Résumé :

Development of high-speed railways set up challenges for new communication technologies. With the increase in speed, new requirements for communication systems have emerged that HSR requires greater reliability, capacity and shorter response time for efficient and safe operations. Mobile communication systems are crucial for the competitiveness of the railway industry and therefore have become one of the priorities addressed by the participants in the railway system to take advantage of technological opportunities to improve operational processes and the quality of provided transport services. The European Rail Traffic Management System (ERTMS) uses the Global System for Mobile Communications for Railways (GSM-R) for voice and data communication to communicate between trains and control centers. The International Railway Union is exploring new ways of communicating for high-speed railways because as speed increases this system becomes unreliable in information transmission. This paperwork presents an analysis of the evolution of communications on European railways since the usage of GSM-R. In addition, an overview of the various alternative solutions proposed during the time (LTE-R, Future Railway Mobile Communication System) as possible successors to GSM-R technology is given.

Résumé :

With the development of mobile communication technologies, people can now engage in seamless communications with family members and coworkers at both home and work. When promoting a new mobile communication technology (e.g., the 5G network), firms may be tempted to emphasize how the technology can strengthen communication both within and across the two domains with the hope of improving purchase rates. Yet research has suggested that people may perceive mobile communication differently depending on whether those they are communicating with others who belong to the same domain. Thus, the promotion of the technology to potential users should perhaps consider users’ location domain and their communication targets. Through a field experiment, we show that when promoting mobile communication technology in the home domain, highlighting prevention-focused communication promotes greater purchase rates. However, at work, when coworkers are the target of communication, highlighting promotion-focused communication works better. These findings can not only help practitioners design more effective promotional messages in promoting mobile communication technologies but also contribute to the understanding of nuanced differences in the nature of mobile communication that make it more appealing to users in different within- and cross-domain communication scenarios.

Résumé :

With the rapid development of mobile internet, more and more frequency band will be needed to meet the requirement of high data speed. The system coexistence between mobile system and broadcast system is studied, including the scenarios, models, simulation results, related analysis, and finally the solution to resolve the coexistence is given. In urban, an additional 37dB isolation between broadcast system and mobile base station should been satisfied. And an additional 15.7dB is needed between mobile base station and broadcast receiver.

Résumé :

In today's increasingly connected world, the demand for secure mobile communications is paramount. The security protocols are specifically tailored for mobile communication systems, ensuring the confidentiality and integrity of sensitive data transmitted over wireless networks. It can be seamlessly integrated into various mobile applications such as messaging platforms, VoIP services, and mobile banking apps, providing end-to-end encryption for user privacy. Current encryption protocols used in mobile communications often face challenges related to performance and security. Traditional encryption methods may not adequately address the evolving threats posed by sophisticated attackers. Moreover, the computational overhead associated with encryption and decryption processes can impact the overall efficiency of mobile communication systems. This work presents a novel approach to enhancing the security of mobile communications through the design of a Pipelined Advanced Encryption Based Cryptography Protocol (PAEBCP). The proposed protocol aims to address the vulnerabilities present in existing encryption methods by leveraging a pipelined architecture for efficient encryption and decryption processes. The proposed PAEBCP protocol introduces a pipelined architecture that optimizes the encryption and decryption processes for mobile communication systems. By dividing the encryption process into multiple stages and parallelizing key operations, the protocol enhances both security and performance.

Résumé :

The creation and operation of mobile communication systems is impossible without determining the parameters of base stations and mobile communication systems. For these purposes, appropriate devices are used that optimally combine testing capabilities in a single portable solution, which eliminates the need for several separate control and measuring devices. One of the main types of measurements of such devices is the measurement of the power of ultra-high and extremely high frequency signals. The article presents the method of calibrating meters of directional and absorbed power of ultra-high and extremely high frequency signals using the Bird 5000-EX mobile communication system parameter analyzers complete with the Power Sensor 5010V sensor and measuring sensors, Anritsu CellMaster MT8212EA and Arnitsu SiteMaster S331E spectrum analyzers. Calibration schemes for analyzers of parameters of mobile communication systems and analyzers of mobile communication base stations (hereinafter referred to as analyzers) have been developed. A measurement model of the analyzers based on the parameters of the directional and absorbed power of ultra-high and extremely high frequency signals based on the developed calibration schemes was created. The contribution of each component of the measurement model to the calibration result and the corresponding uncertainties of the model components were determined. The measurement uncertainty budget was made based on the proposed analyzer calibration model. The influence of the most significant influential values on the accuracy of measurement results was analyzed. The content of quantitative and qualitative indicators of corrections, which must be taken into account during calibration to achieve the highest accuracy of measurements, is revealed. The practical results of studies of measurement instability are given. The analyzer calibration method described in the article can be used in calibration laboratories that have the appropriate equipment and standards.

Purpose The purpose of this paper is to develop a research model examining users’ perceived needs-technology fit of mobile communication software through motivational needs and technological characteristics. The study investigated the effects of perceived needs-technology fit on user satisfaction and intention to continue using mobile communication software. Design/methodology/approach This study proposes a research model based on task-technology fit theory and uses and gratification theory, incorporating key determinants of users’ continuance intention toward mobile communication software. An online survey instrument was developed to collect data, and 403 questionnaires were used to test the relationships in the proposed model. Findings The causal model was validated using AMOS 21.0, and all nine study hypotheses were supported. The results indicated that users’ perceived needs-technology fit and satisfaction were crucial antecedents of their intention to continue using mobile communication software and that they mediated the influence of users’ needs as well as technological characteristics. Practical implications Mobile communication software practitioners should focus on enhancing users’ perceived needs-technology fit through motivational needs (utilitarian, hedonic, and social needs) and technological characteristics (mobile convenience, service compatibility, and user control) to further boost user satisfaction and intention to continue using mobile communication software services. Originality/value This study contributes to a theoretical understanding of factors explaining users’ continuance intention toward mobile communication software.

