    • 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.
    • 为了减少广播“测量子帧模式”的小区的数量,在本发明的移动通信方法中,无线基站eNB#2在无线基站eNB中广播小区#2中的广播信息 #1在小区#1中广播“测量子帧模式”。 在空闲模式下的移动台UE接收在小区#1中广播的“测量子帧模式”,以便当移动台UE检测到时,基于设置广播信息进行基于“测量子帧模式”的“测量处理” 在小区#2中广播,在相邻小区中广播“测量子帧模式”。

    • A surface acoustic wave element has a small energy loss and when it is used in a filter device, suppresses a spurious component occurring near the resonant frequency of a principal response and improves the frequency characteristic near the pass band of the filter device. The surface acoustic wave element includes a piezoelectric substrate, a comb-shaped electrode, and an insulating film. The comb-shaped electrode is disposed on the piezoelectric substrate. The insulating film is disposed so as to cover the piezoelectric substrate and the comb-shaped electrode. Where λ is the wavelength of an elastic wave that propagates in the piezoelectric substrate and h is the difference between the maximum and minimum values of a thickness dimension from the top surface of the piezoelectric substrate to the top surface of the insulating film, 0.01≦h/λ≦0.03 is satisfied.
