1. A packet delay parameter obtaining method, comprising:
determining, by the session management network element, whether a first quality of service (QoS) flow satisfies a parameter condition that a first parameter of the first QoS flow is identical to a first parameter of a first service flow, the first parameter of the first QoS flow indicating information corresponding to a protocol data unit session anchor (PSA) user plane function (UPF) transmitting the first QoS flow and corresponding to a PSA UPF transmitting the first service flow;
establishing, by the session management network element, a second QoS flow for the first service flow when the first QoS flow does not satisfy the parameter condition; and
sending, by the session management network element, a first message to an access network element, wherein the first message comprises identification information of the second QoS flow and a packet delay parameter corresponding to the second QoS flow.
