Embodiment Construction

[0029] The present invention will be further described below in conjunction with accompanying drawings and examples.

[0030] Such as figure 1 As shown, the present invention provides a cellular heterogeneous network caching strategy based on intergroup caching, comprising the following steps:

[0031] Step 1. Build a system model

[0032] The research focus of the present invention is on the caching strategy under the cellular heterogeneous network, so the core network and the remote network server are simplified and regarded as a remote file library together. It is assumed that N adjacent SBSs constitute an SBS group and are considered as a whole at the cache level. Each SBS shares its cache content with other SBSs in the group through a wireless or wired backhaul connection. Define a symmetric matrix d i,j ∈D N×N , 1≤i, j≤N to represent the distance between two arbitrary small base stations in the group. d here i,j Used to indicate when SBS i want to transfer to SBS...

Abstract

The invention discloses a cache method based on inter-group cooperation under a cellular heterogeneous network. The cache method based on inter-group cooperation under the cellular heterogeneous network comprises establishing a cellular heterogeneous network system model; formulating energy performance indexes and generating a problem to be optimized; and solving the optimization problem with thesimulated annealing algorithm. The invention describes the detailed process of the provided cellular heterogeneous network caching strategy based on the inter-group cooperation, and stipulates and analyzes the file caching mechanism of each base station. By means of the technical scheme disclosed by the invention, the network system model is established reasonably in the scenario of the cellular heterogeneous network; and the corresponding caching strategy is formulated; therefore, the energy consumption of the network is reduced.

Description

technical field [0001] The present invention belongs to the related field of wireless communication, and in particular relates to a cellular heterogeneous caching method based on intergroup cooperation, which divides the traditional wireless network into two layers: a macro base station (Macro Base Station, MBS) and a small base station (Small Base Station, SBS). , expand the capacity of the network, and at the same time use the cache technology to cache the corresponding file fragments in each base station, reducing the amount of files requested by the backhaul, thereby reducing the overall energy consumption of the network. technical background [0002] With the rapid development of modern Internet communication technology, the bandwidth capacity provided by the network is also rapidly enhanced, which makes users tend to support the behavior of video browsing. At the same time, wireless communication technologies are developing rapidly (such as Wi-Fi, 4G, and 5G communicat...
