Secure Profile Activation for Mobile Data Connectivity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Mobile devices often lack a compatible data communications status, particularly when traveling abroad and without Wi-Fi or cellular roaming, hindering the functionality of data communications-enabled applications like taxi-hailing services.
Innovation Solution
A method where a communications-enabled application on a mobile device detects the need for data transmission and requests activation of a secure profile for a cellular network data communications session, enabling data transmission even without an active Wi-Fi connection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the application uses Wi-Fi or cellular connectivity for data transmission, then data communication capability is improved, but the device cannot function when roaming abroad without Wi-Fi or cellular roaming enabled
Solution Approach 1:
The patent introduces a secondary channel using a different radio access technology (RAT) as an intermediary communication path. When the primary channel (Wi-Fi or cellular) is unavailable, the application can transmit data through this secondary channel, ensuring continuous functionality during international roaming without requiring traditional cellular data plans.
2Ease of operation
If the device relies on traditional cellular network connections, then data transmission is enabled, but roaming abroad without cellular roaming enabled blocks communication
Solution Approach 1:
The patent implements multi-functionality by enabling the application to operate across multiple radio access technologies. The system can switch between primary and secondary channels with different RATs, making the application universally adaptable to various network conditions including international roaming scenarios where traditional cellular networks are unavailable.
3Productivity
If the application requires a data communications connection to function fully, then application capabilities are improved, but the device cannot access these capabilities without internet connection
Solution Approach 1:
The patent establishes a secondary communication channel in advance as a backup mechanism. This preliminary action ensures that when the primary internet connection becomes unavailable during international travel, the application already has an alternative pathway ready to maintain its core functionalities such as location broadcasting and taxi requests.

AI summary
Methods for operating a communications-enabled application, controlling a secure profile via an operating system, and operating a cellular network are provided. Operating a communications-enable application includes detecting a need for data transmission when the mobile device has a communications status which is incompatible with the need and sending a request to activate a secure profile. Controlling the secure profile includes receiving a request from an application to have data session access via a secure profile and activating a data session utilising a secure profile. Operating the cellular network includes receiving a request to establish a cellular network data communications session from a mobile device including the communications-enabled application and establishing a data session with the mobile device using the secure profile. A mobile device and cellular network for performing the methods are also provided.
