To estimate a more useful destination for users. A destination estimation apparatuscomprises a travel route history registration unitstoring a positional information history as a history of positional information of a user, a positional information acquisition unitacquiring the positional information of the user, and a destination estimation unitestimating a destination of the user by taking a location indicated by the acquired positional information as a start point based on the stored positional information history. The destination estimation unitcalculates a reaching level as a degree the user is reaching the estimated destination based on the stored positional information history, and re-estimates a new destination by taking the estimated destination as a start point when the calculated reaching level is equal to or more than a prescribed threshold value.

Adhesive layer-equipped transparent plate and display device

A controller apparatus, when it receives packets addressed to a mobile terminal, implements paging control in which it transmits a paging notification packet to a paging area of the mobile terminal, so as to obtain location information on the mobile terminal and to determine a forwarding destination of the packets. The controller apparatus includes a paging area forming unit having a plurality of algorithms for forming the paging area. The paging area forming unit is configured to form the paging area of the mobile terminal by an algorithm specified by the mobile terminal.

Control apparatus and mobile terminal

In a packet communications system, a control apparatus implements routing control of a received packet directed for the mobile terminal. The mobile terminal includes a plurality of network interface cards; a communication manager configured to select at least one network interface card among from the plurality of network interface cards, in accordance with information regarding the network interface card; and an upper layer manager configured to receive the packet transmitted from the control apparatus, with using a selected network interface card.

Mobile terminal, control apparatus, home agent and packet communications method

A mobile communication system comprises a plurality of transfer devices configured to transfer packets to a visited position of a mobile terminal, a plurality of connection management devices arranged in a network and configured to connect to the mobile terminal, and a mobile terminal including a detection unit configured to detect the transfer device, and a communication unit configured to connect to the connection management device, and transmit/receive packets to/from the transfer device detected by the detection unit via the connection management device.

Mobile communication system, mobile terminal transfer device, and mobile communication method

A network system implements paging control in which the control apparatus, upon receiving a packet destined for a mobile terminal, transmits a paging notification packet to a paging area of the mobile terminal, so as to obtain location information of the mobile terminal and to determine a transfer destination of a received packet. The control apparatus is configured to transmit the paging notification packet to a plurality of router devices included in the paging area. Each of the plurality of router devices is configured to transmit a received paging notification packet to a plurality of access points by multicasting. Each of the plurality of access points is configured to transmit a received paging notification packet to the mobile terminal through a link connection by multicasting, when it is judged that an IP address in the paging notification packet is a predetermined IP address.

Reducing paging control traffic in a mobile system by placing router identifications in the uplink pagin request packet

A mobile hostas an embodiment of the invention comprises a data link layer connection establishment notification unitfor notifying the network layer that a connection to a link layer in the data link has been established during a Dormant state; a router information requesting unitfor transmitting, in response to the notification by the data link layer connection establishment notification unita router request signal which requests for transmission of router advertisement information to the access routerexisting on the access linkto which the mobile host is connected; and a network layer movement detection unitfor detecting a default router, based on the router advertisement information returned from the access routerin response to the router request signal.

Mobile host, paging agent, packet communication system, and movement detection method

A communication system includes a MN for transmitting a request for information which specifies a MAP to be used for packet reception and anycast address regarding a plurality of MAPs to a given AR connected to the MN, routers for transmitting the request to a MAP which has a shortest distance from the given AR based on the anycast address transmitted from the given AR, and each of the MAPS for transmitting the information which specifies the MAP to the MN.

Mobile node for transmitting a request for information which specifies a transfer device to be used

A mobile node having two or more interfaces, a control method of the mobile node, and a mobile node control program are disclosed. The mobile node includes a generating unit to generate control information for each interface, an information providing unit for providing the control information provided by each interface to an upper layer, and a routing controlling unit to perform at least one of determining connectivity, and updating a routing based on the provided control information.

Mobile node, a control method thereof, and a mobile node control program

Provided is a mobility management node capable of forming a paging area, without need for management of a migration history at a mobile node and for notification of a migration history from a mobile node to a network. In mobility management node (MAP), mobility managerlets binding cachestore a home address and a c/o address of each mobile node (MN) in correlation with each other. Migration history storagestores a transition frequency of the c/o address stored in binding cachein correlation with prefixes before and after transition. Migration history storagedefines paging area information by a set of prefixes included in combinations containing common prefixes, out of combinations of prefixes before and after transition with each of which a transition frequency over a predetermined reference value is correlated. Paging controllernotifies the MN of this paging area information.

Mobility management node, paging area forming method, and mobility management program

An object of the present invention is to decrease a care-of address update duration in switching of a link used for connection to an IP network by a mobile node (MN). MN acquires a list of access routers (ARs) existing on neighboring links to the link used for connection by the mobile node and creates a list of care-of addresses (CoAs) corresponding to the respective ARs entered in the list, each CoA being used as a destination of MN at a link on which an AR corresponding thereto exists. After the change of the connected link, MN acquires a data link layer address of AR existing on the link after the change and detects a default router on the basis of the address with reference to the access node list. Furthermore, MN detects a CoA with a network prefix corresponding with a subnet prefix of the default router, as a primary CoA and requests MAP to register a binding between the primary CoA and HoA.
