Solution Overview
Problem
Existing systems lack effective methods for an RAN intelligent controller (RIC) to generate and transfer messages with error details when controlling E2 nodes in a wireless communication system, leading to unclear failure reasons and suboptimal control outcomes.
Innovation Solution
The implementation of a method and apparatus that enable the RIC to transmit and receive RIC control request and acknowledge/failure messages, including RAN parameter IDs and values, allowing the E2 node to notify the RIC of control outcomes and failure reasons.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If e2 node performs both relay and local breakout functions, then service continuity is improved, but resource consumption increases
Solution Approach 1:
The e2 node dynamically adjusts its operational mode by determining whether to perform relay function, local breakout function, or both, based on real-time network conditions and service requirements. This dynamic adaptation allows the system to optimize resource consumption while maintaining service continuity only when necessary.
Solution Approach 2:
The system changes operational parameters of the e2 node based on determined functions. When relay function is selected, parameters are configured for forwarding traffic through the network. When local breakout is selected, parameters are adjusted to enable local traffic termination. This parameter adaptation resolves the contradiction by optimizing resource usage according to actual service needs.
2Reliability
If e2 node determines function based on multiple factors, then service quality is improved, but determination complexity increases
Solution Approach 1:
The determination process is segmented into distinct steps: first determining relay function based on traffic type and network conditions, then independently determining local breakout function based on service requirements and available resources. This segmentation reduces overall complexity by breaking down the multi-factor decision into manageable sub-decisions.
Solution Approach 2:
The system performs preliminary determination of relay function before local breakout function. By first establishing whether relay function is needed based on traffic characteristics and network state, the system prepares the foundation for subsequent local breakout determination, simplifying the overall decision process while maintaining service quality.
3Adaptability or versatility
If e2 node configures multiple functions, then network flexibility is improved, but configuration time increases
Solution Approach 1:
The system performs preliminary determination of functions before actual configuration execution. By pre-determining which functions (relay, local breakout, or both) should be configured based on network conditions and service requirements, the system avoids unnecessary configuration attempts and reduces overall configuration time while maintaining network flexibility.
Solution Approach 2:
The configuration process is made dynamic by adjusting the configured functions based on real-time network conditions. The system dynamically selects between relay function, local breakout function, or both, and updates configurations accordingly. This dynamic approach maintains network flexibility while reducing configuration time by avoiding static, time-consuming multi-function configurations when single functions suffice.
