Detailed ways

The following will clearly and completely describe the technical solution of the present invention in conjunction with the accompanying drawings of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

Referring to Fig. 3, it is a system architecture diagram of an embodiment of the present invention. In the system architecture, a user data synchronization proxy server (hereinafter referred to as the proxy server) is set between the user data synchronization server and the user terminal, and the proxy server and the user data synchronization server Connect to the user terminal through the Internet through a local area network, such as WiFi (Wireless Fidelity, a wireless local area network based on the IEEE 802.11b standard) or Ethernet.

The proxy server can act as a proxy for the user data synchronization server to provide user terminals with user data synchronization services between user terminals. The proxy server can also synchronize user data with the user data synchronization server, thereby realizing user terminals, proxy servers and user data synchronization servers. User data synchronization between.

Preferably, the proxy server can be set up together with the home gateway device (such as a wireless router, a set-top box). For example, the existing home gateway device can be improved, and the user data synchronization proxy function can be added in it, so that the home gateway device can realize the above-mentioned proxy server The user data synchronization proxy function of .

Before the user terminal performs user data synchronization through the proxy server, it must first install the data synchronization proxy client, and register the data synchronization service on the proxy server. The proxy server can also register with the user data synchronization server, so as to perform user data synchronization with the user data synchronization server.

The processing operations of the user terminal involved in the following content are usually implemented by the user data synchronization client installed on the user terminal unless otherwise specified.

The registration process of the user terminal to the proxy server can be realized by using existing technologies, such as: the user terminal initiates a registration request to the proxy server through its data synchronization client, so that the user data synchronization service account (including user name, and including passwords), and provide user information (such as mobile phone number) and user terminal information (such as IP address, device identification) to the proxy server. For all user terminals that need to synchronize user data, their user data synchronization service accounts need to be bound with user information, so that user data can be synchronized among user terminals bound with the same user information. The bound user information is set when the user equipment registers for the user data synchronization service. Preferably, when a user terminal such as a mobile phone or a PDA of the same user submits the user's mobile phone number as the binding information when registering for the user data synchronization service. Of course, the registered user name can also be used as the binding information.

The registration process of the proxy server to the user data synchronization server can be realized by using the existing technology. The registration process of the proxy server usually occurs in the process of initializing the device after the proxy server is connected to the network.

Before the user terminal performs user data synchronization through the proxy server, it first needs to log in to the proxy server. In order to improve security, the proxy server can authenticate the user data synchronization service login request sent by the user terminal, such as authenticating the user name and password submitted by the user terminal, and allow it to use the data synchronization service after the authentication is passed; Otherwise, it is not allowed to use the data synchronization service.

Referring to FIG. 4 , it is a schematic flow diagram of a user terminal performing user data synchronization service login provided by an embodiment of the present invention. The flow may include:

Step 401, the user terminal sends a data synchronization service login request to the proxy server.

In this step, the user can send a data synchronization service login request to the proxy server by manipulating the user terminal. For example, by opening the proxy server login interface, and entering account information such as user name and password to log in. The data synchronization login request message carries relevant information of the user terminal, such as the IP address and identification of the user terminal.

In step 402, the proxy server performs login processing after receiving the login request.

In this step, after receiving the data synchronization service login request, the proxy server authenticates the login request, for example, verifies the user name and password carried in the login request. If the login request is verified, the user terminal is allowed to log in; if the login request is not verified (for example, the user name or password is entered incorrectly), the user terminal is refused to log in.

Step 403, the proxy server returns a data synchronization service login response to the user terminal.

In this step, if the proxy server allows the user terminal to log in, a login success response message is returned, and if the proxy server rejects the user terminal login, a login failure response message is returned.

Further, after receiving the login failure response message, the user terminal may send a data synchronization server login request to the user data synchronization server, so as to request to log in to the user data synchronization proxy server. This situation usually occurs when the user terminal is not yet registered on the proxy server, and thus its user data synchronization service login request is rejected.

Further, the proxy server can also send a broadcast signal in the local area network, so that the user terminal receiving the broadcast signal can automatically initiate synchronous login of user data. The automatic login process can include: the user terminal monitors the broadcast information in the local area network, and the proxy server The broadcast information sent may include the IP address of the proxy server, the port number of the registration service, supported data types (address book, information, photos, files, etc.); when the user terminal listens to the broadcast information sent by the proxy server, it sends The proxy server sends a data synchronization service login request, and its subsequent processing is the same as that described above, and will not be repeated here.

The proxy server and user data synchronization server provide user data synchronization services for user terminals that successfully log in to the server.

In order to describe the user data synchronization process provided by the embodiment of the present invention more clearly, the following describes in detail in conjunction with several specific application scenarios.

Embodiment one

The application scenario of Embodiment 1 is: terminal A and terminal B are in the same local area network, terminal A and terminal B have logged into the proxy server in the local area network, and the user data synchronization service accounts of terminal A and terminal B are bound to the same user Information, for example, terminal A is a mobile phone of a certain user, terminal B is a PDA of the same user, and their user data synchronization service accounts are bound to the mobile phone number of the user.

