Abstract
In a telecommunication network, a Serving Call Session Control Function (S-CSCF) may be coupled with a Fifth Generation (5G) Equipment Identity Register (EIR) via an N17' interface. In some examples, the S-CSCF can use the N17′ interface instead of a diameter protocol for communicating with the 5G-EIR. The S-CSCF can send a request to the 5G-EIR including a Permanent Equipment Identifier (PEI) associated with a user equipment (UE). In response, the S-CSCF can receive identity data indicative of whether the UE is authorized, not authorized, partially authorized, or unknown. Based on the identity data, the S-CSCF can authenticate a user equipment (UE) accessing a network. In some examples, the S-CSCF may route requests between a 5G-EIR and an EIR. In some examples, this authentication step can comprise a second-level authentication to identify stolen or fraudulent devices and to prevent such devices from accessing the network.
