Abstract: This application provides example path switching methods, example communication apparatuses, and example communication systems. One example method includes obtaining, by a session management network element, a context of a first transport layer connection, where the first transport layer connection is between a source transport layer proxy network element and a terminal device. In response to determining that a protocol data unit (PDU) session anchor for the terminal device needs to be changed, the session management network element can send the context of the first transport layer connection to a target transport layer proxy network element, where the context is used to establish a third transport layer connection between the target transport layer proxy network element and the terminal device.

Abstract: 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.

Abstract: 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.

Abstract: A quality of service (QoS) parameter processing method and a system, where the method includes a session management function device obtaining a core network (CN) packet delay budget (PDB) between a first access network device and a first user plane function device, and sending the CN PDB to the first access network device via a context update response message, where the first access network device is a target access network device serving a terminal device after a handover. After receiving the CN PDB, the first access network device determines an access network (AN) PDB between the terminal device and the first access network device based on the CN PDB and an end-to-end PDB between the terminal device and the first user plane function device, and then schedules an air interface resource between the terminal device and the first access network device based on the AN PDB.
