Mobile RF Measurement Windows to Avoid Communication Interruptions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Mobile devices experience communication interruptions when measuring neighboring cells operating at different frequencies or radio access technologies due to the need to suspend communication with the serving cell, causing network disconnection and increased latency.
Innovation Solution
Implementing a system where a network device sends information to a mobile device to avoid communication interruptions by indicating a time window during which measurements can be performed without interruptions, allowing the device to adjust its RF tuning accordingly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the mobile device performs measurements on neighboring cells operating at different frequencies or radio access technologies, then the measurement capability is improved, but communication interruption occurs
Solution Approach 1:
The network device pre-configures measurement windows and provides measurement configurations to the mobile device in advance. The mobile device performs measurements during pre-defined measurement windows, allowing the network to schedule communication activities around these measurement periods, thereby reducing unexpected interruptions
Solution Approach 2:
The measurement configuration is made dynamic and adjustable. The network device can modify measurement window positions, durations, and frequencies based on current communication conditions. The mobile device can also provide feedback about measurement needs, creating a dynamic adaptation mechanism that balances measurement requirements with communication continuity
2Measurement precision
If the mobile device suspends communication with the serving cell to perform measurements, then the measurement accuracy is improved, but communication latency increases
Solution Approach 1:
The measurement process is segmented into specific measurement windows rather than continuous suspension. The mobile device performs measurements only during designated time intervals, allowing communication to continue during non-measurement periods. This segmentation reduces the total time lost to measurements while maintaining measurement accuracy through focused measurement efforts
Solution Approach 2:
Measurements are performed periodically during configured measurement windows rather than continuously suspending communication. The periodic measurement approach allows the system to balance measurement needs with communication requirements, reducing overall latency while maintaining measurement capabilities through regular periodic measurements
3Device complexity
If the mobile device uses a single RF module for all measurements and communications, then the device complexity is reduced, but measurement flexibility is limited
Solution Approach 1:
The network device provides detailed measurement configurations in advance, including measurement window timings, frequency information, and measurement object details. This preliminary configuration allows a single RF module to efficiently switch between frequencies and measurement tasks without requiring complex real-time decision-making circuitry in the mobile device
Solution Approach 2:
The network device acts as an intermediary that manages the complexity of measurement coordination. By providing centralized measurement configuration and scheduling, the network device enables a simple single-RF-module mobile device to perform flexible measurements across multiple frequencies and radio access technologies without requiring complex local measurement management

AI summary
Example embodiments of the present disclosure are directed to methods, devices, apparatuses and computer readable storage medium for interruption avoidance. In the method, a first apparatus receives, from a second apparatus, information for disallowing a communication interruption associated with a measurement. Moreover, the first apparatus handles respective measurements on one or more measurement objects based on the received information and object information. The object information at least indicates whether the one or more measurement objects cause a communication interruption. Thereby, the proposed solution can advantageously avoid additional delay that may be caused by interruptions.
