Detailed ways

In order to make the purpose, technical solution and advantages of the present invention clearer, the following examples are given to further describe the present invention in detail.

As shown in FIG. 2 , the mobile terminal of the first embodiment of the present invention includes a storage module 21 , a short message sending and receiving module 22 , and a data collection and analysis module 23 . Preserve personal data in storage module 21, as address book, memo, schedule etc., can also allocate a storage space in storage module, be used for keeping the mark that represents whether each piece of personal data has been backed up, this storage space can be independent A piece of storage space, or scattered in each corresponding personal data storage space. Before each piece of personal data is not backed up, the storage space corresponding to the piece of personal data is marked as not backed up; after the piece of personal data is backed up, the corresponding mark in the storage space is changed to backed up . The storage module may be a Subscriber Identity Module (Subscriber Identity Module, SIM) card or a memory of a mobile terminal. The short message sending and receiving module 22 is responsible for sending short messages to the network and receiving short messages sent from the network. The data collection and analysis module 23 includes a data collection module 231 and a data analysis module 232. The data collection module 231 is responsible for collecting user's personal data, and converting it into a short message in a specific format, and then sending it to the short message sending and receiving module. The data parsing module 232 parses the short message in the specific format after the short message sending and receiving module receives the short message in the specific format, parses out the personal data therein, and stores it in the storage module 21 .

As shown in FIG. 3 , the server-side network-side device of the first embodiment of the present invention includes a short message sending and receiving module 31 , a data collection and analysis module 32 , and a storage module 33 . The short message sending and receiving module 31 receives the short message sent by the mobile terminal through the network, and sends it to the data collection and analysis module 32 for processing, and can also send the short message sent from the data collection and analysis module 32 to the mobile terminal through the network. The data collection analysis module 32 is specifically an application server at the server end, which analyzes and processes the personal data short message transmitted from the short message sending and receiving module 31, and then stores it in the storage module according to different identification numbers and different data types In 33, also according to the short message that the request that short message sending and receiving module 31 receives receives personal data, extract the personal data that this short message requests to obtain from storage module 33, and convert into specific format short message and send to short message sending and receiving Module 31. The storage module 33 is generally a data server, responsible for storing the personal data transmitted by the data collection and analysis module 32, and providing personal data to related modules such as the data collection and analysis module.

The network side device at the server side may further include a web (WEB) server query system 34 . After the user enters the identification number and corresponding password through the WEB browser, an HTTP query request is sent to the WEB server query system. The WEB server query system judges whether the identification number and the corresponding password in the query request are correct. The browser sends out the content of personal data, otherwise, an error message is sent to the user's WEB browser.

Next, in the method of the first embodiment, the personal data of the first mobile terminal is saved to the server, and then the second mobile terminal acquires the personal data saved by the first mobile terminal from the server.

In the present invention, the second mobile terminal may be the same as or different from the first mobile terminal. If both are the same, it means they are the same mobile terminal using the same SIM card number or different mobile terminals using the same SIM card number; if they are different, it means they are the same mobile terminal using different SIM card numbers Mobile terminals, or different mobile terminals using different SIM card numbers.

FIG. 4 is a schematic flowchart of the first embodiment of the present invention. The flow process of the first embodiment of the present invention is as follows, including:

Steps 401 to 402 are the process of saving the personal data on the first mobile terminal to the server;

Steps 403 to 405 are the process for the second mobile terminal to obtain the personal data of the first mobile terminal from the server.

Step 401, after receiving the instruction of backing up personal data, the data collection and analysis module of the first mobile terminal collects the personal data in the storage module and converts it into a short message in a specific format, and the short message sending and receiving module sends the short message in the specific format The message is sent to the server side.

In the present invention, the instruction for backing up personal data has the following situations:

1. Immediate backup method. The mobile terminal immediately collects personal data according to the user's instruction and sends it to the server.

2. In the specified date and time mode. The mobile terminal collects personal data after the time specified by the user and sends it to the server.

3. Specify the incremental method. After the personal data in the mobile terminal increases by a specified amount, for example, after the personal data increases by 100 pieces, the mobile terminal starts to collect the personal data and sends it to the server.

