Network UE Paging Deferral for Poor Propagation Channels

Solution Overview

Problem

Wireless communication networks face challenges in efficiently managing power consumption and resource usage for user equipment (UE) in areas with poor coverage, particularly when UE is required to respond promptly to paging messages, leading to increased energy consumption and potential network resource escalation.

Innovation Solution

The UE paging process is delayed in the network at core or radio access network (RAN) nodes based on historical and current propagation channel characteristics, allowing for efficient postponement of data downloads until channel conditions improve, reducing power consumption and resource usage.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of energy

If the UE responds promptly to paging messages, then the network resource escalation is avoided, but the power consumption increases due to poor channel conditions

Engineering Contradiction:

Improvepower consumptionVSAvoidresponse delay

Core Design Contradiction:

Loss of energyVSLoss of time

Solution Approach 1:

The network performs preliminary assessment of channel conditions before initiating paging operations. By evaluating propagation channel characteristics in advance, the system can determine whether to delay paging, thereby avoiding unnecessary power consumption at the UE while preventing network resource escalation through proactive decision-making

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system implements feedback mechanisms where channel quality indicators are continuously monitored and fed back to the paging decision logic. This allows the network to adaptively adjust paging timing based on real-time channel conditions, balancing UE power consumption with response timeliness

Inventive Principle:

Principle #23Feedback

2Loss of energy

If the UE delays paging response to reduce power consumption, then energy efficiency improves, but network resource escalation occurs

Engineering Contradiction:

Improvepower consumptionVSAvoidnetwork resource usage

Core Design Contradiction:

Loss of energyVSDevice complexity

Solution Approach 1:

The network performs preliminary assessment of channel conditions before initiating paging operations. By evaluating propagation channel characteristics in advance, the system can determine whether to delay paging, thereby avoiding unnecessary power consumption at the UE while preventing network resource escalation through proactive decision-making

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system implements feedback mechanisms where channel quality indicators are continuously monitored and fed back to the paging decision logic. This allows the network to adaptively adjust paging timing based on real-time channel conditions, balancing UE power consumption with response timeliness

Inventive Principle:

Principle #23Feedback

3Productivity

If data download is delayed until channel conditions improve, then data rate increases, but the communication time increases

Engineering Contradiction:

Improvedata rateVSAvoidcommunication time

Core Design Contradiction:

ProductivityVSLoss of time

Solution Approach 1:

The system changes the timing parameter of paging operations based on channel conditions. By dynamically adjusting when paging occurs rather than changing the data rate itself, the system avoids the trade-off between data rate and communication time, as the actual data transfer happens at optimal channel conditions without extending overall communication time

AI summary

A method of operating a network node includes receiving a request to trigger a paging procedure based on receipt of downlink data in a core network from an application server (AS) and determining, responsive to receiving the request to trigger the paging procedure, whether to delay paging of a user equipment (UE) based on characteristics of a propagation channel for data communication associated with the UE.
