Passive optical network user terminal and method of power supply control and power supply state reporting for the same
First Claim
1. A passive optical network (PON) component, comprising:
- a plurality of service processing units configured to process service data;
a service state checking unit configured to monitor usage of the plurality of service processing units;
a power supply control unit configured to activate an energy-saving power supply mode on at least one service processing unit when the at least one service processing unit is not in use;
wherein the PON component sends an alert message to an optical line terminal (OLT) when the at least one service processing unit of the PON component enters an energy-saving power supply mode, the alert message comprises an identifier of the PON component and an action identifier that indicates an operation of entering the energy-saving power supply mode.

Abstract
The present disclosure discloses a passive optical network (PON) user terminal comprising a passive optical network interface unit (PONIU) having access to a PON system, a service data distribution unit (SDDU) connected to the PONIU for distributing service data, a plurality of service processing units (SPUs) for receiving and accordingly processing the service data distributed by the SDDU, a power source for providing power to the above units, and a power supply control unit (PSCU) for controlling the activating/deactivating of the energy-saving power supply to the SPUs, the SDDU, and the PONIU. 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.

10. A method comprising:
-
activating an energy-saving power supply mode on an optical network unit (ONU) in responsive to detection of inactivity at a service processing unit in the ONU; and sending an alert message to an optical line terminal (OLT) to alert the OLT of a power supply state change in the ONU when the ONU enter the energy-saving power supply mode; wherein the alert message comprises an identifier of the ONU that enters the energy-saving power supply mode, and an action identifier that indicates an operation of entering the energy-saving power supply mode. - View Dependent Claims (11, 12, 13)
