Abstract: The present disclosure relates to user plane information reporting methods and apparatus. In one example method, a session management network element obtains parameter information, and initiates establishment of a dedicated tunnel between a first communications apparatus and a second communications apparatus, where the parameter information indicates the first communications apparatus to report user plane information when a reporting condition is met. The session management network element sends a first rule to the first communications apparatus, where the first rule indicates the first communications apparatus to send a packet to the second communications apparatus through the dedicated tunnel when the reporting condition is met.
