A radio base station managing a handover source cell decides a method for achieving a handover in consideration of CSG-ID and Access Mode of a handover destination cell. A mobile communication method comprises: a step of notifying, by a radio base station HeNB#1, a radio base station HeNB#2 of CSG-ID and Access Mode of cell subordinate to a radio base station HeNB#1, when establishing an X2 connection with the radio base stations HeNB#2; the radio base station HeNB#2 managing the CSG-ID and the Access Mode of the cell subordinate to the radio base station HeNB#1; a step of deciding the method for performing the handover of the mobile station UE from the cell subordinate to the radio base station HeNB#2 to the cell subordinate to the radio base station HeNB#1 on the basis of the managed CSG-ID and Access Mode of the cell subordinate to the radio base station HeNB#1.

Interference to a reception circuit of a relay node itself is reduced, which occurs when transmission-and-reception process in a Un radio bearer and transmission-and-reception process in a Uu radio bearer are simultaneously performed. A mobile communication method according to the present invention includes a step of determining, by a relay node RN, whether it is necessary to perform the scheduling of a second timing such that the second timing does not overlap a first timing in a time direction, based on a first operating frequency f1 used in a radio zone between the relay node RN and a mobile station UE and a second operating frequency f2 used in a radio zone between a radio base station DeNB and the relay node RN, and a step of notifying, by the relay node RN, the radio base station DeNB of the determination result.
摘要:
A radio base station includes a mobile communication system, a first relay node and a radio base station connected via a radio bearer, a second relay node and a radio base station connected via a radio bearer, and a mobile station configured 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 via the first relay node and the radio base station. In the second state a radio bearer is established 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 control signals are transmitted and received via the radio bearer between the first relay node and the radio base station, via the radio bearer between the second relay node and the radio base station.
