Fig. 1 is the flow chart of safe storage multimedia message in the method for the invention.
Embodiment
Technical scheme of the present invention is further illustrated below in conjunction with drawings and Examples.
First introduce the storage organization of multimedia message, be made up of the index file (table 1) of mailbox and MMS content file (table 2):
Table 1:
Table 2:
Show the flow process 100 of safe storage multimedia message in the present invention see Fig. 1, Fig. 1, comprise the following steps:
101, operational processes is carried out to the MMS content file stored in described mobile email.The operation that operational processes comprises increase, deletes and change.
First can store the content of (increase, delete, change) multimedia message, such as multimedia message n; For deletion action, first delete MMS content file itself; Increase operation is first preserved to the content of multimedia message; For change multimedia message, first upgrade multimedia message files itself.
102, back up the mailbox index file in described step 101 corresponding to multimedia message content file, write described mobile phone memory bank.
In order to ensure that the mailbox index file backed up can be updated on module (FLASH, or T card) at once, the Sync that calls of display or implicit expression is needed to operate.
103, after completing the operational processes of described step 101, the mailbox index file corresponding to described MMS content file is upgraded.
Upgrade described mailbox index file, specifically refer to and recalculate index file length and School Affairs and by its writing in files.For ease of detecting file availability and accelerating index file access, the index of each multimedia message can adopt regular length, and such as file name is 2m byte.The calculating of School Affairs can carry out complement of one's summation simply by every 16 of each multimedia message indexing head file name (regular length).Namely n multimedia message, each length is m 16 complements of one's summation.

If be interrupted in step 102 backup procedure, can identify by detecting backup mailbox index file during start next time.At this moment can, with the file of original index, when producing the situation in (ii), the way that (ii) is the same be taked to upgrade index file; When producing the situation of (iii), (iii) the same way is taked to process.Such as: when not finding the mailbox index file of described backup after boots, then read former mailbox index file and back up; When finding the mailbox index file of described backup after boots, then upgrade former mailbox index file.
If step 103 upgrade mailbox index file process in be interrupted, next time start time can detect mailbox index file do not exist or file size and check code incorrect.Recover with the mailbox index file of backup, and delete the file of backup.So also can produce the situation in (ii) or (iii), so take the way that (ii) or (iii) is the same to upgrade mailbox index file.Such as: when detect after boots index file do not exist or file size and check code incorrect, then recover with the mailbox index file of described backup; When detecting after boots that index file exists, then upgrade the mailbox index file corresponding to described MMS content file.
If be interrupted at step 104, next start can be checked through mailbox index file and backup mailbox index file file simultaneously.Check the School Affairs of two files and length field, be preferential with the mailbox index file after upgrading in all effective situation of two files, delete and back up mailbox index file.
The embodiment of specifically deleting multimedia message below by one sets forth the inventive method further:
Such as to delete multimedia message MMSn in multimedia message inbox, suppose that index file is called INBOX.BIN.
Delete procedure is as follows:
(1) find the filename that in index file, in INBOX.BIN, MMSn is corresponding, delete this file;
(2) back up INBOX.BIN, generate INBOX_BK.BIN and write module (FLASH, T card);
(3) in INBOX.BIN, remove the index information of MMSn, upgrade multimedia message number, index file length, recalculates School Affairs, and writing in files;
(4) the backup file INBOX_BK.BIN in delete step (2).
When after mobile phone power down, during boots, during access multimedia message, recovery process is as follows:
(1) check that inbox is with or without index backup file INBOX_BK.BIN, and index file INBOX.BIN;
If i () backup file INBOX_BK.BIN exists, index file INBOX.BIN does not exist then with INBOX_BK.BIN recovery, and deletes INBOX_BK.BIN;
(ii) if both exist simultaneously, if then checked their validity by length and School Affairs. INBOX.BIN is effective, deletes INBOX_BK.BIN; Otherwise recover INBOX.BIN with INBOX_BK.BIN, and delete INBOX_BK.BIN;
(iii) if INBOX.BIN exists, backup file does not exist, and shows the abnormal problem not having to delete.
(2) open file MMSn time:
I () MMSn file does not exist, then upgrade INBOX.BIN index file (remove the index entry of MMSn, upgrade multimedia message number, file size, recalculates School Affairs).
(ii) MMSn file exists but error in data, optionally can upgrade INBOX.BIN index file (remove the index entry of MMSn, upgrade multimedia message number, file size, recalculates School Affairs).
