Technical Challenges and Categorization of 5G Mobile Services

With the explosive increase in mobile and Internet of Things (IoT) networks, 5G mobile networks is being deployed to improve the user experiences with new types of services, like Augmented Reality (AR), Virtual Reality (VR), Ultra-High-Definition (UHD) videos, smart offices, and seamless interactive user experiences. Based on the performance attributes of such services, the International Telecommunication Union - Radiocommunication Sector (ITU-R) recommended three main categories of usage scenarios for 5G networks: enhanced Mobile Broadband (eMBB), massive Machine-Type Communications (mMTC), as well as Ultra-Reliable and Low-Latency Communications (URLLC). Based on the Key Performance Indicators (KPIs) of such scenarios, we propose to divide the services offered into 3 families: broadband multimedia services, Machine-Type Communications (MTC) services, and mission critical services. For each service family, we identify and characterize the most significant categories of use cases, in terms of their main requirements. The proposed service categorization may serve as a guide for operators, and may help them to be efficient in future deployment of 5G mobile services in the world.
