Embodiment
In order to make the object of the invention, technical scheme and advantage clearer,, the present invention is further elaborated below in conjunction with accompanying drawing and embodiment.Should be appreciated that specific embodiment described herein only in order to explanation the present invention, and be not used in qualification the present invention.
Fig. 1 is a flow chart of cancelling synchronous method in the one embodiment of the invention, comprising:
101 when the needs cancellation is synchronous, generates the cancellation synchronization notice;
Can be between client (like mobile phone, PC etc.) and server, to carry out synchronously, also can be between two-server, to carry out.When needing cancellation synchronous, be meant after a synchronous side receives the synchronous request of cancellation, perhaps special circumstances taking place, be filled with or when making a mistake, when needing cancellation synchronous, carry out the synchronous operation of cancellation, and synchronization notice cancelled in generation as interior.
Can use the code that keeps among the synchronization makeup language SyncML in the cancellation synchronization notice of this generation; Or, use the Control Parameter that in host-host protocol, increases to represent that cancellation is synchronously.Control Parameter can be arranged among any one of host-host protocol message header, required parameter, message body.
A kind of situation is to generate and use the coded representation that keeps among the synchronization makeup language SyncML to cancel in the synchronous cancellation synchronization notice.In the existing special alarm code (Special Alert code) of SyncML, 226-250 is a reserved of codes.In the embodiment of the invention; The cancellation synchronization notice can adopt the arbitrary alarm coded representation cancellation among the 226-250 originally subsynchronous; This alarm code can be included in the message body of host-host protocol; With HTTP (HTTP Hypertext Transfer Protocol) is example, and message packet can be following:
<SyncML>
<SyncHdr>
<VerDTD>1.2</VerDTD>
<VerProto>SyncML/1.2</VerProto>

Wherein,<data>226</Data>In the cancellation of special alarm code 226 expression notice synchronization counterpart this is subsynchronous synchronously.Above-mentioned host-host protocol also can be other available bearing protocol, like OBEX (Object Exchange, Object Exchange) and WSP (WSP, Wireless Session Protocol) etc.
In addition, also can be in the Status of synch command, to use reserved of codes indication cancellation synchronously in the cancellation synchronization notice.Like this, the recipient just can learn that the other side hopes cancellation synchronously after receiving Status, thereby both sides finish simultaneous operation.Message packet is exemplified below:
<SyncML>

<data>519</Data><The 519 expression cancellations of-code are--> synchronously;
</Status>
</SyncBody>
</SyncML>In the last example, conditional code 519 is illustrated in the synchronizing process to be cancelled synchronously.After the recipient receives this cancellation synchronization notice, can be through extracting conditional code 519 and resolving its implication and carry out the synchronous operation of cancellation.
Another kind of mode is to generate and use the Control Parameter that in host-host protocol, increases to represent to cancel synchronous cancellation synchronization notice.Control Parameter can be arranged among any one of host-host protocol message header, required parameter, message body.
Host-host protocol can be HTTP, OBEX and WSP etc.With the HTTP bearing mode is example, as when needs cancellations is synchronous, when the HTTP message header increases Control Parameter, as increasing Control Parameter " X-DS-Abort-Sync ", and X-DS-Abort-Sync value is made as True, and the cancellation of expression notice synchronization counterpart is synchronous.Need not cancel when synchronous, not carry this parameter or the X-DS-Abort-Sync value is made as False at the HTTP message header.
Also can in the HTTP required parameter, increase Control Parameter, as:
POST
http://my.ds.com/sync?sid＝MS0yMTEuMTM4LjE4NC4yMDE&Abort-Sync＝y
Wherein, the Control Parameter of Abort-Sync=y for increasing, expression notifies the other side to cancel synchronously.
In addition, can also in HTTP message body, increase Control Parameter and notify the other side to cancel synchronously, this moment, message body can have various ways, and example is following:
Example message one:
<SyncML>
<AbortSync/>
</SyncML>
Example message two:
<SyncML>
<SyncHdr>
</SyncHdr>
<SyncBody>
<AbortSync/>
</SyncBody>
</SyncML>
Example message three:
<SyncML>
<SyncHdr>
<AbortSync/>
</SyncHdr>
<SyncBody>
</SyncBody>
</SyncML>
Example message four:
<AbortSync/>
Use Control Parameter < AbortSync/>expression to notify the other side to cancel synchronously in the above-mentioned example message.
Certainly, Control Parameter can be consulted to confirm that multiple manifestation mode can be arranged by synchronous each side.
102 send the cancellation synchronization notice gives said synchronous the other side, so that said synchronous the other side is said synchronously based on said cancellation synchronization notice cancellation.
A synchronous side sends to synchronous the other side with this synchronization notice after generating synchronization message, and this action can and be carried out before transmit leg is carried out the synchronous action of cancellation afterwards.
Through cancelling at needs when synchronous, send the cancellation synchronization notice and give synchronous the other side in the present embodiment, like this, the other side just can be after notified, and in time cancellation is originally subsynchronous.
In the embodiment shown in fig. 1, a synchronous side can also accept the cancellation sync response that the other side sends after sending the cancellation synchronization notice.This cancellation sync response representes that the other side has successfully cancelled synchronously, and the concrete form of cancellation synchronous response message and content are not given unnecessary details at this referring to embodiment shown in Figure 2.
In addition; In simultaneous session, synchronous double is synchronous a plurality of databases simultaneously, perhaps carry out some asynchronous operation; Such as exchange both sides' facility information, exchange both sides' authentication information etc.; In this case, cancellation possibly just finish simultaneous operation synchronously, and does not mean that finishing simultaneous session is connected with breaking off synchronously.At this moment, need both sides to indicate or arrange, after cancellation synchronously, whether can finish simultaneous session, break off bipartite connection.Therefore, after cancellation synchronously, can also further break off synchronous attended operation.
When the operation of breaking off synchronous connection, cancel synchronous transmit leg and can initiatively break off synchronous connection, also can break off synchronous connection according to the indication of synchronization counterpart.
When the synchronous transmit leg of cancellation initiatively breaks off synchronous connection, also need indicate the other side to connect synchronously in cancellation back disconnection synchronously.The indication that this disconnection connects is synchronously sent among can being included in the cancellation synchronization notice; Also can send separately, can be after receiving response message, to send when sending separately, also can be to receive that response message sends before.
After the transmission, transmit leg can break off synchronous connection at once, also can wait until to break off synchronously after the other side responds to connect again.Concrete operations can be to close synchronous port.
In the time of among the indication of breaking off connection synchronously is included in the cancellation synchronization notice, can be, also can increase an order again and indicate disconnection to connect synchronously with two kinds of meanings of a coded representation.
As using<data>226</Data>In special alarm code 226 promptly represent cancellation synchronously, also expression is broken off synchronously and being connected; Equally, also the serviceable condition sign indicating number 519, or<abortSync/>Order had both been represented cancellation synchronously, and also expression is broken off synchronously and being connected.
When above-mentioned code or order when only expression cancellation is synchronous, can in the cancellation synchronization notice, increase an order and indicate to break off synchronously and connect, perhaps send separately and break off the notice that connects synchronously and indicate.
As can be to indicate to break off synchronously with < Alert>order to connect, message packet is exemplified below:

