The Use of Licensing to Promote Competition among Telecom Operators and the Growth of Mobile Telecommunication Networks in Nigeria, 2011-2022

Many practitioners and investors have praised the use of licensing to enhance competition in the telecom sector due to its real effects on the Nigerian economy. However, since 2011, subscribers in the industry have had a mixed experience with the license issue due to problems with telecom companies' exploitative tendencies and antics, which make it difficult for customers to acquire reliable and reasonably priced telecoms services. With a focus on the institutional and legal safeguards put in place by the government to ensure that the operators abide by the licensing and regulation powers granted to them by the law, the study essentially examines how licensing affects competition among telecom operators and the expansion of mobile telecom networks in Nigeria. The paper's methodology adopted the documentary approach, and the data were ostensibly gathered from secondary sources and examined in terms of substance. Neo-liberal theory of the state provided a sufficient theoretical foundation for the examination of the study. The paper's findings demonstrate that while the expansion of Nigeria's mobile telecom networks is aided by the use of licensing to promote competition among telecom operators, consumers' access to affordable and high-quality telecommunications services is restricted by the exploitative tendencies and antics of telecom companies. The paper's suggestions were based on these findings, and one of them was that Telecommunications service tariffs must always be cost-oriented and reflect the actual costs borne by operators to provide the services in question.

ОГЛЯД МЕХАНІЗМІВ ROOT CAUSE АНАЛІЗУ ТЕЛЕКОМУНІКАЦІЙНИХ МЕРЕЖ

Telecommunication networks are an integral part of modern information society, providing data transmission and communication among millions of users worldwide. The complexity and scale of these networks are constantly growing, which increases the demands on their reliability and stability. One of the key tasks in ensuring the efficient operation of telecommunication networks is the identification and elimination of the root causes of failures and anomalies that can significantly affect the quality of service for end users. Root cause analysis (RCA) is a powerful tool for identifying the primary causes of problems, preventing their recurrence, and enhancing the overall reliability of networks. The article provides a detailed review of contemporary methods and tools of RCA used in telecommunication networks. In particular, methods such as fishbone diagram analysis, the «five whys» method, fault tree analysis, and the application of machine learning for big data analysis are considered. Each of these approaches has its advantages and disadvantages, and their comprehensive use allows for higher accuracy and efficiency in identifying the root causes of problems. Practical examples demonstrate the effectiveness of applying various RCA methods to solve specific problems in telecommunication networks. For instance, the use of fishbone diagram analysis and the «five whys» method allows for the identification of the primary causes of network delays and equipment issues at base stations. The implementation of failure prediction systems based on machine learning significantly enhances network reliability by allowing for the early detection of potential problems and the necessary technical measures. The prospects for the development of RCA in telecommunication networks are outlined. The primary focus is on the development of adaptive and self-learning systems capable of dynamically responding to changing network conditions. The use of more complex artificial intelligence algorithms and tools for predicting potential problems will significantly improve the effectiveness of RCA and ensure high-quality telecommunication services.

Research on the application of advertising communication information system based on mobile Internet

With the steady development of intelligent terminal equipment and wireless access network, the Internet has gradually changed from fixed to mobile, which not only creates a mobile Internet platform, but also changes the traditional single mode of information transmission. Through the use of mobile wireless communication to obtain business and services, the mobile communication and Internet platform fully combined, can simultaneously provide network users with images, data, multimedia and other high-quality telecommunications services. On the basis of understanding the current situation of mobile Internet research and application, according to the influence brought by the development of mobile Internet era, this paper deeply studies the mobile Internet as the core advertising communication system, and from the perspective of long-term development of the industry, put forward the application measures of advertising communication information system in the new era.

