Abstract

A method for sharing and synchronizing data in a Local Area Network is provided for use by a network connection device which is installed with a first synchronization procedure and stores plural entries of data. According to the method, the network connection device determines whether itself has a server tag when starting the first synchronization procedure. If yes, and upon receiving a connection request from a second device, the network connection device connects with the second device, reads a data selection message therefrom, and determines according to the message whether the update date of the corresponding data in the network connection device is later than that of the corresponding data in the second device. If yes, the network connection device sends its own data to the second device; otherwise, the network connection device receives data from the second device. Thus, a user can create a private cloud in a Local Area Network, allowing data to be rapidly shared and synchronized between devices.

Description

Method for data sharing and data synchronization in a local area network

The invention relates to a method for data sharing and data synchronization, in particular to a method for data sharing and data synchronization in a local area network, and the user can set any terminal device as a server according to the requirements of use.

According to the existing computer science, we often use the "cloud" pattern as a schematic representation of a large number of servers and underlying infrastructure on the Internet, while "end" refers to the ability to use various communication interfaces (such as : Browsers) Connect to the Internet's terminal devices (eg, smart phones, computers), so users do not need to have an understanding of the "cloud" infrastructure, and do not need to have a high degree of expertise, as long as they own The terminal device can quickly obtain the services and resources it needs from the "cloud". Therefore, cloud service has become one of the most widely used computer technologies.

Generally speaking, most of the existing cloud services are provided by network service providers. Among them, cloud backup services are favored by people. For example, users can use personal computers to transfer files to network service providers. The cyberspace is stored. 嗣, when the user goes out or works, if the file is used, the user can download the file by using a smart phone or a notebook computer, meaning that the user does not need to load the file. By storing it in multiple devices, you can quickly get the files you need. However, in the foregoing usage mode, the user's file is stored in the server of the network service provider, and for the user who attaches great importance to his privacy right, if the important information is placed on the server of the network service provider, In the meantime, there will inevitably be concerns about data leakage, causing users' concerns about use. Therefore, there are still many users who are afraid to use the cloud backup service provided by the network service provider in the face of some confidential information, so that the user must repeat the same data between different devices. Copy, causing Inconvenience in use.

In summary, as the data is stored in the "public cloud" provided by the network service provider, the user's psychological concerns may be caused, and the user cannot enjoy the benefits of the cloud backup service. Therefore, how to address the above problem Designing a better cloud service is an important issue for related network operators.

In view of the user's privacy during the cloud service, there are still many concerns about the privacy of the "public cloud". Therefore, after long-term efforts and experiments, the inventor finally developed and designed a data of the present invention in the local area network. Sharing the method of synchronizing data, with the aim of providing the user with a "private cloud" cloud service by the present invention, and enabling the industry to have a place in the existing network market.

An object of the present invention is to provide a method for data sharing and data synchronization in a local area network, which is mainly for a user to construct a "private cloud" in a local area network, and can quickly synchronize more The data between the terminal devices is repeated, and the same data is repeatedly copied into a plurality of terminal devices, which is applied to a terminal device (eg, a smart phone or a tablet computer). The terminal device includes a central processing unit, a network unit and a storage unit, wherein the central processing unit electrically connects the network unit and the storage unit respectively to transmit messages to the network unit and the storage unit, or receive The message from the network unit and the storage unit, the network unit can receive the network information transmitted from the external area network, or transmit the network message to the external area network, and the first synchronization is installed in the storage unit. a program, and storing a plurality of data data, when the terminal device starts the first synchronization program (ie, starts the synchronization function), it first determines whether it has a server tag, if yes, the server itself is set as a server, and after receiving the link request message of other devices transmitted from the network unit, a connection is established with the other device, and the other device is read and read. The selected data message is selected, and based on the content of the selected data message, the updated date of the corresponding data is obtained to compare the data stored in the data with the update date of the data corresponding to the other device, and When the update date of the corresponding data data is later, the corresponding data data is transmitted to the other device; otherwise, the data data transmitted by the other device is received and stored in the storage unit. In this way, the user can set the required terminal device according to the usage requirements. For the server, and in the local area network at home, the terminal device carried by itself is synchronized with the data in other devices, so as to avoid the user having to repeatedly store the same data data on different devices. Effectively improve the user's convenience in use.

