Abstract

A method for resuming data transmission in a data transmission system including multiple information processing units and at least one mobile device, the multiple information processing units and the mobile device each including a wireless communication component, the method includes: transmitting data, by a first one of the multiple information processing units, to the mobile device; recording a transmission status of the mobile device, the transmission status including information regarding an unfinished data transmission by the first information processing unit to the mobile device; and resuming transmitting data relating to the unfinished data transmission, by a second one of the multiple information processing units, to the mobile device based on the recorded transmission status.

Claims

1. A method for resuming data transmission in a data transmission system including multiple information processing units and at least one mobile device, the multiple information processing units and the mobile device each including a wireless communication component, the method comprising:

transmitting data, by a first one of the multiple information processing units, to the mobile device;

recording a transmission status of the mobile device, the transmission status including information regarding an unfinished data transmission by the first information processing unit to the mobile device; and

resuming transmitting data relating to the unfinished data transmission, by a second one of the multiple information processing units, to the mobile device based on the recorded transmission status.

2. The method of claim 1, wherein the transmitting data by the first information processing unit comprises:

detecting the mobile device; and

transmitting the data to the mobile device.

3. The method of claim 1, wherein the transmitting data by the first information processing unit comprises:

detecting the mobile device;

receiving a request for data from the mobile device; and

transmitting the requested data to the mobile device.

4. The method of claim 1, wherein the transmitting data by the first information processing unit further comprises authenticating the mobile device.

5. The method of claim 1, wherein the recording comprises recording by the first information processing unit of the transmission status.

6. The method of claim 1, wherein the recording comprises recording by the mobile device of the transmission status.

7. The method of claim 1, wherein the recording comprises the first information processing unit sending the transmission status to others of the multiple information processing units.

8. The method of claim 1, wherein the recording comprises sending the data relating to the unfinished data transmission to others of the multiple information processing units.

9. The method of claim 8, wherein the sending comprises predicting ones of the multiple information processing units to which the data relating to the unfinished data transmission is to be sent.

10. The method of claim 1, wherein recording the transmission status comprises recording:

an ID of the wireless communication component of the mobile device;

a number of data files relating to the unfinished data transmission; and

breakpoint addresses in the data files;

wherein data after the breakpoint addresses in the data files has not been transmitted to the mobile device.

11. The method of claim 10, wherein the data files are in textual, video, audio, or graphic formats.

12. A method for resuming data transmission in a data transmission system including a server, multiple information processing units, and at least one mobile device, the multiple information processing units and the mobile device each including a wireless communication component, the method comprising:

transmitting data, by the server, to the multiple information processing units;

transmitting data, by a first one of the multiple information processing units, to the mobile device;

recording a transmission status of the mobile device, the transmission status including information regarding an unfinished data transmission by the first information processing unit to the mobile device; and

resuming transmitting data relating to the unfinished data transmission, by a second one of the multiple information processing units, to the mobile device based on the recorded transmission status.

13. The method of claim 12, wherein the transmitting data by the first information processing unit comprises:

detecting the mobile device; and

transmitting the data to the mobile device.

14. The method of claim 12, wherein the transmitting data by the first information processing unit comprises:

detecting the mobile device;

receiving a request for data from the mobile device; and

transmitting the requested data to the mobile device.

15. The method of claim 12, wherein the transmitting data by the first information processing unit further comprises authenticating the mobile device.

16. The method of claim 12, wherein the recording comprises recording by the server of the transmission status.

17. The method of claim 12, wherein the recording comprises recording by the first information processing unit of the transmission status.

18. The method of claim 12, wherein the recording comprises recording by the mobile device of the transmission status.

19. The method of claim 12, wherein the recording comprises the server sending the transmission status to others of the multiple information processing units.

20. The method of claim 12, wherein the recording comprises the first information processing unit sending the transmission status to others of the multiple information processing units.

21. The method of claim 12, wherein the recording comprises the server sending the data relating to the unfinished data transmission to ones of the multiple information processing units.

22. The method of claim 21, wherein the sending comprises predicting the ones of the multiple information processing units to which the data relating to the unfinished data transmission is to be sent.

23. The method of claim 12, wherein recording the transmission status comprises recording:

an ID of the wireless communication component;

a number of data files corresponding to the unfinished data transmission; and

breakpoint addresses in the data files;

wherein data after the breakpoint addresses in the data files has not been transmitted to the mobile device.

24. The method of claim 23, wherein the data files are in textual, video, audio, or graphic formats.

25. A data transmission system, comprising:

multiple information processing units; and

at least one mobile device configured to wirelessly receive data from the multiple information processing units;

wherein a first one of the multiple information processing units is configured to perform a resumable data transmission to the mobile device, such that a second one of the multiple information processing units may resume an unfinished data transmission by the first information processing unit.

26. The system of claim 25, further comprising a server, the server being configured to store data and transmit the stored data to the multiple information processing units.

27. The system of claim 25, wherein the multiple information processing units are connected with wired or wireless networks.

28. The system of claim 25, wherein one of the multiple information processing units comprises a memory device configured to store data.

29. The system of claim 28, wherein the one of the multiple information processing units further comprises a media device configured to broadcast contents of the stored data.

30. The system of claim 28, wherein the one of the multiple information processing units is configured to authenticate the mobile device.
