Mobile Data Capture via Local Storage and Delayed Upload
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for capturing data from mobile devices in wireless networks, particularly in off-network environments, face challenges such as detectability and tampering risks, especially during ProSe communication, where traditional interception is not possible, and data upload can lead to behavioral changes and increased battery consumption.
Innovation Solution
The system involves receiving data capture configuration information, storing data locally on mobile devices during ProSe communication, and uploading it when network access is regained, with features like intentional delay and distributed or duplicated recording to minimize detectability and ensure data integrity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional interception methods are used in off-network environments, then data capture is impossible during ProSe communication, but implementing local storage and delayed upload increases detectability and battery consumption
Solution Approach 1:
The system performs preliminary actions by storing data capture configuration information and enabling local data storage capabilities before entering off-network environments. This allows the mobile device to be prepared for data capture without triggering network-based detection mechanisms, resolving the contradiction between capturing data and avoiding detectability.
Solution Approach 2:
The patent introduces an intermediary mechanism where data is first stored locally on the mobile device and then uploaded to the network through a controlled process. This intermediary local storage step enables data capture in off-network environments while managing detectability by controlling when and how data is transmitted to the network.
2Reliability
If data is continuously monitored and uploaded during group communication, then data integrity is maintained, but battery consumption increases
Solution Approach 1:
The system implements periodic action by uploading stored data only when specific conditions are met, such as when the mobile device regains network access. This conditional periodic upload mechanism maintains data integrity by ensuring data is transmitted when possible while significantly reducing battery consumption compared to continuous monitoring and uploading.
3Reliability
If distributed recording is implemented across multiple devices, then data capture reliability improves, but system complexity increases
Solution Approach 1:
The patent applies segmentation by distributing the data capture function across multiple mobile devices participating in group communication. Each device independently stores data elements according to configuration information, dividing the overall data capture task into separate segments that can be executed autonomously by each device, thereby improving reliability without requiring complex centralized coordination.

AI summary
Some aspects of what is described here relate to systems, devices, and computer-implemented methods for capturing data related to a mobile device in a wireless network. In one example, a method may include receiving, at a first mobile device, data capture configuration information from a wireless network. The data capture configuration information indicates a target mobile device from which data is to be captured during group communication between the first mobile device and the target mobile device. Thereafter, in response to detecting a group communication between the first mobile device and the target mobile device, a data element is stored in a local memory of the first mobile device. The data element includes information from the group communication between the first mobile device and the target mobile device. The data element is sent to the wireless network.
