Kind Code:
B2
Abstract:
To delivery an upstream signal from User Equipment to an upper of an Optical Line Terminal with a short delay in a system in which the Optical Line Terminal and an Optical Network Unit are connected and the Optical Network Unit and a wireless channel terminal device are connected.SOLUTION: An OLT (Optical Line Terminal) comprises: a transmission permission section that in response to a transmission request transmitted by UE (User Equipment), sets ONU (Optical Network Unit) transmission time in a first time form in synchronization with a time distribution network; and a time form conversion section that converts the ONU transmission time in the first time form to one in a second time form capable of being interpreted by an ONU. An AP comprises: a time form conversion section that converts the transmission time in the second time form, to which the OLT has converted, to one in the first time form; and a transmission permission section that on the basis of converted transmission time in the first time form, acquires UE transmission time in the first time form. The AP time form conversion section converts the UE transmission time, in the first form, acquired by the AP transmission permission section to one in a third time form and transmits information indicating the converted UE transmission time in the third time form to the UE.SELECTED DRAWING: Figure 2
