Detailed ways

In order to more clearly illustrate the present invention, the present invention is further described below in conjunction with preferred embodiments and accompanying drawings. Similar components in the accompanying drawings are represented by the same reference numerals. It should be understood by those skilled in the art that the content specifically described below is illustrative rather than restrictive, and should not be used to limit the scope of protection of the present invention.

As shown in Figure 1, an embodiment of the present invention provides an information synchronization method between a mobile terminal and a server, which is applied to a mobile terminal, including: when it is determined that the mobile terminal is in an offline state: if the information is updated, the information in the terminal database is updated, and each information includes a name, data and a signature, wherein the signature is a terminal signature generated by the mobile terminal; when it is determined that the mobile terminal is changed from an offline state to an online state and there is at least one offline updated information whose signature is a terminal signature: an offline data synchronization request is sent to the server, so that the server generates a service signature and transmits it back to the mobile terminal; the signature of each offline updated information in the terminal database is updated according to the service signature, and each information with the updated service signature is sent to the server, so that the server updates the server database according to the received information.

In this embodiment, the terminal database set in the mobile terminal enables the mobile terminal to operate normally in an offline state: information is updated in the offline state and stored in the terminal database; when the mobile terminal changes from the offline state to the online state, the updated information is synchronized to the server database of the server through data synchronization initiated from the mobile terminal to the server, thereby realizing information synchronization. This embodiment can solve the problem in the prior art that the mobile terminal cannot work in an offline state because the mobile terminal does not store data, and effectively improves the working performance of the mobile terminal.

In a specific embodiment, an example of updating material information by taking inventory of materials in an enterprise is used for explanation, as shown in FIG1 .

In an offline state, when the mobile terminal takes inventory of materials, it updates the actual quantity of the materials to the information in the terminal database according to the actual inventory status of one or more materials, and generates a terminal signature as a signature.

When the mobile terminal changes from an offline state to an online state, for example, when the mobile terminal is moved from a warehouse without network signal coverage to an office space with network signal coverage, the mobile terminal connects to the network and sends an offline data synchronization request to the server.

The server receives the offline data synchronization request and generates a service signature to confirm synchronization, and sends the service signature to the mobile terminal.

The mobile terminal receives the service signature and updates the service signature to the signature of the information updated in the terminal database in an offline state, and sends the information with the updated service signature to the server, that is, the service signature generated synchronously by the server is updated to the information in the terminal database signed as the terminal signature.

The server stores the received information with updated service signature, that is, the information with updated data in offline state, in the server database, thereby realizing the synchronization of data updated by the mobile terminal in offline state.

It is worth noting that this embodiment only illustrates a specific implementation method of the present application through material information. The information synchronized between the mobile terminal and the server in the present application can be any specific information that is updated. Those skilled in the art should select appropriate application scenarios according to actual application requirements, and use information synchronization between the mobile terminal and the server as a design criterion, which will not be repeated here.

Considering that when the mobile terminal changes from an offline state to an online state, there is only a data synchronization method in one direction from the mobile terminal to the server. In an optional embodiment, the synchronization method also includes: receiving a synchronization request broadcast by the server, and querying whether there is information signed as the terminal signature; if so: sending an offline data synchronization request to the server, so that the server generates a service signature and transmits it back to the mobile terminal, updates the signature of the information signed as the terminal signature in the terminal database according to the service signature, and sends each updated information to the server, so that the server updates each updated information to the server database and updates the synchronization log. The synchronization log is used to record the synchronization information of the server database, such as recording the synchronization operation performed when a mobile terminal changes from an offline state to an online state.

In this embodiment, the synchronization request broadcasted periodically by the server further ensures that the information updated by the mobile terminal in the offline state is synchronized to the server database of the server, thereby realizing two-way offline data synchronization.

Specifically, as shown in Figure 2:

The server broadcasts synchronization requests periodically.

In this embodiment, the server is connected to at least one mobile terminal, and the server sends synchronization requests to each mobile terminal through a timed broadcast, thereby improving the query efficiency of the prior art of detecting whether each mobile terminal has offline information updates through server polling.

The mobile terminal receives the synchronization request and queries its own terminal database whether there is any offline information update, that is, information signed by the terminal. If not, the synchronization request is discarded, otherwise the offline information synchronization process is started: including: the mobile terminal sends an offline data synchronization request to the server; the server receives and generates a service signature to determine synchronization, and sends the service signature to the mobile terminal; the mobile terminal updates the signature in the offline updated information in the terminal database according to the service signature, and sends the updated information to the server; the server receives the information and updates it to the server database. The specific process is similar to the above embodiment and will not be repeated here.

It is worth noting that, no matter whether the mobile terminal initiates the offline data synchronization request to the server to start the synchronization process of offline updated information, or the mobile terminal initiates the synchronization process of offline updated information in response to the synchronization request broadcast by the server at a fixed time, only one of the two operations is performed in one offline data synchronization process.

Those skilled in the art should understand that the two simultaneous synchronization operations mentioned above are used to ensure that the information updated by the mobile terminal in an offline state is synchronized to the server database of the server. Those skilled in the art should set the implementation process of the two synchronization operations according to actual application requirements to avoid repeated synchronization operations, which will not be repeated here.

In an optional embodiment, the signature is a timestamp, which is used to indicate the synchronization status and synchronization time of the information.

