Abstract: A network device can receive a request from an application server for availability information associated with a response period in which a user equipment is responsive to communications. The network device can send a status query related to the user equipment to a radio access network controller device that processes signals between the user equipment and a mobile network core device. The network device can receive the availability information from the radio access network controller device and transmit a notification message to the application server that indicates the response period.

Abstract: One or more protocols between a control plane entity (e.g., a mobility management entity (MME)) and its peer nodes (e.g., mobile switching center (MSC) and/or short message service center (SMSC)) are enhanced to improve short messaging services for Internet of things (IoT) devices. Oftentimes, IoT devices enter an extended sleep mode during which they cannot be reached by the control plane entity. In one aspect, the control plane entity can determine a wait period based on information, such as, but not limited to, device context data, mapping tables, policy data, commercial traffic data, latency data, device delay tolerance, sleep mode timer values, etc. The wait period can be provided to the peer nodes, which can utilize the wait period to control one or more message retry mechanisms based on IoT device behaviors resulting in an improvement of overall IoT service behaviors and a delivery of superior IoT customer experience.

Abstract: Specialized, service optimized virtual machines are assigned to handle specific types of Internet of Things (IoT) devices. An IoT context mapping policy engine within the context of a virtualized network function manages IoT context mapping policy functions in load balancers. The IoT context mapping policy functions select service optimized virtual machines based on IoT device IDs, and assign those virtual machines to handle the devices. The IoT context mapping policy functions provide load data to the IoT context mapping policy engine. Based on the load data, the IoT context mapping policy engine maintains appropriate scaling by creating or tearing down instances of the virtual machines.

Abstract: Critical radio resources can be intelligently and dynamically managed across traditional consumer mobility and Internet of things (IoT) services in an end-to-end manner. A selective offloading scheme based on monitored traffic dynamics can be utilized to ensure that IoT traffic is steered, on-demand, to a customized and/or dedicated core network slice, thereby enhancing consumer and IoT services experience. In one example, within the IoT domain, traffic can be steered to the customized and/or dedicated core network slice based on various factors, for example, device category and/or congestion per radio carrier, to minimize service disruptions and deliver superior mobility network functionality and/or end-user experience.

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: In order to dynamically allocate spectrum resources to broadcast and unicast operations, user equipment (UE) sends a start message to a broadcast multicast tracking application in response to the UE deciding to start receiving a content stream. The start message includes cell site information where the user equipment is located and a channel identification indicating the content stream. The tracking application tracks the number of active listeners to the content stream in the cell and based on the number of active listeners and cell utilization, determines whether to initiate a broadcast. If the broadcast is initiated, the tracking application sends a message to the UE to retune to a broadcast channel. The UE sends a stop message when the UE decides to stop receiving the content stream and the tracking application and determines whether to terminate the broadcast based on the remaining active listeners and the cell utilization.
