In coordination with the MVNO, the enterprise or enterprise server 528 may request and/or participate in the creation of the private network slice for the enterprise in the 5G network of the MNVO (step 608 of FIG. 6A). The private network slice may be associated with a NSI identifier (NSI ID), which may be returned to the enterprise server 528 along with other relevant information (step 610 of FIG. 6A). The enterprise or enterprise server 528 may create credentials, such as a Client ID and Secret (e.g. OAuth 2.0), and associate them with the identity of the private network slice (e.g. the NSI ID) (step 612 of FIG. 6A). The credentials may also be associated with selected, desired enterprise “scopes.” The credentials may be shared with UE 102 or its enterprise application (step 614 of FIG. 6A). The credentials, as well as claims to assist in making an authorization decision, may be shared with the MNVO (step 616 of FIG. 6A).

Referring now to FIG. 6B, according to some implementations, enterprise server 528 may request and/or participate in creation of the private network slice for the enterprise according to the process flow diagram 600B. In the present example, NEF 136 may provide an API for enterprise server 528 to request creation of the private network slice for the enterprise. In this implementation, NEF 136 may be configured to operate as a network slice controller, and/or even a communications service management function (CSMF).