Another object of the present invention is to install a second synchronization program in the storage unit of the terminal device, so that the terminal device can be connected to the home network by the external network, and the data data is synchronously updated. When the terminal device starts the second synchronization process (ie, starts another synchronization function), it establishes a connection with the server through a web browser when the location of the server to be connected is set. , which selects the data to be synchronized, and transmits a selection data message to the server, waiting for the server to determine which data data is updated later, and thus can receive the data data sent by the server. Or according to one of the servers, the data message is required to transmit its own data to the server. In this way, although the user carries the terminal device out of the door, the data can be synchronized with the server in the home network of the home to reduce the user's subsequent repeated storage of data.

For your convenience, the review committee can make a further understanding and understanding of the purpose, technical features and effects of the present invention. The embodiments are combined with the drawings, and the details are as follows:

The present invention is a method for data sharing and data synchronization in a local area network. Referring to FIG. 1 , in an embodiment, the method is applied to at least one terminal device having a networking function and a synchronization function. 1 , the terminal device 1 can be a smart phone, a tablet pc, a personal digital assistant (PDA), etc., wherein the terminal device 1 includes a central processing unit 11 and a network unit 13 And a storage unit 15, the central processing unit 11 is electrically connected to the network unit 13 and the storage unit 15, respectively, and can transmit messages to the network unit 13 and the storage unit 15 to control the network unit 13 and the storage unit. 15 executes the corresponding program behavior, and the central processing unit 11 can also receive messages from the network unit 13 and the storage unit 15 and execute corresponding program behaviors.

As shown in FIG. 1 , the network unit 13 can receive network information transmitted from an external network or transmit network information to an external network. In addition, the storage unit 15 has a built-in a first synchronization program 151 and a second synchronization program 152, and storing a plurality of data data 154 therein, when the terminal device 1 determines that it is in a regional network (ie, an area constructed using a private IP address) In the network, the synchronization function is started (ie, the first synchronization program 151 is executed), and the central processing unit 11 determines whether the terminal device 1 itself has one of the server tags in the local area network. In the case of a tag, the terminal device 1 is not set by the user as a server in the local area network. At this time, the central processing unit 11 transmits a link request message to the local area network through the network unit 13. In order to establish a connection with a server in the local area network; conversely, in the case of having the label of the server, it means that the terminal device 1 has been set by the user as a server in the local area network, Oh, the central processing The element 11 determines whether the connection request message sent by the network unit 13 is received, and if so, indicates that another device wants to establish a connection with itself, and at this time, the central processing unit 11 establishes a connection with the other device. .

Referring to FIG. 1 , when the terminal device 1 successfully establishes a connection with the other device, the other device transmits a selection data message to the terminal device 1 , and the selection data message includes at least one selected one. The data data name and the date of the update of the data data, the central processing unit 11 reads the data data 154 corresponding to the data material name and the update date of the storage unit 15 according to the content of the selected data message, and It is judged that the update date of the data data 154 corresponding thereto is later than the update date of the data data 154 corresponding to the other device, and if the update date of the data data 154 corresponding thereto is later, the content of the data data 154 is represented. If it is newer, the central processing unit 11 will transmit its corresponding data data 154 to the other device; if the update date of the data data 154 of the other device is later, the data data 154 representing itself is older. The central processing unit 11 transmits a request information message to the other device through the network unit 13 to receive the other The data 154 transmitted from the device is stored in the storage unit 15 so that the data 154 of the terminal device 1 and the data 154 of the other device can be maintained and maintained in the latest state. in this way, After the user returns home, the user can activate the data program 154 in the terminal device 1 and other devices in the home (eg, a personal computer) by starting the first synchronization program of the terminal device 1 (eg, a smart phone) in the hand. The data file 154 of the notebook computer is synchronized so that the data material 154 in the terminal device 1 can be shared with other devices. After that, the user can directly use the updated data data of the other device by directly using the other device. To carry out follow-up work, greatly improving the convenience of use.

