    Ensuring convergence in next-generation wireless networks
    (ХНУРЕ, 2021) Saburova, S. A.; Kukharchuk, М. М.; Kadatskaja, О. I.; Al Masri Omar Mohammad
    Presented сconvergence between 5G and Wi-Fi, wich is happening not only at the technical level, but this convergence is driving all telco industries to the more challenging convergence of IT and Telecom toward integrated Information & Communication Technology (ICT). The analysis showed that traditional voice and data services have prevailed over the past two decades, but now they have reached their ceiling and more vertical services are needed to grow the business. Wi-Fi 6 will not only deliver higher speeds and capacity, but it will enable new business models and use cases independently and also in convergence with Mobile 5G Technology, which is not limited to voice and data offload only but spanning over IT/IoT Convergence.

    Service functions iot of 5g platform
    (ХНУРЕ, 2019) Kadatskaya, O.; Saburova, S. A.; Elмеhdоj, Моhмеd S.
    Researched 5G network platform, which provides operators with significant advantages, expressed primarily in expanding the functionality and performance of the network (performance) and increasing user satisfaction (User Experience). As a result, 5G is a system, or “platform,” which refers to a software platform, not a hardware platform. It is known that 1G / 2G / 3G / 4G networks were built on the basis of hardware solutions (equipment), and the 5G platform is built on the basis of software solutions, with software-configured networks technologies SDN (Software Defined Network), virtualization of network functions NFV (Network Function Virtualization). The 5G network architecture is not based on the classic definition and content, as “network architecture”, which is based on hardware implementation. On the 5G network, it is no longer relevant.

    Support of resourses redistribution in NB-IоT LTE networks
    (ХНУРЕ, 2024) Kadatskaya, O. I.; Saburova, S. A.
    The NB-IoT is expected to be used with the deployed LTE network as well as future 5G networks. The rapid development of the IoT concept has entailed the need to provide wireless communication to a huge number of devices included in the infrastructure. As part of the 5G NR standard for such devices, Massive Machine Communications (m MTC) technology is focused on optimizing the use of network resources to support a large number of stable connections per unit area. The Narrowband Internet of Things (NB-IoT) has been analyzed to enable the connectivity of a wide range of new IoT devices and services to the mobile network. The NB-IoT is also shown to be designed for fixed devices with low data transmission and low consumption, leading to an increase in the number of interconnected devices. In turn, standard NB-IoT modules attempting to simultaneously request radio channel resources for uplink data transmission may suffer from random access preamble collision. The proposed model describes the macro- and microcells of an NB-IoT LTE cluster. An increase in the efficiency of using the bandwidth of networks based on macro- and microcells with a high concentration of users of the NB-IoT LTE networks is shown. Numerical results of an analysis of identifying factors affecting system performance are presented. A linear increase in throughput has been revealed depending on the throughput of the macrocell when using the shared resource of the macrocell for a microcell of equal size without prior repacking of channels when servicing moving subscribers. In the absence of moving subscribers, the additional load is serviced, and the efficiency of using a macro cell increases almost 3 times. In addition, repacking channels significantly increases system throughput. Key words: narrowband; Internet; things; efficiency; macrocells: microcells; resource; model; throughput; repack aging; channel; network.

    The VoIP quality of service over IMS
    (ХНУРЕ, 2019) Kadatskaja, О. I.; Saburova, S. A.; Baha Fesal
    IP Multimedia Subsystem (IMS) has resulted from the work of the 3GPP) toward specifying an all-IP communica-tion service infrastructure. This thesis uses the E-Model developed by ITU-T and for select network and voice pa-rameters like coding scheme, packet loss limitations, and link utilization level in IMS network. Is finded the optimal voice coder given link bandwidth
