[0042] As an optional example, a screen sharing method of a mobile terminal is provided, such as Figure 3 As shown, the above method includes:

[0043] S302, the second mobile terminal receives a screen sharing request from the first mobile terminal, wherein the screen sharing request includes a mobile phone number on the second mobile terminal, and the screen sharing request also includes a first SIP INVITE message;

[0044] S304, the second mobile terminal parses the first SIP INVITE message, and when the session name field of the session header information in the first SIP INVITE message is a specific value, prompts that there is an invitation for remote desktop sharing, and when the session name field is empty, processes according to the default RCS video sharing service process;

[0045] S306, the second mobile terminal sends an instruction to receive screen sharing or an instruction to reject screen sharing to the first mobile terminal;

[0051] The second mobile terminal establishes an instant messaging session with the first mobile terminal;

[0052] The second mobile terminal sends a session message to the first mobile terminal, wherein the session message includes a specific field, and the specific field records the touch operation performed by the second mobile terminal on the screen interface of the first mobile terminal during screen sharing and the touch position of the touch operation.

[0053] As an optional example, during the screen sharing process, the method further includes:

[0054] The second mobile terminal sends a second SIP invite message to the first mobile terminal, wherein the second SIP invite message includes a touch operation performed by the second mobile terminal on the screen interface of the first mobile terminal during screen sharing and a touch position of the touch operation.

[0055] As an optional example, during the screen sharing process, the method further includes:

[0056] The second mobile terminal sends a pause instruction to the first mobile terminal, so that the first mobile terminal pauses recording interface content, or pauses sending recorded content to the second mobile terminal.

[0057] A specific example is used for illustration. The first mobile terminal and the second mobile terminal in the embodiment of the present application may be mobile communication terminals, and may be mobile terminals supporting Rich Communication Suite (RCS) services. The relevant standard information of RCS is GSMA RCC.71RCC.07

[0058] In the embodiment of the present application, the first mobile terminal and the second mobile terminal may be mobile phones. Taking a mobile phone supporting RCS as an example, mobile phone A may send a screen sharing request to mobile phone B, and mobile phone B responds to mobile phone A with an indication of receiving sharing, then mobile phone A may send the shared content to mobile phone B for display, and the user clicks on the screen content of mobile phone A displayed on mobile phone B to control the screen content of mobile phone A. The software part of the present application is divided into 6 modules. The modules may include: m1: desktop sharing service initiator control module. M2: desktop screen recording module. m3: video encoding module. m4: RCS protocol parsing module. m5: video decoding module. m6: desktop sharing service receiving end control module.

[0059] m1: Desktop sharing service initiator control module. This module is the user entrance for initiating remote desktop sharing. It has two functions: providing an operation interface for users to operate and responding to operations from remote mobile users.

[0060] m1-1 provides users with a process of inputting a phone number and initiating remote desktop sharing. For example, an interface can be provided for users to select a person in the address book, or to input a phone number, and then choose to initiate remote desktop sharing, or after a remote desktop sharing application is started, the user can choose to share his desktop with a remote phone.

[0061] m1-2 analyzes and processes the data information returned by the remote user operation. For example, if the user of mobile phone B clicks the screen, mobile phone B will send a message back, and mobile phone A will analyze and process the message and respond to the click.

[0062] m2: In the RCS video sharing service, this application consists of a desktop screen recording module, which is responsible for capturing the screen interface of mobile phone A and transmitting the data of the screen display content to m3 for video encoding.

[0063] m3: Video encoding module, responsible for encoding the data of the screen display content into a video stream according to a specific format, such as video encoded in H.264 format.

[0064] m4: RCS protocol parsing module. The RCS video sharing service uses the Session Initiation Protocol (SIP) to establish a session with mobile phone B. The relevant standard information of SIP is: IETF RFC3261. Mobile phone A will pass some parameters of video sharing through SIP invite message, and will update session information through SIP update message. In the embodiment of the present application, based on the extension of some optional fields in the protocol that were originally used only for manual analysis and not for program control, these extended fields are parsed to realize remote desktop sharing. For example, specific characters are used to inform that the request is a request to establish screen sharing.

[0065] m5: Video decoding module. Mobile phone B receives the video stream sent by mobile phone A, decodes it and displays it on the screen.

