- Abstract
- The emergence of new service scenarios driven by user needs beyond 2020 generates new mobile network requirements. Current 4G LTE (Long Term Evolution) network is not enough to fulfill arising new requirements because of fundamental problems in Evolved Packet Core (EPC), including centralized routing mechanism. In this regard, 5G mobile network architecture needs to be redesigned for emerging use cases. In this paper, we present network slice architecture for 5G core network and provide working mechanisms for slice selection, NAS routing, and slice reselection to support multiple logical networks over a single physical network.
