[0028] To enable those skilled in the art to better understand the technical solutions in the embodiments of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art should fall within the protection scope of the present invention.

[0029] The specific implementation of the embodiments of the present invention will be further described below with reference to the accompanying drawings.

[0030] Figure 1 This is a schematic flowchart illustrating a communication method according to an embodiment of the present invention. Figure 1 The communication method is applied to video servers that have IP network connections with telephone network nodes. It should be understood that the video server includes, but is not limited to, servers with video processing capabilities, server clusters, and cloud servers such as dedicated clouds, private clouds, and public clouds.

[0031] The method includes:

[0032] 110: Receives the first video call sent by a telephone network node based on an IP network connection, the video call including the identifier of the first dialing device.

[0033] It should be understood that the telephone network in a telephone network node includes, but is not limited to, the Public Switched Telephone Network (PSTN), the Public Land Mobile Network (PLMN), etc. A telephone network node can include a gateway connecting the telephone network to an IP network. The Internet Protocol (IP) network is the Internet layer protocol in the TCP / IP architecture. Using IP networks improves network scalability. For example, it enables large-scale interconnection of heterogeneous networks and separates the coupling between top-level network applications and underlying network technologies, facilitating the independent development of both. In other words, a telephone network can be a non-IP network.

[0034] It should also be understood that telephone network nodes can be configured with an IP Multimedia Subsystem (IMS) to establish a media channel for video communication with the IP network. Messages received by the telephone network node from the dialing device (e.g., video call requests) conform to the communication protocols (e.g., statutory or de facto standard protocols) of the telephone operator deploying the aforementioned telephone network. The telephone operator provides IP network communication traffic services and IP video telephony services through the telephone network. Initiating a video call corresponds to the IP video telephony service.

[0035] It should also be understood that dialing devices can include mobile phones, landlines, and any electronic device with landline functionality.

[0036] It should also be understood that receiving a first video call call sent by a telephone network node via an IP network connection can refer to receiving a first video call call initiated by a first dialing device forwarded by the telephone network node via an IP network connection. In other words, the first dialing device sends a first video call call to the telephone network node, and then the telephone network node forwards it to the video server. During this forwarding process, the telephone network node can use an IMS system to change the communication protocol of the first video call call from the telephone network's communication protocol to an IP communication protocol, and then send the video call call over the IP network.

[0037] 120: In response to the first video call call, determine the first video channel with the first dialing device and the second video channel with the first IP terminal device and the second IP terminal device, wherein the first dialing device and the telephone network node are located within the telephone network, and the first IP terminal device and the second IP terminal device and the video server are located within the IP network.

[0038] It should be understood that the video server belongs to the same service architecture as the first IP terminal device and the second IP terminal device. For example, the video server can be a dedicated video processing device for the first and second IP terminal devices. Alternatively, the video server can also be a third-party video server other than the first and second IP terminal devices. Before the dialing device initiates a video call, at least one of the first and second IP terminal devices can have a connection with the video server based on the second video channel.

[0039] It should also be understood that responding to a first video call call and determining a first video channel and a second video channel can include the following implementations: In a first example, responding to a first video call call may involve establishing a first video channel and determining a second video channel, wherein the second video channel is established before the first video call call is received. In a second example, responding to a first video call call may involve establishing both a first video channel and a second video channel.

[0040] It should also be understood that at least one of the first video channel and the second video channel described above can be established using the Session Initiation Protocol (SIP); other media channel establishment protocols can also be used, and this embodiment of the invention does not limit this.

[0041] 130: Channel fusion is performed on the first video channel and the second video channel to establish a multi-party video call between the first dialing device and multiple IP terminal devices.

[0042] It should be understood that channel fusion of the first and second video channels allows monitoring of the data transmitted through the first video channel and the second video channels of both the first and second IP terminal devices. The data from the three video channels can be merged in real time before being sent to the corresponding devices for each video channel. Alternatively, a video channel can be established between the dialing device and the first IP terminal device based on the first video channel and the second video channel of the first IP video terminal device, and a video channel can also be established between the dialing device and the second IP terminal device based on the second video channels of both devices. These two video channels can then be monitored for channel fusion.

[0043] In the embodiment of the present invention, since the video server connected to the telephone network node via an IP network establishes a video channel with the dialing device located in the same telephone network node, the transmission of video data between the IP network and the telephone network is realized. In addition, since multiple IP terminal devices can be configured with their own video channels within the IP network, multi-party video calls between multiple IP terminal devices and the dialing device are realized, improving the video service capabilities of the IP network and the telephone network and saving communication costs.

