Data communication apparatus and method
First Claim
1. A data processing apparatus which performs a data process via a local area network (LAN) and a communication line other than the LAN, comprising:
- reception means for receiving a data designated to a plurality of receivers, from a transmission side via the communication line;
notification means for notifying the plurality of receivers on the LAN that said reception means received the data;
transmission means for transmitting information representing a notification result by said notification means, to the transmission side from which the data received by said reception means was transmitted via the communication line;
setting means for setting a time to permit a transmission of the information representing the notification result by said notification means;
determining means for determining whether or not the time set by said setting means has been reached; and
control means for causing said transmission means to transmit the information representing the notification result by said notification means via the communication line, in a case where said determining means determines that the time set by said setting means has been reached, wherein said control means causes said transmission means to transmit the information concerning receivers to which the notification by said notification means was successful among the plurality of receivers designated by the transmission side until it is determined by said determining means that the time set by said setting means has been reached.

Abstract
The present invention provides a data processing apparatus which performs a data process via a LAN and a communication line other than the LAN comprises reception means for receiving data from a transmission side via the communication line notification means for notifying that the reception means received the data, to a plurality of receivers on the LAN transmission means for transmitting information representing a notification result by the notification means, to the transmission side timer means for performing a time count and control means for causing the transmission means to start the transmission, when it is judged by the timer means that a predetermined period of time is elapsed, so that it can be easily notified to the transmission side whether or not the data reception was notified to terminals on the LAN.

4. A control method of a data processing apparatus which performs a data process via a local area network (LAN) and a communication line other than the LAN, said method comprising:
-
a reception step of receiving data designated to a plurality of receivers, from a transmission side via the communication line; a notification step of notifying the plurality of receivers on the LAN that the data is received in said reception step; a transmission step of a transmitting information representing a notification result in said notification step, to the transmission side from which the data received in said reception step was transmitted via the communication line; a setting step of setting a time to permit a transmission of the information representing the notification result in said notification step; a determining step of determining whether or not the time set in said setting step has been reached; and a control step of causing said transmission step to transmit the information representing the notification result in said notification step via the communication line, in a case where said determining step determines that the time set in said setting step has been reached, wherein said control step causes said transmission step to transmit the information concerning receivers to which the notification in said notification step was successful among the plurality of receivers designated by the transmission side until it is determined in said determining step that the time set in said setting step has been reached.

5. A computer-readable program to be used by data processing apparatus which performs a data processing via a local area network (LAN) and a communication line other than the LAN, said apparatus comprising:
-
reception means for receiving data designated to a plurality of receivers, from a transmission side via the communication line; notification means for notifying the plurality of receivers on the LAN that said reception means received the data; transmission means for transmitting information representing a notification result by said notification means, to the transmission side from which the data received by said reception means was transmitted via the communication line; setting means for setting a time to permit a transmission of the information representing the notification result by said notification means; determining means for determining whether or not the time set by said setting means has been reached; and control means for causing said transmission means to transmit the information representing the notification result by said notification means via the communication line, in a case where said determining means determines that the time set by said setting means has been reached, wherein said control means causes said transmission means to transmit the information concerning receivers to which the notification by said notification means was successful among the plurality of receivers designated by the transmission side until it is determined by said determining means that the time set by said setting means has been reached.
