Communication System Server Segmentation Emergency Reliability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication systems that rely on a single server device for sending and receiving communication data among terminal devices are prone to communication failures during emergencies, such as natural disasters or crimes, where data transmissions become concentrated, leading to system unavailability.
Innovation Solution
A communication system comprising a first server device that accepts and transmits communication data between terminal devices and a second server device that accepts communication data from one terminal device but only allows it to be viewed by another terminal device, with the ability to switch between sending communication data to either server device.

Engineering Contradiction Analysis
1Reliability
If communication data is transmitted through a single server device, then the system structure is simple and easy to manage, but communication failures occur during emergencies due to concentrated transmissions
Solution Approach 1:
The communication system is segmented into multiple server devices (first server device and second server device) with different functional characteristics. The first server device handles bidirectional communication while the second server device handles unidirectional communication from first terminal devices. This segmentation distributes communication load and provides redundancy, preventing communication failures during emergencies while maintaining manageable system complexity through clear functional division.
2Reliability
If multiple server devices are deployed to prevent communication failures, then communication reliability improves, but system complexity increases
Solution Approach 1:
Each server device is assigned specific local qualities or functional characteristics: the first server device is configured to accept and transmit communication data bidirectionally, while the second server device is configured to accept communication data only from first terminal devices and make it viewable by second terminal devices. This local quality differentiation allows multiple servers to work together for improved reliability while maintaining simple, well-defined individual server functions that ease system management.

AI summary
A communication system includes: a message management server device that accepts communication data sent from a school terminal device, transmits the communication data to a guardian terminal device, and accepts communication data sent from a guardian terminal device, and a bulletin board management server device that accepts communication data sent from the school terminal device, enables the guardian terminal device to view the communication data, but does not accept communication data from the guardian terminal device. It is possible to switch between sending communication data from the school terminal device to the message management server device and from the school terminal device to the message board management server device.