[0044] In other words, communication between the dialing device and the telephone network node is based on the video telephony protocol (the protocol in 5G telephone networks). Communication between the telephone network node and the video server is based on the IP network. Communication between the video server and the IP terminal device is based on the IP network. Specifically, the telephone network node receives a video call from the dialing device based on the video telephony protocol and forwards the video call to the video server via the IP network. The video server responds to the video call by sending a session request to the telephone network node via the IP network. The telephone network node receives the session request via the IP network and forwards the session request to the dialing device based on the video telephony protocol. The dialing device responds to the session request by sending a session acknowledgment to the telephone network node based on the video telephony protocol. The telephone network node forwards the session acknowledgment via the IP network.

[0045] In some examples, the first video channel with the first dial-up device can be established after the second video channel with the first IP terminal device and the second IP terminal device has been established. Alternatively, the second video channel with the first IP terminal device and the second IP terminal device can be established after the first video channel with the first dial-up device has been established.

[0046] In other examples, a second video channel can be established simultaneously with the first IP terminal device and the second IP terminal device in response to a video call request. Alternatively, a video call can be established with the first IP terminal device, and then the second IP terminal device can be added to the video call. For example, in the case of a video call based on a first media channel of a first dial-up device and a second media channel of a first IP terminal device, the method may further include: responding to a video call call and notifying the first dial-up device and the first IP terminal device that the second IP terminal device is about to join, for example, by sending an identifier of the second IP terminal device to the first dial-up device and the first IP terminal device. The local video processing modules of the first dial-up device and the first IP terminal device can respond to the identifier and adjust the video window, etc. The first dial-up device and the first IP terminal device can respond to the identifier to monitor their local network environment and report it to the video server. The video server can send a session request to the second IP terminal device to establish a second video channel with the second IP terminal device if both the first dial-up device and the first IP terminal device are ready for a multi-party video call.

[0047] In other examples, the same communication method can be used when the above-mentioned multi-party video caller is added to the second dialing device, which will not be elaborated in the examples of this invention.

[0048] In another implementation of the present invention, in response to a first video call call, determining a first video channel with a first dialing device includes: in response to the first video call call, sending a session request to a telephone network node based on an IP network connection, wherein the session request includes an identifier of the video server; receiving a session confirmation sent by the telephone network node based on the IP network connection, and establishing a first video channel, wherein the session confirmation includes an identifier of the first dialing device.

[0049] Since the first video call was responded to, a first video channel was established via a session request, and thus the establishment of the first video channel was achieved through convenient interaction.

[0050] In another implementation of the present invention, channel fusion of the first video channel and the second video channel includes: acquiring video call data of the first dialing device and video call data of the first IP terminal device and the second IP terminal device, respectively, based on the first video channel of the first dialing device and the second video channel of the first IP terminal device and the second IP terminal device; generating real-time synthesized call data based on the video call data of the first dialing device, the first IP terminal device and the second IP terminal device; and sending the synthesized real-time synthesized call data to the first dialing device, the first IP terminal device and the second IP terminal device, respectively, based on the first video channel of the first dialing device and the second video channel of the first IP terminal device and the second IP terminal device.

[0051] Because video data acquired from various video channels can be synthesized and processed to achieve the fusion of various video channels, multi-party video calls can be realized without modifying the network architecture for multi-party calls.

[0052] In another implementation of the present invention, channel fusion of the first video channel and the second video channel includes: acquiring video call data of the first dialing device and video call data of the first IP terminal device and the second IP terminal device based on the first video channel of the first dialing device and the second video channel of the first IP terminal device and the second IP terminal device, respectively; recording the video call data of the first dialing device, the first IP terminal device and the second IP terminal device as a target video file in real time and saving it locally.

[0053] The solution in this example can record video call data from the first dialing device, the first IP terminal device, and the second IP terminal device in real time as a target video file and save it locally, thus realizing a recording service in scenarios such as video customer service.

[0054] In another implementation of the present invention, in response to a first video call call, determining a second video channel between a first IP terminal device and a second IP terminal device includes: in response to the first video call call, querying the current service status of each agent terminal device in the IP network, wherein the current service status indicates whether the device is currently available or currently occupied; and determining the first IP terminal device and the second IP terminal device from the agent terminal devices whose current service status indicates that the device is currently available.

