Abstract: An information processing apparatus is provided, including: a prediction result obtainment unit which obtains a result of prediction of weather in stratosphere; and a flight path determination unit which determines a flight path of a flight vehicle based on the result of prediction of weather in stratosphere such that the flight vehicle flies through an area in stratosphere that has been predicted to satisfy a predetermined stratospheric path condition, wherein the flight vehicle functions as a stratospheric platform, and forms a wireless communication area by emitting a beam and provides a wireless communication service to a user terminal in the wireless communication area.

Abstract: An off-load apparatus is disposed between a core network accommodating base stations and the base stations capable of connection with a mobile station. The off-load apparatus includes a storage unit that stores line information and multicast viewing information of the mobile station when the mobile station performs multicast communication of an off-load object via the off-load apparatus; a transferring unit that transfers the line information and the multicast viewing information of the mobile station to another off-load apparatus that is an handover destination when the mobile station moves during the multicast communication; and a control unit that executes a process of participating in multicast viewing on behalf of the mobile station when the off-load apparatus acts as a handover-destination apparatus, based on the multicast viewing information transferred from a handover-source off-load apparatus.

Abstract: A network system including: a first and second radio base station apparatuses which are connectable with a mobile station apparatus; a first network which accommodates the first and second radio base station apparatuses; a first offload apparatus which relays packet data, and transmits to a second network a portion of packet data transmitted from the first radio base station apparatus after rewriting a first address of the mobile station apparatus with a second address, or transmits to the first radio base station apparatus packet data received from the second network after rewriting the second address with the first address; and a second offload apparatus, wherein the first offload apparatus includes a first control unit which transmits the second address to the second offload apparatus, and the second offload apparatus includes a second control unit which receives the second address.

Abstract: A network system includes: a plurality of base stations, each with which a mobile station communicates; a core network to include the plurality of base stations; and a plurality of offload devices, each being arranged between the base station and a node device included in the core network, each to serve as the node device of an anchor point at which traffic to be offloaded is transmitted/received to/from an offload network, and each to serve as the node device of a relay point at which the traffic to be offloaded is relayed between the anchor point and one of the plurality of base stations with which the mobile station is communicating.

Abstract: An information processing device including: a first storage unit that stores content; a second storage unit that stores session information including a home address and a care-of address of a mobile terminal, a home address of a virtual proxy, distribution content, and a state of the session; and a processing unit that updates, when a location registration request is received from a mobile terminal that is establishing a session, session information based on the location registration request, searches for an information processing device located near the mobile terminal, and notifies the detected information processing device of the session information and that transmits, when session information related to a mobile terminal that is establishing a session with another information processing device is received, to the mobile terminal, a location registration request including an address of the virtual proxy and distributes content included in the session information.

Abstract: A network system includes: a plurality of base stations, each with which a mobile station communicates; a core network to include one or more gateways, each with which the plurality of base stations communicates; a plurality of offload devices, each arranged between the base station and the gateway, each to serve as the gateway of an anchor point at which traffic to be offloaded is transmitted to or received from an offload network, and each to serve as the gateway of a relay point at which the traffic to be offloaded is relayed between the anchor point and one of the plurality of base stations with which the mobile station is communicating; a control station to control the traffic between the mobile station and the gateway; and one or more interception devices, each to intercept the traffic between the control station and the gateway.

Abstract: A first route selecting apparatus that is included among a plurality of route selecting apparatuses includes an acquiring unit that acquires for handover of communication currently relayed by the first route selecting apparatus, a selection state of a relay route of a second route selecting apparatus that is included among the route selecting apparatuses that each selects from among a first route and a second route, a relay route between a mobile terminal and a communication destination, and that when a traffic amount of the first route becomes at least a predetermined amount, selects the second route for communication established for a communication request issued thereafter; and a selecting unit that according to the acquired selection state, selects the second route for the currently relayed communication even when the traffic amount of the first route is less than the predetermined amount.

Abstract: A usage management system includes a first storage and a processor. The first storage stores, for each communication area and for each user, usage restriction information regarding a network device which locates in each communication area and which is used by each user and connectable to a communication network. The processor identifies a location area which is a communication area in which a target network device locates, identifies a target user present in the identified location area, acquires usage restriction information regarding the target network device for the identified target user from the first storage, and controls operations of the target network device in accordance with the acquired usage restriction information.
