The present invention carries it " file destination " and is the original transmitting file for the treatment of, the file format of file destination can be forms such as literal, image, sound or film, but the file format of the file destination that the present invention carried is not exceeded with above-mentioned.Wherein, file destination is the file of arbitrary form.
The present invention is shown in " Figure 1A ", it is the known framework that transmits multimedia messages, by transmission end 100 by MMS (Multimedia Message Service), transmission comprises the multimedia messages of a plurality of file destinations, receiving terminal 200 equally can be by the MMS (Multimedia Message Service) receiving multimedia information, and a plurality of file destinations in the multimedia messages are obtained out respectively, so that file destination is sent to receiving terminal 200 by transmission end 100.
Following elder generation illustrates the whole System Operation of each device that the present invention is proposed with the device connection layout of " Figure 1A ".Shown in " Figure 1A ", the present invention contains transmission end 100, receiving terminal 200 and multimedia messaging center 400.Wherein, transmit file destination,, make multimedia messages to be transmitted so 200 of transmission end 100 and receiving terminals also need the multimedia messaging center 400 that MMS (Multimedia Message Service) is provided in order to use multimedia messages.
Storage module 101 is responsible for storing a plurality of file destinations, and storage module 101 stored file destinations are that the user by transmission end 100 is stored in the storage module 101 in advance.Storage module 101 can for built-in in the transmission end 100 memory, the user of transmission end 100 can be after connecting transmission end 100 and computer, upload file destination to the transmission end 100 by computer, the user of transmission end 100 also can directly use downloading object file in transmission end 100 to the Internet.Storage module 101 also can be the storage card of the storage volume of extendible transmission end 100, and the user of transmission end can be stored in file destination in the storage card by devices such as computers in advance, inserts transmission end 100 at the storage card that will store file destination.
File selects module 120 to be responsible for by selecting a plurality of file destinations in the storage module 101.Generally speaking, file selects module 120 can provide the file selection file that the user will be stored in the storage module 101 at the interface to be chosen as file destination.
File merges module 132 to be responsible for selecting module 120 selected file destinations to merge into composition file file, that is to say, if file selects module 120 to select three file destinations such as first file, second file and the 3rd file in regular turn, file merges module 132 and can second file is attached to after second file earlier, the 3rd file is attached to after second file again, so, file merges the merging that module 132 is just finished three files, and the file that merges the back generation is composition file.
Wherein, it is to select the selected file destination of module 120 with the particular order merge file that file merges module 132, and file is when merging module 132 and merging file destinations, the for example above-mentioned file of the producing method of employed particular order selects module 120 to select the order of file destination, or the sequential scheduling mode of random alignment file destination, even select to produce the mode of particular order at random, merge into composition file file is merged module 132 selected file destinations, for example, file merges module 132 and also can at random first file be attached to after second file, and the 3rd file is attached to first file order merging file destination afterwards.But file merges module 132 and merges the employed particular order of file destinations not and as limit.What is particularly worth mentioning is that, be with unfixed order file destination to be merged into composition file because file merges module 132, will make that therefore the content in the composition file is difficult for by identification, and then improve the fail safe of each file when being transmitted.
File merges module 132 to be responsible for that also gauge outfit is set up gauge outfit file that module 136 produced and to append to and merge in the composition file that is produced behind the file destination.Generally speaking, file merges module 132 can append to composition file foremost with the gauge outfit file, but the present invention is not as limit, for example, file merges the least significant end that module 132 also can append to the gauge outfit file composition file, or the ad-hoc location in the gauge outfit file etc.
Gauge outfit is set up module 136 and is responsible for producing the gauge outfit file, gauge outfit file include file is selected the fileinfo of the selected file destination of module 120, for example (following this position that will claim is " deviant " in the position of first of the file size of the file name of file destination, file destination or file destination in composition file, be generally a numeral) etc., but the fileinfo of file destination is not as limit.
Gauge outfit is set up module 136 meetings and one by one the fileinfo of file destination is write the gauge outfit file, that is to say, if file selects module 120 to select two file destinations, then gauge outfit is set up module 136 and can be read fileinfos such as the file name of one of them file destination and file size earlier, read the fileinfo of another one file destination again, set up the gauge outfit file according to the fileinfo of reading afterwards, but gauge outfit is set up module 136 and is set up the mode of gauge outfit file not to exceed, for example, gauge outfit is set up module 136 also can just set up the gauge outfit file behind the fileinfo that reads a file destination, after reading the fileinfo of another file destination again, the fileinfo of reading is write in the gauge outfit file of having set up.