[0055] Since the first IP terminal device and the second IP terminal device are currently available devices determined from among the various agent terminal devices, services such as those in multi-agent customer service scenarios are enabled. For example, in a multi-agent customer service scenario, the first IP terminal device can serve as a technical service agent, and the second IP terminal device can serve as a customer service agent, thereby improving the service quality and efficiency of customer service.

[0056] In another implementation of the present invention, the method further includes: encapsulating a SIP session request using the WebSocket protocol; sending the SIP session request to the browser clients installed on the first IP terminal device and the second IP terminal device within the IP network; and receiving session confirmations sent by the respective browser clients based on the WebSocket protocol within the IP network to establish a second video transmission channel between the first IP terminal device and the second IP terminal device.

[0057] It should be understood that WebSocket is a protocol for full-duplex communication over a single TCP connection. Because SIP session requests and acknowledgments can reliably and efficiently establish video transmission channels within IP networks, and because the WebSocket protocol is compatible with browser client software frameworks, a second video channel is quickly established.

[0058] In another implementation of the present invention, the method further includes: acquiring a user inquiry from a first dialing device via a first video channel; identifying the user inquiry and determining a customer service response corresponding to the user inquiry; and returning the customer service response to the first dialing device via a first video transmission channel.

[0059] Because the video server can recognize user inquiries and integrate video channels, it balances video data processing efficiency and data communication efficiency.

[0060] In another implementation of the present invention, the method further includes: responding to a second video call call, determining a third video channel with the second dialing device, wherein the second dialing device and the telephone network node are located within the telephone network, and performing channel fusion on the first video channel, the second video channel and the third video channel to add the second dialing device to the multi-party video call.

[0061] Because it is possible to merge the first, second, and third video channels, it enables the addition of new communication devices in multi-party video communication.

[0062] Figure 2A This is a schematic interaction diagram illustrating a communication method according to another embodiment of the present invention. The interaction diagram in this example relates to the interaction process between a dialing device, a network node configured with an IMS system telephone, a video server, agent terminal A as a first IP terminal device, and agent terminal B as a second IP terminal device.

[0063] It should be understood that the method in this example may include more or fewer steps, or may include alternative steps, and this example does not limit this.

[0064] It should also be understood that a telephone network node configured with IMS can act as a telephone network gateway connected to an IP network. In other words, a dialing device (e.g., the first dialing device described above) can be located in the telephone network along with the telephone network node. The telephone network node can be located in the IP network along with the video server, agent terminal A, and agent terminal B, wherein the telephone network node has an IP network connection with the video server, and the telephone network node can have an IP network connection with at least one of agent terminal A and agent terminal B, or it can have no IP network connection with either of them.

[0065] In step 2101, the dialing device initiates a video call to a telephone network node.

[0066] In step 2102, the telephone network node forwards the video call to the video server.

[0067] In step 2103, the video server sends a first session request to the telephone network node.

[0068] In step 2104, the video server sends a second session request to agent terminal A.

[0069] In step 2105, the telephone network node forwards the first session request to the dialing device.

[0070] In step 2106, agent terminal A sends a second session confirmation to the video server.

[0071] In step 2107, the video server sends a second session request to agent terminal B.

[0072] In step 2108, the dialing device sends a first session confirmation to the telephone network node.

[0073] In step 2109, the telephone network node sends a first session acknowledgment to the video server. Specifically, the first session acknowledgment is a response to the first session request.

[0074] In step 2110, agent terminal B sends a second session confirmation to the video server. Specifically, the second session confirmation is a response to the second session request.

[0075] In step 2111, a first video channel is established between the dialing device and the video server. Specifically, the first video channel can be established in response to the receipt of a first session acknowledgment.

[0076] In step 2112, a second video channel is established between the video server and agent terminals A and B. Specifically, the second video channel can be established in response to the receipt of a second session acknowledgment.

[0077] In step 2113, the first video channel and the second video channel are fused to establish a multi-party video call. Specifically, after the video channel established later in time in the first video call and the second video channel is established, the video server can monitor the transmitted data in the first video channel and the second video channel and generate real-time merged video data. For example, the real-time merged video data can be encapsulated into a data packet sequence using a specific data encapsulation format.

[0078] Figure 2BThis is a schematic interaction diagram illustrating a communication method according to another embodiment of the present invention. The interaction diagram in this example relates to the interaction process between a dialing device, a network node configured with an IMS system telephone, a video server, agent terminal A as a first IP terminal device, and agent terminal B as a second IP terminal device.