4. Specify the way to send periodically. After setting the start date and time interval, the mobile terminal regularly collects personal data according to the set interval and sends it to the server.

The present invention can collect all personal data and send them to the server, or only collect unbacked personal data and send them to the server. The implementation scheme of collecting only personal data that has not been backed up is as follows: First, judge which personal data has not been backed up according to the marks in the storage space; then, collect those personal data that have not been backed up, convert it into a short message in a specific format and send it to server side, and change its corresponding flag to have been backed up.

The specific format short message includes the requested service code, identification number, password and personal data, and spacers can also be added between these contents. The identification number may be the number of the first mobile terminal, or an agreed number, such as the number allocated by the server. The following is an example of a short message in a specific format:

TJHM#

13899999999#

123456#

Name 1, phone number 1, note 1#

Name 2, phone number 2, note 2#

 …

Name n, phone number n, remarks n#

Among them, "TJHM" is the service code, which means adding personal data to the server; "#" is the spacer between each part of the content; "13899999999" is the identification number, here the number of the first mobile terminal is the identification number; "123456" is the user password; the following is personal data, here we take the address book as an example, including fields such as name, phone number, and remarks, and each field is separated by a comma. It should be pointed out that the specific format short message in the present invention is not limited to the specific format in the above example.

Since the number of characters contained in each short message is limited, the present invention converts personal data into multiple short messages in the same specific format and sends them out successively when the content of the personal data exceeds the capacity of one short message in a specific format. For example, if there are 45 pieces of personal data to be backed up, and each short message in a specific format can only accommodate 10 pieces of personal data, then divide the 45 pieces of personal data into 5 short messages in a specific format, and each short message contains 10, 10 , 10, 10 and 5 pieces of personal data.

Step 402: After receiving the short message sent by the first mobile terminal, the short message sending and receiving module at the server side sends the short message to the application server, and the application server parses the short message and stores the content in the database server .

The specific format short message is sent from the first mobile terminal, passes through the network, and is received by the short message sending and receiving module at the server end. The short message sending and receiving module sends the short message to the application server, and the application server analyzes the sent one or more short messages in a specific format, and saves the parsed personal data to the database server according to the user number and different data types . For safety reasons, there may also be an encryption step in the preservation process.

Taking the above short message in a specific format as an example, the application server parses the short message and learns from "TJHM" that the short message is to add personal data on the server side. Get the identification number and corresponding password from "13899999999" and "123456", and establish a data record in the database server based on the identification number, and store the personal data in the short message in different data types in the data record If the data record of the identification number already exists in the database server, judge whether the password is correct, and if it is correct, continue to write personal data in the data record of the identification number, otherwise the database will not be operated. As a result, multiple data records are formed on the database server, each data record corresponds to a different identification number, and personal data is stored in the data record, and the personal data in each data record is distinguished by a key field Composed of multiple pieces of personal data.

For each piece of newly parsed personal data, judge according to the key field. If there is personal data in the same key field in the data record of the identification number, the personal data will not be saved, otherwise the personal data will be saved. Taking the address book above as an example, the key fields are name and phone number. If there is a piece of personal data with the same name and phone number in the newly parsed personal data and data records, it means that this piece of personal data is the same, then it will not be saved. The piece of personal data, otherwise the piece of personal data is stored in the data record with the corresponding identification number. This saves a lot of storage space.

The server side can also send a confirmation short message to the first mobile terminal by the short message sending and receiving module after successfully saving the personal data.

Step 403: After receiving the instruction to obtain personal data, the second mobile terminal sends a request short message requesting to obtain personal data to the server.

After the second mobile terminal receives the instruction from the user to acquire personal data, it sends a short message requesting to acquire personal data to the server, and the short message includes the identification number and password of the personal data to be acquired. The following is an example of a request short message:

HQHM#

13899999999#

123456#

Among them, "HQHM" is the service code, indicating that personal data is to be obtained; "13899999999" is the identification number of the personal data to be obtained, which is the number of the first mobile terminal in this example; "123456" is the user password; "#" is the spacer between the contents of each section. Likewise, the request short message of the present invention is not limited to the specific form in the above example.

