Abstract

The present invention discloses a method for upgrading a software version, which is applied to a mobile terminal, and the method comprises: a mobile terminal receiving a losslessly-compressed update file of a software version, and decompressing and restoring the update file; and the mobile terminal performing writing operation after the update file is decompressed and restored. The present invention further provides a mobile terminal and a system based on the method. Through the present solution, the update file of the software version of the mobile terminal is losslessly compressed by a lossless compression algorithm to solve the problems of very long downloading time and low downloading direct through rate in the related arts where the update file of the software version is directly downloaded and upgraded, therefore, the data transmission volume is reduced, the upgrade time of the mobile terminal is effectively reduced, and the mobile terminal can complete the upgrade process fast and securely, thus the upgrading and downloading efficiency is improved.

Claims

1-11. -11. (canceled)

12. A method for upgrading a software version which is applied to a mobile terminal, the method comprising:

a mobile terminal receiving at least one losslessly-compressed update file of a software version, and decompressing and restoring the at least one update file; and

the mobile terminal performing writing operation after the at least one update file is decompressed and restored.

13. The method according to claim 12, wherein the at least one update file comprises multiple update files of the software version, and prior to the mobile terminal receiving the losslessly-compressed file, the method further comprises:

losslessly compressing and saving the update files one by one; and

determining that all the update files have been losslessly compressed.

14. The method according to claim 13, wherein, before compressing and saving the update files one by one, the method further comprises:

judging whether each update file of the software version needs to be losslessly compressed.

15. The method according to claim 14, wherein, prior to the mobile terminal decompressing and restoring at least one update file, the method further comprises:

the mobile terminal judging whether the received at least one update file needs to be decompressed and restored.

16. The method according to claim 15, wherein, subsequent to the mobile terminal judging whether the received at least one update file needs to be decompressed and restored, the method further comprises:

the mobile terminal directly writing at least one update file which does not need to be decompressed and restored.

17. The method according to claim 12, wherein the at least one update file of the software version is losslessly compressed by the following algorithm:

Run-Length Encoding (RLE) lossless compression algorithm.

18. The method according to claim 13, wherein the update file of the software version is losslessly compressed by the following algorithm:

Run-Length Encoding (RLE) lossless compression algorithm.

19. The method according to claim 14, wherein the update file of the software version is losslessly compressed by the following algorithm:

Run-Length Encoding (RLE) lossless compression algorithm.

20. The method according to claim 15, wherein the update file of the software version is losslessly compressed by the following algorithm:

Run-Length Encoding (RLE) lossless compression algorithm.

21. The method according to claim 16, wherein the update file of the software version is losslessly compressed by the following algorithm:

Run-Length Encoding (RLE) lossless compression algorithm.

22. A mobile terminal, comprising:

a receiving module, configured to receive at least one losslessly-compressed update file of a software version;

a decompression module, configured to decompress and restore the at least one losslessly-compressed update file, and

a writing module, configured to write the at least one update file decompressed and restored by the decompression module.

23. A system for upgrading a software version, the system comprising:

a lossless compression device and the mobile terminal according to claim 22, wherein

the lossless compression device is configured to losslessly compress at least one update file of a software version and send the losslessly-compressed at least one update file to the mobile terminal.

24. The system according to claim 23, wherein the at least one update file comprises multiple update files of the software version, and wherein the lossless compression device comprises:

a compression module, configured to losslessly compress and save the update files one by one and determine that all the update files have been losslessly compressed; and

a sending module, configured to send the losslessly-compressed update files to the mobile terminal.

25. The system according to claim 24, wherein the lossless compression device further comprises:

a first judging module, configured to judge whether each update file of the software version needs to be losslessly compressed; and

the mobile terminal further comprises;

a second judging module, configured to judge whether at least one received update file needs to be decompressed and restored.

26. The system according to claim 23, wherein the lossless compression device is configured to losslessly compress the at least one update file of the software version by RLE lossless compression algorithm.

27. The system according to claim 24, wherein the lossless compression device is configured to losslessly compress the update file of the software version by RLE lossless compression algorithm.

28. The system according to claim 25, wherein the lossless compression device is configured to losslessly compress the update file of the software version by RLE lossless compression algorithm.
