RAN User Identification Mapping for Differentiated Services
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current 4G/5G communication systems lack the ability to specify a user in cell-related information collected by the radio access network (RAN) or open radio access network (O-RAN), making it impossible to provide differentiated services to users.
Innovation Solution
A method and apparatus for identifying a user equipment (UE) and generating a unique identifier, such as a 5G-globally unique temporary identifier (5G-GUTI) or globally unique temporary identifier (GUTI), based on information transmitted from the UE and network entities like AMF or MME, and transmitting this information to other nodes for mapping and processing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If user identification is implemented in RAN/O-RAN, then differentiated service capability is improved, but system complexity increases
Solution Approach 1:
The patent introduces a mapping relation mechanism as an intermediary between the RAN UE identifier (used in RAN) and the unique identifier (used in core network). This mapping table acts as a mediator that enables user identification in RAN without requiring direct integration between RAN and core network user identification systems, thus adding differentiated service capability while limiting complexity growth to a manageable mapping component.
2Measurement precision
If mapping relation information is transmitted between nodes, then user identification accuracy is improved, but information transmission overhead increases
Solution Approach 1:
The patent extracts only the essential mapping relation information (RAN UE identifier and corresponding unique identifier pairs) needed for user identification and transmits this extracted subset between nodes. Rather than transmitting all user data or complete identification systems, only the necessary mapping entries are exchanged, achieving accurate user identification while minimizing information overhead.
3Reliability
If user-specific monitoring is implemented, then service quality is improved, but network resource consumption increases
Solution Approach 1:
The patent enables user-specific monitoring and differentiated services to be applied locally to specific users who require enhanced service quality, rather than implementing universal monitoring for all users. The mapping relation mechanism allows the network to selectively apply monitoring resources to users with specific service requirements, improving service quality for targeted users while avoiding unnecessary resource consumption for users with standard service needs.

AI summary
A method and an apparatus for identifying a user in a radio access network (RAN), and a first node in the wireless communication system are provided. The method includes identifying a unique identifier of a UE, identifying a radio access network (RAN) UE identifier of the UE, and transmitting information related to a mapping relation between the RAN UE identifier and the unique identifier of the UE to a second node, based on the unique identifier of the UE.
