RAN Control Mapping for Enrichment Provider Identification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In Open-RAN architectures, the temporary and dynamically updated RAN UE ID poses a challenge for external enrichment information providers to directly identify user equipment, hindering the adjustment of user equipment behavior within the radio access network.
Innovation Solution
An apparatus with a processor, communication interfaces, and a storage device that establishes a mapping table between RAN user equipment identifiers and enrichment information provider identifiers, allowing for the correct association and control of user equipment resources.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a temporary identifier (RAN UE ID) is used for user equipment identification in the radio access network, then security is improved, but the ability of enrichment information providers to directly identify user equipment deteriorates
Solution Approach 1:
The patent introduces an enrichment information provider as an intermediary component that receives temporary RAN UE IDs from the radio access network and maintains a mapping relationship with permanent identifiers. This mediator enables the enrichment information provider to bridge the gap between the temporary security identifiers used in the network and the permanent identifiers needed for user equipment identification, thus resolving the contradiction between security and identifier association capability.
2Adaptability or versatility
If the RAN UE ID is dynamically updated with connection changes, then network flexibility is improved, but the ability to track and control specific user equipment deteriorates
Solution Approach 1:
The patent implements preliminary action by establishing a mapping relationship between temporary RAN UE IDs and permanent identifiers before the dynamic updates occur. The enrichment information provider proactively maintains this mapping table, allowing it to track user equipment through connection changes without being affected by the dynamic nature of RAN UE IDs. This preliminary preparation enables continuous tracking while preserving network flexibility.
3Productivity
If external enrichment information services are integrated into the RAN, then network optimization is improved, but the complexity of identifier management deteriorates
Solution Approach 1:
The patent applies the copying principle by creating a simplified mapping table structure that stores only the essential relationship between temporary and permanent identifiers. Rather than managing complex identifier transformations in real-time, the system copies and stores the mapping relationships in advance, reducing the complexity of identifier management while preserving the network optimization capabilities provided by external enrichment information services.
Data Source
AI summary
An apparatus and a method for radio access network control are provided. A registration state is switched to a closed state and connection information is provided in reply to a base station in response to receiving first identification information of user equipment registered by the base station. In the closed state, in response to receiving second identification information registered by an enrichment information provider, a correspondence between the first and second identification information is established and stored in a mapping table, and the registration state is switched to an open state. In response to receiving enrichment information and the corresponding second identification information provided by the enrichment information provider, the first identification information corresponding to the second identification information is queried from the mapping table, and a control request for the user equipment corresponding to the first identification information is transmitted to the base station according to the enrichment information.
