Network slice-specific authentication and authorization

An apparatus for wireless communication, comprising:

• a processor,
• memory coupled with the processor, the processor and memory configured to:
• determine, prior to a registration procedure associated with a network slice, an authentication credential associated with network slice information;
• transmit, to an access and mobility management function and prior to the registration procedure associated with the network slice, a first indication related to an availability of the authentication credential associated with the network slice information;
• and
• access, in response to network slice-specific authentication and authorization of the network slice information, the network slice associated with the network slice information based at least in part on the transmitted first indication related to the availability of the authentication credential associated with the network slice information.

An apparatus for wireless communication, comprising:

• a processor,
• memory coupled with the processor, the processor and memory configured to:
• receive, from a user equipment (UE), a first indication related to an availability of an authentication credential associated with network slice information;
• determine, based at least in part on the first indication, that the network slice information is subject to network slice-specific authentication and authorization;
• and
• provision the authentication credential associated with the network slice information for the UE based at least in part on the determining.

An apparatus for wireless communication, comprising:

• a processor,
• memory coupled with the processor, the processor and memory configured to:
• determine, at a user data management function, a subscription to network slice information by a user equipment (UE);
• determine, at the user data management function, that the network slice information is subject to network slice-specific authentication and authorization;
• and
• transmit, from the user data management function to an access and mobility management function, an indication related to an authentication credential associated with the network slice information, the indication indicating that the authentication credential associated with the network slice information is unavailable at the UE.
