Abstract
A method for detecting and mitigating effects of abnormal MTC device behavior includes, at a telecommunications network node comprising one of an MME, DRA, or SCEF, receiving CP information from which core network (CN) assistance information for tuning an evolved node B (eNB) to minimize MTC device state transitions is derivable, forwarding the CP information or CN assistance information derived from the CP information to another network node, deriving, from the CP information, a rule for policing behavior of the MTC device, storing the rule in memory of the telecommunications network node, monitoring uplink communications from the MTC device, determining, using the stored rule derived from the CP information, that the MTC device is not behaving in accordance with an expected behavior; and, in response performing a network security action that mitigates an effect of traffic from the MTC device on the network.
