摘要： A plurality of nodes each including a transmitter, a receiver, and a controller is linked together via a network. The transmitter of a transmission node using multiple wireless interfaces sends a beacon message sending its own node identifier and wireless interfaces to at least one reception node, which in turn sends back a response message sending its own node identifier and at least one usable wireless interface. The controller of the transmission node determines the broadcast order based on the response message received by the receiver. The transmitter of the transmission node performs broadcasting or multicasting using the wireless interface, which is selected based on the broadcast order. Thus, it is possible to perform broadcasting or multicasting at an efficient usage of radio frequency while covering all reachable neighboring nodes in node-to-node wireless communications based on multiple wireless communication methods.

摘要： A mechanism by which handoff delay can be minimized while not compromising the IMS/MMD security and also protecting the media if required by certain applications is presented. Methods for mitigating delay during SA re-association and mitigating the IPSec tunnel overhead for signaling and media at the Mobile Node are given. In one embodiment, SA keys can be transferred from the old P-CSCF to new P-CSCF, enabling the establishment of SAs before Mobile Node physically moves to the new subnet in a network. Proactive handover is used. In another embodiment, SA keys are transferred from S-CSCF to new P-CSCF. In this case, the SA keys are transferred to the new P-CSCF by S-CSCF through a context transfer mechanism well in advance so that SAs may be established before Mobile Node physically moves to new subnet. In another embodiment, methods for mitigating IPSec tunnel overhead are presented.

摘要： As shown in FIG. 2, when the SYN segment is detected, the amount of transmitted segment from the side which sent the detected SYN segment is obtained by counting the continuously detected DATA segments for collecting the traffic in a certain direction where it is impossible to directly capture the traffic. Further, the amount [ini_sdt] of the transmitted bytes from the side which sent the detected SYN segment is obtained by calculating the equation [ini_sdt]=[SEQn+LENn]−[SEQ1]. Wherein, [SEQ1] is the sequence number of the first detected DATA segment, [SEQn] is the sequence number of the last detected DATA segment and [LENn] is the user data length of the last detected DATA segment.

摘要： A mobile host MH and its home network HN correspond to both the Internet Protocol version 4 (IPv4) and the Internet Protocol version 6 (IPv6). An authentication server (RS) is accommodated in the home network HN. A corresponding host H corresponds to the IPv6 and is accommodated in the IPv6 network. In addition, a plurality of relay servers S1, S2 and S3 corresponding to both the IPv4 and the IPv6 are accommodated in the IPv6 network. The respective S1, S2 and S3 extract an IPv6 packet by decapsulating the IPv4 packet received from the mobile host MH via the IPv4 network, and transfers the relevant IPv6 packet to the corresponding host H via the IPv6 network.

摘要： A data communication method and apparatus for a mobile network. A destination foreign agent (FA2) recognizes a MAC address of an MN. The FA2 registers the MAC address of the MN in a handoff request message (FHReq), and the FA2 feeds the FHReq onto a transfer network. Each of foreign agents (FAs) receives the FHReq, registers an IP address corresponding to the MAC address in the FHReq when the MAC address is registered in a binding list of the FAs themselves, and feeds the IP address onto the transfer network. The FA2 receives the FHReq, and temporarily registers the MAC address and the IP address in the binding list of the FA2 itself. The FA2 transfers data sent from a homw agent (HA) to the MN, based on the information which has been temporarily registered.
