  • Publication number: 20190080084
    Abstract: A virtual network function (VNF) audit method and apparatus, used to audit a VNF generated by a platform that includes an authentication and authorization component, a service component, and a virtualized infrastructure. The method includes receiving an event reported by the authentication and authorization component, receiving an event reported by the service component, and receiving an event reported by the virtualized infrastructure, obtaining an event occurrence sequence of each VNF according to all received events, and auditing the event occurrence sequence of each VNF to obtain an audit result of the VNF. According to the method, the events that are distributed in different components are integrated into one event occurrence sequence in order to visually and quickly detect a malicious VNF generated by bypassing a component, and more comprehensively detect the malicious VNF, thereby reducing a missed detection rate of a VNF operation audit.

  • Patent number: 10193675
    Abstract: A method and a device for notifying reference signal configuration information are disclosed. Channel state information-reference signal (CSI-RS) configuration information is coded, to obtain a CSI-RS configuration information code. A mapping relation between the CSI-RS configuration information code and the CSI-RS configuration information is stored. A CSI-RS configuration information code corresponding to CSI-RS configuration information to be notified is searched in the stored mapping relation between the CSI-RS configuration information code and the CSI-RS configuration information. The searched CSI-RS configuration information code is sent to a user equipment (UE), so that the UE determines CSI-RS configuration information according to the received CSI-RS configuration information code and the mapping relation between the CSI-RS configuration information code and the CSI-RS configuration information.
