Technical Field

Background

At present, video call functions between terminal devices are very common, different users can carry out video call at any time and any place, and communication efficiency between users is greatly improved. Video call interactive signaling generally has two modes, old version based on Http protocol signaling and new version based on webscolet protocol.

After the calling display device initiates a video call, it is possible that the protocol signaling of the calling and called display devices is both new and old. The WebSocket protocol reduces the delay time of signaling, improves the video call experience, and has a larger user base number in the signaling of the Http protocol. When the signaling server only supports Http protocol signaling, the video call requirement of the old version can be met, but the call with the WebSocket protocol-based display equipment cannot be realized, and the performance and experience cannot be improved; the signaling server based on the WebSocket protocol can meet the call requirement of a new version, reduce the signaling delay time and improve the user experience, but cannot be communicated with http protocol display equipment.

However, for some display devices that simultaneously support Http protocol and WebSocket protocol, when initiating a Http-based call, the display devices are connected to the Http signaling server, and when initiating a WebSocket-based call, the display devices are connected to the WebSocket signaling server, and for the uncertainty of the supported version of the called display device, the problem that the Http-based display device joins a call still cannot be solved.

Fig. 7 is a schematic diagram illustrating a plurality of display devices conducting a video call through a server according to an embodiment of the present application.

The display device server provided by the application comprises a general interface and a first controller. The universal interface receives a first video communication signaling sent by display equipment, wherein the first video communication signaling comprises a call request from the first display equipment or the second display equipment, the first video communication signaling is used for establishing communication connection between the first display equipment and the second display equipment, and the call request comprises a call request in a first protocol format and/or a call request in a second protocol format; the first controller coupled to the generic interface and configured to: and responding to the first video communication signaling, and generating a second video communication signaling for feeding back information in a signaling interaction process, wherein the second video communication signaling comprises a first protocol format access address and a second protocol format access address, and the second video communication signaling is used for enabling the receiving display equipment to establish video call connection according to the required protocol format access address. The following will explain the specific process of the display device and the server for realizing the compatibility of the video call with different protocol signaling.

In some embodiments, the Http signaling or the WebSocket signaling or both may be supported in the display device. The video call can be carried out among a plurality of display devices through a signaling server, wherein the signaling server can be implemented as a server provided by the application and is used for transmitting signaling required by the video call communication among the plurality of display devices, the signaling generally needs to be transmitted among different links of a communication network, such as a base station, a mobile control switching center and the like, each link carries out analysis processing and forms a series of operations and controls through interaction, and the function of the links is to ensure the effective and reliable transmission of information among the display devices.

Different types of protocol signaling, such as Http signaling and WebSocket signaling, cannot be directly communicated with each other, and real-time audio and video communication cannot be directly performed between the protocols and the signaling. If the display device D1 uses the Http signaling and the display device D2 uses the WebSocket signaling, real-time audio and video communication between the display device D1 and the display device D2 may not be performed.

Such signaling incompatibility often occurs, for example, http protocol signaling is used on a display device first, but with continuous service expansion and product upgrade, http protocol signaling cannot meet requirements, so developers develop WebSocket protocol signaling with more complete functions and better performance.

However, the Http protocol signaling is already used on a large number of display devices and software of all the display devices cannot be upgraded to the WebSocket protocol signaling in a short time, so that there is a period of time (even a long time because some display devices cannot be upgraded to the WebSocket protocol signaling for any reason), some display devices use the Http protocol signaling, some display devices use the WebSocket protocol signaling, and if it is ensured that each display device can perform real-time audio/video conversation with other display devices, compatible processing needs to be considered.

The audio and video processing signaling subjected to the compatibility processing can be compatible with an Http protocol signaling and a WebSocket protocol signaling at the same time. If the display device D1 upgrades the audio and video processing signaling, the display device D1 is provided with a display device D2 without upgrading software (only provided with an Http protocol signaling and communicating by using the Http protocol signaling) and an upgraded display device D3 (provided with the Http protocol signaling and a WebSocket protocol signaling and preferentially communicating by using the WebSocket protocol signaling), so that the communication between the software upgrading and the display device without software upgrading is ensured.

In some embodiments, the server may implement information transfer between multiple terminal devices through the websocket protocol. The method comprises the following steps that a first display device clicks an HTML5 application icon on a screen to trigger and establish websocket data connection with a built-in server; specifically, the establishing of the websocket data transmission channel between the first display device and the server includes: the method comprises the steps that a first display device sends a websocket handshake request to a built-in server; the first display equipment receives a handshake response returned by the server; the handshake response is a response of the server to a handshake request sent by the first display device.

