Bluetooth Device Search Using Pre-Obtained Location Data
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing device search methods in electronic devices, such as those using GPS positioning, result in high power consumption due to frequent enabling of location reporting services, leading to low efficiency in finding lost devices.
Innovation Solution
A method where a second electronic device scans a Bluetooth broadcast from a first offline device to obtain location information, using pre-obtained location data from other applications on the second device, reducing the need for frequent GPS invocations and network connections to report location information in batches.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the online device frequently enables location reporting service to report location information multiple times, then the efficiency of searching for lost device is improved, but the power consumption of the online device increases
Solution Approach 1:
The second electronic device pre-obtains location information through positioning services before receiving Bluetooth broadcasts. When a Bluetooth broadcast is received from an offline device, the device can immediately use the pre-obtained location information for reporting without needing to invoke the positioning service at the moment of broadcast reception, thus reducing power consumption while maintaining search efficiency
Solution Approach 2:
The second electronic device uses location information obtained by one application to serve multiple purposes - both for normal application functionality and for Bluetooth broadcast reporting. This copying of location information between different functional contexts eliminates the need for duplicate positioning service invocations, reducing power consumption while enabling multiple location reports
2Use of energy by moving object
If the online device uses location information from one application to report Bluetooth broadcasts, then power consumption is reduced, but the ability to report location information multiple times is limited
Solution Approach 1:
The location information obtained by the first application on the second electronic device is made universally applicable - it serves both the original purpose of the first application and the Bluetooth broadcast reporting function. This multi-functionality allows the device to report location information multiple times using a single positioning service invocation, thus reducing power consumption while maintaining high reporting frequency
Solution Approach 2:
The patent merges the location information acquisition function with the Bluetooth broadcast reporting function. By combining these two functions into a unified approach where one positioning service call serves both purposes, the system achieves efficient power usage while enabling multiple location reports for search operations

AI summary
A first application of a second electronic device obtains at least one piece of location information. After the first application obtains the at least one piece of location information, the second electronic device scans a first BLUETOOTH broadcast from a first electronic device. The second electronic device obtains first location information based on the first BLUETOOTH broadcast, where the first location information is at least one of the at least one piece of location information. The second electronic device reports the first location information to a server. The second electronic device may use location information obtained by another application on the second electronic device. When the second electronic device obtains the BLUETOOTH broadcast through scanning, the second electronic device does not need to frequently invoke a second application to obtain location information.
