Solution Overview

Problem

Mobile terminals lack an efficient method to automatically respond to incoming calls, especially when the user is unable to respond, and fail to distinguish between users and strangers, limiting personalized responses.

Innovation Solution

A mobile terminal with an automatic response function, utilizing a voice agent that performs authentication and selects a response mode based on the caller's identity, providing different response ranges for users, acquaintances, and strangers through voice or UI interfaces.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If automatic response function is implemented, then user convenience is improved when unable to respond to calls, but device complexity increases due to authentication and voice agent systems

Engineering Contradiction:
Improveease of operationVSAvoiddevice complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The system performs preliminary authentication of the caller's identity before generating a response. The controller authenticates whether the caller is a user or stranger in advance, and based on this preliminary authentication result, selects appropriate response modes (voice response, UI response, or no response). This preliminary action reduces the need for complex real-time decision-making during the call response process.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

A voice agent is introduced as an intermediary between the automatic response system and the user. The voice agent receives voice inputs from callers, transmits them to the controller for processing, and delivers the controller's responses back to callers. This intermediary layer simplifies the overall system architecture by centralizing the interaction logic and reducing the complexity of direct system-caller communication.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Measurement precision

If authentication procedure is added to distinguish users from strangers, then response accuracy is improved, but loss of time increases due to additional authentication steps

Engineering Contradiction:
Improveresponse accuracyVSAvoidloss of time
Core Design Contradiction:
Measurement precisionVSLoss of time

Solution Approach 1:

The system implements a simplified authentication procedure that performs only the necessary authentication to distinguish between users and strangers, rather than implementing comprehensive identity verification. The controller determines whether the caller is a user or stranger based on basic authentication information, which is sufficient for selecting the appropriate response mode. This partial authentication approach achieves the required response accuracy while minimizing time loss.

Inventive Principle:
Principle #16Partial or excessive action

3Adaptability or versatility

If multiple response modes are provided for different callers, then adaptability is improved, but device complexity increases due to mode selection logic

Engineering Contradiction:
ImproveadaptabilityVSAvoiddevice complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The system dynamically adjusts the response mode based on the authentication result. The controller automatically selects from multiple response modes (voice response, UI response, or no response) according to whether the caller is authenticated as a user or stranger. This dynamic adaptation allows the system to provide versatile responses for different scenarios while keeping the control logic centralized and manageable, avoiding the need for complex static configuration of multiple response paths.

Inventive Principle:
Principle #15Dynamics

AI summary

The present invention relates to a mobile terminal and, more specifically, to a mobile terminal and a method for controlling the same which are capable of automatically responding to a caller when a user cannot respond to a call or when a given condition is satisfied. The method for controlling a mobile terminal related to an embodiment of the present invention may comprise the steps of: activating an automatic response function when a preset activation condition is satisfied; accepting a voice call when a call signal is received form a caller; performing an authentication procedure determining an automatic response type: and performing a function requested by the caller through at least one, corresponding to the determined response type, among voice, text and a graphic user interface, within a range corresponding to the result of the authentication procedure, while the accepted voice call is connected.
