Voice Call Video Link Switching for Emergency Group Communication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current telecommunications systems lack the capability to seamlessly integrate video representation and group call functionality into traditional voice calls, particularly in emergency situations or when additional assistance is needed.
Innovation Solution
The implementation of processing circuitry in user equipment (UE) and servers that allows for the automatic switching from a voice call to a VoIP-based video session, enabling video support and automatic addition of third parties to calls, using video call links and signaling from servers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional voice call systems are used, then call simplicity and compatibility are maintained, but video representation and group call functionality are unavailable
Solution Approach 1:
The patent merges voice call and video call functionalities into a unified communication system. The processing circuitry integrates both voice and video call capabilities, allowing seamless switching and combination of these functions within a single call interface, thereby providing video representation without requiring separate systems.
Solution Approach 2:
The communication system is designed with multi-functionality to handle both traditional voice calls and enhanced video calls through the same processing circuitry. The system can adaptively switch between voice-only mode and video-enabled mode based on network conditions and user needs, making the system versatile across different call types.
2Adaptability or versatility
If video call functionality is added to voice calls, then communication capability is enhanced, but system complexity and resource consumption increase
Solution Approach 1:
The patent segments the call management into distinct functional modules: voice call handling, video call link generation, and group call coordination. Each module operates independently but can be activated together, allowing group call functionality to be added without completely redesigning the existing voice call system.
Solution Approach 2:
The processing circuitry acts as an intermediary that coordinates between voice call participants and video call participants. It manages the switching between voice and video modes and handles the addition of third parties to calls, simplifying the overall system architecture by centralizing control logic.
3Speed
If automatic switching from voice to video is implemented, then response time in emergencies is reduced, but control precision and user consent management become more difficult
Solution Approach 1:
The system performs preliminary actions by pre-configuring automatic switching rules and obtaining user consent preferences in advance. When a voice call is initiated, the system checks pre-set conditions (such as emergency detection or user-defined triggers) and automatically switches to video mode if conditions are met, reducing response time while maintaining user control through pre-established preferences.

AI summary
An apparatus configured to initiate a voice call to a target device, generate, for transmission to a first server, a request for a video call link upon a determination that a trigger event has occurred, process, based on signaling received from the first server, a video call link, generate, for transmission to a base station, a message comprising the video call link to be forwarded to the target device and establish a video session with the target device using the video call link while still maintaining the voice call with the target device.
