Summary:
|
The service-based network (SBN) is a type of network architecture that is based on the concept of service-based architecture (SBA). In an SBN, network resources and services are exposed as standardized, reusable building blocks that can be easily integrated and composed to create new and innovative network services.
In the current ITU-T Y.3012, the similar concepts of service-based network are mentioned like network service framework, network service functions and etc. However, the service-based network lack of systematic sorting, the problem of what capabilities it has, its role in the network, and the benefits it brings haven’t be addressed, etc. Also the service-based of UPF, even for UE and AN are still far from being achieved, and further enhancements for IMT-2020 network are needed based on the these specifications. Therefore, further study is needed on enhancement of service-based network in IMT-2020 networks and beyond.
This Recommendation specifies the general considerations, requirements, framework, network function enhancements, procedures, and security considerations of service-based network in IMT-2020 networks and beyond.
