NIDD service may be used to handle Mobile Originated (MO) and Mobile Terminated (MT) communication with UEs to AF, where the data used for the communication is considered unstructured (a.k.a., Non-IP).

NIDD is handled using an Unstructured PDU session to the NEF, and NIDD API may be used for a PDU session based on the configuration in the subscription.

The NIDD configuration service can be used for AF to update the NEF ID for the NIDD service, and to indicate which serialization formats it supports for mobile originated and mobile terminated traffic in the Reliable Data Server Configuration.

Therefore, for evaluation of NIDD performance, the NIDD configuration and NIDD service need to be monitored with the relevant performance measurements.
