    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 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 configured to store instructions and a processor configured to execute the instructions to detect a Session Initiation Protocol (SIP) call and identify an available technology type to carry the SIP call from an originating device. The processor may be further configured to execute the instructions to generate an originating available technology type header that includes information identifying the identified available technology type to carry the SIP call from the originating device and forward the SIP call toward a destination with the generated originating available technology type header.

    Abstract: A device receives information associated with a voice-over-long term evolution (VoLTE) call from multiple network devices that handle the VoLTE call and that are provided in an evolved packet system (EPS). The device identifies particular parameters from the information associated with the VoLTE call, and combines the particular parameters into an end-to-end call record for the VoLTE call. The device outputs or stores the end-to-end call record for the VoLTE call.

    Abstract: A method, a network device, a system, and a non-transitory computer-readable storage medium are described in relation to an RAT type monitoring event service. The RAT type monitoring event service may include providing a current RAT type associated with an end device and a network to an application function. The RAT type monitoring event service may also include providing a notification to the application function when the end device changes its RAT type. The current RAT type may be used by the application function to perform a network operation or procedure. The application function may subscribe to a monitoring and event notification associated with the RAT type monitoring event service.
