Systems and methods for null-scheme access authorization

A network device comprising:

• at least one processor,
• wherein the at least one processor is configured to:
• receive a registration request that comprises a subscription concealed identifier (SUCI) associated with a user equipment (UE) device;
• determine whether the SUCI indicates a request for null-scheme network access;
• retrieve, from at least one of a user data repository (UDR) device or a subscriber location function (SLF) device, a scheme authorization parameter for the UE device when it is determined that the SUCI indicates a request for null-scheme network access,
• wherein the scheme authorization parameter indicates whether the UE device is authorized for null-scheme access to a service provider network;
• determine whether the UE device is authorized for null-scheme network access based on the retrieved scheme authorization parameter;
• and
• perform processing associated with null-scheme network access when it is determined that the UE device is authorized for null-scheme network access.

A non-transitory computer-readable medium having stored thereon sequences of instructions which, when executed by at least one processor, cause the at least one processor to:

• receive, at a network device, a registration request that comprises a subscription concealed identifier (SUCI) associated with a user equipment (UE) device;
• determine, by the network device, whether the SUCI indicates a request for null-scheme network access;
• retrieve, by the network device and from at least one of a user data repository (UDR) device or a subscriber location function (SLF) device, a scheme authorization parameter for the UE device when it is determined that the SUCI indicates a request for null-scheme network access,
• wherein the scheme authorization parameter indicates whether the UE device is authorized for null-scheme access to a service provider network;
• determine, by the network device, whether the UE device is authorized for null-scheme network access based on the retrieved scheme authorization parameter;
• and
• perform, by the network device, processing associated with null-scheme network access when it is determined that the UE device is authorized for null-scheme network access.
