Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The static Reliability Group (RG) approach in 3GPP for redundant user plane paths based on multiple terminal devices per terminal device group fails to ensure efficient redundancy and ultra-reliability in certain scenarios, particularly in dynamic environments with varying cell load, terminal device mobility, and changing radio channel conditions.
Innovation Solution
A centralized coordination system utilizing artificial intelligence (AI) and machine learning (ML) capabilities to dynamically manage Reliability Groups (RGs) by leveraging real-time status information from terminal and network devices, optimizing redundancy and diversity through dynamic RG setup, management, and selection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a static Reliability Group (RG) approach is used for redundant user plane paths, then the network configuration is simple and easy to manage, but the redundancy efficiency and ultra-reliability cannot be guaranteed in dynamic network conditions
Solution Approach 1:
The patent applies dynamics by transitioning from a static RG configuration to a dynamic one where RGs are continuously adjusted based on real-time network conditions. The network controller dynamically establishes, modifies, and releases RGs according to changing cell load, terminal mobility, and radio channel conditions, enabling the system to adapt to dynamic environments while maintaining high reliability.
Solution Approach 2:
The patent implements feedback mechanisms where terminal devices report status information including measurements to network devices, which then provide this information to the network controller. The network controller uses this feedback to determine coordination policies and dynamically adjust RG configurations, ensuring optimal redundancy allocation based on actual network state.
2Adaptability or versatility
If multiple terminal devices are grouped together in a static RG, then device management is simplified, but the system cannot adapt to varying cell load, terminal mobility, and radio channel conditions
Solution Approach 1:
The system dynamically adjusts RG assignments based on real-time conditions including cell load, terminal mobility, and radio channel quality. Terminal devices can be reassigned to different RGs or network devices as conditions change, enabling the system to adapt to dynamic environments while maintaining management efficiency through centralized coordination.
Solution Approach 2:
The patent changes key parameters such as RG configuration, terminal device assignment, and redundancy allocation based on measured network conditions. The network controller adjusts these parameters in response to feedback from terminal devices, optimizing the balance between adaptability and management complexity.
3Reliability
If redundant user plane paths are configured without dynamic coordination, then the configuration process is simple, but the diversity and redundancy degree are not optimized
Solution Approach 1:
The network controller serves as an intermediary that coordinates between terminal devices and network devices. It receives status information from terminals and network devices, processes this information to determine optimal coordination policies, and assigns redundant user plane paths. This intermediary role enables optimized redundancy configuration without requiring direct complex interactions between all network elements.
Solution Approach 2:
The system uses feedback loops where terminal devices provide measurements and status information to network devices, which then report to the network controller. This feedback enables the controller to make informed decisions about redundancy configuration, optimizing the diversity and redundancy degree based on actual network conditions rather than using fixed pre-configured paths.
