Mobile Device Location History Storage and Periodic Transmission
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Continuous data transmission of a mobile device's geographic location to geographic locating services drains the battery, reducing battery life and wasting energy, as existing methods do not efficiently manage the frequency of data transmission.
Innovation Solution
A method where a mobile device determines and stores its geographic location history locally and transmits it to a server at longer intervals based on whether it is moving or stationary, reducing the frequency of data transmission and conserving battery life by using cellular, WiFi, or GPS signals.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If geographic location is continuously determined and transmitted to server, then location accuracy and service reliability are improved, but battery consumption increases and battery life decreases
Solution Approach 1:
The patent implements periodic action by determining geographic location at fixed time intervals rather than continuously, and transmitting location data at scheduled intervals. The system stores location history locally and transmits periodically, which reduces battery consumption while maintaining service reliability through intermittent updates.
Solution Approach 2:
The patent applies preliminary action by storing geographic location data in local memory before transmission is needed. The system pre-accumulates location history and transmits batches of data at scheduled times, eliminating the need for continuous transmission and reducing energy consumption while ensuring data availability for location services.
2Productivity
If geographic location is continuously transmitted to server, then location service functionality is improved, but energy waste increases
Solution Approach 1:
The system transmits location data periodically rather than continuously, with configurable transmission intervals. This periodic transmission maintains location service functionality by providing updated location information at regular intervals while significantly reducing energy waste associated with continuous data transmission.
Solution Approach 2:
The patent extracts only necessary location data for transmission by storing comprehensive location history locally and selectively transmitting data based on predetermined criteria such as time intervals or location changes. This extraction approach maintains service functionality while minimizing energy waste by transmitting only essential information.
3Loss of time
If location data is transmitted frequently, then service responsiveness is improved, but battery life is reduced
Solution Approach 1:
The system implements periodic action with configurable transmission intervals that balance service responsiveness with battery conservation. By transmitting location data at scheduled intervals rather than continuously, the system maintains adequate service responsiveness while extending battery life through reduced transmission frequency.
Solution Approach 2:
The patent applies dynamics by adjusting transmission intervals based on device state (moving vs. stationary). When the device is moving, location is determined and transmitted more frequently to maintain service responsiveness. When stationary, transmission interval increases to conserve battery life, dynamically adapting to operational conditions.

AI summary
Systems and methods for providing a geographic location of a mobile device are provided. In one aspect, a method includes determining a geographic location of the mobile device. The method also includes storing the determined geographic location in a geographic location history in a local memory of the mobile device. The geographic location of the mobile device is determined and stored in the geographic location history at a first time interval. The method also includes providing the geographic location history to a server at a second time interval. The second time interval is longer than the first time interval.
