DETAILED DESCRIPTION

The following will be combined with the drawings in the present disclosure to clearly and completely describe the technical solutions in the present disclosure. Obviously, the described embodiments are only part of the embodiments of the present disclosure, not all of the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present disclosure.

It should be noted that, in the present disclosure, words such as "exemplarily" or "for example" are used to indicate examples, illustrations or explanations. Any embodiment or design described as "exemplarily" or "for example" in the present disclosure should not be interpreted as being more preferred or more advantageous than other embodiments or designs. Specifically, the use of words such as "exemplarily" or "for example" is intended to present related concepts in some way.

In the following, the terms "first", "second", etc. are used for descriptive purposes only and are not to be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, a feature defined as "first", "second", etc. may explicitly or implicitly include one or more of the features.

In the description of the present disclosure, unless otherwise specified, "/" means "or", for example, A/B can mean A or B. "And/or" in this article is only a way to describe the association relationship of associated objects, indicating that there can be three relationships, for example, A and/or B can mean: only A, only B, and A and B. In addition, "at least one" means one or more, and "a plurality" means two or more.

With the continuous development of mobile communication technology, video ringback tone has become a common function to improve user experience; however, since most calls will be connected within 20 seconds during the call process, the average time for users to watch video ringback tone is short (specifically only 15 seconds); therefore, the user experience of watching video ringback tone is reduced.

The disclosed embodiment provides a method, device and storage medium for playing video ringback tone; the method is applied to the scenario of mobile communication (i.e., the calling device calls the called device through a phone number or social software). In this scenario, the calling device sends a call request to the called device and plays the video ringback tone; the called device picks up the phone after receiving the call request and sends an off-hook message to the calling device; after receiving the off-hook message, the calling device stops playing the video ringback tone and establishes a call connection with the called device. Then, the ringback tone platform obtains capability information for indicating the state of the camera of the called device; when the capability information indicates that the camera of the called device is in the off state, the ringback tone platform negotiates audio and video media with the calling device; and after the audio and video media negotiation is successful, the ringback tone platform sends the video ringback tone to the calling device; so that the calling device plays the video ringback tone during the call with the called device; thereby increasing the time for the user to watch the video ringback tone, and then improving the user's experience of watching the video ringback tone.

Next, the process of calling, answering and playing a ring back tone between a calling device 101 and a called device 103 will be described in conjunction with the schematic diagram of the architecture of the mobile communication system shown in FIG1. The communication system shown in FIG1 includes: a calling device 101, a ring back tone platform 102 and a called device 103; the calling device 101 is connected to the called device 103 via the ring back tone platform 102.

It should be understood that, in general, the various devices in the above system are connected wirelessly. In order to facilitate observation of the connection relationship between the various devices, they are marked with solid lines in FIG. 1 .

The process of calling, answering and playing the ringback tone between the calling device and the called device is shown in FIG2, and includes:

S110 , the calling device 101 sends a conversation (call) request to the called device 103 through the color ring back tone platform 102 .

The call request includes identification information of the called device 103 , such as the telephone number of the called device 103 .

An example implementation of S110 includes: the calling device 101 sends a call request to the CRBT platform 102 ; then, the CRBT platform 102 determines the called device 103 according to the identification information of the called device 103 in the call request, and forwards the call request to the called device 103 .

S120 : The calling device 101 obtains a video ringback tone from the ringback tone platform 102 .

It should be noted that the above-mentioned video ringback tone is a video ringback tone selected (ie, set or subscribed) by the called device 103 in the ringback tone platform 102 , that is, the ringback tone platform 102 contains a video ringback tone corresponding to the called device 103 .

An example implementation of S120 includes: the CRBT platform 102 determines that the called device 103 is configured with a video CRBT according to the identifier of the called device 103 in the off-hook message, and then the CRBT platform 102 sends the video CRBT configured by the called device 103 to the calling device 101 .

S130: The calling device 101 plays a video ringback tone.

S140 : The called device 103 sends an off-hook message to the calling device 101 through the color ring back tone platform 102 .

