ABSTRACT:
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.