STEP: A Spatio-Temporal Fine-Granular User Traffic Prediction System for Cellular Networks

While traffic modeling and prediction are at the heart of providing high-quality telecommunication services in cellular networks and attract much attention, they have been approved as an extremely challenging task. Due to the diverse network demand of Internet-based apps, the cellular traffic from an individual user can have a wide dynamic range. Most existing methods, on the other hand, model traffic patterns as probabilistic distributions or stochastic processes and impose stringent assumptions over these models. Such assumptions may be beneficial at providing closed-form formula in evaluating prediction performances, but fall short for practice use. In this paper we propose STEP, a <underline xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink"><b>s</b></u> patio- <underline xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink"><b>te</b></u> mporal fine-granular user traffic <underline xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink"><b>p</b></u> rediction mechanism for cellular networks. A deep graph convolution network, called GCGRN, is constructed. It is a novel combination of the graph convolution network (GCN) and gated recurrent units (GRU), which exploits graph neural network to learn an efficient spatio-temporal model from a user’s massive dataset for traffic prediction. The prototype of STEP has been implemented. Extensive experimental results demonstrate that our model outperforms the state-of-the-art time-series based approaches. Besides, STEP merely incurs mild energy consumption, communication overhead and system resource occupancy to mobile devices. Moreover, NS-3 based simulations validate the efficacy of STEP in reducing session dropping ratio in cellular networks.

Seamless Handover for High-Speed Trains Using Femtocell-Based Multiple Egress Network Interfaces

High-speed rail systems are becoming increasingly popular among long-distance travelers. With the explosive growth in the number of mobile devices, the provision of high-quality telecommunication and Internet access services on high-speed trains is now a pressing problem. Network mobility (NEMO) has been proposed to enable a large number of mobile devices on a vehicle to access the Internet; however, several issues must be solved before it can be put into practice, e.g., frequent handovers, long handover latency, and poor quality of service. To resolve these problems, we propose an LTE femtocell-based network mobility scheme that uses multiple egress network interfaces to support seamless handover for high-speed rail systems called MEN-NEMO. The results of simulations show that the proposed MEN-NEMO scheme reduces the handover latency and transmission overhead of handover signaling substantially.

Public Policy and the Regulatory Environment in Mexico and the World: Bridging the Digital Divide?

The present study examines public policy intended to ensure communications service provision to low-income populations in Mexico. The study takes as its starting point the distinction made in the literature between a “market efficiency gap” and an actual “access gap”. Regarding the former, we posit that failures in regulation occur as a result of a weak institutional framework and a marked imbalance of power between the regulatory authorities and operators from the market-dominant conglomerate comprising Telmex, with 78.4% of landlines, and Telcel, with 67.1% of mobile lines.Difficulties in attempting to regulate these operators have meant a limited ability to remove barriers to entry into these markets and to counter the anti-competitive practices in which the operators engage. The latter behaviour has impeded new operators by raising costs, not least those relating to risk and uncertainty, in the absence of a fair playing field.A recent study found that the lack of competition among telecommunications providers in Mexico has imposed significant costs on the Mexican economy and increased burdened the welfare of the country’s population. It has resulted in low market penetration rates and poor infrastructure development. The loss of benefit to the economy is put at USD 129.2 billion (2005-2009) or 1.8% GDP per annum.On the question of access gap, Telmex’s dominance has led to the various difficulties faced by government authorities in enforcing the social coverage commitments agreed to by the company, firstly as a condition for the exclusive rights granted to it, and subsequently as operator of the government-funded Social Coverage Fund, resulting in a lack of process transparency in the use of resources and little improvement to service accessibility. In short, the two types of gap - market efficiency and access - have different underlying causes and distinct policy implications. However, in the case of Mexico, there is a common factor in both cases: the power exercised by the dominant operators over regulatory authorities. As a result, it is in Mexico’s poorest states, home to 33.3% of the country’s population and 37.8% of the rural population, that low penetration rates are most evident.The aim of the present research is to examine the implications of such market power for achieving socially equitable and affordable access to high-quality telecommunications services (1990-2011). The study examines the coverage of telecommunications services in various regions of the country, ranked according to their respective level of development, analyses the scope of public policies on universal service provision and presents the main research results regarding these policies (1990-2011). The sources underlying this research are the recently published Household Survey of Access to and Use of Information Technologies and Household Survey of Income and Expenditure, recent information on regional economic development based on Poverty Indexes and growth and employment figures from Mexico’s Census Bureau (2010), and statistics published by the Ministry of Communications and Federal Telecommunications Commission (2011).In the light of available evidence, the paper discusses possible explanations for the apparent failure of previously-implemented policies to bring telecommunications services to those regions of Mexico lacking coverage (access gap). It also examines the difficulties faced by the regulatory bodies behind the design and implementation of pro-competition policies that could help to improve service density through increased affordability (market efficiency gap).

