  • Patent number: 12107873
    Abstract: The invention discloses a blockchain-based intrusion detection system for railway signal, which is built on a blockchain's distributed chain structure, without a central, trusted control center. This design mitigates the vulnerabilities associated with centralized intrusion detection centers. Additionally, by utilizing a blockchain-based distributed structure, it also eliminates the risk of a single point of failure for the intrusion detection center. Moreover, the data within the blockchain-based intrusion detection system is highly resistant to malicious tampering. This is achieved by leveraging the consensus mechanism inherent in the blockchain, which can achieve consensus among intrusion detection nodes. The current invention solves the internal evil attacks and avoid the inability to reach consensus between nodes due to internal evil, thereby affecting the intrusion detection performance; at the same time, the intrusion detection model can resist external network attacks.

  • Publication number: 20240323768
    Abstract: Embodiments described herein relate to managing access to 5G cellular baseband resources for 5G-capable wireless devices. A 5G-capable wireless device of an MNO, while connected to or camped on a legacy 4G LTE cell of the MNO and not engaged in a 4G only LTE service, determines whether an NSA 5G cell of another MNO satisfies performance criteria before measuring and/or sending measurement data for an NSA 4G LTE anchor cell associated with the NSA 5G cell to a wireless network. Refraining from measuring and/or sending measurement data under certain conditions causes the 5G-capable wireless device of the MNO to remain connected to or camped on the legacy 4G LTE cell of the MNO rather than reselecting or handing over to the NSA 4G LTE cell of another MNO. The 5G-capable wireless device also maintains a database of information for valid NSA 4G LTE cells to which to reselect/handover.
