Video Call Transfer with Multimedia Resource Function
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current video call transfer technologies lack flexibility, allowing only video call transfers and no option for the transfer target to accept or decline as an audio call, limiting user choice and functionality.
Innovation Solution
The system enables transferring an existing video call as either a video or audio call and allows the transfer target to choose between accepting as a video call, downgrading to an audio call, or declining, using a multimedia resource function to maintain the video connection during the transfer process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If video call transfer is implemented with existing technology, then call transfer functionality is provided, but flexibility is limited and user choice is restricted
Solution Approach 1:
The call transfer system dynamically adapts the call type (video or audio) based on real-time user selections. The transferor can choose to transfer as video or audio, and the transfer target can choose to accept as video, audio, or decline, making the system flexible and adaptive to different user needs during the transfer process
Solution Approach 2:
The call transfer system is designed to handle multiple call types (video and audio) and multiple user choices (accept as video, accept as audio, decline) within a single unified system. This multi-functional design allows one system to serve multiple purposes and user scenarios without requiring separate systems for each call type or transfer scenario
2Adaptability or versatility
If only video call transfer is allowed, then video quality is maintained, but user flexibility and choice are reduced
Solution Approach 1:
The system dynamically adjusts the call type during transfer based on user preferences. The transferor can select to transfer as video or audio, and the transfer target can select to accept as video or audio. This dynamic adaptation allows the system to maintain video quality when needed while providing flexibility when users prefer audio-only communication
Solution Approach 2:
The system changes the call parameters (video or audio mode) during the transfer process based on user selections. By allowing parameter changes in the call type, the system can adapt to different user needs while maintaining connection stability through proper parameter negotiation and session management
3Ease of operation
If transfer target has limited choices, then system complexity is reduced, but user experience and functionality are limited
Solution Approach 1:
The transfer interface dynamically presents different options based on the transfer scenario. The transferor sees options to transfer as video or audio, while the transfer target sees options to accept as video, accept as audio, or decline. This dynamic interface adapts to the specific needs of each user in the transfer process
Solution Approach 2:
The transfer process is segmented into distinct decision points: the transferor's decision on how to transfer (video or audio) and the transfer target's decision on how to accept (video, audio, or decline). This segmentation allows each user to make independent choices without overwhelming complexity, presenting options in a structured and manageable way

AI summary
Systems and methods for providing additional video call transfer functionality are disclosed. The systems and methods can enable a video call between a first user equipment (UE) and a second UE to be transferred to a video call between the second UE and a third UE either a video call or an audio call. The systems and methods can also enable the third UE to accept a transferred video call or to request that the video call be downgraded to an audio call. The systems and methods can incorporate a multimedia resource function (MRF) to connect to the second UE while the transfer is being negotiated and effected. The MRF can provide an audio stream and a video stream to the second UE to provide a “video hold” feature—to prevent the video call from dropping to an audio call automatically or dropping altogether.
