Abstract
A positional information service server selects a measuring system most suitable for measuring quality conditions received from a terminal requesting measurement when able to measure position of a designated mobile unit to be measured by a plurality of measuring systems. The positional information service server acquires the positional information of the mobile unit based on the selected measuring system, and transmits it to the terminal designated as the one to be notified.
