Description

Technical Field

[0001] The present application relates to the field of communication technology, and in particular to a service collaboration method, apparatus, device, and medium. Background Art

[0002] Based on existing audio calls, the network can initiate video media renegotiation with the caller or called party based on service needs, and use the successfully negotiated video media channel to complete the corresponding video playback service. However, in real-world applications, different services and call parties may undergo multiple media renegotiations, which reduces the immediacy of service initiation. For example, different services signed by the local and remote users may simultaneously request service provision through a video media channel from one party in the call. Therefore, existing technologies may cause service conflicts when multiple concurrent calls are made, resulting in low service collaboration efficiency. Summary of the Invention

[0003] The embodiments of the present application provide a service collaboration method, apparatus, device, and medium to solve the problem in the prior art of service conflicts when multiple call services are concurrent, thereby resulting in low service collaboration efficiency.

[0135] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0136] In the embodiments of the present application, a business collaboration method, apparatus, device and medium are proposed to solve the problem of low efficiency of existing business collaboration.

[0137] See also Figure 1 , Figure 1 This is one of the flow charts of a service collaboration method provided in an embodiment of the present application, which is applied to a first network element, such as Figure 1 As shown, the method includes the following steps:

[0138] Step 101: When a first terminal calls a second terminal and the second terminal goes off-hook, an update message sent by a second network element corresponding to the second terminal is received, where the update message is used to instruct a first peer service of the second terminal to apply for a video media channel from the first terminal.

[0139] It should be understood that the first terminal is the calling terminal, the second terminal is the called terminal, and the second terminal's off-hook action can be the called party answering the call. The update message can be a message used to update the call status and can carry a pre_200_OK parameter to indicate that the update message is sent in response to a call event in which the second terminal off-hook (200OK). The first peer service can be a service subscribed to by the second terminal that requires a video media channel request from the first terminal, providing the corresponding call service to the second terminal after the second terminal off-hook.

[0140] Step 102: When the first terminal has at least one local service, a first event notification is sent to a first service application server corresponding to the first terminal, where the first event notification is used to instruct the second terminal to go off-hook.

[0141] It should be understood that the local service may be a call service subscribed by the first terminal. The first service application server (AS) may be a server for providing the corresponding local service to the first terminal after the second terminal goes off-hook.

[0142] Step 103: Receive a first call control message sent by the first service application server in response to the first event notification, where the first call control message is used to indicate whether the at least one local service applies for the video media channel.

[0143] It should be understood that some of the at least one local service may require the video media channel, such as video playback services, etc. Which local services require the video media channel can be determined based on the first call control message.

[0144] Step 104: Determine a video playback port according to the first call control message and the update message.

[0145] It should be understood that the above-mentioned video playback port may be a specific port used to play the video stream during a call, and the above-mentioned determination of the video playback port may be a determination of a call service using the video media channel.

[0146] Step 105: Establish a call between the first terminal and the second terminal according to the video playback port.

[0147] It should be understood that the above-mentioned establishment of a call between the first terminal and the second terminal may be an audio call established by both parties, and the video playback port plays the video on the outgoing call screen of the first terminal, specifically the corresponding service AS controls the video playback port of the media plane node to play the video.

[0148] For example, Figure 2 This is an interactive diagram of a service collaboration method provided by an embodiment of the present application, wherein the first network element is a VoNR+ capable network element on the calling side, and the second network element is a VoNR+ capable network element on the called side, such as Figure 2 As shown in steps 1-9, the calling terminal dials the called terminal. After the called terminal picks up the phone, it receives an update (UPDATE) message sent by the VoNR+ capability network element on the called side. The VoNR+ capability network element on the calling side determines that the second terminal is applying for the use of the video channel to the calling terminal for a call event based on the parameters (pre_200_OK) in the UPDATE message. Therefore, a call event notification is sent to each service AS on the calling side in advance. After each service AS returns the call control request, it determines the video playback port according to the first call control message and the update message, and establishes a call between the first terminal and the second terminal.

[0149] In an embodiment of the present application, the above-mentioned service collaboration method is applied to the first network element. After receiving the update message sent by the second network element corresponding to the second terminal, the first network element can directly send a first event notification to the first service application server corresponding to the first terminal, instructing the second terminal to pick up the phone, and receive the first call control message sent by the first service application server in response to the first event notification, determine the video playback port, and establish a call between the first terminal and the second terminal. After receiving the update message, the first network element does not forward the update message to the first terminal for media renegotiation first, but directly sends the first event notification to the first service application server. In this way, when the services of the first terminal and the second terminal apply for video media channels at the same time, multiple media renegotiations can be avoided, call delay can be reduced, and the collaboration efficiency of call services can be improved.

