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.
