[0085] Currently, Voice over Long-Term Evolution (VoLTE) or Voice over New Radio (VoNR) based on IMS technology primarily focus on audio and video communication, supporting voice calls, video calls, and telephone services such as HD voice, intelligent networks, and Centrex. With increasing bandwidth, over-the-top (OTT) audio and video applications from internet companies are experiencing explosive growth, providing users with increasingly rich services. OTT products are gradually cultivating users' demands for diversified, multi-dimensional, and social communication products, with users expecting to transmit more interactive information during audio and video calls. Among related technologies, VoLTE / VoNR telephone services based on IMS cannot transmit other information during audio and video calls, failing to meet the diverse communication needs of end users.

[0086] Based on this, embodiments of this application provide a data interaction method, apparatus, terminal, network device, and storage medium. In this method, when a VoIMS call is established, a first network device sends a first request to a first server corresponding to the VoIMS call, requesting the establishment of an interactive data channel with the calling and called terminals of the VoIMS call. Based on the first request, the first server sends a second request to both the calling and called terminals of the VoIMS call, requesting the corresponding terminals to establish an interactive data channel with the first network device. Based on the first responses received from the first and second terminals, the first server sends a first notification to the first network device. Here, the first notification indicates whether the calling and called terminals of the VoIMS call support interactive data channel capabilities. If the received first notification indicates that the calling and / or called terminals of the VoIMS call support interactive data channel capabilities, the first network device establishes an interactive data channel with the corresponding terminals. Through this scheme, the terminal can perform data interaction based on the interactive data channel while conducting a VoIMS call, ensuring the diverse communication needs of terminal users.

[0087] The present application will now be described in further detail with reference to the accompanying drawings and embodiments.

[0088] first, Figure 1 The architecture of the data interaction system according to an embodiment of this application is shown, with reference to Figure 1 This system architecture, based on the VoIMS calling system architecture consisting of terminals and a VoIMS application server, introduces an interactive calling platform. In other words, the data interaction system includes: the interactive calling platform, the VoIMS application server, and the terminals. In practical applications, the interactive calling platform is functionally divided into two modules: business and media. These modules can be logically or physically separated. The business module is responsible for business logic processing and business management, while the media module is responsible for establishing an interactive data channel with the terminals to complete data exchange. Here, the interactive calling platform and the VoIMS application server are deployed independently, without affecting basic audio and video call services, thus ensuring call security.

[0089] based on Figure 1 The architecture of the data interaction system is shown. Figure 2 This illustration shows the implementation flow of a data interaction method provided in an embodiment of this application, which is applied to a first network device. Here, the first network device can be understood as... Figure 1 The interactive call platform in the data interaction system shown. See also... Figure 2 The method includes:

[0090] Step 201: In the case of a VoIMS call being established, send a first request to the first server corresponding to the VoIMS call.

[0091] The first request is used to request the establishment of an interactive data channel with the calling and called terminals of the VoIMS call.

[0092] In one embodiment, before sending a first request to the first server corresponding to the VoIMS call, the method further includes:

[0093] Receive the second notification sent by the first server; wherein,

[0094] The second notification is used to notify the first network device that the VoIMS call has been established.

[0095] In practical applications, when a VoIMS call is established between the calling terminal and the called terminal, the corresponding VoIMS application server, i.e., the first server, sends a call event notification to the interactive call platform. After receiving the call event notification, the interactive call platform determines that it needs to actively create an interactive data channel, and thus sends a call event control request, i.e., the first request, to the VoIMS application server, requesting to establish interactive data channels with both the calling terminal and the called terminal.

[0096] In one embodiment, the first request carries first information; the first information represents the media negotiation parameters of the first network device.

[0097] In one embodiment, the first information includes at least one of the following:

[0098] The endpoint IP address and / or port number of the interactive data channel;

[0099] Media parameters for the interactive data channel;

[0100] Substreams of the interactive data channel;

[0101] Sub-protocol of the interactive data channel.

[0102] After receiving the first request, the first server sends a second request to the calling terminal of the VoIMS call, requesting the calling terminal to establish an interactive data channel with the first network device. Upon receiving the second request, the calling terminal returns a first response to the first server regarding the second request, thus informing the first server whether the calling terminal supports the interactive data channel capability. Similarly, after receiving the first request, the first server also sends a second request to the called terminal of the VoIMS call, requesting the called terminal to establish an interactive data channel with the first network device. Upon receiving the second request, the called terminal returns a first response to the first server, thus informing the first server whether the called terminal supports the interactive data channel capability. Based on the first responses from both the calling and called terminals, the first server sends a first notification to the first network device, thereby informing the first network device whether the calling and called terminals support the interactive data channel capability.