[0150] Optionally, determining a video playback port according to the first call control message and the update message includes:

[0151] determining, according to the first call control message, whether any local service among the at least one local service applies for the video media channel;

[0152] In a case where a local service among the at least one local service applies for the video media channel, determining at least one first local service that applies for the video media channel;

[0153] According to the preset priority of the at least one first local service, the media port of the second local service is determined to be the video playback port, and the second local service has the highest priority among the at least one first local service.

[0154] Specifically, among the at least one local service, there may be a local service that requires application for the video media channel. For example, if the local service is to push a video stream to the outgoing call screen of the first terminal, then the call control message corresponding to the local service is to apply for use of the video media channel for video stream push. Since there may be multiple first local services that require application for the video media channel among the at least one local service, the first local service to use the video media channel is determined based on priority.

[0155] It should be understood that the above-mentioned priority can be the default setting of the call system or a user-defined priority order, specifically the priority order of the at least one first local service. If the at least one first local service needs to apply for the video playback channel, only the first local service with the highest priority can use the video media channel. The above-mentioned determination that the media port of the second local service is the video playback port can be understood as controlling the second local service to use the video media channel.

[0156] For example, Figure 2 is an interactive diagram of a service collaboration method, wherein the first network element is a VoNR+ capable network element on the calling side, and the second network element is a VoNR+ capable network element on the called side, such as Figure 2 As shown in steps 10b-14b in , if the VoNR+ capable network element on the calling side finds that there is a video media channel request on the local side, it cancels the video channel media request on the called side, and the VoNR+ capable network element on the called side sends 200OK (INVITE) to the VoNR+ capable network element on the calling side. The VoNR+ capable network element on the calling side updates the video media channel for the service with the highest priority right to use the video channel on the local side according to the system priority control module and user priority control module of the collaborative device, and forwards 200OK (INVITE). After the calling terminal responds with ACK, the calling side node plays the video to the calling terminal, and a two-way audio call is established between the calling terminal and the called terminal.

[0157] In this embodiment, the above-mentioned business collaboration method can directly determine that the local business uses the video media channel when the local business and the opposite business apply for the video media channel at the same time, and in the case of a conflict between multiple local businesses, the local business that uses the video media channel is determined according to a preset priority order. In addition, in the case of a business conflict, the business that uses the video media channel can be quickly determined, thereby further improving the collaboration efficiency in the event of a business conflict.

[0158] Optionally, after determining whether any local service among the at least one local service applies for the video media channel, the method further includes:

[0159] In a case where no local service in the at least one local service applies for the video media channel, the media port of the first opposite-end service is determined as the video playback port according to the update message.

[0160] It should be understood that, when there is no local service in at least one local service that applies for the video media channel, the local service signed by the first terminal does not need to apply for the video media channel, and there is no service conflict between the local service and the opposite service. That is, by applying for the video media channel at the same time, the media port of the first opposite service can be directly determined as the video playback port.

[0161] For example, Figure 2As shown in steps 10a-14a in FIG, the VoNR+ capable network element on the calling side finds that there is no video media channel request on the local end, so it allows the video media channel request on the called side. After the calling terminal successfully responds, the VoNR+ capable network element on the called side sends a 200OK (INVITE) to the VoNR+ capable network element on the calling side. The VoNR+ capable network element on the calling side sends a 200OK (INVITE) to the calling terminal. After the calling terminal replies with an ACK, the called side node plays the video to the calling terminal, and a two-way audio call is established between the calling terminal and the called terminal.

[0162] In this implementation, the service collaboration method can directly determine that the first opposite-end service uses the video media channel when the local-end service does not apply for the video media channel, thereby further improving the collaboration efficiency of the call service.

[0163] Optionally, the update message further includes service list information, where the service list information is used to indicate at least one second peer service of the second terminal. After establishing a call between the first terminal and the second terminal according to the video playback port, the method further includes:

[0164] According to the update message and the first call control message, the media plane node corresponding to the first terminal is controlled to display first service information, where the first service information is used to indicate the available services of the first terminal and the startup method of the available services. The available services include the at least one second opposite-end service and at least one third local-end service, where the third local-end service is a local-end service in the at least one first local-end service excluding the second local-end service.

[0165] It should be understood that the service list information may be used to indicate other call services that the second terminal can provide to the first terminal that require the use of the video media channel. The at least one second peer service is different from the first peer service.

