Energy saving method based on heterogeneous honeycomb wireless network and implementation structure thereof

Abstract

The invention discloses an energy saving method based on a heterogeneous honeycomb wireless network and an implementation structure thereof. The method is implemented by dynamically opening and closing a honeycomb cell and comprises the following steps that: (1) a base station of a basic cell determines the state information of an auxiliary cell; (2) the base station of the basic cell judges whether the auxiliary cell is in a sleep state; if so, the step (3) is executed; otherwise, the step (4) is executed; (3) the base station of the basic cell makes cell awake decision; if the load of the basic cell exceeds a system load threshold, the base station of the basic cell sends a cell awake calling instruction to the auxiliary cell so as to activate the auxiliary cell to process a user access request; and (4) a base station of the auxiliary cell makes cell closing decision, selectively closes the auxiliary cell and sends a cell closing instruction to the basic cell to indicate that the auxiliary cell is closed based on the aim of saving the network energy; and the base station of the basic cell processes the user access request.

Description

technical field [0001] The invention relates to a cellular wireless communication network, in particular to a method for reducing network energy consumption in a heterogeneous cellular network using more than two types of base station network layout and its realization structure. Background technique [0002] In recent years, due to the excessive emission of greenhouse gases and the aggravation of global warming, the protection of the ecological environment and the reduction of the negative impact of human activities on the environment have become increasingly severe. Due to the exponential increase in the number of users, the scale of various communication networks is getting larger and larger, and the energy consumption of the information and communication technology industry (ICT industry) accounts for a rapid increase in the proportion of the world's total energy consumption. The ICT industry is gradually developing into High energy consumption industries. At present, t...

Problems solved by technology

[0007] The purpose of the present invention is to provide a method for dynamic switching between the working state and the sleeping state of a cell facing a heterogeneous wireless communication network, so that some cell base stations in the network enter the sleeping state when the communication network load value is low, reducing The energy consumption of the overall heterogeneous wireless communication network, so as to solve the serious energy waste problem caused by the base station still maintaining the working state when there are few or no users in the cellular network