Generally speaking, gauge outfit is set up module 136 can be according to file destination putting in order in composition file, fileinfo with file destination writes in the gauge outfit file in regular turn, make the file destination in the gauge outfit file fileinfo put in order identical with file destination putting in order in composition file.But gauge outfit is set up module 136 and is produced the mode of gauge outfit file not as limit, for example, gauge outfit is set up module 136 and also can be selected module 120 to select the order of file destination by file, or with other random order, the fileinfo of file destination is write in the gauge outfit file, in the case, the fileinfo of the file destination that is write down in the gauge outfit file will comprise the deviant of file destination in composition file.Can unfixed order the fileinfo of file destination be write in the gauge outfit file because gauge outfit is set up module 136, can improve the fail safe of each file when being transmitted in the composition file.
The first file conversion module 150 is responsible for file is merged the package file that the composition file that comprises file destination and gauge outfit file that module 132 produces is converted to the predetermined file form, the predetermined file form of the package file that the present invention carried is the file format of supporting for MMS (Multimedia Message Service), for example, composition file " xmsg.x " is made up of pure words file " info.dat " and two files of binary file " mov.s01 ", therefore composition file " xmsg.x " can not be the text supported of MMS (Multimedia Message Service) or the file format of multimedia file certainly, so when the first file conversion module, 150 predetermined file format system expands the file format of the film shelves that are called " 3gp ", the file format encapsulation composition file " xmsg.x " of the film file of the first file conversion module, 150 meetings " 3gp " by name to expand, that is to say, the first file conversion module 150 can be encapsulated into composition file " xmsg.x " position of writing down photo in the film file of expansion " 3gp " by name, to produce the package file of expansion " 3gp " by name, the file name of package file is " xmsg.x.3gp " or " xmsg.3gp " etc. for example.Wherein, the file name of package file is not exceeded with above-mentioned, the extension name of the package file that the first file conversion module 150 is produced is not also exceeded with " 3gp ", and the extension name of the file format correspondence that other MMS (Multimedia Message Service) is supported can be for used herein.In addition, the mode that the first file conversion module 150 produces package files is not exceeded with the file that composition file is encapsulated as the file format that MMS (Multimedia Message Service) supported yet, alternate manner for example, the extension name " x " of composition file is redefined the extension name of the file format of supporting into MMS (Multimedia Message Service), as " jpg " etc., or the extension name of the file format of supporting in the additional afterwards MMS (Multimedia Message Service) of the file name " xmsg.x " of composition file, make the extension name of composition file be converted into the first file conversion module, 150 default extension name by original extension name, just the file name of package file is converted to " xmsg.x.3gp " or " xmsg.3gp " etc. by " xmsg.x " by the first file conversion module 150.
The package files that first transport module 160 is responsible for the first file conversion module 150 is produced add in the multimedia messages, and send the multimedia messages that comprises the package file that the first file conversion module 150 produced with MMS (Multimedia Message Service).Because multimedia messages need send to receiving terminal 200 by multimedia messaging center 400, so first transport module 160 can be sent to multimedia messaging center 400 with multimedia messages.Wherein, first transport module 160 can be encapsulated into package file in the zone of recording multimedia file in the multimedia messages according to the multimedia messages form.
In addition, transmission end 100 can also comprise the weight allocation module 112 that can add, weight allocation module 112 is responsible for all file destinations to be transmitted and disposes corresponding weight, selects module 120 to determine the selecting sequence of file destination according to the weight corresponding with file destination institute so that file to be provided.Generally speaking, weight allocation module 112 can put in order according to system data, multimedia film, picture, text file etc. and dispose the weight corresponding with file destination, but the mode of weight allocation module 112 configure weights is not as limit.
Comprise in transmission end 100 under the situation of weight allocation module 112, file selection module 120 can be according to the height select target file of weight, after the file size of weight soprano in the non-selected file destination is selected module 120 to select by file, the summation of the file size of the file destination that is selected surpasses the predetermined transmission capacity of multimedia messages, then file selects module 120 can attempt by selecting weight time high file destination in the file that is not selected, after all non-selected files are selected, all can surpass till the predetermined transmission capacity of multimedia messages, use to satisfy allowing first multimedia messages can transmit instantly the expectation of the data of contents at most, but the present invention is not as limit.
