Embodiment
For enabling above-mentioned purpose of the present invention, feature and advantage become apparent more, and below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation.
The present invention relates to transfer files between two equipment, the equipment of indication of the present invention can be comprise the equipment that mobile phone, PC, TV, flat board etc. can realize communication connection, also can be two modules in equipment.As shown in Figure 1, show the schematic diagram of transfer files between the present invention's two equipment, mark 11 describes the direction of file transfer, wherein real segment represents from device A and is sent to equipment B, phantom line segments represents from equipment B and is sent to device A, and mark 12 describes the device role determined according to paper conveyance direction, when file is sent to equipment B from device A, device A is as transmitting terminal, and equipment B is as receiving terminal; When file is sent to device A from equipment B, equipment B is as transmitting terminal, and device A is as receiving terminal.No matter be device A or equipment B, in the application of reality, all possibility, also can as a side of passive reception file data as the side initiatively sending file.In the following description, the equipment sending file is also referred to as transmitting terminal, and the equipment receiving file is also referred to as receiving terminal.
embodiment one:
With reference to Fig. 2, show a kind of document transmission method of the embodiment of the present invention one, the method specifically can comprise the following steps:
Step 201, obtains at least one file to be transmitted.
In the embodiment of the present invention, file to be transmitted comprises word, picture, video or control information.For the file that each is determined, if equipment B will be passed to from device A, application person will pre-set the priority attribute of file to be transmitted before transmitting, the present invention proposes the concept of File header information for this reason, File header information is relied on to identify the association attributes of this file to be transmitted, comprise file size to be transmitted and precedence information, by this File header information, make the priority set can be informed to the split cells (can describe in detail) of lower one deck below.File to be transmitted adds the schematic diagram of File header information as shown in Figure 3.Can see that the data of file to be transmitted remain unchanged, only in the original position of file to be transmitted, the field of the description document size that affix is extra and File Privilege, can comprise file in addition the need of information such as verifications.
Particularly, to the setting of priority, according to the actual demand of user, 1 ~ P(P>1 can be preset) individual rank, the priority setting 1 correspondence is the highest, and numerical value is larger, and its priority is lower.
Described file declustering to be transmitted is at least one subfile by step 202, and each subfile carries the identical priority of the to be transmitted file corresponding with it.
For convenience of splitting, the maximum transfer size M of setting subfile, maximum transfer size M is equivalent to a data unit, for each file to be transmitted, all repartitions file based on this data unit.Each new data generated based on data unit is referred to as subfile.
Suppose that file size to be transmitted is K, rounding up to K/M obtains the number N that file division to be transmitted is subfile.Particularly, if K can be divided exactly by M, then n=K/M; If K can not be divided exactly by M, then n=K/M+1, the size of last subfile is decided by the remainder of whole file size to be transmitted divided by the maximum transfer size of subfile.
The numerical value of maximum transfer size M can be determined according to the performance of platform reality, in actual mechanical process, in conjunction with the size of expection file to be transmitted, and the different numerical value of testing setup is on the impact of transmission speed, the present embodiment adopts 1Mbytes, but does not limit, also 64Kbytes can be adopted, the numerical value such as 256Kbytes, 512Kbytes, 2Mbytes.
In order to the information making each subfile can both carry priority, now need the subfile header extra to subfile affix, comprise mark, the number of subfile, the sequence number of subfile of corresponding file to be transmitted, and the precedence information of subfile, as Fig. 4, show the schematic diagram that file declustering to be transmitted becomes N number of subfile.In figure, the mark of the file to be transmitted in the subfile header of subfile 1, for representing which file declustering to be transmitted is subfile 1 be by.The number of subfile for representing that transfer files is split as total number N of subfile, the sequence number of subfile for represent subfile 1 be in subfile sequence which, the precedence information of subfile 1 inherits the priority of file to be transmitted.
