COMMUNICATION SYSTEM, FEMTO CELL BASE STATION, AND COMMUNICATION METHOD

摘要

A femto-cell base station acquires an IP address of a CS-dedicated relay device from a first management device, connects to the CS-dedicated relay device based on the acquired IP address of the CS-dedicated relay device, and establishes a first IPsec Tunnel between the femto-cell base station and the CS-dedicated relay device. The fenito-cell base station also acquires an IP address of a PS-dedicated relay device from a second management device through the first IPsec Tunnel, connects to the PS-dedicated relay device based on the acquired IP address of the PS-dedicated relay device, and establishes a second IPsec Tunnel between the femto-cell base station and the PS-dedicated relay device.
