1. An evolved Node B (“

  • eNB”

    ) comprising;

    first circuitry to connect to a plurality of mobility management entities (“

    MMEs”

    ) and obtain communications from individual MMEs of the plurality of MMEs over corresponding S1 interfaces; and

    second circuitry, coupled with the first circuitry, to;

    determine, based on a first communication of the communications obtained over a first S1 interface of the S1 interfaces, a first MME of the plurality of MMEs that is dedicated to handle Machine-Type Communication (“

    MTC”

    ) network traffic associated with a first priority level, which is lower than a second priority level associated with other network traffic,determine, based on overload information in the first communication or in another first communication obtained over the first S1 interface, whether the first MME is overloaded, andselect the first MME for a user equipment (“

    UE”

    ) based on an indication that the UE is to generate MTC network traffic when the first MME is not overloaded according to the overload information, orselect a second MME of the plurality of MMEs for the UE when the first MME is overloaded according to the overload information regardless of whether the second MME is dedicated to handle network traffic associated with the first priority level.
