The embodiment of the present invention provides a method and apparatus for implementing file sharing in an IMS WEB conference. The preferred embodiments of the present invention are illustrated by the accompanying drawings, and are not intended to be construed as limiting. And in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. According to an embodiment of the present invention, a method for implementing file sharing in an IMS WEB conference is provided. As shown in FIG. 1 , the method mainly includes the following steps: Step 101: A WEB receives a user terminal sent by a user of a first user participating in a WEB conference. The shared message carries the page information of the shared file selected by the first user. Preferably, in this step, the first user can serve as the conference chairperson. Step 102: Display a page corresponding to the page information carried by the received shared message on the WEB interface of the user terminal of the first user. Step 103: Send the received shared message to the user terminal of each user who performs a WEB conference with the first user by using the IMS server. Step 104: Display a page corresponding to the page information carried by the shared message received by the user terminal of each user that performs the WEB conference with the first user on the WEB interface of the user terminal of each user. In the above process, step 102 and step 103 may be performed simultaneously, or step 103 may be performed first. In the step 101 of the process shown in FIG. 1 , the format of the page corresponding to the received page information is the display format supported by each user terminal participating in the WEB conference, that is, the shared file is converted into the user terminal of the first user. The format is supported by each user terminal and sent. Generally, the user terminal can support the picture display format. In order to increase the versatility of the shared file display, preferably, the shared file can be converted into a picture format. In step 101 of the flow shown in FIG. 1, the received shared message may carry page information of the set data amount according to the system setting. Since a file may be large, after the format conversion is performed in the user terminal of the first user, especially after conversion to the picture format, the data size of the file is increased by a multiple. Therefore, in the preferred embodiment of the present invention, in order to prevent the file information from being too large after the conversion, the message transmission is abnormal, and the shared file may be converted into a display format supported by each user terminal participating in the WEB conference. The display format supported by each user terminal participating in the WEB conference is converted one by one in units of the set data amount, for example, page-by-page conversion. According to a preferred embodiment of the present invention, in order to increase the security of the transmitted data, the user terminal of the first user may perform 64 base (Base64) encoding and then send the shared message when transmitting the shared message. In the step 103 of the process shown in Figure 1, the received shared message is sent to the user terminal of each user who performs the WEB conference with the first user through the IMS server. As shown in FIG. 2, the method includes the following steps: Step 201: After the shared message is encapsulated into a shared message in the Extensible Markup Language (XML) format, it is sent to the user terminal of the first user. Step 202: The user terminal of the first user forwards the shared message in XML format to the IMS server. Step 203: The IMS server forwards the shared message in the XML format to the user terminal of each user who performs a WEB conference with the first user. According to the above process, the shared file selected by the first user (such as the conference chairperson) is displayed in the first user and the user terminal of each user who performs the WEB conference with the first user. According to the method for implementing file sharing in the IMS WEB conference provided by the embodiment of the present invention, on the basis of implementing the file sharing through the foregoing process, the sharing between the participants can be further supported. In the preferred embodiment of the present invention, in order to support the operation of the currently displayed page by each user participating in the WEB conference, the whiteboard function is displayed when the page is displayed on the WEB interface of each user terminal; accordingly, in the first user After the WEB interface of the user terminal and the WEB interface of the user terminal of each user who performs the WEB conference of the first user respectively display the page, that is, after performing the above steps 101 to 104, as shown in FIG. 3, the following may further include the following Steps: Step 301: The WEB receives operation information about the currently displayed shared page sent by the user terminal of the second user participating in the WEB conference. In this step, the second user may be the first user who sends the shared file, or any user who participates in the WEB conference, or the user who meets the setting requirements, and may be flexibly set according to system control requirements. Moreover, the operation information is used to instruct the user terminal of each user to operate on the currently displayed shared page according to the operation information. Step 302: Send the received operation information to the user terminal of each user who performs a WEB conference with the second user through the IMS server. Step 303: The user terminal of each user who performs the WEB conference with the second user operates the currently displayed shared page according to the received operation information. In the above step 301, the operation information received by the WEB is sent by the second user that performs the setting operation on the currently displayed page of the shared file, and the step of the user terminal of the second user sending the operation information of the currently displayed page of the shared file includes: The user terminal of the second user monitors the setting operation performed by the second user on the shared file, determines the operation type information of the operation currently performed by the second user, and sends the information; wherein: the operation type information may be the second user for the current shared file. The display page performs specific operations, such as screenshots and text modification. In the preferred embodiment of the present invention, the WEB interface displays the shared file displayed by the whiteboard function, that is, the user can also view the page information, and can also perform operations on the page, for example, drawing, screenshot, modifying text, etc., for convenient understanding, The following further illustrates the process by taking