1. Machine-type communication (“

  • MTC”

    ) user equipment (“

    UE”

    ) comprising;

    one or more processors;

    memory coupled with the one or more processors; and

    at least one module, loaded into the memory and operated by the one or more processors, to;

    detect a plurality of wireless cells, each provided by an evolved Node B (“

    eNB”

    );

    detect eNB categories associated with individual wireless cells of the plurality of wireless cells;

    identify one or more wireless cells of the plurality of detected wireless cells on which MTC traffic is permitted based on the associated eNB categories;

    cross check a list of MTC-dedicated eNBs to which the MTC UE is permitted to connect against the identified wireless cells;

    determine that none of the MTC-dedicated eNBs on the list are able to serve the MTC UE;

    identify an eNB that serves both MTC and non-MTC traffic, based on an MTC policy of the eNB that identifies a circumstance under which the eNB will permit MTC traffic;

    selectively join a wireless cell provided by the eNB that serves both MTC and non-MTC traffic based on the identification of the eNB that serves both MTC and non-MTC traffic; and

    transition the MTC UE from a connected mode to an idle mode, and while in idle mode;

    periodically detect another plurality of wireless cells, each provided by an eNB;

    detect eNB categories associated with individual wireless cells of the another plurality of wireless cells;

    identify one or more wireless cells of the another plurality of detected wireless cells on which MTC traffic is permitted based on the associate eNB categories; and

    selectively initiate handoff from the wireless cell to which the MTC UE previously selectively joined to another wireless cell of the one or more identified wireless cells of the another plurality of detected wireless cells based on a cell selection criterion.
