<p>PURPOSE:To realize high speed and low connection cost communication by combining a low cost low speed communication system always connected with a high connection cost high speed communication system. CONSTITUTION:A terminal equipment 1 is provided with two types of communication system: the low cost low speed communication system and the high connection cost high speed communication system. A low speed communication control means 11 performs the communication by means of the low sped communication system; while a high speed communication control means 12 perform the communication by means of the high speed communication system. A communication data amount measurement means 13 measures the amount of communication data per a prescribed period of time, and a line control means 14 connects and disconnects the communication by means of the high speed communication system corresponding to the amount of communication data.</p> |