Then further specify receiving terminal 200, receiving terminal 200 is similar to transmission end 100, be generally hand-held devices such as mobile phone, PDA, but the present invention is not as limit, all receiving terminals 200 that can use device that MMS (Multimedia Message Service) sends multimedia messages to be carried by the present invention, for example the server 600 in " Figure 1A " also can receive the multimedia messages by transmission end 100.Wherein, receiving terminal 200 comprises second transport module 260, the second file conversion module 270, gauge outfit acquisition module 291 and file acquisition module 295 shown in " Fig. 2 B ".
The second file conversion module 270 is responsible for package file is changed back composition file.Wherein, the mode that the second file conversion module 270 is changed back package file composition file is along with the first file conversion module, 150 conversion composition files are that the mode of package file is different and different, for example, when the first file conversion module 150 is with predetermined file format, as expand the file format of " jpg " by name, when composition file is converted to package file, the second file conversion module 270 can be with the first file conversion module, 150 employed file formats, the file format of expansion just " jpg " by name, read out composition file in the file content by package file, and if the first file conversion module 150 is when being converted to predetermined extension name with the extension name with composition file by original extension name, the second file conversion module 270 can be scheduled to the extension name of package file by the first file conversion module 150 extension name redefines back the original extension name of composition file, for example, with file name is extension name " jpg " deletion of the package file of " xmsg.x.jpg ", or file name is " x " for the extension name of the package file of " xmsg.jpg " is redefined by " jpg ", make the file name of package file be converted to the composition file of " xmsg.x " by the second file conversion module 270.
Obtain out the gauge outfit file in the composition file that gauge outfit acquisition module 291 is responsible for by the second file conversion module 270 package file being gone back to.Because the gauge outfit file is to merge module 132 by the file in the transmission end 100 to be attached in the composition file, and the position of the merging of the file in the transmission end 100 module 132 add list header files is predetermined, so gauge outfit acquisition module 291 can be to preposition, what be generally composition file obtains out the gauge outfit file foremost, but since the gauge outfit file also might be in composition file least significant end, or certain fixed position in the composition file, so, gauge outfit acquisition module 291 just can obtain the gauge outfit file to the least significant end or other the fixed position of composition file.
The fileinfo of the file destination in the gauge outfit file that file acquisition module 295 is responsible for being obtained out according to gauge outfit acquisition module 291 obtains file destination in the composition file that package file is gone back to the second file conversion module 270.For example, when file name that writes down first file and second file in the gauge outfit file in regular turn and file size, file acquisition module 295 can be earlier begun by the next byte of last byte of gauge outfit file, by the byte of obtaining out in the composition file with the file size equal number of first file, the part that is acquired out is first file, afterwards, file acquisition module 295 can continue next byte by last byte that is acquired out and begin to obtain byte with the file size equal number of second file, and the part that is acquired out is second file.
Via above-mentioned modules such as second transport module 260, the second file conversion module 270, gauge outfit acquisition module 291 and file acquisition module 295, receiving terminal 200 can the MMS (Multimedia Message Service) reception comprise the multimedia messages of a plurality of file destinations, and obtains out each file destination more than receiving in the media information.
On practice, because transmission end 100/ receiving terminal 200 may provide the function that transmits multimedia messages and receiving multimedia information simultaneously, so transmission end 100 and receiving terminal 200 more can be combined into an information transceiving device 300, so, information transceiving device 300 can be transmission end 100 or receiving terminal 200 simultaneously, that is to say, information transceiving device 300 can transmit a plurality of file destinations that are incorporated in the multimedia messages, also can obtain out each file destination in the media information more than receiving.
Shown in " Fig. 2 C ", information transceiving device 300 comprises storage module 301, file and selects module 320, file to merge the weight configuration module 312 that module 332, gauge outfit are set up module 336, the first file conversion module 350, transport module 360, the second file conversion module 370, gauge outfit acquisition module 392 and file acquisition module 396 and can be added.Wherein, storage module 301, weight configuration module 312, file is selected module 320, file merges module 332, gauge outfit set up module 336 and the first file conversion module 350 respectively with " Fig. 2 A " in storage module 101, file is selected module 120, file merges module 132, the function that gauge outfit is set up the module 136 and the first file conversion module 150 is identical, the second file conversion module 370,396 of gauge outfit acquisition module 392 and file acquisition modules respectively with " Fig. 2 B " in the second file conversion module 270, the function of gauge outfit acquisition module 291 and file acquisition module 295 is identical, so repeat no more.And transport module 360 has also comprised first transport module 160 in " Fig. 2 A " and the function of second transport module 260 in " Fig. 2 B " simultaneously, so also no longer repeat specification.
