Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In 5G mobile communication systems, the increased UE radio capability leads to inefficiencies in message transmission due to the need for more complex radio resource management, as the existing systems struggle to fully utilize the enhanced capabilities, resulting in resource wastage and inefficiencies.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If UE radio capability information is fully transmitted in one message, then complete capability information is provided to the core network, but message size increases and radio resource efficiency decreases
Solution Approach 1:
The UE radio capability information is segmented into multiple parts: a first message containing essential capability information for initial network operations, and a second message containing detailed capability information for advanced features. This segmentation allows the core network to receive complete capability information while optimizing radio resource usage by transmitting only essential information in the first message.
Solution Approach 2:
The patent implements preliminary transmission of essential UE radio capability information in the first message before the UE fully utilizes all radio resources. This preliminary action enables the core network to perform initial capability-based decisions without waiting for complete capability information, thereby improving resource allocation efficiency while maintaining information completeness through the subsequent second message.
2Adaptability or versatility
If UE radio capability increases to support more band combinations and functions, then system functionality is enhanced, but message size and processing complexity increase
Solution Approach 1:
The patent segments UE radio capability information into hierarchical levels: basic capabilities in the first message and advanced capabilities (such as band combinations, MIMO configurations, and feature-specific parameters) in the second message. This segmentation reduces the complexity of initial message processing while maintaining full adaptability by transmitting detailed capability information when needed.
Solution Approach 2:
The patent applies local quality by transmitting different levels of capability information quality at different stages: the first message contains high-quality essential information for critical operations, while the second message provides detailed quality information for optional advanced features. This approach enhances system functionality without proportionally increasing overall message complexity.
3Speed
If essential UE radio capability information is transmitted first, then core network can make initial decisions quickly, but complete capability information may be delayed
Solution Approach 1:
The patent implements preliminary transmission of essential UE radio capability information in the first message, enabling the core network to make initial decisions about resource allocation, access control, and basic service provisioning without waiting for complete capability information. The second message subsequently provides the remaining detailed capability information, ensuring no information loss while maintaining fast initial response.
Solution Approach 2:
The patent establishes a feedback mechanism where the core network receives the first message, makes initial decisions, then requests additional detailed capability information in the second message if needed for specific operations. This feedback loop ensures that the core network maintains decision-making speed while ultimately receiving complete capability information for optimized resource management.