[0079] It should be understood that the method in this example may include more or fewer steps, or may include alternative steps, and this example does not limit this.

[0080] It should also be understood that a telephone network node configured with IMS can act as a telephone network gateway connected to an IP network. In other words, a dialing device (e.g., the first dialing device described above) can be located in the telephone network along with the telephone network node. The telephone network node can be located in the IP network along with the video server, agent terminal A, and agent terminal B, wherein the telephone network node has an IP network connection with the video server, and the telephone network node can have an IP network connection with at least one of agent terminal A and agent terminal B, or it can have no IP network connection with either of them.

[0081] In the previous example, the first video channel and the second video channel were established simultaneously. In response to the video call call, a first session request was sent to the telephone network node, and in response to the video call call, a second session request was sent to at least one of agent terminal A and agent terminal B.

[0082] In this example, the second video channel is completed before the video call is initiated.

[0083] In step 2101, the telephone network node forwards the video call to the video server.

[0084] In step 2102, agent terminal A sends a second session confirmation to the video server.

[0085] In step 2103, the video server sends a second session request to agent terminal B.

[0086] In step 2114, agent terminal B sends a second session confirmation to the video server.

[0087] In step 2115, a second video channel is established between the video server and agent terminals A and B.

[0088] In step 2106, the dialing device initiates a video call to the telephone network node.

[0089] In step 2107, the video server sends a first session request to the telephone network node.

[0090] In step 2108, the video server sends a second session request to agent terminal A.

[0091] In step 2109, the telephone network node forwards the first session request to the dialing device.

[0092] In step 2110, the dialing device sends a first session confirmation to the telephone network node.

[0093] In step 2111, the telephone network node sends a first session confirmation to the video server.

[0094] In step 2112, a first video channel is established between the dialing device and the video server.

[0095] In step 2113, the first video channel and the second video channel are fused to establish a multi-party video call.

[0096] Figure 3 This is a schematic flowchart illustrating a communication method according to another embodiment of the present invention. Figure 3 The communication method is applied to video servers that have IP network connections with telephone network nodes. It should be understood that the video server includes, but is not limited to, servers with video processing capabilities, server clusters, and cloud servers such as dedicated clouds, private clouds, and public clouds.

[0097] The method includes:

[0098] 310: Obtain video call calls sent by IP terminal devices, where the IP terminal devices and video servers are located within an IP network;

[0099] 320: In response to a video call call, determine a first media channel with a first dialing device and a second dialing device, and a second media channel with an IP terminal device, wherein the first dialing device and the second dialing device are located within a telephone network;

[0100] 330: Channel fusion of the first media channel and the second media channel to establish a multi-party video call between IP terminal devices, the first dialing device, and the second dialing device.

[0101] In the embodiment of the present invention, since the video server connected to the telephone network node via an IP network establishes a video channel with the dialing device located in the same telephone network node, the transmission of video data between the IP network and the telephone network is realized. In addition, since multiple IP terminal devices can be configured with their own video channels within the IP network, multi-party video calls between multiple IP terminal devices and the dialing device are realized, improving the video service capabilities of the IP network and the telephone network and saving communication costs.

[0102] In other words, communication between the dialing device and the telephone network node is based on the video telephony protocol (the protocol in 5G telephone networks). Communication between the telephone network node and the video server is based on the IP network. Communication between the video server and the IP terminal device is based on the IP network. Specifically, the telephone network node receives a video call from the dialing device based on the video telephony protocol and forwards the video call to the video server via the IP network. The video server responds to the video call by sending a session request to the telephone network node via the IP network. The telephone network node receives the session request via the IP network and forwards the session request to the dialing device based on the video telephony protocol. The dialing device responds to the session request by sending a session acknowledgment to the telephone network node based on the video telephony protocol. The telephone network node forwards the session acknowledgment via the IP network.

[0103] It should be understood that the IMS system in the various embodiments of the present invention can be deployed in any network node of the 5G core network.

[0104] In some examples, in response to a video call call, a first media channel is established between the first dialing device and the second dialing device. The video call call includes an identifier of the second dialing device. The video server may have a first media channel with the first dialing device and, based on the identifier of the second dialing device, establishes a first media channel (e.g., a first video channel) with the second dialing device to enable multi-party video calls.