the sketch of the meeting chair on the current display page as an example: After sharing a file, each member of the conference can operate on the WEB interface, such as drawing a line operation. The conference chair draws a line on the WEB interface, and sends the operation information to the WEB, where the operation information includes the operation type, and the position information of the drawn line on the current display page (such as the starting point position) and the thickness of the line. And other information. The WEB assembles the operation information into a custom message (such as a message in XML format) and sends it to the IMS server through the user terminal. The IMS server forwards the message to each conference member. After receiving the message, the conference member parses the message and draws the line to On the WEB page, to achieve synchronization of the operation. If the conference chairperson receives the operation message, after the corresponding operation is completed according to the operation message, the operation message may be further saved in the memory (used when saving the file). According to the method for implementing file sharing in the IMS WEB conference provided by the embodiment of the present invention, on the basis of the file sharing by the foregoing process, the shared file may be further supported for interoperability among the participants, in a preferred embodiment of the present invention. The page turning operation may be performed on the current display page. After the WEB interface of the user terminal of the first user and the WEB interface of the user terminal of each user who performs the WEB meeting with the first user respectively display the page, the above step 101 is performed. After the step 104, as shown in FIG. 4, the method includes the following steps: Step 401: The WEB receives the page turning operation information sent by the user terminal of the third user participating in the WEB meeting, and the page turning operation information carries the target page information after the page turning . In this step, the third user may preferably be the first user who sends the shared file, and may also be other users with the operation authority. And the page turning operation information is used to indicate that the user terminal of each user who performs the WEB meeting with the third user displays the page corresponding to the target page information carried by the page turning operation information in the respective WEB interface step 402, and receives the page. The page turning operation information is sent to the user terminal of each user who performs a WEB meeting with the third user through the IMS server. Step 403: The user terminal of each user who performs the WEB conference with the third user displays the page corresponding to the target page information on the respective WEB interface according to the received page turning operation information. In the above step 401, the page information after the page turning carried in the received page turning operation information may include the location information of the target page information in the shared file and the content of the target page, wherein the target page information is in the shared file. Location information can be matched by the corresponding XML message The file identifier is set, and the corresponding XML file can be determined according to the configuration file identifier, thereby determining the target page information. According to a preferred embodiment of the present invention, before the step 402 is performed, before the page turning operation information to be received is sent to the user terminal of each user who performs the WEB conference with the third user, the method further includes: determining that the page turning operation information is carried The target page information is stored locally on the WEB. According to the preferred embodiment, when each user terminal participating in the WEB conference operates the shared file, it is first determined that the WEB locally saves the target page, and further, the target page can be controlled to be displayed on the WEB interface of each user terminal. If the corresponding target page is not saved locally in the WEB, the corresponding target page needs to be obtained from the first user terminal that sends the shared file, and then the synchronization operation of each operation member in the WEB conference is implemented. When the document sharing data conference is closed, the first user can save the shared file to the local, and when saving, the page information saved in the memory can be sent to the control in units of pages, and the control saves the information as a customized file. Format, unsaved page information in memory is extracted from the original shared file and converted to a custom file format. If the shared file needs to be further sent to the participating members, the saved customized format file is sent to each participating member. In the above embodiment, the process in which the IMS server receives the shared file sent by the user terminal of the first user participating in the WEB conference is preferably applicable to a file format such as DOC/DOT/RTF/XLS, and the file is usually in the user terminal. Display page by page. The technical solution provided by the embodiment of the present invention, in a specific application, the client on the user terminal side can use the "SIP + Hypertext Transfer Protocol" based on the browser and server (B/S) architecture. , HTTP) "The mode communicates with the network side, that is, the interaction between the client on the user terminal side and the IMS server on the IMS core network side passes the SIP protocol. The basic flow is: The user terminal client sends a SIP request to the IMS server, and receives the IMS server. The returned SIP response is unpacked and the business function is completed through multiple SIP requests/responses conforming to the business process. The display interface of the shared file (such as the WEB interface) completes the interface presentation through HTTP and WEB interaction through the browser. From the architecture, the client SIP protocol stack supports the service application, implements through the control mode, and follows the 3GPP IMS authentication method and process, and complies with relevant technical standards. In terms of implementation, WEB does not participate in the judgment of business logic, so that users can open WEB sessions by opening a browser, providing convenient communication methods, and providing a possibility for adapting to the cloud computing environment in the future. Moreover, with the emergence and application of technologies such as Asynchronous JavaScript and XML (Asynchronous JavaScript and XML, AJA) X, the technical solution provided by the present invention can realize the IMS WEB conference environment through the interaction between the script and the control in the specific implementation.

