    Abstract: In the case of radio base stations of different kinds, a synchronization in a radio section cannot be established so that the efficiently effective use of electric waves cannot be retained. According to the invention, therefore, there is provided a TDMA type mobile communication system 100 comprising: a plurality of radio base stations of different system kinds (i.e., a general type radio base station 1, an IP connection type radio base station 10 and a main digital cordless phone 2); mobile phones 5A and 5B wirelessly connected with the plural radio base stations; and a private branch exchange 4 wired with the radio base stations. The radio base station receives, when a synchronized operation mode is decided, a frame signal containing a control CH signal, from a reference radio base station (i.e., a reference station); and times the transmission of the frame signal of a local station to the transmission position of the control CH signal in the frame signal, thereby to establish a frame synchronization in a radio section between own station and the reference radio base station.

    Abstract translation: 在不同种类的无线电基站的情况下，无法建立无线电部分中的同步，从而不能保持电波的有效利用。 因此，根据本发明，提供了一种TDMA型移动通信系统100，包括：多个不同系统种类的无线基站（即通用型无线基站1，IP连接型无线基站10和 主要数字无绳电话2）; 与多个无线电基站无线连接的移动电话5A和5B; 以及与无线电基站有线的专用小区交换机4。 无线电基站从参考无线电基站（即参考站）接收同步操作模式时包含控制CH信号的帧信号; 并将本地站的帧信号传输到帧信号中的控制CH信号的发送位置，从而在本站与参考无线基站之间的无线部分建立帧同步。
