Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

In communication technologies, when network deployment changes, user equipment (UE) remaining in a power-saving measurement mode cannot efficiently utilize network resources, as the stricter measurement trigger conditions prevent timely switching to neighboring cells or frequency points, leading to suboptimal network resource allocation.

Innovation Solution

A method is introduced where network equipment sends configuration information to UE to switch from a first measurement mode to a second mode with easier trigger conditions, allowing UE to measure neighboring cells or frequency points, enabling better resource utilization during network changes such as new cell planning or frequency spectrum re-planning.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Use of energy by moving object

If UE adopts power-saving trigger measurement mode with stricter measurement trigger conditions, then power consumption is reduced, but network resource utilization deteriorates when network deployment changes

Engineering Contradiction:

Improvepower consumptionVSAvoidnetwork resource utilization

Core Design Contradiction:

Use of energy by moving objectVSAdaptability or versatility

Solution Approach 1:

The patent implements dynamic switching between two measurement modes: a power-saving mode with stricter trigger conditions and a normal mode with easier trigger conditions. The network equipment sends configuration information to UE to switch modes based on network deployment changes, allowing the system to adapt measurement behavior dynamically rather than using a fixed measurement policy

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The patent changes the measurement trigger condition parameters by switching between two sets of conditions. The first measurement trigger condition has stricter thresholds for triggering measurements of neighboring cells and frequency points, while the second measurement trigger condition has more lenient thresholds. This parameter switching enables the system to balance power saving and network resource utilization based on operational context

Inventive Principle:

Principle #35Parameter changes

2Use of energy by moving object

If UE continues to maintain power-saving trigger measurement mode after network status changes, then power consumption remains low, but network cannot page UE effectively and network resources cannot be used rationally

Engineering Contradiction:

Improvepower consumptionVSAvoidnetwork paging reliability

Core Design Contradiction:

Use of energy by moving objectVSReliability

Solution Approach 1:

The system dynamically adjusts measurement behavior by switching between measurement modes based on network status changes. When network deployment changes occur (such as new cell planning or frequency spectrum re-planning), the network equipment sends configuration information to switch UE from power-saving mode to normal mode, ensuring reliable network paging and resource utilization while maintaining power efficiency during stable periods

Inventive Principle:

Principle #15Dynamics

3Use of energy by moving object

If UE uses stricter measurement trigger conditions, then measurement frequency is reduced saving power, but UE cannot timely switch to neighboring cells or frequency points during network changes

Engineering Contradiction:

Improvepower consumptionVSAvoidcell reselection speed

Core Design Contradiction:

Use of energy by moving objectVSSpeed

Solution Approach 1:

The patent implements dynamic measurement mode switching that adjusts measurement trigger conditions based on network deployment status. During network changes, the system switches to normal measurement mode with easier trigger conditions, enabling faster cell reselection to newly planned cells or frequency points. During stable periods, it maintains power-saving mode with stricter conditions to reduce power consumption

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The network equipment proactively sends configuration information to UE to switch measurement modes before network changes affect service quality. This preliminary action ensures that UE is ready to perform measurements and switch to neighboring cells or frequency points timely when network deployment changes occur, preventing service degradation

AI summary

A method of switching a measurement mode and a device thereof are provided. The method includes: sending, by a network equipment, configuration information to a user equipment, to enable the user equipment to switch from a first measurement mode to a second measurement mode according to the configuration information; where the first measurement mode is a mode of triggering the user equipment to measure a current cell and/or a neighboring cell in the case that a first measurement trigger condition is met; and the second measurement mode is a mode of triggering the user equipment to measure a current cell and/or a neighboring cell in the case that a second measurement trigger condition is met.
