Multipoint Communication Switching to Point-to-Point via P2P Pre-sharing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing multipoint communication systems face disconnections and increased resource consumption when switching from multipoint to point-to-point communication, leading to potential communication quality degradation and user interruption.
Innovation Solution
A method is introduced where devices share peer-to-peer (P2P) connection information during multipoint communication, allowing seamless switching to point-to-point communication when the number of participants decreases to two, thereby minimizing resource usage and user disruption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a device performs multipoint communication through a server relay scheme, then multipoint communication among three or more participants can be achieved, but disconnection occurs when switching to point-to-point communication and resource consumption increases
Solution Approach 1:
The patent applies preliminary action by having each participant device obtain and store P2P connection information of other participants in advance during multipoint communication. When the number of participants decreases to two, the devices can immediately switch to P2P communication using the pre-obtained connection information, avoiding disconnection and reducing server resource consumption without requiring re-negotiation of connection parameters
2Productivity
If P2P connection information is obtained in advance during multipoint communication, then switching to point-to-point communication becomes rapid and efficient, but device complexity increases
Solution Approach 1:
The patent uses the server as an intermediary to manage P2P connection information. The server facilitates the exchange and storage of connection information among participants during multipoint communication, and coordinates the switching process when participant count decreases. This intermediary approach simplifies individual device complexity while enabling rapid switching through centralized management
3Ease of operation
If switching from multipoint to point-to-point communication is performed without pre-sharing P2P connection information, then device complexity remains low, but communication disconnection occurs and user experience deteriorates
Solution Approach 1:
The patent applies preliminary action by having each participant device obtain and store P2P connection information of other participants in advance during multipoint communication. When the number of participants decreases to two, the devices can immediately switch to P2P communication using the pre-obtained connection information, avoiding disconnection and reducing server resource consumption without requiring re-negotiation of connection parameters

AI summary
There is provided a method of switching from multipoint communication to point-to-point communication while a device performs the multipoint communication with a plurality of participant devices. The method comprises: sharing, by the device, peer-to-peer (P2P) connection information of the device and P2P connection information of each of the plurality of participant devices, with the plurality of participant devices; and switching by the device, from the multipoint communication to the point-to-point communication using the P2P connection information of remaining participant devices of the plurality of participant devices in the multipoint communication when a total number of the remaining participant devices of the multipoint communication decreases to two.
