AI Technical Summary
Current 4G/5G communication systems face challenges in providing differentiated service support for users in virtualized networks, particularly in efficiently managing and optimizing radio resources across a wide range of cells and network slices.
The method involves using E2 Subscription messages to request services from O-DU, O-CU-CP, or O-CU-UP nodes in the O-RAN architecture, allowing for the configuration of call processing events and the generation of E2 INDICATION/REPORT messages based on specific conditions, thereby enabling effective resource optimization and user-specific service provision.
This approach facilitates an efficient subscription procedure between the RIC and E2 nodes, allowing for optimized resource management and differentiated service support across multiple cells and network slices, thereby enhancing the overall performance and flexibility of the 4G/5G communication systems.