[0103] Step 202: Receive the first notification from the first server.

[0104] The first notification indicates whether the calling terminal and the called terminal of the VoIMS call support interactive data channel capability.

[0105] Step 203: If the received first notification indicates that the calling terminal and / or called terminal of the VoIMS call support interactive data channel capability, establish an interactive data channel with the corresponding terminal.

[0106] Here, when the first notification from the first server indicates that both the calling terminal and the called terminal in the VoIMS call support interactive data channel capabilities, the first network device establishes interactive data channels with both the calling terminal and the called terminal respectively; when the first notification from the first server indicates that the calling terminal supports interactive data channel capabilities but the called terminal does not, the first network device establishes an interactive data channel with the calling terminal but not with the called terminal; when the first notification from the first server indicates that the calling terminal does not support interactive data channel capabilities but the called terminal does, the first network device does not establish an interactive data channel with the calling terminal but establishes an interactive data channel with the called terminal.

[0107] Accordingly, based on Figure 1 The architecture of the data interaction system is shown. Figure 3 This illustration shows the implementation flow of a data interaction method provided in an embodiment of this application, which is applied to a first server. Here, the first server can be understood as... Figure 1 The VoIMS application server in the data interaction system shown. See also... Figure 3 The method includes:

[0108] Step 301: Receive the first request sent by the first network device.

[0109] The first request is issued when a VoIMS call is established; the first request is used to request the establishment of an interactive data channel with the calling and called terminals of the VoIMS call.

[0110] In practical applications, when a VoIMS call is established between the calling terminal and the called terminal, the corresponding VoIMS application server, i.e., the first server, sends a call event notification to the interactive call platform. After receiving the call event notification, the interactive call platform determines that it needs to actively create an interactive data channel, and thus sends a call event control request, i.e., the first request, to the VoIMS application server, requesting to establish interactive data channels with both the calling terminal and the called terminal.

[0111] Step 302: Based on the first request, send a second request to the calling terminal and the called terminal of the VoIMS call.

[0112] The second request is used to request the corresponding terminal to establish an interactive data channel with the first network device.

[0113] After receiving the first request, the first server sends a second request to the calling terminal of the VoIMS call, requesting the calling terminal to establish an interactive data channel with the first network device. Upon receiving the second request, the calling terminal returns a first response to the first server regarding the second request, thus indicating whether the calling terminal supports the interactive data channel capability. Similarly, after receiving the first request, the first server also sends a second request to the called terminal of the VoIMS call, requesting the called terminal to establish an interactive data channel with the first network device. Upon receiving the second request, the called terminal returns a first response to the first server regarding the second request, thus indicating whether the called terminal supports the interactive data channel capability.

[0114] Step 303: Receive the first response returned by the first terminal and the second terminal based on the second request.

[0115] The first response indicates whether the corresponding terminal supports interactive data channel capabilities.

[0116] Step 304: Based on the received first response, send a first notification to the first network device.

[0117] The first notification indicates whether the calling terminal and the called terminal of the VoIMS call support interactive data channel capability.

[0118] Here, based on the first responses from the calling terminal and the called terminal, the first server sends a first notification to the first network device, thereby informing the first network device whether the calling terminal and the called terminal support interactive data channel capabilities. If the first notification from the first server indicates that both the calling terminal and the called terminal in the VoIMS call support interactive data channel capabilities, the first network device establishes interactive data channels with both the calling terminal and the called terminal respectively. If the first notification from the first server indicates that the calling terminal supports interactive data channel capabilities but the called terminal does not, the first network device establishes an interactive data channel with the calling terminal but not with the called terminal. If the first notification from the first server indicates that the calling terminal does not support interactive data channel capabilities but the called terminal does, the first network device does not establish an interactive data channel with the calling terminal but establishes an interactive data channel with the called terminal.

