Abstract: A translation apparatus retains a first correlation between a Mobile IPv6 terminal's home address and virtual IPv4 address. When the Mobile IPv6 terminal transmits a packet to said IPv6 network with a care-of address specified as the packet's source address and a home address specified in an extension header, the translation apparatus changes the packet's source address to a virtual IPv4 address that corresponds to the packet's home address in accordance with the first correlation, and then transmits the packet to an IPv4 network. Mobile IPv6 terminal-to-IPv4 terminal communication can then be established between an IPv6 network to which Mobile IPv6 terminals are connected and an IPv4 network to which IPv4 terminals are connected.

Abstract: A method of relaying data between a first terminal device connected to a first network and a second terminal device connected to a second network comprises: searching in a storing device based on location information accompanying data received from the first terminal device or the second terminal device, the storing device storing location information indicative of a location of at least the first terminal device; as a result of the searching, if the location information exists in the storing device, converting the location information accompanying the data so that the location information stored in the storing device becomes a new location information of the data; and sending the data accompanied with the location information having been converted to the second terminal device or the first terminal device.

A communication system, which generates tunnels in physical lines and multiplexes a plurality of sessions on the physical lines, comprises a monitor unit for monitoring the state of use of tunnels and sessions used by the user when the user using a plurality of tunnels is a customer who requires service of reserving sessions in a smaller number of tunnels in exchange for a specified service fee; a tunnel/session control unit performs control so as to gather the plurality of sessions of said user in a specified tunnel when the sessions currently used by the user can be reserved in a smaller number of tunnels; and a charging unit for charging a usage rate according to the number of tunnels or the number of physical lines used.

Abstract: An IPv6 mobile packet communication network in which mobile VPN service can be provided without having to use a mobile tunnel. A control signal for enabling packet data transmission and reception is sent from a mobile terminal to a gateway node. Using destination-of-connection information contained in the control signal, the gateway node checks whether mobile VPN service is requested or not. Upon detection of a mobile VPN service request, the gateway node returns IP address information of the gateway node to the mobile terminal via a subscriber node. The mobile terminal then assembles an IPv6 header (210) and an IPv6 routing header (220) so that packet data will be unexceptionally transferred through the gateway node.

Abstract: A switching system for realizing integration of existing communication networks or interconnections thereof, and a switching control method. After a call is originated from an ATM communication network 101 to an STM communication network 102, an ATMIF 20 that has received a connection request signal (control signal) converts the control signal into a format of an ATM cell 1000, adds a header destined to one of SIG 50-1 to n for processing control signals, and then output the same. An ATMSW 10 performs self-routing based on header information. The selected one of the SIG 50-1 to n performs conversion for the ATM cell 1000 by a specified protocol, makes an ATM cell 1100 having a header destined to one of CLP 630-1 to k for processing control signals, and then output the same. Upon having received the ATM cell 1100, the CLP 630 links up with other processors to perform call connection control, functions having been dispersed among the other processors.

Abstract: A plurality of packet gate ways (PGWS) are connected between a mobile communication system and an internet so that the corresponding IP subnetworks to those PGWs may be built. A visitor location register (VLR) operates to notify the PGW of location information of the mobile station (MS) and an IP address of a data terminal connected with the MS. If the notified IP address belongs to another IP subnetwork, the PGW notifies the corresponding PGW to that IP subnetwork of a fact that the local PGW is a destination. The PGW operates to manage the location information of the MS connected with the data terminal based on the notified content and perform the packet routing based on the managed content.

Abstract: A method to provide data communication service, which enables each service provider to provide each user with both contents service and Internet connection service. The method provides an Internet service provider with an AT-GW 341 used to authenticate the user, hold a network address assigned to the user, and translate a network address, which is different from a network address held by the user, thereby establishing communication between the user computer and the Internet service provider. The configuration of the present invention thus enables the user to receive high quality contents service and Internet connection service provided from a communication enterprise concurrently.

Abstract: A push-type information providing service, wherein a request for setting management information as to information service to a mobile terminal 2 is issued from a service management node 4 for managing a visit location of the mobile terminal to a gateway when the location of the mobile terminal is registered in a mobile packet communication network 12. The gateway 3 requests a push server 1 to start the information service as necessary, and selectively transfers a service information packet received from the push server to the mobile terminal 2.

Abstract: The record of changes in the size of a workpiece, which is measured by a gage head during grinding, is graphed on a color LCD of a control part. It is therefore possible to know if there is an abrupt change or no change in the size of the workpiece during the grinding just by looking at the graph. Thus, the sharpness of a grinding wheel can easily be judged during the grinding.

Abstract: An HDD, to which servo data is written, is fixed on a base. As an upper base moves, a both-end supporting mechanism provided on the upper base approaches a rotation shaft which supports a disk. When the both-end supporting mechanism is brought into full contact with the tip portion of the free end of the rotation shaft, a process of writing servo data is carried out on the disk. While writing the servo data, the rotation shaft is maintained in the both-end supported state, and therefore a non-repeatable vibration of the rotation shaft caused by a rotation of a spindle motor is suppressed. After the servo data writing process, the both-end supporting mechanism is withdrawn from the rotation shaft as the upper base moves.