Step 602: Pass information such as a path of the DOC file selected by the user to the WEB. Step 603: The WEB passes information such as a file path to the control and caches the information. Step 604: Determine, by the control, the DOC file according to the received path information, and convert the DOC file from the first page to the picture information by using a virtual printing technology. Step 605: The control returns the picture information to the WEB after performing base64 encoding. Step 606: After receiving the picture information, the WEB displays the picture information in the form of a whiteboard background image on the WEB interface of the conference chairperson. Step 607: The file information is assembled into a custom information in an XML format and sent to the control. Step 608: Send, by the control, a custom message in an XML format to the IMS server. Step 609: After receiving the customized message in the XML format of the shared file, the IMS server sends a file sharing notification to the control in the user terminal of the member participating in the WEB conference. Step 610: The control of the user terminal forwards the file sharing notification to the WEB. Step 611: The WEB parses the notification message, and displays the corresponding page display content on the WEB interface of the conference member. In this embodiment, the user terminals of each participating member display the picture information of the shared file through the WEB page therein, and are preferably displayed on the WEB interface developed by Flex in the form of a whiteboard background image. In this embodiment, due to the system, the conference member page loading speed is not the same. Preferably, when receiving the file sharing notification of the IMS server, each conference member should first cache the page information, after the page is normally loaded, Display page information to prevent the page from appearing when the page has not been loaded. After the above steps, the conference chairperson and conference members can display the information of the shared files page by page. At this time, the conference chairperson and conference members can use the whiteboard function to perform operations on the WEB interface, such as drawing, screen capture, adding text, and turning pages. As shown in Figure 7, the chairman of the meeting After the file is operated (for example, the page turning operation is taken as an example), the process between the participating members includes: Step 701: The meeting chairperson performs a page turning operation on the shared file through the WEB interface. Step 702: Send operation information of the user to perform a page turning operation to the WEB. Step 703: The WEB determines whether there is target operation object information in the cache according to the operation object information included in the operation information. If yes, step 707 to step 710 are directly performed. If not, steps 704 to 710 are performed. Step 704: Request, from the control, page information (ie, target operation object information) of the conference chair operation. Step 705: The control sends the corresponding page information to the WEB by performing Base64 encoding. Step 706: After receiving the page information, the WEB displays the page information in the form of a whiteboard background image on the WEB interface of the conference chairperson. Step 707: The control sends the page information to the IMS server. Step 708: The IMS server sends the page information to the control in the user terminal of the member participating in the WEB conference. Step 709: The control forwards the page information to the WEB. Step 710: The WEB displays the page information on the WEB interface of the conference member. In the above embodiment, after the conference chairperson performs the page turning operation, the page information of the page turning is sent to the user terminal of each participant through the IMS server and displayed, so that the user terminals participating in the WEB conference can implement the meeting chairperson. Synchronous operation. Moreover, the conference chairperson can save the shared page information for the next use. After the document save operation, the chair will send all the cached page information to the control in units of pages, and also convert the image information to the undisplayed page, and save it in the same custom file.
