The measuring instrument of the study was the questionnaire structured into open-ended and close-ended questions and distributed to the sampled population. The research questions were analysed using simple percentage table. The researchers found that IMT Enugu students use Airtel network and exposed heavily to Airtel television advertisements. The study recommended that advertising messages should both be persuasive and reminder-oriented.

A Study on Scalar Multiplication Parallel Processing for X25519 Decryption of 5G Core Network SIDF Function for mMTC IoT Environment

When 5G telecommunication becomes a standardized and widely used communication medium, it must be implemented in coherence with certain 5G network standards and requirements. One such requirement is a Subscription Concealed Identifier called SUCI. SUCI prevents the exposure of international mobile subscriber identity (IMSI), which was a vulnerability in previous generation mobile telecommunication networks. Unlike IMSI, SUCI is encrypted and transmitted using a symmetric key cryptographic algorithm, to prevent the aforementioned vulnerabilities. However, for the first terminal to be encrypted, it is necessary to exchange a key with the home network, and this key exchange for SUCI encryption is performed through the Elliptic Curve Integrated Encryption Scheme (ECIES) key exchange algorithm, which is a public-key encryption scheme. However, ECIES uses more computing resources compared to a symmetric key cryptographic algorithm. Additionally, for 5G Subscriber Identity Deconcealing Function (SIDF) to satisfy the massive machine-type communication (mMTC) requirements of 5G, it is necessary to decrypt at least a million SUCIs within a short time. This puts a great burden on the 5G home network to provide the mMTC service for IoT. Therefore, in this paper, we propose a method of constructing 5G SIDF in an mMTC IoT environment. A key method of the proposed 5G SIDF configuration is the use of GPUs. This proposal was aimed at reducing the load in the mMTC environment by performing parallel processing of all cryptographic operations performed in the SIDF using a GPU. In particular, we focused on parallelization of public-key encryption algorithms. In addition, we also compared the method proposed in this paper through a survey of various 5G security products.

Ranking of lte cells based on key performance indicators using mcdm methods

The growth in worldwide data traffic and user subscriptions in mobile telecommunication networks makes it increasingly difficult to manage network performance in an environment already containing multiple radio access technologies. Despite the rise of 5G, LTE remains the dominant technology, and new cells are installed daily to support traffic growth and new services such as voice over LTE. Detecting faulty cells in the network is one of the main concerns of operators. Self-organizing networks have been introduced to deal with this problem, and their self-healing function- ality has improved cell fault management. Nonetheless, faulty cell detec- tion remains challenging, and most of the tasks involved are still done manually. This paper introduces a new method of faulty cell detection in an LTE radio access network, applying multiple criteria methods to this problem. The cells are ranked based on selected key performance indica- tors, using the multi-attribute utility theory to construct a utility function. The analytic hierarchy process is used to define weights for the criteria. Keywords: long-term evolution, multiple criteria methods, radio access network perfor- mance management, self-organizing networks.

Antecedents of customer loyalty in mobile telecommunication companies in Cameroon

The mobile telecommunication (telecom) sector has become the basic source of information nowadays, especially in Cameroon. It is used to transfer and deliver information through voice, video, data, graphics, and more at perpetually increasing speeds. The quality of mobile services does not only impact the attraction of new customers but also to maintain the existing ones. The study uses relationship marketing theory and a quantitative and cross-sectional method with 200 respondents. Information was obtained from users of MTN and Orange mobile telecommunication networks. The analyses were done using SPSS version 20. Tangibility, reliability, and assurance dimensions of staff service quality showed a positive relationship with customer loyalty in mobile telecom companies in Cameroon. The findings also highlight the influence of service quality dimensions on customer loyalty in the mobile telecom companies of the country.

Toward pre-standardization of reputation-based trust models beyond 5G

In the last years, the number of connections in mobile telecommunication networks has increased rampantly, and in consequence, the number and type of relationships among entities. Should such interactions are to be profitable, entities will need to rely on each other. Hence, mobile telecommunication networks demand trust and reputation models that allow developing feasible communications in 5G and beyond networks, through which a group of entities can establish chains of services between cross-operators/domains, with security and trustworthiness. One of the key obstacles to achieving generalized connectivity beyond 5G networks is the lack of automatized, efficient, and scalable models for establishing security and trust. In this vein, this article proposes a pre-standardization approach for reputation-based trust models beyond 5G. To this end, we have realized a thorough review of the literature to match trust standardization approaches. An abstract set of requirements and key performance indicators has been extracted, and some pre-standardization recommendations proposed to fulfill essential conditions of future networks and to cover the lack of common trust and reputation models beyond 5G.