<CmdID>1</CmdID>
<data>211</Data><-this code 211 shows it is to break off connecting--> synchronously;

Above code can be included among the synchronous notice of cancellation, also can be to send as a single message among being included in < SyncBody >.
Certainly, also can use Control Parameter, represent to break off synchronous connection like < CloseSession >.Can be included among the synchronous notice of cancellation, also can send separately.
The recipient who receives this order can select to reply or do not reply this message.When selecting to reply, promptly reply < Status >, return code is 200 (OK), agrees to break off synchronous connection.The recipient breaks off the operation that connects synchronously according to this command execution, specifically can be to close synchronous port.
Under the synchronous situation of cancellation, both sides' anchor value does not need to upgrade synchronously, keeps original anchor value.The synchronous anchor value mainly is the position that is used for writing down synchronizing process, is used for breakpoint transmission.Under the synchronous situation of cancellation, the very difficult position of learning sync break exactly of both sides.Therefore, in this case, in fact the synchronizing process of this cancellation is not complete, has no idea to realize breakpoint transmission, this is subsynchronous be regarded as invalid.When subsynchronous down, need hold consultation again, synchronous since the place of completion last time again.
Give the other side through sending the indication of breaking off synchronous connection in the present embodiment, and after transmission, break off connection synchronously, in time discharged the sync correlation resource.
Fig. 2 is the flow chart of the synchronous method of the cancellation in the another embodiment of the present invention, comprising:
201 receive the cancellation synchronization notice that synchronous the other side sends.
Can be between client (like mobile phone, PC etc.) and server, to carry out synchronously, also can be between two-server, to carry out.In carrying out synchronous process,, receive the cancellation synchronization notice of sending by the other side when the other side need cancel when synchronous.
202 resolve said cancellation synchronization notice, and discern the cancellation synchronically controlling information that said cancellation synchronization notice comprises.
Wherein, the cancellation synchronization notice can use the Control Parameter that increases in the code that keeps among the synchronization makeup language SyncML or the host-host protocol to represent cancellation synchronously, and object lesson is referring to embodiment as shown in Figure 1.The synchronous information of expression cancellation is the cancellation synchronically controlling information in the cancellation synchronization notice, that is to say, the cancellation synchronically controlling information can comprise: be used for representing to cancel the code that synchronous synchronization makeup language SyncML keeps in the cancellation synchronization notice; Or what increase in the host-host protocol of cancellation synchronization notice is used to represent to cancel synchronous Control Parameter.When resolving synchronization notice, need from the message that parses, discern these information.
203 according to said cancellation synchronically controlling information cancellation synchronously.
Cancelling synchronous concrete operations can be only to stop synchronous operation, and both sides can also keep connecting synchronously, carry out synchronous port and do not close, and just no longer carry out this simultaneous operation.
In the present embodiment, carry out cancellation simultaneous operation, realized the consistency of synchronous both sides when cancellation is synchronous, so that in time discharge the sync correlation resource through the cancellation synchronization notice of resolving the synchronization counterpart transmission.
In the synchronous method of cancellation shown in Figure 2; Can also be after carrying out cancellation simultaneous operation; Send the cancellation sync response for the transmit leg of cancellation synchronization notice, this cancellation sync response notice can be to send with form of message, can use the code that keeps among the synchronization makeup language SyncML; Or, use the Control Parameter that in host-host protocol, increases to represent successfully to cancel synchronously.Control Parameter can be arranged among any one of host-host protocol message header, required parameter, message body.
In the existing special alarm code (Special Alert code) of SyncML, 226-250 is a reserved of codes.In the embodiment of the invention, the cancellation sync response can adopt arbitrary alarm coded representation among the 226-250 cancel successfully that this is subsynchronous, distinguishes mutually but need notify the other side to cancel synchronous code with the expression used among the embodiment of Fig. 1.This alarm code can be included in the message body of host-host protocol, is example with the HTTP(Hypertext Transport Protocol), and message packet can be following:
Example message one:
<SyncML>
<SyncHdr>
<VerDTD>1.2</VerDTD>
<VerProto>SyncML/1.2</VerProto>

