Direct Access Mailbox Control via Automated Caller Store
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current telecommunications systems lack the ability for users to control who can access their audio-visual mailboxes directly, allowing or blocking access without disturbing the called party, and existing solutions do not provide adequate control mechanisms.
Innovation Solution
A method and system where a store maintains entries of users allowed or not allowed to send audio-visual communications directly to a mailbox, with automated store modifications based on predefined rules and signals, allowing users to control direct access by checking and updating these entries upon sending or receiving communications.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If direct voice mail access is implemented allowing callers to connect with the mailbox without disturbing the called party, then convenience and privacy are improved, but control over who can access the mailbox deteriorates
Solution Approach 1:
The system automatically maintains the store of allowed callers by updating it whenever the called party makes a call. The called party simply needs to dial the store update number, and the system automatically adds the caller to the allowed list without requiring manual configuration or complex control mechanisms from the caller.
Solution Approach 2:
The system provides feedback to the called party by automatically updating the store based on call records. When a call is made, the system feedbacks the caller's identity to the store maintenance mechanism, which then updates the allowed callers list accordingly, creating a closed-loop control system.
2Measurement precision
If manual control lists are maintained by subscribers to control direct access, then access control precision is improved, but operation complexity and time consumption worsen
Solution Approach 1:
The system performs preliminary action by automatically updating the store before the actual access decision is made. The store is maintained in advance with the latest information about allowed callers, so when a direct access request occurs, the decision can be made immediately without requiring manual checking or updating at the moment of access.
Solution Approach 2:
The system serves itself by automatically maintaining the access control store based on call records. Instead of requiring manual intervention to update the allowed callers list, the system uses the call data itself to trigger automatic store updates, eliminating the need for manual maintenance operations.
3Ease of operation
If automated store modification procedures are implemented, then ease of operation is improved, but system complexity worsens
Solution Approach 1:
The store acts as an intermediary component between the calling party, the called party, and the access control logic. It maintains the state of allowed callers and mediates the access decisions by providing the necessary information to the system that determines whether to allow or block the direct mailbox access request.
Data Source
AI summary
A communication system (1) in which a user (A) can elect to leave a message directly in the mailbox (11a) of another user (B) without calling or disturbing user (B). A store (database 7) is generated and maintained which identifies those users who are allowed direct access to the mailbox of user (B). The store is automatically updated whenever user (B) sends a communication to other users.
