Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In high-speed scenarios, user equipment (UE) experiences undesirable wireless conditions, leading to unnecessary wireless network handovers, which can result in access failures and network overload due to inappropriate barred times in resource management protocols.
Innovation Solution
A method and apparatus that dynamically adjust the barred time for a moving UE based on its dynamic characteristics, such as speed and signal strength, to minimize handovers and maintain access to a dedicated wireless network by applying the adjusted barred time to the resource management protocol.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the barred time is set to a fixed value in resource management protocols, then the protocol implementation is simple, but in high-speed scenarios this leads to unnecessary handovers and access failures
Solution Approach 1:
The patent implements dynamic adjustment of barred time based on UE movement characteristics. The system transitions from a static fixed barred time to a dynamic value that adapts to UE speed and signal conditions, thereby improving access reliability in high-speed scenarios while managing the increased complexity through structured adjustment mechanisms
Solution Approach 2:
The patent changes the parameter of barred time from a fixed constant to a variable that is adjusted based on measured signal strength variations and UE speed. This parameter transformation allows the system to adapt to different mobility scenarios, preventing unnecessary handovers in high-speed cases while maintaining appropriate access control in other scenarios
2Stability of the object's composition
If the barred time is reduced to prevent handovers in high-speed scenarios, then network stability is improved, but access failures may occur due to insufficient access attempts
Solution Approach 1:
The system dynamically adjusts barred time based on real-time UE speed and signal conditions. In high-speed scenarios with stable signal, the barred time is reduced to maintain connection stability, while in other scenarios it is increased to allow sufficient access attempts, thus balancing stability and reliability
Solution Approach 2:
The barred time parameter is transformed from a fixed value to a condition-dependent variable. The system measures signal strength variations and UE speed to determine the appropriate barred time value, ensuring that access success rate is maintained while preventing unnecessary handovers in high-speed stable scenarios
3Reliability
If the UE attempts frequent access in high-speed scenarios, then access success probability increases, but network overload occurs due to excessive handovers
Solution Approach 1:
The system applies preliminary anti-action by detecting high-speed scenarios and proactively adjusting the barred time to prevent excessive access attempts before they occur. This anticipatory adjustment blocks unnecessary handover attempts that would otherwise cause network overload, while still allowing legitimate access when needed
Solution Approach 2:
The barred time parameter is dynamically modified based on UE speed measurements. In high-speed scenarios, the parameter is adjusted to limit access frequency, preventing network overload while maintaining adequate access success rate for legitimate communication needs
4Adaptability or versatility
If the barred time is adjusted dynamically based on UE characteristics, then access optimization is achieved, but the resource management protocol complexity increases
Solution Approach 1:
The patent introduces dynamic adjustment mechanisms that adapt the barred time to UE mobility conditions. This increases adaptability by allowing the system to respond to different speed scenarios, while the complexity is managed through structured measurement and adjustment procedures integrated into the existing resource management framework
Solution Approach 2:
The system implements parameter changes by making the barred time variable based on measured UE characteristics. This enhances adaptability to different mobility scenarios while controlling protocol complexity through systematic parameter adjustment based on measurable physical quantities like signal strength variation and speed