Step 501, terminal A sends a user data synchronization request to the proxy server, which carries user data to be synchronized and terminal A's user data synchronization service account information.

In this step, when the user data on terminal A changes, terminal A may send a user data synchronization request to the proxy server by itself. Of course, the user data synchronization request may also be actively initiated by the user operating on the terminal A. Among them, the user data on terminal A changes in various situations. For example, after the user modifies the address book on terminal A through the keyboard or screen operation of terminal A, the address book will change. When A is connected to a PC and imported into the personal photo album, it will cause the personal photo album to change. The user data to be synchronized usually needs to be specified in advance. Once the terminal A finds that the user data to be synchronized has changed, it will send a data synchronization request to the proxy server.

The user data synchronization request sent by terminal A may also carry its own related information, such as its own IP address or terminal identification.

Step 502, after receiving the user data synchronization request message, the proxy server determines that the target terminal to be synchronized is terminal B.

In this step, the proxy server queries the user data synchronization service account of terminal A and the user information bound to the account, and finds that the user data synchronization service account of terminal B is also bound to the user information, and terminal B has logged in to The proxy server therefore determines that terminal B is the target terminal for user data synchronization.

Step 503, the proxy server sends a user data synchronization request to terminal B, which carries the user data to be synchronized extracted from the data synchronization request sent by terminal A, so that terminal B updates the corresponding local user data.

Step 504, after the terminal B finishes updating the user data, it returns a success response message to the proxy server.

Step 505: After receiving the successful response message returned by terminal B, the proxy server returns a successful response message to terminal A.

The above steps 504-505 are optional steps.

Further, after the proxy server receives the data synchronization request from terminal A, it can also cache the user data to be synchronized, and the user data can be indexed by the user data synchronization service account information logged in by terminal A; The cached user data can be sent to the user data synchronization server, so as to realize the user data synchronization on the proxy server and the user data synchronization server with respect to the user data synchronization service account of the corresponding user.

In the above process, the user data synchronization request sent by terminal A may also carry the user information bound to the user data synchronization service account of terminal A to replace the user data synchronization service account information of terminal A. In this way, the proxy server can directly determine other logged-in user terminals that are also bound to the user information as target terminals for user data synchronization according to the user information carried in the request.

The above is described by taking terminal A already logged in to the proxy server as an example. If the user data on terminal A changes, but the proxy server is not currently logged in, terminal A can perform a login process, and then initiate a user data synchronization request to the proxy server after logging in to the proxy server.

In this embodiment, when the user data on a certain user terminal changes, the user data synchronization with other terminals bound to the same user is realized by accessing the proxy server in the local area network. Compared with the prior art The synchronization of user data is realized through the transfer of the network server, and the method of this embodiment is not limited by the speed of network access, which improves the efficiency of user data synchronization.

Embodiment two

The application scenario of Embodiment 2 is: terminal A has logged in to the proxy server, although terminal B has registered for the user data synchronization service on the proxy server, but cannot log in to the proxy server because it is not in the local area network where the proxy server is located (or for other reasons), Therefore terminal B logs into the user data synchronization server. And the user data synchronization service accounts of terminal A and terminal B are bound to the same user information.

Step 601, Terminal B sends a data synchronization request to the user data synchronization server, which carries the user data to be synchronized and the user data synchronization service account information of Terminal B, and may also carry information about the proxy server registered by Terminal B (such as the proxy server address or identification).

In this step, when the user data on terminal B changes, terminal B can send a user data synchronization request to the user data synchronization server by itself. Of course, the user data synchronization request may also be actively initiated by the user operating on the terminal B.

Step 602: After receiving the data synchronization request message, the user data synchronization server stores the user data to be synchronized extracted from the data synchronization request sent by terminal B, and sends the user data synchronization request to the proxy server, which contains the data to be synchronized User data and user data synchronization service account information of terminal B.

In this step, the user data synchronization server may send a user data synchronization request to the proxy server registered with terminal B according to the relevant information of the proxy server registered with terminal B carried in the received request message.

Further, the user data synchronization server may return a success response message to terminal B after sending the user data synchronization request to the proxy server.

In step 603, the proxy server determines that the target terminal to be synchronized is terminal A after receiving the user data synchronization request sent by the user data synchronization server.

In this step, the proxy server queries the user data synchronization service account of terminal B and the user information bound to the account, and finds that the user data synchronization service account of terminal A is also bound to the user information, and terminal A has logged in to The proxy server therefore determines that terminal A is the target terminal for user data synchronization.

Step 604, the proxy server sends a data synchronization request to terminal A, which carries the user data to be synchronized (the user data to be synchronized is obtained from the user data synchronization request sent by the user data synchronization server), so that the terminal A A updates the corresponding local user data.

Step 605, after the terminal A finishes updating the data, it returns a success response message to the proxy server.

The above step 605 is an optional step.

In this embodiment, when the user data on a certain user terminal changes, the user data between the user terminals bound to the same user can be updated in time by updating the changed data to the proxy server, thereby saving terminal synchronization. The waiting time improves the efficiency of user data synchronization.
