Unified UE Identifier Allocation for 5G Security and Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In 5G systems, the allocation of User Equipment (UE) identifiers is complex, leading to security issues and frequent handovers due to the locality of these identifiers, which are not effectively managed across multiple base stations.
Innovation Solution
A method and apparatus for allocating a UE identifier, where a preset function entity or module, such as a near Real Time Radio Intelligent Controller (nRT RIC) or a non Real Time Radio Intelligent Controller (NRT RIC), allocates a unified UE ID that is decoupled from specific network systems, ensuring security and stability across multiple base stations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If local UE identifiers are used in each base station, then the identifiers are simple to allocate and manage locally, but security issues arise and frequent handovers occur when UEs move between base stations
Solution Approach 1:
The patent segments the UE identifier into two parts: a global part (G-PART) that remains constant across the network and a local part (L-PART) that is specific to each base station. This segmentation allows the global part to provide security and stability while the local part enables simple local allocation and management.
Solution Approach 2:
The patent introduces a mapping relationship between the global UE identifier and local identifiers as an intermediary mechanism. This mapping allows different base stations to use their own local identifiers while maintaining security through the global identifier, resolving the contradiction between local ease of allocation and global security stability.
2Reliability
If UE identifiers are tightly coupled with specific network systems, then the identifiers provide strong security protection, but adaptability decreases when UEs need to be recognized across multiple base stations
Solution Approach 1:
The patent segments the UE identifier into a global part for security and a local part for base station-specific recognition. This allows the global part to maintain security coupling with the network system while the local part provides adaptability for cross-base station recognition.
Solution Approach 2:
The patent makes the global UE identifier universal by establishing a mapping relationship that works across multiple base stations. The global identifier can be used for security purposes while the local identifier provides base station-specific recognition, achieving multi-functionality that resolves the contradiction between security coupling and cross-base station adaptability.
3Adaptability or versatility
If multiple different UE identifiers are used across different network elements, then each identifier can be optimized for its specific usage scenario, but the system complexity increases significantly
Solution Approach 1:
The patent segments the UE identifier structure into consistent global and local parts, providing a unified framework that simplifies management. This segmentation allows each part to be optimized for its specific scenario while maintaining overall system simplicity through a consistent structure.
Solution Approach 2:
The patent changes the parameter structure of UE identifiers from multiple different formats to a unified format with consistent global and local parts. This parameter standardization maintains the adaptability needed for different scenarios while significantly reducing system complexity through uniformity.
