Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems face challenges in efficiently prioritizing interlayer searches and measurements based on user equipment (UE) mobility, leading to suboptimal resource allocation and power consumption in mobile environments.
Innovation Solution
The method involves prioritizing the periodicity of interlayer searches and measurements based on the priority of the layer to be measured and the level of UE mobility, using a sensor module to determine mobility levels and adjust measurement frequencies accordingly, thereby optimizing resource allocation and power conservation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If interlayer searches and measurements are performed frequently to ensure reliable handover, then handover reliability is improved, but power consumption increases
Solution Approach 1:
The patent applies dynamics by adjusting measurement periodicity based on UE mobility state. The system transitions from static measurement scheduling to dynamic scheduling that responds to mobility conditions. When UE mobility is detected as high, measurement periodicity is increased to ensure reliable handover. When mobility is low, measurement periodicity is reduced to save power. This dynamic adaptation resolves the contradiction between handover reliability and power consumption.
Solution Approach 2:
The patent changes the parameter of measurement periodicity based on mobility level. By modifying this temporal parameter dynamically, the system achieves different measurement frequencies according to actual network conditions. High mobility triggers more frequent measurements for reliability, while low mobility allows less frequent measurements for power conservation, thus resolving the technical contradiction.
2Reliability
If measurement periodicity is increased to improve handover performance, then handover performance is improved, but power consumption increases
Solution Approach 1:
The system implements dynamic measurement periodicity adjustment based on real-time mobility detection. The measurement scheduling mechanism adapts its frequency according to whether the UE is moving quickly or slowly, ensuring optimal handover performance when needed while minimizing power consumption during stable conditions.
Solution Approach 2:
The patent utilizes periodic action by implementing measurement cycles that vary in frequency. Instead of continuous or fixed-periodic measurements, the system employs variable-periodic measurements where the period length changes based on mobility state. This allows the system to perform measurements only when necessary, reducing overall power consumption while maintaining handover performance.
3Quantity of substance
If all layers are measured with equal priority, then measurement completeness is improved, but processing time increases
Solution Approach 1:
The patent segments the measurement task by prioritizing different layers based on mobility conditions. Instead of treating all layers equally, the system divides measurements into high-priority and low-priority categories. When mobility is high, higher layers are measured more frequently. When mobility is low, lower layers are measured less frequently. This segmentation allows the system to maintain measurement completeness for critical layers while reducing processing time for less critical layers.
Solution Approach 2:
The patent applies local quality by assigning different measurement priorities to different layers based on their relevance to current mobility conditions. Not all layers require equal measurement frequency - the system locally optimizes measurement intensity for each layer according to its importance for handover decisions, thereby reducing overall processing time while maintaining necessary measurement completeness.

AI summary
A user equipment (UE) prioritizes searches and/or measurements of neighbor cells/frequencies based on a level of mobility of a UE. In one instance, the UE identifies a priority of a layer of a radio access technology (RAT) to be measured or searched and identifies a level of mobility of the UE. A sensor module of the UE may determine the level of mobility of the UE and generate an indication corresponding to the level of mobility of the UE. The UE prioritizes a periodicity of interlayer search and/or measurement based on the priority of the layer to be measured and the level of the mobility of the UE.
