Technical Field

[0002] With the continuous upgrade of video codec chips in TV set-top boxes, they now support video encoding and playback at 1080p and even 4096p resolutions. Based on the performance of existing set-top boxes, ultra-high-definition audio and video calls between TVs have been realized. However, when making video calls between TVs, the existing IP Multimedia Subsystem (IMS) core network mostly supports high-definition resolution (630×480) used by mobile phones. The bandwidth capacity and networking methods of the current IMS network do not support the forwarding of ultra-high-definition video at resolutions of 1080p and above.

[0034] It should be understood that the specific embodiments described herein are only used to explain the present application and are not intended to limit the present application.

[0035] The embodiment of the present application provides a call acceleration method, which is applied to a call acceleration device. Figure 1 A flow chart of a call acceleration method provided in an embodiment of the present application is shown as follows: Figure 1 As shown, the call acceleration method may include:

[0036] S101: Transmit communication signaling between a first terminal and a second terminal through a first network to establish a call between the first terminal and the second terminal.

[0037] In an embodiment of the present application, the call acceleration device transmits communication signaling between the first terminal and the second terminal through the first network and establishes a call between the first terminal and the second terminal.

[0038] It should be noted that the first terminal and the second terminal can be a first TV terminal and a second TV terminal. Therefore, this application is applicable to the scenario where users use TV terminals to make video calls with each other.

[0039] It should be noted that the first network may be an IP Multimedia Subsystem (IMS) core network.

[0040] In the embodiment of the present application, the communication signaling includes a call request signaling and an answer response signaling. Therefore, the first terminal and the second terminal establish a call through the call request signaling and the answer response signaling.

[0041] Specifically, the call acceleration device transmits a call request signaling sent by the first terminal to the second terminal through the first network; when the first terminal receives a call response signaling returned by the second terminal through the first network, a call is established between the first terminal and the second terminal.

[0042] It should be noted that when establishing a call between the first terminal and the second terminal, both the first terminal and the second terminal need to access the communication capability platform, that is, the first terminal accesses the first communication capability platform and the second terminal accesses the second communication capability platform.

[0043] It should be noted that the communication capability platform can be divided according to provinces, and each province has its own corresponding communication capability platform. The specific division rules are determined according to actual conditions, and the embodiments of this application do not limit this.

[0044] In the embodiment of the present application, when the first terminal accesses the first communication capability platform and the second terminal accesses the second communication capability platform, the embodiment of the present application provides specific steps for establishing a call based on the call request signaling and the answer response signaling. Figure 2As shown, Figure 2 An exemplary call establishment process flow chart provided in an embodiment of the present application includes the following specific steps:

[0045] S201. A first communication capability platform sends a call request signaling to a second communication capability platform via a first network through a first signaling service process.

[0046] In an embodiment of the present application, when a first terminal initiates a call request signaling to a second terminal, the first communication capability platform accessed by the first terminal sends the call request signaling to the second communication capability platform through the first network via the first signaling service process.

[0047] It should be noted that the call request signaling initiated by the first terminal to the second terminal is initiated through the Session Initiation Protocol SIP.

[0048] For example, Figure 3 An exemplary call acceleration process diagram provided in an embodiment of the present application is as follows: Figure 3 As shown, the first terminal initiates a call request signaling to the second TV terminal through the SIP protocol. Then, the first signaling service process of the first communication capability platform accessed by the first terminal forwards the call request signaling to the IMS core network. After receiving the call request signaling, the IMS core network searches for the second communication capability platform corresponding to the called number according to the called number in the call request signaling, and finally, sends the call request signaling to the second communication capability platform.

[0049] S202: The second communication capability platform searches for the terminal identifier corresponding to the call request signaling through the second signaling service process, and sends the call request signaling to the second terminal corresponding to the terminal identifier.

[0050] In an embodiment of the present application, after the second communication capability platform receives the call request signaling, the second communication capability platform searches for the terminal identifier corresponding to the call request signaling through the second signaling service process, and sends the call request signaling to the second terminal corresponding to the terminal identifier.

[0051] Exemplarily, after receiving the call request signaling, the second communication capability platform parses the call request signaling through the second signaling service process to obtain the called number, then searches for the corresponding second terminal based on the called number and sends the call request signaling to the second terminal.

[0052] It should be noted that after the second terminal receives the call request signaling, a ringing interface appears on the display interface of the second terminal.

[0053] S203: After the second terminal responds to the call request signaling, the second terminal returns the answer response signaling to the second signaling service process of the second communication capability platform.

[0054] In the embodiment of the present application, after the second terminal responds to the call request signaling, the call acceleration device returns the answer response signaling to the second signaling service process of the second communication capability platform.

[0055] Exemplarily, after the second terminal receives the call request signaling, it returns the answer response signaling to the second signaling service process of the second communication capability platform where the second terminal is located.

[0056] S204. After receiving the answer response signaling, the second signaling service process sends the answer response signaling to the first network, and the first network sends the answer response signaling to the first signaling service process.

[0057] In an embodiment of the present application, after the second signaling service process receives the answer response signaling, the second signaling service process sends the answer response signaling to the first network, and the first network sends the answer response signaling to the first signaling service process.