Evolutionary approach to secure mobile telecommunication networks

A series of encryption algorithms called A5 is used to secure mobile telephone communications, producing a pseudo-random sequence that will be exclusive OR (XORed) with the data flowing in the air interface in order to secure them. These algorithms are essentially composed of shift registers with linear feedback, controlled generally by a function or with another register in order to favor the randomness character of the keystream generated. Evolutionary algorithms are bioinspired calculation methods, whose principle is inspired by the theory of evolution, which consists in evolving a set of solutions to a problem given in order to find better results. This paper presents an improvement of the A5/1 algorithm by an evolutionary approach based on the use of particle swarm optimization algorithm (PSO) in order to limit some weaknesses and drawbacks found in the conventional A5/1 version, which have been cryptanalysed and several attacks have been published such as time memory trade off attacks and guess and determine attacks. Our technique does not alter the A5/1's architecture, but it does help to improve its shifting system by an evolutionary approach, which guarantees the quality of the keystream generated and makes it more complex and more secure.

Finally a procedure of simulation for coverage predictions and design validation was made. It is concluded that the project is feasible and complies with technical requirements for land survey, services demand on voice and data, coverage for indoor or outdoor environments, mobility and transport users, parameters performance on RSCP, RSRP, RSRQ signal-to-noise ratio, capacity of users, specific scenario solutions and economic benefits on deployments.

The geopolitical hijacking of open networking: the case of Open RAN

This article investigates how discourses on open networking technologies provide a social imaginary that industry and government actors mobilize in an attempt to expand their control over mobile telecommunications networks. The case of recent initiatives aiming to ‘open up’ radio access network (or RAN, a key component of telecommunications infrastructure) with an ‘open RAN’ model reveals how the US Government came to promote this nascent technology to create an opposition between its own ‘open’ telecommunications networks versus proprietary and presumed ‘untrustworthy’ networks based on foreign equipment, namely Huawei. While a closer look casts doubts on the benefits of open radio access network to increase network security or to open up the equipment market, this case reveals how openness is an ambiguous notion that can be used by governments to exclude foreign trade enemies, while advocating for trust in telecommunications networks.

On Supporting UAV Based Services in 5G and Beyond Mobile Systems

While Unmanned Aerial Vehicles (UAVs) are expected to introduce disruptive innovations in our society, it is foreseen that the used communication technology is the key factor that can unlock their potential. To this end, the upcoming generation of mobile networks, 5G-and-beyond, are envisioned to be the communication standards to support diverse UAV applications. This will also enable UAVs to benefit from the limitless progress achieved in mobile systems. To facilitate the support of UAV services in 5G-and-beyond networks, this article introduces a framework that links the mobile telecommunication domain to the UAV domain. The proposed framework reflects an operational view enabling UAV operators to prepare and deploy their applications over different 5G mobile telecommunication networks. Moreover, the framework allows UAV operators to customize mobile systems in accordance with the specifications of their target services and to constantly receive analytical and statistical data on their running applications. Furthermore, in order to ensure network services (dedicated to UAV applications) over heterogeneous mobile systems, this article also discusses the federation of 5G networks.

Data-Driven Methodology for Sustainable Urban Mobility Assessment and Improvement

The transport system is sensitive to external influences generated by various economic, social and environmental changes. The society and the environment are changing extremely fast, resulting in the need for rapid adjustment of the transport system. Traffic system management, especially in urban areas, is a dynamic process, which is why transport planners are in need of a proven and validated methodology for fast and efficient transport data collection, fusion and analytics that will be used in sustainable urban mobility policy creation. The paper presents a development of a methodology in data rich reality that combines traditional and novel data science approach for transport system analysis and planning. The result is overall process consisting of 150 steps from first desktop research to final solution development. It enables urban mobility stakeholders to identify transport problems, analyze the urban mobility situation and to propose dedicated measures for sustainable urban mobility strengthening. The methodology is based on a big data research and analysis on anonymized big data sets originating from mobile telecommunication network, where the extraction of mobility data from the big dataset is the most innovative part of the proposed process. The extracted mobility data were validated through a “conventional” field research. The methodology was, for additional testing, applied in a pilot study, performed in the City of Rijeka in Croatia. It resulted in a set of alternative measures for modal shift from passenger cars to sustainable mobility modes, that were validated by the local public and urban mobility stakeholders.

Denotational semantics of channel mobility in UTP-CSP

In this paper, we present the denotational semantics for channelmobility in the Unifying Theories of Programming (UTP) semanticsframework. The basis for the model is the UTP theory of reactiveprocesses, precisely, the UTP semantics for Communicating SequentialProcesses (CSP), which is extended to allow the mobility ofchannels—the set of channels that a process can use forcommunication (its interface), originally static or constant (setduring the process's definition), is now made dynamic or variable:it can change during the process's execution. A channel is thusmoved around by communicating it via other channels and thenallowing the receiving process to extend its interface with thereceived channel. We introduce a new concept, the capability of a process, which allows separating the ownership of channels fromthe knowledge of their existence. Mobile processes are then definedas having a static capability and a dynamic interface. Operations ofa mobile telecommunications network, e.g., handover, load balancing,are used to illustrate the semantics. We redefine CSP operators andin particular provide the first semantics for the renaming andhiding operators in the context of channel mobility.

