Abstract: The invention relates to a method for constructing an obligate anaerobic Salmonella strain, the obligate anaerobic Salmonella strain constructed by using said method, and the use thereof in tumor therapy.

Abstract: The present disclosure provides a reliability assurance method and a related apparatus. A receiving end device (watchdog) detects a continuous packet loss state, and sends the continuous packet loss state to an access network device, so that the access network device adjusts differentiated scheduling and a reliability assurance policy based on the continuous packet loss state.

Abstract: A subscription information processing method and apparatus, and a device. The method includes: An access control device obtains authorization information from a target network device, where the authorization information includes an identifier of a first terminal and authorization operation indication information for subscription information of the first terminal; the access control device obtains a subscription information processing request from a second terminal, where the subscription information processing request includes an identifier of the second terminal; and the access control device processes subscription information corresponding to the identifier of the second terminal based on the authorization operation indication information in response to the identifier of the first terminal matching the identifier of the second terminal.

Abstract: This application provides a network configuration method and a communications apparatus. The method includes an AC sending configuration status information to a first access point AP, where the configuration status information is used to perform network configuration on the first AP, and the first AP performs network configuration based on the configuration status information sent by the AC, to implement communication between the first AP and a terminal device by using a 3GPP access mode. According to the network configuration method provided in this application, the AC may send the configuration status information to the AP. After performing network configuration, the AP may communicate with the terminal device through a 3GPP air interface.