Microstructured fiber source of photon pairs at widely separated wavelengths

We demonstrate a source of photon pairs with widely separated wavelengths, 810 and 1548 nm, generated through spontaneous four-wave mixing in a microstructured fiber. The second-order autocorrelation function g((2))(0) was measured to confirm the nonclassical nature of a heralded single-photon source constructed from the fiber. The microstructured fiber presented herein has the interesting property of generating photon pairs with wavelengths suitable for a quantum repeater able to link free-space channels with fiber channels, as well as for a high-quality telecommunication wavelength heralded single photon source. It also has the advantage of potentially low-loss coupling into standard optical fiber. These reasons make this photon pair source particularly interesting for long-distance quantum communication.

International telecommunications service management

This paper discusses the importance of high-quality telecommunication service management and discusses the standards used in international telecommunications service management. Telecommunication service management and standards are tightly coupled with each other as better standards result in better service management. The major standardisation bodies that are responsible for creating the technical specifications of major telecommunication service management standards are ITU-T, TeleManagement Forum (TM Forum) and International Organization for Standardization (ISO). A state-of-the-art survey of the telecommunications service management arena and forecast of the future direction and applications of international telecommunications service management standardisation are described.

Telecommunications markets, industry, and infrastructure in Korea

Following the successful deployment of basic telecommunications networks and services in the 1970s and 1980s, Korea's telecommunications sector has undergone significant environmental and technical changes. Among these are the introduction of competition in the telecommunications market, the allowance of foreign ownership of telecommunication services, and the deployment of new networks and services, all within a new legal framework. As demands for more diversified and high-quality telecommunications increase, Korea is now preparing for a major communication infrastructure that can serve as a common network foundation. Named the Korea Information Infrastructure, it is planned to provide a new network foundation that will serve as the core of the information society in the 21st century. This article describes the current status of and future perspectives on the Korean telecommunications markets, industry, and infrastructure.

German infobahn trials for the residential customer: Technological and conceptual analysis

No other area of the upcoming Information Superhighway promises providers of technology and content as many business opportunities as Interactive Television (ITV). In Germany, one of the technologically most advanced countries in Europe with a high quality telecommunication network, six pilot projects are underway. Each has a different approach and varying participants, although all pilots are dominated by the Deutsche Telekom as network monopolist. These technology-driven trials lack an application-oriented point of view which is necessary to explore the consumers' acceptance under real everyday conditions. In addition, the political funding based on the “multimedia” hype adds to the current uncertain situation.

