A device can receive, at a radio access network (RAN) and from a user device, first information to initiate a communications session that has one or more properties. The device can send second information to an access and mobility management function component (AMF) to authenticate the user device. The device can send third information to a user plane function component (UPF) to determine a set of network slice policies for managing the communications session. The device can receive the set of network slice policies and apply the set of network slice policies to the communications session. The device can detect a change in the one or more properties of the communications session and send a signal to the UPF to analyze the communications session. The device can receive a new set of network slice policies and apply the new set of network slice policies to the communications session.
