Abstract
Provided are an information transmission method and apparatus, and a communication device. The method comprises: a first device entity acquiring header information of an Ethernet data packet from a second device entity, wherein the header information of the Ethernet data packet comprises first indication information, and the first indication information is used for indicating whether the header information of the Ethernet data packet includes a target information domain.
Claims11
A method for transmitting information, comprising:
- acquiring, by a first device entity, header information of an Ethernet data packet from a second device entity, wherein the header information of the Ethernet data packet comprises first indication information, and the first indication information is used for indicating whether the header information of the Ethernet data packet contains a target information field;
- wherein acquiring, by the first device entity, the header information of the Ethernet data packet from the second device entity comprises:
- acquiring, by the first device entity, the header information of the Ethernet data packet from the second device entity through a control plane;
- wherein
- acquiring, by the first device entity, the header information of the Ethernet data packet from the second device entity through a first interface, wherein the first interface is an interface between the first device entity and the second device entity;
- or,
- acquiring, by the first device entity, from a third device entity, the header information of the Ethernet data packet from the second device entity through a second interface, wherein the second interface is an interface between the first device entity and the third device entity;
- wherein when the first device entity acquires from the third device entity the header information of the Ethernet data packet from the second device entity through the second interface,
- the header information of the Ethernet data packet is transmitted through a specific first user plane tunnel, wherein the first user plane tunnel is a user plane tunnel between the first device entity and the third device entity;
- wherein the specific first user plane tunnel is a GTP-U tunnel, and the GTP-U tunnel is identified by a GTP-U address.
