Abstract: 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.

Abstract: This application provides a communication method, wherein a user plane path between a terminal and a user plane gateway includes a first link and a second link, the first link is a link between the terminal and an access network device, and the second link is a link between the access network device and the user plane gateway. The method comprises: obtaining packet loss statuses of a service flow on the first link and the second link; determining a quantity of consecutive lost packets of the service flow on the user plane path based on the packet loss statuses of the service flow on the first link and the second link; and when the quantity of consecutive lost packets of the service flow on the user plane path reaches a first threshold, triggers enabling of a high-reliability transmission mechanism for the service flow.
