1. An active data collection mode control system that reduces crowd-sourcing signal data collection required for fingerprint database (FPDB) maintenance, the system comprising:
a mobile device configured to support a survey mode, a localization mode, and a crowd-sourcing mode; and
a server configured to:
receive data from the mobile device;
generate and update an FPDB from the received data;
control a data collection mode of the mobile device according to a performance change of an indoor localization system;
evaluate a change measurement value using the FPDB and crowd-sourcing data; and
cluster a cell, in which the change measurement value is higher than a predefined threshold, into an area that requires crowd-sourcing data for update.