In this embodiment, a timestamp is used as a signature, and the signature is not only used to represent the synchronization status of the information, but also the synchronization time of each information is represented by the timestamp. When the signature is a terminal signature, it indicates that the information is updated by the mobile terminal and is not synchronized with the server. When the signature is a service signature, it indicates that the information has completed the synchronization between the mobile terminal and the server and the timestamp is the synchronization time. It is worth noting that since the server generates a service signature based on the time when the synchronization request sent by the mobile terminal is received, the service signature generated by the server each time is unique, thereby avoiding confusion in the update order when multiple mobile terminals work together.

Taking into account the working conditions of the mobile terminal when it is online, in an optional embodiment, the synchronization method also includes: when judging that the mobile terminal is online: if the information is updated, updating the information in the terminal database and sending an online data update request to the server, the online data update request includes the name and data of the updated information, so that the server generates a service signature and transmits it back to the mobile terminal, and the server updates the name, data and service signature of the information to the server database; and updating the signature of the corresponding information in the terminal database according to the service signature.

In this embodiment, as shown in FIG. 3 , the update of material information in an enterprise is still described as an example.

In an online state, when the mobile terminal is taking inventory of materials, when the actual inventory situation of an item of material changes, the actual quantity of the material is updated to the information data of the terminal database, and a terminal signature is generated as the signature of the corresponding information.

At the same time, the mobile terminal sends an online data update request to the server, and the online data request includes the name and data of the information.

The server receives the online data update request and generates a service signature for confirming synchronization, and sends the service signature to the mobile terminal.

The mobile terminal receives the service signature and updates the service signature to the signature of the information in the terminal database.

At the same time, the server updates the corresponding information in the server database according to the received name and data and the generated service signature.

This enables synchronization of the updated information of the mobile terminal in the terminal database and the server database when the mobile terminal is online.

Taking into account that the server is connected to multiple mobile terminals and different mobile terminals may work at different times, there is a possibility of non-synchronization between different mobile terminals. In an optional embodiment, as shown in Figure 4, the synchronization method also includes: when it is determined that the mobile terminal is started or synchronized in response to an external operation: sending an online data synchronization request to the server, the online data synchronization request includes the name and signature of each information in the terminal database of the mobile terminal, so that the server queries the server database according to the name and signature of each information and encapsulates each information other than the name and signature into a synchronization data packet to send to the mobile terminal; receiving the synchronization data packet and updating each information therein to the terminal database.

In this embodiment, considering that different mobile terminals will synchronize with the server after updating information, that is, the server database of the server is all the information that has been recently updated. By initiating a synchronization request to the server when the mobile terminal is started or responding to an external operation, the problem of not being synchronized due to other mobile terminals updating information is avoided.

As shown in Figure 4, it specifically includes:

The mobile terminal sends an online data synchronization request to the server.

In this embodiment, the mobile terminal initiates a synchronization request to the server, and the online data synchronization request includes the name and signature of all the information in the terminal database.

The server receives the information and queries a server database according to the name and the signature to check whether the server database has information with a signature different from that of the terminal database.

In this embodiment, the server queries the terminal database in the server database through the name and signature of the information to see whether there is any unsynchronized information, and if so, synchronizes the information with the terminal database. Specifically, the server packages the information with different signatures into a data packet, and to ensure the security of the data packet, the server encrypts the data packet and compresses the encrypted data packet to facilitate the transmission of the data packet.

The mobile terminal receives the data packet and decompresses and decrypts the data packet to obtain the information to be synchronized obtained from the server database, and updates the terminal database according to the information to be synchronized to achieve synchronization between the mobile terminal and the server.

Similar to the above-mentioned information synchronization method applied to the mobile terminal, as shown in Figure 1, the present invention also provides a method for information synchronization between a mobile terminal and a server applied to the server, including: the server receives an offline data synchronization request sent by the mobile terminal, generates a service signature and sends it to the mobile terminal, so that the mobile terminal updates the service signature to the offline updated information in the terminal database, the information including the name, data and signature; the server receives the information with the updated service signature sent by the mobile terminal, and updates the server database according to the information.

The specific implementation process of this embodiment is similar to that of the above embodiment, and the above embodiment and the beneficial effects brought about thereby are also applicable to this embodiment, and the same parts will not be repeated here.

In an optional embodiment, as shown in Figure 2, the information synchronization method also includes: the server periodically broadcasts an offline synchronization request; the server receives the offline data synchronization request sent by the mobile terminal, generates a service signature and sends it to the mobile terminal, so that the mobile terminal updates the service signature to the offline updated information in the terminal database; the server receives the updated service signature information sent by the mobile terminal, updates the server database and updates the synchronization log according to the information.

In an optional embodiment, the signature is a timestamp, which is used to indicate the synchronization status and synchronization time of the information.

In this embodiment, a timestamp is used as a signature, and the signature is not only used to represent the synchronization status of the information, but also the synchronization time of each information is represented by the timestamp. When the signature is a terminal signature, it indicates that the information is updated by the mobile terminal and is not synchronized with the server. When the signature is a service signature, it indicates that the information has completed the synchronization between the mobile terminal and the server and the timestamp is the synchronization time. It is worth noting that since the server generates a service signature based on the time when the synchronization request sent by the mobile terminal is received, the service signature generated by the server each time is unique, thereby avoiding confusion in the update order when multiple mobile terminals work together.

In an optional embodiment, as shown in Figure 3, the information synchronization method also includes: the server receives an online data update request sent by the mobile terminal, the online data update request includes the name and data of the updated information; the server generates a service signature and transmits it back to the mobile terminal, and at the same time updates the name, data and service signature of the information to the server database, so that the mobile terminal updates the signature of the corresponding information in the terminal database according to the service signature.
