Above-mentioned all alternatives, can adopt and combine arbitrarily formation embodiment of the present disclosure, this is no longer going to repeat them.
Fig. 2 is the flow chart of a kind of method of data synchronization according to an exemplary embodiment, and as shown in Figure 2, the method is used for, in server, comprising the following steps.
In step s 201, terminal to server sends data synchronization request, this data synchronization request carried terminal user ID.
When terminal triggering synchronous process, terminal can send data synchronization request to the server of correspondence.
In step S202, server receives data synchronization request.
Server is after receiving data synchronization request, can according to the concrete condition of data synchronization request, determine the method for synchronization, as carried the mark for marking terminal current data water level in this data synchronization request, when data water level be countless according to time, can think that this terminal does not now preserve any data, need to carry out the synchronous of valid data, and when data water level is greater than certain threshold value, can think that current need carry out common data syn-chronization, then based on data water level, data to be synchronized can be determined.
In step S203, server obtains valid data condition corresponding to this data synchronization request.
For different data types, server can safeguard different valid data conditions.As, for communication event, its valid data condition can be store at least one item in duration, contact person based on it.And synchronous for picture, file etc., its valid data condition can be store at least one item in the evaluating of duration, data based on it, and this concrete valid data condition describes in detail by subsequent embodiment.
In step S204, server is from high in the clouds data corresponding to this terminal user identification, and obtain valid data, these valid data are the high in the clouds data meeting valid data condition.
In the embodiment that the disclosure provides, from the high in the clouds data that this terminal user identification is corresponding, acquisition valid data can comprise at least one in following several mode:
First kind of way, store duration according to data, from the high in the clouds data that this terminal user identification is corresponding, obtain and store duration and meet the valid data of the first valid data condition.
For high in the clouds data, the storage duration of each data of server meeting respective record, with determine these data be when stored in, and store the long data of duration, likely user's unwanted data, therefore, in the process obtaining valid data, duration can be stored based on data and obtain.
Such as, in the embodiment that disclosure embodiment provides, store duration according to data, from the high in the clouds data that this terminal user identification is corresponding, obtain the data storing duration and do not exceed preset duration.That is to say, some times data too remote can be got rid of, this preset duration can be arranged in advance by user and be synchronized to server, also can be arranged by the historical operation of server according to user, as, the data before this user never accessed 1 year within a nearly time period, then can be set to preset duration by 1 year, certainly, the restriction of method that all do not provide by the present embodiment of the preset duration of this concrete set-up mode and setting.
And for example, in another embodiment that disclosure embodiment provides, storing duration from being short to long order according to data, from the high in the clouds data that this terminal user identification is corresponding, obtaining and storing the data that duration sequence is positioned at front first preset number.For some users, memory space is of great value, both the actual use of user can have been had influence on, also can have influence on the speed of service of terminal, therefore, can synchronous data volume be limited, in order to also the ageing of synchrodata can be ensured when ensureing saving memory space, can store duration according to data to sort, be valid data by the data acquisition of the first shorter for storage duration preset number.As, this first preset number can be hundreds of even several thousand, and preferably, this first preset number can be 1000.
Certainly, when storing duration based on data and obtaining valid data, can obtain in conjunction with the length and synchrodata amount storing duration, as, duration can be stored according to data, from the high in the clouds data that this terminal user identification is corresponding, obtain storage duration and do not exceed preset duration and be positioned at the data of front first preset number according to from sorting when being short to long sequence.Combinations thereof mode can have other modes of texturing, and disclosure embodiment does not repeat this.
Above-mentioned obtain manner for the such as communication event such as message registration or short message, picture, file synchronous all applicable, therefore not to repeat here.
The second way, contact person according to high in the clouds data corresponding to this terminal user identification, from the high in the clouds data that this terminal user identification is corresponding, obtain the valid data meeting the contact person of the second valid data condition.
For communication event, due to the difference of its contact person, this communication event may be different to the meaning of user, as, for the contact person that some often contact, user more may wish his data synchronous, that is to say, for user, the data of the contact person of often contact are valid data, and for data corresponding to some refuse messages, harassing calls etc., for user, do not belong to valid data, if carry out synchronously to this kind of data, not only occupied terminal memory space, but also the synchronous efficiency of valid data can be reduced.Therefore, in an embodiment of the present disclosure, this second way specifically can comprise: according to the cohesion between contact person and terminal use, from the high in the clouds data that this terminal user identification is corresponding, obtain the data of the first contact person, between this first contact person and this terminal use, cohesion is greater than predetermined threshold value.
