摘要： 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.

摘要： 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.
