Telecommunication Service Access Control for Denial-of-Service Mitigation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Telecommunication networks face denial of service attacks that degrade or prevent access to priority services like e911 and WPS, due to unauthorized access attempts that congest network components.
Innovation Solution
Implement a system with a hacking mitigation engine that monitors access request failures, determines excessive failure rates, and blocks subsequent requests from user devices based on cell global identifiers or geographic locations to mitigate such attacks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the network allows unrestricted access to priority services, then service availability is improved, but network congestion and denial of service attacks worsen
Solution Approach 1:
The patent introduces an intermediary authentication system between user devices and priority telecommunication services. This intermediary verifies device authorization status before allowing access to services like e911 and WPS, thereby preventing unauthorized access attempts that cause network congestion while maintaining service availability for authorized users.
2Object-affected harmful factors
If authentication checks are performed for every access request, then security against denial of service attacks is improved, but network traffic processing time worsens
Solution Approach 1:
The patent implements preliminary authentication by obtaining and storing authorization status information for user devices before they attempt to access priority services. The system pre- verifies whether devices are authorized to access services like e911 and WPS, so that during actual service access attempts, the authentication check is already complete or can be quickly validated, reducing processing time while maintaining security.
3Object-affected harmful factors
If the network blocks unauthorized access attempts, then network congestion is reduced, but legitimate access requests may be mistakenly blocked
Solution Approach 1:
The patent implements a feedback mechanism where the system continuously monitors access patterns and authorization status of user devices. When access requests are received, the system checks against stored authorization information and adjusts blocking decisions based on this feedback. This allows the system to learn from access patterns and improve its ability to distinguish between unauthorized attack traffic and legitimate requests, reducing false positives while maintaining congestion control.

AI summary
Systems and methods are provided for mitigating undesirable service disruptions in a communications network. Based on a determination that an access failure rate exceeds a threshold, it may be determined that a particular service is degraded or that a requesting user device is not authorized to access the service. One or more mitigation protocols may be used to block subsequent attempts by the requesting user device, a set of user devices associated with the requesting user device, or an area associated with the requesting user device to request access to the service.
