Abstract
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.

8. A mobile communication method, comprising a step of deciding, by a second radio base station, a method for performing a handover of a mobile station from a cell subordinate to the second radio base station to a cell subordinate to a first radio base station, wherein
in the step, the second radio base station considers an X2 handover as the method for performing the handover, when registered-group identification information of the cell subordinate to the first radio base station is the same as registered-group identification information of the cell subordinate to the second radio base station and when an access mode of the cell subordinate to the first radio base station is not “ - Open”
