    • A mobility management system and method is provided for efficiently support mobility to an IPv6 based LoWpan. The mobility management method for Internet Protocol version 6 (IPv6) based personal area network (PAN) moving with a mobile router according to the present invention includes detecting, at a mobile terminal, movement of the mobile router; determining whether the movement is an intra-network movement or an inter-network movement, transmitting, when the movement is an intra-network movement, a neighbor discovery request message to a gateway of a currently attached network and receiving a neighbor discovery response message containing a temporary address transmitted by the gateway in response to the neighbor discovery request message. When the movement is an inter-network movement, the gateway receives the binding acknowledgement message from a home agent and establishes a bidirectional tunnel with the home agent.
    • 提供了一种移动性管理系统和方法,用于有效地支持基于IPv6的LoWpan的移动性。 根据本发明的用移动路由器移动的基于互联网协议版本6(IPv6)的个人区域网(PAN)的移动性管理方法包括在移动终端处检测移动路由器的移动; 确定移动是网络内移动还是网络间移动,当移动是网络内移动时,向当前附接网络的网关发送邻居发现请求消息,并且接收包含以下内容的邻居发现响应消息: 由所述网关响应于所述邻居发现请求消息而发送的临时地址。 当移动是网络间移动时,网关从归属代理接收绑定确认消息,并与归属代理建立双向隧道。
