Base station cooperation dormancy method and system applied to cellular heterogeneous network

Abstract

The embodiment of the invention provides a base station cooperation dormancy method and system applied to a cellular heterogeneous network. The method includes the steps of obtaining the current available green energy amount, user groups capable of conducting serving, and current user information of users capable of being served in the user groups capable of conducting serving with any time period, wherein the available green energy amount, the user groups capable of conducting serving and the current user information are determined through all base stations at a preset time point of the current time period; determining a service set which all the users capable of being served belong to according to the comparison result of the current allowable time delay in the current user information and the preset time delay threshold value; determining the cooperation dormancy mode of all the base stations in the next time period and noticing all the base stations to conduct cooperation dormancy according to the current available green energy amount, the current channel gain from the base stations to the users capable of being served in the current user information, the service set which the users capable of being served belong to, the user groups which correspond to the base stations and can conduct serving, the current to-be-processed service amount and processing rules which the preset coordination dormancy method based on.

Description

Technical field [0001] The present invention relates to the field of communication technology, in particular to a base station cooperative sleep method and system applied to a cellular heterogeneous network. Background technique [0002] In recent years, with the rapid application of wireless networks and smart phone technologies, high data rate services have become more and more popular among users, and the development of innovative communication technologies has also promoted the use of communication resources. However, at the same time, information communication The technology industry has also become one of the main sources of global energy consumption and greenhouse gas emissions. With the introduction of the concept of green communication, more and more attention has been paid to the energy efficiency of the network, and energy conservation, emission reduction, and reduction of energy consumption have become current research hotspots in the communications industry. [0003] ...

AI Technical Summary

Problems solved by technology

[0004] In the prior art, most of the research work on cooperative dormancy of base stations only focuses on the cooperation of base stations based on traditional energy sources, without considering the use of base stations based on green energy and the impact of energy constraints on cooperative dormancy, and, regarding the consideration of real-time There is little discussion on the research of green base station cooperative dormancy when the business characteristics of real-time / non-real-time business (that is, user business requirements)
