Abstract: This specification discloses a communication method, and a system. The method includes: receiving, by a first control network element, analysis information of a network data analytics network element NWDA, and generating a policy based on the analysis information; sending, by the first control network element, the policy to a second control network element, where execution of the policy is controlled by the second control network element; receiving, by the first control network element, an execution result of the policy that is sent by the second control network element, and determining, based on the execution result, whether the analysis information is invalid; and sending, by the first control network element, an invalidity notification message to the NWDA when the first control network element determines that the analysis information is invalid, where the invalidity notification message is used to instruct the NWDA to generate new analysis information.

Abstract: A packet delay parameter obtaining method, apparatus, and system are provided. The method provides a session management network element determines whether a first QoS flow satisfying a parameter condition exists, where the first parameter indicates information corresponding to a PSA UPF transmitting the first QoS flow, the first parameter indicating information corresponding to a PSA UPF transmitting the first service flow. If no first QoS flow satisfying the parameter condition exists, a second QoS flow for the first service flow is established, and the session management network element sends a first message to an access network element, the first message including identification information of the second QoS flow and a packet delay parameter corresponding to the second QoS flow.
