Wireless terminal
First Claim
1. A wireless terminal comprising:
- a plurality of search means which are provided in correspondence to a plurality of positioning systems including the Global Positioning System and the Mobile Phone System and each of which is adapted to search for stations of a corresponding positioning system; and
control means which fetches search data pertinent to the stations searched by the multiple search means and sends the fetched search data from a transceiver to a position data server, the control means, if a prescribed condition is met, inhibiting the operation of a first search means among the multiple search means and sending only search data fetched by a second search means among the multiple search means from the transceiver to the position data server.

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.

12. A wireless terminal comprising:
-
a plurality of search means which are provided in correspondence to a plurality of positioning systems including the Global Positioning System and the Mobile Phone System and each of which is adapted to search for stations of a corresponding positioning system; and
control means which fetches search data pertinent to the stations searched by the multiple search means and sends the fetched search data from a transceiver to a position data server, the control means, if a prescribed condition is met after a first search means among the multiple search means has commenced the operation, canceling the operation of the first search means and sending search data fetched by a second search means among the multiple search means from the transceiver to the position data server. - View Dependent Claims (13, 14, 15)
