Control device, handover control method and mobile communication system |
摘要 |
<p>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.
