摘要： To reduce the number of cells in which a “Measurement Subframe Pattern” is broadcasted, in the mobile communication method according to the present invention, a radio base station eNB#2 broadcasts setting broadcast information in a cell #2 when a radio base station eNB#1 broadcasts a “Measurement Subframe Pattern” in a cell #1. A MOBILE STATION UE in Idle mode receives the “Measurement Subframe Pattern” broadcasted in the cell #1 in order to perform a “Measurement process” based on the “Measurement Subframe Pattern” when the MOBILE STATION UE detects, based on the setting broadcast information broadcasted in the cell #2, that the “Measurement Subframe Pattern” is broadcasted in a neighbor cell.
