Abstract
A method for mitigating a 5G roaming attack for an Internet of things (IoT) device based on expected user equipment (UE) behavior patterns includes receiving, at a network function (NF) including at least one processor, a service request message requesting a service from a home public land mobile network (PLMN) of a UE identified in the service request message, wherein the UE comprises an IoT device and obtaining, for the UE identified in service request message, at least one parameter provisioned in the home PLMN to indicate an expected UE behavior pattern. The method further includes comparing the at least one parameter provisioned in the home PLMN to indicate the expected UE behavior pattern to at least one parameter from the service request message and that the at least one parameter from the service request message is not indicative of the expected UE behavior pattern of the UE. The method further includes dropping or rejecting the service request message.
