## Abstract

An object is to provide a network apparatus capable of performing a communication procedure suitable for accommodating an IoT device. A network apparatus (10) according to present disclosure includes a communication unit (11) configured to receive profile information of a communication terminal (20) transmitted from the communication terminal (20), and a determination unit (12) configured to determine, in a procedure for establishing a radio link between the network apparatus (10) and the communication terminal (20), whether or not to skip at least one of a procedure for configuring a radio resource used for communication of user data between the network apparatus (10) and the communication terminal (20) and a procedure for setting security between the network apparatus (10) and the communication terminal (20) according to the profile information, in which the communication unit (11) receives small data transmitted from the communication terminal (20) through the radio link.

## Claims

### Claim 1

A User Equipment (UE) comprising:
a processor; and a memory having stored thereon a set of instructions executable by the processor, wherein upon execution of the instructions the processor causes the UE to:
send, to a mobility management node, a registration request message including first capability information indicating that the UE supports Cellular Internet of Things (CIoT) data transfer using a Control plane (C-plane);
receive, from the mobility management node, a registration accept message including second capability information indicating that the mobility management node supports the CIoT data transfer using the C-plane; and
after completion of a registration procedure, send, to a base station, a Radio Resource Control (RRC) connection setup complete message including a Non-Access Stratum (NAS) message carrying data and further including third capability information indicating that the UE supports CIoT data transfer using the C-plane.

### Claim 2 (depends on 1)

The UE according to claim 1, wherein the base station sends, to the mobility management node, an Initial UE message including the data.

### Claim 3

A method of a User Equipment (UE) comprising:
sending, to a mobility management node, a registration request message including first capability information indicating that the UE supports Cellular Internet of Things (CIoT) data transfer using a Control plane (C-plane);
receiving from the mobility management node, a registration accept message including second capability information indicating that the mobility management node supports the CIoT data transfer using the C-plane; and
after completion of a registration procedure, sending, to a base station, a Radio Resource Control (RRC) connection setup complete message including a Non-Access Stratum (NAS) message carrying data and further including third capability information indicating that the UE supports the CIoT data transfer using the C-plane.

### Claim 4 (depends on 3)

The method according to claim 3, wherein the base station sends, to the mobility management node, an Initial UE message including the data.

### Claim 5

A mobility management node comprising:
a processor; and
a memory having stored thereon a set of instructions executable by the processor, wherein upon execution of the instructions the processor causes the mobility management node to:
receive, from a User Equipment (UE), a registration request message including first capability information indicating that the UC supports Cellular Internet of Things (CIoT) data transfer using a Control plane (C-plane);
send, to the UE, a registration accept message including second capability information indicating that the mobility management node can support the CIoT data transfer using the C-plane; and
after completion of a registration procedure, receive, from a base station, an Initial UE message including data wherein the base station receives, from the UE, a Radio Resource Control (RRC) connection setup complete message including a Non-Access Stratum (NAS) message carrying the data and further including the third capability information indicating that the UE supports the CIoT data transfer using the C-plane.

### Claim 6

A method of a mobility management node comprising:
receiving, from a UE (User Equipment), a registration request message including first capability information indicating that the UE supports Cellular Internet of Things (CIoT) data transfer using a Control Plane (C-plane);
sending, to the UE, a registration accept message including second capability information indicating that the mobility management node supports the CIoT data transfer using the C-plane; and
after completion of a registration procedure, receiving, from a base station, an Initial UE message including data wherein the base station receives, from the UE, a Radio Resource Control (RRC) connection setup complete message including a Non-Access Stratum (NAS) message carrying the data and further including third capability information indicating that the UE supports the CIoT data transfer using the C-plane.
