Unread Short Message Backup via Subscriber Identity Card Synchronization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Mobile communication terminals face poor user experience due to capacity limitations and performance issues when storing short messages, leading to potential loss of unread messages upon device replacement.
Innovation Solution
A method and device that synchronize unread short messages between terminal storage and subscriber identity card, allowing backup and deletion of messages when read or deleted, with periodic initialization synchronization and capacity checks to manage storage efficiently.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the new short message is stored in the subscriber identity card, then the user can access messages on different devices, but the capacity limit and performance influence of the subscriber identity card would exist
Solution Approach 1:
The patent divides the storage system into two segments: terminal storage for primary message storage and subscriber identity card for backup storage. This segmentation allows each storage medium to be optimized for its specific role, with the terminal providing large capacity and the card providing portability and cross-device access.
Solution Approach 2:
The patent introduces a message management control module as an intermediary that coordinates between the terminal storage and subscriber identity card. This mediator manages the backup and synchronization processes, ensuring that messages are properly stored in both locations without overwhelming either storage medium.
2Quantity of substance
If the new short message is stored in the terminal storage, then the capacity is relatively big, but if the terminal is replaced, the user would lose the new short message
Solution Approach 1:
The patent implements preliminary backup action by automatically copying new short messages from terminal storage to the subscriber identity card before device replacement occurs. This preliminary action ensures that messages are secured in a portable storage medium that can be transferred to a new terminal.
Solution Approach 2:
The patent creates a protective backup copy of messages in the subscriber identity card, which serves as a cushion against data loss during terminal replacement. This beforehand cushioning ensures that even if the original terminal is lost or replaced, the messages remain safe and recoverable.
3Adaptability or versatility
If the short message is not stored in the protocol stack and directly reported to the short message management control module, then the storage solution can be flexibility controlled, but if stored in the subscriber identity card, the capacity limit would exist
Solution Approach 1:
The patent implements a dynamic storage strategy where the system automatically determines whether to store messages in terminal storage or subscriber identity card based on current capacity conditions. This dynamic approach allows the system to adapt to changing storage requirements and optimize the use of available capacity in both storage mediums.

AI summary
The present invention provides a method and a device for backing up an unread short message, both of which can store a new short message received by a mobile communication terminal in a terminal storage and back up the new short message to a subscriber identity card, and delete, when a user reads or deletes an unread short message stored in the terminal storage, a backup unread short message, which stored in the subscriber identity card, corresponding to the new short message. The method and the device of the present invention can synchronize the unread short message in the terminal storage and the subscriber identity card, so that the user will not lose the unread short message even when changing the mobile communication terminal.