Electronic Databases: A Brief Survey

As the bank slogan goes, electronic deposit, you could be somewhere else today (and not standing here in line), so too, with electronic data sources, we can spend our time much more efficiently reading, analyzing or, better yet, writing up the results of our research instead of wading through page after page of citations, juggling several tomes at one time as we try to cross reference our data and write the results out on notecards or pieces of paper. Electronic information sources can produce in seconds results that take hours by hand. Because they require less effort and save so much time, they invite us to look for data in ways that before we would have discarded as being too time-consuming. What follows is a survey of some of the traditional and non-traditional electronic sources of information that can be of use to us in research and teaching. Dialog Information Services of Palo Alto, California provides access to three hundred databases containing over 152 million units of information. Several of these are of traditional interest to the hispanist, though we are probably more accustomed to thumbing through their pages than viewing their contents electronically: the MLA International Bibliography, ERIC (Educational Resources Information Center), Dissertation Abstracts, and Linguistics and Language Behavior Abstracts. The MLA International Bibliography contains citations to over 850,000 documents in literature, language, linguistics, and folklore from 1964 to 1987. It is updated monthly from December through May and again in September. These updates will continue until everything from 1921 to the present is available. The cost of searching this database is $66.00 per hour, plus the cost of connecting to it, and 15 cents for each citation printed off line and mailed to you, typed, or displayed on your screen. Special rates of $15.00 per hour are available to academic institutions and there are discount contracts for high usage accounts. There is an annual contract fee of $25.00 for your password and there are no minimum use charges. You connect to the MLA International Bibliography or other database with your modem through a local telelcommunications network such as Telenet or Tymnet. There is a $10.00 per hour charge for using these networks in addition to the cost of connecting to Dialog. In a limited number of cities Dialog provides its own communications service, Dialnet. Connections are made at 300, 1200, and in most cases, 2400 baud. Dialog is available twenty-four hours a day everyday except Sunday from 3:00 a.m. to 3:00 p.m. Dialog will provide communications software for the IBM family of microcomputers specially developed for use on their network should you wish to purchase it. However, any high quality telecommunications program can be used and most of these will allow you to save to disk whatever appears on your screen. Dialog Information Services provides a wealth of information on all of its databases from the moment you subscribe, and you are kept up to date through periodic supplements to the original materials that you receive.' The chapter dealing with searching the MLA International Bibliography is forty-two pages in length and contains detailed instructions for searching, along with samples of searches based on different key words (author, title, special descriptor) that you might use. It also deals with the organizational changes that the MLA made in the International Bibliography in 1981 and their consequent implications for data searches. With practice you can design very sophisticated strategies; however, the details of searching can at first seem quite complicated, if not intimidating. Because of the costs involved, it is imperative that you work out as much of your strategy as possible, well in advance of dialing into Dialog. ERIC contains data from 1966 to the present and costs $30.00 per hour of connect time, plus 14 cents for each citation printed off line or 10 cents for each typed, or displayed on line. Dissertation Abstracts spans from 1961 to the present and costs $72.00 for each

The role of standards in network evolution

As the network evolves in the post divestiture environment, a smoothly functioning standards process will be essential to providing end users with high quality telecommunications services. The major factors supporting the need for standards in today's telecommunications industry structure are examined. Emphasis is placed on interface and performance standards as the key elements needed to provide a framework which assure compatibility and foster innovation. The challenge of the standardization process is that standards need to be implemented to meet today's demands yet be flexible enough to allow for tomorrow's advanced technology and services. The evolution of today's network to Integrated Services Digital Networks (ISDN) with intelligent network capabilities, is supported by the work of a number of national and international standards forums.

Artificial Intelligence For Secure NetworkCommunications

The national telecommunications infrastructure is increasing rapidly in complexity and the numbers of interconnected networks. To ensure high quality telecommunications service, Dr. Johnson and her students are developing an expert system that monitors evolution of the network and rejects proposals for evolution that violate rules that are built into the system. They are using an object-oriented graphical language for the rules and for constructing the user interface. Initially, they are concerned with changing network topologies and the software developed is called an expert system for network configuration. This is one part of their research goal of providing a network planning system that plans network topologies based on demands for service. Their focus is on interconnected voice networks as opposed to the rapidly emerging data services (e.g., email). The methods are expected to apply also to data networks. Three students are involved all of whom are now employed full time at telecommunications companies in Canada and continue their work on the project by providing consultation and writing scholarly papers coauthored by Dr. Johnson. We report investigative and preliminary work undertaken by Johnson and her students at the University of Regina in the area of network communications security, modelling and management.
