Embodiment Construction

[0020] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0021] The present invention provides an energy-saving method for dynamically turning on / off micro cells in a 5G network. In this method, by designing a network traffic threshold T L , T H Indicates the lower limit and upper limit of the threshold value; when the traffic load value of the macro cell is higher than the upper limit, the current required network capacity is supplemented by turning on the micro cell, and when the traffic load value is lower than the lower limit, it is improved by turning off some micro cells Network resource utilization, so as to achieve the purpose of energy saving.

[0022] In this embodiment, a two-layer macro-microcell heterogeneous network model is considered. It is suitable for dense network scenarios, such as public places. There are microcells around the macro base station to provide coverage, and th...

Abstract

The invention relates to an energy saving method for dynamically switching on / off microcells in a 5G network, and belongs to the energy saving technical field in a mobile communication network. The method is characterized in that flow threshold values TL and TH of a network are designed to represent a lower limit and an upper limit of the threshold values; and when the flow load value of a macrocell is higher than the upper limit, the microcells are switched on to supplement the network capacity required at present, and when the flow load value is lower than the lower limit, some microcells are switched off to improve the resource utilization rate of the network, so that the purpose of energy saving is achieved. According to the invention, the problem of dynamic microcell energy consumption at a low flow in a heterogeneous network is well solved, and the microcells are switched off to the maximized degree in the set threshold range, so that the energy consumption of the microcells is saved, and the utilization rate of the network resources is improved.

Description

technical field [0001] The invention belongs to the technical field of energy saving in mobile communication networks, and relates to an energy saving method for dynamically opening / closing microcells in a 5G network. Background technique [0002] With the advent of the fifth-generation mobile communication (5G) era, business applications and user experience requirements force network operators to find new technologies to reduce operating costs, increase data transmission rates, and improve user experience quality. The exponential growth of data services makes the demand for network facilities expand rapidly, and also causes a lot of energy consumption. As one of the important requirements of 5G, green energy saving requires that the total energy consumption of the network will not increase when the user data traffic increases by thousands of times. It is estimated that by 2020, the end-to-end energy consumption per bit in the future 5G network will need to be reduced to 1 / ...
