Abstract
A communication method includes, after determining first session identifier information for a terminal device and obtaining an address of the terminal device, a session management network element sends a first correspondence between the first session identifier information and the address of the terminal device to a first user plane function network element, so that the first user plane function network element transmits an Ethernet packet to the terminal device based on the first correspondence.
Claims21
A communication method comprising:
- obtaining, by a session management network element, first session identifier information for a terminal device and comprising a tunnel endpoint identifier;
- obtaining, by the session management network element from a source user plane function network element, an address of the terminal device, wherein the address of the terminal device is a media access control (MAC) address of the terminal device, and wherein the terminal device is handed over from the source user plane function network element to a new user plane function network element;
- generating, by the session management network element, a packet transmission rule indicating to the new user plane function network element how to transmit an Ethernet packet and comprising a correspondence between the first session identifier information and the MAC address of the terminal device;
- and
- sending, by the session management network element to the new user plane function network element, the packet transmission rule,
- wherein the first session identifier information indicates a first session channel of the new user plane function network element.
