UICC Update Confirmation via SMS Routing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for updating universal integrated circuit cards (UICCs) across mobile wireless communication networks lack confirmation mechanisms, making it difficult to determine if updates are successful or if failures occur, which can lead to malfunctions in mobile devices.
Innovation Solution
Implementing a proof-of-receipt mechanism using SMS messages to confirm the receipt and integrity of update triggers, allowing the UICC update server to verify successful updates and notify users or administrators of failures, and waking up associated mobile device applications to provide status notifications.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional UICC update methods are used without confirmation mechanisms, then the update process is simpler and faster, but it becomes impossible to verify whether updates were successful or if failures occurred
Solution Approach 1:
The patent implements a feedback mechanism where the UICC sends an SMS message back to the network to confirm receipt of update triggers. This feedback loop allows the network to verify whether the UICC successfully received and processed update commands, resolving the contradiction by providing reliable confirmation without significantly increasing system complexity.
Solution Approach 2:
The patent introduces an intermediary message routing system that directs SMS messages between the network, baseband processor, and UICC. This intermediary layer manages the complexity of message routing internally while presenting a simple interface to users, thereby achieving reliable update confirmation without exposing system complexity to end users.
2Reliability
If proof-of-receipt mechanism is implemented using SMS messages, then update confirmation reliability is improved, but message routing complexity increases due to baseband processor involvement
Solution Approach 1:
The patent leverages the existing SMS messaging capability of the baseband processor for a dual purpose: traditional voice/SMS communication and UICC update confirmation. By making the baseband processor multi-functional, the patent achieves reliable update verification without adding dedicated hardware or significantly increasing system complexity.
3Ease of operation
If SMS messages are used for UICC update confirmation, then user notification capability is improved, but network resource consumption increases
Solution Approach 1:
The patent uses SMS messages selectively only when UICC updates are triggered or status changes occur, rather than continuously. This partial action approach provides effective user notification capability while minimizing unnecessary network resource consumption, resolving the contradiction between notification effectiveness and energy efficiency.
Data Source
AI summary
Information regarding the status of an update to a universal integrated circuit card (UICC) being performed across a mobile wireless communication network is provided to a server involved in the update process and/or to a user of the mobile communication device having the UICC. The UICC update server sends an update trigger to the mobile communication device, and the UICC initiates establishment of a communication link to receive the update. The UICC further causes a baseband processor of the mobile communication device to send a proof-of-receipt of the update trigger by short message service (SMS) messaging back to the update server. Additionally or alternatively, the UICC causes the baseband processor to send a wakeup message to a mobile device application executing on the mobile device. The wakeup message includes status information relating to the UICC update which can be provided to a user of the mobile device.
