E2 Node UE ID Signaling for RIC Service Differentiation

The patent introduces the E2 interface as an intermediary communication channel between the RIC and E2 nodes, enabling efficient UE identifier management and service differentiation. The E2 message format serves as a standardized mediator that facilitates information exchange and control signaling, resolving the limitation of traditional 5G systems by providing a dedicated control plane for virtualized network management.

The patent segments the 5G network into virtualized functions by introducing the RIC as a separate intelligent controller that manages UE identifiers and service differentiation. This segmentation allows the RIC to handle complex identification and service management tasks independently from the core network, improving overall system efficiency and adaptability.

The E2 interface and message format serve as universal components that enable the RIC to perform multiple functions including UE identifier management, service differentiation, and resource optimization. This multi-functionality reduces network complexity by consolidating diverse management tasks into a single standardized control mechanism rather than requiring separate specialized systems.

The patent enables self-service capabilities where the RIC autonomously manages UE identifiers and service configurations through the E2 interface. The system performs self-configuration and self-optimization without requiring extensive manual intervention or complex centralized control, thereby reducing operational complexity while maintaining service optimization capabilities.
