Solution Overview

Problem

In mobile communication services, when a terminal is in a call, it cannot answer third-party calls, leading to poor user experience as the network directly denies access without user intervention, and existing solutions require manual management, resulting in invalid access attempts and poor user experience for denied callers.

Innovation Solution

A method where the called terminal determines the priority of incoming third-party calls by comparing them with the priority of the current call, allowing or denying access based on this comparison, and sends a processing suggestion to the network device to manage third-party calls effectively, thereby improving user experience and reducing invalid access.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If the network directly denies third-party call access when the called terminal is busy, then the network can quickly manage call access, but the user experience deteriorates as users cannot make selection decisions

Engineering Contradiction:
Improvecall access management efficiencyVSAvoiduser decision-making capability
Core Design Contradiction:
ProductivityVSEase of operation

Solution Approach 1:

The terminal pre-judges the priority of incoming third-party calls before the call is fully established. The terminal determines whether to allow or deny access based on priority comparison in advance, rather than waiting for user manual decision or network direct denial. This preliminary action resolves the contradiction by enabling automated smart decision-making that maintains both efficiency and user intent.

Inventive Principle:
Principle #10Preliminary action

2Ease of operation

If call waiting service is activated to allow manual selection, then user decision rights are restored, but invalid access attempts increase and user experience for denied callers deteriorates

Engineering Contradiction:
Improveuser decision rightsVSAvoidinvalid access attempts
Core Design Contradiction:
Ease of operationVSLoss of time

Solution Approach 1:

The terminal performs priority judgment and access decision before the third-party call is fully established. By determining in advance whether to allow or deny access based on priority comparison, the system avoids multiple invalid access attempts and reduces time loss, while still maintaining user decision rights through the priority-based automated judgment.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The terminal autonomously manages third-party call access by automatically comparing priorities and making access decisions without requiring continuous user intervention. The terminal serves itself by intelligently judging whether to allow or deny incoming calls based on stored priority information, reducing both invalid access attempts and manual operation burden.

Inventive Principle:
Principle #25Self-service

3Productivity

If the network determines call access status, then call management is centralized and efficient, but the called terminal loses autonomy in making call selection decisions

Engineering Contradiction:
Improvecall management efficiencyVSAvoidterminal autonomy
Core Design Contradiction:
ProductivityVSAdaptability or versatility

Solution Approach 1:

The terminal autonomously performs priority judgment and access decision-making before the call is fully established. By determining in advance whether to allow or deny third-party call access based on priority comparison, the terminal maintains autonomy while achieving efficient call management, resolving the contradiction between centralized network control and terminal autonomy.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The terminal independently manages its own call access decisions by comparing the priority of incoming third-party calls with ongoing calls. The terminal serves itself by autonomously determining whether to allow or deny access based on stored priority information, maintaining terminal autonomy while achieving efficient call management without requiring network intervention.

Inventive Principle:
Principle #25Self-service

AI summary

The present invention discloses a method for a network device to process a third-party call, which is applied in a scenario where a third party originates a call when a called terminal is in a call process. The network device extracts a calling phone number of the third party, and notifies the calling phone number of the third party to the called terminal, where the called terminal has activated a call waiting service; and the network device receives a processing suggestion on the third-party call returned by the called terminal, and processes the third-party call according to the processing suggestion on the third-party call. A network device, a called terminal, and a method for a called terminal to process a third-party call are also disclosed. The processing suggestion on the third-party call is determined by comparing a priority of the calling phone number of the third party and a priority of the peer number, so that the third-party call is managed, thereby improving the user experience while avoiding invalid access.
