NETWORK ENERGY EFFICIENCY OPTIMIZATION METHOD AND DEVICE

摘要

Provided are a network energy efficiency optimization method and device. The method comprises the following steps: a macro base station determining an initial network energy efficiency of a cell to be optimized; the macro base station successively calculating a first network energy efficiency of the cell to be optimized corresponding to each low-power base station in a working state after making each low-power base station in a working state in the cell to be optimized be dormant (S302); the macro base station successively estimating a second network energy efficiency of the cell to be optimized corresponding to each low-power base station in a dormant state after waking up each low-power base station in a dormant state in the cell to be optimized (S303); the macro base station determining a base station to be dormant and a base station to be woken up in the cell to be optimized, wherein the first network energy efficiency corresponding to the base station to be dormant is greater than the initial network energy efficiency, and the second network energy efficiency corresponding to the base station to be woken up is greater than the initial network energy efficiency; and the macro base station informing the base station to be dormant of dormancy and the base station to be woken up of waking up.
