Terminal Device Emergency Signal Priority Notification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing emergency communication systems in wireless communication terminals may disrupt group communication when a terminal device transmits an emergency signal, leading to potential loss of contact with the original sender and inefficient response to emergency situations.
Innovation Solution
A terminal device that receives emergency signals from multiple sources sets priorities for these devices based on their group affiliation and distance, allowing for appropriate notification and response to emergency situations without disrupting group communication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If group reconstruction is performed to create a new group when another terminal device transmits an emergency message, then emergency communication capability is improved, but communication continuity with the original sender is lost
Solution Approach 1:
The patent segments the emergency communication process into distinct phases: original emergency message transmission, group reconstruction for new emergencies, and selective notification. By dividing the communication flow, the system can maintain the original group structure for continuity while creating temporary notification paths for new emergencies, thus preserving communication with the original sender while enabling emergency response.
Solution Approach 2:
The patent introduces a server as an intermediary that manages group reconstruction and message forwarding. The server coordinates between the original terminal device, the new emergency sender, and group members, enabling group reconstruction without completely breaking the original communication channel. The intermediary facilitates selective notification while maintaining original communication continuity.
2Reliability
If all emergency signals are notified equally, then comprehensive emergency coverage is improved, but notification efficiency deteriorates due to information overload
Solution Approach 1:
The patent applies local quality by differentiating notification priorities based on the relationship between the receiving terminal and the emergency sending terminal. Terminals in the same group receive high-priority notifications, while others receive low-priority or no notifications. This selective approach ensures comprehensive coverage for relevant users while filtering out noise for others, thereby improving notification efficiency without sacrificing essential emergency coverage.
Solution Approach 2:
The patent changes the notification parameter from uniform treatment to priority-based treatment. By introducing priority levels (high and low) based on group membership and terminal relationships, the system transforms the notification mechanism from equal coverage to differentiated coverage, improving efficiency by reducing unnecessary notifications while maintaining reliability for critical cases.
3Productivity
If priorities are set for multiple emergency signal sources, then notification efficiency is improved, but device complexity increases
Solution Approach 1:
The patent implements self-service by enabling terminal devices to automatically determine and set priorities based on pre-established group relationships and terminal identification information. The device compares its own group membership with the sending terminal's group membership and automatically assigns high or low priority without manual intervention. This automation reduces the perceived complexity for users while maintaining efficient priority-based notification.
Solution Approach 2:
The patent applies preliminary action by pre-establishing group relationships and terminal identification information before emergency situations occur. These pre-configured data structures enable rapid priority determination during emergencies without requiring complex real-time analysis. The preliminary setup of group memberships and identification protocols simplifies the priority management process during actual emergency notifications.

AI summary
In a terminal device, a receiver receives a plurality of signals from a plurality of other terminal devices. When the receiver has received a plurality of emergency signals, a setting unit sets priorities for a plurality of other terminal devices that are the transmission sources for the plurality of emergency signals. A notification unit gives notification of information regarding the plurality of other terminal devices that have transmitted the emergency signals, based on the priorities that have been set by the setting unit.
