<p>If it is judged that audio information is being transmitted when transmitting position information by a control unit, a radio device of a mobile station side embeds the position information in an empty packet of audio information being transmitted by the control unit and causes a radio communication unit to transmit the packet to a radio device of a base station side. Thus, it is possible to perform accurate position management even when an audio communication is present.</p> |