The method comprises the steps that a first display device sends data information to at least one second display device; specifically, the first display device sends data information to at least one second display device through a websocket data transmission channel and a built-in server. Before the server sends the data information to the at least one second display device, the at least one second display device needs to establish websocket data connection with the built-in server. The push information comprises information resources of local equipment and a public network, and can be in various forms such as pictures, videos, tablets and the like.

And the first display equipment receives data information sent by other terminals. Specifically, the at least one second display device receives data information pushed by the server through a websocket data transmission channel, and browses in a mode of clicking HTML5 application.

The websocket data transmission channel established between the at least one second display device and the built-in server of the first display device is specifically as follows: the at least one second display device sends a websocket handshake request to the server; the at least one second display device receives a handshake response returned by the server; the handshake response is a response of the server to a handshake request sent by the at least second display device.

The at least one second display device sending data information to the other terminal includes: and the at least one second display device sends data information to the first display device through the websocket data transmission channel and the built-in server of the first television terminal. Before sending data information to the first display device through the server, the first display device needs to establish websocket data connection with the built-in server.

And the at least one second display device sends data information to the at least one other second display device which is connected with the server through the websocket data transmission channel and the built-in server of the first display device.

And the at least one second display device sends data information to the first display device and the at least one other second display device which is connected with the server through the websocket data transmission channel and the built-in server of the first display device.

Fig. 8 is a diagram illustrating a server-compatible signaling process according to an embodiment of the present application.

The first display device may be implemented as terminal a in the figure, which supports Http signaling; the second display device may be implemented as terminal B, which supports WebSocket signaling; the server may be implemented as a signaling server.

In some embodiments, the method for receiving a first video communication signaling sent by a display device includes: receiving a first protocol format call request sent by a first display device to a first protocol interface of the server; and/or receiving a second protocol format call request sent by the first display device to the second protocol interface of the server.

For example, the universal interface receives an Http signaling sent by a first display device or a WebSocket signaling sent by a second display device, and specifically includes: receiving an Http signaling sent by a first display device to the Http interface of the server; or receiving a Websocket signaling sent by the second display device to the server Websocket interface.

After the terminal A initiates a video call request, a first controller of the server creates a file session1 in a memory, and the file session1 is used for storing information customerA and customerB of video calls of the terminal A and the terminal B;

after receiving the request of the terminal A, the signaling server sends a push message containing a WebSocket connection address and an Http request address to a called terminal B, and meanwhile, the request return of the terminal A also obtains the address;

after obtaining the connection address, the terminal A and the terminal B can select the Http mode communication or the WebSocket mode communication according to the protocol signaling type supported by the terminals;

the method comprises the steps that a terminal A sends a first video communication signaling containing a Ring signal to a signaling server in the process of waiting for connection, and the signaling server sets the connection attribute of a customerA in a file session1 as Http;

after the terminal B establishes the WebSocket connection, the signaling server respectively establishes a Read Channel and a Write Channel for the connection, so as to realize the safe signaling receiving and sending function and also can be used for receiving and sending signals simultaneously;

after the terminal B sends a Ring Signal Signal to the signaling server, the signaling server sets the connection attribute of the customerB in the file session1 as WebSocket;

and the terminal A and the terminal B respectively send signaling to a signaling server through an Http interface and a WebSocket interface, and then convert the signaling to a Common interface (Common API) to perform Function processing (Function).

In some embodiments, the first controller, in response to the first video communication signaling, feeds back the second video communication signaling in the signaling interaction process, and specifically includes: responding to the first video communication signaling, and sending a second video communication signaling to the first display equipment in a first protocol communication mode; and/or sending the second video communication signaling to the second display device in a second protocol communication mode in response to the first video communication signaling containing the communication state of the first display device.

For example, the first controller sends the second video communication signaling to the first display device in an Http communication manner in response to the first video communication signaling, where the second video communication signaling is Http signaling; or responding to the first video communication signaling containing the communication state of the first display device, and sending the second video communication signaling to the second display device in a WebSocket communication mode, wherein the second video communication signaling is the WebSocket signaling.

For another example, the signaling server only needs to return response as the second video communication signaling for the Http request sent by the terminal a, that is, the first video communication signaling; however, for a video call in which a WebSocket protocol signaling terminal participates, the first controller needs to add broadcast communication.

