Problems solved by technology

Obviously, obtaining user interest and social activity information will add additional computing and processing power, increasing the complexity and difficulty of caching
However, with the continuous development and rapid application of 5G, users' demand for ultra-high-definition video and low-latency applications is increasing exponentially. Simply formulating a cache strategy based on user historical request information cannot meet the growing needs of users.

Abstract

The invention relates to a mobile edge caching method based on regional user interest matching, and belongs to the technical field of caching. The method comprises the following steps: S1, establishing a regional user preference model; S2, establishing a joint cache optimization strategy; S3, establishing a cache system model; S4, designing a cache algorithm. When a cache mechanism of the invention is used, the video caching gain can be maximized under the condition that the diversity of cached videos is met, compared with a current caching mechanism, the video caching benefit and QoE of a user can be effectively improved, and an effective solution is provided for caching and online watching of large-scale ultra-high-definition videos in a future 5G scene.

Description

technical field [0001] The invention belongs to the technical field of caching, and relates to a mobile edge caching method based on regional user interest matching. Background technique [0002] The current research on mobile edge caching is mainly divided into two aspects. One is the research on cached content to solve the problem of what content to cache, and the other is the research on caching strategy to solve the problem of how to cache and where to cache. Due to the difficulty in predicting the popularity of content, popular content is greatly influenced by users and shows great variability in spatio-temporal distribution. There is a big difference between global popular content and regional popular content, which increases the difficulty of cache content selection. It also poses a challenge to the operator's cache revenue. However, for densely populated places such as user communities, offices, and campuses where users are relatively fixed, user needs are easier to...