[0066] m6: desktop sharing service receiving end control module, which is responsible for receiving interface display and user screen operation (such as touching the menu on the screen interface) events, and sending the events back to mobile phone A.

[0067] The specific steps can be as follows Figure 4 As shown in steps S401 to S415.

[0068] process Figure 4 In S401: user A operates A's mobile phone and selects B's number as the target to start the remote desktop process. B's phone number can be directly entered, or the contact can be found from the address book or call log, and then B's phone number is automatically extracted as the target object. A clear desktop sharing operation menu is provided on the interface for the user to select and start the remote desktop process.

[0069] S402: Mobile phone A initiates an RCS video sharing service session invitation message to mobile phone B. In the message, the session name field of the session header information in the SIP INVITE is defined as a specific value to indicate that it is a special RCS video sharing service - remote desktop sharing service.

[0070] In the RCS service protocol, the session name field of the SIP INVITE message is not processed and is set to empty by default, that is:

[0071] "s="

[0072] In this embodiment, as an implementation example, it is set to "DesktopShare", that is, "s = DesktopShare"

[0073] S402: Mobile phone B receives A's RCS video sharing service session invitation message. S404: Mobile phone B parses the session name line in the message header to determine whether it is a remote desktop sharing service. If the name is a specific value for the implementation agreement, such as "s = DesktopShare", it indicates that it is a remote desktop sharing service. S405-1: Mobile phone B prompts the user on the screen that there is a remote desktop sharing invitation and waits for the user to operate. If the name is empty, S405-2: Process according to the default RCS video sharing service process.

[0074] S406: The user of mobile phone B touches the screen to accept the invitation, and mobile phone B sends a response message to mobile phone A.

[0075] S407: After mobile phone A receives the response message from mobile phone B, the RCS video sharing session is established and mobile phone A enters the remote desktop sharing state. Mobile phone A starts recording the screen and encodes it into a video stream in the session negotiation format and sends it to mobile phone B. Further,

[0076] S407-1, the remote sharing state of mobile phone A means that the front-end interface of mobile phone A will have a status prompt and a control entry to exit this state, and the background starts to enter the screen recording and video encoding state;

[0077] S407-2, the frame rate of screen recording can be set by the user according to the content of desktop sharing to ensure a better user experience. For example, if you want to provide the desktop of mobile phone A to mobile phone B to control mobile phone A, then the interface of mobile phone A will not change too quickly, and the screen can be recorded and encoded at a frame rate of 15fps; if it is a shared game, the screen can be recorded and encoded at the frame rate of the game video.

[0078] S407-3, the resolution parameters of the video encoding adopt the parameters determined in the session negotiation between mobile phone A and mobile phone B.

[0079] S408: Mobile phone B receives the video sent by mobile phone A and displays it on the screen according to the interface design of remote desktop sharing.

[0080] S408-1, remote desktop sharing, mobile phone A sends the screen recording of its own mobile phone, that is, the full-screen image displayed on the screen of mobile phone A. Although the video stream is compiled according to the resolution negotiated by the session, when it is sent to mobile phone B, a suitable display area still needs to be made according to the screen of mobile phone B.

[0081] S408-2, mobile phone B should be able to fully display the desktop image of mobile phone A.

[0082] At this point, based on the RCS video sharing service, mobile phone A sends the image of its screen to mobile phone B for display in real time.

[0083] S409, the user operates on mobile phone B. In step S408, the full screen interface on the screen of mobile phone A is displayed on the screen of mobile phone B. For example, if you click on the screen, the program will determine the touch point location area and perform different processing according to the area. Figure 5 shown. Figure 5 In the example, phone A sends the full screen image to phone B, and phone B displays the screen shared by phone A. If you click on the screen shared by phone A on phone B to form a touch point (solid point), the position of the point needs to be transmitted to phone A.

