Wireless Number Presence Analysis for Spoofed Call Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication networks lack a reliable method to detect and block spoofed phone numbers from off-network sources, particularly in cases where the spoofed numbers are from other wireless carriers, leading to a high incidence of nuisance traffic events such as robocalls and spam texts, which negatively impact subscriber experience and network security.
Innovation Solution
Implementing a system where wireless carriers share roaming status information among themselves, either through a third-party detection service or direct communication, to verify the legitimacy of incoming calls by checking if the phone number is registered with the same network at the time of the call, with optional subscriber consent and privacy protections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If wireless carriers implement a system to share roaming status information and detect spoofed phone numbers, then the detection reliability of nuisance traffic events is improved, but the device complexity and operational complexity increase due to the need for inter-carrier communication protocols and data sharing mechanisms
Solution Approach 1:
The patent introduces a third-party detection service as an intermediary that facilitates information sharing between wireless carriers. This mediator handles the complexity of inter-carrier communication protocols and data sharing mechanisms, allowing carriers to benefit from improved detection reliability without directly managing the complex integration of multiple carrier systems. The detection service acts as a neutral platform that standardizes the exchange of roaming status information.
2Measurement precision
If the system performs presence analysis of wireless user endpoint devices to verify communication validity, then the accuracy of nuisance traffic event detection is improved, but the loss of subscriber privacy information increases due to the collection and sharing of roaming status data
Solution Approach 1:
The patent extracts only the specific piece of information needed for detection purposes - the roaming status - from the broader subscriber profile. By taking out only the necessary data element (presence/roaming status) rather than comprehensive subscriber information, the system achieves detection accuracy while minimizing privacy intrusion. This selective data extraction allows verification of communication validity without collecting or sharing sensitive subscriber personal information.
Solution Approach 2:
The system applies local quality by treating roaming status information differently from other subscriber data. The roaming status is handled as a specific, limited-scope data element that is shared only when needed for detection purposes, rather than treating all subscriber information uniformly. This localized approach to data handling maintains detection accuracy for specific scenarios while preserving broader subscriber privacy.
3Speed
If wireless carriers implement real-time verification of phone number registration status, then the speed of nuisance traffic event detection is improved, but the loss of time for legitimate communications increases due to additional verification steps
Solution Approach 1:
The patent implements preliminary action by having wireless carriers pre-share and maintain roaming status information in advance of actual communication events. The detection service is pre-configured with the necessary verification capabilities and data structures, so when a communication event occurs, the system can quickly verify against pre-existing information without requiring real-time data collection or complex on-demand processing. This advance preparation enables fast detection while minimizing disruption to legitimate communications.

AI summary
A processing system may determine a nuisance traffic event. The processing system may receive from a first entity a request to determine a status of a wireless user endpoint device associated with a wireless phone number, wherein the status comprises a determination as to a validity of a subject communication associated with the wireless phone number, perform a presence analysis of the wireless user endpoint device based on the wireless phone number, and respond to the request by providing an indication as to the validity of the subject communication associated with the wireless phone number back to the first entity.
