Abstract: A wireless terminal has the enhanced performance in the attainability of successful search of GPS satellites based on the operation of a position data server. The server sets a GPS satellite search time longer than usual when station data pertinent to surrounding stations is below a prescribed level, when the distance between the wireless terminal and a communication station is beyond a prescribed distance, when the wireless terminal is in such a specific area as seashore, or when a reference station or the communication station is a repeater station. The server sends data of the longer search time to the wireless terminal via the communication station. Setting a GPS satellite search time longer than usual prevents the deviation of the ideal search timing, which enables the optimal search of GPS satellites, out of the search time set by the position data server.

Abstract: A control unit executes base station information collection, acquires base station information collection results, and transmits the base station information collection results to a position server via a radio communications network. A memory stores the base station information collection result. A counter counts a predetermined time. The control unit makes the counter count the predetermined time and makes the memory store the base station information collection result during a time counted by the counter when the base station information collection is started. The control unit then acquires the base station information collection results from the memory after the counter finishes the counting, and transmits the base station information collection results to a position server via the radio communications network.

Abstract: A mobile communications terminal has a transmitter for transmitting a specific identification code of a reference base station as a time reference for network position determination. Therefore, a position server connected with a CDMA network can distinguish the reference base station from the other base stations regardless of positioning relationship between the mobile terminal and the base stations.