Then explain orally operation system of the present invention and method with an embodiment, and please refer to " Fig. 3 " the present invention carried transmit the method flow diagram of a plurality of files and the schematic diagram of " Fig. 4 " simultaneously with MMS (Multimedia Message Service).
In the present embodiment, suppose that transmission end 100 and receiving terminal 200 all are to carry out the mobile phone that the present invention is arranged, but do not exceed with mobile phone with receiving terminal 200 in the transmission end 100 that the present invention carried.
Sending file name when the conveyer tendency to develop is " data.zip ", when file destination such as " xmsg.dat " and " song.mp3 " is given the recipient, if conveyer is desired to transmit with its employed mobile phone (transmission end 100), then select to be stored in " data.zip " in the storage module 101 of transmission end 100 at the operation interface of conveyer by mobile phone, behind three file destinations such as " xmsg.dat " and " song.mp3 ", file in the transmission end 100 selects module 120 to select " data.zip " with the order of conveyer select target file or putting in order of the file name of selecteed file destination, file destination (step 520) such as " xmsg.dat " and " song.mp3 ".
After file in transmission end 100 selected module 120 to select file destination (step 520), the file of transmission end 100 merges module 132 can merge into composition file (step 534) with file destination with particular order.That is to say, the file of present embodiment merges module 132 can be with file destination " song.mp3 ", file destination " data.zip " and file destination " xmsg.dat " are merged into the composition file " package.x " that extension name is fixed as " x ", suppose that it is with putting in order at random that file merges module 132, earlier file destination is arranged as " xmsg.dat ", " song.mp3 ", " data.zip " (step 532), in regular turn file destination " song.mp3 " is incorporated in file destination " xmsg.dat " rear again, and file destination " data.zip " is incorporated in file destination " song.mp3 " rear, so, in the composition file " package.x " that after merging three file destinations, is produced, be file destination " xmsg.dat " in regular turn, file destination " song.mp3 " and file destination " data.zip ".Wherein, file merges order that module 132 merges file destinations and does not exceed with putting in order at random.
After the file merging module 132 of transmission end 100 was merged into composition file (step 534) with particular order with file destination, the gauge outfit of transmission end 100 is set up module 136 can produce gauge outfit files (step 536).Suppose in the present embodiment, gauge outfit is set up module 136 can be according to the order of each file destination in composition file " package.x ", the order of " xmsg.dat ", " song.mp3 " and " data.zip " just, in regular turn fileinfos (710,720,730) such as the file name of file destination " xmsg.dat ", " song.mp3 " and " data.zip " and file size are produced gauge outfit file 700, shown in " Fig. 5 A ".Wherein, fileinfo 710 is with the file name of 16 byte records file destinations " xmsg.dat ", and after file name with the file size of 4 byte records file destinations " xmsg.dat ", same, fileinfo 720 and fileinfo 730 are also respectively with file name/file size of 16 byte/4 byte records file destination " song.mp3 " and " data.zip ", but the gauge outfit file that the present invention carried is not as limit.
On practice, the file of transmission end 100 merges gauge outfit that module 132 merges into composition file (step 534) and transmission end 100 with file destination and sets up the process that module 136 produces gauge outfit files (step 536) and can together be performed, for example, when file merges module 132 merging file destinations " xmsg.dat " and file destination " song.mp3 ", gauge outfit is set up module 136 and also can be set up in the gauge outfit file 700 with fileinfos 710 such as the file name of file destination " xmsg.dat " and file sizes simultaneously, and fileinfos such as the file name of file destination " song.mp3 " and file size 720 are added gauge outfit files 700, then, when file merged module 132 and merges the composition file that comprises file destination " xmsg.dat " and file destination " song.mp3 " and file destination " data.zip ", gauge outfit is set up module 136 also can add gauge outfit files 700 with fileinfos 730 such as the file name of file destination " data.zip " and file sizes.
