Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

User Equipment (UE) in areas of poor coverage consumes excessive power due to poor communication channel quality, leading to increased battery drain, and existing methods of delaying paging responses can inefficiently escalate network paging resources and power consumption.

Innovation Solution

The UE paging process is delayed in the network based on historical and current propagation channel characteristics, allowing for efficient postponement of data downloads until channel conditions improve, reducing energy consumption and conserving network resources.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of time

If the UE transmits data immediately in poor coverage conditions, then the data transmission can proceed without delay, but the UE power consumption increases significantly

Engineering Contradiction:

Improvedata transmission delayVSAvoidUE power consumption

Core Design Contradiction:

Loss of timeVSUse of energy by moving object

Solution Approach 1:

The network performs preliminary assessment of propagation channel characteristics before initiating paging. By evaluating historical and current channel quality indicators in advance, the network can determine whether channel conditions are suitable for data transmission, thereby avoiding immediate transmission in poor conditions that would cause excessive power consumption.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The paging delay decision is dynamic rather than static. The network continuously monitors propagation channel characteristics and adjusts the paging timing based on real-time channel conditions. This dynamic approach allows the system to optimize between transmission delay and power consumption by adapting to changing channel quality.

Inventive Principle:

Principle #15Dynamics

2Reliability

If the network escalates paging to wider area when UE does not respond, then the network can ensure delivery to mobile UEs, but network paging resources are consumed inefficiently

Engineering Contradiction:

Improvedata delivery reliabilityVSAvoidnetwork paging resource consumption

Core Design Contradiction:

ReliabilityVSLoss of energy

Solution Approach 1:

The network performs preliminary evaluation of propagation channel characteristics before escalating paging to wider areas. By assessing channel conditions in advance, the network can distinguish between UEs that are temporarily unable to respond due to poor channels versus UEs that have left the coverage area, thereby avoiding unnecessary wide-area paging escalations and conserving network resources.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system uses feedback from propagation channel characteristic assessments to make intelligent paging decisions. By continuously monitoring channel quality indicators and using this feedback to adjust paging strategies, the network can improve data delivery reliability while reducing unnecessary paging resource consumption through more accurate targeting.

Inventive Principle:

Principle #23Feedback

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.
