Solution Overview

Problem

Current call management systems provide a poor user experience by maintaining a conference call interface even when only two participants are on a call, which is equivalent to a single line call, leading to an inappropriate and confusing user interface.

Innovation Solution

A call management method that continuously detects the call type and switches the interface to match the current call type, changing from a conference call interface to a single line call interface when the number of participants reduces to two, thereby optimizing the user interface and improving user experience.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the system maintains a conference call interface when only two participants are on the call, then the call state management remains simple and consistent with protocol standards, but the user experience deteriorates due to the inappropriate and confusing interface display

Engineering Contradiction:
Improvecall state management consistencyVSAvoiduser experience
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The patent applies local quality by differentiating the interface display from the underlying call state. The system maintains the conference call state in the protocol layer while applying a different visual representation (single line call interface) at the user interface layer. This resolves the contradiction by allowing the interface to have local quality that matches user expectations without compromising the reliability of the call state management.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The patent introduces an intermediary layer between the call state management and the user interface. This intermediary detects the number of participants and selectively applies different interface types (conference call interface or single line call interface) based on the participant count. This mediator resolves the contradiction by decoupling the protocol-level call state from the user-perceived interface type.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Device complexity

If the system uses a fixed conference call interface for all calls, then the implementation complexity remains low, but the adaptability to different call scenarios deteriorates

Engineering Contradiction:
Improveinterface implementation complexityVSAvoidinterface adaptability to call type
Core Design Contradiction:
Device complexityVSAdaptability or versatility

Solution Approach 1:

The patent applies dynamics by making the interface type changeable based on real-time detection of call conditions. The system dynamically switches between conference call interface and single line call interface according to the number of participants. This resolves the contradiction by introducing minimal dynamic behavior that adapts the interface to different call scenarios without requiring complex restructuring of the entire system.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent uses parameter changes by detecting the number of participants as a key parameter and using it to determine which interface type to display. When the participant count changes from 3 or more to 2, the system changes the interface parameter from conference call mode to single line call mode. This resolves the contradiction by using a simple parameter (participant count) to trigger interface adaptation.

Inventive Principle:
Principle #35Parameter changes

AI summary

The present disclosure relates to a call management method and apparatus. It relates to the field of wireless communication application and solves the problem of poor user experience when a conference call interface is used in a single line call. The method includes: detecting (201) a call type of a call; starting (202) a call management interface corresponding to a current call type, when the call type of the call is changed. The technical solution provided by the present disclosure is applicable to the management of the user interface of the conference call, and realizes flexible switching and changing of the interface when participants of the conference call change.
