- ment for logically independent network slicing based on a single network (physical) infrastructure to meet the 5G service requirements; and to provide dual-connectivity- based cloud architecture to support various deployment scenarios. The network design further relies on C-RAN architecture to deploy different radio access technologies in order to provide multi-standard connectivity and to implement on-demand deployment of RAN functions required by 5G services. It simplifies core network architecture to imple- ment on-demand configuration of NFs through control and user-plane separation, component-based functions, and unified database management. It further implements automatic network slicing service generation, maintenance, and termination for various services to reduce operating expenses through agile network operation and management. 3GPP TS 22.261 specification, service requirements for the 5G system, contains perfor- mance targets and basic capabilities prescribed for the 5G networks. Among those require- ments, one can distinguish support for fixed, mobile, wireless, and satellite access technologies; scalable and customizable network that can be tailored to serve multiple ser- vices and vertical markets (e.g., network slicing, NFV); resource efficiency for services ranging from low-rate Internet of things (IoT) services to high-bandwidth multimedia ser- vices; energy efficiency and network power optimization; network capability exposure to allow third party Internet service providers and Internet content providers to manage net- work slices, and deploy applications in the operator's service hosting environment; indirect connectivity from a remote UE via a relay UE to the network; and service continuity between indirect connections and direct connections. 3GPP TS22.261 defines performance targets for different scenarios (e.g., urban macro, rural macro, and indoor hotspot) and appli- cations (e.g., remote control, monitoring, intelligent transport systems, and tactile communications).
