- Abstract
- Initially, the 5G system architecture is required with very diverse and extreme requirements. These requirements related with four main mega trends. Those are the explosion of date traffic, the rapid increase of number of devices, the increase of cloud's dependency, and the advent of new various mobile converged services. Mobile business stake holders define three categories of services and their characteristics such as eMBB (enhanced Mobile Broadband), mMTC (massive Machine Type Communications) and URLLC (Ultra-Reliable and Low Latency Communications). To support these services, KPIs (Key Performance Index) such as user experience data rate, peak data rate, mobility, latency, connection density, energy efficiency, spectrum efficiency, and traffic volume density are elicited. With these KPIs and service scenarios, 3gpp working groups has been studied requirements, standards, and use cases for the 5G system. To support these 5G's requirements, a network slicing technology is required. Network Slicing provides multiple logical networks on top of a partially shared network infrastructure. Each instance of a network slice represents an independent end-to-end network that allows deployment of different architectural flavours in parallel slices. This paper proposes an architecture for the network slicing in 5G communication system.
