摘要： A CU (Central Unit) executes scheduling for allocating radio resources of RRUs (Remote Radio Units) to radio transmission of downlink data while broadcasting, to DMs (Data Managers) via MFH, downlink data from MBH. Each DM selects, based on an allocation result obtained by scheduling, the downlink data of an RRU (Remote Radio Unit) corresponding to the self DM from the accumulated downlink data from the CU, and transfers the selected downlink data to the corresponding RRU while discarding the downlink data of other RRUs. Based on the allocation result, each RRU performs radio transmission of the downlink data from the DM to a corresponding UE (User Equipment) using the designated radio resource. This makes it possible to efficiently transfer the downlink data from the CU to each RRU via the MFH constructed by a TDM system represented by TDM-PON.

摘要： An upstream allocation circuit (14) and a downstream allocation circuit (15) are provided in an OLT (1). For example, a superimposed frame obtained by bundling upstream frames (upstream control frames + upstream data frames) from all ONUs is input to the upstream allocation circuit (14) via a frame reproduction circuit (12-1). The superimposed frame may be generated at the stage of optical signals or generated after converting optical signals into electrical signals. The upstream allocation circuit (14) allocates each of the upstream control frames bundled into the superimposed frame to a predetermined PON control circuit (13) based on information (PON port number or LLID) added to the frames. The downstream allocation circuit (15) allocates, to a preset frame reproduction circuit (12), each downstream control frames output from the PON control circuits (13).

摘要： An OLT (1) is formed by N optical transceivers (11), one PON control circuit (12), and one selection and distribution circuit (13). An optical transceiver selection control signal (SC) is transferred from the PON control circuit (12) to the selection and distribution circuit (13). The optical transceiver selection control signal (SC) indicates the timing of a discovery window, the timing of a grant, and a logical link identification number of a registered ONU assigned to the grant (a logical link identification number for a logical link with the registered ONU). The selection and distribution circuit (13) selects one optical transceiver (11-s (s is an integer falling within a range of 0 to N-1)) from the optical transceivers (11-0 to 11-N -1 ) based on the optical transceiver selection control signal (SC) from the PON control circuit (12).

摘要： A convergence pattern selection unit (10A) sequentially generates a plurality of different patterns based on designated initial conditions, selects, as a convergence pattern, a pattern in which evaluation value has converged to an extreme value, and repeatedly executes selection of the convergence pattern by changing the initial conditions every time the convergence pattern is selected. A transmission pattern determination unit (10B) selects, as an optimum transmission pattern, one of the convergence patterns obtained by the convergence pattern selection unit (10A), which has the highest evaluation value. This allows searches for an optimum transmission pattern having a better evaluation value.

摘要： A selection and distribution circuit (13) is provided between N optical transceivers (11) and one PON control circuit (12). The selection and distribution circuit (13) selects the optical transceiver (11) corresponding to an upstream frame that time-divisionally arrives, thereby transferring the upstream frame opto-electrically converted by the transceiver (11) to the PON control circuit (12) and distributing a downstream frame from the PON control circuit (12) to each optical transceiver (11). A power supply control circuit (23) stops power supply to at least one of one of optical transceivers (11) that are not used to transfer the frame of the optical transceivers (11) and a circuit that is not used to transfer the frame in the selection and distribution circuit (13). This can reduce the system cost per ONU in the optical transmission system.
