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.
