Research server 4 transmits to moving status search server 3 a request for providing moving status information containing a conditional expression, designating attributes of users to be researched. Moving status search server 3 extracts users having user attribute information (information such as address, occupation or the like, of each user) matching the conditional expression and obtains location information from mobile stations 1 which the users possess. In this way, moving status search server 3 generates moving status information on the basis of location information of users having user attribute information matching the conditional expression, and transmits the generated moving status information to research server 4.
