Abstract

The embodiment of the invention provides a caching method and system. The method includes: for each user in a user group served by any edge node, a request content from a user at a target time is predicted according to a historical request record set of the user within a preset period of time; incomes obtained by caching the request content are obtained and the corresponding request contents are cached to the edge node successively according to the incoming sequence. According to the method and system, with the historical request record from the user, the user request behavior characteristicscan be explored fully and the request content from the user at a certain time in future can be predicted accurately. Moreover, the income obtained by caching each request content is calculated and thecorresponding request content is cached based on the income sequence, so that the cache space of the edge node is utilized efficiently and the request delay is reduced.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of caching, and in particular, to a caching method and system. Background technique [0002] By caching content copies, the Mobile Content Delivery Network (MCDN) offloads the traffic locally, achieving ultra-low data transmission latency, which paves the way for high bandwidth-intensive services (such as augmented / virtual reality, etc.). Although this kind of heterogeneous network and ultra-dense base stations are indeed effective in handling the ever-increasing video traffic, the deployment of high-speed backhaul links that match the large wireless access bandwidth is very expensive. Very stringent requirements were put forward. To address the mismatch between radio access bandwidth and backhaul links, one achievable way is to utilize wireless edge caching. Network operators can store requested content at network edge nodes such as micro base stations, thereby shortening user re...
