SUPL Triggered Location Session Termination Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional SUPL-based triggered location services face errors and resource wastage due to unintentional termination of triggered sessions, where the target terminal does not notice the session end, leading to repeated requests and unnecessary resource maintenance.
Innovation Solution
A method is introduced to send a dedicated or common end message to the target terminal when a condition set for the triggered session is satisfied, allowing the terminal and server to recognize the session end and delete related information, preventing errors and resource wastage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the triggered session is paused without proper termination notification, then the terminal can pause the session temporarily, but the terminal does not notice the session end and may send repeated requests causing resource wastage
Solution Approach 1:
The patent implements a feedback mechanism where the network side sends an end message to the terminal when the triggered session is terminated. This feedback loop ensures the terminal is properly notified of session termination, preventing repeated requests and resource wastage while maintaining the pause function's ease of operation.
Solution Approach 2:
The patent performs preliminary action by sending the end message before the session is fully terminated from the network side perspective. This ensures the terminal receives termination notification in advance, allowing it to properly clean up resources and avoid sending repeated requests.
2Productivity
If the triggered session continues running without termination, then location services remain active, but network resources are wasted when the session should have ended
Solution Approach 1:
The end message sent by the network side to the terminal provides feedback about session termination status. This enables the terminal to accurately track when the session should end and stop maintaining it, thereby reducing network resource consumption while ensuring location services remain available when needed.
Solution Approach 2:
The patent implements discarding and recovering by having the terminal delete session information after receiving the end message. This ensures network resources are released (discarded) when the session should end, while the session can be recovered (re-established) when location services are needed again, optimizing resource utilization.
3Adaptability or versatility
If the terminal sends repeated requests for triggered location service, then location information can be obtained, but error occurrence increases due to unintentional session termination
Solution Approach 1:
The end message provides critical feedback to the terminal about session termination status. This feedback mechanism enables the terminal to accurately manage session state, distinguish between intentional pauses and terminations, and avoid sending repeated requests that would cause errors, thereby improving reliability while maintaining request capability.

AI summary
A method for performing an SUPL-based triggered location service, comprising: sending a pause message for a triggered session to a server, starting the triggered session for a triggered location service with the server; and sending a end message to the server if a condition added to the triggered session is satisfied during pause of the triggered session.