The off-hook message is a response message of the called device 103 to the call request of the calling device 101; for example, the off-hook message is a response message of the call request sent by the called device 103 to the calling device 101 after the called device 103 answers the call represented by the call request.

It should be noted that after the CRBT platform 102 receives the off-hook message sent by the called device 103 to the calling device 101, the CRBT platform 102 stops sending the video CRBT to the calling device.

S150: After receiving the off-hook message, the calling device 101 stops playing the video ringback tone.

S160: The calling device 101 establishes a call connection with the called device 103.

Exemplarily, the calling device 101 and the called device 103 may be electronic devices such as mobile phones, tablet computers, laptop computers, netbooks or desktop computers.

It should be noted that the calling device 101 and the called device 103 may be electronic devices with the same hardware structure or electronic devices with different hardware structures. The embodiment of the present disclosure is described by taking the calling device 101 and the called device 103 as electronic devices with the same hardware structure as an example, and will not be repeated later.

Exemplarily, the above-mentioned ring back tone platform 102 can be an application on a tablet computer, a laptop computer, a server, a desktop computer or an electronic device.

The embodiment of the present disclosure provides a method for playing a video ringback tone, which is applied in a scenario where a calling device and a called device are talking, and the method can be applied to the communication system shown in the above FIG1. In combination with the above process of calling, answering and playing a ringback tone between the calling device and the called device, the present disclosure also provides a method that continues to be executed after the above S160, so that the calling device can still play the video ringback tone after the called device picks up the phone.

The method for playing video ringback tone provided by the present disclosure includes S210-S240 as shown in FIG3 .

S210. The color ring back tone platform obtains capability information of the called device.

The above capability information is used to indicate the state of the camera of the called device; the state of the camera includes: on state and off state; wherein, when the state of the camera is off state, the called device does not support sending the video captured by the camera of the called device to the calling device stream (ie, video data); when the camera is in the on state, the called device supports sending the video stream captured by the camera of the called device to the calling device.

In one embodiment, when the called device detects that the camera of the called device is in the off state, the called device sends an update message (such as an update message, hereinafter referred to as the first media update message) to the ringback tone platform, so that the ringback tone platform can obtain the capability information of the called device from the first media update message. For example, the first media update message includes: the status information of the video transceiver capability, or the video transceiver port information; wherein the status information of the video transceiver capability and the video transceiver port information are both used to indicate the status of the camera of the called device. At this time, the above capability information can be the status information of the video transceiver capability, or the video transceiver port information in the above first media update message.

Exemplarily, it is assumed that the above-mentioned first media update message includes: status information of video transceiving capability; at this time, the message body of the first media update message is as shown in the following code block 1, and the status of the video transceiving capability in the code block is a receiving-only state (ie: a=recvonly); that is, the called device only receives the video stream captured by the camera of the calling device and sent by the calling device, but does not send the video stream captured by the camera of the called device to the calling device; that is, the status of the camera of the called device is off at this time.

Code Block 1

Direction = UE_TO_NETWORK/* is used to indicate that the message is sent by the called device to the color ring back tone platform. */

m＝audio 32674 RTP/AVP 99 101/*Used to indicate that the audio port number of the called device is 32674, the audio transmission protocol is the real-time transport protocol (RTP) or the audio video profile (AVP); the protocol type is 99 and 101. */

a＝sendrecv/*Used to indicate that the state of audio receiving and sending capability is both receiving and sending state. */

m＝video 25150 RTP/AVP 124 12/*Used to indicate that the video port number of the called device is 25150, the video transmission protocol is RTP or AVP, and the protocol type is 124 and 12. */

a=recvonly/*Used to indicate that the state of the video transceiver capability is only receiving state, that is, only receiving video, not sending local video. */

As another example, assume that the first media update message includes: video sending and receiving port information; based on the code block 1, when the video port number of the called device is 0 (ie: m = video 0 RTP/AVP 124 12), at this time, the called device has no port for sending and receiving video data, that is, the state of the video sending and receiving capability of the called device is a non-sending state, that is, the camera of the called device is in an off state at this time.

