A communication signal transmission management method of a base station using a computing device configures a distance table for recording remote base stations proximate the base station and a distance between the base station and each of the remote base stations, and stores the distance table in a storage system of the computing device. When the base receives a communication signal from communication device, the method determines a remote base station to receive the communication signal according to the distance between the base station and each of the scanned remote base stations and a current load of each remote base station, and transmits the communication signal to the determined remote base station.
