    • 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。

    • A mobility header compression method and system for an IPv6-based LoWPAN is provided for supporting IPv6 mobility to the IPv6-based LoWPAN checks a packet carrying data and a first and a second headers containing transmission information about the data to determine whether the second header contains a compressed Internet Protocol version 6 (IPv6) information. When the second header contains a compressed IPv6 information, ands followed by a mobility header, a mobility support-indicative field of the first header is set to indicate that the second header is followed by the mobility header and the rest of the fields of the second header are compressed except for the mobility header-indicative field. A mobility information-indicative field of the mobility header is set to indicate inclusion of mobility information; and the rest of the fields of the mobility header are compressed except for the mobility information-indicative field.
    • 提供了一种用于基于IPv6的LoWPAN的移动性报头压缩方法和系统,用于支持基于IPv6的LoWPAN的IPv6移动性检查携带数据的分组,以及包含关于数据的传输信息的第一和第二报头,以确定第二报头是否包含 压缩的Internet协议版本6(IPv6)信息。 当第二报头包含压缩的IPv6信息,随后是移动性报头时,第一报头的移动性支持指示字段被设置为指示第二报头跟随移动性报头,并且第二报头的其余部分 除了移动性报头指示字段之外,报头被压缩。 移动性报头的移动信息指示字段被设置为指示包括移动性信息; 并且移动性报头的其余部分被压缩,除了移动信息指示字段之外。
