Abstract

A communication apparatus according to the present invention is connected with other centers through a network, and the apparatus includes one or a plurality of center boxes addressed to the other centers, and one or a plurality of local boxes addressed to the locals connected to the center itself. The present communication apparatus stores data addressed to another center and data addressed to a local connected to the other center from a local connected to the apparatus itself into its center box addressed to the other center, and the apparatus stores data addressed to a local connected to the apparatus itself, the data having been transmitted from another center, into its local box addressed to the local.

Claims

1. A communication system including centers and locals connected to respective centers, wherein each of the centers includes:

one or a plurality of center boxes addressed to other centers;

one or a plurality of local boxes addressed to locals connected to said center itself;

center box storing means for storing data addressed to another center and data addressed to a local connected to said other center into a center box addressed to said other center; and

local box storing means for storing data addressed to a local connected to said center itself, the data being transmitted from another center, into a local box addressed to said local, and

wherein each of said local includes;

transmission means for transmitting data addressed to another center or another local to a center to which said local itself is connected; and

reception means for receiving data addressed to said local itself from a local box addressed to said local itself in said center to which said local itself is connected.

2. A communication system according to claim 1, wherein each of the centers further comprising:

reception means for receiving data from another center or another local; and

transmission means for transmitting data stored in a center box to another center corresponding to said center box.

3. A communication system according to claim 1, wherein, when each of said centers receives a plurality of data, a plurality of addresses or a plurality of dates as one file, said center classifies the received data, the received addresses or the received dates to store them into a center box or a local box corresponding to the data, the addresses or the dates.

4. A communication system according to claim 1, wherein transmission means of said center automatically re-transmits data in case of a communication error.

5. A communication system according to claim 4, wherein said transmission means of said center performs data transmission by Connect Direct.

6. A communication system according to claim 4, wherein said transmission means and said reception means of said local can select a communication protocol to perform communication.

7. A communication system according to claim 6, wherein said transmission means and said reception means of said local can select at least Correct Direct or FTP to perform communication.

8. A communication system according to claim 1, wherein said center includes means for supplying communication information of data or information of communication data in response to a request from an outside.

9. A communication system according to claim 2, wherein said center includes means for transforming received data addressed to a local to data by a character code corresponding to said local.

10. A communication apparatus for a center connected with other centers through a network and connected with locals, said apparatus comprising:

one or a plurality of center boxes addressed to said other centers;

one or a plurality of local boxes addressed to said locals connected to said center itself;

center box storing means for storing data addressed to another center and data addressed to a local connected to said other center into a center box addressed to said other center; and

local box storing means for storing data addressed to a local connected to said center itself, the data having been transmitted from another center, into a local box addressed to said local.

11. A communication apparatus according to claim 10, wherein said apparatus further comprising:

reception means for receiving data from another center or another local; and

transmission means for transmitting data stored in a center box to another center corresponding to said center box.

12. A communication apparatus according to claim 10, wherein, when said center box storing means and said local box storing means receive a plurality of data, a plurality of addresses or a plurality of dates as one file, said center box storing means and said local box storing means classify the received data, the received addresses or the received dates to store them into a center box or a local box corresponding to the data, the addresses or the dates.

13. A communication apparatus according to claim 10, wherein transmission means of said apparatus automatically re-transmits data in case of a communication error.

14. A communication apparatus according to claim 13, wherein said transmission means of said center performs data transmission by Connect Direct.

15. A communication apparatus according to claim 10, said apparatus further comprising means for supplying communication information of data or information of communication data in response to a request from an outside.

16. A communication apparatus according to claim 11, said apparatus further comprising means for transforming received data addressed to a local to data by a character code corresponding to said local.

17. A communication method of a center connected with other centers through a network and connected with locals, said method comprising:

a reception step of receiving data from another center or another local;

a center box storing step of storing data addressed to another center and data addressed to a local connected to said other center into a center box addressed to said other center; and

a local box storing step of storing data addressed to a local connected to said center itself, the data having been transmitted from another center, into a local box addressed to said local.

18. A recording medium capable of being read by a computer, said medium recording a program of communication performed by a center connected with other centers through a network and connected with a plurality of locals, said program making said computer execute procedures comprising:

a reception procedure of receiving data from another center or another local;

a center box storing procedure of storing data addressed to another center and data addressed to a local connected to said other center into a center box addressed to said other center; and

a local box storing procedure of storing data addressed to a local connected to said center itself, the data having been transmitted from another center, into a local box addressed to said local.
