Managing Partial Subscription Data on Mobile Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for managing subscription data in mobile devices do not allow users to identify or manage partially or incompletely loaded subscriptions, leading to potential data transmission issues during device resale, where previous owners want to ensure data deletion and new owners do not receive unwanted or unpersonalized subscriptions.
Innovation Solution
A method that establishes a communication connection to determine the presence of partially or incompletely loaded subscription data on a device and allows for management actions such as deletion or adjustment, using protocols like TCP/IP, NFC, or WLAN, ensuring secure and reliable data handling, particularly relevant for device resale scenarios.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If subscription data are transmitted OTA to be stored on SIM/UICC, then multiple subscriptions can be stored and updated, but users cannot identify or manage partially loaded subscriptions leading to data transmission issues during device resale
Solution Approach 1:
The patent introduces a feedback mechanism where the mobile device queries the server to obtain information about whether partial subscription data exists, and the server responds with the status of subscription data completion. This feedback loop enables users to identify and manage partial subscription data appropriately.
Solution Approach 2:
The server acts as an intermediary between the mobile device and the subscription data storage system. It maintains information about the completion status of subscription data and provides this information to the mobile device, enabling users to make informed decisions about data management during device resale.
2Ease of operation
If previous owners want to ensure data deletion during device resale, then user control over subscription data is improved, but new owners may receive unwanted or unpersonalized subscriptions that were not fully transmitted
Solution Approach 1:
The patent enables preliminary action by allowing the previous owner to check the status of subscription data transmission before completing the device resale. The user can query the server in advance to determine whether partial subscription data exists and take appropriate actions such as deleting or completing the data transmission before the device changes hands.
Solution Approach 2:
The system enables self-service by allowing users to independently check and manage their own subscription data status through the mobile device. Users can query the server, identify partial data, and perform management actions without requiring assistance from the seller or buyer, thus improving both user control and transmission reliability.
3Device complexity
If no information is provided about partial profiles on remote servers, then server complexity is reduced, but users cannot verify complete data availability before device resale
Solution Approach 1:
The patent extracts only the essential information about subscription data completion status from the server and transmits it to the mobile device. Instead of providing comprehensive server information, the system extracts and communicates only the critical completion status, thereby maintaining low server complexity while enabling users to detect partial profile availability.
Data Source
AI summary
A method for managing partly and/or incompletely loaded subscription data is provided for a mobile device and/or another device. A communication connection is established between the mobile device and the other device. Then, it is ascertained whether the partly and/or incompletely loaded subscription data is available on the other device, and a managing action is carried out on the partly and/or incompletely loaded subscription data.
