1. An apparatus comprising:

  • non-access stratum (NAS) circuitry coupled with access stratum (AS) circuitry, the NAS circuitry to;

    receive a trigger to send a data payload to a wireless communication network, the data payload having a size that is less than a preconfigured threshold;

    generate a NAS message including the data payload; and

    transmit, using the AS circuitry, the NAS message including the data payload to a node comprising a Mobility Management Entity (MME) or a Serving General Packet Radio Service Support Node (SGSN) upon establishment of a Radio Resource Control (RRC) connection,wherein the NAS message is an attach request message for initiation of an attachment procedure with the node and the attach request message includes a communication type information element, and the communication type information element is an attach type information element that includes three bits to indicate an attach type value, wherein the attach type value is to indicate that a purpose of the attachment procedure with the node is for small data transmission.
