摘要:
The present invention is an authentication method for disclosing identification data of an object and authenticating when referring to data of the object corresponding to the identification data based on the identification data and can associate a tag device and data of a referring entity and authenticate that data of the tag device is referred by a proper referring entity by generating a third value by conducting a predetermined calculation with a temporary first value indicating a most recent referral to the identification data of the object and a temporary reference second value issued to a referring entity of the identification data for each referral, and authenticating a relationship between the object and the referring entity by verifying the third value.

Group information is assigned for each communication object and communication data is transmitted by adding the group identifier, thereby realizing a communication control in accordance with the communication object. That is. when a communication device performing radio communication by constituting an ad-hoc network with a plurality of devices communicates with a destination device via at least one of the devices constituting the ad-hoc network, the communication device acquires group information assigned to the communication group having the common object with this communication, references a communication control data table containing communication control information for each of the group information so as to acquire the communication control information corresponding to the group information, adds the group information to the communication information to be transmitted to the destination device so as to generate communication data, identifies a device which relays the communication according to the communication control information, and transmits the communication data to this relay device.

A group management server receives, from a device joining an ad hoc group related to the provision of a service as a member thereof, a member registration request including communication information inclusive of a method for communication with the device becoming the member and registers the device in the ad hoc group. The group management server provides the communication information to a provider of the service in response to a request from the service provider. The service provider performs communication related to the provision of the service with each of members by using the communication information.

An information distributing system comprises a startup condition management device inputting and holding a startup condition per user possessing a user terminal, inputting and holding context per user, and comparing the startup condition with the context for the same user and outputting, when both are coincident with each other, a service startup request including startup condition information and the context, and a service execution device outputting, when receiving the service startup request, a service execution request corresponding to the user terminal or controllable resources associated with the user terminal based on the startup condition information and the context included in the service startup request. The startup condition information can be provided from the user terminal or the service execution device. The service execution device outputs the service execution request through a service execution auxiliary device as required. The context can be provided to the startup condition management device through the user terminal itself or a context collection device.

A network access control method for a network system comprising network apparatuses having a packet filtering function, a service server connected with an IP network via the network apparatus, providing a service to a user, a user terminal connected with the IP network via the network apparatus, for the user to utilize the service provided by the service server, a reception server connected with the IP network via the network apparatus, receiving an access from the user for the service server, and an access control server controlling the network apparatuses. The method comprising the steps of a) the reception server receiving access request information from the user terminal, and holding it, and b) the access controlling server performing traffic control such as to extract, based on processing capability of the service server and a traffic amount for the service server, such an amount of the access request information as that the service server can optimally deal with, so as to allow the access for the service server.

A context information collection and distribution system registers read identification information in a computer device that manages and controls an RFID tag reading device and is located in a lowest hierarchy in wide area network topology. The computer device located in the lowest hierarchy in the wide area network topology notifies a computer device located in a higher management domain hierarchy that the computer device located in the lowest hierarchy manages read identification information of a target. Further, the computer device located in the management domain hierarchy notifies a computer device located in much higher ID system hierarchy that the computer device located in the hierarchy just under the management domain hierarchy manages the read identification information of the target.
摘要:
Communication terminals are provided with a short range wireless communication interface. Some communication terminals are also provided with a long range wireless communication interface. A communication terminal having both interfaces is determined to become a segment manager by a plurality of communication terminals. A segment manager and its neighboring communication terminals constitute a segment and communicate with each other via the short range wireless communication interface. A segment manager distributes segment information and collects terminal information from communication terminals that belong to its own segment. The segment managers communicate with each other via the long range wireless communication interface. The segment managers exchange the terminal information related to each segment. Communication within a segment is performed through that segment alone via the short range wireless communication interface. Communication toward the outside of that segment is performed via the short range wireless communication interface and the long range wireless communication interface.
摘要:
A network system which provides each terminal user with differentiated service, dynamically changing service profiles even in the middle of a communication session. A service control database maintains service profile definitions. When a mobile node registers with a foreign agent to initiate a conmiunication session, a service profile setting controller in the mobile node's home server sets up a service profile for the mobile user. When an event occurs within a service profile updating controller, it indicates that some control condition specified in the service profile is met. The service profile updating controller then makes access to the service control database to obtain a new service profile and the mobile node's foreign server forwards it to the foreign agent, to which the mobile node is attached. The service profile that has been established in relevant network nodes, including the home agent and foreign agent, is dynamically updated with the new one.
摘要:
A user system for a distributed network whereby a user system which is not provided with a distributed application platform can be connected to a distributed network. A user information unit incorporates therein physical points corresponding to stream and network flow endpoints, respectively. A flow endpoint control channel connects a user signaling unit to the user information unit. The user signaling unit includes distributed communication control means, distributed network service controller, and information unit controller for controlling the user information unit by means of a flow endpoint control signal. The user information unit includes physical point linking unit, and flow endpoint control signal processing unit which cooperates with the user signaling unit by means of the flow endpoint control signal.
