Communication Connection Control for Unsolicited Call Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current solutions for preventing unsolicited communications (SPIT/UC) in VoIP and legacy networks are inadequate, as they primarily focus on VoIP networks and require changes in SIP signaling, affecting users across different network types and raising legal and liability concerns.
Innovation Solution
A communication connection establishment control system that uses supplementary services like blacklisting, whitelisting, authentication requests, and Turing tests to manage unsolicited communications across various networks, allowing users to create personalized profiles without requiring changes in SIP signaling or network infrastructure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If existing SPIT/UC prevention solutions are implemented, then VoIP network protection is improved, but network compatibility and ease of operation deteriorate due to requiring SIP signaling changes and affecting users across different network types
Solution Approach 1:
The patent segments the SPIT/UC prevention functionality into a separate, standalone module that operates independently of SIP signaling. This segmentation allows the solution to be applied universally across different network types (VoIP, PSTN, etc.) without requiring changes to existing signaling protocols, thereby maintaining network compatibility while providing effective protection.
Solution Approach 2:
The invention creates a universal SPIT/UC prevention mechanism that functions across multiple network types and protocols. By designing a protocol-independent solution that works with VoIP, PSTN, and other networks, it achieves multi-functionality without requiring network-specific modifications, thus improving ease of operation and compatibility.
2Reliability
If protocol-specific SPIT/UC prevention measures are implemented, then protection effectiveness is improved, but device complexity and difficulty of detecting and measuring increase due to requiring changes in SIP signaling
Solution Approach 1:
The patent extracts the SPIT/UC prevention functionality from the SIP signaling protocol itself, creating a separate, independent mechanism. This extraction eliminates the need to modify complex SIP signaling procedures, thereby reducing device complexity and infrastructure changes while maintaining effective protection through a dedicated prevention module.
3Reliability
If comprehensive authentication and verification mechanisms are implemented, then SPIT/UC prevention is improved, but loss of time increases due to additional authentication steps for legitimate users
Solution Approach 1:
The patent implements partial authentication mechanisms that apply only to suspicious or unsolicited calls rather than all calls. By using heuristics and behavioral analysis to identify potential SPIT/UC attempts, the system applies authentication only when necessary, thereby preventing unsolicited communications while minimizing time loss for legitimate users who do not trigger the authentication mechanism.

AI summary
There is proposed a mechanism for controlling a communication connection establishment to a subscriber using service comprising blacklisting, whitelisting, authentication request and/or Turing test for unsolicited communications prevention. Furthermore, there is proposed a management system used to configure a corresponding communication connection establishment control on the basis of an interface for the subscriber for defining a personalized communication connection establishment control profile.