In another embodiment, the above-mentioned color ring back tone platform determines the capability information of the called device according to the off-hook message in the above-mentioned S140. It should be noted that, in the embodiment of the present disclosure, the off-hook message sent by the called device is used to instruct the calling device to establish an audio call (such as a voice call) or a one-way video call with the called device, wherein the one-way video call is a call in which the called device only receives the video stream sent by the calling device, and does not send the video stream captured by the camera of the called device to the calling device.

It should be understood that, no matter whether the calling device and the called device are in an audio call or a one-way video call, the called device does not need to send the video stream captured by the camera of the called device to the calling device; therefore, when the off-hook message indicates that the calling device and the called device establish an audio call or a one-way video call, the color ringback tone platform can determine the capability information of the above-mentioned called device based on the audio call or one-way video call indicated by the off-hook message.

For example, assume that the calling device initiates a video call request to the called device. After the called device receives the video call request, the user of the called device can choose a voice call. At this time, the called device sends an off-hook message to the calling device through the color ringback tone platform. The off-hook message is used to instruct the calling device to establish a voice call (i.e., an audio call) with the called device.

In another example, suppose that the calling device initiates a video call request to the called device. After the called device receives the video call request, the user of the called device can choose a one-way video call. At this time, the called device sends an off-hook message to the calling device through the color ring back tone platform. The off-hook message is used to instruct the calling device to establish a one-way video call with the called device. After the call is successfully established, user A using the calling device cannot see the user A using the called device. The video screen of user B who called the device; however, user B can see the video screen of user A.

For example, in this embodiment, the off-hook message in the above S140 may include indication information for indicating the type of call to be established between the calling device and the called device (eg, an audio call or a one-way video call).

It should be noted that, when the CRBT platform receives the above capability information, and the capability information indicates that the camera of the called device is in an off state, the CRBT platform may be triggered to execute the following S220.

S220: The ring back tone platform negotiates audio and video media with the calling device.

Through the audio and video media negotiation, the color ring back tone platform can determine the content of the video color ring back tone sent to the calling device, such as the video part of the video color ring back tone and/or the audio part of the video color ring back tone.

In combination with FIG. 3 , as shown in FIG. 4 , the example implementation of the above S220 includes: S221 - S222 .

S221. The color ring back tone platform sends an audio and video stream negotiation message to the calling device.

The above audio and video stream negotiation message includes: the status of the video transceiving capability and the audio transceiving capability of the color ring back tone platform; that is, the above S221 is that the color ring back tone platform sends its own audio and video stream transceiving capability to the calling device.

Exemplarily, the audio and video stream negotiation message (such as an update message) has a message body as shown in the following code block 2. The P-Early-Media in the code block is an attribute used to indicate whether the ringback tone platform supports sending video ringback tone to the calling device during a call (i.e., a call between the calling device and the called device); when the attribute value of the P-Early-Media attribute is sendrecv, it indicates that the ringback tone platform supports sending video ringback tone to the calling device during a call. In this code block, "m＝audio 32674 RTP/AVP 99 98 8 0 109 112 110 100 101 111 113 18 a＝sendrecv" is used to indicate that the audio transceiver capability of the ringback tone platform is in the transceiver state; m＝video 25150 RTP/AVP 123 125 124 122 a＝sendrecv is used to indicate that the video transceiver capability of the ringback tone platform is in the transceiver state.

Code Block 2

Direction = NETWORK_TO_UE/*Used to indicate that the update is a message sent by the color ring back tone platform to the calling device. */

P-Early-Media:sendrecv/*Used to indicate that the CRBT platform supports sending video CRBT to the calling device during a call. */

m＝audio 32674 RTP/AVP 99 98 8 0 109 112 110 100 101 111 113 18

a＝sendrecv

m＝video 25150 RTP/AVP 123 125 124 122

a＝sendrecv

S222: The calling device sends a response message of the audio and video stream negotiation message to the color ring back tone platform.

