Abstract: A device may include a processor configured to establish a data traffic flow for a user equipment (UE) device and determine per flow descriptor attributes associated with the data traffic flow, wherein the per flow descriptor attributes identify at least a source, a destination, and a protocol associated with the data traffic flow. The processor may be further configured to determine at least one additional per flow descriptor attribute for the data traffic flow and send the per flow descriptor attributes and the at least one additional per flow descriptor attribute to a network exposure device of a core network, wherein the network exposure device is configured to communicate with servers outside the core network.

Abstract: A method, a device, and a non-transitory storage medium are described in which a network slice usage subscription service is provided. The network slice usage subscription service may allow a network device to obtain network slice usage information and event notifications. The event notification may indicate when an end device is using a network slice and when the end device is no longer the network slice. The network device may include an application function (AF) device. The network device may use the event notification to perform an operation relating to the network slice and/or the end device.

Abstract: A method, a device, and a non-transitory storage medium are described in which a network slice usage service is provided. The network slice usage service may allow a network device to obtain a network slice usage value of a network slice. The network device may calculate a network slice load value based on the network slice usage value. The network device may also provide the network slice load value to other network devices of a core network.

Abstract: A network device receives, from a congestion controller, traffic policy information associated with a data stream between a sender and a receiver, where the traffic policy information includes a maximum round trip delay time (RTT) and a maximum throughput rate (Rate). The network device obtains a receiver advertised window size (RWND) for the receiver for the data stream. The network device modifies the RWND based on the RTT and the Rate to produce a modified receiver window size (RWND?) and sends the RWND? to the sender for use in controlling congestion on the data stream between the sender and the receiver.

Abstract: Systems and methods provide for network-based selection of a UE device's 5G operation mode. A network device in a wireless core network receives a policy query for a user equipment (UE) device. The UE device is capable of 5G non-standalone (NSA) and 5G standalone (SA) operation modes. The network device identifies one or more of subscription data for the UE device, stored network data associated with the UE device, or dynamic network data relevant to the UE device. The network device assigns, based on the identifying, a radio access technology/frequency selection and prioritization (RFSP) value for the UE device. The network device sends the RFSP value to an access management function in the wireless core network for controlling selection of the 5G NSA operation mode or 5G SA operation mode.

Abstract: A packet destined for a Multi-access Edge Computing (MEC) network is received at a wireless station from a user device. A serving gateway (SGW) receives the packet from the wireless station via an S1U GTP tunnel and assigns an uplink S1U General Packet Radio Service (GPRS) Tunneling Protocol (GTP) tunnel endpoint identifier (TEID) to the packet. The SGW performs a network address translation (NAT) function on the packet based on the uplink S1U GTP TEID assigned to the packet to form a translated packet. The SGW transmits the translated packet to the MEC network.

The processor may be further configured to intercept messages associated with the microservice for the network function using the configured service proxy container; and apply the wireless network policy to the intercepted messages using the configured service proxy container.

Abstract: A system described herein may provide a technique for location-based handling of discovery requests in a service-based network in which different instances of network functions (“NFs”) may be deployed in geographically diverse locations. For example, a Network Repository Function (“NRF”) may maintain location information for the various NF instances and may respond to discovery requests by identifying particular NF instances based on locations associated with the discovery requests. For example, such discovery requests may include a “preferred-locality” parameter or some other indication of location associated with the discovery request, based on which the NRF may identify one or more NF instances to provide in response to the discovery request.

Abstract: An edge network gateway, located in an edge network and connected to a core network, receives packets for a local breakout (LBO) Protocol Data Unit (PDU) session associated with a mobile subscriber. The edge network gateway sends, based on receipt of the packets for the LBO PDU session, a request for charging to a core network node, and forwards the packets for the LBO PDU session to a network or multi-access edge computing (MEC) data center connected to the edge network. The edge network gateway sends, via an online charging interface, charging data counts for the packets of the LBO PDU session to the core network node for reporting to an Online Charging System and charging to the mobile subscriber.

Abstract: A network device includes a network interface for establishing a communication session with another network device, a memory to store instructions, and a processor to execute the instructions. The processor may, for each time period during the communication session, adjust a size of a receive buffer of a socket. When the processor adjusts the size, the processor, if a utilization number of the receive buffer is greater than a high threshold: may determine a first new size for the receive buffer, and set a size of the receive buffer to the first new size. If the utilization number is less than a low threshold, the processor may determine a second new size for the receive buffer; and set the size of the receive buffer to the second new size.

Abstract: Network devices may receive a Transport Control Protocol (TCP) segment from a user device. The TCP segment includes a TCP header and a payload, and the payload includes either a Hypertext Transfer Protocol (HTTP) plaintext message or a Secure HTTP (HTTPS) encrypted message. The network devices may extract a TCP Synchronization (SYN) signature from the TCP header and determine whether the payload of the TCP segment includes a HTTP plaintext message or a HTTPS encrypted message. When the payload includes a HTTP plaintext message, the network devices may extract contents of a HTTP User-Agent field from the HTTP plaintext message, determine a device type identifier (ID) and a category ID based on the extracted contents, and update a plurality of device signatures based on the TCP signature, the device type ID, and the category ID.

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 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.
