Priority Communication Network Switching Notification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems misinterpret a device's switch to a better network during emergency calls as a sudden disconnection, leading to unnecessary error processing.
Innovation Solution
A wireless communication system with a priority communication detection unit that switches the device to a second network with better quality and notifies the first network of the switch, preventing misinterpretation of the disconnection as an error.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the communicator switches to another wireless communication network with better communication quality during priority communication, then the communication quality is improved, but the currently connected network misrecognizes the event as a sudden disconnection error
Solution Approach 1:
The notification unit sends a notification message to the first wireless communication network before or during the network switching process, informing it that the communicator is transitioning to another network for priority communication. This preliminary action prevents the first network from misrecognizing the switching as a sudden disconnection error, thereby resolving the technical contradiction by preserving information about the intentional network transition.
2Reliability
If the communicator switches to another wireless communication network during priority communication, then the communication quality is improved, but unnecessary exception processing is triggered
Solution Approach 1:
By notifying the first wireless communication network in advance about the upcoming network switch for priority communication, the system prevents the first network from triggering unnecessary exception processing. The notification acts as a preemptive measure that informs the network of the intentional disconnection, thereby avoiding complex error handling procedures and reducing system complexity.
3Stability of the object's composition
If the communicator remains connected to the current wireless communication network during priority communication, then network stability is maintained, but communication quality deteriorates
Solution Approach 1:
The notification unit provides feedback to the first wireless communication network about the communicator's intention to switch networks for priority communication. This feedback mechanism allows the first network to understand that the disconnection is intentional and quality-driven, not a stability issue, thereby resolving the contradiction between maintaining connection stability and improving communication quality.

AI summary
A wireless communication system includes: a priority communication detection unit that detects priority communication from a communicator communicating wirelessly; a connection unit for connecting the communicator for which the priority communication is detected to a second wireless communication network that is different from a first wireless communication network to which the communicator is connected; a notification unit that notifies the first wireless communication network that the connection of the communicator to the second wireless communication network is due to the detected priority communication; and a disconnection unit that disconnects the communicator from the first wireless communication network after the notification unit notifies the first wireless communication network.
