Equipment Identity Register Services

5G-EIR5G-Equipment Identity Register
EIREquipment Identity Register
PEIPermanent Equipment Identifier

N5G-eir is a Service-based interface , to Check the status of Equipment's identity, which is an optional network function

Services offered by the 5G-EIR NF

N5g-eir_EquipmentIdentityCheck Service

Service Description

The N5g-eir_Equipment Identity Check service is provided by the 5G-EIR to check the Permanent Equipment Identifier (PEI) whether it is in the black list or not. The service can be consumed by AMF which initiates ME identity check by invoking the N5g-eirEquipmentIdentityCheckGet service operation.

The NF Service Consumer (e.g. AMF) sends a GET request to the resource representing the PEI equipment Status. It shall include the PEI as a query parameter and, optionally, the SUPI may also be included.

On success, "200 OK" with the message body containing the equipment status of the PEI.

If the PEI is not known, "404 Not Found" with the message body containing a ProblemDetails object, with the "details" attribute set to "ERROR_EQUIPMENT_UNKNOWN".

When receiving the response from the 5G-EIR, the NF Service Consumer (e.g. AMF) shall check the equipment Status and the detailed problem. Dependent upon the result, the NF Service Consume will decide its subsequent actions (e.g. sending a Registration Reject if the 5G-EIR indicates that the PEI is unknown or blacklisted).

Error Handling

The common application errors defined in the Table in 3GPP TS 29.500 [4] may also be used for the N5g-eir_EquipmentIdentityCheck service, and the following application errors listed in the below Table are specific for the N5g-eir_EquipmentIdentityCheck service.
