Video Call Switching Between CS, ViLTE and OTT
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional video call technologies, such as OTT, CS, and ViLTE, often conflict and result in poor user experiences due to ineffective connection and lack of seamless switching between different communication types.
Innovation Solution
A video call switching method that detects the current terminal's video call state, prompts the user for switching when a different communication type is requested, and switches the current video call to the new type, maintaining communication connections and data transmission while updating call statuses, allowing users to freely select and switch between CS/ViLTE and OTT video calls.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple video call types (CS/ViLTE and OTT) are supported simultaneously, then adaptability and versatility are improved, but device complexity and conflict management become worse
Solution Approach 1:
The patent segments the video call handling into distinct communication types (CS/ViLTE and OTT) with separate detection and switching mechanisms. The terminal device independently manages each call type through specific protocols while providing unified user interaction, thereby reducing the complexity of managing multiple call types simultaneously.
Solution Approach 2:
The terminal device is designed with multi-functionality to handle both CS/ViLTE and OTT video calls through a universal switching mechanism. The call switching module can adaptively select and transition between different communication types, making the device capable of supporting multiple video call standards without requiring separate dedicated systems for each type.
2Ease of operation
If seamless switching between different communication types is enabled, then user experience is improved, but call connection stability may deteriorate
Solution Approach 1:
The patent implements preliminary detection of the current video call state and communication type before initiating switching. The terminal device proactively identifies the active call type (CS/ViLTE or OTT) and prepares appropriate switching actions in advance, ensuring that transitions occur smoothly without interrupting the ongoing call connection, thus maintaining both ease of operation and connection stability.
Solution Approach 2:
The switching mechanism incorporates feedback by continuously monitoring the current video call state and adjusting switching operations accordingly. The system detects whether a video call is currently active, identifies the communication type, and uses this information to control the switching process, ensuring that transitions only occur when appropriate and maintaining connection stability throughout the operation.
3Productivity
If call switching is implemented without user prompt, then productivity is improved, but loss of information increases due to unexpected call type changes
Solution Approach 1:
The patent implements feedback by providing prompt information to the user during the call switching process. When the terminal device detects a video call state and determines that switching between communication types is necessary, it generates and displays prompt information to notify the user of the current call type and the impending switching action, ensuring user awareness while maintaining efficient switching operations.

AI summary
Disclosed are a video call switching method, a storage medium and a terminal. The method comprises: upon receiving a video call request initiated by a caller terminal and in a video call state, acquiring a first communication type of the current video call and a second communication type of a video call initiated by the caller terminal; if the first communication type is different from the second communication type, giving a prompt of the video call request initiated by the caller terminal; and when a response operation for the video call request is received, switching the current video call to the video call of the second communication type.
