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.

This invention is to enable transfer of a right to speak in an audio teleconference in view of usability. In this invention, a PoC server is introduced to achieve new functions, such as transfer of the right to speak, reservation to acquire the right to speak, and deprivation of the right to speak. The PoC server has a teleconference presence manager, a teleconference manager, and a teleconference audio communication manager. The right to speak is managed in a presence data storage of the teleconference presence manager. The teleconference presence manager directly manages the presence data storage, but the teleconference manager manages transfer of the right to speak. In addition, the teleconference manager manages reservation of the right to speak by a storage for a reservation list of the right to speak. The teleconference audio communication manager carries out routing of audio data. At that time, only audio data received from a user holding the right to speak is transferred.
