[0088] The specific implementation method of the present invention will be described in detail below with reference to the accompanying drawings.
[0089] Combining the characteristics of future communication development, the present invention first proposes a research scenario, a D2D communication heterogeneous network with caching hardware devices, where small cell base stations and D2D users in the heterogeneous network have different caching functions, and the cached content can be passed locally The method of communication reduces repeated requests for resources; on the basis of content allocation optimization, the performance of user access selection and resource allocation after access is greatly improved; by optimizing user access selection, the local service of cached content can be maximized , And through a reasonable resource allocation plan, and then achieve system optimization.
[0090] In the D2D heterogeneous network with cache, combining system revenue and overhead,...
