Embodiment Construction

[0021] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0022] In edge network areas with relatively high population density, such as airports, shopping malls, railway stations, schools and other areas where wireless network sharing exists, when users use wireless networks to upload their generated content (such as video images, etc.), there may be poor upload experience. question. One of the important reasons for this is that some APs (wireless access points) have a heavy load and cannot complete the upload requests made by users connected to them, but at the same time, the number of users connected to some APs in this area is small. In some cases, load balancing between APs can better solve this problem. Therefore, the present invention proposes a wireless network load balancing method. Based on D2D (device-to-device) communication, the method transmits the content that cannot be uploaded by the ...

Abstract

The invention discloses a wireless network load balancing method. Each wireless access point participating into load balancing is subjected to the following steps of S1, judging whether the number of concurrent content upload requests received by the wireless access point within a current slot exceeds the maximum permissible concurrent upload number M of the wireless access point, if no, executing the steps S2, and if yes, executing the step S3, wherein M is not less than 1; S2, executing all concurrent content upload requests received within the current slot by the wireless access point; and S3, ranking content to be uploaded corresponding to the concurrent content upload requests according sums of cache income indexes from small to large, and assigning the content to be uploaded ranked at the first M to be uploaded by the wireless access point; and meanwhile copying the other content to be uploaded to assistant cache equipment to assist caching, thus allowing the assistant cached content to be connected to the other wireless access points along with the assistant cache equipment and uploaded by the other wireless access points.

Description

technical field [0001] The invention relates to the technical field of wireless communication, in particular to a wireless network load balancing method. Background technique [0002] With the development of wireless communication technology and smart mobile devices, mobile users are more and more inclined to use 802.11 wireless local area network (Wi-Fi) to upload audio, video, pictures and other content. However, in a wireless local area network with a high user density (such as airports, venues, etc.), due to too many tasks uploaded concurrently, the wireless access point (AP, Access Point) of the edge network is overloaded, so that it cannot bring users Come to a good upload experience. [0003] Existing methods to improve user experience by increasing the number of APs or increasing the upload bandwidth of APs not only require high hardware deployment costs, but are also difficult to meet the increasing upload bandwidth requirements of users. At the same time, due to ...
