Description

Data synchronization system and method thereof

The present invention relates to a data synchronization system and method thereof, and more particularly to a data synchronization system and method thereof applied to a multi-user terminal.

In recent years, with the popularity of the Internet and the vigorous development of various mobile devices, the demand for data synchronization has also increased significantly.

In general, the conventional data synchronization method is that two devices (hereinafter referred to as user terminals) mutually synchronize data with each other, such as files or parameters. However, since only two clients can synchronize at a time, when the number of clients increases, it is necessary to operate multiple times to enable all clients to complete synchronization processing, which has the problem of synchronization inconvenience.

In view of this, some manufacturers have proposed to use cloud technology to set up a synchronous server to coordinate the synchronization processing of all users. For example, when the client connects to the synchronous server, it automatically performs synchronization. In this way, the synchronization processing efficiency of the client can be improved. However, in this way, it must be ensured that all the clients can connect with the synchronization server, otherwise it is still impossible to complete the synchronization processing of all the users, but in fact, it is difficult to ensure that all the clients can connect with the synchronization server. The above method still cannot effectively solve the problem of multi-user synchronization inconvenience.

In summary, it can be seen that there has been a problem of multi-user synchronization inconvenience in the prior art for a long time, so it is necessary to propose an improved technical means to solve this problem.

In view of the problems of the prior art, the present invention discloses a data synchronization system. System and its methods.

The data synchronization system disclosed in the present invention comprises: a synchronization server and a client. The synchronous server stores the first synchronization data, and the UE stores the second synchronization data. The user terminal includes: a detection module, a transmission module, a selection module, and a synchronization module. The detection module is configured to detect the connection state with the synchronization server. When the connection state between the client and the synchronization server is connected, the user terminal is used as the connection user terminal; the transmission module is used for the user. When the terminal is the connected client, the preset weight information is broadcasted, and the weight information broadcasted by other connected users is received as the comparison message; the selection module is used to compare the connection terminal with the highest weight in the weight order table. The synchronization module is configured to: when the user end is not the synchronization processing end, synchronize the processing between the user end and the synchronization processing end according to the second synchronization data, and confirm the synchronization processing end on the user end and confirm After the synchronization process is completed with other clients, the synchronization server is connected to the synchronization server to synchronize the synchronization processing end with the synchronization server according to the first synchronization data. After the synchronization processing end and the synchronization server complete the synchronization processing, the synchronization processing end Then synchronize with all users.

The data synchronization method of the present invention is applied to a network environment having a synchronous server and a client, and the steps include: synchronizing the server to store the first synchronization data, and each client separately storing the second synchronization data; Detecting the connection state of the synchronization server, when the connection state of the client and the synchronization server is connected, the user terminal will serve as the connection user terminal; when the user terminal is the connection user terminal, the preset is broadcasted. Weighting the message, and receiving the weight information broadcast by the other connected client as the comparison message; the client compares the weight message and the comparison message to generate a weight order table, and selects the highest weight connected user from the weight order table The end is used as a synchronization processing end; when the user end is not the synchronization processing end, the The user end synchronizes with the synchronization processing end, and after the user side is the synchronization processing end and confirms that the synchronization process has been completed with other users, the connection to the synchronization server is performed to synchronize the processing end and the synchronization server according to the first synchronization data. Synchronization processing is performed, and after the synchronization processing end and the synchronization server end complete the synchronization processing, the synchronization processing end performs synchronization processing with all the user terminals.

The system and method disclosed in the present invention are as above, and the difference from the prior art is that the present invention selects one of the user terminals as a synchronization processing terminal and the synchronization processing terminal through a user terminal that can be connected to the synchronization server. After all the clients are synchronized, the synchronization processor synchronizes the synchronization server.

Through the above technical means, the present invention can achieve the technical effect of improving the synchronization convenience of the multi-user terminal.

The embodiments of the present invention will be described in detail below with reference to the drawings and embodiments, so that the application of the technical means to solve the technical problems and achieve the technical effects can be fully understood and implemented.

