Abstract
Provided is a network management device capable of suppressing interference of a preamble between cells while securing a predetermined resource. An FGW (500) as the device is a network management device for managing a plurality of base station devices each of which perform communication with communication terminal devices by the SC-FDMA method, wherein the FGW (500) is provided with a parameter determination unit (530) for determining parameters related to an uplink preamble with respect to at least one among the plurality of base station devices, and a parameter notification unit (540) for sending notifications of the determined parameters to the base station devices for which the parameters have been determined; wherein the parameter determination unit (530) determines the parameters so that transmitted sequences of the preamble do not overlap between at least two of the plurality of base station devices.
