Network slicing creates specialized, dedicated logical networks as a service (NaaS) in support of network service differentiation and meeting the diversified requirements from vertical industries. Through flexible and customized design of functions, isolation mechanisms, and O&M tools, network slicing is capable to provide logical dedicated networks upon a common infrastructure.
The 5G core network provides customized network slicing services for specific business and network scenarios.
In order to achieve this "network slice as a service", according to different business needs,
Based on unified physical facilities, generate the appropriate network topology and network functions based on virtualization. for each specific business type generated a series of network functions construct a network slice.
Physically, each network slice runs on a unified network infrastructure that can greatly reduce the cost of network construction for multiple different business types;
Logically, each network slice is separated to meet every type of business function Custom, independent operation and maintenance needs.
