Method for preventing media-coordinated attacks on emergency networks
The patent US12035138B2 outlines a method and network architecture designed to counter media-coordinated attacks on emergency call networks, specifically targeting the functionality of Emergency Services Routing Proxy (ESRP) elements. The method begins with the first ESRP receiving a session initiation request that deviates from a preconfigured media threshold. This deviation triggers the logging of the request and the sending of an alert notification to other ESRP elements that have subscribed to potential attack notifications. The first ESRP then verifies if there is any transcoding impact on the call routing to the Public Safety Answering Point (PSAP). If no impact is detected, the call is routed directly to the PSAP; otherwise, the call may be downgraded to audio-only if no media-capable PSAP is available.
Further claims detail the operational parameters of the method, including the nature of media-coordinated attacks, such as Denial of Service (DoS) or Distributed Denial of Service (DDoS) attacks. The method also encompasses the prioritization of emergency calls during transcoding processes and the potential integration of machine learning techniques to enhance the handling of media content. Additionally, the network configuration includes multiple ESRP elements, each linked to PSAPs, and may incorporate social media servers or media transcoder components to facilitate improved communication during emergencies. The patent emphasizes a systematic approach to managing emergency calls under threat conditions, ensuring that critical communications remain functional and effective.
