UE Idle Mode Mobility Measurement Thresholds
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mobile communication networks face challenges in idle mode mobility measurements, where static threshold settings in SIB messages lead to excessive battery consumption, decreased serving cell quality, and increased likelihood of UE being unreachable due to manual and costly configuration processes, lacking adaptability to changing conditions.
Innovation Solution
User Equipment (UE) configures idle mode mobility measurement thresholds using internal algorithms, measuring cell quality parameters and calculating updated thresholds for dynamic adjustments, allowing for UE-configured parameter settings that adapt to changing conditions and optimize battery life and serving cell quality.

1Device complexity
If static threshold settings are used in SIB messages for idle mode mobility measurements, then network configuration is simplified, but battery consumption increases and serving cell quality decreases
Solution Approach 1:
The patent applies dynamics by transitioning from static threshold settings to dynamic threshold adjustment. The network node collects measurement results from multiple UEs and automatically updates thresholds based on aggregated data, allowing the system to adapt to changing network conditions while reducing unnecessary measurements and battery consumption.
Solution Approach 2:
The patent implements feedback mechanisms where measurement results from UEs are collected by the network node, processed, and used to update thresholds. This closed-loop feedback system enables continuous optimization of measurement parameters based on actual network performance, balancing quality of service with energy consumption.
2Duration of action of moving object
If high threshold values are set for idle mode mobility measurements, then battery life is extended, but serving cell quality decreases and re-selection is delayed
Solution Approach 1:
The patent applies parameter changes by dynamically adjusting measurement thresholds based on aggregated measurement data from multiple UEs. The system modifies threshold values within defined ranges (e.g., ±3 dB) to optimize the balance between battery life and serving cell quality, allowing adaptive response to changing network conditions without manual reconfiguration.
Solution Approach 2:
The patent implements partial action by selectively triggering measurements only when necessary conditions are met. The system uses aggregated measurement results to determine when threshold updates are needed, avoiding excessive measurements while ensuring quality of service is maintained through targeted adjustments.

If manual configuration of measurement parameters is performed, then network optimization can be achieved, but time and cost increase significantly
Solution Approach 1:
The patent applies self-service by enabling the network to automatically optimize measurement parameters without manual intervention. The system collects measurement data from UEs, processes it through the network node, and automatically updates thresholds based on aggregated results, eliminating the need for costly and time-consuming field tests while maintaining network performance.

AI summary
Methods, apparatus and articles of manufacture for performing idle mode mobility measurements in a mobile network are disclosed. An example method in a user equipment (UE) disclosed herein comprises receiving, from the mobile network, a system information block (SIB) message specifying idle mode mobility measurement is to be performed. If the measurement parameter threshold is not configured in the SIB message or if the SIB message includes an indication to not use a configured measurement parameter threshold in the SIB message, the UE sets a measurement parameter threshold for idle mode mobility measurement.
