RAN UE Identifier Mapping for Dynamic Individual Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current management systems in RANs lack the capability to dynamically manage individual user equipment (UEs) due to limitations in SPID and QCI configurations, making it impractical to address individual UEs effectively.
Innovation Solution
Implementing a new interface between the RAN and a management system, utilizing Open Network Automation Platform (ONAP) and Open RAN architecture, to facilitate dynamic control of individual UEs through identifiers like RAN Mgmt UE ID, SUPI, and GUTI, enabling per-UE optimization and policy enforcement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If SPID and QCI classification is used for UE management, then network resource configuration is simplified, but individual UE dynamic control capability is lost
Solution Approach 1:
The patent segments UE management into two layers: group-level management using SPID/QCI for general resource allocation, and individual UE management using RAN UE ID for dynamic control. This segmentation allows the system to maintain simple group configuration while enabling flexible individual UE policies through the new RAN UE ID interface.
Solution Approach 2:
The patent introduces RAN UE ID as an intermediary identifier that bridges the gap between group-based SPID/QCI management and individual UE control. The RAN UE ID acts as a mediator that can be mapped to SPID/QCI for resource allocation while enabling individualized policies through the management system interface.
2Stability of the object's composition
If legacy SPID and QCI interfaces are used, then existing network infrastructure is maintained, but per-UE optimization and dynamic control are not enabled
Solution Approach 1:
The patent merges the legacy SPID/QCI interface with the new RAN UE ID interface in a unified management architecture. The RAN UE ID interface is built upon the existing SPID/QCI framework, allowing both group-based and individual UE management to coexist and work together, thus maintaining infrastructure stability while enabling per-UE optimization.
Solution Approach 2:
The patent introduces dynamic capabilities to the static SPID/QCI framework by enabling real-time individual UE policy enforcement through the RAN UE ID interface. This allows the network to dynamically adjust per-UE treatment based on current conditions while maintaining the stable group-based configuration infrastructure.
3Adaptability or versatility
If individual UE identification is implemented, then per-UE policy enforcement is enabled, but management system complexity increases
Solution Approach 1:
The patent designs the RAN UE ID interface to serve multiple functions: individual UE identification, policy enforcement, measurement configuration, and resource allocation. By making the interface universal, the patent avoids creating separate complex subsystems for each function, thus enabling per-UE policy enforcement without proportionally increasing management system complexity.

AI summary
According to some embodiments, a method performed by a network management system for managing one or more radio access networks (RANs) comprises receiving an indication from a RAN that a RAN identifier has been assigned for a wireless device, associating a management system identifier for the wireless device with the RAN identifier for the wireless device; and storing the association in a wireless device registry.