Step 404, after receiving the request short message from the second mobile terminal, the server side judges whether the identification number and password are correct, if correct, then sends the personal data to be obtained in the request short message to the second mobile terminal, otherwise makes an error process .

After receiving the request short message from the second mobile terminal, the server side learns that it is a request to obtain personal data according to the service code in the short message. Judging whether the identification number and corresponding password in the request short message are correct, if correct, the application server extracts the corresponding personal data from the database server and converts it into a specific format short message, if the personal data exceeds the capacity of a specific format short message , then divided into multiple short messages with the same specific format, and sent to the second mobile terminal successively by the short message sending and receiving module; if it is incorrect, make corresponding error handling.

Taking the request short message in step 403 as an example, the application server learns from "HQHM" that the request short message is to obtain personal data on the server side. Obtain the identification number and corresponding password from "13899999999" and "123456", and then judge whether the data record of the identification number exists in the database server and whether the corresponding password is correct. If all are correct, the application server extracts the data record of the identification number from the database server and form one or more personal data short messages in a specific format according to the capacity requirements of the short message, and send them to the short message sending and receiving module on the server side, and the short message sending and receiving module sends it to the second mobile terminal through the network; if If there is no data record of the identification number in the database server or the password is incorrect although there is a data record of the identification number, the application server will make corresponding error handling.

Step 405: After the short message sending and receiving module of the second mobile terminal receives the personal data short message sent by the server, the data collection and analysis module analyzes it, and saves the personal data in the storage module.

If there are multiple personal data short messages sent by the server, the data collection and analysis module of the second mobile terminal analyzes these personal data short messages respectively, and then saves the personal data in the storage module.

In order to save storage space, the second mobile terminal does not store the same personal data item repeatedly. Also judge each piece of newly parsed personal data according to the key fields. If the newly parsed personal data has the same key field as that in the storage space of the second mobile terminal, the piece of personal data will not be saved, otherwise the The pieces of data are stored in the memory module.

After the first mobile terminal saves the personal data to the server, the content of the personal data can be queried through the WEB server query system at the server. The user submits a query request to the WEB server query system through a WEB browser, and the query request includes an identification number and a password. The WEB server query system first judges whether the identification number and the corresponding password in the query request are correct, and if correct, sends the content of personal data to the user's WEB browser, otherwise, performs error handling, such as sending an error prompt to the user's WEB browser information etc.

The present invention may also include the user signing process for the service, that is, the registration process, before the transfer of personal data begins, and the user termination process for the service, that is, the cancellation process, after the transfer of personal data ends.

The registration process includes the following steps before transferring personal data: the first mobile terminal sends a registration short message to the server; the server performs registration operation after receiving the registration short message, and sends a confirmation short message to the first mobile terminal.

The logout process may be initiated by the first mobile terminal or by the second mobile terminal after the transfer of personal data is completed. The logout process includes the following steps: the first mobile terminal or the second mobile terminal sends a logout short message to the server; the server performs a logout operation after receiving the logout message, and sends a confirmation message to the first mobile terminal or the second mobile terminal information.

The server side is generally provided by the content provider. The network between the mobile terminal and the server is generally provided by a mobile network operator, and the network includes a short message center (SMSC) and a short message gateway. The SMSC and the mobile terminal are connected through a wireless interface, and the short message gateway and the server are connected through the Internet (Internet) or a dedicated line.

The second embodiment of the present invention adds a SYNC ML protocol module that supports the Synchronization Markup Language (SYNC ML) protocol on the mobile terminal, and this module reads all multimedia messages and Emails on the mobile terminal, and collects changes since last collection Personal data and convert it into a message (MSG) in a specific encoding format, and then send the MSG to the Wireless Application Protocol Gateway (WAP GW) through HTTP/SYNC ML.

