This article discusses the issue of assessing the survivability of a mobile communication system by analyzing the topologies of the structure of the mobile communication system and algorithms for their functioning. Several ways of ensuring the survivability of the mobile communication system in emergency situations (ES) were considered, and a method was proposed that is more effective in these regions. Opinions were expressed on structured models of cellular networks taking into account ES. Taking into account ES in these regions, installation of base station (BS) is recommended.
