Relay Device Emergency Broadcast Format Conversion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
During emergency situations like natural disasters or security incidents, cellular networks become overloaded, making it difficult for people to receive timely updates, and existing solutions struggle to effectively relay critical information to multiple mobile terminals without overwhelming the network.
Innovation Solution
A relay device and method that receive a broadcast signal containing emergency information, convert it into a different format, and transmit it to multiple mobile terminals via an unencrypted communication channel, using a processor to provide the information in a webpage format, and optionally include feedback elements, while connecting to a network to provide unique resource identifiers for displaying the information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If cellular networks are used to broadcast emergency information, then information can be delivered to mobile terminals, but the network becomes overloaded and unable to deliver information effectively
Solution Approach 1:
The patent introduces a relay device as an intermediary between the cellular network and mobile terminals. The relay device receives emergency information via broadcast signal, converts it to a different format, and transmits it to mobile terminals through a communication channel. This intermediary approach prevents network overload by handling information conversion and distribution locally, rather than requiring all mobile terminals to communicate directly with the cellular network infrastructure.
2Ease of operation
If emergency information is converted to a different format for mobile terminals, then information can be displayed effectively, but additional processing complexity is required
Solution Approach 1:
The relay device changes the format parameter of emergency information from broadcast signal format to a mobile terminal-compatible format (such as webpage format). This parameter transformation enables the information to be displayed effectively on mobile devices while the processing is automated and standardized, managing the complexity through systematic conversion rather than manual intervention.
3Loss of information
If broadcast signals are used to transmit emergency information, then information can be received by relay devices, but the original format may not be compatible with mobile terminals
Solution Approach 1:
The relay device transforms the format parameter of received broadcast signals into a compatible format for mobile terminals. This ensures that the complete emergency information is preserved from the broadcast source while adapting it to be displayable and usable on mobile device platforms, resolving the compatibility issue between different communication formats.
