Title:
OPTICAL COMMUNICATION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2019/026281
Kind Code:
A1
Abstract:
In an optical communication system pertaining to the present invention, an ONU 5 receives a SUBFRAME.indication frame from a slave station device 2. A time detection unit 24 detects a subframe start time for the frame on the basis of a frame reception trigger indicating the reception of the frame. A frame generation unit 25 generates a notification frame for notifying an OLT 4 of the subframe start time. On the basis of the notification frame, the OLT 4 performs optical uplink scheduling by accurately matching, with optical uplink scheduling information in a PON, radio uplink scheduling information for each UE 3 and slave station device 2 managed by a master station device 1 and notifies the ONU 5.
