Mobile communication method, mobile communication system, and information transfer device

A mobile communication system comprising:

• a network device;
• and
• a plurality of information transfer devices, wherein:
• the network device is configured to notify one of the information transfer devices of identification information on a radio base station, the one information transfer device corresponding to an inputted installation location of the radio base station;
• each of the information transfer devices is configured to manage the notified identification information on the radio base station;
• in a case where the radio base station transmits, at the time of installation or moving, an installation signal to an information transfer device to which the radio base station is connected, the information transfer device to which the radio base station is connected is configured to transfer the installation signal to the network device if the identification information on the radio base station included in the received installation signal is managed by the information transfer device;
• and
• in a case where the radio base station transmits, at the time of installation or moving, an installation signal to an information transfer device to which the radio base station is connected, the information transfer device to which the radio base station is connected is configured to discard the installation signal without transferring the installation signal to the network device if the identification information on the radio base station included in the received installation signal is not managed by the information transfer device,
• wherein the information transfer device to which the radio base station is connected instructs the radio base station to notify the network device of an installation location of the radio base station, if the information transfer device does not manage the identification information on the radio base station included in the received installation signal.

An information transfer device connected to a network device, comprising:

• a managing unit configured to manage identification information on a radio base station notified by the network device;
• and
• a transfer unit configured to transfer, to the network device, an installation signal transmitted by a radio base station at the time of installation or moving, if the identification information on the radio base station included in the installation signal is managed, wherein
• the transfer unit is configured to discard an installation signal transmitted by the radio base station at the time of installation or moving, without transferring the installation signal to the network device, if identification information on a radio base station included in the installation signal is not managed,
• wherein the transfer unit instructs the radio base station to notify the network device of an installation location of the radio base station if the identification information on the radio base station included in the installation signal is not managed.
