Method for awaking optical network unit in passive optical network, device, and system

A method for awaking an optical network unit (ONU) in a passive optical network (PON) wherein the method comprises:

• receiving, by an ONU, a service packet when the ONU is in an energy-saving mode, wherein the service packet carries a packet feature, and the packet feature indicates a service type of the service packet;
• detecting, by the ONU, the packet feature of the service packet;
• and
• when the packet feature is a preset packet feature of needing to awake the ONU, awaking the ONU from the energy-saving mode.

An optical line terminal (OLT), wherein the OLT comprises:

• a receiving unit, configured to receive a service packet corresponding to an Optical Network Unit (ONU) in an energy-saving mode, wherein the service packet carries a packet feature, and the packet feature indicates a service type of the service packet;
• a detection unit, configured to detect the packet feature of the service packet;
• and
• an awaking unit, configured to:
• when the packet feature of the service packet is a preset packet feature of needing to awake the ONU, awake, by the OLT, the ONU in the energy-saving mode.

An optical network unit (ONU), wherein the ONU comprises:

• a receiving unit, configured to receive a service packet, wherein the service packet carries a packet feature, and the packet feature indicates a service type of the service packet;
• a detection unit, configured to detect the packet feature of the service packet;
• and
• an awaking unit, configured to:
• when the packet feature is a preset packet feature of needing to awake the ONU, awake the ONU from the energy-saving mode.

A passive optical network (PON) system, wherein the system comprises an Optical Line Terminal (OLT) and an Optical Network Unit (ONU), wherein

• the OLT is configured to receive a service packet corresponding to the ONU in an energy-saving mode, wherein the service packet carries a packet feature, and the packet feature indicates a service type of the service packet;
• and the OLT is configured to:
• detect the packet feature of the service packet, and when the packet feature of the service packet is a preset packet feature of needing to awake the ONU, awake the ONU in the energy-saving mode;
• and
• the ONU is configured to be awoken from the energy-saving mode.

A passive optical network (PON) system, wherein the system comprises an Optical Line Terminal (OLT) and an Optical Network Unit (ONU), and the ONU is in an energy-saving mode, wherein

• the ONU is configured to receive a service packet, wherein the service packet carries a packet feature, and the packet feature indicates a service type of the service packet;
• and the ONU is configured to detect the packet feature of the service packet, and when the packet feature of the service packet is a preset packet feature of needing to awake the ONU, send an awaking instruction request to the OLT;
• and
• the OLT is configured to:
• receive an awaking instruction request of the ONU, and instruct the ONU to be awoken from the energy-saving mode.
