Dynamic sleep method and system for micro base station based on distance and load

Abstract

The invention relates to a dynamic sleep method and system for a micro base station based on distance and load, and belongs to the technical field of wireless communications. The dynamic sleep method comprises the following steps: dynamically adjusting the working modes of base stations according to the distances between the micro base stations and a macro base station and the current load of the system and the current load of the micro base stations; and firstly closing the micro base stations with the distances to the macro base station less than Rth, if the total energy consumption of the system drops and the transmitting power of the macro base station does not reach the maximum transmitting power value, continuing to close the micro base stations with the distances to the macro base station greater than Rth, and stopping closing the micro base stations until the total energy consumption of the system rises or the transmitting power of the macro base station reaches the maximum value. The dynamic sleep method and the system for the micro base station based on the distance and the load provided by the invention can minimize the energy consumption of the system and guarantee the user QoS.

Description

technical field [0001] The invention relates to the technical field of wireless communication, in particular to a method and system for dynamic dormancy of a micro base station based on a combination of distance and load. Background technique [0002] With the introduction of 5G ultra-dense networking, that is, through the dense deployment of small cells within the coverage of traditional cellular networks, the deployment of dense networks has greatly increased the overall network capacity and solved the problem of high-speed user requests in hotspot areas. In dense networking, macro base stations are used to ensure regional coverage, and small cells are deployed in hot spots such as offices, stadiums, or shopping malls, which can not only effectively reduce coverage holes, but also increase system capacity in hot spots. [0003] With the high-speed increase in the number of users and the continuous expansion of the wireless network scale, high-capacity communication network...

Problems solved by technology

This strategy does not consider the load of the base station when shutting down the base station. If the load of the shut down base station is high and the base station is far away from the macro base station (in the edge area), the QoS of these users cannot be guaranteed.
