摘要： In a handover control apparatus, a terminal is wirelessly connected with one of base stations to establish a wireless data communications connection. The terminal executes a handover process using a handover process section when an electric wave state becomes lower than a threshold value, which is variable. The threshold value can be adjusted according to a moving speed of the terminal. Furthermore, the threshold value is corrected according to the past electric wave state. The threshold value is corrected according to a difference of (i) a minimum electric wave state in a preceding handover process, and (ii) a lower limit. The correction is executed so as to reduce an excessive decline of an electric wave state in a succeeding handover process. Deterioration of a communications quality during a handover process can be thereby suppressed.

摘要： A radio communication terminal is used in a position specifying system, in which both retrieval timing and retrieval time of each of GPS satellites are received via a communication base station from a position information server. The position information server specifies a position of the radio communication terminal based upon at least GPS satellite information received from the radio communication terminal. The radio communication terminal corrects at least any one of both retrieval timing and retrieval time so that the retrieval timing is moved, or the retrieval time is prolonged. The radio communication terminal retrieves the GPS satellites based upon the corrected retrieval timing and the corrected retrieval time.

摘要： A cellular phone receives a position measurement result, which indicates a position of the cellular phone determined based on both GPS satellite information and CDMA base station information, from a location information server. Then, when a value indicated by uncertainty information of the position measurement result is greater than a first threshold value, the cellular phone receives another position measurement result, which indicates the position of the cellular phone determined based only on the CDMA base station information, from the location information server and displays it on a display device.

摘要： An on-board communication equipment on each of two vehicles receives a radio wave from two or more GPS satellites, and determines a carrier wave phase of the received radio wave. Then, the on-board communication equipment on one vehicle receives, from the other vehicle, information on the carrier wave phase observed in the other vehicle. Further, the on-board communication equipment calculates a relative position of a self vehicle relative to the other vehicle by a Carrier-Phase DGPS positioning based on a difference between two carrier wave phases (e.g., single difference, double difference or the like), that is, one from the self vehicle and one from the other vehicle, both having the same observation time, from among the available carrier wave phases.

摘要： 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.

摘要： A wireless terminal is designed to prevent the user from having to wait a long time in case fetching of search data takes a long time. The wireless terminal, if it determines the need of long time for the search of GPS satellites by a GPS transceiver, inhibits the GPS transceiver from searching GPS satellites and operates on a CDMA transceiver to search for CDMA base stations. The wireless terminal fetches only CDMA base station data pertinent to the CDMA base stations and sends to a position data server, and the position data server points the location of the wireless terminal based solely on the CDMA base station data provided by the wireless terminal. Based on the inhibition of search of GPS satellites by the GPS transceiver, the time needed until the reception of positioning result can be reduced, and the user is prevented from being subjected to long time waiting.

摘要： In a mobile station, a period for receiving a GPS signal from a predetermined satellite based on data for satellite reception is set up by a timer, and the GPS signal whose reception level is higher than a threshold value is awaited. Until elapsed time reaches a preset time, indoor counter is incremented if the GPS signal is unable to be received or outdoor counter is incremented if the GPS signal is able to be received. When each counter reaches a specified value, each mode is determined. If the mode is different from a previous mode, a mode shift is executed and setups of user interfaces, display, speaker and others, are altered for the updated mode, indoor or outdoor.

摘要： A mobile communication terminal stores positioning information including global positioning system signals and base station information required by a position server in a communication network to calculate the terminal position. When the position server calculates the terminal position based on these positioning unit information, the position information is not reported to the user if the indefinite information equivalent to a positioning error contained in the average value calculated for the terminal position information exceeds a predetermined threshold value. When the average processing count exceeds a maximum positioning count, that average value is reported to the user.
