  • Patent number: 9230434
    Abstract: Provided are a server and a system that are capable of generating road traffic information on traffic congestion in a more appropriate manner, considering actual road traffic conditions. If a vehicle speed V falls below a first reference speed V1 and then exceeds a second reference speed V2 (>V1), then a traffic congestion situation is estimated based on an inference that the vehicle is highly likely to have escaped from traffic congestion. To estimate a traffic congestion situation, it is required that a situation in which the vehicle speed V exceeds the second reference speed V2 continue for a second specified distance or more or for a second specified time T2 or more.

  • Patent number: 5835023
    Abstract: In a mobile radio communication system wherein, in order to call a receiver from a base station, a paging signal containing address information corresponding to the receiver to be called is transmitted n times, the position of a paging signal that is transmitted for the second or subsequent time is determined, in accordance with a prearranged rule, in relation to the position of the same paging signal when it was transmitted for the first time, and the receiver achieves more efficient battery savings by stopping its receiving operation with respect to signal portions which have been confirmed as having already been received without error. The receiving operation is intermittently stopped at a timing corresponding to identical signal portions of the same repeatedly received paging signal.

  • Patent number: 5736934
    Abstract: In a mobile radio communication system wherein mobile units are paged by repeatedly transmitting the same paging signal in n paging signal frames, the number of times a paging signal has been transmitted can be known at the receiving side without the need to transmit additional information, and a time diversity reception scheme can be employed at the receiving side, by forming the paging signal frames from n fixed-length subframes each of which contains a paging signal, and by positioning subframes that contain a new paging signal at one end of the paging signal frames, and, in the case of subframes containing paging signals that will be transmitted for the second or subsequent time, by arranging such subframes with a stagger in accordance with this number of times.
