nt to work properly, ensure that the signal coverage of mobile munication works, the need for various repeater equipment to effectively monitor and to the remote location of repeater devices are usually widely distributed, their regular site maintenance is very a remote centralized monitoring platform for the repeater could be established, the work management staff would not need to run around, and could manage repeaters fortably. It would be a promotion for repeater management capability. In this context, on the current status repeater monitoring technology, structure and function of the demand for a typical repeater monitoring system is analyzed, introduced under the current conditions of relatively mature technology model, and then design a set based on short Repeater monitoring and management platform messaging technology, to achieve the different manufacturers, different types of repeater centralized monitoring and management. Point to point and repeater short message munications, regular polling, remote configuration, fault alarms repeater monitoring business logic.
