Abstract

The invention belongs to the mobile communication technology field and discloses a multi-target optimization carrier wave migration target base-band pool selection method based on conflict equilibrium. According to the method, after a carrier wave migration signal is received, a migration target base-band pool selection model based on multi-target optimization is established for to-be-migrated carrier waves; an approximation ideal solution algorithm based on a dynamic objective weight value and a conflict equilibrium degree to solve the established selection model, and a migration target base-band pool is selected. The method is advantaged in that conflicts among different optimization targets can be completely eliminated, the proper migration target base-band pool can be selected, maximization of user service quality of migration carrier waves and minimization of base-band pool system power consumption and carrier wave migration energy consumption can be both better realized, and carrier wave migration cost performance is made to be higher.

Description

technical field [0001] The invention belongs to the technical field of mobile communication, and in particular relates to a method for selecting a baseband pool for multi-objective optimized carrier migration based on conflict balance. Background technique [0002] With the development of wireless access networks for mobile communications, wireless access equipment is undergoing an evolution process from traditional integrated base stations to distributed base stations and then to base station resource pools. The distributed base station separates the radio frequency unit from the base station, and puts the distributed base station and the remote antenna together to form a remote radio unit (Remote RadioUnit, RRU), while the original base station cabinet only leaves the baseband unit (BasebandUnit, BBU ). On the one hand, putting the RRU and the antenna together reduces the attenuation of the antenna feeder and can reduce the transmission power of the base station; The con...
