Call Filter System for Telemarketer Identification and Blocking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional phone systems fail to effectively prevent unwanted telemarketer calls, despite registration on Do Not Call lists, as telemarketers continue to contact subscribers, disrupting communication and requiring time to manage unwanted voicemails.
Innovation Solution
A call filter system that analyzes call information to identify and list phone numbers associated with telemarketing activity, using persistence metrics and reputation feedback to generate a list of unwanted callers, allowing subscribers to set call handling instructions for blocking or notification of such calls.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If phone numbers are made publicly available, then legitimate persons can easily obtain them, but telemarketers can also access and call these numbers
Solution Approach 1:
The patent segments the phone number registry into two distinct components: a public directory containing basic contact information that is easily accessible, and a separate Do Not Call list that contains phone numbers of subscribers who wish to avoid telemarketing calls. This segmentation allows legitimate access while providing protection mechanisms for those who opt out.
Solution Approach 2:
The patent introduces an intermediary mechanism (the Do Not Call list and associated blocking system) that mediates between the public's right to access phone numbers and the subscriber's right to privacy and freedom from unwanted calls. This intermediary layer enables call filtering without compromising the public availability of directory information.
2Object-affected harmful factors
If phone numbers are registered as unlisted, then telemarketers cannot easily obtain them, but friends of the subscriber also cannot obtain the phone number
Solution Approach 1:
The patent divides the phone number accessibility into multiple layers: fully public directory access for general information, unlisted status for those seeking privacy, and the Do Not Call list for those specifically wanting to block telemarketers while maintaining public directory listing. This allows subscribers to choose different levels of visibility and protection.
Solution Approach 2:
The patent applies different accessibility qualities to different aspects of phone number information. The directory listing can remain public for legitimate access by friends and family, while simultaneously applying Do Not Call protection to block telemarketers. This local differentiation of quality allows simultaneous public availability and protection.
3Object-affected harmful factors
If Do Not Call list is implemented, then telemarketers should not call registered numbers, but telemarketers continue to call without regard to DNC registration
Solution Approach 1:
The patent implements feedback mechanisms where call monitoring systems track calls to Do Not Call registered numbers and identify telemarketers who violate the DNC list. This feedback enables the system to learn from violations and improve enforcement, making the Do Not Call list more effective over time.
Solution Approach 2:
The patent performs preliminary actions by pre-registering phone numbers on the Do Not Call list before unwanted calls occur. The system proactively blocks calls from known telemarketers and maintains a database of violators, preventing future violations rather than merely reacting to them.
Data Source
AI summary
An analyzer resource receives call information about outbound phone calls from multiple phone numbers to target phone numbers in a phone network. The analyzer resource analyzes the call information to detect likely unwanted call activity. Based on the analyzing, the analyzer resource produces a list of phone numbers from which one or more entities originate unwanted calls to the subscribers in the phone network.