[0084] S410: If the touch point is within the full-screen image area of ​​mobile phone A, it is interpreted as an operation on mobile phone A. S411-1: Record the position coordinates of the touch point on the screen, process and package it into a touch event of the user on mobile phone A. The parameter information of the touch event includes the event type and position coordinates. The position coordinates of the touch point on the screen of mobile phone B should be combined with the position area of ​​the full-screen image of mobile phone A on the screen of mobile phone B, and further converted into the relative position ratio of the touch point in the full-screen image of mobile phone A. Furthermore, assuming that click Figure 5 The coordinates of the solid point touch point on the B phone are (540, 1500), and the A full screen image is (0, 100) in the upper left corner and (1080, 2020) in the lower right corner of the B screen area. Then the coordinates of this touch point on the A screen need to subtract an offset of 100 to become (440, 1500). Considering the difference in screen resolution between A and B, a scaling ratio must also be considered. Therefore, in order to accurately locate the position of the touch point on the A screen, this touch point uses a proportional value, x = 0.407 (i.e. 440 / 1080), y = 0.781 (i.e. 1500 / 1920).

[0085] Furthermore, the types of touch events on the screen by the user include click, double-click, long press, drag, etc., which are exactly the same as the touch event definitions of general Android phones / Iphone phones / Winphone phones.

[0086] S411-2: If the touch point is outside the full-screen area of ​​mobile phone A, it is interpreted as not an operation on mobile phone A, and is processed according to the touch of the current interface of mobile phone B.

[0087] S412, mobile phone B sends the user operation event to mobile phone A. Further, there are multiple ways to send the message back to A:

[0088] By using the session update message, the user operation event is filled into the specific field of the SIP UPDATE message, and a session update message request for the RCS service is sent to mobile phone A. In the RCS service framework, after a session is established, mobile phone A or B is allowed to send a session update message. In addition, the responding party can refuse the session update. When the receiving party refuses the session update, the current session will not be affected. Using this feature, two extended attributes are defined in the media information of the UPDATE message. The first one indicates that this is the type of remote user operation event, and the second one indicates the coordinates of the touch point. The example is as follows:

[0089] a=remote_action click

[0090] a=0.407 / 0.781

[0091] In the RCS service, multiple sessions are allowed to be established between users at the same time. When a video sharing service is established, a real-time chat session is established. In this way, the chat session can be used to send packaged user operation events. When A receives the chat message data, it parses the user operation time for remote desktop sharing according to the specific field information, and then forwards the event to the remote sharing application for processing.

[0092] The sip invite message of the RCS service is used to initiate a session invitation message again, and the user operation time is encapsulated into the data field of the message and returned to A.

[0093] S413, mobile phone A receives the SIP UPDATE message and needs to parse the description information of the message. When parsing the two new pieces of information in S8, it knows that this is a remote click operation of the user on mobile phone A, and saves the information of the user operation event.

[0094] S414, mobile phone A further analyzes the user operation event, replaces the corresponding coordinates transmitted by the SIP UPDATE message with the real coordinate positions on the current screen, and responds to the event according to the current application interface.

[0095] S415, mobile phone A sends a response message of the session update request to mobile phone B, rejecting the session update request initiated by mobile phone B. Preferably, according to the definition of the SIP protocol, a 48x response message can be selected. This type of message will not affect the current session, and will not initiate a session update, nor will it have any impact on the current session.

[0096] Through the above steps, mobile phone A can send its desktop to mobile phone B, and the user's operations on mobile phone B can be responded to on mobile phone A.

[0097] The advantage of the above embodiment is that users can directly initiate desktop sharing services based on mobile phone numbers, which greatly reduces the threshold for remote desktop between users. Ordinary users can initiate and use it at any time.

[0098] Moreover, this application is based on the framework of RCS services. RCS is a service that 5G terminals must support by default, and mobile terminals must support its basic protocols by default. Therefore, the technical difficulties of complex mobility management can be omitted, and it is easy to implement on the terminal; at the same time, this method can help operators add new business scenarios and increase revenue without modifying the network.

[0099] Through the description of the above implementation methods, those skilled in the art can clearly understand that the method according to the above embodiment can be implemented by means of software plus a necessary general hardware platform, and of course can also be implemented by hardware, but in many cases the former is a better implementation method. Based on such an understanding, the technical solution of the present invention is essentially or the part that contributes to the prior art can be embodied in the form of a software product, which is stored in a storage medium (such as ROM / RAM, a magnetic disk, or an optical disk), and includes a number of instructions for a terminal device (which can be a mobile phone, a computer, a server, or a network device, etc.) to execute the methods of various embodiments of the present invention.