Testing the Moderating Effect of Gender on Job Satisfaction and Employees’ Behaviours Relationship: Evidence from Mobile Telecommunication Network (MTN) Buea, Cameroon

With the quest of personalization of actions from their employees, organisations are constantly looking for means that allow them to consider all employees’ needs in designing satisfaction tools that will enable their employees to portray adequate behaviours at work. The present study explored whether gender moderates the relationship between job satisfaction and employees’ behaviours within a telecommunication company in Cameroon (MTN, Buea). A quantitative cross-sectional method was used with a sample size of 212 respondents. The hierarchical moderated regression and the multigroups regression approach were used as data analysis tools. Findings showed that gender moderates the effect of job satisfaction on employees’ commitment and employees’ citizenship behaviour. It is a quasi-moderation and the size effect is characterized as low. Contrariwise, gender does not moderate the effect of job satisfaction on employees’ intention to quit. These findings can help inform intervention efforts by identifying gender-fit job satisfaction tools and policies to optimize the adoption by each group of adequate behaviours in the company.

Koncentracija ponude na odabranim tržištima sektora elektronskih komunikacija Srbije

The electronic communications sector is very important sector of a national economy. It provides an opportunity for facilitating business activities and it is a good area for investment. A small number of operators and a large number of users operate in most markets of the electronic communications sector. The conditions under which electronic communications services are available to users in different countries diverge, among other things, due to the degree of liberalization of individual markets in these countries. The Republic of Serbia has significantly liberalized this sector of economic activity by adjusting it according to the regulations of the European Union. However, certain entry barriers have remained, primarily related to the licenses that operators need to obtain to operate in the Serbian market. The paper aims to investigate the level of concentration in selected markets of the electronic communications sector, namely: mobile telecommunication networks and services, broadband Internet services and media content distribution. The research showed a high level of concentration measured by the Herfindahl-Hirschman index in all three markets. A further increase in concentration is expected in all analyzed markets in the short term. These research results require more attention from regulatory bodies because they increase the possibility of some form of non-competitive behaviour by undertakings.

Understanding Why People Change Their Technology Use in Protests: User Study on Ebonyi State Mobile Telecommunication Subscribers Experiences

The rise in consumers complains against their service/tech providers has empowered government of various nations to set up Consumer Complaint Commissions. Some corporate organizations who wish to handle the complaints of their customers usually set up an in-house/internal customer care centres, a platform through which they attend to their customers’ needs. This research therefore is interested in exploring the reasons for user-protests among the mobile telecommunication subscribers in Ebonyi State, Nigeria against their network service providers. To arrive at this, we designed a research questionnaire to capture the experiences of the subscribers of the 4 major mobile telecommunication network service provider companies operating in the state. The participants were recruited through physical administration of research instrument and social media such as facebook, whatsapp and email platforms with a total of 72 participants feedbacks received. The users responses on the various issues raised on our questionnaire were thematically analyzed and represented using adequate data presentation tools. Our results proved that there are growing numbers of disgruntled customers among subscribers of the various network providers. From our survey, we gathered that 81.90% of the respondents have engaged in protest use at one point or the other against their service providers with MTN network topping the list with 36.50%, followed by GLO network 27%, Airtel network 23.80% and 9 Mobile 12.70%. Finally, we proposed a design prototype named “Komplain” that will serve as rallying system for the protest users to use and prosecute their actions. The system can also recommend actions which the protesters may undertake.

Performance Analysis of WOFDM‐WiMAX Integrating Diverse Wavelets for 5G Applications

In the 5th generation (5G) and 6th generation (6G) of wireless mobile telecommunication networks, the requests for an elevated data rate with access to stationary as well as portable customers are going to be overwhelming. Mobile worldwide interoperability for microwave access (WiMAX) comes out as a favourable alternative that is intelligibly developed and more matured than wireless fidelity (Wi‐Fi). Mobile WiMAX makes use of the orthogonal frequency division multiple access (OFDMA) technology for its two‐way communication to enhance the system performance in fading environments making it more suitable for 5G applications. The diverse OFDM forms deliberated here are the fast Fourier transform‐ (FFT‐) based WiMAX and discrete wavelet transform‐ (DWT‐) based WiMAX. The suggested study exhibits the bit error rate (BER) and peak to average power ratio (PAPR) reduction by integrating different wavelet families, i.e., Haar, symlet, coiflet, and reverse biorthogonal over Rayleigh fading channel. The simulation results obtained by MATLAB depicts an improvement in PAPR reduction, and signal to noise ratio (SNR) requirement is also reduced by 6‐12 dB by using DWT‐incorporated WiMAX at a BER of 10-4.
