Abstract
In the lives of modern people, it is difficult to leave mobile communication technology. With mobile base stations as the guarantee of smooth communication, the maintenance and management of base station equipment is extremely important. How to ensure the network quality of the mobile communication network has become an important part of the communication network. In addition to more and more perfect communication technology and more and more mature communication equipment, mobile base stations have played a fundamental and guaranteeing role in the mobile communication process. This article starts with the maintenance of mobile base stations, discusses the general steps of base station maintenance, and briefly introduces common methods of fault location. It mainly studies the processing methods of base station faults, including the handling of call faults, network faults, and loading. Failure handling, base station alarm failure and other failure analysis and processing, and finally cited examples of base station maintenance.
Key words mobile base station; equipment; fault maintenance; management
