Abstract:
A control method and device, as well as a system, are provided that make it possible to perform relocation at an appropriate timing without impairing a user's sensory feeling about use of a service. A relocation control device 301 that controls relocation of a packet network gateway 100a which provides functionality as an anchor for ensuring mobility of a mobile terminal in a mobile communication system, includes a bearer information acquisition section 311 that, when an occasion for relocation arises, acquires information to obtain importance and a use state of a communication between a mobile terminal 50 and the packet network gateway 100a, and a relocation determination section 312 that determines whether or not to perform relocation, based on the importance and the use state of the communication.

Abstract:
An access gateway (GW) receives, from a mobility management node, a transmission-path control signal for changing a route of only part of a data packet flow that pertains to a mobile terminal and is originally relayed through the access GW and a first mobility anchor. In response to receiving the transmission-path control signal, the access GW establishes a logical transmission path with a second mobility anchor for transferring the part of the data packet flow, and transfers the part of the packet flow to the second mobility anchor and also transfers a remaining part of the packet flow to the first mobility anchor by distinguishing a data packet received from the mobile terminal.
Abstract:
A communication system comprises: a path management server that generates a plurality of forwarding path information items each includes a sequence of identifiers, each of which identifies a communication interface provided in each of a plurality of forwarding nodes on a forwarding path in a data forwarding network or a link established between the forwarding node and a neighboring node thereof; and a forwarding node that, in accordance with at least one of the plurality of forwarding path information items, executes a packet forwarding processing of a packet with a header including the plurality of forwarding path information items.
Abstract:
A home network system in which an appropriate mobility anchor is allocated for a mobile node and the number of mobility anchors can be reduced. A subscriber information accumulation server accumulates first communication load prediction data for each time of a mobile node. An anchor information accumulation server accumulates second communication load prediction load for each time of each mobility anchor. When “a mobility anchor allocation request” is transmitted from the mobile node to an anchor allocation server, the anchor allocation server adds the first communication load prediction data and the second communication load prediction load data so as to obtain third communication load prediction data. Among a plurality of mobility anchors, a mobility anchor in which the third communication load prediction data is not greater than the load upper limit value at all the times and the maximum value of the second communication load prediction data is minimum is selected and allocated.
Abstract:
A communication system comprises a path management server that configures forwarding path information that is configured by arranging link IDs for identifying communication interfaces provided in respective forwarding nodes in a forwarding path of a data transfer network or links extending between said respective forwarding nodes and neighboring nodes thereof. For packets to which is added a header containing the forwarding path information, a forwarding node performs packet forwarding processing in accordance with the forwarding path information.
Abstract:
A communication system (1) includes an anonymizing device (100) and a server (200). The anonymizing device (100) generates an anonymous address based on a prefix acquired from the server (200), receiving a packet transmitted from a communication node (300), rewrites a source address of the received packet into an anonymous address, encapsulates the received packet, and sends the packet to a second network (600) using the address of the anonymizing device (100) as a source address of the encapsulated packet and the address of the server (200) as a destination address. Then, receiving the encapsulated packet transmitted from the anonymizing device (100), the server (200) decapsulates the encapsulated packet and sends the packet to the second network (600). High anonymity can be thereby assured.
Abstract:
A broadcast receiver terminal receives a broadcast program with advertisement ID information inserted therein, outputs the program, and transmits the ID information through proximity communication. An advertisement viewing confirmation terminal receives, if it is determined that a user is carrying about the confirmation terminal according to a temperature, the ID information through the proximity communication and then creates viewing information by adding user information to the advertisement ID information.
Abstract:
Provided is a home network system in which an appropriate mobility anchor is allocated for a mobile node and the number of mobility anchors can be reduced. A subscriber information accumulation server (14) accumulates first communication load prediction data for each time of a mobile node (32). An anchor information accumulation server (15) accumulates second communication load prediction load for each time of each mobility anchor (11). When “a mobility anchor allocation request” is transmitted from the mobile node (32) to an anchor allocation server (13), the anchor allocation server (13) adds the first communication load prediction data and the second communication load prediction load data so as to obtain third communication load prediction data. Among a plurality of mobility anchors (11), a mobility anchor in which the third communication load prediction data is not greater than the load upper limit value at all the times and the maximum value of the second communication load prediction data is minimum is selected and allocated.
