Embodiment Construction

[0031] The present invention will be further described in detail below in conjunction with the examples.

[0032] Those skilled in the art will understand that the following examples are only for illustrating the present invention and should not be considered as limiting the scope of the present invention. If no specific technique or condition is indicated in the examples, it shall be carried out according to the technique or condition described in the literature in this field or according to the product specification. The materials or equipment used are not indicated by the manufacturer, and they are all conventional products that can be obtained through purchase.

[0033] Consider that the handover delay depends largely on the time spent on channel scanning. However, the "disconnect before connect" concept adopted by 802.11 greatly limits the improvement of handover performance and brings serious delay and uncertainty to the handover process. Therefore, the present invention...

Abstract

The invention relates to a wireless communication access network switching scheduling method for an edge computing environment, and belongs to the technical field of communication. According to the method, the AP information in the channel is acquired in advance by deploying the redundant virtual access point, so that the scanning of the channel without the AP is avoided, and the delay of scanningall unknown APs on the channel one by one by the terminal is reduced. And meanwhile, the safety of the detection stage is ensured by sensing the abnormality of the wireless channel in real time. Andthen, for the edge computing environment, influence factors such as the distance between the terminal and the AP, the QoS service level of the AP and the RSSI value of the AP are comprehensively considered according to the moving direction of the terminal, a weight factor is set according to different scenes, and the most suitable base station is recommended as a delivery point. By using the method, the load balance of the access point is ensured while the channel scanning time delay is reduced.

Description

technical field [0001] The invention belongs to the technical field of communication, and in particular relates to a wireless communication access network switching scheduling method oriented to an edge computing environment. Background technique [0002] With the continuous improvement of the intelligence of substations, there are more and more types of services that need to be connected to substations. Various services have different requirements for communication network quality, access location, and security. At the same time, there are many types of terminals in the substation, including: video surveillance terminals, power data collection terminals, on-site intelligent operation and maintenance terminals, etc., and each terminal often supports multiple types of services. Therefore, in order to change the redundant construction and complex operation and maintenance situation of the communication network brought about by the out-of-order requirements of the smart substat...
