Satellite Help-Seeking Information Sharing for Faster Rescue Coordination
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing methods for sending help-seeking information through satellite communication often result in delayed rescue responses due to the help seeker's inability to timely receive reply information from rescuers.
Innovation Solution
A method for generating and sending target shared information by an electronic device that combines help-seeking information from multiple terminals within a time and distance threshold, allowing nearby help seekers to gather and increase rescue probability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the help seeker waits for reply information from the rescuer through satellite communication, then the rescue response can be received, but the rescue time is delayed due to inability to pull reply information in time
Solution Approach 1:
The patent applies preliminary action by proactively sending help-seeking information to multiple potential rescuers before actual rescue is needed. The system pre-establishes communication with rescuers and pre-sends location and situation information, so that when rescue is required, the information is already available and rescuers can respond immediately without waiting for the help seeker to actively pull reply information.
Solution Approach 2:
The patent uses an intermediary mechanism by introducing a message forwarding system that acts as a mediator between help seekers and rescuers. The system automatically forwards help-seeking information to multiple rescuers and manages the communication flow, eliminating the need for the help seeker to manually pull reply information and reducing time delays.
2Reliability
If help-seeking information is sent to multiple rescuers, then the probability of rescue increases, but the satellite communication frequency and resource usage increase
Solution Approach 1:
The patent applies partial action by sending help-seeking information to a selective subset of rescuers rather than all possible rescuers. The system evaluates multiple factors including location proximity, rescuer availability, and historical response rates to determine which rescuers to contact, thereby reducing satellite communication frequency while maintaining high rescue probability.
Solution Approach 2:
The patent uses parameter changes by dynamically adjusting communication parameters such as message transmission timing, frequency, and target selection based on real-time conditions. The system monitors satellite signal quality, rescuer response status, and help seeker location changes to optimize communication parameters and reduce energy consumption while maintaining effective rescue coordination.

AI summary
A method for sending target shared information and an electronic device are disclosed. The method includes: separately receiving, through a satellite, first help-seeking information sent by a first terminal and second help-seeking information sent by a second terminal, where the first help-seeking information includes first help-seeking content, first sending time, and first location information, and the second help-seeking information includes second help-seeking content, second sending time, and second location information; when a time difference does not exceed first preset time and a distance difference does not exceed a preset distance, generating the target shared information, where the target shared information indicates help-seeking information of the first terminal and help-seeking information of the second terminal, the time difference is an absolute value of a difference between the first sending time and the second sending time, and the distance difference is an absolute value of a distance difference between a location indicated by the first location information and a location indicated by the second location information; and sending the target shared information to a target terminal, where the target terminal is the first terminal and/or the second terminal. According to the method, a probability of rescuing a help seeker can be increased.
