Second identification information is information indicating whether or not the UE supports control plane CIoT 5GS optimization. The second identification information may be a CP CIoT bit (Control plane CIoT 5GS optimization). The CP CIoT bit may indicate that control plane CIoT 5GS optimization is supported (control plane CIoT 5GS optimization supported). The CP CIoT bit may indicate UE capability in 5G and include a 5GMM capability information element.
The second identification information may be information selected and determined based on the configuration of the UE, the state of the UE, a user policy, and/or a request for an application.
Third identification information is information indicating whether or not the UE supports user plane CIoT 5GS optimization. The third identification information may be an UP CIoT bit (User plane CIoT 5GS optimization). The UP CIoT bit may indicate that user plane CIoT 5GS optimization is supported (user plane CIoT 5GS optimization supported). The UP CIoT bit may indicate UE capability in 5G and include a 5GMM capability information element.
The third identification information may be information selected and determined based on the configuration of the UE, the state of the UE, a user policy, and/or a request for an application.
