Abstract: Disclosed method and apparatus for automatic information filtering are capable of improving both precision and recall and accurately judging inappropriateness of the content even for a page that contains very few or no text information and only displays images, by utilizing an upper level URL of a URL given in a hierarchical structure. Also, disclosed method and apparatus for automatic information filtering are capable of setting weights of words easily and accurately and judging inappropriateness of the information by utilizing these weights, by using an automatic learning based on a linear discrimination function that can discriminate the inappropriate information and the appropriate information on a vector space.

Abstract: 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.

Abstract: 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.

Abstract: 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 and obtains a new IPv4 address. After determining that the visited network contains no IPv6-enabled components, the node uses in 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 node has moved but still uses the same connect agent. The node sends a binding update to the connect agent 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 current care-of address, thereby reducing packet loss.

Abstract: An Internet Service Provider provides IPv6 connectivity to a customer without requiring that the customer upgrade its network containing IPv4 components. The Internet Service Provider makes at least one point of presence including at least one IPv6 Connect Agent available to customers. The Internet Service Provider allows a customer's IPv6 enabled node located within the customer's network containing IPv4 components to automatically discover an IPv6 Connect Agent. The Internet Service Provider facilitates IPv6 communication between the customer's IPv6 enabled node and the discovered IPv6 Connect Agent, across the customer's network containing IPv4 components.

Abstract: When a call is received at the TAD from telephone 1 via exchange A2 and exchange B3, the TAD transmits an outgoing message. In response to the aforementioned message, the caller transmits a message or telephone number data regarding his own telephone. After the TAD records the telephone number, it calls up portable telephone 6 by autodialing. When TAD and portable telephone 6 are in a connected condition via base station 5, and if TAD sends the telephone number data in a predetermined format, it will be displayed upon the display unit of portable telephone 6.