Step 203, according to priority sequential delivery subfile from high to low; If the priority of the file to be transmitted of the priority ratio current transmission of the new file to be transmitted obtained is high, then suspends the transmitting procedure of current file to be transmitted, record the subfile transmitted in described current file to be transmitted; And according to new priority orders transmission subfile.
For example, 3 file D1, D2, D3 to be transmitted are obtained in step 201.Priority is according to sorting from high to low: D2, D1, D3.In step 202, file D1 to be transmitted is split as 2 subfile Z11, Z12, and file D2 to be transmitted is split as 2 subfile Z21, Z22, and file D3 to be transmitted is split as 4 subfile Z31, Z32, Z33, Z34.So, according to priority sequential delivery subfile from high to low, its order is: Z21, Z22, Z11, Z12, Z31, Z32, Z33, Z34.The transmitting procedure defining file to be transmitted is herein by the process of whole for subfile corresponding for this file to be transmitted end of transmission, for file D3 to be transmitted, only have and subfile Z31, Z32, Z33, Z34 are all sent, the transmitting procedure of file D3 to be transmitted is just finished.
For the transmitting procedure of a file to be transmitted, the subfile of its transmission correspondence can be transmitted according to the numeric order of subfile, also can opportunistic transmission.Such as, the transmitting procedure of file D3 to be transmitted can according to the order of Z31, Z32, Z33, Z34, also can according to the order of Z33, Z32, Z31, Z34.The present embodiment preferably transmits according to the numeric order of subfile, to be combined in order when receiving file.
Suppose the current subfile Z12 transmitting file D1 to be transmitted, subfile Z11 is end of transmission, if now there is the new file D4 to be transmitted obtained, its priority is higher than the priority of D1, namely, in remaining file D1, D3, D4 to be transmitted of not transferring, priority is according to sorting from high to low: D4, D1, D3.Now suspend the transmitting procedure of file D1 to be transmitted, record the subfile Z11 transmitted, preferentially send the file with higher priority according to the order of D4, D1, D3.Because subfile header comprises the content such as the number of subfile, the sequence number of subfile, therefore be easy to record the subfile transmitted, in practical operation, if transmit according to the numeric order of subfile, then only need record the subfile number transmitted.
Step 204, when all than described current file to be transmitted, there is the subfile end of transmission of higher priority after, the subfile do not transmitted in described current file to be transmitted is proceeded transmission.
Using above-mentioned given example as explanation, transmitting terminal sends file with the order of D4, D1, D3, after the transmitting procedure of the new file D4 to be transmitted obtained terminates, when sending file D1 to be transmitted, owing to recording the subfile Z11 transmitted, only send the subfile Z12 remaining and do not transfer.
The embodiment of the present invention introduces the mechanism of fractionation, file to be transmitted is divided into less data unit, even if whole file to be transmitted is very large, when the file transfer of real-time response higher priority, also can not therefore affect the subfile transferred, only need transmit in the complete rear recovery of the file transfer of higher priority.
embodiment two:
Consult Fig. 5, show the step schematic diagram of the document transmission method of the embodiment of the present invention two, method comprises the following steps.
Step 501, transmitting terminal obtains at least one file to be transmitted.
Step 502, judges whether the size of file to be transmitted is less than or equal to the maximum transfer size of subfile, if then perform step 503, otherwise performs step 504.
Step 503, using file to be transmitted as an independent subfile.
When determining that described file size to be transmitted is less than or equal to the maximum transfer size of described subfile, illustrate that file to be transmitted is without the need to splitting, using itself as a subfile.In the subfile header of this subfile, subfile number is 1, and the sequence number of subfile is 1.
Step 504, be at least two subfiles by described file declustering to be transmitted, each subfile carries the priority identical with corresponding file to be transmitted.
Step 505, deposits described subfile to internal storage data unit, and described internal storage data unit comprises the information area and data field, and the described information area is used for depositing described File header information and subfile header, and described data field is used for depositing sub-file data.
