Service-based RAN for 6G Network

This research report analyzes the motivations and requirements for Service-based RAN, which include the customized needs of industry users, capacity exposure, the introduction of new capabilities (AI, sensing) for 6G, service-oriented network management/orchestration and business innovation. For the basic considerations of Service-based RAN, this report analyzes the principles to be followed, including modular service definition, service reusability, self-contained functional structuring, etc., and analyzes the different directions of service implementation from different architectural perspectives such as control plane, user plane, and service access interfaces. Finally, the challenges faced by Service-based RAN are analyzed, including the rationality of service definition, performance impact, UE impact, and interoperability.
