摘要:
A relay station includes a signal generation unit configured to generate a signal in the relay station and a receiving unit configured to receive a signal from a first communication station. The relay station further includes a signal generating node identifying unit configured to identify whether a signal to be transmitted to a second communication station is a received signal received from the first communication station or a generated signal generated by the signal generation unit. The relay station further includes a signal transmission unit configured to transmit both or one of the received signal and the generated signal associated with a radio bearer to the second communication station.

A mobile communication method according to the present invention comprising a step in which the mobile switching center MME transmits Attach Accept including the KeNB to the relay node RN in response to the received Attach Request, a step in which the radio base station DeNB generates the K_RRCint, the K_RRCenc, and the K_UPenc based on the received KeNB, and notifies the relay node RN of only the K_RRCint and the K_RRCenc, and a step in which the relay node RN saves the notified K_RRCint and K_RRCenc.
摘要:
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 perform a handover process between a state in which a radio bearer is set with the relay node so as to communicate via the relay node and the radio base station, and a state in which a radio bearer is set with the radio base station so as to communicate via the radio base station. The handover process is configured such that a data signal is transferred via the 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 second relay node connected via a radio bearer. The second relay node and a radio base station are connected via a radio bearer. A mobile station is configured to perform a handover process between the state in which a radio bearer is set with the first relay node in order to communicate via the first relay node, the second relay node, and the radio base station, and the state in which a radio bearer is set with the second relay node in order to communicate via the second relay node and 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 the radio bearer between the first relay node and the second relay node.