As shown in FIG. 5 , the apparatus involved in the second embodiment includes a mobile terminal 51, a WAP GW 52, a network server 53 and a personal computer (PC) 54. The mobile terminal includes a storage module 511 and a SYNC ML protocol module 512. Multimedia messages and Emails are stored in the storage module 511, and the storage module 511 may include multiple folders such as an inbox, an outbox, and a draft box, wherein the inboxes store multimedia messages and Emails received by the mobile terminal. , the outbox stores multimedia messages and emails sent by the mobile terminal, and the draft box stores multimedia messages and emails that are being edited or not sent by the mobile terminal. The SYNC ML protocol module 512 reads multimedia messages and Emails in all folders in the storage module 511 according to the application programming interface (API) provided by the mobile terminal, and converts them into MSG in a specific encoding format, and then bears the weight of the HTTP protocol or in the HTTP protocol Superimposed on the SYNC ML protocol, the MSG in a specific encoding format is sent to the network server via WAPGW. Since the SYNC ML protocol module is based on the SYNC ML protocol, and the SYNC ML protocol can achieve incremental synchronization of data, the SYNC ML protocol module can collect personal data that has changed since the last collection without having to collect all personal data .

WAP GW 52 forwards the specific encoding format MSG sent from the mobile terminal to the network server. During the forwarding process, WAP GW 52 may not understand the content of MSG in a specific encoding format, and transparently forward it. Because WAP GW forwards MSG in specific encoding format to the network server through HTTP protocol and according to the IP address of the network server, it does not need to know the target mobile phone number or other content contained in MSG, so WAP GW is transparent to MSG in specific encoding format. Forward.

The web server 53 includes at least a message receiving module 531 , a data storage module 532 , and a WEB server query system 533 . Wherein the message receiving module 531 supports the SYNC ML protocol, and the specific encoding format of the multimedia message and Email, this module receives the data of the specific encoding format forwarded by the WAP GW, and extracts the multimedia message or Email therefrom, and then saves it to the data storage module 532 middle. The data storage module 532 saves the multimedia messages and emails of different mobile terminals transmitted by the message receiving module 531, and provides corresponding multimedia messages and emails to the WEB server query system. The function of the WEB server query system 533 is the same as that of the WEB server query system in the first embodiment, and will not be repeated here.

The user can send an HTTP query request to the WEB server query system through a personal computer (PC) 54, and the PC 54 receives and displays the query results sent by the WEB server.

As shown in Figure 6, the process of the second embodiment of the present invention is as follows:

Step 601, after receiving the instruction for backing up personal data, the SYNC ML protocol module 512 of the mobile terminal collects the personal data in the storage module 511, converts it into MSG in a specific encoding format, and sends the MSG in the specific encoding format to WAP GW.

The mobile terminal provides an API interface for reading multimedia messages and Emails, and the SYNC ML protocol module 512 reads multimedia messages or Emails from the mobile terminal according to these interfaces, and then converts them into MSG in a specific encoding format. A specific encoding format message can include multiple multimedia messages or Emails, and unlike the short message in the first embodiment, the capacity of the specific encoding format message in the second embodiment has no upper limit, so the MSG in the second embodiment can Accommodates multiple multimedia messages or Emails.

The encoding format of each multimedia message or Email in the specific encoding format MSG includes the following fields:

1.BEGIN: MSG is the initial sign of the MSG;

2. ID is the identification of MSG. The content of this field is assigned a value by the multimedia message center or Email server, such as "ID: 1022". The multimedia message or Email in the inbox has this ID value, and the value in the outbox and The multimedia message or Email in the draft box does not have this ID value, so the ID field may not be required for the specific encoding format MSG;

3. FROM is the identifier of the sender, which represents the sender of the MSG. For example, if the mobile terminal number of the sender is 13012345678, then this field is "FROM: 13012345678";

4. TO is the recipient's identifier, which represents the recipient of the MSG. For example, the mobile terminal number of the recipient is 13987654321, then this field is "TO: 13987654321";

5. TYPE is the type of MSG, including multimedia message, short message, and Email, which are represented by MMS, SMS, and EMAIL respectively. For example, if the MSG type is multimedia message, the field is "TYPE:MMS";

6.FOLDER is the location where MSG is stored in the mobile terminal, that is, the folder where it is located, including draft box, inbox, and outbox, which are represented by DRAFT, INBOX, and SENT respectively. For example, the MSG is stored in the mobile terminal draft box in , the field is "FOLDER:DRAFT";

