Abstract: An OSS generates second identification information from first identification information, and generates setting information of a low power base station device based on the second identification information while reflecting position information. When verification of the first identification information is successful, the OSS transmits third identification information of a security GW and fourth identification information of an EMS to the low power base station device. The EMS receives a power on notification from the low power base station device via an IPsec tunnel established at the security GW. The OSS identifies the second identification information from the first identification information included in the power on notification, and writes the setting information identified from the second identification information to the low power base station device.
