Merged DRX Schedules for Paging Signal Convergence
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current Discontinuous Reception (DRX) methods in mobile radio communication devices, particularly for Machine Type Communications (MTC), face challenges with extended DRX cycles, leading to missed paging signals due to simultaneous convergence of access requests and power consumption issues.
Innovation Solution
Implementing a merged schedule of planned DRX activity across multiple MTC applications and servers, allowing for coordinated receiver activation during scheduled paging times to prevent signal overlap and enhance power saving.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If the DRX cycle is extended to reduce power consumption, then energy saving is improved, but the risk of missing paging signals increases due to simultaneous access requests from multiple servers
Solution Approach 1:
The device performs preliminary actions by calculating and determining multiple DRX schedules in advance, corresponding to different MTC applications and servers. These schedules are computed before the actual paging reception occurs, allowing the device to proactively plan its receiver activation times to avoid missing any paging signals while maintaining extended DRX cycles for power savings.
Solution Approach 2:
The invention segments the single DRX cycle into multiple distinct DRX schedules, each tailored to specific MTC applications or servers. By dividing the monitoring task into separate schedules with different timing parameters, the device can systematically manage receiver activation for each application, preventing signal convergence issues while maintaining extended power-saving cycles.
2Adaptability or versatility
If multiple MTC applications use separate DRX cycles independently, then each application can be monitored individually, but signal overlap and convergence occur leading to missed paging messages
Solution Approach 1:
The invention merges multiple independent DRX schedules into a unified coordinated monitoring approach. By calculating all DRX schedules and identifying their combined monitoring occasions, the device consolidates receiver activation times to ensure all paging signals from different applications are captured without overlap or convergence, preventing information loss while maintaining multi-application support.
3Reliability
If the receiver is activated frequently to ensure no paging signals are missed, then reliability is improved, but power consumption increases
Solution Approach 1:
The invention implements periodic action by establishing regular, predetermined DRX schedules for each MTC application with specific cycle lengths and monitoring occasions. Instead of continuous or ad-hoc receiver activation, the device follows structured periodic patterns that ensure reliable paging signal reception at predetermined intervals while minimizing unnecessary receiver activation to conserve power.
