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 power source comprising a main power source and a backup power source, wherein the main power source is provided by a user premises and the backup power source comprises a battery installed in the PON component;
a plurality of service processing units (SPUs) configured to process service data;
a service state checking unit that monitors usage of the plurality of SPUs;
a power supply control unit (PSCU) in communication with the power source and the plurality of SPUs, wherein the PSCU is configured to control the power supplied from the power source to the plurality of SPUs, and wherein the PSCU activates an energy-saving power supply mode to at least one of the SPUs when the at least one SPU is not in use and the main power source is functional, and deactivates the energy-saving power supply to the at least one SPU when the at least one SPU is needed;
a PON interface unit (PONIU) configured to receive the service data from a PON system; and
a service data distribution unit (SDDU) configured to receive the service data from the PONIU and distribute a different type of service data to each of the plurality of SPUs.

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.

6. A passive optical network (PON) component comprising a processor configured to:
-
provide backup power to a plurality of service processing units (SPUs) within the PON component when a main power source is disconnected, wherein the backup power comprises a battery installed on the PON component; monitor the usage of the plurality of SPUs; responsive to detecting inactivity of all of the SPUs, activate an energy-saving power supply mode by a power supply control unit (PSCU) to the plurality of SPUs, a passive optical network interface unit (PONIU), and a service data distribution unit (SDDU); and subsequently deactivate the energy-saving power supply mode to at least one of the SPUs, the PONIU, and the SDDU when at least one of the SPUs is needed, wherein the PON component is an optical network unit (ONU) comprising the PONIU, the SDDU, the plurality of SPUs, and the PSCU, and wherein the plurality of SPUs comprises a video SPU, a voice SPU, and a data access SPU. - View Dependent Claims (7, 8)

9. A method for reporting a power supply state in a passive optical network (PON) optical network unit (ONU), comprising:
-
sending a message to an optical line terminal (OLT) to alert the OLT of the power supply state change in the PON ONU, wherein a main power supply of the PON ONU is functional, and wherein the message identifies which of a plurality of service processing units within the PON ONU had a power supply state change. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16, 19)
