Abstract
The present disclosure relates to message transmission methods in a PON system. One example method includes sending, by an optical line terminal (OLT), a first message to an unregistered optical network unit (ONU), where the first message includes at least one piece of indication message, and one piece of indication message of the at least one piece of indication message indicates a first power range and a first time range associated with the first power range, and receiving, by the OLT in the first time range, a registration message sent by the ONU, where a downstream receive power of the ONU falls within the first power range.
Claims23
A message transmission method, comprising:
- sending, by an optical line terminal (OLT), a first message to an optical network unit (ONU), wherein the first message comprises at least one piece of indication message, and wherein one piece of indication message of the at least one piece of indication message indicates a first power range and a first time range to indicate the ONU whose downlink receive power falls within the first power range to send a registration message in the first time range;
- and
- receiving, by the OLT, the registration message.
A message transmission method, comprising:
- receiving, by an unregistered optical network unit (ONU), a first message sent by an optical line terminal (OLT), wherein the first message comprises at least one piece of indication message, and wherein one piece of indication message of the at least one niece of indication message indicates a first power range and a first time range;
- and
- sending, by the ONU, a registration message to the OLT in the first time range indicated in the one niece of indication message, wherein a downstream receive power of the ONU falls within the first power range indicated in the one piece of indication message.
An optical line terminal (OLT, comprising:
- a transceiver, the transceiver configured to send a first message to an optical network unit (ONU), wherein the first message comprises at least one piece of indication message, and wherein one piece of indication message of the at least one niece of indication message indicates a first power range and a first time range to indicate the ONU whose downlink receive power falls within the first power range to send a registration message in the first time range;
- and
- at least one processor, the at least one processor configured to instruct the transceiver to receive the registration message.
An optical network unit (ONU), comprising:
- a transceiver, the transceiver configured to receive a first message sent by an optical line terminal (OLT), wherein the first message comprises at least one piece of indication message, and wherein one piece of indication message of the at least one piece of indication message indicates a first power range and a first time range;
- and
- at least one processor, the at least one processor configured to determine whether a downstream receive power of the ONU falls within the first power range indicated in the one piece of indication message;
- wherein the transceiver is further configured to send a registration message to the OLT in the first time range indicated in the one piece of indication message, wherein a downstream receive power of the ONU falls within the first power range indicated in the one piece of indication message.
A message structure, comprising:
- at least one piece of indication message, wherein one piece of indication message of the at least one piece of indication message indicates a first power range and a first time range to indicate an optical network unit (ONU) whose downlink receive power falls within the first power range to send a registration message in the first time range.
