Systems and methods relating to a core network detection mechanism for detecting abnormal signaling patterns for signaling aimed at wireless devices (e.g., low-power consumption wireless devices such as low-power consumption Machine Type Communication (MTC) devices) are disclosed. In some embodiments, a method of operation of a core network node in a cellular communications network comprises receiving signaling aimed at a wireless device, detecting, via a detection mechanism, an abnormal signaling pattern based on the signaling, and taking one or more actions upon detecting an abnormal signaling pattern. In this manner, an action(s) may be made to mitigate increased power consumption at the wireless device due to abnormal signaling.
