  • Patent number: 11452128
    Abstract: Methods for handling uplink transmissions between a user equipment (UE) and a base station in a 5G NR system are described. In implementations, a UE (110) receives, from the base station (120), a first radio resource control message (505) that includes a network-set SkipUplinkTxDynamic field indicating a first configuration for a skip uplink transmission function. The UE determines, regardless of the network-set SkipUplinkTxDynamic field, a user-equipment-set SkipUplinkTxDynamic field (510) that indicates a second configuration for the skip uplink transmission function. The UE transmits, to the base station, a radio resource complete message (515) that includes an indicator of the user-equipment-set SkipUplinkTxDynamic field to override the network-set SkipUplinkTxDynamic field. Afterwards, in various implementations, the UE processes uplink transmissions using the second configuration for the skip uplink transmission function.

  • Patent number: 11444973
    Abstract: A computer method and system for detecting and preventing over-mitigation of network attacks (e.g., Denial of Service (DoS) attacks) upon a protected computer network by a network security element. A determination is made as to whether captured data packets transmitting to a protected network are associated with legitimate network traffic (e.g., non-attack traffic). A matching pattern of the captured data packets determined legitimate network traffic is generated and test traffic packets utilizing the matching pattern of the captured data packets are then generated. The generated test traffic packets are then injected into the network security element/filter. A determination is then made as to whether if the injected test traffic packets are treated as a malicious traffic (e.g., a DoS attack), or as legitimate traffic, by the network security filter. If treated as malicious traffic (e.g.

    Abstract: Space system TT&C monitoring includes analyzing network traffic comprising of data packets between a front-end processor (FEP) and a cryptographic unit. A JavaScript Object Notation (JSON) object is created when the network traffic containing a vehicle command is detected. The JSON object is transmitted, by way of a data transport mechanism, to either a cyber defense module or a security information and event management (SIEM) module for further ingestions and visualization. The JSON object is analyzed using machine learning (ML) module or a rule-based intrusion detection system (IDS) module to generate an anomaly score for the SIEM module for further ingestions and visualization.

  • Patent number: 11418279
    Abstract: In a busy 5G/6G wireless network, message collisions may occur in which an “intruder” signal is transmitted at the same time as a “subject” message, rendering one or more of the subject message elements distorted. Modulation schemes are disclosed in which the corrupted message elements may be recovered, without requesting a retransmission. The modulation states have the property that, if two of the modulation states are combined by superposition, the resulting signal does not resemble any of the modulation states. Hence the receiver can determine, from the received signal, which message elements are collided, and can also identify the original modulation state of the subject message element in many cases. By replacing the collided message elements with the originally intended modulation state, the receiver may demodulate the subject message correctly while avoiding the delays and costs involved in requesting a retransmission, according to some embodiments.

  • Patent number: 11411858
    Abstract: This application provides a method for updating a route in a network. The first network device sends a first LSA packet to a third network device, so that the third network device generates a first route whose destination address is a second IP address, where a next-hop IP address of the first route is the IP address of the first network device, and the second IP address belongs to the IP network segment corresponding to the first IP address which is an IP address of the first network device. The first network device sends a second LSA packet to the third network device when determining that switching needs to be performed on a next hop of a route in the third network device, whose destination address belongs to the IP network segment, and whose next-hop IP address is the first IP address.

  • Patent number: 11398876
    Abstract: Message failures due to noise and interference cause unnecessary delays and reduction in reliability in wireless networks. To detect, localize, and correct transmission faults in 5G and 6G networks, the receiver can measure the “modulation quality” of each message resource element modulated in PAM (pulse-amplitude modulation), according to how closely the amplitudes of the in-phase and quad-phase signal branches match the amplitude levels of the modulation scheme. If the message is faulted, the receiver can re-assign each message element with poor modulation quality to the adjacent states, or if necessary to each state in the modulation scheme, and may thereby find the correct message value in many cases. When implemented, message fault mitigation as disclosed herein can resolve message failures, improve communication reliability, reduce latency, and improve network operations overall, according to some embodiments.
