Implementation of 5G Telecommunication Network Services in Indonesia based on Techno-economic Analysis

The 2300 MHz spectrum is a medium band that telco operators will not pay much attention to when they deploy 5G. They are more comfortable at 2.6 GHz, 3.5 GHz, 26 GHz, and 28 GHz, in addition to 700 MHz for the breadth of coverage. The performance of cellular telecommunications services based on 5G technology is possible for new operators, although it will be carried out as stand-alone services. This opportunity will be taken by looking at internet subscriber data/data communication from existing operators as active internet users, which is quite large and has a potential of over 250 million users. There has been no previous study regarding the feasibility of deploying this 5G technology-based Broadband Wireless Access (BWA) Network. Based on the experience of implementing previous generations of telecommunication service technology, the government and operators need to be careful in determining the right moment to deploy this 5G technology service, which is predicted to be able to provide broadband services with streaming capabilities of 10 to 100 times the streaming speed of 4G technology. It should be noted that the lack of success of 3G performances in 2006 from 2G, 2.5G, and 2.75 G. Almost all operators who were expected to be very lucky turned out to be not optimal; even now, only 4 operators are playing on 3G. where they have not been able to force users of the 2G generation to switch to 3G, including in big cities where the performance of the 3G network is not yet optimal and evenly distributed. Still, many areas are blank spots from 3G networks and services. From this experience, scientific studies are needed to ensure the feasibility of the upcoming 5G BWA business and identify business opportunities that can be implemented. The feasibility analysis must be viewed from various aspects, namely aspects of technical readiness, market aspects, and financial aspects in terms of the techno-economics of the operators who will provide 5G telecommunications services by calculating several essential parameters as a measure of business feasibility, namely Net Present Value (NPV), Internal Rate of Return (IRR), and Payback Period (PBP).

The integrated sphere of coopetition of digital services and the regulatory approach of diagonal equity

Telecommunications Service providers (TSPs) and Content and Application Providers (CAPs) that operate over the Internet are traditionally regarded as complementary. However, the growth of 5G technologies has led to the emergence of an integrated sphere of competition and cooperation between TSPs and CAPs.The new elements of this competitive landscape stem from the hybridization of network provisioning, the growth of substitute services, and the emergence of end to end value networks comprising of devices, connectivity solutions, and a variety of content and application services. Simultaneously, the regulatory drivers that occasioned a differential treatment of TSP in their role as providers of essential utility communication services are converging with the features observed with respect to certain CAPs. These dynamics warrant the application of a new regulatory framework in the form of Diagonal Equity, that recognizes the need for similar regulatory principles to be applied to TSPs and CAPs, while acknowledging that with respect to certain issues a differential treatment will continue to be required.

Editorial

This editorial argues from content in this issue that telecommunications regulation has not kept pace with convergence of telecommunications and content providers. It suggests that the loose co-ordination between regulations and regulators for telecommunications services and digital platforms no longer makes technological sense within the converged architectures of 5G and 6G.
 In addition, all the published papers, not just those relating to regulation, are briefly described. This issue also includes an obituary for John Burke, an influential member of this Journal’s Editorial Advisory Board.

Extreme risk measurement for the oil and China’s sectors system—network-based approach and machine learning methods

China is a large oil-consuming country, and sharp fluctuations in oil prices are bound to be detrimental to the stable growth of its economy. Therefore, accurately grasping the impact of the oil market on China’s sectors is the key to ensuring its healthy economic development. The article aims to explore the extreme risk transfer link of the oil and China’s sectors system, focusing on uncovering the risk spillover mechanism of the oil and providing early warning on it. We apply the TENET method to discuss risk propagation relationships within the oil and sectors system at three levels. The TVP-VAR model is brought in to recognize the factors affecting risk spillover in the oil market from the network correlation perspective. Finally, early warning of oil risk spillover is provided by incorporating the influencing factors into a machine learning model. The outcomes indicate that the risk connectivity of the oil and China’s sectors system is highly correlated with extreme events. There are variations in the spillover effects of oil market risk on different sectors, with Telecommunication Services, Utilities, Financials and Major Consumer sectors being the main bearers of the oil risk shocks. Overall, oil risk spillovers are mainly driven by economic policy and geopolitics, but oil price uncertainty is found to have a persistent impact on oil market risk spillovers in the dynamic analysis. Random forest model can provide effective early warning of oil risk spillovers. In addition, the significance analysis shows that oil price uncertainty and inflation are important factors affecting oil risk spillovers and are nonlinearly correlated with them.

Hedera: A Permissionless and Scalable Hybrid Blockchain Consensus Algorithm in Multiaccess Edge Computing for IoT

Abstract-Multi-access edge computing network (MEC), as one of the key infrastructures of IoT, provides cloud computing capabilities at the edge of radio access network (RAN) by integrating telecommunication and IT services. Integrating blockchain into the MEC network can provide users with secure, private, and traceable edge computing services at the near end, thereby improving IoT security, privacy, and automated use of resources. Due to some characteristics of the MEC network, there are still some challenges to integrate blockchain and edge computing into one system, especially the consensus algorithm of blockchain. The resources of edge computing nodes are limited, and the scale of the network is constantly expanding. Therefore, the blockchain consensus algorithm for the MEC network should occupy as little computing resources as possible, be green, and be permissionless. This paper proposes a permissionless and scalable consensus algorithm "Hedera" for multi-access edge computing network, which has the advantages of permissionless, security, decentralization, scalability, and greenness. The Hedera consensus algorithm is a hybrid blockchain consensus algorithm that combines the permissionless proof-of-capacity algorithm and the permissioned asynchronous Byzantine algorithm. This paper tests the fairness, throughput, scalability, latency, and resource consumption of the algorithm by developing and deploying a prototype system. The experimental results show that the Hedera algorithm proposed in this paper is fair, the throughput reaches 13986.3TPS, and the resource consumption is much lower than the PoW consensus. By analyzing its security and liveness, it can resist Sybil attack, Nothing-at-stake attack, selfish mining attack, message hijacking attack, and has good liveness.

ANALYSIS OF METHODS FOR DETERMINING THE QUALITY OF FUNCTIONING OF TELECOMMUNICATION SYSTEMS

The rapid development and spread of information and communication technologies is taking on the character of a global information revolution today. Users have a need for communication services that can be flexibly configured. Next Generation Networks (NGN) - the modern stage of development of telecommunication networks (TCN) - represent a single transport platform on the basis of which various types of services are combined. One of the main aspects that should be taken into account when designing NGN is the provision of appropriate quality of service. With the introduction of multi-service networks, the approach to the task of service level based on the requirements of the users themselves for the quality of services becomes predominant, which requires the improvement of methods of managing the quality of services in TCN. The analysis of the works of domestic and foreign scientists regarding service quality management in TCN indicates the need to improve service quality management methods. It should be noted that in the works on the quality management of telecommunication services (TCS), attention is mainly paid to the technical indicators of the quality of services, while the development of effective methods of taking into account the user's opinion in managing the quality of services is currently relevant. The existing subjective methods of assessing the quality of TCS take into account the quality of the transmitted media information based on expert assessments, but do not provide a full assessment of the quality of the service by the user. The ITU-T recommendations describe different points of view on the quality of service, but do not provide specific methods for evaluating and managing the quality of TCS taking into account the opinion of the user. It is the unsolved task of comprehensive assessment of the quality of services in next-generation TCN that determined the purpose of this work.
