ABSTRACT:
The object is to enable suppression of an excessive number of changes in assignment of a server in charge of communication in response to movement of a terminal. A position-information acquisition unit in a computer acquires information on the position of a mobile terminal as a candidate for a destination of information provision. Then, a zone determination unit determines whether or not the mobile terminal is in a coverage zone or a margin zone on the basis of the information on the position. An information provision unit starts the information provision to the mobile terminal when the mobile terminal enters the coverage zone, and ends the information provision to the mobile terminal when the mobile terminal goes out of the margin zone.
