Call Processing System with Shared Suspicious Number Database
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users in nuisance call blocking services are unaware that a received call is from a suspicious number unless they have previously received the call, leading to potential missed warnings for suspicious calls.
Innovation Solution
A call processing system that allows users to register suspicious call numbers, sharing this information across all users, and alerts incoming terminals before connecting calls from registered suspicious numbers, even if the user has not previously received a call from that number.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If users register nuisance calls individually after receiving them, then each user can block known nuisance numbers, but users remain unaware of suspicious calls from numbers they have not previously received calls from
Solution Approach 1:
The patent merges individual user nuisance call registration data into a shared database accessible by all users. When one user registers a suspicious number, this information is immediately available to all other users in the network, enabling collective awareness and protection against nuisance calls without requiring each user to personally encounter the suspicious number first.
Solution Approach 2:
The system implements a feedback mechanism where users who receive nuisance calls can report them, and this feedback is automatically shared with the entire user base. The shared database continuously updates with new suspicious numbers, providing real-time feedback to all users about emerging threats without requiring dedicated feedback apparatuses at each user endpoint.
2Adaptability or versatility
If suspicious call information is shared across all users, then all users benefit from collective awareness, but the system requires a shared database infrastructure
Solution Approach 1:
The patent makes the database infrastructure universal by implementing it at the network operator level rather than at individual user devices. The shared database serves all users simultaneously, providing multi-functional protection across the entire network. This approach eliminates the need for each user to maintain separate databases while still providing comprehensive collective protection against nuisance calls.

AI summary
A call processing server 10 includes a registration unit 12 that receives a registration request of a suspicious call number from a user receiving a suspicious call to register the suspicious call number in a subscriber information storage unit 22, and a call processing unit 11 that refers to the subscriber information storage unit 22 to control an incoming call, in which the call processing unit 11 transmits, when an outgoing source of a call is the suspicious call number registered in the subscriber information storage unit 22, an alert guidance to an incoming destination terminal 5 before connecting the call, and the suspicious call number registered in the subscriber information storage unit 22 is shared by all users set in the subscriber information storage unit 22.
