Abstract: An SDN controller configures a network element as a service edge. The SDN controller configures a service flow associated with a service to receive a required service treatment. The SDN controller configures an entry point to add routing tags on a set of packets associated with the service. The set of packets are routed in accordance with the routing tags. The required service treatment is applied at the service edge and the tags are removed from the set of packets, which are then forwarded to the network.

Abstract: Concepts and technologies disclosed herein are directed to an enhanced software-defined networking (“SDN”) controller to support ad-hoc radio access technologies (“RATs”). An SDN controller receives, from an ad-hoc radio access controller serving an ad-hoc radio access network (“RAN”), an attach request sent on behalf of a user equipment (“UE”) operating in communication with an ad-hoc RAT transceiver node. The attach request includes a physical IP address associated with the UE. The physical IP address includes an IP address sub-interface pre-fix broadcast to the UE by the ad-hoc RAT transceiver node combined with a physical address of the UE. In response to the attach request, the SDN controller can complete an attachment procedure for allowing the ad-hoc radio access controller to an SDN network. The SDN controller also can update one or more components operating within the SDN network to reflect how to reach the UE via the physical IP address.

Abstract: Concepts and technologies disclosed herein are directed to application-based multiple radio access technologies (“RAT”) and platform control using software-defined networking (“SDN”). According to one aspect of the concepts and technologies disclosed herein, an SDN controller can configure a radio access network (“RAN”) for connectionless services and for connection-oriented services. The RAN can support multiple RATs each capable of providing radio access to a device, such as a UE or an IoT device. The SDN controller can determine a user plane path configuration for an application flow through at least part of the RAN. The SDN controller can provide the user plane configuration to an SDN agent that is stored on and is executable by the device.

Abstract: A system that incorporates the subject disclosure may include, for example, facilitating establishing a first interface between a processor and the system where the system performs a policy and charging rules function in a mobile communications network and where the first interface bypasses a packet data network gateway and a serving gateway, facilitating establishing a second interface between the processor and the system where the second interface utilizes the packet data network gateway and the serving gateway, providing a first message from the processor to the system via the first interface where the first message is associated with a quality of service authorization, and receiving a second message from the system via the first interface where the second message is associated with the quality of service authorization. Other embodiments are disclosed.

Abstract: Facilitating device contexts, operational modes, and policy driven enhancements for paging in advanced networks (e.g., 4G, 5G, 6G, and beyond) is provided herein. Operations of a network device can comprise analyzing a group of contextual data for a user equipment device, and mobility management behaviors historically implemented for the user equipment device and based on an indication that a page request is scheduled to be sent to the user equipment device. The operations can also comprise configuring a paging message for the user equipment device based on the contextual data and the mobility management behaviors. Further, the operations can comprise sending the paging message to the user equipment device.

Abstract: Concepts and technologies are disclosed herein for creating and using native virtual probes in computing environments. A request for a service that includes a virtual function can be received, where the virtual function is to be monitored by a native virtual probe. An image of the service can be obtained, where the image can include a first image component for the virtual function and a second image component for the native virtual probe. The image can be deployed. Deployment of the image can result in instantiation of the virtual function on a computing device and instantiation of the native virtual probe on the computing device.

Abstract: Connecting user equipment (UE) to an application can be managed based on UE movement and location. During data session between UE and application, a communication management component (CMC) associated with anchor network component (ANC) or serving network component (SNC) determines UE location, and connects UE to the ANC and SNC, which enables access of the application via a data network associated with ANC. As UE moves, CMC tracks UE movement and communication conditions. If, when UE is at second location, a communication condition breaches threshold level, CMC determines whether interruption of the data session is permitted. If not, CMC determines whether there is a local SNC in proximity to second location. If there is, CMC can switch UE from SNC to local SNC, which can access local application content via local data network associated with application. If interruption permitted, UE deactivates and reactivates to connect to local ANC.

Abstract: The described technology is generally directed towards a frequency-aware cellular communication network. A mobile device, or a radio access network (RAN) device at a base station in communication with the mobile device, can proactively notify a core network device regarding changes of a frequency band used for communications between the mobile device and the base station. The core network can use received notifications to adjust service provided to the mobile device.
