Paging Early Indication Offset Value Selection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current paging mechanisms in wireless communication networks incur high signaling overhead and power consumption due to the need for terminal devices to continuously monitor for paging messages, even when not actively connected, which is inefficient for devices with varying paging cycles and capabilities.
Innovation Solution
The solution involves selecting a pre-defined offset value based on the configured paging cycle of a terminal device to determine a time offset between a paging early indication (PEI) and a paging occasion, allowing the device to monitor for the PEI on a specific time occasion and reducing unnecessary monitoring.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If terminal devices continuously monitor for paging messages, then paging reliability is improved, but power consumption increases
Solution Approach 1:
The patent implements discontinuous reception where terminal devices alternate between sleeping and waking up to monitor paging messages at periodic intervals defined by DRX cycles. This periodic monitoring approach maintains paging reliability by ensuring devices check for messages at regular intervals while dramatically reducing power consumption compared to continuous monitoring.
2Loss of time
If terminal devices monitor paging occasions frequently, then paging response time is improved, but signaling overhead increases
Solution Approach 1:
The patent employs dynamic DRX cycle adjustment where the network can configure different DRX cycle lengths based on terminal device activity patterns and service requirements. This dynamic configuration allows the system to optimize between fast paging response (shorter cycles) and reduced signaling overhead (longer cycles) depending on current network conditions and device needs.
3Device complexity
If uniform paging cycles are used for all terminal devices, then system complexity is reduced, but adaptability decreases
Solution Approach 1:
The patent enables each terminal device to have customized DRX cycle configurations tailored to its specific service requirements, device capabilities, and activity patterns. The network can assign different DRX parameters to different devices or device groups, allowing optimal power saving and response time for each device type while maintaining a standardized base protocol that limits overall system complexity.

AI summary
Disclosed is a method comprising selecting, based on one or more criteria, at least one offset value from a set of at least two pre-defined offset values, wherein the selected at least one offset value indicates a time offset between a paging early indication and a paging occasion; and transmitting, to at least one terminal device, the paging early indication on at least one time occasion indicated by the selected at least one offset value.
