VoIP Calling Group In-Progress Call Access Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Voice Over Internet Protocol (VoIP) communication systems lack the ability to allow access to in-progress calls within calling groups, limiting users' ability to join or manage ongoing calls across multiple VoIP phone lines.
Innovation Solution
The system enables a VoIP phone line to connect to an in-progress call within a calling group, providing status information and allowing requests to join or disconnect from the call based on privilege and security information, while also allowing the VoIP phone line to disconnect from the call without terminating the ongoing communication between other group members.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a VoIP phone line is allowed to connect to an in-progress call within a calling group, then user interaction and call management capability are improved, but system complexity and access control requirements increase
Solution Approach 1:
The system segments call access rights by creating distinct privilege levels (e.g., monitor mode vs. full participation) and applying them to different phone lines within a calling group. This allows granular control over which lines can join in-progress calls and under what conditions, resolving the complexity issue by organizing access control into manageable segments rather than treating all lines uniformly.
Solution Approach 2:
The system performs preliminary actions by pre-configuring privilege information and security settings for each VoIP phone line before calls occur. Access control policies, including which lines can join in-progress calls and what modes they can operate in, are established in advance. This eliminates the need for complex real-time decision-making during calls, reducing system complexity while maintaining versatility.
2Reliability
If privilege-based access control is implemented for joining in-progress calls, then call privacy and security are improved, but ease of operation deteriorates
Solution Approach 1:
The system implements self-service by automatically evaluating privilege information and security settings when a VoIP phone line attempts to join an in-progress call. The access control mechanism operates autonomously, checking pre-configured privileges and making authorization decisions without requiring manual intervention from call participants or administrators. This maintains call privacy through automated enforcement while preserving ease of operation for users.
3Reliability
If monitoring mode is allowed for joining calls without audio output, then call privacy is improved, but functionality is limited
Solution Approach 1:
The system applies dynamics by allowing VoIP phone lines to transition between different operational modes (monitor mode and full participation mode) based on their privilege information and the specific call context. A line can start in monitor mode for privacy purposes and potentially transition to full participation if privileges are granted, or different lines can have different modes simultaneously. This dynamic adaptability resolves the contradiction by making functionality context-dependent rather than fixed.

AI summary
A method of providing Voice-Over Internet Protocol (VoIP) communications can be provided by allowing a VoIP phone line included in a calling group of a plurality of VoIP phone lines to connect to an in-progress call between VoIP phone lines included in the calling group.
