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

Although FIG. 1 illustrates a case where a PDN and a DN are the same as each other, the PDN and the DN may be different from each other. The PDN may be a data network (DN) for providing a communication service to a UE. The DN may be configured as a packet data service network or configured for each service. The PDN may include a connected communication terminal. Therefore, connection to the PDN may be connection to a communication terminal or a server apparatus deployed in the PDN. The transmission and/or reception of user data to and/or from the PDN may be the transmission and/or reception of the user data to and/or from the communication terminal or the server apparatus deployed in the PDN. The PDN may be expressed as a DN, or the DN may be expressed as a PDN.

At least some of an access network_A, a core network_A, a PDN, an access network_B, a core network_B, and a DN, and/or one or more apparatuses included in the networks may be referred to as a network or a network apparatus. The transmission and/or reception of a message and the execution of a procedure by the network and/or the network apparatus mean the transmission and/or reception of the message and/or the execution of the procedure by at least some of the access network_A, the core network_A, the PDN, the access network_B, the core network_B, and the DN, and/or one or more apparatuses included in the networks.

The UE can be connected to the access network. Additionally, the UE can be connected to the core network via the access network. The UE can be connected to the PDN or the DN via the access network and the core network. The UE can transmit and/or receive (communicate) user data to and/or from the PDN or the DN. In a case that the user data is transmitted and/or received, not only internet protocol (IP) communication but also non-IP communication may be used.
