The private identifier may be used by a user equipment (UE) to access the private RAN. The method may include deploying network functions to one or more devices of a private network platform. The network functions may be associated with one or more radio access technologies (RATs). The method may include configuring the private network platform to host the network functions to provide a private multi-access edge computing (MEC) environment. The private MEC environment may be configured to host one or more MEC applications. The method may include configuring a communication interface between the private RAN and the private MEC environment to enable the UE to access, via the private RAN, the private MEC environment and performing an action associated with the private MEC environment. | 2020-07-23 |
