Techniques to facilitate fast roaming between a mobile network operator public wireless wide area access network and an enterprise private wireless wide area access network

One or more non-transitory computer readable storage media encoded with instructions that, when executed by a processor, cause the processor to perform operations, comprising:

• generating, by an authentication node of an enterprise network operated by an enterprise entity, authentication material for a user equipment (UE) based on the UE being connected to a public cellular access network, wherein the public cellular access network operated by a mobile network operator and the UE is associated with the enterprise entity and wherein the generating is performed through a secondary authentication process for the UE performed via the authentication node of the enterprise network in which the secondary authentication process is initiated during a session establishment of the UE with a user plane function of a mobile network operated by the mobile network operator following a primary authentication process for the UE performed via connection of the UE for the public cellular access network operated by the mobile network operator;
• obtaining, by the authentication node of the enterprise network, an indication that the UE is attempting to access a private cellular access network operated by the enterprise entity, wherein in attempting to access the private cellular access network, the UE is to provide an identifier of the authentication node of the enterprise network and an identifier for the UE, wherein the identifier of the authentication node and the identifier of the UE facilitates identifying the authentication material for the UE via the authentication node;
• and
• providing, by the authentication node of the enterprise network, the authentication material for the UE to a mobility management node of the enterprise network, wherein the authentication material facilitates connection establishment between the UE and the private-cellular access network.

A system comprising:

• at least one memory element for storing data;
• and
• at least one processor for executing instructions associated with the data, wherein executing the instructions causes the system to perform operations, comprising:
• generating, by an authentication node of an enterprise network operated by an enterprise entity, authentication material for a user equipment (UE) based on the UE being connected to a public cellular access network, wherein the public cellular access network is operated by a mobile network operator and the UE is associated with the enterprise entity and wherein the generating is performed through a secondary authentication process for the UE performed via the authentication node of the enterprise network in which the secondary authentication process is initiated during a session establishment of the UE with a user plane function of a mobile network operated by the mobile network operator following a primary authentication process for the UE performed via connection of the UE for the public cellular access network operated by the mobile network operator;
• obtaining, by the authentication node of the enterprise network, an indication that the UE is attempting to access a private cellular access network operated by the enterprise entity, wherein in attempting to access the private cellular access network, the UE is to provide an identifier of the authentication node of the enterprise network and an identifier for the UE, wherein the identifier of the authentication node and the identifier of the UE facilitates identifying the authentication material for the UE via the authentication node;
• and
• providing, by the authentication node of the enterprise network, the authentication material for the UE to a mobility management node of the enterprise network, wherein the authentication material facilitates connection establishment between the UE and the private cellular access network.
