摘要： This application provides a downlink transmission method. A session management network element obtains duration, namely, a first delay, between an expected moment at which a downlink service packet arrives at an access network element and an estimated moment at which the downlink service packet arrives at the access network element, the expected moment is within a first scheduling window, and a next scheduling window adjacent to the first scheduling window is a downlink scheduling window. Then, the session management network element sends the first delay to an application network element, where the first delay is used by an application server to determine a second moment at which the downlink service packet is sent, and a moment at which the downlink service packet sent at the second moment arrives at the access network element is within the first scheduling window.

摘要： A communication method and apparatus are provided for transmitting packets of a data stream between user equipment. After receiving a first packet from a first user equipment, a user plane function (UPF) forwards the first packet to a second user equipment at a first moment, so that the first packet that arrives at the UPF before the first moment is not forwarded to the second user equipment until the first moment, to support deterministic sending and ensure that a time sensitive communication (TSC) packet is sent at a determined moment, so as to provide deterministic delay assurance for applications such as industrial control and telemedicine.
