Keywords: 3GPP specifications, 5G networks, satellite segment, payload, user equipment, base station, satellite gateway, radio access network, core network.
The article considers the main directions of 3GPP work on standardization of joint use of 5G and Non-Terrestrial Networks (NTN), which can include satellites in orbit of different types, high-altitude platforms, drones or other airborne vehicles. The focus of the article is on those sections of the 3GPP specifications, which are related to the specific features of NTNs due to the long signal propagation time in satellite channels, the fast movement of non-geostationary satellites relative to the Earth’s surface, as well as the large size of satellite coverage areas. The first part of the article provides a brief history of 3GPP's work on the integration of NTNs into 5G specifications, describes the types and architecture of NTNs and reviews the methods of signal delay compensation in satellite channels proposed in the 3GPP specifications

Keywords: communication system, unauthorized access, breaking the encryption code, physical layer, channel layer, network layer.
The information security system in modern communication networks assumes the presence of end-to-end control of work at the levels from the physical (L1) to the application level (L7). The article shows the possibilities of significantly simplifying hacking with subsequent access to service and user information of the network, if the work on the physical (L1) and channel (L2) levels is not fully controlled by the network administrator. Moreover, even encryption methods used at the network (L3) and higher levels do not protect against such hacking. By means of uncontrolled influences, conditions are created for the consistent hacking of protection from level to level up, like the «opening of a matryoshka doll». On the other hand, the hacking party’s lack of access to the L1 and L2 levels makes, with certain efforts, the process of unauthorized access to information of the upper levels of modern networks extremely difficult even in cases where there is no encryption on them. These antihacking capabilities are considered using the example of a generalized proprietary broadband access system.

Keywords: nonlinear code multiplexing, phase group sequence, element-by-element reception, energy gain, CDMA.
The paper considers the problem of increasing the noise immunity of multiphase CDMA sequences by reducing the number of phases and the dynamic range. Multiphase CDMA sequences are obtained by summing phase information orthogonal sequences. The reduction in the number of phases and dynamic range is achieved by converting each element of the multiphase CDMA sequence into a phase element of the group sequence with a module selected from possible integer modules. For the group sequences obtained as a result of such a transformation for various numbers of subscribers, using computer simulation, the dependence of the energy gain on the change in the number of phases relative to the transmission of binary information signals is determined.

Keywords: queuing system, main characteristics, golden section.
The analysis of the main numerical, temporal and one of the probabilistic characteristics of the classical single-channe queuing system M/M/1 is carried out, the results of which allow, along with particular conclusions for each analyzed characteristic, to obtain a system-wide pattern in the form of a manifestation of the golden section in direct or indirect form. A stable ratio was obtained between incoming calls (packets) to the buffer and their service by the server, but without denial of service and with the maximum possible service performance. This ratio corresponds to inflection points with coordinates in golden sections, which are the boundaries of the transition between natural numbers and their inverse values (fractions) relative to the unit value of the average queue length in the buffer of the queuing system.

Keywords: high-density 3D IoT network, fractal dimension, network clustering.
The paper presents a model of a high-density 3D network of the Internet of Things, which describes the features of the structure using the fractal dimension of the network. The paper presents an analysis of methods for estimating the fractal dimension of a network and proposes a method for clustering a network based on the method for estimating the fractal dimension. The proposed method can be effective in network clustering organized in multi-storey buildings. It gives a gain in the proportion of clustering errors compared to a number of known methods and can be used in the tasks of building high-density Internet of Things networks.
