Solution Overview

Problem

Existing mobile wireless communication systems face challenges in managing varying resource demands and energy efficiency, particularly in handling different quality-of-service classes like URLLC, eMBB, and mMTC, which impact network load and energy consumption.

Innovation Solution

A method involving a radio network node that determines low-usage paging occasions and delegates paging to other occasions, allowing user equipment to enter a low-power state, thereby optimizing energy usage and maintaining communication efficiency.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If paging is continuously monitored at all paging occasions, then communication reliability is maintained, but energy consumption increases

Engineering Contradiction:

Improvecommunication reliabilityVSAvoiduser equipment energy consumption

Core Design Contradiction:

ReliabilityVSUse of energy by moving object

Solution Approach 1:

The patent implements dynamic paging monitoring by allowing user equipment to switch between monitoring all paging occasions and monitoring only delegated paging occasions based on received indications from the network. This dynamic adjustment enables the system to adapt monitoring behavior to actual network conditions, reducing energy consumption when full monitoring is not necessary while maintaining reliability when needed.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The patent changes the paging monitoring parameter state by introducing a configurable indication mechanism that alters the monitoring behavior from static (always monitor all occasions) to conditional (monitor based on indication). The network can signal whether user equipment should monitor delegated paging occasions, effectively changing the monitoring parameter state to optimize energy consumption while preserving communication reliability.

Inventive Principle:

Principle #35Parameter changes

2Use of energy by stationary object

If paging occasions are suspended for energy saving, then energy consumption decreases, but communication reliability may be compromised

Engineering Contradiction:

Improvenetwork energy consumptionVSAvoidpaging communication reliability

Core Design Contradiction:

Use of energy by stationary objectVSReliability

Solution Approach 1:

The patent introduces a paging delegation indication as an intermediary mechanism that mediates between energy saving goals and communication reliability. The network sends this indication to user equipment to inform them whether to monitor delegated paging occasions, ensuring that even when paging occasions are suspended or consolidated, reliable communication is maintained through proper notification and delegation mechanisms.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent implements feedback through paging delegation indications that provide information to user equipment about the status of paging occasions. This feedback mechanism allows the network to inform user equipment when paging is suspended or delegated, enabling devices to adjust their monitoring behavior accordingly while maintaining reliability through network-guided decisions.

Inventive Principle:

Principle #23Feedback

3Use of energy by moving object

If paging is delegated to different user equipment groups, then energy efficiency improves, but system complexity increases

Engineering Contradiction:

Improveuser equipment energy consumptionVSAvoidpaging system complexity

Core Design Contradiction:

Use of energy by moving objectVSDevice complexity

Solution Approach 1:

The patent applies universality by making paging occasions serve multiple functions and multiple user equipment groups. Paging occasions are not dedicated to single groups but can be shared and delegated across different groups dynamically. This multi-functionality reduces the total number of paging occasions needed, lowering energy consumption while the complexity is managed through standardized indication mechanisms.

Inventive Principle:

Principle #6Universality (Multi-functionality)

AI summary

A radio network node, which may be a terrestrial node or a non-terrestrial node, may determine to implement network energy saving measures based on a determined energy parameter value being determined to violate a corresponding energy parameter criterion. The node may transmit to a user equipment a paging delegation indication indicative that, during a paging occasion delegation period, at least one lightly loaded source paging occasion associated with the user equipment is to be temporarily suspended and delegated to a target paging occasion that may not be associated with the user equipment. The node may sleep during a delegated source paging occasion and may broadcast a paging message directed to the user equipment via the target paging occasion. The user equipment may avoid waking up during the delegated source paging occasion and instead may monitor the target paging occasion for paging messages during the paging occasion delegation period.