It should be noted that the above S221 is the CRBT platform sending its own audio and video stream receiving and sending capabilities to the calling device; at this time, the above response message is used to instruct the calling device to select the capability information from the audio and video stream receiving and sending capabilities of the CRBT platform.

The status information of the audio transceiver capability or the audio transceiver port information in the above-mentioned response message is used to indicate that the calling device does not receive the audio data sent by the color ring back tone platform; the status information of the video transceiver capability or the video transceiver port information in the response message is used to indicate that the calling device receives the video data sent by the color ring back tone platform; that is: in the scenario where the color ring back tone platform sends a video color ring back tone to the calling device, the status information of the audio transceiver capability or the audio transceiver port information in the above-mentioned response message is used to indicate that the calling device does not play the audio part of the video color ring back tone; the status information of the video transceiver capability or the video transceiver port information in the response message is used to indicate that the calling device plays the video part of the video color ring back tone.

For example, assuming that the response message is as shown in the following code block 3, audio 0 in the code block is used to indicate that the port number for the calling device to send and receive audio data is 0, and the calling device has no port for sending and receiving audio data. At this time, the calling device does not receive the audio data sent by the color ring back tone platform; that is, when the color ring back tone platform subsequently sends a video color ring back tone to the calling device, the calling device does not receive the audio part of the video color ring back tone sent by the color ring back tone platform. m＝video 25150 a＝sendrecv is used to indicate that the video sending and receiving capability status of the calling device is in a sendable state, that is, when the color ring back tone platform subsequently sends a video color ring back tone to the calling device, the calling device receives the video part of the video color ring back tone sent by the color ring back tone platform.

Code Block 3

Direction = UE_TO_NETWORK

m＝audio 0 RTP/AVP 99 101/*Used to instruct the calling device not to receive the audio data sent by the ringback tone platform. */

a＝sendrecv

m＝video 25150 RTP/AVP 124 12

a＝sendrecv

As another example, assume that the above-mentioned response message is as shown in the following code block 4, and the audio receiving and sending capability status in the code block is the removal status inactive (i.e., non-receiving and sending status); at this time, when the color ringback tone platform subsequently sends a video color ringback tone to the calling device, the calling device does not receive the audio part of the video color ringback tone sent by the color ringback tone platform.

Code Block 4

Direction = UE_TO_NETWORK

m＝audio 32674 RTP/AVP 99 101

a＝inactive/*Used to indicate that the state of audio transceiver capability is removed (i.e., not transceiver)*/

m＝video 25150 RTP/AVP 124 12

a＝sendrecv

It should be noted that, after receiving the above response message, the above CRBT platform indicates that the audio and video media negotiation is successful, and the CRBT platform executes the following S230.

S230: The ring back tone platform sends a video ring back tone to the calling device.

It should be noted that, since the status information of the audio transceiver capability or the audio transceiver port information in the response message in the above S222 indicates that the calling device does not receive the audio data sent by the color ring back tone platform, and the status information of the video transceiver capability or the video transceiver port information in the response message indicates that the calling device receives the video data sent by the color ring back tone platform; therefore, the video color ring back tone sent by the above color ring back tone platform to the calling device only includes the video part of the video color ring back tone, and does not include the audio part of the video color ring back tone.

S240: The calling device plays a video ringback tone.

It should be understood that, since the above S240 is executed after the above S160, the above video ringback tone is played during the call between the calling device and the called device.

For example, as shown in FIG. 5 , the calling device and the called device are making a video call. Since the camera of the called device is turned off, the called device plays the video picture sent by the calling device (referred to as the calling end video picture); and the calling device plays the video ringback tone picture.

In the embodiment of the present disclosure, during a call between a calling device and a called device, capability information indicating the state of a camera of the called device is obtained through a color ring back tone platform; when the capability information indicates that the camera of the called device is in an off state, the color ring back tone platform negotiates video media with the calling device; and after the audio and video media negotiation is successful, sends a video color ring back tone to the calling device; so that the calling device plays the video color ring back tone during a call with the called device; thereby increasing the time for users to watch the video color ring back tone, and further improving the user's experience of watching the video color ring back tone.

