Small data transmission techniques in a wireless communication network

摘要

Embodiments of the present disclosure describe techniques and configurations for transmitting small data payloads in a wireless communication network. An apparatus may include non-access stratum (NAS) circuitry configured 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, and generate a NAS message including the data payload and access stratum (AS) circuitry coupled with the NAS circuitry and configured to transmit the NAS message including the data payload to a node comprising a Mobility Management Entity (MME) or a Serving GPRS (General Packet Radio Service) Support Node (SGSN). Other embodiments may be described and/or claimed.

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; andtransmit, 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.
