1. A method, comprising:
- 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, 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 PON protocol message; and
activating the first power supply mode in which a plurality of units of the PON user terminal comprising an optical-electrical conversion module, a PON protocol processing module and a service processing unit (SPU) are disabled to break both upstream communication and downstream communication with the OLT, while an activity detection operation on the SPU remains active.

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.
