Embodiment
Basic thought of the present invention is when synchronous that user terminal is only downloaded and ownly locally produces the part of difference with the mail server data, rather than downloads fully, thereby realizes that variance data is synchronous, effectively reduced the data in synchronization amount; Simultaneously, by the raw data packets piecemeal is transmitted, make when interrupting appears in network, no longer again, transmit whole raw data packets, but the data block of bust this begins to continue transmission when network interrupts, thereby realized breakpoint transmission, reduced the synchronous communication amount, can not take a large amount of Internet resources.
Below in conjunction with the accompanying drawing in the embodiment of the invention, the technical scheme in the embodiment of the invention is clearly and completely described; Obviously, described embodiment only is the present invention's part embodiment, rather than whole embodiment.Based on the embodiment among the present invention, those of ordinary skills belong to the scope of protection of the invention not making the every other embodiment that is obtained under the creative work prerequisite.
The embodiment of the invention 1 provides the method that realizes data sync in a kind of mobile terminal PIM service, and as shown in Figure 2, this method comprises:
Step 201: the data message synchronization request that mobile terminal receive sends;
Concrete, mail server is after the connection of shaking hands synchronously that mobile terminal receive is initiated, return synchronous handshake response signal to described portable terminal, and lock the current data message record set of described portable terminal, originally subsynchronous with the synchronization request influence of avoiding other portable terminals to initiate;
Step 202:, determine the difference of the data message that local data message of preserving and described portable terminal are preserved, and return to described portable terminal by the data message record set that relatively all data message record sets are corresponding with described portable terminal;
Wherein, described difference part by comparing data information record set specified data information can be accomplished in several ways: for example, all data message record sets data message record set corresponding with described portable terminal of preserving in the mail server carried out XOR, and the result of described XOR is the difference part of data message; Certainly, also can adopt other existing modes to determine variance data information, repeat no more herein; And present embodiment has proposed a kind of mode by iteration generation variance data, and as shown in Figure 3: the initial data set on the supposition mail server is combined into A, x iThe variance data collection after the iteration, c have been carried out in expression the i time iThe expression portable terminal is in the data of uploading for the i time,
x 0=A
Then: x 1=x 0-c 1
............
x n=x n-1-c n-1
N represents that portable terminal uploads the number of times of data;
S301: whether before portable terminal sends synchronization request, determining this time is first iteration, and corresponding iteration sequence number is set is stored in the described synchronization request;
S302: after described mail server receives described synchronization request, determine whether to be first iteration, if, indicate described portable terminal to upload data packets then to described portable terminal return messages according to described iteration sequence number; Otherwise, directly determine variance data information and return to described portable terminal according to XOR result or other modes;
S303: after mail server receives the data packets that described portable terminal uploads, utilize XOR or other modes to determine discrepancy data equally, and discrepancy data is returned to described portable terminal.
In addition, the embodiment of the invention 3 proposes again after having determined variance data information, realizes breakpoint continuous transmission method, as shown in Figure 4, comprising:
Step 401: portable terminal sends query requests when sending synchronization request, in order to the block count of data query bag; Certainly, described query requests also can be included in the described synchronization request, repeats no more;
Step 402: mail server with described variance data packets of information piecemeal, and returns to described portable terminal with the block count of described packet after having determined variance data information;
Step 403: when grid generation communication failure, for example network interrupts, and described portable terminal at first judges whether to need to carry out breakpoint transmission, if desired, the sequence number of breakpoint re-transmitting data block is set then; Otherwise the sequence number of data block is set to 0, shows to transmit all data again;
Step 404: described portable terminal sends the data re-transmission request to described mail server, comprises the sequence number of re-transmitting data block in the described data re-transmission request;
Step 405: after described mail server receives described data re-transmission request, determine the data block that needs retransmit and return to described portable terminal according to the sequence number of the re-transmitting data block in this request;
Step 406: after the data block that described portable terminal returns mail server was saved in database, the sequence number of described re-transmitting data block was set to the next bit of former sequence number, and request retransmission once more, till all data all receive;
Certainly, in step 405, described mail server after receiving described repeat requests and determining the sequence number of re-transmitting data block, with this sequence number and afterwards the data block of each sequence number correspondence return to described portable terminal simultaneously, thereby finished data message synchronously; For example, suppose that the original differences packet is X, it is divided into the M piece, then: X = Σ i = 1 m x i ,
When the bust this of i blocks of data, when carrying out transfer of data once more not from x 0Blocks of data transmits again, but from x iBlocks of data begins to transmit again.
In addition, data message or data block mutual in the foregoing description all are to pack with the form of vcard agreement, and therefore vcard bag of every transmission all still needs professional handshake authentication; At this, the embodiment of the invention 4 proposes, on the basis of the foregoing description with a plurality of vcard packing data, form a vcard stream, and to carry out exchanges data between the server and client side be unit with vcard stream all, rather than be unit with vcard, promptly a plurality of vcard in vcard stream share a professional handshake authentication; So, can change the situation that each vcard needs professional handshake authentication, reduce non-business (for example professional handshake authentication etc.) data traffic;
It should be noted that the data that occur in the foregoing description all can adopt " binary system " to encode, coded system so more in the past, for example the base64 coding can reduce by about 30% code length; In addition, also can adopt the gzip data compression technique in the data exchange process, so also can significantly reduce the data traffic in the reciprocal process.
As can be seen, adopt the method for the embodiment of the invention, synchronous by variance data, effectively reduced the data in synchronization amount; Simultaneously, by the raw data packets piecemeal is transmitted, make when interrupting appears in network, no longer again, transmit whole raw data packets, but the data block of bust this begins to continue transmission when network interrupts, thereby realized breakpoint transmission, reduced the synchronous communication amount, saved a large amount of Internet resources; And, by different codings and compress mode also improved data payload ratio, reduced data traffic.
