Data Card OTA Service Customization via Remote Configuration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current data card systems lack flexibility in customizing application services, requiring system upgrades and increasing user experience issues and manufacturer costs due to inflexible customization methods.
Innovation Solution
A system and method utilizing Over-The-Air (OTA) technology, where a data card sends customization requests to an OTA server, which returns configuration commands for updating application services, allowing for remote and rapid customization without physical return to the factory, using an OTA proxy module and service database to manage and store configuration information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the original data card system uses a configuration-file based customization strategy requiring system upgrades, then application service customization is achieved, but customization flexibility is poor and repeated test expenses increase
Solution Approach 1:
The patent replaces the traditional mechanical system approach (physical system upgrades requiring factory returns and re-testing) with an information-based OTA (Over-The-Air) technology system. Configuration commands are transmitted wirelessly to data cards, enabling remote customization without physical system upgrades or repeated testing, thus resolving the contradiction between customization adaptability and system complexity.
2Adaptability or versatility
If the data card system requires physical return to factory for customization, then service requirements are met, but user experience deteriorates and manufacturing costs increase
Solution Approach 1:
The patent enables self-service customization where data cards automatically receive and execute configuration commands via OTA technology. Users do not need to physically return to the factory; the system performs customization autonomously through wireless configuration updates, dramatically improving ease of operation while maintaining full customization capability.
3Adaptability or versatility
If the original customization method is used, then application services can be customized, but repeated test expenses and manufacturing investment increase
Solution Approach 1:
The patent extracts the customization process from the physical manufacturing environment and transfers it to a remote information-based system. Configuration commands are sent via OTA technology, eliminating the need for repeated physical testing and factory returns, thus reducing manufacturing test expenses and energy loss while preserving full customization capability.

AI summary
The present invention provides a method for customizing application services of a data card. The system comprises a data card and an over-the-air server. The method comprises: the data card sending an application service customization request to the over-the-air server when an application service is required to be customized; and the over-the-air server receiving the application service customization request, and then returning a configuration command corresponding to configuration information to the data card if it is determined that an operation of the data card to request customization of the application service is valid according to the stored and managed configuration information of all application services supported by the data card. The data card in accordance with the present invention can complete customization of the application service by modifying a configuration file of the data card through an OTA proxy module according to a service configuration command sent by the OTA server, thus not only the upgrade cost of the manufacturer of the data card is decreased, but also investment of the user is saved.
