Solution Overview

Problem

Mobile terminals experience high power consumption during voice calls due to the continuous processing and transmission of both valid and invalid voice data, leading to reduced battery life and increased system load.

Innovation Solution

Implementing voiceprint modeling on the mobile terminal to differentiate between valid and invalid voice data by establishing and matching voiceprint models with stored models, allowing only valid data to undergo baseband and radio frequency processing and transmission.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If continuous voice data processing and transmission is performed during voice calls, then communication reliability is improved, but power consumption increases

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

Solution Approach 1:

The patent extracts and removes invalid voice data (environmental noises, echo, other people's voices) from the continuous voice stream before baseband and radio frequency processing. By taking out only the useful valid voice data and discarding invalid data, the system reduces processing load and power consumption while maintaining communication reliability through selective transmission of valid data only.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The patent applies different processing quality to different parts of the voice data. Valid voice data undergoes full processing and transmission, while invalid data (environmental noises, echo) is filtered out. This local differentiation of processing quality allows the system to maintain communication reliability for valid data while reducing power consumption by avoiding processing of invalid data.

Inventive Principle:
Principle #3Local quality

2Loss of information

If all voice data is processed and transmitted regardless of validity, then data completeness is improved, but system load increases

Engineering Contradiction:
Improvedata completenessVSAvoidsystem load
Core Design Contradiction:
Loss of informationVSProductivity

By taking out only the useful valid voice data and discarding invalid data, the system reduces processing load and power consumption while maintaining communication reliability through selective transmission of valid data only.

This local differentiation of processing quality allows the system to maintain communication reliability for valid data while reducing power consumption by avoiding processing of invalid data.

3Use of energy by moving object

If voiceprint modeling and validation is implemented, then power consumption is reduced, but device complexity increases

Engineering Contradiction:
Improvepower consumptionVSAvoiddevice complexity
Core Design Contradiction:
Use of energy by moving objectVSDevice complexity

Solution Approach 1:

The patent performs voiceprint modeling and validation as a preliminary action before the main baseband and radio frequency processing. By establishing voiceprint models in advance and validating voice data against these models beforehand, the system identifies valid and invalid data early, allowing subsequent processing to focus only on valid data, thus reducing overall power consumption.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent introduces voiceprint modeling and validation as an intermediary layer between the microphone and the baseband processing. This intermediary layer filters and validates voice data before it reaches the main processing chain, acting as a gatekeeper that prevents invalid data from consuming system resources, thereby reducing power consumption with acceptable complexity increase.

Inventive Principle:
Principle #24Intermediary (Mediator)

AI summary

A method for reducing call power consumption of a mobile terminal and mobile terminal are disclosed in the present invention, wherein, the method includes: in a voice call process, the mobile terminal performing voiceprint modeling on an audio signal collected by the mobile terminal itself to obtain a voiceprint model, and judging whether the obtained voiceprint model matches with a stored voiceprint model of the user; if not matching, giving up performing wireless transmission on the collected audio signal or giving up performing baseband and radio frequency processing and wireless transmission on the collected audio signal, and if matching, performing the baseband and radio frequency processing and wireless transmission on the audio signal. With the present invention, voice call power consumption of the mobile terminal is reduced, battery usage time of the mobile terminal is extended, and user experience is enhanced.
