    • A mobile communication system has a plurality of nodes, hierarchically connected to each other, including a source base station and a target base station. A U-plane management station includes detecting unit detecting a handover for the mobile terminal, and a Bi-casting unit redundantly transmitting, when detecting the handover for the mobile terminal, the same user data addressed to the mobile terminal toward both of the source base station and the target base station. The target base station includes a retaining unit receiving the user data addressed to the mobile terminal, which is transmitted by the U-plane management station, and retaining the user data, and a wireless transmitting unit wirelessly transmitting, when the mobile terminal is wirelessly connected after moving, the user data requested by the mobile terminal in the user data retained by the retaining unit and addressed to the mobile terminal.

    • In a network system including base stations accommodated in a mobile phone network through an IP network, when a mobile phone terminal as a calling terminal makes a calling request and the calling request from the calling terminal is sent through a source base station to the mobile phone network and then from the mobile phone network through a destination base station to a mobile phone terminal as a called terminal, it is judged whether the source base station and the destination base station are both connected to the mobile phone network through the same IP network, and when the source base station and the destination base station are both connected to the mobile phone network through the same IP network, a data transmission path is established between the calling terminal and the called terminal that directly connects the source base station and the destination base station through the same IP network and without via the mobile phone network.
    • 在包括通过IP网络容纳在移动电话网络中的基站的网络系统中,当作为主叫终端的移动电话终端进行呼叫请求时,来自主叫终端的呼叫请求通过源基站发送到移动电话 网络,然后从移动电话网络通过目的地基站到作为被叫终端的移动电话终端,判断源基站和目的地基站是否都通过相同的IP网络连接到移动电话网络, 并且当源基站和目的地基站通过相同的IP网络连接到移动电话网络时,在主叫终端和被叫终端之间建立直接连接源基站和目的地基站的数据传输路径 站通过相同的IP网络,无需通过手机网络。
