The method further includes extracting, by the NF and from the authentication response message, a subscription identifier and an indicator of an authentication result for the UE. The method further includes storing, by the NF and in an AMF location service validation database, the subscription identifier and the indicator of the authentication result for the UE. The method further includes receiving, by the NF, an AMF location service message and using at least one of a subscription identifier extracted from the AMF location service message and contents of the AMF location service validation database, to classify the AMF location service message as a location tracking or DoS attack. The method further includes preventing the location tracking or DoS attack."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Methods, systems, and computer readable media for mitigating location tracking and denial of service (DoS) attacks that utilize access and mobility management function (AMF) location service","description":"A method for mitigating location tracking and DoS attacks that utilize an AMF location service includes receiving, at an NF, an authentication response message from an HPLMN of a UE.
