Abstract: Disclosed are systems and methods for an advanced authorization framework that provides advanced network security and control of network hosted data. The disclosed framework provides computerized mechanisms that dictate a control of which data is accessible by particular network components, and which operations the privileged components are enabled to be performed. The disclosed framework can allow Network Function (NF) service consumers to discover and request network data that is specific to the operational status (e.g., PCF can request policy data). The disclosed framework provides an access scope of the NF service consumer that manages which hosted data is accessible, and to what degree it can be manipulated, if at all.

Abstract: A device receives a call invitation message with a Session Description Protocol (SDP) offer for establishing a call between a calling party and a called party and obtains a set of network fallback rules associated with the called party. The device determines, based on the set of network fallback rules, whether to reject the call and avoid network fallback from a first wireless network to a second wireless network. The device sends, based on the determination, a call denial message without an SDP answer, to reject the call and avoid the network fallback.

Abstract: A device of a network may receive a session configuration message for an application session associated with an application of a user equipment (UE) that provided the session configuration message. The device of a network may identify, from the session configuration message, a quality of service (QoS) profile for the application session. The device of a network may determine that the application is authorized to use a network slice of the network that satisfies one or more QoS thresholds of the QoS profile. The device of a network may identify resources of the network that can be configured to satisfy the one or more QoS thresholds. The device of a network may instantiate the resources for communication of application data of the application session. Instantiating the resources may enable the UE to communicate the application data via the network slice using the resources.
