Abstract

The article deals with topical aspects of lawful interception of information in electronic communication networks of mobile communications which simultaneously use the technologies of the fourth (4G) and fifth (5G) generations, as well as IP multimedia communication IMS. Particular attention is paid to the issues of adaptation of technical means and gateways of mobile networks to the use of these technologies, which allows ensuring the smooth operation of operational and investigative measures. The study identifies a list of key functional modules involved in the process of lawful interception of information, including IMS modules, EPC cores based on 4G technology and 5GC cores based on 5G technology. It is noted that these modules generate specific types of information which are necessary to ensure the interception process, in particular, data on subscribers' communication sessions, information about their location, as well as service data IRI (intercept related information) and communication content CC (communication content), which includes voice and other IP sessions. It is established that there is a need to modernize technical means to ensure their compliance with modern requirements and standards, in particular, taking into account the simultaneous use of 4G, 5G and IMS technologies. An overview of regulations and international standards, such as 3GPP and ETSI, regulating the requirements for technical means for the lawful interception of information is provided. It is also emphasized that further research is needed to determine more precise specifications of the information generated by functional modules of networks and its effective use in the interception process.
The article also analyzes in detail the role of international standards, in particular 3GPP and ETSI, in the process of lawful interception of information used in fourth- and fifth-generation electronic communication networks. The author emphasizes the importance of correct identification of IRI service data and CC communication content transmitted through technical means gateways. The author considers the prospects for modernization of network elements and technical gateways, taking into account the future expansion of mobile networks, as well as the need for further improvement of regulatory documents to ensure efficient and safe operation of domestic mobile operators in the context of integration of the latest technologies.

Keywords: lawful interception, electronic communication network, identification features, mobile communication, technical means.
