    • An object of the present invention is to avoid packet loss and implement a seamless handover by minimizing the handover latency when a handover is implemented by a multihomed moving network (MN) or a mobile host (MH). The present invention is a mobile communication system that is constituted comprising an MN, a plurality of AI each constituting an interface for the connection to a core network at the MN, and a control device (MMF), wherein the MMF dynamically changes the AI adopted as the connection interface when a predetermined condition is satisfied on the basis of the connection status to the core network at each AI or the prediction information for a subsequent handover. In so doing, the control device continues the transmission and receipt of data with respect to an appropriate AI capable of maintaining a predetermined communication quality, and maintains the connection to the core network of another AI while causing this AI to enter a closed state in which the transmission and receipt of data is disabled.
    • 本发明的目的是为了避免分组丢失,并且通过在多宿主移动网络(MN)或移动主机(MH))实现切换时最小化切换等待时间来实现无缝切换。 本发明是一种移动通信系统,其包括MN,多个AI,每个AI构成用于连接到MN处的核心网络的接口和控制设备(MMF),其中MMF动态地改变所采用的AI 作为连接接口,当根据在每个AI处的核心网络的连接状态或者随后的切换的预测信息来满足预定条件时。 在这样做时,控制装置继续相对于能够保持预定通信质量的适当AI的数据的发送和接收,并且保持与另一AI的核心网络的连接,同时使该AI进入关闭状态,其中 数据的传输和接收被禁用。
