A radio base station includes a mobile communication system, a relay node and a radio base station connected via a radio bearer. A mobile station is configured to conduct a handover process between the state in which a radio bearer is set with the relay node in order to communicate via the relay node and the radio base station, and the state in which a radio bearer is set with the radio base station in order to communicate via the radio base station. The mobile station is configured such that during the handover process, control signals involved in the handover process are sent and received via a radio bearer between the relay node and the radio base station.

A radio base station includes a mobile communication system, a first relay node and a first radio base station connected via a radio bearer, a second relay node, and a second radio base station connected via a radio bearer. The first radio base station and the second radio base station are connected via a bearer, in which a mobile station is configured so as to conduct a handover process between a first and second state. In the first state a radio bearer is established with the first relay node in order to communicate. In the second state a radio bearer is established with the second relay node in order to communicate. The mobile station is configured such that in the handover process, control signals are transmitted and received via the radio bearer between the first relay node, first radio base station, second radio base station, and second relay node.

A radio base station includes a mobile communication system configured to transmit and receive a data signal between a mobile station and a gateway device via a relay node and a radio base station. The mobile communication system is configured such that the radio bearer for the mobile station is set between the mobile station and the relay node. The radio bearer for the relay node is set between the relay node and the radio base station. A network bearer for the mobile station is set between the relay node and the gateway device. The network bearer for a plurality of mobile stations is multiplexed in the radio bearer for the relay node, and a data signal is transmitted and received between the mobile station and the gateway device via the radio bearer for the mobile station and the network bearer for the mobile station.
