Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1, fig. 1 is a flowchart of an information transmission method according to an embodiment of the present invention, where the method is applied to a first terminal, and as shown in fig. 1, the method includes the following steps:
step 101: the first drawing image information is transmitted to the second terminal through the first RTP media stream.
The first drawing image information is input on the first terminal by a first terminal user in the video call process of the first terminal and the second terminal. A first RTP (Real-time Transport Protocol) media stream for transmitting drawing image information is different from a second RTP media stream for transmitting video call information between a first terminal and a second terminal, i.e., the first RTP media stream and the second RTP media stream are used for different service functions. The second RTP media stream may be understood as an existing telephony RTP media stream.
Understandably, the first terminal can be selected as a calling end, and the second terminal is a called end; or, the first terminal may be selected as a call called terminal, and the second terminal is a call calling terminal. The video call may be selected as a Voice over IP (VoIP) call.
In step 101, a video call connection has been established between the first terminal and the second terminal, and a shared drawing function has been established. The establishment of the shared drawing function can be initiated by a calling end of a call or a called end of the call. The drawing sharing function of the first terminal and the second terminal may be implemented by a specific Software Development Kit (SDK) or a plug-in, which is not limited in the embodiments of the present invention.
In the embodiment of the invention, the painting image information formed in the video call process is directly transmitted through the first RTP media stream which is independent relative to the second RTP media stream, and the second RTP media stream is the call RTP media stream and is used for transmitting the video call information, so that the transmission of the corresponding painting image information can be realized on the premise of not influencing the video call, and compared with the prior art of transmitting the painting image information by using an MSRP tunnel, the painting image information can avoid the generation of additional signaling overhead caused by frequently transmitting the MSRP information, thereby saving network resources.
Further, since the drawing image information is sent through the MSRP messages one by one, problems of too low frequency of sending messages, packet loss of sending messages, too fast frequency of sending messages, and the like may occur, and if the frequency of sending messages is too low or the frequency of sending messages is lost, the drawing track is not consistent enough, or if the frequency of sending messages is too fast, a large amount of work of encapsulating messages, sending and receiving messages, analyzing messages, and the like may occur, which has a high requirement on the computing capability of the software and hardware of the terminal, and may generate extra power consumption and flow cost, so that it is difficult to ensure high business experience by sending the drawing image information through the MSRP messages one by one. However, by sending the drawing image information through the RTP media stream in this embodiment, these problems can be completely avoided, so that the drawing smoothness is greatly improved, the calculation amount of software and hardware of the terminal is reduced, and good service experience is ensured.
In at least one embodiment of the present invention, optionally, the information transmission method may further include:
receiving second drawing image information sent by a second terminal through a first RTP (real time protocol) media stream;
displaying the second drawing image information;
wherein the second drawing image information is input on the second terminal by the second terminal user during the video call between the first terminal and the second terminal.
Therefore, the interaction of the corresponding drawing image information between the first terminal and the second terminal can be realized.
In sharing a drawing, it is common to default that only the sharing drawing initiator has drawing rights. However, in practice, the sharing of the drawing recipient may require drawing. Therefore, in order to guarantee the drawing requirement of the sharing drawing receiver, the embodiment of the invention can introduce a process of requesting sharing or exchanging the drawing right.
Optionally, the information transmission method of this embodiment may further include:
and receiving a Session Initiation Protocol (SIP) message sent by the second terminal.
The SIP message may include first request information, where the first request information is used to request the first terminal to transfer the drawing right to the second terminal. In this way, the handover of the drawing right between the first terminal and the second terminal can be achieved by means of SIP messages.
Or, the SIP message may include second request information, where the second request information is used to request the first terminal and the second terminal to share the drawing right. In this way, the drawing right can be shared between the first terminal and the second terminal by means of the SIP message.
Further, after receiving the SIP message sent by the second terminal, the method further includes:
sending an acceptance response message to the second terminal;
or sending a rejection response message to the second terminal.
For example, at the start time the first terminal UE1 has drawing right, the second terminal UE2 does not have drawing right, the subsequent UE2 has drawing requirement, the UE2 sends a SIP message requesting to hand over drawing right to the UE 1; if the UE1 accepts, then drawing right will be handed over by UE1 to UE2, and UE1 no longer has drawing right; if the UE1 rejects, the drawing right is not handed over, the UE1 still has drawing right, and the UE2 does not have drawing right.
