Embodiment

[0042] This embodiment shows the use of the content cache deployment method in the mobile edge cloud. The solution of the present invention consists of two parts: user demand prediction and content cache deployment. The following is combined with the attached figure 2 A flow chart of content cache deployment in a mobile edge cloud disclosed in the present invention specifically illustrates the solution of the present invention, and the implementation of the solution includes the following steps:

[0043] First, build the system model of the mobile edge cloud, which is a two-layer heterogeneous network architecture with controllers composed of macro base stations and micro base stations, such as figure 1 As shown, the macro base station is referred to as MBS, and the micro base station is referred to as SBS. Each cell is equipped with an MBS, and the communication between MBSs is realized through optical fiber connection, and each MBS can be connected with the remote core clou...

Abstract

The invention discloses a content cache deployment method in a mobile edge cloud, and the method combines mobile edge calculation and multicast routing, constructs a macro cell-micro cell two-layer heterogeneous network architecture with a controller, and solves a multi-cell cooperative cache problem. On the basis of the architecture, a content cache deployment problem in the mobile edge cloud isconverted into a 0-1 integer programming problem, and a cache deployment method for solving the problem is provided. According to the method, multicast delivery is used as an entry point, the popularity and delivery delay of a file are used as deployment bases, the delivery delay is optimized by combining a collaborative caching algorithm based on multicast and popularity perception and an improved ant colony optimization multicast algorithm, a content caching deployment mode capable of reducing the total delay of a system is found, and hotspot content is reasonably pre-cached in an edge server. According to the method, the delivery time delay is reduced, so that the user service quality is improved, and meanwhile, limited network resources are efficiently utilized to respond to the requirements of 5G low time delay, high bandwidth and large connection.

Description

technical field [0001] The invention relates to the technical field of mobile edge cloud infrastructure and its cache deployment and content delivery, in particular to a content cache deployment method in a mobile edge cloud. Background technique [0002] Since the end of 1978, mobile communication has developed from analog communication technology to digital communication, and now in the 4G era, 3GPP-led LTE technology has become a globally unified technical standard, network bandwidth has been greatly improved, and data services have also become popular. The continuous improvement of mobile communication networks and the gradual introduction of new mobile devices such as smartphones and tablets have spawned various applications for mobile connectivity, followed by an explosive exponential growth in network traffic. Smart mobile terminals also play an indispensable role in entertainment, life, study, office, multimedia and other aspects. With the birth of 5G, applications ...
