Abstract

The invention discloses a method for optimizing energy efficiency in a mobile communication network. The energy efficiency of the mobile communication network can be maximum mainly by combining and utilizing a fraction programming method, a lagrangian multiplier method and a dichotomy method to calculate and obtain optimal emission power of each user equipment. The method helps to solve the problems hard to solve in the prior art; besides, the method is simple and the result is accurate.

Description

technical field [0001] The invention belongs to the field of network technology in a mobile communication system, and in particular relates to a method for optimizing energy efficiency in a mobile communication network. Background technique [0002] As one of the most important performance indicators in mobile communication network design, spectral efficiency has been extensively studied in the past few decades. However, with the wide application of high-speed data services and the rapid increase of network energy consumption, energy efficiency (EE) has become a new research hotspot in mobile communication networks. Since the optimization problem of EE is a quasi-convex optimization problem, it is difficult to obtain its optimal solution in the prior art. Contents of the invention [0003] Purpose of the invention: The purpose of the present invention is to provide a method for optimizing energy efficiency in a mobile communication network in view of the deficiencies in t...
