A c-ran-based Internet content cache preloading method and system

Abstract

The invention discloses a C-RAN-based Internet content cache preloading technology. According to the classification of the requested resource, query the corresponding cache directory. If the requested content exists in the local cache directory, directly return the corresponding content to the user. If the requested content does not exist in the cache directory, query the cloud platform server cache directory again. If there is still no When the query is found, the corresponding resources will be obtained through the Internet and returned to the user, and the cached and uncached access content will be counted separately, and the user preference will be obtained according to the user's access record, and the composition ratio of the user label will be analyzed; when the heat value reaches the upper limit or the composition ratio of the label When the change exceeds the threshold, the cache preloading unit is triggered to apply to the background server for preloading the cache. Aiming at the development of future mobile communication, the present invention realizes the optimal storage of content cache in the whole network, improves the utilization rate of storage, effectively saves settlement costs between networks, and improves user experience.

Description

technical field [0001] The embodiment of the present invention relates to the field of communication technologies, and in particular to a method and system for preloading Internet content cache based on a Cloud-Radio Access Network (C-RAN). Background technique [0002] With the commercialization and widespread deployment of 4G networks, users can enjoy increasingly high-speed data services. The rich applications of the mobile Internet, such as OTT, social networking, file download, real-time video, etc., have further stimulated the use of mobile devices (smart machines, tablets, etc.) by users. According to the traffic data forecast report released by Cisco in February 2014, from 2013 to 2018, mobile data traffic will grow at a compound annual growth rate of 61%. Therefore, the downlink traffic load of the cellular network increases sharply, and the workload of network equipment increases greatly. The transmission link is congested, and the end-to-end link path of the dat...

Problems solved by technology

Such a deployment has certain advantages, however, in the existing technical solution, the access hit rate of the Internet content stored in the base station is relatively low in this existing content storage and query mode

For operators, the utilization rate of cache storage is also low, the economic benefit is not obvious, and it is in a passive cache "pipe", and the user perception is poor; from the user's point of view, the storage space of the base station is limited, and the Internet cannot be obtained in time The hot content on the Internet, the content accessed by users can only be loaded through the network connection, which affects the user experience

[0006] In addition, there is currently no Internet content storage system that is aimed at the future mobile communication network architecture, so the inventor proposes a forward-looking C-RAN-based Internet content cache preloading method and system
