RCS Video Sharing Threshold Control for Call Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
During video calls using RCS services, insignificant variance in screen images can lead to reduced data transmission, prompting network resource changes and potentially causing call drops.
Innovation Solution
The method involves determining if a video sharing operation is in progress and if the connected cell supports HSPA communication, then transmitting data only when the transmission amount meets a predetermined threshold, thereby preventing unnecessary resource changes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If data is transmitted in reduced size during video sharing with insignificant screen image variance, then data transmission efficiency is improved, but network may request resource change causing call drop
Solution Approach 1:
The patent changes the parameter of data transmission by introducing a threshold mechanism. When screen image variance exceeds the threshold, normal video sharing continues; when variance is below the threshold, data transmission is suspended or reduced. This parameter-based control resolves the contradiction by adapting transmission behavior to actual content changes, improving efficiency without compromising call stability.
Solution Approach 2:
The patent implements dynamic control of data transmission based on real-time screen image variance monitoring. The system continuously adjusts transmission behavior according to the current state of video content changes, transitioning between active transmission and suspended transmission modes. This dynamic approach allows the system to optimize efficiency while maintaining reliability by only reducing transmission when it is safe to do so.
2Adaptability or versatility
If network requests resource change during video sharing, then network resource allocation is optimized, but call drop occurs
Solution Approach 1:
The patent applies preliminary action by monitoring screen image variance and preparing transmission control decisions before network resource change requests occur. By detecting insignificant variance early and preemptively suspending or reducing data transmission, the system prevents the need for network resource changes that would cause call drops. This proactive approach maintains call stability while still allowing network optimization when appropriate.

AI summary
A method for controlling a video sharing through a rich communication suite (RCS) service of an electronic device may comprise the steps of: receiving a resource change request from a network; upon receiving the request, determining whether there is a video sharing operation through the RCS service; if there is a video sharing operation, determining whether a cell connected to the electronic device is a cell that supports a first communication method; if it is determined that the cell connected to the electronic device is a cell that supports the first communication method, determining whether an amount of change of data is greater than or equal to a specific amount of change; and if the amount of change of data is greater than or equal to the specific amount of change, forwarding the request to an application supporting the RCS service.