<Data>200</Data></Status>
</SyncBody>
</SyncML>
Example message two:
<StatusCode>200</StatusCode>
Wherein, in the example message one<data>200</Data>Successfully cancelled originally subsynchronous with code 200 expressions in the example message two.Above-mentioned host-host protocol also can be other available bearing protocol, like OBEX and WSP.
Another kind of mode is to use the Control Parameter that in host-host protocol, increases to represent successfully to cancel synchronously in the cancellation sync response.Control Parameter can be arranged among any one of host-host protocol message header, required parameter, message body.
Host-host protocol can be HTTP, OBEX and WSP etc.With the HTTP bearing mode is example,
As increasing Control Parameter " X-Abort-Sync-Result:200 " at the HTTP message header, expression successfully cancellation is synchronous.
Also can directly utilize HTTP condition of information representation cancellation result, like " HTTP/1.1 200 OK ", expression successfully cancellation is synchronous.
In addition, can also in HTTP message body, increase Control Parameter, represent successfully to cancel synchronously like < AbortSyncOK/>.
In the present embodiment; Transmit leg through to the cancellation synchronization notice returns the cancellation sync response; Expression has cancelled successfully that this is subsynchronous, has realized synchronous both sides mutual when cancellation is synchronous, makes the synchronous initiator of cancellation can in time understand the synchronous implementation status of cancellation.
In the synchronous method of cancellation shown in Figure 2, can also be after carrying out cancellation simultaneous operation, the transmit leg that write down this cancellation simultaneous operation and write down said cancellation synchronization notice.Specifically being record in daily record, can be this cancellation simultaneous operation to be recorded as the other side cancel synchronously.As: the cancellation synchronization notice that user end to server sends, server can write down this cancellation simultaneous operation in daily record after carrying out cancellation simultaneous operation according to this notice so, can be recorded as: " the client cancellation is synchronously "; After the cancellation synchronization notice that same client is sent according to server is carried out cancellation synchronously, can in daily record, write down this cancellation simultaneous operation and be: " the server cancellation is synchronous ".
In addition, after cancellation synchronously, can also further break off synchronous attended operation.When the operation of breaking off synchronous connection, the recipient of cancellation synchronization notice also can initiatively break off synchronous connection, or breaks off synchronous connection according to the indication of synchronization counterpart.
When the recipient of cancellation synchronization notice initiatively breaks off synchronous connection, also need indicate the other side to connect synchronously in cancellation back disconnection synchronously.Concrete, can in the cancellation sync response, can comprise and break off the indication that connects synchronously, perhaps, the recipient of cancellation synchronization notice sends the notice that an indication the other side breaks off synchronous connection separately.
The recipient of cancellation synchronization notice can use < Alert>order to represent to break off the indication of synchronous connection in cancelling sync response, also can < AbortSyncOK/>command definition successfully be cancelled synchronously, and synchronous the connection is broken off in indication.
Certainly, also can send a notice in addition, use < Alert>order or conditional code to represent to break off synchronous connection.The example that uses < Alert>to order can be referring to the explanation of embodiment as shown in Figure 1.
It is following that the user mode representation is broken off the example that connects synchronously in breaking off the notice that connects synchronously:
<SyncBody>
<！-->
<Status>
<！-->
<data>520</Data><-show to break off to connect--> synchronously;
</Status>
</SyncBody>
In the last example, the recipient uses < Status>to beam back an errored response, such as return code 520, shows that session is unusual, needs to break off synchronously to connect.The recipient can specifically can be to close synchronous port sending and should the execution of response back breaking off synchronous attended operation.
The recipient of cancellation synchronization notice gives the other side through sending the synchronous indication that connects of disconnection in the present embodiment, and after transmission, breaks off synchronous connection, has in time discharged Internet resources.
Fig. 3 is the structural representation of the synchronizer in the one embodiment of the invention, comprising:
