re-association connection with other wireless APs. [0003] Most of the existing wireless AP roaming strategies use the relationship between the signal strength between the client and the wireless AP and the signal strength threshold as the basis for handover judgment to realize wireless roaming. For example, the wireless AP periodically monitors the RSSI value of the client, and Compared with the signal strength threshold, when the monitor...

Problems solved by technology

[0004] However, the communication quality of the wireless network may change over time due to interference factors, for example, factors such as different altitudes, temperature and humidity, and occlusion of the connection link between the wireless AP and the client. , the signal strength threshold is a fixed value. It is a fixed roaming strategy to judge the network link quality only by the RSSI value and the signal strength threshold. It is impossible to adopt a roaming strategy suitable for the current network environment after the wireless network communication quality changes. Unable to accurately determine the most suitable target wireless AP
