Multi-Identity UE Cell Reselection Measurement Optimization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In communication networks, multi-card terminals face high power consumption due to independent cell reselection measurements by each identity recognition module, which is inefficient and wasteful.
Innovation Solution
Configuring measurement instruction information for user equipment (UE) with multiple identity recognition modules to selectively perform cell reselection measurements based on signal strength conditions, allowing one module to perform measurements when signal strengths are high and all modules to measure independently when signal strengths are low, thereby reducing unnecessary power usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If each identity recognition module independently performs cell reselection measurement, then measurement accuracy is improved, but power consumption increases
Solution Approach 1:
The patent applies partial action by having only one identity recognition module perform cell reselection measurement when signal conditions are good, rather than requiring all modules to measure independently. This reduces power consumption while maintaining adequate measurement accuracy for the UE's communication needs.
Solution Approach 2:
The patent changes the measurement behavior parameter based on signal strength conditions. When reference signal received power exceeds a threshold, the system switches from independent measurement by all modules to shared measurement by one module, dynamically adjusting measurement behavior to balance accuracy and power consumption.
2Reliability
If all identity recognition modules perform independent cell reselection measurement, then measurement reliability is improved, but system complexity increases
Solution Approach 1:
The patent reduces complexity by implementing partial measurement action - only one module performs measurement when conditions permit, simplifying the coordination mechanism while maintaining reliability through conditional independent measurement when signal conditions are poor.
3Use of energy by moving object
If one identity recognition module performs cell reselection measurement, then power consumption is reduced, but measurement accuracy decreases
Solution Approach 1:
The patent dynamically changes measurement behavior based on signal strength parameters. When reference signal received power is above a threshold, one module measures to save power; when below the threshold, all modules measure independently to ensure accuracy, thus adapting measurement precision to actual signal conditions.

AI summary
An information processing method is provided. The method includes: configuring, for a user equipment (UE), measurement indication information used for cell reselection, where the UE has at least two identity recognition modules; and sending the measurement indication information to the UE, where the measurement indication information includes: first measurement indication information; and the first measurement indication information is used for indicating that the UE uses, when meeting a first condition, one identity recognition module from among the at least two identity recognition modules to perform cell reselection measurement.
