Abstract

Embodiments of the present invention provide a cache placement method and device in a D2D network. The method includes: obtaining the user's contact duration and interval contact duration, dividing the file into multiple file blocks, and performing file block transmission according to preset rules, and obtaining from The average number of file blocks obtained from nearby users and the average number of file blocks obtained from the base station; the acquisition transmission cost, according to the transmission cost, contact time, interval contact time, the average number of file blocks obtained from nearby users and from The average number of file blocks obtained at the base station is used to obtain the average network consumption cost and the average file transmission delay; according to the average network consumption cost and the average file transmission delay, resource allocation is performed to obtain a cache placement set. The cache placement method and device in the D2D network provided by the embodiments of the present invention design a file cache placement scheme based on the minimization of average consumption cost, which solves the problem of the surge of mobile Internet video services in the mobile scene of user terminals.

Description

technical field [0001] The present invention relates to the field of network storage resource allocation, in particular to a cache placement method and device in a D2D network. Background technique [0002] With the popularization of smart phones and the development of mobile Internet, wireless data traffic has exploded in recent years. Communication services have also changed from traditional voice and SMS services to emerging services with large capacity and low latency such as live video, online games, augmented reality, and virtual reality. [0003] To cope with the pressure of explosive growth in mobile data traffic, the ultra-dense cell network architecture can improve network capacity by reducing the coverage radius of each cell, deploying multiple base stations densely, and increasing the frequency reuse factor. Although this solution can increase the peak rate of the air interface of the wireless network, it brings great load pressure on the backhaul link of the ne...
