The Methodology for Synthesizing the Parameters of the Cellular Communication System Maintenance Strategy

The methodology of assessing the functional safety and availability indexes of the cellular communication system, taking into account not only the reliability of its components, but also the parameters of its maintenance strategy is presented in the article. The correct choice of maintenance parameters of the cellular communication system will reduce the frequency of emergency and ensure a given coefficient of readiness during operation. The methodology is based on a stochastic model of operational behavior of cellular base stations. This technique will be useful both for the stage of system design of the cellular communication system and for the stage of its operation. Thus, at the stage of system design, the methodology allows for a given value of its functional safety, to determine acceptable to the designer values of reliability and parameters of maintenance strategy. At the stage of operation - the methodology allows to determine the required values of the parameters of the maintenance strategy for a cellular base station with a known value of its functional safety, which should provide the repair service of the communications company.