In this embodiment, server can by the communication frequency between the contact person in the data of high in the clouds and terminal use, as the frequency of sending short messages or the frequency etc. of making a phone call, determine the cohesion between contact person and terminal use, when cohesion is greater than predetermined threshold value, can think that the data of this contact person are valid data for terminal use, therefore, carry out synchronously based on cohesion, can greatly reduce to need synchronous data volume.
In another embodiment of the present disclosure, this second way specifically can comprise: according to the contact person of default harassing call database with these high in the clouds data, from the high in the clouds data that this terminal user identification is corresponding, obtain the data of the second contact person, the artificial contact person not included in this default harassing call database of this second contact.
In this embodiment, server can safeguard a default harassing call database, for storing harassing call number, as promoted class, commercial paper, swindle class etc., the data of this kind of contact person do not belong to valid data for terminal use, therefore, can according to the contact person of high in the clouds data, harassing call database is preset in inquiry, by being included in the contact data filtering in default harassing call database, obtains the data of the second contact person.In addition, for the communication event of some business, as the short message etc. of the merchant service propelling movement that some users register, for terminal use, also lack validity, therefore, server can also safeguard Yellow Page call database, by the business communication event filtering of some businessmans etc., thus to obtain the data of the 3rd contact person, the artificial contact person not included in this Yellow Page call database of the 3rd contact.
In actual scene, the above-mentioned acquisition based on cohesion, default harassing call database and Yellow Page call database also can in conjunction with carrying out, as, adopt cohesion, preset at least one item in harassing call database and Yellow Page call database, some unnecessary high in the clouds data of filtering, thus get valid data.
In this scenario, these high in the clouds data comprise short message record or message registration.When obtaining valid data, for each contact person determined, also can limit the downloading data of each contact person, as, for each first contact person, be only valid data by the high in the clouds data acquisition of the some of each first contact person, as, for the first contact person, only its nearest 10 message registrations are retrieved as valid data, to carry out data syn-chronization.This restriction can be applied to the valid data acquisition process for first, second and the 3rd contact person, and disclosure embodiment is not construed as limiting this.
Certainly, if terminal use also thinks other synchronous relevant to some contact persons high in the clouds data, can also be obtained from server by data synchronization request.
The third mode, according to data evaluation parameter, from the high in the clouds data that this terminal user identification is corresponding, obtain the valid data that data evaluatings meets the 3rd valid data condition.
For the data such as picture, file, because its data type is different, can have different data evaluation parameters, e.g., for picture, its data evaluation parameter can be the definition of picture, and for file, can be the size etc. of this article part.User is when pictures taken; in order to ensure to photograph best picture, usually multiple similar pictures can be retained, therefore; these multiple similar diagram sector-meetings are uploaded to server; and when subsequent synchronisation, first server can scan high in the clouds data, multiple similar pictures are divided into one group; thus in this similar pictures group; obtain a top-quality picture, this top-quality picture is carried out data syn-chronization as valid data, to reduce taking of memory space.Correspondingly, for data evaluation parameter for definition is described, this process can comprise: when the high in the clouds data that this terminal user identification is corresponding comprise multiple similar pictures, compare the definition of these multiple similar pictures; The maximum picture of definition is obtained from these multiple similar pictures.
In step S205, these valid data are sent to terminal by server, and this terminal is carried out synchronously based on these valid data.
In step S206, terminal receives valid data, and carries out synchronously based on these valid data.
Above-mentioned steps S205-S206 is data transmission procedure and data storage procedure, and disclosure embodiment does not repeat this.
In the process of carrying out data syn-chronization, only more synchronous for the valid data having actual use meaning user, and unnecessary data are not carried out synchronously, make when data volume is larger, can synchronous efficiency be improved, avoid the waste to memory space and customer flow.Further, from the data of high in the clouds, valid data are obtained by adopting different valid data conditions, synchronously, can not can also avoid the interference of some hashes, improve data synchronization efficiency greatly some times too remote carrying out when can make synchronous.
