OpenRAN MEC Information Exchange via RM API Aggregation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for exchanging information between Radio Access Networks (RAN) and Multi-Access Edge Computing (MEC) are proprietary and inefficient, leading to interoperability issues and increased complexity, with RAN components not having all necessary information for MEC solutions, such as UE location and performance data.
Innovation Solution
The Enhanced OpenRAN-MEC information exchange solution introduces xApps and rApps for RAN-MEC info exchange, utilizing standard ORAN interfaces and RM API services as an aggregation point, leveraging information shared by RAN functions over O1 and E2 interfaces, and providing a centralized view of UE data.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If proprietary information exchange methods are used between RAN and MEC, then information exchange can be achieved, but interoperability issues arise and complexity increases
Solution Approach 1:
The patent applies universality by implementing a standardized information exchange mechanism that works across multiple vendors and network types. The unified interface and data model allow different RAN and MEC systems to communicate using common protocols, eliminating proprietary dependencies while maintaining reliable information exchange.
Solution Approach 2:
The patent changes the parameters of information exchange by defining standardized data formats, message structures, and communication protocols. This standardization transforms proprietary, complex exchanges into parameterized, predictable interactions that reduce system complexity while maintaining reliability.
2Device complexity
If RAN components have limited information about UE location and performance, then system complexity is reduced, but MEC solution effectiveness deteriorates
Solution Approach 1:
The patent introduces an intermediary information exchange mechanism that collects, standardizes, and transmits UE location and performance data from RAN to MEC. This intermediary layer allows RAN components to maintain simplicity while ensuring MEC receives comprehensive information needed for effective solutions.
Solution Approach 2:
The patent segments the information exchange function into distinct modules: data collection at RAN, standardization processing, and delivery to MEC. This segmentation allows each component to focus on specific tasks, maintaining RAN simplicity while enabling comprehensive information availability for MEC effectiveness.
3Adaptability or versatility
If centralized view of UE data is implemented, then MEC application capability is improved, but information exchange complexity increases
Solution Approach 1:
The patent creates a universal data aggregation mechanism that provides a centralized view of UE data to MEC applications. This universal interface allows diverse MEC applications to access standardized UE information without dealing with underlying complexity, enhancing adaptability while managing complexity through standardization.
