A Review of Network Slicing in 5G and Beyond: Intelligent Approaches and Challenges

Artificial intelligence has the ability to provide simple solutions to complex problems by analyzing huge volumes of data in a short amount of time with appropriate accuracy. With the emergence of slicing technology, Fifth Generation communication networks(5G) are becoming more complex due to supporting a large number of new connected devices and new types of services. Concerning this complexity, intelligent techniques can become beneficial in these networks. In this paper after a brief review of network slicing through a new functionality model including design, deployment, monitoring and management of slices, the need for automation of network operations in network slices is discussed. Our investigation of recent research has shown that artificial intelligence and machine learning have a clear potential to become one of the most important enablers in the 5Gnetwork and beyond.
