Measurement Window Scheduling to Avoid Mobile Communication Interruptions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Mobile devices experience communication interruptions when measuring neighboring cells operating at different frequencies, necessitating suspension of communication with the serving cell, which affects network connectivity and latency.
Innovation Solution
Implementing a system where the network indicates time windows during which communication interruptions for measurements are avoided, allowing uninterrupted communication by either skipping or rescheduling measurement occasions based on dynamic or semi-static indications.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the mobile device measures neighboring cells at different frequencies by suspending communication with the serving cell, then measurement capability is improved, but communication continuity deteriorates
Solution Approach 1:
The network device pre-configures measurement objects and determines measurement windows in advance, allowing the terminal to perform measurements during pre-allocated time periods without disrupting ongoing communications. This preliminary planning enables measurements to be performed without causing communication interruptions.
Solution Approach 2:
The measurement configuration is made dynamic through time-window-based indications. The network can dynamically adjust measurement windows based on communication requirements, and the terminal adapts its measurement schedule accordingly. This dynamic approach allows the system to balance measurement needs with communication continuity.
2Measurement precision
If the mobile device suspends communication to perform measurements on different frequencies, then measurement accuracy is improved, but communication latency increases
Solution Approach 1:
The network device determines measurement windows and notifies the terminal in advance, allowing measurements to be performed during pre-allocated time periods. This ensures measurements are conducted without disrupting ongoing communications, thereby maintaining both measurement accuracy and communication latency performance.
Solution Approach 2:
The system enables continuous communication by performing measurements during specifically designated measurement windows rather than suspending communication. The terminal maintains continuous connection with the serving cell while periodically tuning to measurement frequencies during allocated time slots, ensuring uninterrupted data transmission and reception.
3Device complexity
If the mobile device uses a single RF module for all measurements and communications, then device complexity is reduced, but measurement flexibility deteriorates
Solution Approach 1:
The system implements dynamic frequency tuning of the single RF module based on time-window indications from the network. The terminal can flexibly switch between serving cell frequency and measurement frequencies by receiving dynamic configuration updates, achieving measurement flexibility comparable to multiple RF modules while maintaining device simplicity.

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.
