Solution Overview

Problem

Smartphones in standby mode consume excessive power due to continuous monitoring of wireless communication channels and data service synchronization, leading to reduced standby time and potential base station overload.

Innovation Solution

A power saving method that acquires and analyzes usage time for each function in a communication terminal, activating only during periods of frequent use, thereby reducing wake-up times and power consumption.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the smart phone continuously monitors wireless communication channels and maintains data service synchronization, then communication reliability is improved, but standby power consumption increases violently

Engineering Contradiction:
Improvecommunication reliabilityVSAvoidstandby power consumption
Core Design Contradiction:
ReliabilityVSUse of energy by moving object

Solution Approach 1:

The patent implements discontinuous reception (DRX) technology where the smartphone alternates between active monitoring periods and sleep periods. The terminal device wakes up at specific intervals to monitor paging channels and perform data service synchronization, then enters sleep state to conserve power. This periodic action pattern resolves the contradiction by maintaining communication reliability during active periods while reducing power consumption during sleep periods.

Inventive Principle:
Principle #19Periodic action

2Reliability

If the smart phone wakes up frequently for data service synchronization, then data service reliability is improved, but standby current increases and base station resources are wasted

Engineering Contradiction:
Improvedata service reliabilityVSAvoidstandby current
Core Design Contradiction:
ReliabilityVSLoss of energy

Solution Approach 1:

The patent applies periodic action by scheduling data service synchronization at specific intervals rather than continuously. The terminal wakes up at predetermined times to perform synchronization and then returns to sleep state, reducing standby current while maintaining data service reliability through regular periodic updates.

Inventive Principle:
Principle #19Periodic action

Solution Approach 2:

The patent implements partial action by performing data service synchronization only when necessary rather than continuously. The terminal selectively wakes up to perform synchronization tasks and remains in sleep state otherwise, reducing unnecessary power consumption while maintaining adequate data service reliability.

Inventive Principle:
Principle #16Partial or excessive action

3Adaptability or versatility

If the smart phone activates all functions anytime and anywhere, then service availability is improved, but power consumption increases

Engineering Contradiction:
Improveservice availabilityVSAvoidpower consumption
Core Design Contradiction:
Adaptability or versatilityVSUse of energy by moving object

Solution Approach 1:

The patent applies dynamics by making the smartphone's functional state adaptable rather than static. The terminal dynamically switches between active and sleep states based on service requirements, user needs, and network conditions. This dynamic adaptation allows the phone to maintain service availability when needed while conserving power during periods of low activity.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent uses periodic action to activate functions at scheduled intervals rather than continuously. The terminal wakes up periodically to perform necessary functions such as monitoring paging channels and data service synchronization, then enters sleep state, resolving the contradiction between service availability and power consumption.

Inventive Principle:
Principle #19Periodic action

AI summary

Embodiments of the present invention relates to the field of wireless communication, and provide a power saving method, apparatus and communication terminal, to reduce power consumption of a communication terminal and prolong standby time by reducing the number of wakeup times of the communication terminal in a standby state. The method includes: acquiring use time of each function of a communication terminal in one sampling cycle; executing a statistical algorithm on the use time of each function of the communication terminal to separately obtain a duration of frequent use of each function of the communication terminal in the sampling cycle; and correspondingly activating each function of the communication terminal in the duration of frequent use of each function. Embodiments of the present invention are used for power saving of the communication terminal.
