    • A method of operating a communication system is disclosed. A first communication session between a first base station and a mobile station is established. A service session between a first access network and the mobile station is established. When the mobile station moves to the service area of a new base station, a second communication session between a second base station and the mobile station is established. A distance between the first base station and the second base station is determined. If the distance exceeds a criteria, the service session is handed off a second access network. The criteria, which must be greater than zero, corresponds to the number of base station service areas separating the first base station and the second base station.
    • 公开了一种操作通信系统的方法。 建立第一基站和移动台之间的第一通信会话。 建立第一接入网与移动台之间的业务会话。 当移动站移动到新基站的服务区时,建立第二基站与移动台之间的第二通信会话。 确定第一基站和第二基站之间的距离。 如果该距离超过一个标准,则会将第二个接入网络切换成业务会话。 必须大于零的标准对应于分离第一基站和第二基站的基站服务区域的数量。

    • The pump clutch is a device which transfers energy from its input shaft to the output shaft where a hydraulic gear pump is provided to enable the circulation of oil inside. The clutch input shaft is connected to the pressure production system; thus, the energy it requires to circulate the oil is provided. The amount of engagement between the clutch output shaft and the clutch input shaft is determined by the amount of oil circulating in the system. In turn, the amount of oil in the device is controlled by the control tap. With the clutch output shaft stabilized on the surface, we can control the circulation of the oil in the system with the control tap and the energy in the input shaft is thus transferred onto the stabilized surface through the output shaft thereby halting the rotation of the input shaft.
    • 泵离合器是将能量从其输入轴传递到输出轴的装置,其中设置有液压齿轮泵以使其内部的油循环。 离合器输入轴连接到压力生产系统; 因此,提供了循环油所需的能量。 离合器输出轴和离合器输入轴之间的接合量由系统中循环的油量确定。 反过来,设备中的油量由控制龙头控制。 当离合器输出轴稳定在表面上时,我们可以通过控制龙头来控制系统中的油的循环,并且输入轴中的能量通过输出轴转移到稳定的表面上,从而停止输入的旋转 轴。
