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.

Abstract: Embodiments of the present disclosure provide a policy control method and system, a network element, and a storage medium. A control plane network element establishes, for UE, a first DN connection that uses a first forwarding plane network element as an anchor. The method includes: when the control plane network element receives a handover notification message for the UE and determines that a second forwarding plane network element serves the UE, or when the control plane network element establishes, for the UE, a second DN connection that uses a second forwarding plane network element as an anchor, the control plane network element updates a forwarding path of the first DN connection, so that an updated forwarding path of the first DN connection passes through the second forwarding plane network element, and the second forwarding plane network element performs policy control on a packet on the first DN connection.

Abstract: A control method for collecting traffic statistics includes a control node obtains a statistics collection instruction, where the statistics collection instruction is used to instruct to collect traffic statistics of a target data flow, generates a traffic statistics collection policy according to the statistics collection instruction, where the traffic statistics collection policy includes a matching identifier of the target data flow, a first command, and a second command, and sends the traffic statistics collection policy to a forwarding node. The first command is used to instruct the forwarding node to set a traffic identifier for the target data flow based on the matching identifier, the second command is used to instruct the forwarding node to add traffic generated by a target packet to a traffic statistics collection result corresponding to the traffic identifier which is used to describe the traffic of the target data flow.
