Near-RT RIC Subscription Auditing for E2 Node Synchronization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In the context of evolving wireless communication systems, particularly in 6G, there is a need for efficient subscription audit mechanisms to manage and synchronize subscription information between E2 nodes and Near-RT RICs, ensuring accurate and consistent service provisioning in service-based networks.
Innovation Solution
A method and electronic device are provided for a subscription audit, involving the transmission and reception of RIC subscription audit request and response messages between a Near-RT RIC and an E2 node, which include subscription information such as RAN function IDs and RIC request IDs, to ensure synchronized and accurate subscription management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If subscription information is manually managed between E2 nodes and Near-RT RICs, then service provisioning can be controlled, but synchronization accuracy and reliability deteriorate due to manual errors and delays
Solution Approach 1:
The E2 node autonomously performs subscription audit by unilaterally sending audit request messages to the Near-RT RIC and processing the responses to identify mismatches. This self-service mechanism eliminates the need for complex manual coordination while improving synchronization reliability through automated detection and correction of subscription inconsistencies.
2Measurement precision
If comprehensive subscription audit is performed to ensure synchronization accuracy, then service provisioning reliability improves, but resource overhead and processing time increase
Solution Approach 1:
The subscription audit mechanism selectively audits only the necessary subscription parameters and uses efficient message-based communication to verify synchronization status. By implementing targeted auditing rather than comprehensive manual verification, the system achieves high accuracy in subscription status detection while minimizing processing time and resource overhead.
3Productivity
If subscription information is not synchronized between E2 nodes and Near-RT RICs, then resource overhead is reduced, but service provisioning consistency deteriorates
Solution Approach 1:
The Near-RT RIC sends feedback responses to E2 node audit requests, providing information about current subscription status. This feedback mechanism enables the E2 node to detect and correct synchronization mismatches automatically, ensuring service provisioning consistency without requiring continuous manual intervention or excessive resource overhead.

AI summary
In accordance with an embodiment of the disclosure, a method performed by a near-real time radio access network intelligence controller (Near-RT RIC) is provided. The Near-RT RIC transmitting, by the Near-RT RIC to a E2 node, a radio access network intelligence controller (RIC) subscription audit request message to audit one or more RIC subscriptions on the E2 node, the RIC subscription audit request message including subscription information of the one or more RIC subscriptions, and receiving, by the Near-RT RIC from the E2 node, a RIC subscription audit response message in response to the RIC subscription audit request message, wherein the RIC subscription audit response message includes subscription information of at least one RIC subscription recognized in the E2 node, among the one or more RIC subscriptions, and wherein, for each of the least one RIC subscription recognized in the E2 node, the subscription information includes a radio access network (RAN) function identifier (ID) and a RIC request ID.
