Claim Text:
1. A radio base station, comprising: a controller that generates a message comprising an identification information of the radio base station and an information on an environment around the radio base station; and a transmitter that transmits the generated message to a Home Evolved Node B Gateway (HeNB-GW), wherein the information on the environment around the radio base station includes identification information of a HeNB-GW most recently connected to the radio base station, wherein the identification information and the information on the environment around the radio base station are used by the HeNB-GW for a determination of whether or not the radio base station is operational, wherein when it is determined that the radio base station is operational, the identification information of the radio base station and information on an environment around the radio base station is forwarded from the HeNB-GW to the Mobility Management Entity (MME) to carry on a normal processing for the radio base station, and wherein when it is determined that that base station is non-operational, a failure message is transmitted from the HeNB-GW to the radio base station to disconnect a connection between the radio base station and the HeNB-GW.
