BLE Emergency Help-Seeking via Advertising Packets
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current emergency call functions on intelligent terminals rely on cellular networks, rendering them ineffective in areas without cellular coverage, thus failing to provide timely assistance to users in emergency situations.
Innovation Solution
A Bluetooth Low Energy (BLE)-based communication method that enables electronic devices to communicate without establishing a connection, using the BLE advertising mechanism, allowing for help-seeking signals to be sent even without cellular network access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If cellular network is used for emergency call function, then reliable communication can be achieved, but the system cannot work without cellular network coverage
Solution Approach 1:
The patent introduces Bluetooth Low Energy (BLE) as an intermediary communication mechanism between the terminal and emergency contact persons. BLE advertising packets serve as the mediator that carries emergency information without requiring traditional cellular network infrastructure, thus resolving the contradiction between reliable communication and network environment adaptability.
Solution Approach 2:
The patent changes the communication parameter from cellular network-based to BLE-based advertising mechanism. By utilizing BLE's advertising feature instead of established connection modes, the system achieves both reliability for emergency communication and adaptability to work without cellular network coverage.
2Reliability
If traditional connection-based communication is used, then stable communication can be achieved, but power consumption increases and response time delays
Solution Approach 1:
The patent utilizes BLE advertising mechanism which operates in periodic intervals rather than continuous connection. The advertising packets are sent at specific intervals, allowing the terminal to consume less power while still maintaining the ability to send emergency information reliably when needed.
Solution Approach 2:
The BLE advertising mechanism allows the terminal to autonomously broadcast emergency information without requiring connection establishment procedures. This self-service approach reduces both power consumption and response time while maintaining communication reliability for emergency scenarios.
3Reliability
If connection establishment is required before communication, then communication reliability is improved, but response time increases
Solution Approach 1:
The patent employs BLE advertising packets that are pre-configured and can be transmitted immediately without connection establishment. The advertising mechanism is prepared in advance, allowing emergency information to be broadcast instantly when needed, thus eliminating connection setup time while maintaining communication reliability.

AI summary
This application discloses a Bluetooth low energy-based communication method and a related apparatus. An electronic device sends a help seeking advertising packet on a Bluetooth low energy advertising channel in response to a user operation, where the help seeking advertising packet carries emergency help seeking information. In this application, the electronic device can send the help seeking advertising packet based on Bluetooth low energy, so that a user can seek timely and effective help from another nearby user. When encountering danger, the user can also send the help seeking advertising packet even if there is no cellular network, to ensure safety of the user.
