Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
During communication between multi-card user equipment and network devices, switching between different service networks causes service interruptions, affecting communication quality.
Innovation Solution
A method where user equipment sends auxiliary information to a network device to receive first measurement gap configuration information, allowing the network device to determine and send configuration details for seamless switching, including measurement gap times, enabling service transmission during non-measurement periods.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If user equipment performs cell and neighboring cell measurements under the target network when switching from service network to target network, then measurement accuracy is improved, but service interruption under the service network increases
Solution Approach 1:
The network device pre-configures measurement gap information to the user equipment before the actual network switching occurs. This preliminary configuration includes setting up measurement gaps in advance, allowing the UE to perform measurements during these pre-arranged gaps without causing service interruption, as the gaps are planned and coordinated with the service network's scheduling
Solution Approach 2:
The measurement process is segmented into specific time gaps (measurement gaps) separated from service transmission times. During measurement gaps, the UE performs measurements on target network cells, while during non-gap periods, normal service transmission continues uninterrupted. This temporal segmentation allows both measurement and service functions to operate independently without mutual interference
2Adaptability or versatility
If user equipment switches from service network to target network for measurements, then network adaptability is improved, but communication quality deteriorates due to service interruption
Solution Approach 1:
The network device (source or target) acts as an intermediary that coordinates the measurement process. It provides measurement gap configuration information to the UE and coordinates with both service and target networks to ensure measurements occur at appropriate times that minimize impact on service communication quality
Solution Approach 2:
The measurement gap configuration is dynamically adjusted based on the specific switching scenario. The network device can configure different measurement gap patterns, durations, and timings according to the UE's switching needs and the service network's requirements, allowing flexible adaptation while maintaining communication quality
