5G Network Slicing is one of the central features of 5G. Network Slicing essence is in sharing network resources (PNFs, VNFs, CNFs) while satisfying multiple, sometimes contradictory requirements. Same network is expected to provide different Quality of Experience to different consumers. An End-to-End Network Slice consists of RAN, Transport and Core network slice sub-nets. This Use Case intends to demonstrate the modeling, orchestration and assurance of a simple network slice (e.g. eMBB). While 3GPP standards are evolving and 5G Core is emerging, the Use Case will start with simple example of a 5G RAN Network Slice sub-net.
Business Impact - x.Business Markets - xA feature that almost every service provider will leverage. Therefore, developing it once improves efficiency. It allows a service provider to improve their network efficiency by maximizing the network throughput more tailored to each user's use of the network. It is seen as an imperative for efficient and optimal use of their network. This will be particularly relevant as 5G is expected to have upwards of 10,000x the traffic load over 4G and 20GB peak data rates.
Business Markets - Network is a 5G specific function evolved from 4G. This is the functionality that almost every wireless service provider will find valuable. The concepts and modeling work being done for Network slicing will find applications in other areas as well. (Sector/Domains) Transport and core aspects of network slicing will eventually be incorporated into this use case. These domains also play a part in defining and managing a network slice as well. (Industries) Some applications and industries such as remote maintenance, video streaming vs life-saving first-responder type applications will demand different requirements from Network slicing. (Markets Regions) There are no regional specific aspects to Network Slicing.
Funding/Financial Impacts - x Network slicing engenders the optimal use of resources for a Network. Thus, this represents OPEX savings for a service provider.
Organization Mgmt, Sales Strategies - There is no additional organizational management or sales strategies for this use case outside of a service providers "normal" ONAP deployment and its attendant organizational resources from a service provider.
R4 DEVELOPMENT SCOPE
In R4 (Dublin) release only modeling of 5G Network Slicing will be provided.