In some embodiments, the first controller, in response to the first video communication signaling including the communication status of the first display device, sends the second video communication signaling to the second display device in a second protocol communication manner, specifically including: and the first controller responds to a first video communication signaling containing information of answering, hanging up or switching on and off the camera of the first display equipment and sends a second video communication signaling to the second display equipment in a second protocol communication mode.

For example, the first controller responds to a first video communication signaling containing information of answering or hanging up or switching on and off a camera of the first display device, and sends the second video communication signaling to the second display device in a WebSocket communication mode.

For another example, the first video communication signaling triggers the first controller of the signaling server to perform broadcast communication, which includes whether the current call has a change of state, such as an end user answering, hanging up, turning on or off a camera, and the like.

The first controller acquires information of terminals customerA and customerB participating in the video call from a file session1, wherein the connection attribute of the customerA is that Http does not need to broadcast, and the connection attribute of the customerB is that WebSocket needs to broadcast;

the first controller then writes second video communication signaling (body) generated based on the first video communication signaling containing the communication status, and/or the communication content transmitted by the display device into a write channel (write channel), and the signaling server sequentially transmits the second video communication signaling (body) to the terminal B in the order of the write channel. And sending a return result response corresponding to the WebSocket request by writing the return result response into the write channel.

The present application also provides a display device including a second controller configured to: sending a first video communication signaling containing a call request to a server, wherein the first video communication signaling is used for enabling the server to generate a second video communication signaling used for feeding back information in a signaling interaction process according to the first protocol format call request and/or a second protocol format call request contained in the call request; receiving a second video communication signaling which is sent by the server and contains a first protocol format access address and a second protocol format access address; and establishing communication connection with opposite-end display equipment according to the access address contained in the second video communication signaling.

For example, the display device sends a first video communication signaling containing a communication state and/or communication content to the server, the first video communication signaling sent by the display device to the server is used for enabling the server to generate a second video communication signaling used for feeding back information in a video call signaling interaction process according to the communication state and/or the communication content, and the second video communication signaling comprises the communication state and the communication content of the display device participating in the video call.

In some embodiments, second video communication signaling sent by the server and comprising the first protocol format access address and the second protocol format access address is received.

In some embodiments, the display device receives a second video communication signaling sent by the server, where when the first video communication signaling is an Http signaling, the second video communication signaling includes the Http signaling; or when the first video communication signaling is Websocket signaling, the second video communication signaling comprises Websocket signaling.

In some embodiments, the display device of the video call peer receives a second video communication signaling sent by the server, where when the first video communication signaling is an Http signaling, the second video communication signaling includes an Http protocol format access address and a WebSocket protocol format access address, and the display device of the peer participating in the video call selects a corresponding intervention address according to a protocol format supported by the display device to access the video call.

For example, after the first controller of the signaling server processes the WebSocket signaling sent to the terminal B, it is also required to check whether there are other WebSocket version terminals in the video call while updating the cache. Namely, if a terminal C performs a video call, the terminal C also supports a WebSocket protocol signaling terminal, and the first controller also needs to perform broadcast communication on the terminal C; if the terminal C supports Http protocol signaling, the second controller and the first controller of the server still obtain the latest call state by means of periodic request.

In some embodiments, the first display device may be implemented as terminal a in the figure, which supports Http signaling; the second display device may be implemented as a terminal B, which supports WebSocket signaling; the server may be implemented as a signaling server.

A terminal A initiates a video call, a signaling server receives a request of the terminal A and then sends a push message containing a WebSocket connection address and an http request address to a called terminal B, and the request of the terminal A returns to obtain the address; after the terminal A and the terminal B obtain the connection addresses, the http communication mode or the WebSocket communication mode can be selected for video call according to the self-supporting type.

The terminal A periodically sends an http request containing a Ring signal, namely a first video communication signaling, for example, at a frequency of 1 time per second for ringing, and waits for the terminal B to answer; the terminal B supports WebSocket protocol signaling and needs to establish WebSocket connection, and the connection is long connection and can realize full duplex communication.

After the terminal B establishes connection, sending a second video communication signaling containing Ring Signal signals to a signaling server, and binding and caching the signaling server, the terminal B and the connection; when the communication state of the terminal B is not changed, the signaling does not need to be periodically sent to the server, and the signaling interaction is not needed.

When receiving the call, the terminal B sends a first video communication signaling containing a Receive Signal to a signaling server; a calling terminal A acquires the communication state of a terminal B through a first video communication signaling feedback signaling, namely a second video communication signaling, which periodically contains a Ring signal; after the terminal a successfully receives the call, the terminal a periodically sends, for example, 1 time per second, an http request including Talking information, that is, a first video communication signaling, to the signaling server to maintain a call state, and acquires latest information, where the latest information includes a communication state and communication content of the display device participating in the video call.

