Specific embodiment
In order to make the objectives, technical solutions, and advantages of the present invention clearer, with reference to the accompanying drawings and embodiments, rightThe present invention is further elaborated.It should be appreciated that the specific embodiments described herein are merely illustrative of the present invention, andIt is not used in the restriction present invention.
Referring to Fig. 1, a kind of message synchronization system of the present invention, message when logging in multiple terminals applied to same user is sameStep mechanism, the synchronization system 100 include：
Newest first message sequence number is sent to terminal side after synchronization request for receiving by transmission unit 10.Specifically, when a certain user logs in multiple terminals by an application, due to terminal itself or communication, message difference can be generatedThe case where step.To solve this problem, a preset setting unit 40 in system 100, the generation plan for presetting message sequence numberSlightly, time setting incremented by successively specially is sent or received by message.
Comparing unit 20, for dividing locally-stored newest second message sequence number compared with first message sequence numberAnalysis.There is the latest sequence number of each message terminal side, since message SN has stringent incremental order, ifIf first message sequence number cannot be matched with second message sequence number, description messages are not carried out synchronization, and by comparing resultIt is sent to the processing of synchronous processing unit 30.
Synchronous processing unit 30 sends and synchronizes according to the comparing result of first message sequence number and second message sequence numberMessage content.Synchronous processing unit 30 can obtain corresponding according to the difference of first message sequence number and second message sequence numberThe message content of terminal side missing, and corresponding terminal side is sent it to, terminal side while update message sequence number.
Usually, if not synchronizing, second message sequence number can be less than first message sequence number, can according to this kind comparisonConveniently to obtain non-synchronizing information, and sends it to terminal and complete to synchronize.
The present invention also provides a kind of synchronizing devices including above system 100, can correspond to message server.
Referring to fig. 2, the present invention accordingly provides a kind of message synchronization method, can be real by system 100 as shown in Figure 1Existing, this method includes：
Newest first message sequence number is sent to terminal side after receiving synchronization request by step S201.Specifically, a certainWhen user logs in multiple terminals by an application, due to terminal itself or communication, the nonsynchronous feelings of message can be generatedCondition.To solve this problem, a preset setting unit 40 in system 100, for the generation strategy of presetting message sequence number, specificallyTo send or receive time setting incremented by successively by message.
Step S202, by locally-stored newest second message sequence number and the comparative analysis of first message sequence number.EventuallyThere is the latest sequence number of each message end side, since message SN has stringent incremental order, if first disappearsIf breath sequence number cannot be matched with second message sequence number, description messages are not carried out synchronization, and comparing result is sent toThe processing of synchronous processing unit 30.The comparison of the step can be realized by terminal side, can also be realized by service side.
Step S203, the comparing result of first message sequence number and second message sequence number send synchronization message content.TogetherCorresponding terminal side missing can be obtained according to the difference of first message sequence number and second message sequence number by walking processing unit 30Message content, and corresponding terminal side is sent it to, terminal side while update message sequence number.
Usually, if not synchronizing, second message sequence number can be less than first message sequence number, can according to this kind comparisonConveniently to obtain non-synchronizing information, and sends it to terminal and complete to synchronize.
In conclusion the present invention is by setting transmission unit, for receiving newest first message after synchronization requestSequence number is sent to terminal side；And by comparing unit by locally-stored newest second message sequence number and first message sequenceRow number comparative analysis；Synchronous processing unit is sent same according to the comparing result of first message sequence number and second message sequence numberWalk message content.If second message sequence number is less than first message sequence number, synchronous message synchronization will be needed to correspondingTerminal side.It whereby, can better synchronization message.
