Abstract
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.