In order to manage each subfile more easily, find the subfile that priority is higher faster, the present embodiment sets a kind of internal memory form described below, all memory headrooms are divided into multiple identical internal fragmentation structure, each burst is called an internal storage data unit, and its number is determined by " memory headroom/(size+File header information+subfile header of subfile) ".In a particular application, the assignable memory headroom size of platform be taken into consideration, and the time of each internal storage data unit of poll from the beginning to the end, and then it is more reasonable to determine to there are how many internal storage data unit.Each internal storage data unit comprises the information area and data field, and the information area is used for depositing the whether occupied occupied mark of expression internal storage data unit, File header information, subfile header.Data field is used for depositing real sub-file data.Particularly, occupied identification value can be set to 0 or 1, if subfile has been filled into certain internal storage data unit by transmitting terminal, then putting it is 1, from then on priority judging unit (will be described in detail later) just can obtain precedence information in internal storage data unit, thus for judging priority height, if the data of this internal storage data unit remove by data transmission blocks, then putting it is 0, represents that internal memory filler cells (will be described in detail later) can be reloaded in this position new subfile.
Preferably, step 505 is further comprising the steps of:
Step 505a, when defining the new file to be transmitted obtained, judges whether to there is unappropriated internal storage data unit according to occupied mark, if exist, performs step 505b, otherwise performs step 505c.
Step 505b, if there is unappropriated internal storage data unit, then deposits subfile corresponding for the file to be transmitted newly obtained to this unappropriated internal storage data unit.
Step 505c, if there is not unappropriated internal storage data unit, and during the priority height of the file to be transmitted of the priority ratio current transmission of the file to be transmitted of described new acquisition, according to the number of subfile corresponding to the file to be transmitted of described new acquisition, releasing memory data cell; And subfile corresponding for the file to be transmitted of described new acquisition is deposited the internal storage data unit to having discharged.
It should be noted that, when internal memory is occupied full, when the priority of the subfile of the priority ratio current transmission of the new file to be transmitted obtained is high, then the file to be transmitted of this new acquisition needs preferentially to be sent, become the number of subfile to discharge the internal storage data unit of corresponding number (being appreciated that all internal storage data unit are likely all discharged) according to the new file declustering to be transmitted obtained, thus vacating space fill the subfile of high priority.
Be understandable that, if the priority of the subfile of the priority ratio current transmission of the new file to be transmitted obtained is low or equal, then continue a clock cycle of wait.
Step 506, all internal storage data unit of poll, according to the precedence information determination transmission sequence of the described information area.
Particularly, first the internal storage data unit that first available internal storage data unit will send as the next one can be taken out, then search a to the last internal storage data unit downwards, if there is the internal storage data unit of higher priority, just change it for the next internal storage data unit that will send.
Step 507, defines new subfile and deposits to internal storage data unit, and during the priority height of the subfile of the priority ratio current transmission of described new subfile, adjustment transmission sequence, is defined as the highest subfile of priority by described new subfile.
When detecting that in internal storage data unit the file File2 to be transmitted of higher priority exists, suppose that file File1 to be transmitted now have sent 10 subfiles, then can be suspended, start first subfile sending File2, if do not have the file of higher priority to enter during transmission File2, then after all receiving File2 file, proceed the transmission of the 11st subfile of File1.
Step 508, after determining the whole end of transmission of subfile that file to be transmitted is corresponding, according to the sequence number of described subfile, after abandoning described File header information and subfile header, order merges sub-file data.
Particularly, availablely judge the whether whole end of transmission of subfile by the number of subfile and the sequence number of subfile.After abandoning described File header information and subfile header, order merges sub-file data, and obtaining is exactly the data division of whole file to be transmitted.
Preferably, the sub-file data after receiving terminal is combined verifies, if variant with former file to be transmitted, then receiving terminal can notify that transmitting terminal resends.
embodiment three:
The file transfer means of the embodiment of the present invention comprises transmitting terminal and receiving terminal, consults Fig. 6, shows the sending end structure schematic diagram of the file transfer means of another embodiment of the present invention.Transmitting terminal comprises following content.
Acquiring unit 601, for obtaining at least one file to be transmitted.