For another example, the start time UE1 has drawing right, UE2 does not have drawing right, the subsequent UE2 has drawing requirement, and UE2 sends SIP message requesting to share drawing right to UE 1; if the UE1 accepts, the drawing right will be shared by the UE1 and the UE2, i.e., both the UE1 and the UE2 have the drawing right; if the UE1 rejects, the drawing right is not shared, the UE1 still has the drawing right, and the UE2 does not have the drawing right.
In this embodiment of the present invention, optionally, before step 101, the method may further include:
receiving a drawing background pattern selected by a first end user;
sending the drawing background pattern to a server;
receiving an auditing result sent by the server; the auditing result is obtained by auditing the drawing background pattern by the server; when an audit of the drawing background pattern passes, the audit result indicates that the drawing background pattern can be used; or, when the verification of the drawing background pattern is not passed, the verification result indicates that the drawing background pattern cannot be used;
determining whether the drawing background pattern can be used or not according to the auditing result;
transmitting the drawing background pattern to the second terminal when it is determined to use the drawing background pattern.
Wherein the painting background pattern cannot be used when it is determined that the painting background pattern cannot be used according to the audit result. When the drawing background pattern is transmitted to the server, it may be transmitted through the HTTP Post method.
The Server may be understood AS an auditing platform, such AS an Application Server (AS) of an IP Multimedia Subsystem (IMS), i.e. IMS/AS. The drawing background pattern can be selected as a locally stored image, a captured image (such as a map image including a current geographic position captured at a certain map APP interface or an image captured at a certain news APP interface), an image downloaded from a network platform, and the like. However, when an image with high security, such as a locally stored image, is used as a drawing background pattern, the image can be used without being checked.
Therefore, the drawing background pattern is checked by the server, so that the content of the drawing background pattern can be checked, and the background pattern can meet the basic requirements of related business supervision.
It should be noted that the application scenarios applicable to the embodiment of the present invention include, but are not limited to, the following:
scene one: remote drawing teaching;
scene two: information sharing; for example, both user 1 and user 2 are interested in news in today's top APP; when finding that the news alpha is interesting, the user 1 can initiate a shared drawing function in the process of voice communication with the user 2, intercept an interface containing the news alpha in today's top APP as a drawing background pattern, establish an RTP media stream for transmitting drawing image information between the user 1 and the user 2, send the drawing background pattern containing the news alpha content to the user 2, and further display the position of the news alpha content through drawing so as to be checked by the user 2;
scene three: information notification; for example, user 1 and user 2 have an appointment to eat together during a video call, the eating place is determined by user 2, but user 1 does not know; at this time, the user 2 may initiate a drawing sharing function, intercept a map image interface including the eating place in a certain map APP as a drawing background pattern, establish an RTP media stream for transmitting drawing image information between the user 1 and the user 2, send the drawing background pattern including the eating place to the user 1, and further draw to highlight the position of the eating place for the user 1 to view.

In the embodiment of the invention, the painting image information formed in the video call process is directly transmitted through the first RTP media stream which is independent relative to the second RTP media stream, and the second RTP media stream is the call RTP media stream and is used for transmitting the video call information, so that the transmission of the corresponding painting image information can be realized on the premise of not influencing the video call, and compared with the prior art of transmitting the painting image information by using an MSRP tunnel, the painting image information can avoid the generation of additional signaling overhead caused by frequently transmitting the MSRP information, thereby saving network resources.

In the specific embodiment of the present invention, the terminal a and the terminal B share the drawing, and the corresponding drawing sharing process mainly includes the following steps:
step 301: after a user selects a certain drawing background pattern locally, the terminal A uploads the drawing background pattern to the IMS/AS for auditing through an HTTP Post method.
Step 302: the IMS/AS checks the drawing background pattern and returns a checking result to the terminal A; if the verification is passed, the verification result indicates that the terminal A can use the drawing background pattern, otherwise, the verification result indicates that the terminal A cannot use the drawing background pattern.
Step 303: after the verification is passed, the terminal A carries out self-defined storage on the drawing background pattern for use when drawing sharing is initiated.
