Solution Overview

Problem

Current communication management systems face challenges in handling crossed communication situations, particularly due to the assumption that called parties support double calls, leading to ergonomic and intuitive interface issues, resulting in dropped calls and inefficient voicemail management.

Innovation Solution

A method using a unique communication identifier for all communication creation requests between users, allowing detection of cross-communication situations without affecting network performance, and enabling seamless management of ongoing communications by closing existing sessions to handle incoming calls.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the system assumes called parties support double calls to enable incoming call notifications, then call management flexibility improves, but interface complexity increases and user error risk increases

Engineering Contradiction:
Improvecall management flexibilityVSAvoidinterface complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent introduces a message management system as an intermediary that handles crossed call situations. When a user is recording a voicemail and receives an incoming call, the system automatically manages the interaction through predefined message templates and automated responses, rather than requiring the user to directly manage the complex double-call interface. This mediator approach resolves the contradiction by maintaining call management flexibility while shielding users from interface complexity.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The system implements self-service mechanisms where the communication device automatically detects crossed call situations and executes appropriate actions without user intervention. The device autonomously identifies when it is recording a message and receives an incoming call, then automatically applies the correct handling logic (such as terminating the message recording or providing automated notification), eliminating the need for users to navigate complex interfaces during these situations.

Inventive Principle:
Principle #25Self-service

2Ease of operation

If the system provides detailed notification options for crossed calls, then user control improves, but the risk of unintentional call termination increases

Engineering Contradiction:
Improveuser controlVSAvoidcall termination accuracy
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The patent applies preliminary action by pre-configuring handling rules and message templates for crossed call situations before they occur. The system establishes predefined behaviors (such as automatic message termination or automated notification playback) that are triggered based on the detected situation, rather than requiring users to make decisions in the moment. This approach improves reliability by ensuring consistent, error-free execution while maintaining user control through the ability to pre-configure preferences.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system implements feedback mechanisms that provide users with clear information about the current communication state and the actions being taken. When a crossed call situation is detected, the system notifies the user of the situation and the intended action, allowing the user to confirm or modify the behavior. This feedback loop ensures that user control is maintained while preventing unintentional terminations through informed decision-making.

Inventive Principle:
Principle #23Feedback

3Measurement precision

If the system stores communication data to detect crossed calls, then detection accuracy improves, but network performance deteriorates

Engineering Contradiction:
Improvecrossed call detection accuracyVSAvoidnetwork performance
Core Design Contradiction:
Measurement precisionVSProductivity

Solution Approach 1:

The patent extracts only the essential information needed for crossed call detection from the communication data stream, rather than storing and processing complete communication records. The system identifies key parameters (such as caller ID, called party ID, and call timing) that are sufficient to detect crossed call situations, and uses only these extracted elements for detection logic. This approach maintains detection accuracy while minimizing network resource consumption.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The system applies partial action by implementing crossed call detection only for specific communication patterns that are most likely to result in crossed calls (such as voicemail recording scenarios). Rather than universally analyzing all communication data, the system focuses computational resources on high-probability situations, achieving sufficient detection accuracy while preserving overall network performance for other communication functions.

Inventive Principle:
Principle #16Partial or excessive action

AI summary

The invention relates to a communication management method, a communication management device, a communication method, and a communication device. In particular, the invention relates to communication management in a cross-communication situation. One object of the invention is a communication management method between communication devices comprising a request G1 to create a communication having a unique communication identifier id_A↔B identical id_A↔B for all requests to create a communication between at least one first user A and a second user B capable of allowing the establishment G2 of a communication identified by the unique communication identifier id_A↔B, between at least one communication device associated with the first user A and one communication device associated with the second user B.Thus, the invention makes it possible to detect ongoing communication using the same unique communication identifier id_A↔B, i.e. ongoing communications relating a first user A and a second user B regardless of the user originating the communication: detecting a situation of cross-communications between two users.
