Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electronic devices face challenges in efficiently managing attach failures and errors when transitioning between cells, particularly in environments with complex network structures, leading to suboptimal network performance.
Innovation Solution
The electronic device identifies attach failure rates and adjusts its UE capability by decreasing the size of the UE capability when necessary, and transmits adjusted capabilities to a second cell, or adjusts and transmits a pre-stored capability based on error detection in neighboring cells.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the electronic device transmits full UE capability information to all cells, then the network can make accurate handover decisions, but the signaling overhead and processing complexity increase
Solution Approach 1:
The patent applies local quality by transmitting different amounts of UE capability information to different cells based on their specific characteristics. The device determines whether to transmit full capability information or reduced information based on cell-specific factors such as cell type, handover frequency, and network configuration, thereby optimizing the balance between decision accuracy and signaling overhead for each individual cell interaction
Solution Approach 2:
The patent implements partial action by selectively transmitting only the necessary portion of UE capability information to each cell rather than always transmitting the complete capability set. The device evaluates whether full capability information is needed for each specific cell scenario, and transmits reduced capability information when full information is not required, thus reducing signaling overhead while maintaining sufficient decision-making capability
2Reliability
If the electronic device adjusts UE capability size based on attach failure rates, then network stability improves, but the device complexity increases due to continuous monitoring and adjustment
Solution Approach 1:
The patent applies feedback by continuously monitoring attach failure rates and using this information to adjust UE capability size. The device receives feedback from the network about attach success/failure, analyzes the failure rate patterns, and dynamically adjusts the capability information transmitted to cells accordingly. This closed-loop feedback mechanism improves network stability by adapting to actual network conditions while managing device complexity through systematic decision-making rules
Solution Approach 2:
The patent implements dynamics by making the UE capability size adjustable rather than fixed. The device dynamically changes the amount of capability information transmitted based on real-time attach failure rate measurements and network conditions. This dynamic adaptation allows the system to respond to changing network states, improving stability while the structured adjustment process manages the complexity of capability management
3Measurement precision
If the electronic device transmits detailed error information from neighboring cells, then network optimization accuracy improves, but the information processing load and transmission overhead increase
Solution Approach 1:
The patent applies the extraction principle by selectively extracting and transmitting only the most relevant error information from neighboring cells rather than transmitting all available measurement data. The device identifies key error indicators that are most useful for network optimization decisions and transmits only those specific parameters, thereby maintaining high detection accuracy while significantly reducing the volume of information that needs to be processed and transmitted
