1. A method comprising:
through connection of a user equipment (UE) to a public wireless wide area (WWA) access network operated by a mobile network operator, performing, by the UE, a secondary authentication process involving an authentication node of an enterprise network that is to generate authentication material for the UE;
obtaining, by the UE, upon successful completion of the secondary authentication process, an identifier of the authentication node and an identifier of the UE provided by the authentication node;
obtaining, by the UE, a broadcast from a private WWA access network associated with the enterprise network, the broadcast indicating fast roaming support by the private WWA access network;
transmitting a request to register with the enterprise network, wherein the request comprises the identifier of the authentication node and the identifier of the UE provided by the authentication node, wherein the identifier of the authentication node is to enable a mobility management node of the enterprise network to identify the authentication node and the identifier of the UE is to enable the authentication node to identify the authentication material for the UE; and
establishing a connection with the enterprise network via the private WWA access network based on the authentication material.
