Abstract
5G technology is the future of mobile networks, and in different countries, 5G mobile networks are launched. Different use cases have different requirements for the function and the performance of 5G network. They would require different types of factors and networks which include data rate, delay and scalability. Those requirements will be met in 5G by using network slice architecture, which uses network virtualization technology The paper will analyze the state-of-the-art 5G network slice, address a number of network slicing architecture issues, and highlight some open research questions.
I. Introduction
The 5G technology is providing high-speed communication services because it is using millimeter waves to transfer data from one location to another location. 5G is also supporting many devices because the network speed is very high. It can be improved by introducing a new architecture, and this architecture is known as network slicing. Network slicing is an important architectural technology for 5G [1], [2].
Network slicing is the most important concept to realize personalization of mobile networks for users [3]. Basically, logical networks will be virtually representing the 5G single physical network, and each one called network slice. Every network slice will have specific network functions to provide different services for different requirements. Network slicing offers better business agility, flexibility, and cost-efficiency.
