Methods for Providing Resilience from Electric Power Side to Communications Network Side

Building resilient infrastructure is a Sustainable Development Goal (SDG) defined by the United Nations. Telecommunications infrastructure and electric power infrastructure are crucial to social and economic activities, and increased resilience is required by society. The telecommunications infrastructure requires support from the electric power infrastructure, and vice versa. This dependency limits the degree of optimal control that can be achieved using only the information from one infrastructure. Telecom carriers cannot monitor the status of the electric power infrastructure, which may affect telecommunications' reliability. This problem can be addressed through infrastructure crossover, thus integrating network infrastructure information and electric power infrastructure information. This paper proposes two methods to achieve crossover. The first estimates blackouts of telecommunications service buildings using logs of telecommunications network equipment, even when the power monitoring networks (NWs) have failed. The other prevents construction errors of telecommunications network equipment by detecting changes in the electric current of the equipment. The coordinated use of information from both infrastructures will create new value.