[0058] Exemplarily, after the second signaling service process receives the answer response signaling, the second signaling service process sends the answer response signaling to the IMS core network, and then the IMS core network forwards the answer response signaling to the first signaling service process.

[0059] S205. After the first signaling service process receives the answer response signaling, the answer response signaling is sent to the first terminal. When the first terminal receives the answer response signaling, a call between the first terminal and the second terminal is established.

[0060] In an embodiment of the present application, after the first signaling service process receives the answer response signaling, the answer response signaling is sent to the first terminal. When the first terminal receives the answer response signaling, a call is established between the first terminal and the second terminal.

[0061] It should be noted that when the first terminal receives the answer response operation sent by the second terminal, the screen interface of the first terminal will display that the call signaling is successfully established, and the first terminal and the second terminal can then communicate.

[0062] S102: Acquire the media streams to be transmitted between the first terminal and the second terminal during the call, and transmit the media streams to be transmitted through the second network.

[0063] In an embodiment of the present application, when a call is conducted between a first terminal and a second terminal, the call acceleration device obtains the media stream to be transmitted between the first terminal and the second terminal during the call, and transmits the media stream to be transmitted through the second network.

[0064] It should be noted that the second network is an Over The Top (OTT) acceleration network.

[0065] In the embodiment of the present application, when the media stream to be transmitted is transmitted, it is transmitted between the first communication capability platform and the second communication capability platform through the second network.

[0066] It should be noted that before transmitting the media stream to be transmitted, it is necessary to establish a first media channel for the first media forwarding process between the first terminal and the first communication capability platform; it is necessary to establish a second media channel for the second media forwarding process between the second terminal and the second communication capability platform.

[0067] It should be noted that both the first media channel and the second media channel are ultra-high-definition media channels, and an ultra-high-definition video call between the first terminal and the second terminal can be implemented through the ultra-high-definition media channels.

[0068] It should be noted that the first communication capability platform includes a first media forwarding process, and the second communication capability platform includes a second media forwarding process.

[0069] In the embodiment of the present application, when the media stream to be transmitted is transmitted, it is transmitted between the first media forwarding process and the second media forwarding process through the second network.

[0070] For example, assuming that the first terminal needs to transmit the media stream to be transmitted to the second terminal, the first terminal needs to send the media stream to be transmitted to the first media forwarding process of the first communication capability platform through the first media channel, and then the first media forwarding process sends the media stream to be transmitted to the second media forwarding process through the OTT acceleration network. Finally, the second media forwarding process sends the media stream to be transmitted to the second terminal through the second media channel, thereby realizing data transmission between the first terminal and the second terminal.

[0071] For example, assuming that the second terminal needs to transmit the media stream to be transmitted to the first terminal, the second terminal needs to send the media stream to be transmitted to the second media forwarding process of the second communication capability platform through the second media channel, and then, the second media forwarding process sends the media stream to be transmitted to the first media forwarding process through the OTT acceleration network. Finally, the first media forwarding process sends the media stream to be transmitted to the first terminal through the first media channel, thereby realizing data transmission between the first terminal and the second terminal.

[0072] In an embodiment of the present application, during the process of transmitting the media stream to be transmitted between the first terminal and the second terminal, a preset call holding packet is sent to the first network through the first communication capability platform and the second communication capability platform to maintain the call between the first terminal and the second terminal.

[0073] It should be noted that, during the process of transmitting the media stream to be transmitted between the first terminal and the second terminal, a third media channel needs to be established between the first media forwarding process and the first network; a fourth media channel needs to be established between the second media forwarding process and the first network.

[0074] Exemplarily, during the process of transmitting the media stream to be transmitted, the first media forwarding process sends a preset call holding packet to the first network through the third media channel, and the second media forwarding process sends a preset call holding packet to the first network through the fourth media channel.

[0075] It should be noted that when using the third media channel and the fourth media channel to send call holding media packets to the IMS core network, they can be sent periodically. Every preset time period, the call holding media packets are sent to the IMS core network through the third media channel and the fourth media channel to maintain the call between the first terminal and the second terminal, so that the first terminal and the second terminal will not experience any lag in the high-definition video call. The preset time period can be 1 minute or 10 minutes. The specific preset time period is determined according to the actual situation and is not limited in the embodiment of the present application.

[0076] It should be noted that after the call between the first terminal and the second terminal ends, the sending of the call holding media packet is stopped.

[0077] The embodiment of the present application provides a call acceleration method and storage medium, and the call acceleration method includes: transmitting communication signaling between a first terminal and a second terminal through a first network, establishing a call between the first terminal and the second terminal; obtaining the media stream to be transmitted between the first terminal and the second terminal during the call, and transmitting the media stream to be transmitted through a second network. With the above implementation scheme, since the present application implements the two steps of establishing a call and transmitting a media stream respectively by two networks instead of using the same network to implement two functions, the network load is reduced, and the problem of video call freezes due to excessive network load when establishing a call and transmitting a media stream through the same network is solved, and the stability of users using terminals for video calls is improved.
