User-centric Service System for Network beyond IMT-2020 (5G)

With the extensive deployment of IMT-2020 (5G) network and the emergence of new Internet applications, it also brings some problems and challenges, such as how to manage massive terminal devices conveniently, how to create personalized networks and services flexibly and freely, and how to manage users' private data authority independently. This paper designs a user-centric service system which introduces the Network Functions Depository (NFD) and the Integrated User-centric Service Unit (IUSU). The NFDs provide basic network and service functions. The IUSU deployed in certain application scenario downloads the required network and service functions through NFD to realize the management of massive terminal devices and provide personalized networks and services. Introducing this system in network beyond IMT -2020 (5G) can help users solve the above problems.
