摘要

Provided is a communication unit configured to allow a function for CIoT to be used even in a 5GS that supports a network-initiated configuration update procedure and a plurality of types of session and service continuities. Further provided is a communication unit configured to appropriately manage, by a user equipment, connection established between the user equipment and a network even in a case that a network-initiated change of a state of the user equipment has been performed. Thereby, the communication unit for implementing the function for CIoT in the 5GS and the communication unit for implementing a network-initiated procedure of changing the state of the user equipment are provided.

說明書

The UE can designate a PDU session type indicating the type of PDU session requested to be established. As disclosed previously, any one of IPv4, IPv6, IP, Ethernet, and Unstructured can be designated as the PDU session type. The UE can include an SSC mode of the PDU session requested to be established in the PDU session establishment request message.

In a case where the UE supports the control plane CIoT 5GS optimization and/or the header compression for control plane CIoT 5GS optimization, the UE may include configuration information of a header compression function (header compression configuration IE) in the PDU session establishment request message. In more detail, in a case where the PDU session type is any one of IPv4, IPv6, and IP and the UE supports the control plane CIoT 5GS optimization and/or the header compression for control plane CIoT 5GS optimization, the UE may include the configuration information of the header compression function in the PDU session establishment request message.

In a case where the PDU session type is set to be any one of IPv4, IPv6, and IP, and the support of the control plane CIoT 5GS optimization and/or the header compression for control plane CIoT 5GS optimization is indicated by a registration request message, the UE may further include the configuration information of the header compression function in the PDU session establishment request message.
