Small data transmission techniques in a wireless communication network
First Claim
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.

6. A method comprising:
-
receiving, by a node including a Mobility Management Entity (MME) or a Serving General Packet Radio Service Support Node (SGSN), a request to send a data payload to user equipment (UE) of a wireless communication network over a radio access network (RAN); sending, by the node to the UE via the RAN, a paging message including a small data indicator information element that indicates that a data payload intended for transmission to the UE is located at the node, and wherein the data payload is smaller than a preconfigured threshold; subsequent to sending the paging message, sending, by the node to the UE via the RAN, a non-access stratum (NAS) message that includes the data payload; and receiving, by the node from the UE, an extended service request message to request a NAS attachment with the node and to indicate whether the UE has a small data payload to send to the wireless communication network, wherein; the extended service request message is sent by the UE in response to the paging message and upon establishment of a Radio Resource Control (RRC) connection between the UE and the RAN; the extended service request message includes a service type information element having a service type value that is to indicate that a purpose of the NAS attachment with the node is for small data transmission and whether the UE has a small data payload to send to the wireless communication network; and the service type information element includes four bits to indicate the service type value. - View Dependent Claims (7, 8)

9. A base station, comprising:
-
one or more non-transitory computer-readable media having instructions; and one or more processors coupled with the one or more computer-readable media to execute the instructions to; receive, from a node of a wireless communication network including a Mobility Management Entity (MME) or a Serving General Packet Radio Service Support Node (SGSN), a first paging message including a small data indicator information element that indicates transmission of a data payload from the node to a user equipment (UE) of the wireless communication network, wherein the data payload is a small data payload that is smaller than a preconfigured threshold; and send a second paging message including the small data indicator information element to the UE, wherein; the first paging message received by the base station includes the small data payload; the second paging message sent by the base station does not include the small data payload; the small data indicator information element in the second paging message indicates that the small data payload is intended for transmission to the UE and is located at the base station; and the one or more processors are further to execute the instructions to receive a radio resource control (RRC) connection request message from the UE, the RRC connection request message being sent by the UE in response to the paging message, and receive, from the UE in response to the RRC connection request message, an RRC connection setup complete message and an extended service request message to request a NAS attachment with the node, wherein the extended service request message includes a service type information element having a service type value, and wherein the service type value indicates that a purpose of the NAS attachment with the node is for small data transmission and indicates whether the UE has a small data payload to send to the wireless communication network. - View Dependent Claims (10)
