  • Patent number: 11169546
    Abstract: There is provided a control device, configured to control a plurality of flight objects having a solar panel, a battery for storing an electrical power generated by the solar panel, and an antenna for forming a communication area on a ground with the electrical power stored in the battery and providing a wireless communication service for a user terminal within the communication area, the control device comprising: a flight object selecting unit configured to select a to-be-replaced active flight object among a plurality of active flight objects, which are flight objects each flying while covering a target area with the communication area; and a replacement controlling unit configured to replace the to-be-replaced active flight object with a standby flight object, which is a flight object flying without forming the communication area.

  • Patent number: 9736808
    Abstract: A mobile object communication system is configured with the assumption that a base station is fixed. Therefore, signal quality becomes unstable if the base station moves freely. Provided is a control apparatus controlling a relay apparatus that is mounted in a mobile object and relays communication between a base station and a communication terminal, including a mobile object information acquiring section that acquires mobile object information indicating a state of the mobile object and a control section that controls the relay apparatus based on the mobile object information. If the movement speed of the mobile object is judged to be less than a predetermined value, the control section may generate a relay control signal indicating that a relay function of the relay apparatus is to be activated.

  • Patent number: 8938544
    Abstract: A system and method for determining a network is disclosed. The system comprises a requesting module and a determination module. The requesting module sends a request from a vehicle for network data to a connectivity server. The request includes vehicle data describing a current location of the vehicle and a destination for the vehicle. The requested network data is associated with the vehicle data. The determination module receives the network data relating to one or more networks. The determination module caches the network data and determines which network to connect to from the one or more networks based at least in part on the network data.

  • Patent number: 8897806
    Abstract: A system for dynamic data publication and dissemination in a mobile node network is disclosed. The system comprises a collection module, a naming module and a publishing module. The collection module collects sensor data and detects a road event based at least in part on the sensor data. The collection module generates event data that describes the road event. The naming module converts the event data to a set of naming data that conforms to a naming structure. The naming structure includes an application identifier that identifies an application for the road event and a location that identifies a geographical scope for the road event. The naming module caches the set of naming data in a storage device. The publishing module publishes the set of naming data in the mobile node network.

  • Publication number: 20130094516
    Abstract: A system and method for borrowing one or more time slots for data transmission is disclosed. The system comprises a monitor module, a request module and an allocation module. The monitor module detects a trigger event for borrowing a time slot from a potential lender. The request module generates a borrowing request responsive to the trigger event. The allocation module receives a response responding to the borrowing request from the potential lender. The allocation module determines whether the borrowing request is approved based at least in part on the response. Responsive to an approval of the borrowing request, the allocation module allocates one or more designated time slots included in a first active period and the borrowed time slot included in a second active period for data communication.
