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: Node identifiers can be assigned to packet core policy nodes and directly routed to a diameter routing agent (DRA) and application functions (AFs) within a call processing message that is employed to establish an application service. Such a policy node identity will be received by Application Functions, UEs and/or intermediate message routers during the initial establishment of a packet data session so that they can refer to the policy node entity directly in the sub-sequent call processing flows related the established session, instead of querying a relational database which can be complex to maintain with multi-million correlation records. As an example, the policy node identifiers can be configurable and can comprise a hostname of the policy nodes, address data associated with the policy nodes, or a defined numerical value that maps to the hostname of the policy nodes.

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: Network and/or application resources can be dynamically instantiated based on service attributes and/or network capabilities. In one aspect, a customized and/or localized core slice can be selected that can deliver the requested service with target performance parameters. According to an aspect, dynamic selection, control, and/or management reporting can be provided for core network slices. Moreover, optimal core network slice selection can be performed to reduce network transport costs and efficiently deliver various services using an optimal core slice that matches a service profile being requested by an end user and/or device.

Abstract: Tracking areas that comprise service cells capable of providing advanced long-term evolution (LTE-A) features, can be utilized to indicate to a mobile device that the mobile device can access the advanced features. For example, an LTE-A capable mobile device can display an LTE-A icon if the mobile device is in a geographic area that qualifies as an LTE-A tracking area. However, if the mobile device is not capable of receiving LTE-A services, then the mobile device can display an LTE icon instead of an LTE-A icon.

Abstract: A method includes receiving, at a server connected to a network, a plurality of emergency alerts from a plurality of devices connected to the network. The method also includes analyzing, by the server, the plurality of emergency alerts to determine an emergency type of each of the plurality of emergency alerts. The method includes categorizing, by the server, the plurality of emergency alerts based on the emergency type of each of the plurality of emergency alerts. The method includes prioritizing a first category of the plurality of emergency alerts and consolidating the plurality of emergency alerts of the first category into a consolidated alert. The method includes causing the consolidated alert to be provided to an emergency responder.

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: A wireless network for mobile communications has a connectionless framework using native internet protocol (IP). In this connectionless framework, packet routing may be based on user endpoint (UE) physical IP address, which is associated with the prefix of an associated access node (e.g. eNB). In addition to using the connectionless-IP framework for the traffic flow carried by one access point (e.g. eNB) at a time, advanced mobile call processing features, such as carrier aggregation and dual connectivity, are enhanced to leverage the packet-oriented connectionless radio access network and wireless core network architecture by using the SDN architecture and a wireless network specific software-defined network controller.

Abstract: Concepts and technologies disclosed herein are directed to providing enhanced quality of service (“QoS”) in a software-defined network (“SDN”)-based connectionless mobility architecture. According to one aspect of the concepts and technologies disclosed herein, an SDN controller can receive service level requirements and can map the service level requirements to QoS requirements and attributes to be associated with a QoS tag. The SDN controller can configure a service entry point to insert the QoS tag into incoming packets so that one or more other service points can extract the QoS tag. The other service point(s) can determine, based upon the QoS tag, a QoS treatment to apply to the incoming packets. The other service point(s) can apply the QoS treatment to the incoming packets in accordance with the QoS tag.
