  • Methods, systems, and computer readable media for preventing subscriber identifier leakage
    Patent number: 11558737
    Abstract: A method for preventing subscriber identifier leakage from a telecommunications network includes receiving, by a security edge protection proxy (SEPP), an authentication response message authorizing a subscriber in a visitor network, wherein the authentication response message includes a home subscriber identifier used to identify the subscriber within a home network. The method further includes replacing, by the SEPP, the home subscriber identifier in the authentication response message with a visitor subscriber identifier. The method further includes forwarding, by the SEPP, the authentication response message with the visitor subscriber identifier to a visitor network.

  • 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
    Patent number: 11516671
    Abstract: 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. 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.
