Techniques for subscription-based authentication in wireless communications

An apparatus for wireless communication, comprising:

• a transceiver;
• a memory;
• and
• at least one processor communicatively coupled with the transceiver and the memory, wherein the at least one processor is configured to:
• determine to access a discovered network for wireless communications;
• determine, based on a service provider associated with the discovered network, to use a modified universal subscriber identity module (USIM) subscription stored in the UE for authentication with the discovered network, wherein the modified USIM subscription is associated with multiple service provider identifiers that includes at least one of a domain-based service provider identifier based on a domain name or an operator identifier-based service provider identifier based on an operator identifier;
• generate a subscriber identifier for authenticating on the discovered network, wherein the subscriber identifier is generated based at least in part on a service provider identifier associated with the modified USIM subscription for the service provider and a modified mobile subscriber identity associated with the modified USIM subscription;
• and
• send the subscriber identifier to a node of the discovered network for the authentication.

A method for authenticating a user equipment (UE) in wireless communications, comprising:

• broadcasting information including a service provider identifier of a service provider associated with a network;
• receiving, from the UE, a subscriber identifier for authenticating the UE to access the network, wherein the subscriber identifier is generated based at least in part on the service provider identifier associated with the service provider and a modified mobile subscriber identity associated with the service provider, and wherein the service provider identifier is not a PLMN-ID;
• and
• authenticating the UE with the network based on a modification of a derivative of extensible authentication protocol (EAP) authentication and key agreement (AKA) (EAP-AKA′), wherein the modification comprises of communicating the subscriber identifier with the service provider for authentication.
