Section: 5.2.3.3.2 Nudm_SDM_Get service operation
Content: Service Operation name: Nudm_SDM_Get Description: Consumer NF gets the subscription data indicated by the subscription data type input from UDM. The UDM shall check the requested consumer is authorized to get the specific subscription data requested. In the case of NF consumer is SMF, the subscriber data may contain e.g. Allowed PDU Session Type(s), Allowed SSC mode(s), default 5QI/ARP, Subscribed S-NSSAI(s). Inputs, Required: NF ID, Subscription data type(s), Key for each Subscription data type(s). Inputs, Optional: Data Sub Key(s), SoR Update Indicator, AF Identifier (for AF authorisation by the UDM), Disaster Roaming Indicator indicating that Disaster Roaming service is applied, Serving PLMN ID. NOTE: Some subscription data subsets can be specific to the Serving PLMN where the UE is registered (e.g. access and mobility subscription data) as defined in clause 5.2.12.2.1. If the corresponding NF consumer does not include the Serving PLMN ID, the UDM provides the subscription data for the SUPI associated to the HPLMN. If the AMF already has subscription data for the UE but the SoR Update Indicator in the UE context requires the AMF to retrieve SoR information depending on the NAS Registration Type ("Initial Registration" or "Emergency Registration"), the AMF shall include SoR update indicator in the Nudm_SDM_Get depending on the NAS Registration type. Outputs, Required: The consumer NF gets the requested subscription data. Outputs, Optional: None.
