Abstract
In this paper, emerging 5G mobile services are investigated and categorized from the perspective of not service providers, but end-users. The development of 5G mobile services is based on an intensive analysis of the global trends in mobile services. Additionally, several indispensable service requirements, essential for realizing service scenarios presented, are described. To illustrate the changes in societies and in daily life in the 5G era, five megatrends, including the explosion of mobile data traffic, the rapid increase in connected devices, everything on the cloud, hyper-realistic media for convergence services and knowledge as a service enabled by big-data analysis, are examined. Based on such trends, we classify the new 5G services into five categories in terms of the end-users’ experience as follows: immersive 5G services, intelligent 5G services, omnipresent 5G services, autonomous 5G services and public 5G services. Moreover, several 5G service scenarios in each service category are presented, and essential technical requirements for realizing the aforementioned 5G services are suggested, along with a competitiveness analysis on 5G services/devices/network industries and the current condition of 5G technologies.
Highlights
Information and communication technologies (ICT) have been regarded as key ingredients for social and economic development because they have created new benefits and conveniences that were not experienced before
We examine the diverse 5G services, categorization of services and their technical requirements defined by other groups, such as International Telecommunication Union-Radiocommunication Sector (ITU-R), 3rd Generation Partnership Project (3GPP) services and markets technology enablers (SMARTER) and Next Generation Mobile Networks (NGMN)
The concept of smart transportation refers to a transportation system that enables improved safety, higher productivity and efficiency with the help of a network infrastructure. 5G combined with artificial intelligence (AI) algorithms is one of the main enabling technologies for such smart transportation systems
Summary
Information and communication technologies (ICT) have been regarded as key ingredients for social and economic development because they have created new benefits and conveniences that were not experienced before. Since 4G wireless network services were introduced, people have been able to experience broadband services with their mobile devices (e.g., smart phones and tablet PCs), and the end-user experience has become nearly equivalent to that of wired connections. In spite of such advanced 4G wireless network technologies, it is hard to provide mobile services that require high speed, rapid response, high reliability and energy efficiency. For the preparation of the 5G network infrastructure, we first analyze the megatrend of mobile services Based on this analysis, detailed service scenarios are defined and categorized depending on the characteristics of such services. The technical requirements for both the wireless communication and the core network sides are examined and proposed in this paper
