Abstract
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.