Résumé :

The current mobile network core is built based on a centralized architecture, including the S-GW and P-GW entities to serve as mobility anchors. Nevertheless, this architecture causes non-optimal routing and latency for control messages. In contrast, the fifth generation (5G) network will redesign the network service architecture to improve changeover management and deliver clients a better Quality-of-Experience (QoE). To enhance the design of the existing network, a distributed 5G core architecture is introduced in this study. The control and data planes are distinct, and the core network also combines IP functionality anchored in a multi-session gateway design. We also suggest a control node that will fully implement the control plane and result in a flat network design. Its architecture, therefore, improves data delivery, mobility, and attachment speed. The performance of the proposed architecture is validated by improved NS3 simulation to run several simulations, including attachment and inter- and intra-handover. According to experimental data, the suggested network is superior in terms of initial attachment, network delay, and changeover management.

Abstract. Next generation wireless communication systems will consist of a large number of mobile or static terminals and should be able to fulfill multiple requirements depending on the current situation. Low latency and high packet success transmission rates should be mentioned in this context and can be summarized as ultra-reliable communications (URC). Especially for domains like mobile gaming, mobile video services but also for security relevant scenarios like traffic safety, traffic control systems and emergency management URC will be more and more required to guarantee a working communication between the terminals all the time.

Mobile communications systems such as cellular radios have recently become very widespread and important to both business and personal users. A key component in the radio transceiver is an antenna duplexer, which makes it possible to use a single antenna to transmit and receive RF signals simultaneously. In this chapter, block diagrams of radio transceivers are shown and the frequency characteristics required for duplexers are discussed with regard to the system requirements. Procedures for designing duplexers using SAW-resonator-coupled filters and experimental results relevant to several systems are presented. Non-linear characteristics of the duplexers are also discussed.

Modern mobile stations do not have the capability to overcome marshy areas, steppe, heavily rugged reliefs of the desert, water barriers and forests. Moreover, the coverage area from one base station is not highly localized (radio coverage area is not significant). Furthermore, modern mobile communication facilities have poor autonomy. The article proposes measures for an operational organization of cellular communications in large remote areas with a coverage radius of a medium-sized city. Article also considers the issues posed by a temporary organization of communication service in large sections near important locations (pipelines, riverbeds, transport and railway lines). The need for such an operational usage of mobile communication systems is most associated with geological exploration and scientific research in large remote areas and large areas with a damaged communication system due to natural emergencies or military operations.

Résumé :

Развитие морских интеллектуальных систем и их телекоммуникационного оборудования в ближайшее время будет происходить в условиях обострения проблем, связанных с: ростом уровня помех; повышенных требований к удельной пропускной способности; ограничений на ресурсы связи, сокращение допустимого времени реакции на изменение условий среды связи и взаимодействия носителей телекоммуникационного оборудования в ближней зоне. В работе предлагается новый способ мобильной связи, учитывающий перечисленные факторы. Целью работы является сокращение времени реакции радиосети на изменение условий при выполнении хэндовера и роуминга. Задача предусматривает анализ технологий подвижной радиосвязи. Вопрос развития особенно остро стоит для морского транспорта в условиях интенсивного движения в проливах, когда требуется интеллектуальный помощник в выработке вариантов управленческого решения во взаимодействии по технологии V2X. Статья посвящена поиску направлений по совершенствованию мобильной связи на морском транспорте. Актуальность связана с возрастанием скоростей носителей абонентов, интенсивности движения и отсутствием новых потенциальных возможностей по наращиванию пропускной способности телекоммуникационных систем. Метод решения поставленных задач основан на анализе развития и прогнозировании требований к мобильной радиосвязи. Новизна заключается в построении инициатором виртуальной мобильной сети, собираемой из доступных радиосистем связи на время решаемой задачи. Основные выводы: достигнут новый технический результат - сокращение времени реакции радиосети на изменение условий и ограничений работы мобильной радиосвязи. The development of marine intelligent systems and their telecommunications equipment in the near future will occur in the conditions of aggravation of problems associated with: the growth of the level of interference; increased requirements for specific throughput; restrictions on communication resources, reduction of the permissible reaction time to changes in the conditions of the communication environment and the interaction of telecommunication equipment carriers in the near zone. The paper proposes a new method of mobile communication, taking into account the listed factors. The aim of the work is to reduce the reaction time of the radio network to changes in conditions when performing handling and roaming. The task involves the analysis of known mobile radio communication technologies. The issue of development is especially acute for maritime transport in conditions of heavy traffic in the straits, when an intelligent assistant is required in the development of management solution options in interaction with V2X technology with available facilities and infrastructure. The article is devoted to the search for directions for improving mobile communication in maritime transport. The relevance is associated with an increase in the speed of subscriber carriers, traffic intensity and the lack of new potential opportunities to increase the capacity of telecommunication systems.

The method of solving the tasks is based on the analysis of the development and forecasting of requirements for mobile radio communication. The novelty lies in the construction by the initiator of a virtual mobile network assembled from available radio communication systems at the time of the task being solved. The main conclusions A new technical result has been achieved - reduction of the reaction time of the radio network to changes in the conditions and restrictions of mobile radio communication.
