In a process in which a terminal device accesses a network, if a control plane network element determines that a fault occurs on a steering decision-making network element, to ensure that the terminal device can continue to access the network, the control plane network element may directly control, without decision of the steering decision-making unit, the terminal device to send a data packet through a first user plane network element for a dial-up request.

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.
