NETWORK INITIATED PRIMARY AUTHENTICATION

Abstract: various aspects of the present disclosure relate to an authentication server function (ausf) that receives an authentication request from a security anchor function (seaf), and transmits a data request for authentication data to unified data management (udm). the ausf can receive the authentication data from the udm for primary authentication, and set an expiration time for security information associated with the primary authentication being successful. the ausf can then transmit an authentication message of authentication information that includes the security information and the expiration time to an authentication and key management for applications (akma) anchor function (aanf) that registers the expiration time. the ausf can also initiate reauthentication based at least in part on expiry of the authentication information.