7. TIME is the creation time of MSG, which can be expressed in many ways. Here, take the format of "year/month/day hour:minute:second" as an example, in which the year occupies four digits, and the month, day, hour, minute, and second each It occupies two digits, and there is a gap between the day and the hour. For example, when the MSG was created at 8:54:55 on April 28, 2004, the field is "TIME: 2004/04/2808:54:55 "; the TIME field may not be required for the specific encoding format MSG;

8. SUBJECT is the subject of MSG. The content of this field is prompted by the SYNC ML protocol module to input the user. If the user does not enter any content, the SYNC ML protocol module can assign a default value to this field, including blank content. For example, the subject of MSG is "First test MMS", the field is "SUBJECT: First test MMS";

9. DATA is the MSG data content, here is an example description in xml language, if the MSG of a multimedia message includes a text file HelloWorld.txt, a voice codec file SmileyFace.amr, a picture file SmileyFace.gif, and a synchronous multimedia synthetic language file HelloWorld.smil and other files, the DATA field includes the name, type and data in each file, for example, the text file HelloWorld.txt is as follows:

<File>

<FileName>HelloWorld.txt</FileName>

<FileType>text/plain</FileType>

<FileData>

Hello, world!

</FileData>

</File>

Wherein the xml language used is a well-known technology, and will not be repeated here.

10. END: MSG is the end mark of MSG.

As we all know, SYNC ML technology is formulated by the Open Mobile Alliance (OMA), which is a standard protocol for data synchronization. This protocol can realize incremental synchronization of data, that is, during the synchronization process, only the changed part of the data is transmitted instead of all the data, so the efficiency is relatively high. The SYNC ML protocol module in this embodiment can collect personal data that has changed since the last collection, instead of collecting all personal data, thereby improving the efficiency of backing up personal data.

Step 602, WAP GW 52 forwards the MSG in the specific encoding format to the network server 53 after receiving the above-mentioned MSG in the specific encoding format.

WAP GW 52 forwards the specific encoding format MSG sent from the mobile terminal to the network server. In the forwarding process, WAP GW 52 does not need to understand the content of MSG in a specific encoding format, and transparently forwards it. During the sending process, SYNC ML is based on the IP protocol. After the client configures the IP address of the web server, it can send it to the web server.

Step 603, after the message receiving module 531 on the network server 53 receives the MSG, save the content in the MSG to the data storage module 532, and send a response message to the WAP GW 52.

The message receiving module 531 on the network server 53 receives the MSG forwarded by the WAP GW 52, and saves the multimedia message, short message or Email in the MSG in the data storage module 532 according to the identification number of the mobile terminal. The process in step 402 in one embodiment is similar, so it will not be repeated here. After successfully storing, the web server 53 sends a MSG storage success response message to the WAP GW 52. If the storage is unsuccessful, the web server 53 can also send a storage failure response message to the WAP GW. This indicates that the storage failure response message can be Further include the reason for the storage failure.

Step 604, WAP GW forwards the response message to the mobile terminal, and the mobile terminal displays the response message to the user.

After receiving the response message sent by the network server 53, the WAP GW 52 forwards the response message to the mobile terminal.

After receiving the response message forwarded by the WAP GW, the mobile terminal displays the content of the response message to the user. If the storage is successful, the user sees a message indicating that the storage is successful, and if the storage is not successful, the user sees a message indicating that the storage failed, and even further storage failure reasons.

After the personal data in the mobile terminal is successfully saved to the network server, the user can browse the personal data in the network server through the PC, and the process is described in steps 605 and 606 .

Step 605, PC 54 submits a query request to the WEB server query system according to the user's instruction.

The user submits a query request to the WEB server query system through the WEB browser on the PC. The query request includes the identification number and password of the mobile terminal, and may further include restrictions on the query content, such as multimedia messages to be queried.

Step 606, the WEB server query system sends the requested content to the PC according to the received query request.

The WEB server query system receives the query request sent by the PC, and judges whether the identification number and the corresponding password in the query request are correct, and if correct, extracts the content requested by the user from the data storage module 532, and then sends it to the PC Otherwise, do error handling, such as sending an error message to the WEB browser on the PC.

The above descriptions are only preferred embodiments of the present invention, and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included in the scope of the present invention. within the scope of protection.
