Abstract: In one example, a method and apparatus for dynamic routing of user contexts are disclosed. In one example, a method for supporting a context associated with a connection between a user and a first virtual machine of a virtual function includes receiving a notification of a change in a behavior of the user that affects the context, wherein the context is supported by the first virtual machine of the virtual function, and reassigning the context to a second virtual machine of the virtual function, different from the first virtual machine, based at least in part on the change in the behavior.

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.

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: 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: 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: Aspects of the subject disclosure may include, for example, determining a request to transfer data to a group of wireless communication devices within an area. Wireless base stations of a wireless mobility network are identified, responsive to the request, wherein the wireless base stations provide wireless communication services within the area, including a Multimedia Broadcast Multicast Service (MBMS) service. A wireless transmission is facilitated of a first broadcast message by the wireless base stations, wherein the first broadcast message identifies the group of wireless communication devices. The broadcast message is transmitted by way of the MBMS service of the wireless communication services. The first broadcast message initiates a state transition to an active state for a plurality of wireless communication devices of the group of wireless communication devices configured in an idle state. Other embodiments are disclosed.

Abstract: Concepts and technologies disclosed herein are directed to an enhanced data download mechanism for power constrained Internet of Things (“IoT”) devices. An IoT file share server can receive an update file from an IoT application server. The IoT file share server can calculate a file chunk size based upon a device type of the IoT device and a file size of the update file. The file chunk size can be calculated such that each file chunk of a plurality of file chunks is downloadable to the IoT device in a single awake period of the IoT device. The IoT file share server can partition the update file into a plurality of file chunks to be sent to the IoT device, each of which can include a portion of the update file, and the portion can be of the file chunk size.
