Videoconferencing Connection Setup via Instant Messaging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face difficulties in establishing videoconferencing connections due to dynamic IP addresses, as they often lack access to directory servers, necessitating manual retrieval and entry of IP addresses for videoconference calls.
Innovation Solution
A videoconferencing system utilizing instant messaging (IM) servers to exchange connection information between videoconferencing units, where IM client applications automatically generate and send request messages for connection details like IP addresses, SIP addresses, and encryption settings, allowing for seamless videoconference setup.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual retrieval and entry of IP addresses is used to establish videoconferencing connections, then connection establishment is possible, but the process becomes time-consuming and operationally complex
Solution Approach 1:
The patent introduces an instant messaging server as an intermediary system that automatically exchanges connection information between videoconferencing units. Instead of manually retrieving and entering IP addresses, the IM server mediates the connection process by automatically obtaining connection details from the target unit and providing them to the initiating unit, thereby eliminating manual operations and time delays
Solution Approach 2:
The videoconferencing units automatically generate and exchange their own connection information through the IM server without requiring manual intervention. The system performs self-service by automatically obtaining, storing, and using connection details (IP addresses, port numbers, encryption settings) to establish connections, freeing users from manual configuration tasks
2Loss of information
If directory servers are used to obtain current IP addresses, then connection information can be retrieved, but the system requires additional infrastructure and increases device complexity
Solution Approach 1:
The instant messaging server performs multiple functions: it serves as a communication platform for users and simultaneously acts as a connection information exchange system for videoconferencing. By reusing the IM server infrastructure for dual purposes, the patent eliminates the need for separate directory servers while maintaining full functionality for obtaining connection information
Solution Approach 2:
The patent combines the connection information retrieval function with the existing instant messaging infrastructure. Instead of maintaining a separate directory server system, the connection information exchange is merged into the IM server's existing operations, reducing overall system complexity and infrastructure requirements

AI summary
A videoconferencing system includes a first videoconferencing unit coupled to a network and associated with a first instant messaging identity. The first videoconferencing unit obtains a second instant messaging identity and automatically sends a request instant message requesting videoconferencing connection information to the second instant messaging identity. A second videoconferencing unit is coupled to the network and is associated with the second instant messaging identity. The second videoconferencing unit receives the request instant message and automatically returns a response instant message including videoconferencing connection information to the first instant messaging identity. The first videoconferencing unit receives the response instant message and automatically obtains the videoconferencing connection information from the response instant message. Using the videoconferencing connection information, the first videoconferencing unit initiates a videoconference call with the second videoconference unit.
