Abstract

The present invention is applicable to the technical field of network communication, and provides a distributed mobile network video cache placement method, system and related equipment. The method includes the following steps: establishing a distributed cache model of a cellular network, and the cellular network includes a macro base station With multiple micro base stations, the cellular network provides video services to micro users within the coverage area; the micro base station obtains a sub-video data from the macro base station through the regret minimum algorithm and places it in the cache; Calculate the popularity of the sub-video data, and delete the sub-video data in the micro base station according to the popularity; the micro base station calculates the cache probability according to the popularity, and delete the sub-video data that does not exist in the micro base station Caching is performed in the micro base station. The invention solves the problem that the traditional cellular network cannot reduce the transmission delay of mobile video data in the cellular network structure of the macro-micro base station.

Description

technical field [0001] The invention is applicable to the technical field of network communication, and in particular relates to a distributed mobile network video cache placement method, system and related equipment. Background technique [0002] In a traditional cellular network, a mobile terminal in the cellular network can only obtain the requested content from the macro base station, which is equivalent to forming a traditional cellular network, and the devices in the cellular network form a star network centered on the macro base station structure, which has high requirements on the carrying capacity of the macro base station, and will reach a performance bottleneck as the number of mobile terminal devices in the cellular network increases. [0003] In a wireless heterogeneous cellular network, by introducing cell base stations with content caching capabilities, micro base stations with caching capabilities can be used for local caching to reduce the backhaul link load...
