Abstract

The present disclosure discloses a method, wherein the method comprises generating a passive optical network (PON) protocol message, wherein the PON protocol message comprises an identifier of a PON user terminal and an action indication indicating that the PON user terminal intends to exercise a first power supply mode that is a power-saving mode. The present disclosure further provides a method for controlling the PON power supply and for reporting the power supply state. The present disclosure allows control of the energy usage of the PON user terminal to save power when a service in the PON user terminal is not used or when the user terminal uses a backup power source to supply power.

Claims

1. A method, comprising:

generating a first passive optical network (PON) protocol message, wherein the first PON protocol message comprises a first action indication indicating that the PON user terminal intends to exercise a first power supply mode that is a power-saving mode, wherein the first power supply mode is operated at lower power than a power provided in a second power supply mode, wherein in the second power supply mode, a power supply is provided to the PON user terminal such that the PON user terminal can provide service data from an optical line termination (OLT) to a user and communicate with the OLT via an established upstream connection;

sending the first PON protocol message;

entering the PON user terminal in the first power supply mode, wherein in the first power supply mode, both upstream communication and downstream communication with the OLT are disabled to break, while retaining the ability to switch from the first power supply mode to the second power supply mode.

2. The method of claim 1, wherein the method further comprises:

sending a second PON protocol message from the PON user terminal in the first power supply mode, wherein the second PON protocol message comprises a second action indication indicating that the PON user terminal intends to be operated in the second power supply mode.

3. The method of claim 1, wherein in the first power supply mode, the PON user terminal is inactive in providing service data to the user.

4. The method of claim 1, wherein in the first power supply mode, an upstream PON interface unit (PONIU) of the PON user terminal is turned off and the established upstream connection is disconnected, and the PON user terminal is configured to detect whether the upstream PONIU is reactivated and an upstream connection with the OLT is reestablished.

5. The method of claim 1, wherein the first PON protocol message and the second PON protocol message are physical layer operation administration maintenance (PLOAM) message or an Optical Network Terminal management and control interface (OMCI) message.

6. A method, comprising:

receiving a first passive optical network (PON) protocol message, wherein the first PON protocol message comprises a first action indication indicating that the PON user terminal intends to exercise a first power supply mode that is a power-saving mode, wherein the first power supply mode is operated at lower power than a power provided in a second power supply mode, wherein in the second power supply mode, a power supply is provided to the PON user terminal such that the PON user terminal can provide service data from an optical line termination (OLT) to a user and communicate with the OLT via an established upstream connection.

7. The method of claim 6, further comprising:

receiving a second PON protocol message from the PON user terminal in the first power supply mode, wherein the second PON protocol message comprises a second action indication indicating that the PON user terminal intends to be operated in the second power supply mode.

8. The method of claim 6, further comprising:

recording the first power supply mode in the PON user terminal for saving energy when the PON user terminal in the first power supply mode.

9. The method of claim 6, wherein the first PON protocol message and the second PON protocol message are physical layer operation administration maintenance (PLOAM) message or an Optical Network Terminal management and control interface (OMCI) message.

10. A passive optical network (PON) component, comprising a processor which is configured to:

generate a first passive optical network (PON) protocol message, wherein the first PON protocol message comprises a first action indication indicating that the PON user terminal intends to exercise a first power supply mode that is a power-saving mode, wherein the first power supply mode is operated at lower power than a power provided in a second power supply mode, wherein in the second power supply mode, a power supply is provided to the PON user terminal such that the PON user terminal can provide service data from an optical line termination (OLT) to a user and communicate with the OLT via an established upstream connection;

send the first PON protocol message; and

enter the PON user terminal in the first power supply mode, wherein in the first power supply mode, both upstream communication and downstream communication with the OLT are disabled to break, while retaining the ability to switch from the first power supply mode to the second power supply mode.

11. The PON component of claim 10, wherein the PON component is configured to send a second PON protocol message from the PON user terminal in the first power supply mode, wherein the second PON protocol message comprises a second action indication indicating that the PON user terminal intends to be operated in the second power supply mode.

12. The PON component of claim 10, wherein in the first power supply mode, the PON component is inactive in providing service data to the user.

13. The PON component of claim 10, wherein in the first power supply mode, an upstream PON interface unit (PONIU) of the PON component is turned off and the established upstream connection is disconnected, and the PON component is further configured to detect whether the upstream PONIU is reactivated and an upstream connection with the OLT is reestablished.

14. The PON component of claim 10, wherein the first PON protocol message and the second PON protocol message are physical layer operation administration maintenance (PLOAM) message or an Optical Network Terminal management and control interface (OMCI) message.

15. A passive optical network (PON) system, comprising at least one passive optical network (PON) component and an optical line termination (OLT);

wherein the PON component is configured to generate a first passive optical network (PON) protocol message, wherein the first PON protocol message comprises a first action indication indicating that the PON user terminal intends to exercise a first power supply mode that is a power-saving mode, wherein the first power supply mode is operated at lower power than a power provided in a second power supply mode, wherein in the second power supply mode, a power supply is provided to the PON user terminal such that the PON user terminal can provide service data from an optical line termination (OLT) to a user and communicate with the OLT via an established upstream connection;

send the first PON protocol message; and

enter the PON user terminal in the first power supply mode, wherein in the first power supply mode, both upstream communication and downstream communication with the OLT are disabled to break, while retaining the ability to switch from the first power supply mode to the second power supply mode;

wherein the OLT is configured to receive the first passive optical network (PON) protocol message.

16. The PON system of claim 15, wherein the PON component is configured to send a second PON protocol message from the PON user terminal in the first power supply mode, wherein the second PON protocol message comprises a second action indication indicating that the PON user terminal intends to be operated in the second power supply mode.

17. The PON system of claim 15, wherein in the first power supply mode, an upstream PON interface unit (PONIU) of the PON component is turned off and the established upstream connection is disconnected, and the PON component is further configured to detect whether the upstream PONIU is reactivated and an upstream connection with the OLT is reestablished.