Before describing the data synchronization system and method thereof disclosed in the present invention, the terminology defined by the present invention is first described. The synchronous server terminal of the present invention refers to a server host connected to the Internet to provide storage. The space is used for synchronization processing; the user terminal refers to a computer operated by a user, such as a computer host, a personal digital assistant, a smart phone, and the like. In particular, the client that can connect to the synchronous server through the Internet will be regarded as the connection client, and the computer with the highest performance will be selected as the synchronization processor from the connection client as the other. The mediation host that synchronizes the client and the synchronous server will describe the architecture of the synchronous server and the client in detail later.

The data synchronization system and the method thereof are further described below with reference to the drawings. Please refer to FIG. 1 and FIG. 1 is a system block diagram of a data synchronization system according to the present invention. The system includes: a synchronous server 110 and a user. End 120. The synchronization server 110 stores the first synchronization data, and the first synchronization data includes at least the modification time, the modified quantity, the modification data, and the like, and the determination data for performing the synchronization processing. For example, if a plurality of files stored in the synchronization server 110 are modified, the synchronization server 110 records the last modification time, the modified file number, the modified file name, and the like, so as to generate the first synchronization data and The first sync data is used as a basis for the synchronization process. In actual implementation, the synchronization server 110 and the Internet 130 are connected to each other, and at least one of the clients 120 needs to be connected to the Internet 130, and different clients 120 need to be connected to each other, such as: a transmission area. Network, transmission line, etc.

For each part of the client 120, each client 120 stores second synchronization data, and each client 120 includes a detection module 121, a transmission module 122, a selection module 123, and a synchronization module 124. The detection module 121 is configured to detect the connection state with the synchronization server 110. When the connection state between the client 120 and the synchronization server 110 is connected, it is used as a connection client. It should be noted that the second synchronization data and the first synchronization data include at least modification data, such as modification time, modification quantity, and modification data, for performing synchronization processing.

The transmission module 122 is configured to broadcast a preset weight information when the client 120 is a connected client, for example, “A; 5” represents a weight message (where “A” represents a client identifier; “5” "Represents the weight value" and receives the weight information broadcast by other connected clients as the comparison message. For example, assume that multiple client terminals 120 can be connected to the synchronization server 110 via the Internet 130. The transmission module 122 will transmit its own weight information to other clients 120 through broadcast, and receive weight information broadcast by other clients 120, such as: the value "B; 4" is used as the comparison message. . In this way, the client 120 has the weight information (ie, the comparison message) of the other client 120 in addition to the weight information preset by itself.

The selection module 123 is configured to compare the weight information and the comparison message to generate a weight order table, and select the highest weight connection user terminal from the weight order table as the synchronization processing end. In the above example, the weight information of the client 120 itself is the value "A; 5", and the weight information of the other client 120 is compared with the value of the message "B; 4", so the size can be based on the comparison. The client identifiers are arranged in order from the largest to the smallest to generate a weight order table, such as: "A, B" (since the weight value "5" is greater than the weight value "4", the client identifier "A" is arranged in the client identifier" The front of B", which is ranked first in the front also represents the highest weight), and then, the connected client whose client side is identified as "A" is selected as the synchronization processing end. In practical implementation, the weight value can be replaced by a connection parameter, such as network rate or bandwidth, or by processor parameters such as processor clock. For example, the connection parameter can be recorded as " 20 Mbps", the processor parameters can be recorded as "1.7 GHz", and the order is also sorted according to the size of the values. It should be noted that although the present invention is described by way of example above, it is not limited thereto, and any manner in which a connection client can be selected as a synchronization processing terminal according to a weight message does not deviate from the application scope of the present invention.

The synchronization module 124 is configured to synchronize the processing of the client 120 with the synchronization processing end according to the second synchronization data when the user terminal 120 is not the synchronization processing end, and the synchronization processing end of the user terminal 120 and confirm that it has been combined with other After the client 120 completes the synchronization process, it connects to the synchronization server 110 to make the synchronization according to the first synchronization data. The synchronization end synchronizes with the synchronization server 110. After the synchronization processing end and the synchronization server 110 complete the synchronization process, the synchronization processing end performs synchronization processing with all other client terminals 120. In other words, the client 120 that is not the synchronization processor first synchronizes with the synchronization processor, and then the synchronization processor synchronizes with the synchronization server 110. Then, after the synchronization processor and the synchronization server 110 complete the synchronization process, the synchronization is performed. The processing end will perform synchronization processing with all other client terminals 120 again. Since the synchronization processing according to the synchronization data is a conventional technique, it will not be described here.

