Algorithm of Developing Lawful Interception’s Systems for Services, Based on Mobile Technology.

      Federal Law "About Communication" operates in Russia. According to this law each telecom services have to be integrated in Lawful Interceptions Systems. Costs of such integration fall to company-operator, which want to implement this service. It means that company-operators have to make technical solutions, realizing lawful interception requirements, and solve problems, appearing during them making. Goal of this article is analyzing technical problems, which have technical specialists engaging in creation, implementation and exploitation technical solutions, realizing lawful interception requirements, and review algorisms of developing Lawful Interception’s Systems for services, based on mobile technology.
Keywords: lawful interception, mobile telecommunication.
