摘要： A mobile dual-stack node engages in IPv6 communication while roaming within an IPv4-only network. The node determines that it has moved and obtains a new IPv4 address. After determining that the visited network contains no IPv6-enabled components, the node communicates with a tunnel broker to obtain a care-of address and a tunnel to an IPv6 connect agent (e.g., a tunnel server). If the obtained care-of address differs from the care-of address that the node had been using prior to the move, the node sends MIPv6 binding updates to its home agent and corresponding peers. The node can optimize the handoff when it has obtained a different care-of address by sending a binding update to the connect agent comprising the previous care-of address and the current care-of address. When the connect agent receives a packet destined for the previous care-of address, it forwards the packet to the current care-of address.

摘要： A mobile IPv6 dual-stack node engages in IPv6 communication while roaming within an IPv4-only network, for example using ISATAP. First, the node determines that it has moved Bnd obtains a new IPv4 address. After determining that the visited network contains no IPv6-enabled components, the node uses an IPv6 connect agent to engage in IPv6 communication. The node configures its care-of address using the IPv6 connect agent's routing information and the node's newly-obtained IPv4 address. In one embodiment, the node and the connect agent optimize the handoff when the nodes has moved but still uses the same connect agent. The node sends a binding updates to the connect agents comprising the node's old care-of address and the node's new care-of address. When the connect agent receives a packet destined for the node's previous care-of address, it forwards the packet to the node's currents care-of address, thereby reducing packet loss.

摘要： An IPv6 enabled node finds an IPv6 connect agent by using a Domain Name System (DNS) server. The IPv6 enabled node sends a query to the DNS server and, in response, receives one or more identifiers of one or more IPv6 connect agents. In one embodiment, an identifier comprises the name of an IPv6 connect agent. In this embodiment, the IPv6 enabled node then sends a name of a desired IPv6 connect agent to the DNS server and, in response, receives the address of that IPv6 connect agent. The IPv6 enabled node is then able to engage in IPv6 communication using that IPv6 connect agent. In another embodiment, an identifier comprises the address of an IPv6 connect agent. In this embodiment, the IPv6 enabled node is able to engage in IPv6 communication using that IPv6 connect agent without any further contact with the DNS server.

摘要： The present invention advantageously provides several systems and methods for solving the trombone routing issues within an IMS/MMD network. These approaches avoid trombone routing, speed up handoff, and increase the efficiency of signaling and overall performance of an IMS/MMD network. These solutions can broadly be divided into the following categories. Piggy-backing SIP registration over MIP (Split at FA); Selective Reverse Tunneling and Tunneling between FA and P-CSCF; the SIP-based mobility protocol; use of CoA during SIP registration and call up in MIPv6; Piggy-backing SIP registration when HA and S-CSCF Co-exist; Using Dynamic Home Agents in MIPv4 FA-CoA; and the Interceptor-Caching Approach.

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： The frequency of an information signal indicative of a-vibration of a wheel detected by an acceleration sensor mounted to a wheel; or a change in the pressure of a gas in a tire detected by a pressure sensor installed in the tire, is analyzed. The band value of the obtained vibration spectrum or pressure change spectrum is detected, and a vibration level or pressure change level at the detected frequency band is compared with: a vibration level table showing the relationship between road friction coefficient μ and vibration level; or a pressure change level table showing the relationship between road friction coefficient μ and pressure change level, to estimate a road friction coefficient μ. Therefore, it is possible to estimate the value of road friction coefficient μ accurately and improve the safety of a car.

摘要： A pneumatic tire includes a body having a plurality of main body cords. The tire includes an upper section above the maximum section width and a lower section below the maximum section width. The modulus of the body cords is configured to be larger in the lower section than in the upper section. This modulus ratio decreases the rolling resistance of the tire. The increased modulus in the lower section is achieved by providing a body cord insert wrapped around the bead core and bead filler. The ends of the body cord insert are disposed against each other so that the entire bead filler is surrounded. The body cord insert extends substantially over the entire lower section of the tire.

摘要： An amount of data to be distributed to each receiving terminal is dynamically controlled for each receiving terminal in response to a congestion of each of plural receiving terminals. When a determination of an RR (Reception Report) returned from the receiving terminal results in a very low rate of packet loss, an adaptive control mixer distributes communication data transmitted from a transmitting terminal to the receiving terminal without reducing the communication data. On the other hand, the determination of the RRs returned from the receiving terminals results in a high rate of packet loss, for example, 50% and 90%, respectively. In this case, the adaptive control mixer reduces, for example, 50% of the communication data transmitted from the transmitting terminal and then distributes the data to the one receiving terminal. The adaptive control mixer reduces, for example, 90% of the communication data and then distributes the data to the other receiving terminal.
