Patent number: 9736808Abstract: 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.Type: GrantFiled: November 29, 2015Date of Patent: August 15, 2017Assignee: SoftBank Corp.Inventors: Yoshioki Chika, Keith Sutton, Ryuji Wakikawa

Patent number: 8938544Abstract: 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.Type: GrantFiled: March 9, 2012Date of Patent: January 20, 2015Assignee: Toyota Jidosha Kabushiki KaishaInventors: Ryuji Wakikawa, Roger D.

Patent number: 8897806Abstract: 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.Type: GrantFiled: October 8, 2012Date of Patent: November 25, 2014Assignee: Toyota Jidosha Kabushiki KaishaInventors: Ryuji Wakikawa, Rama Krishna Vuyyuru, Romain Kuntz

Publication number: 20130094516Abstract: 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.Type: ApplicationFiled: March 15, 2012Publication date: April 18, 2013Applicants: TOYOTA INFOTECHNOLOGY CENTER CO., LTD., TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Ryuji Wakikawa, Romain Kuntz, Surjya Sarathi Ray
