Abstract
Providing 5G-AKA User Equipment (UE) authentication and, more specifically, providing 5G-AKA UE authentication at an edge of a network may be provided. An Authentication Server Function (AUSF) at an edge of a network, and the AUSF may request an Authentication Vector (AV) from a Unified Data Management (UDM). The AUSF may receive AV from the UDM and cache the AV at an AV cache. An authentication request may be received from an Access and Mobility Management Function (AMF) and the AV from the AV cache may be provided to the AMF.
Claims15
A method comprising:
- executing an Authentication Server Function (AUSF) at an edge of a network;
- requesting, by the AUSF, an Authentication Vector (AV) from a Unified Data Management (UDM);
- receiving the AV from the UDM;
- caching the AV at an AV cache;
- receiving an authentication request from an Access and Mobility Management Function (AMF);
- providing the AV from the AV cache to the AMF;
- and
- determining the UDM is inaccessible, wherein providing the AV from the AV cache to the AMF is in response to determining the UDM is inaccessible.
A system comprising:
- a memory storage;
- and
- a processing unit coupled to the memory storage, wherein the processing unit is operative to:
- executing an Authentication Server Function (AUSF) at an edge of a network;
- cause the AUSF to request an Authentication Vector (AV) from a Unified Data Management (UDM);
- receive the AV from the UDM;
- cache the AV at an AV cache;
- receive an authentication request from an Access and Mobility Management Function (AMF);
- provide the AV from the AV cache to the AMF;
- receive an authentication confirmation from the AMF;
- send the authentication confirmation to the UDM;
- receive a confirmation of authentication confirmation success from the UDM;
- send the authentication confirmation to an authentication confirmation and result removal queue;
- and
- receive the authentication confirmation from the authentication confirmation and result removal queue, wherein to send the authentication confirmation to the UDM is in response to receiving the authentication confirmation from the authentication confirmation and result removal queue.
A computer-readable medium that stores a set of instructions which when executed perform a method executed by the set of instructions comprising:
- executing an Authentication Server Function (AUSF) at an edge of a network;
- requesting, by the AUSF, an Authentication Vector (AV) from a Unified Data Management (UDM);
- receiving the AV from the UDM;
- caching the AV at an AV cache;
- receiving an authentication request from an Access and Mobility Management Function (AMF);
- providing the AV from the AV cache to the AMF;
- requesting, by the AUSF, a second AV from the UDM;
- receiving the second AV from the UDM;
- caching the second AV at the AV cache;
- and
- receiving an AV request from an AV request queue, wherein requesting the second AV from the UDM is in response to receiving the AV request.
