摘要： When a person of holding a mobile station gets near to a previously set target position, application 200 is started and service of utilizing positional information is provided to the person of holding the mobile station or a third party. The mobile station includes a position comparator 103 for comparing a current position of the mobile station calculated by a position calculator 102 by using a signal from an antenna 100 with a target position inputted from means for target position input 104 and an application controller 106 for controlling the application 200 by using a result of position comparison 120. Further, a frequency of position calculation is pertinently controlled in the position calculator 102 by a position calculation controller 107 operated by the result of position comparison 120.

摘要： In a radio paging system and a radio paging method, in which all transmitters are simply synchronized with each other with a satisfactory precision. A central exchange and each transmitter are each provided with a GPS clock for measuring time according to a current time transmitted from the GPS clock. An encoder of the central exchange adds to a message received from a network a real time, which is information to specify time to send the message from each transmitter, according to the current time measured by the GPS clock thereof and then distributes the message to the transmitters. A synchronizing section of each transmitter sends from a transmitting unit the message distributed from the central exchange to a receiver at a time specified by the real time added to the message according to the current time measured by the GPS clock thereof.
