The article examines requirements to point for autonomous access to information in a 4G mobile communications network. It is noted, that the objects of interception are the content of communication sessions of interception subjects (surveillance subscribers), information about their location and service profiles fixed to the end (terminal) equipment of interception subjects. Two groups of requirements are specified: general and specific only for the interception of information in specified network. The authors, like a number of scientists, consider a single system of technical means to be a functional combination of control and processing means of bodies authorized to remove information from electronic communication networks, means of protected transport network and network set. Certain functional modules of the 4G mobile communication networks, interaction with which is necessary for authorized bodies to lawful intercept information, are given. It is established the type and content of the information, that generated by the specified functional modules. It is noted, that actions for simultaneous interception of information must be carried out in automatic mode at the point for autonomous access to information in the mobile network. Attention was drawn to the need to modernize the gateways of network sets of the technical means for their adaptation to use in the 4G mobile communication network. The gateway of the network set of the technical means of the interception system on the internal interfaces must provide to functional modules a surveillance table with identification objects and must receive from them informational messages and metadata of interception objects, related with interception subjects (surveillance subscribers). Suggested offers for changes to the normative document on lawful interception in Ukraine. The proposals are recommended to be used during the planning of operativesearch, counter-intelligence, reconnaissance measures and covert investigative (search) actions in 4G mobile communication networks of public use in Ukraine.
