    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: Systems and methods provide a Multi-access Edge Computing (MEC) traffic breakout service to access an edge network. A network device receives reachability information for a user equipment (UE) device and sends, in response to receiving the reachability information, a reachability notification to a MEC orchestrator for the edge network. The network device receives, from the MEC orchestrator, a local breakout request that identifies a traffic flow authorized to receive local service from the edge network. The network device generates instructions for a gateway device to apply local breakout service, for the traffic flow, to a local MEC application in the edge network and sends the instructions to an anchoring gateway device for the traffic flow.

    Abstract: Systems and methods provide a short data, low latency service using a Multi-access Edge Computing (MEC) network. A network device receives, in a core network, an attach request from an end device and detect whether a packet size range for data transmissions from the end device is within a configured size threshold. The network device directs, when the packet size is within the configured size threshold, routing of the data transmissions via a control plane function of an edge network to a local instance of an application server in the edge network. The network device directs, when the packet size is over the configured size threshold, routing of the data transmissions via a user plane function of the edge network to a local instance of an application server in the edge network.

    Abstract: Systems provide for provisioning, in a wireless network, in a network-service profile associated with a network-service subscriber, at least one of a power saving mode (PSM) parameter or an extended discontinuous reception (eDRX) parameter for use by a first user device; receiving a network service-related request from the first user device via an administrative non-IP packet data network (PDN) bearer established using a statically-allocated non-IP administrative access point name (APN); sending, via the PDN bearer, a first mobile terminated trigger delivery request (MT-TDR) including a bootstrap request trigger, generated by the network device, to the first user device; receiving, via the PDN bearer in response to the bootstrap request trigger, a first mobile originated originating delivery request (MO-ODR) bootstrap request; and sending, in response to the bootstrap request, a second MT-TDR including the at least one of the PSM parameter or the eDRX parameter.

    Abstract: A network device associated with a wireless network receives a network service-related request from a user device. The network device accesses a service profile associated with the user device to determine if the service profile includes preemptive power saving mode (PSM) data that is designated for preempting any user device-requested or network-requested power saving modes at the user device. The network device allocates, if the service profile includes the preemptive PSM data, preemptive PSM timers to the user device based on the preemption PSM data. The network device sends, in response to the network service-related request, an acceptance message to the user device that includes the preemptive PSM timers for use by the user device in executing a power saving mode.