When the terminal B closes the camera, sending a first video communication signaling containing a Signal for closing the camera to the signaling server, and the terminal A obtaining the communication state of the terminal B closing the camera through a feedback second video communication signaling of the first video communication signaling containing a periodical Signal.

When the camera is closed by the terminal A, a request containing a Talking signal, namely a first video communication signaling is sent to the signaling server, the signaling server obtains a WebSocket connection address of the terminal B through the cache, and the request of the terminal A is broadcasted, so that the terminal B receives the current communication state of the terminal A through a second video communication signaling.

The terminal A sends a request containing a Bye signal, namely a first video communication signaling to the signaling server to end the current call, and the signaling server also acquires the connection of the terminal B and synchronizes the call state of the current terminal A through broadcast communication.

In some embodiments, the display device displays call information of all users in the multi-party call in response to initiation or joining of the multi-party call, the call information of different users corresponding to different display areas in the multi-party call display interface.

The display device responds to the initiation of the multi-party call, namely, the display device responds to a call invitation which is triggered by a user and faces at least one other user, and the multi-party call between the user and the other user is formed. Illustratively, the user 1 sends a call invitation to the user 2 and the user 3 respectively by triggering the display device running in the smart device 1 to form a multi-party call between the users 1-3. It should be noted that the multiparty call between different users is realized through the communication connection between the display device where the user is located and the server.

It should be noted that the call invitation triggered by the user is not limited to the initial initiation of the multi-party call, but may also be an extension to the user already participating in the multi-party call. For example, in the multi-party call formed above, each user may also continue to initiate a call invitation to another user (for example, users 4 and 5), so that users 4 and 5 are newly added to the multi-party call.

The display device responding to the joining of the multi-party call means that the display device responds to the call joining triggered by the user after receiving the call invitation initiated by other display devices to join the multi-party call between the user and the user of the other display devices. That is, the initiation of the multi-party call responded by the display device corresponds to the call invitation actively initiated by the display device, and the joining of the multi-party call responded corresponds to the answering of the call invitation initiated by other users.

Therefore, for different display devices, by responding to the initiation or joining of the multi-party call, the multi-party call between different users corresponding to the display devices is formed.

The call information of all users in the multi-party call corresponds to the call state of the user in the multi-party call, and when the call information corresponding to the user is displayed in the multi-party call display interface, the user is shown as one of the members in the multi-party call. It should be noted that the multi-party call display interface refers to an interface display of the display device for the multi-party call.

The call information corresponding to the user may also be different corresponding to different multi-party call modes. Illustratively, in a multi-party voice call, call information corresponding to a user is a head portrait of the user;

in some embodiments, when a call termination action triggered in the display area is monitored, a call termination request facing a user corresponding to the display area is sent to the server.

The call termination action is a trigger action set by the display device for executing call termination of the user corresponding to the display area, for example, the call termination action may be double-clicking, long-pressing, or dragging the display area, and is not limited here. Therefore, when the display device monitors the call termination action triggered in the display area, the target user needing to execute call termination can be acquired.

As mentioned above, the server is a hub for implementing multi-party call, and multi-party calls between different display devices need to depend on multi-party call connections established by the server. In the multi-party call connection established by the server, each display device establishes call connection with the server respectively, and call acquisition of each user in the multi-party call is realized by the display device through transfer transmission of the call flow by the server.

Therefore, after monitoring the call termination action triggered in the display area, the display device needs to send a call termination request to the server for a target user who needs to perform call termination, so as to request the server to kick the target user out of the multi-party call.

In some embodiments, the server responds to the call termination request according to the call authority of the display device itself and the call states of other display devices.

The communication authority of the display device corresponds to the communication authority of the user where the display device is located. As mentioned above, the call permission of the user of the display device at least includes at least one of a call invitation permission, a call joining permission, and a call termination permission, where the call termination permission refers to a permission that the user of the display device can control to terminate the call connection of some or all users in the multi-party call.

The call state of the other display device means whether the user of the other display device answers the multi-party call invitation. For the server, in the established multi-party call connection, each display device needs to periodically return call state information to the server according to a preset protocol, so that the server can master the call state of the display device in real time. Illustratively, the server is a signaling server, the display device is in a Ring state when not answering the multi-party call invitation, and periodically returns a signaling message "Meeting Ring" to the server; the display device is in an answering state when the multiparty call invitation is answered, and periodically returns a signaling message 'Meeting Talking' to the server.
