    摘要： In the method of handover control, when a mobile station recognizes that the mobile station has moved to an overlapping area, the mobile station notifies this fact to a network side and in response the network side sets up only a communication channel between a handover target base station and an exchange station for controlling that handover target base station, without setting up a radio channel between the handover target base station and the mobile station, while continuing the communication by not releasing the communication channel between the currently located base station and the exchange station and the radio channel between the currently located base station and the mobile station, so that it becomes possible to reduce a transmission control load for transmission between the base station and the exchange station as well as a control load for controlling the exchange station itself.

    摘要翻译： 在切换控制的方法中，当移动台识别出移动台已经移动到重叠区域时，移动台向网络侧通知该事实，作为响应，网络侧仅设置切换对象基站 站和用于控制切换目标基站的交换站，而不在切换目标基站和移动站之间建立无线电信道，同时通过不释放当前所在的基站和交换站之间的通信信道来继续通信 以及当前所在的基站与移动台之间的无线电信道，从而可以减少基站与交换站之间的传输的传输控制负载以及用于控制交换站本身的控制负载。

    摘要： When a network pages the temporary user mobile identifier of a mobile station, the mobile station sends a response to the network. Next, the network checks the authenticity of the user using a ciphering key, corresponding to the temporary user mobile identifier and a random number. If the temporary user mobile identifier is authenticated, a normal incoming call acceptance procedure is executed. If the mobile station is authenticated although the temporary user mobile identifier is wrong, the network reassigns a new temporary user mobile identifier to the mobile station and stops the current communication. In communication, the network and the mobile station mutually notify encipherment-onset time and negotiate about encipherment manner with each other. In addition, diversity handover is commenced upon a call attempt. Furthermore, if a branch replacement is necessary, the current branch is replaced by new branches capable of executing the diversity handover. Additionally, when a new call occurs to or from the mobile station capable of treating a plurality of calls simultaneously, the mobile station uses the same branch structure and the same communication frequency band for all of calls. Additionally, when a new call occurs to or from the mobile station capable of treating a plurality of calls simultaneously, a branch structure and a communication frequency band, which can continue all of the calls, are selected and used. Therefore, the mobile communications system is suitable for transmission of various sorts of data in accordance with the development of multimedia.
