Telecommunications Signaling System Nuisance Call Blocking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current solutions for blocking nuisance calls, such as those generated by automated dialers, are ineffective as they require external applications, are complex for subscribers to configure, and lack access to necessary data, limiting their ability to completely block calls across all types of telecommunications networks.
Innovation Solution
Implementing a system within the network core that captures signaling information to identify and block nuisance calls by associating calling party identifiers with subscriber identifiers, using a combination of subscriber-level and network-level databases, and analytics to determine patterns of nuisance calling behavior.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If external applications are used to block nuisance calls, then call blocking capability is provided, but device complexity increases and ease of operation deteriorates
Solution Approach 1:
The patent introduces a signaling intercepting module as an intermediary component within the network core that captures signaling messages between the switching module and user equipment. This intermediary module analyzes the signaling messages to identify nuisance calls and generates blocking instructions, thereby providing call blocking capability without requiring complex external applications on user devices.
2Reliability
If external applications with simultaneous ring feature are used, then nuisance call identification is attempted, but ease of operation deteriorates and reliability decreases
Solution Approach 1:
The system implements automatic nuisance call identification and blocking without requiring user configuration. The signaling intercepting module automatically captures and analyzes signaling messages, and the processing module automatically generates blocking instructions based on the analysis, eliminating the need for users to manually configure simultaneous ring features or other complex settings.
Solution Approach 2:
The patent performs preliminary analysis of signaling messages during the call setup phase, before the actual call connection is established. By intercepting and analyzing signaling messages early in the call process, the system can identify nuisance calls and prepare blocking instructions in advance, improving blocking effectiveness without requiring user action during the call.
3Reliability
If external applications are used, then some nuisance call blocking is achieved, but loss of information occurs due to lack of access to network data
Solution Approach 1:
The signaling intercepting module is integrated within the network core and can access multiple types of network data including signaling messages, subscriber information, and call details. This universal access to network data enables accurate identification of nuisance calls based on comprehensive information available in the network, rather than limited data accessible only to external applications.

AI summary
Methods, systems, and computer readable media for nuisance call management. In one example, a method includes receiving, at a telecommunications signaling computer system for routing telecommunications signaling messages in a core network of a telecommunications signaling network, a message from a subscriber's user equipment (UE) indicating that the subscriber has flagged a first call as a nuisance call. The method includes storing, in a subscriber-level nuisance call database, an association between a calling party identifier for the calling party and a subscriber identifier for the subscriber. The method includes, in response to a second call from the calling party to the subscriber, blocking, at the telecommunications signaling computer system, the second call using the association between the calling party identifier and the subscriber identifier in the subscriber-level nuisance call database.