In some embodiments, when a voice call is established between a calling device and a called device, the above-mentioned method for playing a video ringback tone further includes: the ringback tone platform negotiates audio and video media with the called device, and after the audio and video media negotiation is successful, the ringback tone platform sends the video ringback tone selected (i.e., set or subscribed) by the calling device on the ringback tone platform to the called device; so that the called device plays the video ringback tone during the call with the calling device; as shown in FIG6 , when the calling device plays the screen of video ringback tone A, the called device plays the screen of video ringback tone B.

The above method performs audio and video media negotiation with the called device through the color ring back tone platform. After the audio and video media negotiation is successful, the color ring back tone platform sends a The calling device sends a video ringback tone; so that the called device plays the video ringback tone during the call with the calling device, so that the called user (i.e., the user using the called device) can watch the video ringback tone during the call between the calling device and the called device, further improving the user's experience of watching the video ringback tone.

It should be noted that, in both the methods for playing video ringback rings shown in FIG. 3 and FIG. 4 , the calling device passively receives and plays the video ringback rings; thus, the flexibility of the methods for playing video ringback rings is relatively low.

The embodiment of the present disclosure provides another method for playing a video ringback tone, which is applied in a scenario where a calling device and a called device are talking, and the method can be applied to the communication system shown in the above FIG1. In combination with the above process of calling, answering and playing a ringback tone between the calling device and the called device, the present disclosure further provides a method that is continued to be executed after the above S160, so that the calling device actively receives and plays a video ringback tone.

The method for playing video ringback tone provided by the present disclosure includes S310-S360 as shown in FIG. 7 .

S310: The calling device sends target indication information to the color ring back tone platform.

The target indication information is used to instruct the calling device to play the video ringback tone during the call with the called device. That is, at this time, the calling device informs the ringback tone platform that the calling device does not receive the video data sent by the called device during the call with the called device.

It should be noted that the above S310 can be executed by the calling device during a video call (ie, a two-way video call) with the called device; or it can be executed after the calling device receives an off-hook message forwarded by the color ring back tone platform.

S320: The color ring back tone platform forwards the target indication information to the called device.

The target indication information is used to trigger the called device to send the capability information in S210 to the color ring back tone platform.

It should be noted that, in the case where the camera of the called device is in an on state, the target indication information is also used to instruct the called device to set the state of the camera to an off state.

For example, as shown in FIG8 , the calling device and the called device are making a video call. At this time, the calling device plays the video screen of the called end, and the called device plays the video screen of the calling end. At this time, when the user of the calling device clicks the button to play the ringback tone, the calling device forwards the target indication information for instructing the calling device to play the video ringback tone during the call with the called device to the called device through the ringback tone platform. After the called device receives the target information, as shown in FIG9 , the called device turns off the camera.

S330: The color ring back tone platform obtains capability information of the called device.

It should be noted that the above-mentioned capability information is consistent with the capability information in the above-mentioned S210. For the example description of the above-mentioned capability information, please refer to the above-mentioned relevant description of S210; the implementation method of the above-mentioned S330 is consistent with the implementation method of the first embodiment in S210.

S340: The ring back tone platform negotiates audio and video media with the calling device.

S350: The color ring back tone platform sends a video color ring back tone to the calling device.

S360: The calling device plays the video ringback tone.

It should be noted that the implementation method of the above S340-S360 is consistent with the implementation method of S220-S240. For the example implementation method of S340-S360, please refer to the relevant description of S220-S240 above, which will not be repeated here.

In the embodiment of the present disclosure, the calling device sends target indication information to the called device through the color ring back tone platform, which is used to instruct the calling device to play a video color ring back tone during a call with the called device; so that the called device sets the camera status on it to the off state, and then the calling device receives and plays the video color ring back tone sent by the color ring back tone platform during a call with the called device, thereby improving the flexibility of the method for playing video color ring back tone.

In some embodiments, the method for playing the video ringback tone described in S310-S360 above may also be triggered by the called device, as shown in the following example:

As shown in FIG8 , the calling device and the called device are making a video call.
