Abstract
This application provides a communication method and a communications device. The method includes: obtaining a media access control (MAC) address that is of a terminal device and that is bound to a session and first route information of an interface, corresponding to the session, between a user plane function network element and a data network; and sending to an application function network element or a gateway of the data network, the MAC address that is of the terminal device and that is bound to the session and the first route information.
Claims20
An apparatus, comprising:
- at least one processor;
- and
- one or more memories coupled to the at least one processor and storing programming instructions for execution by the at least one processor, the programming instructions instructing the at least one processor to perform operations comprising:
- obtaining a media access control (MAC) address of a terminal and first route information of an interface between a user plane function network element device and a data network, wherein the MAC address is bound to a session, and the interface corresponds to the session;
- and
- sending the MAC address and the first route information to an application function network element device.
A communication system, wherein the system comprises a user plane function network element device and a session management function network element device;
- wherein the user plane function network element device is configured to:
- detect a media access control (MAC) address of a terminal, wherein the MAC address is bound to a session;
- and
- send the MAC address to the session management function network element device;
- and
- wherein the session management function network element device is configured to:
- receive the MAC address from the user plane function network element device;
- obtain first route information of an interface between the user plane function network element device and a data network, wherein the interface corresponds to the session;
- and
- send the MAC address and the first route information to an application function network element device.
A communication system, wherein the system comprises a user plane function network element device and an application function network element device;
- wherein the user plane function network element device is configured to:
- detect a media access control (MAC) address of a terminal, wherein the MAC address is bound to a session;
- and
- send the MAC address to a session management function network element device;
- and
- wherein the application function network element device is configured to:
- receive the MAC address and first route information of an interface between the user plane function network element device and a data network from the session management function network element device;
- and
- determine a transmission path of downlink data based on the first route information, wherein the transmission path is a path from the data network to the user plane function network element device.
