Video Call File Transfer via Dedicated Link
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing video call service transactions require higher network bandwidth, leading to lower effectiveness and stability in acquiring user files due to insufficient bandwidth resources.
Innovation Solution
A method and system that includes a video call device and a file push server, where the video call device receives a service request, establishes a video call data transmission link, and determines a file transmission link based on the communication address and file type, using a file push server to upload and forward files across servers when necessary, ensuring independent file and video call data transmission links.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If file transmission is performed through video call data transmission link, then file transmission can be realized, but network bandwidth resources are insufficient leading to low effectiveness and stability
Solution Approach 1:
The patent segments the data transmission into two independent channels: video call data transmission link and file transmission link. The video call link handles video/audio data while the file transmission link handles file transfers. This segmentation allows each link to allocate bandwidth independently, preventing file transmission from competing with video call quality requirements, thereby improving file acquisition effectiveness and stability without sufficient video call bandwidth.
Solution Approach 2:
The patent introduces a file transmission server as an intermediary component. The server receives file transmission requests, manages file transfer processes, and coordinates between user terminals and account executive terminals. This intermediary handles the complexity of cross-server file transfers, optimizes bandwidth utilization, and ensures reliable file delivery independent of video call bandwidth constraints.
2Measurement precision
If video call resolution is increased to improve picture quality, then user experience is improved, but network bandwidth consumption increases further reducing file transmission effectiveness
Solution Approach 1:
By separating file transmission from video call data transmission into independent links, the patent eliminates the trade-off between video resolution and file transmission quality. High-resolution video calls can maintain picture quality without competing for bandwidth with file transfers, as files traverse a dedicated transmission link managed by the file transmission server.
3Adaptability or versatility
If user and account executive are located at different servers, then service flexibility is improved, but direct file transmission cannot be performed requiring video picture capture which reduces file quality
Solution Approach 1:
The file transmission server acts as a mediator that enables direct high-quality file transmission between users and account executives even when they are on different servers. The server handles cross-server routing and file transfer protocols, eliminating the need to fall back to low-quality video picture capture. This maintains both service flexibility (users can be on different servers) and file quality (direct file transmission is always available).

AI summary
The present disclosure provides a method for responding to video call service and system, including: receiving a video call service request by the video call device; calling a video call connection process to establish a video call data transmission link with the call peer based on a communication address; locally acquiring a target file as indicated by the file transmission request, and determining a link number of the file transmission link for transmitting the target file according to the communication address and a file type of the target file, if a file transmission request sent by the call peer is received; uploading the target file to a file push server through a file uplink if the link number is not included in a local link list; and transmitting the target file to the call peer through the file transmission link corresponding to the link number.
