In the presence information management method of the present invention, the e-mail address of the user and the terminal address of a terminal are extracted upon receipt of an e-mail transmission request, the e-mail address and terminal address correspondence table is retrieved by using the extracted e-mail address, and the extracted terminal address is registered in the e-mail address and terminal address correspondence table if the retrieved terminal address does not correspond to the extracted terminal address. Thus, the user can automatically update presence information with his/her e-mail transmission request.

Location information management method and location management system

A wireless communication system includes: a first wireless communication terminal to register an external device, wherein a subscriber information management device transmits a location of the external device to the first wireless communication terminal based on a search result of the external device based on a search request for the external device, the search request being transmitted from the subscriber information management device to a second wireless communication terminal within a search target area, the second wireless communication terminal being identified by the subscriber information management device based on registration information including certain information and location information of the external device.

Wireless communication system, wireless communication terminal, and subscriber information management device

A mobile terminal device including a first housing, a second housing, the device having multiple configurations, including a first configuration in which the second housing is closed with respect to the first housing, a second configuration in which the second housing is slid relative to the first housing from the first configuration, and a third configuration in which the first housing is separated from the second housing, and a first input key is provided on the first housing, and is covered with the second housing in the first and second configurations and is exposed in the third configuration.

Mobile terminal device

A filter-information transmitting/receiving unit transmits path information with the filter information when the filter information is set by a filter setting unit, and receives the path information when the filter information is set in other network device. A filter-combining determining unit determines whether redundant filter information with the other network device is to be combined or deleted, based on the filter information and the path information. A filter control unit issues a filter-setting request or a filter release request based on a result of determination by the filter-combining determining unit.

Network device and computer product

A secure data communications system with an enhanced function of preventing information leakage. The system includes a user terminal and a router. The router has a security condition definition unit and a storage unit to receive and store a set of security conditions. A packet parser identifies and parses a packet produced by a file transfer application protocol and extracts from that packet a destination address and a security condition ID that the sending user has specified for a file in the packet. The packet parser discards the packet to prevent information leakage if the extracted destination address does not satisfy the security condition corresponding to the user-specified security condition ID. The user terminal has a security condition user interface that requests the router to provide information about security conditions and gives a security condition ID to each file to indicate which security condition the sending user has specified.

Communications system with security checking functions for file transfer operation

The provider network that interconnects user networks includes a plurality of edge routers. At least one of the plurality of edge routers includes an obtaining unit for obtaining information of a packet transferred by the edge router itself, a creating unit for creating a flow list in which flow information of packets transferred from the user network side to the provider network side is registered based on the packet information, a monitoring unit for monitoring a traffic state of a flow of each packet registered in the flow list based on information of packets transferred from the provider network to the user network, and a notifying unit for notifying the traffic state of the flow registered in the flow list to a maintenance engineer.

Provider network for providing L-2 VPN services and edge router

To collectively manage user networks connected to a virtual private network (VPN) without such time and effort necessary for an operation management server to be ready for an expansion MIB for each of vendors. Provided is a network management system, including: a first edge router, an operation management server and a second edge router which connects to the first edge router, the second edge router being included in the network constituted for each of the user groups, wherein the first edge router includes: collecting unit for collecting management information regarding constituent elements of the network constituted for each of the user groups from the second edge router on the network constituted for each of the user groups, unit for storing the management information in correspondence with the virtual private network for each of the user groups, and unit for returning the management information when receiving, from the operation management server, a request for the management information brought in correspondence with the virtual private network for each of the user groups, and the operation management server includes requesting unit for designating the virtual private network for each of the user groups and requesting the first edge router to return the management information regarding the constituent elements of the network constituted for each user group connected to the virtual private network.

Network management system, and network management method

A route computing system is capable of computing routes at a high speed at a low cost without the need for replacing the hardware of a transmission device. The transmission device has a destination information receiving unit for receiving destination information indicative of the destination of a packet from a terminal device. The transmission device also has a destination information storing unit for storing the destination information, and a routing packet sending unit for receiving a routing protocol packet from another transmission device and sending the routing protocol packet to the terminal device. The terminal device has a routing packet receiving unit for receiving the routing protocol packet sent from the routing packet sending unit. The terminal device also has a computing unit for recomputing the destination information based on the routing protocol packet, and a destination information sending unit for sending the recomputed destination information to the destination information receiving unit.

Route computing system

Network interconnection apparatus and method capable of efficiently guaranteeing optimum QoS suited to the status of actual traffic and network, whereby high-performance network interconnection is achieved without entailing lost calls. Routing information managing means manages routing information of an ATM network, and statistical information managing means manages statistical information on the traffic of a LAN. QoS setting means sets QoS which the ATM network ought to guarantee, based on the statistical information, and QoS guarantee determining means determines based on the routing information whether or not the set QoS can be guaranteed. If it is judged that the QoS cannot be guaranteed, QoS adjusting means adjusts the QoS so that the QoS can be guaranteed. Call connection control means connects call according to the QoS which can be guaranteed.
