Communications method and apparatus

An SMF network element determines, according to a PCC rule of a flow, a third latency of transmitting the flow from a UPF network element to UE, so that a second latency of transmitting the flow from a flow service provider in a TSN to the UE can be determined based on the third latency and a first latency of transmitting the flow from the flow service provider in the TSN to the UPF network element.

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.

Embodiments of this application provide a packet transmission method, a communication apparatus, and a communication system. A target transport layer proxy network element establishes a fourth transport layer connection based on a first context of a source transport layer proxy network element, where the first context is a context about packet transmission of the source transport layer proxy network element on a first path. If the target transport layer proxy network element receives first indication information, and the first indication information indicates that application context migration between a first application server and a second application server is completed, the target transport layer proxy network element performs transport layer processing on a packet on a second path based on a second context of the target transport layer proxy network element, and transmits, on the second path, a packet obtained through the transport layer processing. Hence, a packet loss can be avoided.
