Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current call centers face challenges in implementing video intercommunication due to network complexity and the need for additional devices like Video Intercommunication Gateways (VIG), which increase maintenance and operational costs, while existing solutions do not efficiently manage media stream switches between 3G networks and call centers.
Innovation Solution
A video media server with a code converting module and video access control system module that supports multiple coding formats, enabling media negotiation and stream switching between call centers and 3G networks, thereby eliminating the need for additional network elements and reducing operational costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a Video Intercommunication Gateway (VIG) device is added to realize intercommunication between call center and 3G network, then video intercommunication function is achieved, but network complexity and maintenance cost increase
Solution Approach 1:
The patent merges the VIG device functions into the existing video media server by adding a video access control system module. This integration eliminates the need for separate VIG devices, reducing network complexity while maintaining video intercommunication functionality between call centers and 3G networks
Solution Approach 2:
The video media server is enhanced with multi-functionality to handle both traditional video conferencing and video intercommunication with 3G networks. The video access control system module enables the server to negotiate with multiple network elements using different protocols, making it a universal platform for various video communication scenarios
2Adaptability or versatility
If a Video Intercommunication Gateway (VIG) device is added to enable video intercommunication, then compatibility between call center and 3G network is achieved, but operational cost increases
Solution Approach 1:
The patent combines the protocol conversion and media stream switching functions into the existing video media server infrastructure. By reusing existing hardware and software resources, the solution avoids the additional operational costs associated with maintaining separate VIG devices while achieving protocol compatibility between RTP-based call centers and 3G-324M networks
3Ease of operation
If media stream switch is requested after video call accesses call center, then call center operation requirements are met, but network element compatibility problems occur
Solution Approach 1:
The video access control system module acts as an intermediary between the call center and 3G network. It manages media stream switching by negotiating with both network elements, translating between RTP and 3G-324M protocols, and coordinating the switching process to ensure compatibility and smooth operation during call center procedures
