Abstract

The methods of choosing controlled parameters to achieve the required level of reliability of checking the state of the telecommunication network, determining their number and control sequence are proposed. The method of evaluating diagnostic parameters in conditions of failure, which provides reduction of errors, is improved. The method is based on the use of combination of estimates for various statistical characteristics. In order to assess the technical condition of the communication channel elements as diagnostic features, it is proposed to use the parameters of failure, useful signals, secondary statistical characteristics. The algorithms of identification of failure, in telecommunication systems are developed. Methods of calculation definition of characteristics of technical means of failures detection, their identification and reliability management algorithms are relatively small in complexity, are simply formalized and algorithmized. This makes it possible to configure the reliability management models and their real-time adaptation to changing network operating conditions. The results of theoretical studies of the troubleshooting systems characteristics are brought to specific analytical expressions, algorithms or functional schemes. Using these results, you can reasonably determine the parameters and structure of troubleshooting systems. Obtained results and recommendations may be used for design of management systems and telecommunication networks of different scale and purpose. In further research it is expedient to develop a flexible troubleshooting algorithm that takes into account the adjustment of the probability of failure of the elements after each search step.

Keywords: telecommunication network, failures diagnostics, reliability management, diagnostic parameters, failures identification.