[0166] Exemplarily, the update (UPDATE) message carries a list of other applications (available_service_list) on the called side that currently provide video channel services. The application list includes the identifier of each service (appid), the call session identifier (callid), and the access address (appaddress) providing services for the call.

[0167] The above-mentioned first service information is used to indicate that in addition to the call service currently using the video media channel, the first terminal can also select other call services that require the use of the video media channel. The above-mentioned available services may include other call services that the second terminal can provide to the first terminal that require the use of the video media channel, and may also include other call services that the first terminal itself has signed a contract for that require the use of the video media channel, that is, the third local service.

[0168] Specifically, controlling the media plane node corresponding to the first terminal to display the first service information may include displaying the first terminal's available services and activation methods on the first terminal's outgoing call screen. For example, the first network element may control the media plane to play a video stream to the user and prompt the user of other services that currently provide video channel services and their activation methods, such as activation via keywords or dial pad buttons.

[0169] In this embodiment, the update message also includes service list information, and the service list information is used to indicate at least one second-end service of the second terminal. The above-mentioned service collaboration method can control the media interface node corresponding to the first terminal to display the first service information based on the update message and the first call control message. The first service information is used to indicate the available services of the first terminal and the startup method of the available services, so that the user can switch the call service according to the specific needs during the call, thereby improving the convenience of the user in using the call service.

[0170] Optionally, after controlling the media plane node corresponding to the first terminal to display the first service information, the method further includes:

[0171] When the first control request is received, a first service request is sent to the first service application server, where the first control request is used to request to start a local service among the available services;

[0172] receiving a second call control message sent by the first service application server in response to the first service request;

[0173] According to the second call control message, the video playback port is updated to the media port of the local service corresponding to the first control request.

[0174] It should be understood that the first control request may be a message sent by the first terminal to the first network element in response to an operation of switching a local service by a user of the first terminal.

[0175] For example, Figure 2As shown in steps 15a-18a in FIG, if the user controls the switching of other call services on the calling side, the VoNR+ capable network element on the calling side sends a call to the corresponding service after receiving the control request. AS After receiving the service request, the service AS controls the VoNR+ capable network element on the calling side to update the video media channel, and the calling side node updates the video playback content.

[0176] In this embodiment, the above-mentioned business collaboration method can send a first business request to the first business application server upon receiving a first control request, and receive a second call control message sent by the first business application server in response to the first business request. According to the second call control message, the video playback port is updated to the media port of the local service corresponding to the first control request, and then the corresponding local service can be provided to the user according to the user's operation of switching the local service, thereby meeting the user's needs, thereby further improving the convenience of the user in using the call service.

[0177] Optionally, the method further includes:

[0178] In the case of receiving the second control request, a second service request is sent to the second service application server, where the second control request is used to request to start a peer service among the available services.

[0179] It should be understood that the second control request may be a message sent by the first terminal to the first network element in response to an operation of switching the opposite terminal service by the user of the first terminal.

[0180] For example, Figure 2 As shown in steps 15b-18b, if the user controls the switching of other call services on the called side, the VoNR+ capability network element on the calling side forwards the service request to the corresponding call session of the service AS of the second terminal by updating the parameters of the available service list (available_service_list) in the (UPDATE) message after receiving the service request. After receiving the service request, the service AS controls the VoNR+ capability network element on the called side to update the video media channel, and the called side node updates the video playback content.

[0181] In this embodiment, the above-mentioned service collaboration method can send a second service request to the second service application server upon receiving a second control request. The second control request is used to request the start of the peer service among the available services, and then provide the user with the corresponding peer service based on the user's operation of switching the peer service, thereby meeting the user's needs, thereby further improving the convenience of the user in using the call service.

[0182] Optionally, the first network element includes a service collaboration device, Figure 3 This is a schematic diagram of the structure of a business collaboration device provided in an embodiment of the present application. Figure 3 As shown, the service collaboration device includes a system priority control module, a user priority control module, a local priority control module and a service switching management and control module;

[0183] The system priority control module is used to determine the media port of the local service with the highest priority as the video playback port according to a preset priority order when multiple local services apply for video media channels at the same time;

[0184] The user priority control module is configured to, when multiple local services simultaneously apply for video media channels and the user-defined priority order is different from the preset priority order, determine, according to the user-defined priority order, the media port of the local service with the highest priority as the video playback port;

[0185] The local priority control module is configured to determine the media port of the local service as the video playback port when the local service and the peer service simultaneously apply for a video media channel;

[0186] The service switching management and control module is configured to control the media plane node corresponding to the first terminal to display first service information after a call between the first terminal and the second terminal is established, where the first service information is used to indicate available services of the first terminal and a method for activating the available services;

[0187] In the case of receiving the control request, a service request is sent to the first service application server or the second service application server, where the control request is used to request to start the available service.

