A first edge configuration server receives a first request message, sends an application function request message to a policy control function network element, and sends a response message for the first request message. The first request message includes an application client profile. The application function request message is used to request to configure a data forwarding path from a terminal to a visited edge enabler server and/or a visited edge configuration server. In embodiments of this application, data sent by the terminal to the visited edge enabler server and/or the visited edge configuration server may be distributed to a visited domain via a visited user plane function network element, instead of being forwarded to a home user plane function network element.
