To control a radio link capacity in a backhaul link optimally, and to enhance a throughput in an access link, in the radio communications system using the relay transmission technology. A relay frequency allocation method according to the present invention includes: determining whether or not carrier aggregation is to be applied in a backhaul link from a radio base station apparatus to a mobile terminal device under the command of the radio base station apparatus, and/or an access link from a radio relay station apparatus to a mobile terminal device under the command of the radio relay station apparatus; allocating a frequency band for transmitting a downlink signal in the backhaul link and/or the access link, when applying the carrier aggregation; and transmitting the downlink signal with the allocated frequency band in the backhaul link and/or the access link.

A mobile station UE according to the present invention includes a determination unit 13 configured to determine whether the mobile station UE is a registered mobile station in a radio base station HeNB2 based on broadcast information transmitted by the radio base station HeNB2 when the mobile station UE uses a cell subordinate to a radio base station eNB as a serving cell, and a measurement report transmission unit 14 configured to transmit a measurement report including predetermination information indicating the determination result to the radio base station eNB.
摘要:
A mobile communication method according to the present invention comprising the relay node RN configured to the method comprising a step in which the relay node RN transmits the “X2-AP (UE): Handover Request” to the radio base station DeNB #2, a step in which the radio base station DeNB #2 acquires the K_eNB* and the MAC from the radio base station DeNB #1, a step in which the radio base station DeNB #2 generates the KeNB based on the acquired K_eNB* and the MAC, and a step in which the radio base station DeNB #2 generates the K_RRCint, the K_RRCenc, and the K_UPenc based on the generated KeNB.
摘要:
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.
摘要:
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.
