Abstract

The present disclosure relates to a pre-5th-generation (5G) or 5G communication system to be provided for supporting higher data rates beyond 4th-generation (4G) communication system such as a long term evolution (LTE). A method for uploading data by a station (STA) in a mobile communication system supporting a plurality of radio access interfaces (RAIs) is provided. The method includes, upon detecting that there is content to be uploaded, determining whether a first RAI among the plurality of RAIs is available, and when the first RAI is available, transmitting a header message including information related to the content and a body message including at least one of a plurality of segments which are generated based on the content to a proxy server through the first RAI to upload the at least one of the plurality of segments to an original server.

Claims

1. A method for uploading data by a station (STA) in a mobile communication system supporting a plurality of radio access interfaces (RAIs), the method comprising:

upon detecting that there is content to be uploaded, determining whether a first RAI among the plurality of RAIs is available;

when the first RAI is available, transmitting a header message including information related to the content and a body message including at least one of a plurality of segments which are generated based on the content to a proxy server through the first RAI to upload the at least one of the plurality of segments to an original server.

2. The method of claim 1, further comprising:

stopping the transmitting of the body message upon detecting that the first RAI is unavailable while transmitting the body message.

3. The method of claim 2, further comprising:

detecting that the first RAI is available after stopping transmitting the body message; and

retransmitting the body message through the first RAI.

4. The method of claim 1, wherein the transmitting of the header message and the body message to the proxy server through the first RAI to upload the at least one of the plurality of segments to the original server comprises:

for each of the plurality of segments, transmitting a header message including information related to the content and a body message including a corresponding segment to the proxy server through the first RAI to upload the corresponding segment to the original server.

5. The method of claim 1, wherein a size of each of the plurality of segments is fixed or variable.

6. The method of claim 5, wherein, when the size of each of the plurality of segments is variable, the size of each of the plurality of segments is set to a size which is generated by adding a segment size currently set and a preset step size whenever segment transmission to the proxy server is successful.

7. The method of claim 5, wherein, when the size of each of the plurality of segments is variable, the size of each of the plurality of segments is set to a size which is generated by multiplying a segment size currently set and a preset value whenever segment transmission to the proxy server is successful.

8. The method of claim 5, wherein, when the size of each of the plurality of segments is variable, the size of each of the plurality of segments is set to a size less than a preset value.

9. A method for uploading data by a station (STA) in a mobile communication system supporting a plurality of radio access interfaces (RAIs), the method comprising:

detecting that there is content to be uploaded; and

transmitting a header message including information related to the content and a body message including at least one of a plurality of segments which are generated based on the content to a proxy server through each of the plurality of RAIs to upload the at least one of the plurality of segments to an original server.

10. The method of claim 9, further comprising:

stopping transmitting the body message through a first RAI among the plurality of RAIs upon detecting that the first RAI among the plurality of RAIs is unavailable while transmitting the body message.

11. The method of claim 10, further comprising:

retransmitting the body message through one of the plurality of RAIs except for the first RAI among the plurality of RAIs after stopping transmitting the body message through the first RAI.

12. The method of claim 9, wherein the transmitting of the header message and the body message to the proxy server through each of the plurality of RAIs to upload the at least one of the plurality of segments to the original server comprises:

for each of the plurality of segments, transmitting a header message including information related to the content and a body message including a corresponding segment to the proxy server through each of the plurality of RAIs to upload the corresponding segment to the original server.

13. The method of claim 9, wherein a size of each of the plurality of segments is fixed or variable.

14. The method of claim 13, wherein, when the size of each of the plurality of segments is variable, the size of each of the plurality of segments is set to a size which is generated by adding a segment size currently set and a preset step size whenever segment transmission to the proxy server is successful.

15. The method of claim 13, wherein, when the size of each of the plurality of segments is variable, the size of each of the plurality of segments is set to a size which is generated by multiplying a segment size currently set and a preset value whenever segment transmission to the proxy server is successful.

16. The method of claim 13, wherein, when the size of each of the plurality of segments is variable, the size of each of the plurality of segments is set to a size less than a preset value.

17. A method for supporting data upload of a station (STA) by a proxy server in a mobile communication system supporting a plurality of radio access interfaces (RAIs), the method comprising:

receiving a header message including information related to content to be uploaded by the STA to an original server and a body message including at least one of a plurality of segments which are generated based on the content,

wherein the header message and the body message are transmitted through at least one of the plurality of RAIs.

18. The method of claim 17, wherein, for each of the plurality of segments, a header message including information related to the content and a body message including a corresponding segment are received.

19. The method of claim 17, wherein a size of each of the plurality of segments is fixed or variable.

20. The method of claim 17, further comprising:

detecting that reception for the plurality of segments has been completed; and

generating the content by reassembling the plurality of segments and transmitting the header message and the body message including the content to the original server.
