Multi-USIM Measurement Prioritization Under Network Resource Conflicts
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
When a terminal device with multiple universal subscriber identity modules (USIMs) accesses multiple networks simultaneously, resource conflicts occur, leading to measurement interruptions and impaired communication due to conflicting hardware resource usage, affecting network state changes and mobility.
Innovation Solution
The terminal device cancels measurements on conflicting resources and sends indication information to the network, allowing the network to reconfigure measurement objects based on priority, ensuring uninterrupted data transmission in the secondary network.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the terminal device measures multiple measurement objects in the first network, then the mobility measurement coverage is improved, but resource conflicts occur with the second network causing measurement interruptions
Solution Approach 1:
The patent implements dynamic measurement object management by allowing the terminal device to adjust measurement configurations based on real-time resource availability. When resource conflicts are detected between networks, the terminal dynamically cancels or prioritizes specific measurement objects, transforming the static measurement configuration into an adaptive system that responds to changing network conditions.
Solution Approach 2:
The patent changes the state of measurement objects by introducing priority levels and enable/disable flags. The network can modify measurement object parameters (such as setting them as essential or non-essential) to control which measurements continue during resource conflicts, effectively using parameter changes to resolve the contradiction between comprehensive measurement coverage and measurement reliability.
2Device complexity
If the terminal device shares hardware resources across multiple networks, then device complexity is reduced, but resource conflicts cause measurement failures
Solution Approach 1:
The patent segments the measurement resource pool into priority-based groups (essential measurements vs. non-essential measurements). This segmentation allows the terminal device to selectively maintain critical measurements while suspending non-critical ones during resource conflicts, ensuring measurement reliability without requiring separate hardware for each network.
Solution Approach 2:
The patent introduces an intermediary mechanism (the measurement object configuration with priority indicators) that mediates between multiple networks competing for shared hardware resources. The network devices use this intermediary configuration to coordinate their resource usage, allowing the terminal to manage shared hardware without measurement failures.
3Reliability
If the terminal device cancels measurement on conflicting resources, then communication reliability in the second network is improved, but measurement coverage in the first network is reduced
Solution Approach 1:
The patent applies local quality by treating different measurement objects differently based on their priority and importance. Instead of uniformly canceling all measurements during resource conflicts, the terminal selectively maintains essential measurements (local quality preservation) while canceling non-essential ones, thus preserving communication reliability in the second network while maintaining necessary measurement capabilities in the first network.

AI summary
This application provides a measurement method and an apparatus. The method includes: A terminal device receives a first measurement configuration from a first network device in a first network, where the first measurement configuration indicates to measure the M measurement objects, and M is an integer greater than 0. The terminal device may cancel measurement on at least one of the M measurement objects, where a resource used to measure the at least one measurement object conflicts with a resource used by the terminal device in a second network. According to the foregoing method, when the first network indicates, to the terminal device, the M measurement objects that need to be measured, the terminal device determines that there is a measurement object in the M measurement objects that has a resource conflict with the second network. Consequently, when these measurement object configurations cannot be normally measured, the terminal device may cancel the measurement on these measurement objects, to avoid impact of the measurement objects on data transmission in the second network.
