Energy-saving method and system for base station cluster in closed coverage area

Abstract

The invention discloses an energy-saving method and system for a base station cluster in a closed coverage area, and the method comprises the following steps: dividing base stations covering a relatively closed area into one base station cluster, and planning the base station cluster into a TA area; marking the base station at the entrance of the closed area as an energy-saving main base station;when it is detected that no online user or resident user exists in the base station cluster, all base stations, except the energy-saving main base station, of the base station cluster are notified toenter a dormant state; and when the energy-saving main base station detects that a user accesses, notifying all dormant base stations in the base station cluster to enter a normal working state. According to the invention, the dormancy time of the base station can be accurately controlled, and the situation that an online user calls or cannot be connected to a network due to coverage holes is avoided. Energy-saving dormancy can be carried out based on the base station cluster, and operation is more efficient than that carried out by a single base station. In addition, the method is wider in application range, and can be implemented as long as the coverage area of the base station cluster is relatively independent and closed.

Description

Technical field[0001]The present invention relates to base station energy-saving technology in a mobile communication system, in particular to an energy-saving method and system for a closed coverage area base station cluster.Background technique[0002]In order to meet the faster speed requirements of ordinary consumers, as well as the needs of ultra-large-scale link terminals and ultra-low latency in the industrial field, mobile communication networks are developing toward larger bandwidths and larger antenna arrays. What follows is greater power consumption. According to a certain operator, the energy consumption cost of its 4G network accounts for 25% of the entire network operating cost. Due to the use of larger bandwidth and massive MIMO technology in the 5G system, the energy consumption of BBU and AAU is greatly increased. In a typical configuration of a single site of 1BBU+3AAU, the energy consumption of a 5G base station is 10 times that of a 4G base station.[0003]Therefore,...
