Abstract

Example communication methods and apparatus are described. One example method includes determining a first encapsulation identifier corresponding to an Ethernet session by a control plane network element and sending the first encapsulation identifier corresponding to the Ethernet session to a user plane network element, where the first encapsulation identifier is used to instruct the user plane network element to process a data packet corresponding to the Ethernet session based on the first encapsulation identifier. The terminal device determines the first encapsulation identifier corresponding to the Ethernet session and encapsulates an uplink data packet based on the first encapsulation identifier, where the uplink data packet is a data packet triggered by an application program bound to the Ethernet session. The encapsulated data packet is mapped to the Ethernet session corresponding to the first encapsulation identifier for transmission based on the first encapsulation identifier.

Claims12

Dependent claims

A communication method used to transmit an uplink data packet of an apparatus by using an Ethernet session, wherein the communication method comprises:

after determining that the Ethernet session needs to be established or modified, matching, by the apparatus, an identifier of an application program with a user equipment route selection policy (URSP), wherein the application program is an application program triggering establishment or modification of the Ethernet session, and wherein the URSP comprises a correspondence between an encapsulation identifier and the identifier of the application program;
in response to a determination that the identifier of application program exists in the URSP, obtaining, by the apparatus, the encapsulation identifier based on the correspondence;
determining, by the apparatus, the encapsulation identifier as a first encapsulation identifier corresponding to the Ethernet session;
encapsulating, by the apparatus, the uplink data packet based on the first encapsulation identifier and a media access control (MAC) address of the apparatus to generate an encapsulated data packet, wherein the uplink data packet is a data packet triggered by an application program bound to the Ethernet session;
and
mapping, by the apparatus based on the first encapsulation identifier, the encapsulated data packet to the Ethernet session for transmission.

3 more elements

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 to:
after determining that an Ethernet session needs to be established or modified, match an identifier of an application program with a user equipment route selection policy (URSP), wherein the application program is an application program triggering establishment or modification of the Ethernet session, and wherein the URSP comprises a correspondence between an encapsulation identifier and the identifier of the application program;
in response to a determination that the identifier of application program exists in the URSP, obtain the encapsulation identifier based on the correspondence;
determine the encapsulation identifier as a first encapsulation identifier corresponding to the Ethernet session;
encapsulate an uplink data packet based on the first encapsulation identifier and a media access control (MAC) address of the apparatus to generate an encapsulated data packet, wherein the uplink data packet is a data packet triggered by an application program bound to the Ethernet session;
