Abstract: Dynamically switching between broadcast and unicast services for service continuity between wireless networks is presented herein. A system can comprise a detection component configured to determine that a mobile device is receiving a broadcast transmission of broadcast data from a broadcast enabled access point device configured to send, via a broadcast service wireless coverage area, the broadcast data to multiple devices via a point-to-multipoint communication protocol. Further, the detection component can detect a movement of the mobile device from the broadcast service wireless coverage area to a unicast service wireless coverage area. A transfer component can initiate, in response to the detection, a unicast transmission of the broadcast data from a unicast enabled access point device to the mobile device—the unicast enabled access point device configured to send, via the unicast service wireless coverage area, the broadcast data to a single device via a point-to-point communication protocol.

Abstract: A system that incorporates the subject disclosure may include, for example, receive a subscription from an application server where the subscription identifies a session event and/or sub-events occurring in a communication session for which the application server requests user location information, provide subscription information based on the subscription to core network nodes of the mobile communications network, receive user location information from the core network nodes responsive to a detection of a triggering event corresponding to the session event of the subscription, and provide the user location information to an IP multimedia subsystem network for delivery to the application server. Other embodiments are disclosed.

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: 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.

Abstract: Aspects of the subject disclosure may include, for example, a device that determines each of a default downlink forwarding address of a first interface of a user plane and a currently used downlink forwarding address of the first interface of the user plane. One of an uplink user data packet comprising an origination address of a second interface of the user plane, a downlink user data packet comprising a destination address of the second interface of the user plane or both are received, by way of the user plane. One of the default downlink forwarding address, the currently used downlink forwarding address or both can be modified based on the uplink origination address, the destination address or both. Modification of the default downlink forwarding address, the currently used downlink forwarding address or both results in a redirection of an associated packet flow within the user plane. Other embodiments are disclosed.

Abstract: A subscriber management system for maintaining active communication sessions during subscriber maintenance activities is provided. The system can delay detaching mobile devices from the mobile network when there are active communication sessions that are associated with subscriber management maintenance activities or customer care activities in order to avoid disrupting the subscriber experience. The system can delay deleting the subscriber information until the active sessions have ended, which will allow the customer care activities to continue uninterrupted. In an embodiment, the subscriber management system can determine whether to detach the active communication session based on the priority of the session, such as whether it is real-time, or with a customer care element of the mobile network.
