Communication Terminal Shutdown Notification Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Communication systems lack the ability to notify users or other devices when a communication terminal is shutting down due to low power or user-initiated shutdown, leading to unclear reasons for failed connections or session drops.
Innovation Solution
A communication system where a first communication terminal detects low power or user-initiated shutdown and sends a notification message to connected devices, including information about the power level, geographical location, and optional images or audio, to inform users and potentially redirect communication requests to another terminal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If a communication terminal shuts down without notification, then the device can be turned off to save power or respond to user input, but the other party cannot determine why the connection failed
Solution Approach 1:
The system performs preliminary action by sending a shutdown notification message before the communication terminal actually shuts down. The message is transmitted in advance to inform the other party of the upcoming shutdown and its reason, allowing the other party to take appropriate actions such as redirecting calls or saving important information before the connection is lost.
2Ease of operation
If a session is dropped without notification, then the terminal can respond to power loss or user input, but there is no way to communicate why the session failure occurred
Solution Approach 1:
The system implements feedback by providing the other party with information about why the session is being dropped. The shutdown notification message includes reasons such as low battery level or user-initiated shutdown, giving the receiving party feedback about the session failure cause and enabling better session management decisions.
3Loss of information
If the terminal sends detailed notification messages including power level and location information, then the other party gains comprehensive information about the shutdown, but the message size and processing requirements increase
Solution Approach 1:
The notification message is segmented into distinct information elements including power level indicators, geographical location data, and shutdown reason codes. This segmentation allows the receiving device to process only the relevant portions of the message based on its specific needs, reducing overall processing complexity while maintaining information completeness.

AI summary
A method and apparatus for transmitting a notification of a shutdown event includes a communication terminal turning off or otherwise shutting down and prior to turning off sending a notification to a third party device such as an access point, base station, server, or proxy, that identifies information relating to the shutting down of the terminal such as a location, purpose for the shutdown and other relevant information. Subsequent devices that attempt to establish a communication connection with the terminal may then receive the notification or information from the notification via the third party device. The sending of information relating to the notification or the notification by the third party can also trigger another action. One example of such an action is the forwarding of the communication connection request to another device to receive that request based upon a predefined rule or a predefined forwarding address.
