An appropriate attention can be made when a communication connection recovers from its interruption. When a client terminal (2) requests an attribute information provision server (7) for and receives therefrom a content attribute file (47) corresponding to content data stored in a hard disc, and if a communication connection is interrupted during such reception and thereafter recovers from its interruption, the client terminal (2) requests a portal server (4) for billing status notification information, and then billing status notification screens (15,16) transmitted in response to that request are transmitted back. In this way, when the communication connection has recovered from its interruption after it was interrupted during reception of the content attribute file (47), the billing status notification information can be used to notify whether a billing processing has been completed or not, thereby making an appropriate attention at the recovery of the communication connection from its interruption. |