In addition, the client 120 may further include a decentralized module 125 for connecting to the synchronization server 110 through the Internet 130 when the client 120 is a connected client, and according to the first synchronization data and the second synchronization data. Select at least one data to be modified (eg, file or parameter) from the modified data for synchronization. In other words, this synchronization method is collaborative synchronization (all the files that need to be synchronized are divided into multiple partial files, and each connected client only synchronizes one partial file, and after all the partial files are synchronized, It is integrated into a complete archive, and then all users are synchronized with the entire file). In practical implementation, the client 120 may also include a distribution module 126 for calculating the number of files to be synchronized before the client 120 is synchronized and synchronized with the synchronization server 110, and matching the number of files to be connected to the client. The quantity and the weight information thereof are used to allocate the files that need to be synchronized between the synchronization processing end and the connection user terminals, so that the synchronization processing end and the connected connection terminals can respectively perform the data to be synchronized through the Internet 130 and the synchronization server 110. Synchronize. Then, after the synchronization processing end and each connection user end complete downloading the data that needs to be synchronized, the distribution module 126 synchronizes the data synchronized by the synchronization processing end and each connection user end from the synchronization server end 110 again. Integrated processing.

Please refer to "Figure 2A" and "Figure 2B", "Figure 2A" and "No. 2B is a flowchart of a method for the data synchronization method of the present invention. The steps include: in a network environment having a synchronization server 110 and a client 120, the synchronization server 110 stores the first synchronization data, and each client 120 separately The second synchronization data is stored (step 210); the client 120 detects the connection state with the synchronization server 110, and when the connection state of the client 120 and the synchronization server 110 is connected, it is used as a connection. a client (step 220); when the client 120 is a connected client, broadcasting a preset weight message, and receiving a weight message broadcast by another connected client as a comparison message (step 230); the user The terminal 120 compares the weight information and the comparison message to generate a weight order table, and selects the highest weighted connection client from the weight order table as the synchronization processing end (step 240); the user terminal 120 is not the synchronization processing end. And the user terminal 120 performs synchronization processing with the synchronization processing end according to the second synchronization data, and after the user terminal 120 is the synchronization processing end and confirms that synchronization processing has been completed with the other user terminals 120, The line-to-synchronization server 110 synchronizes the synchronization processing end with the synchronization server 110 according to the first synchronization data. After the synchronization processing end and the synchronization server 110 complete the synchronization processing, the synchronization processing end performs the same with all the user terminals 120. Synchronization processing (step 250). Through the above steps, one of the user terminals that can be connected to the synchronous server can be selected as the synchronization processing end, and all the user terminals are synchronized by the synchronization processing end, and then the synchronous processing terminal synchronizes the servo. The end is synchronized.

In actual implementation, in step 250, when the client 120 is a connected client, it may be connected to the synchronization server 110 and select at least one of the first synchronization data and the second synchronization data from the modification data. Synchronization (step 260); or before the user terminal 120 is the synchronization processing end and the synchronization processing with the synchronization server 110, the number of data to be synchronized is calculated in advance and the synchronization processing end is set according to the number of connected users. After the data is synchronized, the synchronization processing terminal and each of the connection user terminals are synchronized with the synchronization server 110 through the Internet 130, and the synchronization processing terminal and the connection client are synchronized again. Processing (step 270). In actual implementation, step 260 synchronizes the synchronization processing terminal and each of the connection user terminals with the synchronization server 110 through the Internet 130 (eg, only partially synchronizes data), and step 270 Synchronizing the synchronization processor with each wired client is completely synchronized (eg, synchronizing all data). Since some synchronous and fully synchronized synchronization processing methods are well-known techniques, no further details are provided herein.

