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: The present disclosure relates to service packet transmission methods. In one example method, a target user plane network element receives a first uplink service packet from a source user plane, where the first uplink service packet is an uplink service packet received by the source user plane after receiving a second uplink service packet, and the second uplink service packet is the last uplink service packet from the source user plane to a source application server. The target user plane network element receives first indication information, used to indicate that sending of the first uplink service packet by the source user plane network element ends, from the source user plane network element. The target user plane network element sends, to a target AS after the first uplink service packet is sent, an uplink service packet that is from an access network device to the target user plane network element.

Abstract: This application provides a synchronization method and an apparatus, to implement synchronization with a TSN clock in a mobile network. The synchronization method is performed by a first network element in a relay network. The relay network includes a radio access network RAN device and a terminal device. The method includes: The first network element receives a clock synchronization packet. The first network element determines first duration of the relay network, where the first duration of the relay network includes a first downlink transmission delay of transmitting the clock synchronization packet between the RAN device and the terminal device. The first network element determines a time correction field of the relay network, where the time correction field includes the first downlink transmission delay.
