    Abstract: Systems described herein provide techniques for establishing and modifying user plane communications sessions between Long-Term Evolution (“LTE”) User Equipment (“UE”) devices, connected to LTE base stations, and a Fifth Generation (“5G”) core network. An LTE-5G Interworking function (“LTE-5G IWF”) may logically generate a virtual 5G UE and/or 5G base station, map a LTE UE to the virtual 5G UE, and cause the establishment of a Protocol Data Unit (“PDU”) Session, at the 5G core network, with the virtual 5G UE. The LTE-5G IWF may provide PDU Session information to the LTE UE and base station to facilitate the establishment of user plane communications (e.g., via a tunnel) between the LTE UE and the 5G core network. The LTE-5G IWF may also receive modification parameters, such as Quality of Service (“QoS”) parameters, and provide instructions to the 5G core and/or to the LTE UE to handle traffic according to such parameters.

    Abstract: A computer device may include a memory storing instructions and processor configured to execute the instructions to receive a session request from an application function (AF) device for a user equipment (UE) device and select a network slice based on the AF device. The computer device may be further configured to send a slice selection trigger to an Access and Mobility Function device for the UE device in response to selecting the network slice, wherein the slice selection trigger includes an instruction to UE device to request the selected network slice; receive a notification from a User Plane Function device associated with the selected slice, wherein the notification identifies a Packet Data Unit session between the UPF device and the UE device; and instruct the AF device to start a session with the UE device via the identified PDU session.

    Abstract: A computer device may include a memory storing instructions and a processor configured to execute the instructions to select a broadcast method for a wakeup signal for a wireless communication device; instruct a base station to broadcast the wakeup signal using the selected broadcast method; and provide information identifying the selected broadcast method to the wireless communication device. The processor may be further configured to receiving a wakeup request from a machine-type communication interworking function (MTC-IWF) device; map the received wakeup request to a wakeup signature beacon signal associated with the wireless communication device; and instruct the base station to transmit a wakeup signature beacon signal to the wireless communication device based on the received wakeup request.

An LTE-5G Interworking function (“LTE-5G IWF”) may logically generate a virtual 5G UE and/or 5G base station, map a LTE UE to the virtual 5G UE, and cause the establishment of a Protocol Data Unit (“PDU”) Session, at the 5G core network, with the virtual 5G UE. The LTE-5G IWF may also maintain a 5G context, including the information of the virtual 5G UE and/or 5G base station, based on the actual location of the LTE UE and/or an LTE base station to which the LTE UE is connected. The LTE-5G IWF may further update this context, including location information, when the LTE UE is handed over from one LTE base station to another.

    Abstract: A device obtains a list of a plurality of user devices from a first network device and receives a message intended for a destination user device from a second network device. The device obtains information indicating that the destination user device can receive messages that conform to a particular format from a third network device and converts the message to the particular format. The device determines a reachability of the destination user device based on the list of the plurality of user devices, after converting the message, and sends the message to the destination user device via the first network device based on the reachability. The device receives a delivery message from the destination user device and sends a notification message indicating successful delivery of the message to the second network device based on the delivery message.

    Abstract: Systems described herein ensure authorized communications between application servers and machine-type communications (MTC) devices. The systems store a subscriber profile for an MTC device, the subscriber profile including application server (AS) configuration information designating application servers that are authorized to connect with the MTC device. The systems receive a non-IP data delivery (NIDD) registration request from an application server, wherein the NIDD registration request includes an identifier for the MTC device. The systems obtain, from the application server, a first identifier for the application server, and retrieve, based on the NIDD registration request, the AS configuration information from the subscriber profile. The systems determine if there is a match between the AS configuration information and the first identifier for the application server, and configure a binding of the application server and an access point name (APN) for the MTC device in response to determining that there is a match.
