Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If user equipment performs measurements on multiple networks simultaneously, then network performance and connection reliability are improved, but measurement collisions occur causing resource conflicts and operational complexity
Solution Approach 1:
The patent segments measurement configurations into different types (first measurement configurations for first network, second MG configurations for second network) and assigns priorities to each segment. This allows the UE to manage multiple measurement tasks by processing them in prioritized segments, resolving collisions systematically without overwhelming the device.
Solution Approach 2:
The network device performs preliminary action by configuring measurement parameters and priorities before measurements occur. The UE receives measurement configuration information that pre-establishes the priority order and collision resolution rules, allowing the UE to handle measurement collisions efficiently without complex real-time decision-making.
2Measurement precision
If measurement gap configurations are optimized for multiple networks, then measurement accuracy is improved, but measurement collisions increase causing lower-priority measurements to be dropped
Solution Approach 1:
The patent applies preliminary anti-action by pre-establishing priority rules and collision resolution mechanisms before measurement collisions occur. When collisions are detected, the UE can immediately identify which measurements should be dropped based on pre-configured priorities, preventing unnecessary measurement failures while maintaining accuracy for high-priority measurements.
Solution Approach 2:
The patent changes parameters such as measurement timing, gap configurations, and priority levels to optimize measurement accuracy while managing collisions. By adjusting these parameters dynamically or statically, the system can ensure that critical measurements are performed accurately while lower-priority measurements are scheduled during non-conflicting time windows.
3Productivity
If the UE manages multiple measurement configurations without prioritization, then all measurements are attempted simultaneously, but measurement collisions cause resource waste and operational failures
Solution Approach 1:
The patent introduces dynamic priority management where the UE can adjust measurement priorities based on real-time conditions and network requirements. This dynamic approach allows the system to optimize measurement efficiency by shifting resources to critical measurements when needed while avoiding collisions with lower-priority measurements during optimal time windows.
Solution Approach 2:
The system implements feedback mechanisms where the UE reports measurement status and collision detection to the network device. This feedback loop allows for continuous optimization of measurement configurations, enabling the network to adjust priorities and timing to prevent collisions and improve overall measurement efficiency.

AI summary
A measurement method includes: receiving measurement configuration information sent by a network device, the measurement configuration information including N sets of measurement configurations, the N sets of measurement configurations including M sets of first measurement configurations and N-M sets of second measurement gap (MG) configurations, the first measurement configurations being used for performing measurement on a first network, the second MG configurations being used for performing MG-based measurement on a second network, and the first network being a network to which the network device belongs; determining, in response to presence of a measurement collision in the N sets of measurement configurations, based on priorities of the N sets of measurement configurations with the measurement collision, not performing measurement corresponding to K sets of measurement gap configurations with a lower priority in the N sets of measurement configurations with the measurement collision.
