  • Patent number: 7277948
    Abstract: 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.

  • Publication number: 20070124309
    Abstract: In a content retrieval system where an update frequency of content is extremely high, based on a content reference request from a client which generates the content reference request including unique information and an attribute of a desired content, a cache server checks a presence/absence of a cache of the content, caches the content from a content server to transmit the content to the client in the absence of the cache of the content, or transmits the content held to the client in the presence of the cache of the content. Then, the cache server performs synchronization mirroring with the content server based on the attribute.

  • Patent number: 7068640
    Abstract: Linked with a position registration procedure in a mobile IP, the invention provides a VPN setting service using an IP Sec. tunnel between optional terminals without requiring these terminals to have a specific VPN function. This service is provided by a mobile terminal, authentication servers, a VPN database, and network apparatuses. A home authentication server extracts from the VPN database the VPN information of a user who has requested the authentication at the time of making a position registration request from the mobile terminal. The home authentication server then posts the VPN information to each network apparatus using a predetermined position registration message and an authentication response message. Based on the posted VPN information, the network apparatuses set a VPN path by the IP Sec.

  • Publication number: 20040037260
    Abstract: A home agent (HA) is endowed with a gateway function having a security function of an enterprise network. A VPN is established beforehand between the home agent arranged in a communications carrier and a security gateway within the enterprise network, when a service contract is made between the communications carrier and the enterprise. As a result, co-located mode of a mobile node (MN) is used, and VPN information according to a security level of a network that accommodates the mobile node is distributed in a location registration procedure of a mobile IP, so that a VPN that effectively uses a tunnel set-up process of the mobile IP is configured.

  • Publication number: 20030196118
    Abstract: The present invention relates to an IP network including mobile environment and, in particular, to a service control network and its control method for providing individual service every user or terminal of an IP network. In a service control network including a service control device for performing Layer-7 service control for mobile terminals, an authentication server device specifies a Layer-7 profile and an associated dependent Layer-3 profile of a mobile terminal at the success of the authentication of the mobile terminal. An edge device transfers packets, which have been received from the mobile terminal after the success of the authentication of the mobile terminal and match the dependent Layer-3 profile, to the service control device. The service control device controls the implementation of a Layer-7 service for packets which have been received from the edge device and match the Layer-7 profile.
