“…For instance, a Network Exposure Function (NEF) would make it possible to expose network parameters to third-party applications or, together with information from a near-RT RIC, be used to configure the network using AI/ML techniques, for instance, in a non-RT RIC. Another option would be to include a Location Management Function (LMF) in a similar way as in [13] so that researchers could explore different UE-based and UE-assisted 5G positioning techniques.…”

“…This is one of few publications that take advantage of the opportunity open source platforms give to experiment and tune the networks. A Localisation Management Function (LMF) is implemented in [13] using OAI. 5G Non-terrestrial networks (NTNs) are the topic in [14], where an OAI 5G SA platform is used to communicate via a geostationary satellite.…”

Fifth-generation (5G) mobile communication systems are currently implemented worldwide. Moreover, the diversity between different deployments is growing, from operator-deployed macro networks to local private networks. The 5G system is very flexible with a large number of parameters and configurations impacting platform performance. With the availability of private spectrum and open-source software, there is an increasing possibility to get insight into what performance can be achieved in different dimensions, and how it depends on the configuration of various parameters, through experiments and testing. This paper presents a detailed account of a 5G Standalone (SA) platform based on the open5GS and srsRAN software suites installed on a general-purpose workstation. The performance of the platform is measured and compared to theoretical results and information from the 3GPP standardisation documentation. While some aspects of the performance are close to the theoretical expectations, others are further away. The softwaredefined radio (SDR) platform and the lack of hardware acceleration are probably the main limiting factors on coverage, uplink throughput and latency. The paper goes through several radio parameters and their impact on performance and discusses the performance implications and limitations of the experimental platform to share the lessons learned.

“…It offers 5G's more rapid data transfer rates, enabling more efficient security patch management compared to slower network technologies. In the papers [30][31][32], the authors offer 5G network functions and characterize the performance of location management functions in 5G core networks. Security patch management provides better distribution of security patches, reducing exposure to known vulnerabilities and enhancing the network's overall security while working with the mentioned functions.…”

It is clear that 5G networks have already become integral to our present. However, a significant issue lies in the fact that current 5G communication systems are incapable of fully ensuring the required quality of service and the security of transmitted data, especially in government networks that operate in the context of the Internet of Things, hostilities, hybrid warfare, and cyberwarfare. The use of 5G extends to critical infrastructure operators and special users such as law enforcement, governments, and the military. Adapting modern cellular networks to meet the specific needs of these special users is not only feasible but also necessary. In doing so, these networks must meet additional stringent requirements for reliability, performance, and, most importantly, data security. This scientific paper is dedicated to addressing the challenges associated with ensuring cybersecurity in this context. To effectively improve or ensure a sufficient level of cybersecurity, it is essential to measure the primary indicators of the effectiveness of the security system. At the moment, there are no comprehensive lists of these key indicators that require priority monitoring. Therefore, this article first analyzed the existing similar indicators and presented a list of them, which will make it possible to continuously monitor the state of cybersecurity systems of 5G cellular networks with the aim of using them for groups of special users. Based on this list of cybersecurity KPIs, as a result, this article presents a model to identify and evaluate these indicators. To develop this model, we comprehensively analyzed potential groups of performance indicators, selected the most relevant ones, and introduced a mathematical framework for their quantitative assessment. Furthermore, as part of our research efforts, we proposed enhancements to the core of the 4G/5G network. These enhancements enable data collection and statistical analysis through specialized sensors and existing servers, contributing to improved cybersecurity within these networks. Thus, the approach proposed in the article opens up an opportunity for continuous monitoring and, accordingly, improving the performance indicators of cybersecurity systems, which in turn makes it possible to use them for the maintenance of critical infrastructure and other users whose service presents increased requirements for cybersecurity systems.