[0188] It should be understood that the above-mentioned business collaboration device can be a control strategy corresponding to the above-mentioned business collaboration method. Specifically, the call system can set a default priority for each local service. When multiple services simultaneously apply for negotiation to use the video media channel, the system priority control module controls that only the service with the highest priority can use the video media channel. The user can also modify the system default priority. When the user priority is different from the system priority, the user priority control module is used to control the processing according to the user priority. When the opposite-end service and the local service apply for the use of the video media channel at the same time, the local priority control module controls to provide only the video channel for the local service and rejects the request of the opposite-end service. During the call, the service switching management and control module manages other video playback services that can be used in the local and opposite-end call systems in the current state of the call; it can prompt the user of other video playback services that are currently available and their startup methods according to the strategy; when receiving a user application to start or switch to other services, it sends a corresponding event notification to the local or opposite-end service AS.

[0189] In this embodiment, the above-mentioned service collaboration method can solve the problem of video media channel negotiation conflict and reduce call delay by setting the service collaboration device in the first network element, when multiple services collaboratively apply for video media channels.

[0190] It should be noted that the embodiment of the present application is explained by applying for a video channel from the outgoing call screen of the calling terminal (i.e., the caller is the local node and the called party is the opposite node). The process of applying for a video channel from the incoming call screen of the called terminal is similar to the process of this solution (i.e., the caller is the opposite node and the called party is the local node). Therefore, this will not be repeated in this application.

[0191] See also Figure 4 , Figure 4 This is a second flow chart of a service collaboration method provided in an embodiment of the present application, which is applied to a second network element, such as Figure 4 As shown, the method includes the following steps:

[0192] Step 401: When a first terminal calls a second terminal and the second terminal goes off-hook, a second event notification is sent to a second service application server corresponding to the second terminal, where the second event notification is used to instruct the second terminal to go off-hook.

[0193] Step 402: Receive a third call control message sent by the second service application server in response to the second event notification, where the third call control message is used to indicate whether at least one peer service of the second terminal applies for a video media channel from the first terminal.

[0194] Step 403: Determine an update message according to the third call control message, where the update message is used to instruct the first peer service of the second terminal to apply for the video media channel.

[0195] Step 404: Send the update message to the first network element.

[0196] It should be understood that the peer service may be a call service subscribed by the second terminal. The second service application server (AS) may be a server for providing the corresponding peer service to the second terminal after the second terminal goes off-hook.

[0197] It should be noted that this embodiment is Figure 1 The implementation method of the corresponding second network element in the embodiment shown in the figure can be found in the specific implementation method. Figure 1 To avoid duplication, the relevant descriptions in the illustrated embodiment will not be repeated in this embodiment.

[0198] Optionally, determining an update message according to the third call control message includes:

[0199] determining, according to the third call control message, whether at least one peer service has applied for the video media channel;

[0200] In a case where any one of the at least one peer service applies for the video media channel, determining at least one third peer service that applies for the video media channel;

[0201] An update message is determined according to a preset priority of the at least one third peer service, wherein the update message is used to instruct the first peer service to apply for the video media channel, and the first peer service has the highest priority among the at least one third peer service.

[0202] It should be understood that some of the at least one peer service may require the video media channel, such as video playback services, etc. Which peer services require the video media channel can be determined based on the third call control message.

[0203] It should be understood that the priority can be the default setting of the call system or a user-defined priority order, specifically the priority order of at least one third-end service. In the case where at least one third-end service needs to apply for the video playback channel, only the third-end service with the highest priority can apply to the first terminal for the use of the video media channel.

[0204] For example, Figure 2As shown in steps 1-7, after the called terminal picks up the phone, it sends 200OK (INVITE) to the VoNR+ capability network element on the called side. The VoNR+ capability network element on the called side forwards the call event notification to the service ASs registered by the called terminal. Each service AS returns the corresponding call control request according to the service logic. The VoNR+ capability network element on the called side updates the video media channel for the service with the highest priority usage right of the video channel according to the system priority control module and user priority control module of the service collaboration device, and sends an update message to the VoNR+ capability network element on the calling side to apply for the use of the video media channel.

[0205] Optionally, the update message further includes service list information, where the service list information is used to indicate at least one second peer service of the second terminal, where the second peer service is a peer service in the at least one third peer service except the first peer service.

[0206] Optionally, the method further includes:

[0207] receiving a fourth call control message sent by the second service application server in response to the second service request;
