A centralized method for dynamically shutting down base stations for cellular networks

Abstract

The invention discloses a method for intensively and dynamically closing base stations of a cellular network. The method includes the steps as follows: step one, a time period T is divided into N equant time intervals, each time interval is taken as Tin, and the opening and closing states of all base stations in the network are determined with a centralized algorithm according to known network information at the starting moment of each time interval; and step two, the base states in the cellular network keep the opening and closing states determined in the step one unchanged until the next moment when the states of the base stations are determined comes. According to the method, the energy consumption of the whole network is reduced by dynamically closing part of the base stations in the cellular network.

Description

technical field [0001] The invention belongs to the field of cellular networks, and in particular relates to a centralized method for dynamically shutting down base stations in cellular networks, which utilizes the inhomogeneity of traffic in cellular networks (referred to as "networks") in time and space, based on known The entire network information (including channel information and user information, etc.), and dynamically shut down some of the base stations. Background technique [0002] With the rapid growth of people's demand for higher transmission rate and wider area coverage, the existing mobile communication system has evolved into a high energy consumption industry. Statistics show that in 2009, my country's three major telecom operators consumed a total of 28.9 billion kWh of electricity , an increase of more than 25% compared to 2008, equivalent to nearly 10 million tons of standard coal, which not only means huge operating costs, but also brings a lot of carbon ...

AI Technical Summary

Problems solved by technology

[0003] The distribution of traffic in the network in the time domain and air domain is uneven and random. Therefore, in order to ensure that users can obtain satisfactory services at any time and any place, the cellular network usually adopts a static design concept, usually according to the peak traffic of the business and the network The seamless coverage needs to be equipped with base station resources and keep running in this state uninterruptedly, but the peak traffic time of a specific cell is very short, so most of the time the base station is working in a state of low traffic load or even no user access , and the energy consumed by the base station mainly comes from relatively fixed power amplifiers and supporting equipment, accounting for about 70% of the total energy consumption of the base station, that is to say, even if there is no business demand in the cell, the base station will consume a lot of energy, so This needs to be improved from the perspective of network energy consumption
