The control structure principle of the distributed multi-source data that can be synchronous of the present invention as shown in Figure 2, comprise that application cache data, data insert engine and several distributed data sources, these distributed data sources comprise local distributed data, other mobile phone distributed datas and network distribution type data or the like.Several distributed data sources insert engine with data respectively and are connected, and data insert engine and also are connected with the application cache data.Data insert engine can carry out data access control, synchronous triggering, and recombinates based on the multi-source data of priority optimization, probability optimization or the like rule.Data sync can be carried out respectively between application cache data and each distributed data source, also can between several distributed data sources, carry out mutually: as shown in the figure, between local distributed data and other mobile phone distributed datas, between local distributed data and the network distribution type data, between other mobile phone distributed datas and the network distribution type data or the like.In a word, Fig. 2 has showed the data recombination of multi-source.
According to shown in Figure 2, we set a concrete application scenarios:
Use in the mobile phone, its data are (cache) in the buffer memory of mobile phone, and the data in the buffer memory are from three different sources: one, the storage file of mobile phone this locality; Its two, other one by the storage file in the mobile phone of bluetooth wireless link; Its three, by the GPRS wireless access, at a data file of network server end; These three data sources are in different positions.
Among Fig. 2, it is core that data insert engine, and it has following major function:
1. determined the access control of data.Access device can specifically define in such a way:
A) equipment of the specific set of regulation can swap data, can exchange appointment data (address list) such as the mobile phone of only permitting NOKIA series S60 platform, or, have only the mobile phone of Qualcomm binary runtime environment for wireless can exchange the data (missed call information) of agreement;

Need the data of reorganization logically can be divided into little data block, be referred to as information unit (IE informationelement), the data of each IE all might be from different data sources, and the reorganization rule has determined that the IE of these data sources handles.
As shown in Figure 4, recombination data is from different sources, and data insert the combination that engine has determined information element.Comprise the application cache data, distributed data source 1 (this locality), distributed data source 2 (mobile phone), or the like, until distributed data source n (network).
Comprise 3 information unit IE in the distributed data source 1 (this locality), be numbered 1-IE1,1-IE3,1-IEn.
Comprise 4 information unit IE in the distributed data source 2 (mobile phone), be numbered 2-IE1,2-IE2,2-IE4,2-IEn.
Comprise 3 information unit IE among the distributed data source n (network), be numbered n-IE2, n-IE3, n-IEn.
Because reason is identical, does not discuss for clipped.The 1st to n of information unit in the application cache data, as can be seen from Figure 4, wherein each all is to choose from corresponding distributed data source: the 1st is 1-IE1, the 2nd is 2-IE2, and the 3rd is n-IE3, and the 4th is 2-IE4, or the like, n is 1-IEn.Finish the data recombination of multi-source thus.
The data recombination rule can be including, but not limited to following several:
A) priority level is set, and such as setting local high priority data, secondly is data in mobile phone, and the 3rd is network data;
B) set according to empirical probability,, adopt the data source of maximum probability,, adopt time data source of big probability etc. if do not have such as remember the mode of obtaining data in the past;
C), get the weighting or the calculating such as algebraically, geometry or logic of two or more data sources, to obtain IE in the reconstruct data to the further processing of data;
D) other reconstructing methods.
As shown in Figure 5, being combined into the application cache data may further comprise the steps: carry out the data recombination rule in advance and set; Determine several information units of needs reorganization according to the data recombination rule; Obtain the data in a series of data sources, and parse the information unit that has in each data source respectively; From the information unit that parses, select several information units to be combined into the application cache data according to the data recombination rule.
3. the trigger mechanism of information synchronization
Because there is inconsistent place probably in the application cache data of each information source and reconstruct, data synchronization becomes a kind of possible demand, and data synchronization comprises following several:
A) data sync between the distributed data source;
B) between Cache data and local data or other distributed data sources synchronously;
What deserves to be explained is: perhaps do not have direct communication linkage between the distributed data source, but these data sources all and have communication link between main frame, so the communication synchronization between them can finish by main frame, and needn't directly set up communication linkage.
The methods of information synchronization are various, comprise two-way, unidirectional, have ready conditions or protectiveness synchronous etc., these can be determined by synchronous triggering mechanism.Such as, we can set the unidirectional of Cache data and local data makes local data obtain renewal fully fully synchronously, consistent with cache.
In a word, the multi-source data control method has wide application scenarios flexibly, in wireless interconnected today, and the network storage and various access technology, various application mode makes the present invention have unique commercial value.
