5.2.18.2.1 Nucmf_Provisioning_Create service operation

Service operation name: Nucmf_Provisioning_Create

Description: The consumer creates a UCMF dictionary entry (or more entries) for a Manufacturer-assigned UE Radio Capability ID(s). For each UE Radio Capability ID the following inputs are provided:

a) a UE radio access capability set with respective coding format or the UE radio access capability set in both TS 36.331 [16] and TS 38.331 [12] coding formats and each RATs’ UE Radio Capability for Paging; and

b) the related UE model(s) IMEI/TAC value(s) the UE radio capability ID applies to.

Inputs, Required: (list of) [UE Radio Capability ID(s), set(s) of UE radio access capability set and UE Radio Capability for Paging and respective Coding format(s), (list of) IMEI/TAC value(s)].

Inputs, Optional: None.

Outputs, Required: None.

Outputs, Optional: None.

The Coding format(s) indicates the format of the respective UE radio access capabilities as defined in TS 36.331 [16] or TS 38.331 [12]. The UCMF dictionary entry shall not contain UTRAN radio capabilities.

5.2.18.2.2 Nucmf_Provisioning_Delete service operation

Service operation name: Nucmf_Provisioning_Delete

Description: The consumer deletes a UCMF dictionary entry(s) for a Manufacturer-assigned UE Radio Capability ID(s). The consumer provides a (list of) UE radio capability ID value(s) to be deleted or it may provide the IMEI/TAC values for which the associated UE radio capability ID entries shall be no longer used.

Inputs, Required: UE Radio Capability ID(s) of the UCMF dictionary entry(s) to be deleted or IMEI/TAC that no longer use associated UE radio Capability ID(s).

Inputs, Optional: None.

Outputs, Required: None.

Outputs, Optional: None.

5.2.18.2.3 Nucmf_Provisioning_Update service operation

Service operation name: Nucmf_Provisioning_Update

Description: The consumer updates the list of IMEI/TAC values a UCMF dictionary entry (or a list of entries) applies to for a Manufacturer-assigned UE Radio Capability ID. For each UE Radio Capability ID provided, (a list of) UE model(s) IMEI/TAC value(s) to be added or removed to the related UCMF entry is provided.

Inputs, Required: Update Type (one of "Add IMEI/TAC Values" or "Remove IMEI/TAC Values") and:

– If Update Type is "Add IMEI/TAC Values", the (list of) UE Radio Capability ID(s) of the UCMF dictionary entry(ies) to be updated and the related additional (list of) IMEI/TAC(s); or

– If Update Type is "Remove IMEI/TAC Values", the (list of) UE Radio Capability ID(s) of the UCMF dictionary entry(ies) to be updated and the related (list of) IMEI/TAC(s) to be removed.

Inputs, Optional: None.

Outputs, Required: None.

Outputs, Optional: None.

5.2.18.3 Nucmf_UECapabilityManagement Service

5.2.18.3.1 Nucmf_UECapabilityManagement Resolve service operation

Service Operation name: Nucmf_UECapabilityManagement_Resolve

Description: Consumer NF gets the UE Radio Access Capability and one or more UE Radio Capability for Paging corresponding to a specific UE Radio Capability ID (either Manufacturer-assigned or PLMN-assigned) and Coding Format.

Inputs, Required: UE Radio Capability ID, Coding format, one or more UE Radio Capability for Paging.

Inputs, Optional: None.

Outputs, Required: UE Radio Access Capability, UE Radio Capability for Paging.

Outputs, Optional: None.

The Coding format indicates the format as defined in TS 36.331 [16] or TS 38.331 [12] of the UE Radio Access Capability expected by the NF in output. When the Coding Format is TS 36.331 [16], the UCMF shall provide the UE Radio Capability for Paging for E-UTRA. When the Coding Format is TS 38.331 [12], the UCMF shall provide the UE Radio Capability for Paging for NR and, if the PLMN supports E-UTRA connected to 5GC, shall provide the UE Radio Capability for Paging for E-UTRA.

5.2.18.3.2 Nucmf_UECapabilityManagement_Assign service operation

Service or service operation name: Nucmf_UECapabilityManagement_Assign

Description: The NF consumer sends to the UCMF:

– the UE Radio Access Capability (and its Coding Format); or

– the UE Radio Access Capability and UE Radio Capability for Paging in both TS 36.331 [16] and TS 38.331 [12] coding formats;

and obtains a PLMN-assigned UE Radio Capability ID in return.

Inputs, Required: UE Radio Access Capability(s), UE Radio Capability for Paging(s), Coding format(s), IMEI/TAC.

Inputs, Optional: One or more UE Radio Capability for Paging.

Outputs, Required: UE Radio Capability ID.

Outputs, Optional: None.

The AMF does not send NB-IoT Radio Access Capability to the UCMF.

The Coding format indicates the format of the UE Radio Access Capability as defined in TS 36.331 [16] or TS 38.331 [12].

5.2.18.3.3 Nucmf_UECapabilityManagement_Subscribe service operation

Service operation name: Nucmf_UECapabilityManagement_Subscribe

Description: The NF consumer subscribes for updates to UCMF dictionary entries and provides the coding format in which UE Radio Access Capability is expected by NF. The UCMF shall check the requested consumer is authorized to subscribe to requested updates.

Inputs, Required: Coding format.

Inputs, Optional: None.

Outputs, Required: None.

Outputs, Optional: None.

The Coding format indicates the format of the UE Radio Access Capability as defined in TS 36.331 [16] or TS 38.331 [12].

5.2.18.3.4 Nucmf_UECapabilityManagement_Unsubscribe service operation

Service operation name: Nucmf_UECapabilityManagement_Unsubscribe

Description: The NF consumer unsubscribes from updates to UCMF dictionary entries.

Inputs, Required: None.

Inputs, Optional: None.

Outputs, Required: None.

Outputs, Optional: None.

5.2.18.3.5 Nucmf_UECapabilityManagement_Notify service operation

Service Operation name: Nucmf_UECapabilityManagement_Notify