In order to clearly disclose the method of data sharing and data synchronization of the foregoing embodiments, only the central processing unit 11 of the present invention has determined that the processing is in the local area network and the processing procedure of the first synchronization procedure 151 is started. For description, please refer to Figures 1 and 2: (201) determine whether it has a server tag in the local area network, and if so, proceed to step (202), otherwise, proceed to step (208); (202) Determining whether a connection request message of another device transmitted from the network unit 13 is received, and if yes, proceeding to step (203), otherwise, returning to step (202); (203) establishing a connection with the other device and determining whether to link Success, if yes, proceed to step (204), otherwise, return to step (202); (204) read a selected material message from the other device, proceed to step (205); (205) according to the content of the selected data message Determining whether the update date of the data data 154 corresponding to itself is later than the update date of the data material 154 corresponding to the other device, and if yes, proceeding to step (206), otherwise, proceeding to step (207); (206) data corresponding to itself Information 154 Passing the network unit 13 to the other device; (207) transmitting a request data message to the other device, and receiving the data data 154 sent from the other device, and storing the data data 154 in the storage unit 15; The network unit 13 transmits a connection request message and determines whether a connection is established with a server in the local area network, and if so, proceeds to step (209), otherwise, returns to step (208); (209) transmits a selection data message to The server proceeds to step (210); (210) determines whether the data data 154 or the request data message sent by the server is received, and if it is the data data 154, the process proceeds to step (211). If the data message is requested, the process proceeds to the step ( 212); (211) storing the data 154 to the storage unit 15; (212) transmitting its own data 154 to the server.

Thus, by the foregoing process, when the terminal device 1 is in the local area network of the home, it can share and synchronize with the data materials 154 in the plurality of other devices, so that the user can obtain the device regardless of which device is used. The latest data 154 can form a "private cloud" in the local area network, and at the same time, because the data 154 of the terminal device 1 is shared and synchronized in the "private cloud", In the server of the network provider, the confidentiality of the data 154 can be greatly improved, and the risk of leakage of the data 154 can be reduced. Further, in the foregoing embodiment, the user can enable the terminal device 1 or other device to actively activate the first synchronization program 151 every predetermined period of time to maintain the novelty of the data material 154 at any time.

In addition, in addition to the foregoing usage modes, as shown in FIG. 1, when the user goes out with the terminal device 1, but wants to share and synchronize the data data 154 with other devices in the home network in the home. The central processing unit 11 initiates another synchronization function (ie, executes the second synchronization procedure 152) when it is determined that the network is not in the area, and further searches for whether it has set the bit in the area network. The location of the server in the road, if so, the central processing unit 11 activates a web browser and establishes a connection with the server through the web browser, and the central processing unit 11 transmits a selection data message to the server. The server, if the central processing unit 11 receives the data 154 sent by the server, indicates that the data data 154 of the server is older (ie, the update date of the data data 154 is earlier than the server. Data data 154), which stores the received data 154 in the storage unit 15; if the central processing unit 11 receives the request information message from the server, it indicates its own According to the new content of the data 154 (i.e., the update date of the data data 154 is later than the data data 154 in the server), it transmits its own data 154 to the server, thereby causing the terminal device 1 to The data 154 in the server is kept in an optimal state, and the server can also synchronize the latest data 154 to other devices in the local area network, so that the user can directly go to other places after returning home. The latest data 154 is processed on the device.

In order to clearly disclose the method of data sharing and data synchronization of the foregoing embodiments, the following is only the processing flow of the central processing unit 11 of the present invention that determines that the network is not in the area and starts the second synchronization procedure 152. For the description, please refer to the first and third figures: (301) to determine whether the location of the server in the local area network to be connected is set, and if so, Going to step (302), otherwise, ending the process; (302) establishing a connection with the server through a web browser, and determining whether the connection is successful, and if yes, proceeding to step (303), otherwise, returning to step (301); 303) transmitting a selection data message to the server, proceeding to step (304); (304) determining whether the data data 154 or the request data message sent by the server is received, and if the data data is 154, proceeding to step (305). If the data message is requested, proceed to step (306); (305) store the data data 154 to the storage unit 15; (306) transmit its own data data 154 to the server.

In this way, when the user is not at home, the web browser in the terminal device 1 can still be used to establish a connection with the server in the local area network of the home to share and synchronize the data data 154 without having to wait until the user After returning home, data data 154 can be shared and synchronized to provide users with better experience.

In particular, although the foregoing embodiment uses the first synchronization procedure and the second synchronization procedure to represent different synchronization functions, in other embodiments of the present invention, as long as the synchronization function initiated by the terminal device is The steps and functions are in accordance with the aforementioned technical features, that is, the synchronous function referred to in the present invention, and the first is Chen Ming.