The following description will be made by way of example with reference to "Fig. 3" and "Fig. 4". Please refer to "Fig. 3" and "Fig. 3" for the first embodiment of data synchronization processing to which the present invention is applied. schematic diagram. First, the UEs (120a, 120b, and 120c) detect the connection state with the synchronization server 110. In this example, the UEs (120a and 120b) can be connected to the synchronization server 110 via the Internet 130. The client 120c cannot be connected to the synchronization server 110, but can be connected to other clients (120a and 120b) through the area network 131. Therefore, the detection module 121 of the client (120a and 120b) regards itself as a connection client. Then, since the UEs (120a and 120b) are connected clients, the transmission module 122 broadcasts a preset weight message and receives the weight information broadcast by other connected clients as a comparison message, in other words, The client 120a broadcasts its own preset weight information to the client 120b for the client 120b to use as the comparison message, and vice versa. Then, the selection module 123 of the client (120a and 120b) compares the weight information and the comparison message to generate a weight order table, and assumes that the weight information preset by the client 120a is “A; 10 Mbps” and preset by the client 120b. The weight message is “B; 8Mbps”, where “A” and “B” represent the client identifier; “10Mbps” and “8Mbps” represent the network parameters (frequency) Width), the weight sequence table generated by the selection module 123 can be arranged in order according to the bandwidth recorded by the network parameters, such as the record as "A, B" (the top one represents the largest weight), and from The client 120a corresponding to the client identifier "A" is selected as the synchronization processing terminal in the weight order table.

Next, since the UEs (120b and 120c) are not synchronized, the UEs (120b and 120c) are synchronized with the synchronization processor (ie, the client 120a) according to the second synchronization data stored therein, and After confirming that the synchronization process has been completed with the other clients (120b and 120c), the client 120a connects to the synchronization server 110 via the Internet 130 to synchronize the processing terminal (ie, the client 120a) with the synchronization servo according to the first synchronization data. The terminal 110 performs synchronization processing.

In addition, after the synchronization processing end (ie, the client 120a) confirms that the synchronization process has been completed with the other clients (120b and 120c), the synchronization processing end (ie, the client 120a) can calculate the synchronization between the synchronization server and the synchronization server 110. The amount of data (for example, 180 MB of data needs to be downloaded from the synchronization server 110), and according to the connection client (ie, the client 120a and the client 120b; in this example, the client 120a is the synchronization processor and the connection client at the same time. And their respective weight messages (assuming that the connection parameters are weighted messages, the weight information of the client 120a and the client 120b may be "10 Mbps" and "8 Mbps" respectively) for the connection client (ie, the client 120a) A 100 MB data download task is assigned, and an 80 MB data download task is assigned to the connected client (ie, the client 120b). After the respective download tasks of the client 120a and the client 120b are completed, the client 120a and the client 120b perform data synchronization, and transmit the 80 MB data downloaded by the client 120b to the client 120a, so that the client 120a has the required The complete 180MB of information. Then, the other UEs can be synchronized with the client 120a to obtain the complete 180M data. This is the completion The client terminals (120a, 120b, and 120c) are synchronized with the data of the sync server 110.

Please refer to FIG. 4, and FIG. 4 is a schematic diagram of a second embodiment for performing data synchronization processing by applying the present invention. In actual implementation, the client 120 may indicate that only one (ie, the client 120a) can be connected to the synchronization server 110 through the Internet 130 as shown in FIG. 4, and therefore, the UEs (120a and 120c) are detected. After detecting the connection state with the synchronization server 110, the user module 120a functions as a connection client. At this time, since the client 120a is the connection client, the transmission module 122 broadcasts the weight message, but since the client 120c is not the connection client, the client 120a does not receive the weight message broadcast by the client 120c. As the comparison message, at this time, the transmission module 122 may use a null value (Null) as the comparison message after the preset waiting time is exceeded, and the selection module 123 detects the null value during the comparison process. The weight sequence table generated by the time will only record the user end identifier of the client 120a itself, and the connection parameters or processor parameters of the client 120a itself. The subsequent synchronization processing flow is the same as that of the first embodiment described above, so it is not here. Repeat more.

In summary, it can be seen that the difference between the present invention and the prior art is that one of the UEs that can be connected to the synchronization server is selected as the synchronization processing terminal, and all the user terminals are performed by the synchronization processing terminal. After the synchronization, the synchronization processor synchronizes the synchronization server, and the technical problem can be solved by the prior art, thereby achieving the technical effect of improving the synchronization convenience of the multi-user.

While the present invention has been described above in the foregoing embodiments, it is not intended to limit the invention, and the invention may be modified and modified without departing from the spirit and scope of the invention.
