  • Publication number: 20230208679
    Abstract: Embodiments of this application disclose a tunnel keepalive method, a network device, a system, and a storage medium, and pertain to the field of communications technologies. In the embodiments of this application, before a failure occurs in communication between a UP device and a CP device, the UP device receives tunnel information synchronized by the CP device. After a failure occurs in communication between the UP device and the CP device, the UP device performs tunnel keepalive based on the tunnel information, that is, the UP device maintains a tunnel between the UP device and a remote network device. In this way, tunnel teardown is not triggered because of the failure in communication between the CP device and the UP device.

  • Publication number: 20220078122
    Abstract: This application discloses a method and an apparatus for accessing a gateway, and pertains to the field of communications technologies. A service level agreement (SLA) level may be obtained based on user information of a terminal, and further a user plane (UP) device corresponding to the terminal is determined based on the SLA level of the terminal. Thus, terminals with different SLA levels may be allocated to different UP devices for bearing, so that a specific terminal may access a specified UP device. This resolves a problem in a related technology that a terminal relatively randomly accesses a UP device. In addition, because an SLA level may be used to indicate a level of quality of service of a terminal, after terminals with different SLA levels access different UP devices, differentiated services may be provided on the different UP devices. Therefore, user requirements are met, and revenues are increased.
