This paper will introduce some methods for the automatic close-loop optimization and troubleshooting by using the operation support subsystem (OSS)-controlled automated parameter detection and control for the mitigation of untoward radio and inapt antenna parameter settings in the 4G long-term evolution (LTE) and 3G wideband code division multiple access (W-CDMA) network. This article will propose the methods to eliminate the drudging and tedious physical cell site optimization and the extravagant radio frequency drive tests. The upgraded close-loop system will monitor and mitigate the unseemly cell site parameters for the complete automatic optimization and troubleshooting of the mobile radio network. The proposed close-loop automated control system can reduce the operational expenditures (OPEX) and capital expenditures (CAPEX) of the service provider. The novel features of the upgraded close-loop system make it a suitable candidate for the fully automated self-organizing network (SON) and energy-efficient network. The multiple case studies and the numerical results reveal the advantages of the close-loop control system.
