Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users of communication terminals face difficulties in reliably storing and managing subscriber identifiers across multiple address books, leading to effort-intensive backup and transfer processes, with a risk of losing address book entries.
Innovation Solution
A method and SIM card with a detection device that checks for subscriber identifiers in address books, stores them in a predetermined location, and associates attributes, ensuring identifiers are stored at a defined location for easy access and communication connection setup.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple address books are provided by different applications and stored at different memory locations, then the user can store and access subscriber identifiers through different applications, but the user must consider multiple applications for backup and transfer operations, increasing the effort and risk of losing address book entries
Solution Approach 1:
The patent merges multiple address books from different applications into a unified address book structure. The detection device receives subscriber identifiers from any application and stores them in a single centralized address book, eliminating the need for users to manage multiple separate address books for backup and transfer operations.
Solution Approach 2:
The unified address book serves multiple applications simultaneously, providing a universal storage location for subscriber identifiers regardless of which application originally created or accessed the identifier. This multi-functional approach simplifies backup and transfer operations while maintaining compatibility with different applications.
2Reliability
If the user manually stores subscriber identifiers in an address book, then the user has control over the storage process, but the user may fail to store identifiers, leading to loss of phone numbers and inability to establish communication connections
Solution Approach 1:
The detection device automatically performs the storage of subscriber identifiers in the address book without requiring manual user intervention. When the device detects a subscriber identifier during communication operations, it autonomously checks if the identifier exists in the address book and stores it if missing, ensuring reliable storage while reducing user effort.
Solution Approach 2:
The system performs preliminary storage of subscriber identifiers in the address book before communication operations are needed. By proactively detecting and storing identifiers during initial encounters, the system ensures identifiers are available for future use, preventing loss and enabling reliable communication connection establishment.
3Ease of operation
If subscriber identifiers are not stored in an address book, then the user can avoid managing address book entries, but the user experiences loss of phone numbers and inability to easily establish communication connections
Solution Approach 1:
The detection device automatically manages address book entries by detecting subscriber identifiers during communication operations and storing them in the address book without requiring user intervention. This self-service approach ensures identifiers are reliably stored and available while minimizing user management effort.
Solution Approach 2:
The system implements a feedback mechanism where the detection device continuously monitors communication operations, detects subscriber identifiers, and automatically updates the address book accordingly. This closed-loop approach ensures the address book remains synchronized with actual communication usage, maintaining reliability while reducing manual management.
Data Source
AI summary
The method involves establishing a communication link by a subscriber identifier of a communication station. The identifier is received in a detection device of a communication device (101). A determination is made whether the identifier is included in an address book of the communication device. The identifier is stored in the address book when the identifier is not included in the address book so as to establish the communication link. The address book is stored in a subscriber identification module (SIM)-card (109). An independent claim is also included for a communication device comprising a subscriber identification module (SIM)-card and a detection device.