[0119] In this process, the second request sent by the first server to the terminal carries an interactive data channel capability tag. Based on this tag, the terminal knows that the first server is requesting it to establish an interactive data channel with the first network device. If the terminal supports the interactive data channel capability, the first server initiates a media negotiation request message to the terminal. This message carries the mobile phone number of the VoIMS call's peer terminal, audio and video media information, and media negotiation parameters for the interactive data channel supported by the first network device. The terminal returns a response to the media negotiation request message to the first server, carrying its own audio and video media information and the media negotiation parameters for the interactive data channel it supports.

[0120] It should be noted that in a VoIMS call, if one of the calling and called terminals does not support interactive data channel capability, it will not affect the other terminal that supports interactive data channel capability from establishing a data interaction channel with the first network device.

[0121] In one embodiment, both the first request and the second request carry first information; the first information represents the media negotiation parameters of the first network device.

[0122] In one embodiment, the first information includes at least one of the following:

[0123] The endpoint IP address and / or port number of the interactive data channel;

[0124] Media parameters for the interactive data channel;

[0125] Substreams of the interactive data channel;

[0126] Sub-protocol of the interactive data channel.

[0127] In one embodiment, the second request includes a Modify Session Request (SIP) for the Meeting Initiation Protocol; the first response includes a SIP 200 message.

[0128] In practical applications, the second request is represented as a re-INVITE request.

[0129] In one embodiment, the header field of the modified session request carries an interactive data channel service label; the SDP media line of the modified session request carries media negotiation parameters of the first network device; and when the first terminal supports interactive data channel capability, the SDP media line of the 200 message carries media negotiation parameters of the first terminal.

[0130] In this way, after receiving the first response, the first server can determine whether the terminal supports interactive data channel capability based on the media negotiation parameters supported by the terminal carried in the first response.

[0131] In one embodiment, before receiving the first request sent by the first network device, the method further includes:

[0132] In the event of a VoIMS call being established, a second notification is sent to the first network device; wherein...

[0133] The second notification is used to notify the first network device that the VoIMS call has been established.

[0134] In practical applications, when a VoIMS call is established between the calling terminal and the called terminal, the corresponding VoIMS application server, i.e., the first server, sends a call event notification to the interactive call platform. After receiving the call event notification, the interactive call platform determines that it needs to actively create an interactive data channel, and thus sends a call event control request, i.e., the first request, to the VoIMS application server, requesting to establish interactive data channels with both the calling terminal and the called terminal.

[0135] Accordingly, based on Figure 1 The architecture of the data interaction system is shown. Figure 4 This illustration shows the implementation flow of a data interaction method provided in an embodiment of this application, which is applied to a first terminal. Here, the first terminal can be understood as being based on... Figure 1 The data interaction system shown establishes a VoIMS call between the calling or called terminal. See also... Figure 4 The method includes:

[0136] Step 401: Receive the second request sent by the first server corresponding to the VoIMS call.

[0137] The second request is used to request the first terminal to establish an interactive data channel with the first network device.

[0138] In practical applications, when a VoIMS call is established between the calling terminal and the called terminal, the first server sends a second request to the calling terminal of the VoIMS call, requesting the calling terminal to establish an interactive data channel with the first network device. Similarly, the first server also sends a second request to the called terminal of the VoIMS call, requesting the called terminal to establish an interactive data channel with the first network device.

[0139] In one embodiment, each of the second requests carries first information; the first information represents the media negotiation parameters of the first network device.

[0140] In one embodiment, the first information includes at least one of the following:

[0141] The endpoint IP address and / or port number of the interactive data channel;

[0142] Media parameters for the interactive data channel;

[0143] Substreams of the interactive data channel;

[0144] Sub-protocol of the interactive data channel.

[0145] Step 402: Based on the second request, return a first response to the first server.

[0146] The first response indicates whether the first terminal supports interactive data channel capabilities.

[0147] In one embodiment, the second request includes a SIP Modify Session Request; the first response includes a SIP 200 message.

[0148] In practical applications, the second request is represented as a re-INVITE request.

[0149] In one embodiment, the header field of the modified session request carries an interactive data channel service label; the SDP media line of the modified session request carries media negotiation parameters of the first network device; and when the first terminal supports interactive data channel capability, the SDP media line of the 200 message carries media negotiation parameters of the first terminal.

[0150] In this way, after receiving the first response, the first server can determine whether the terminal supports interactive data channel capability based on the media negotiation parameters supported by the terminal carried in the first response.

[0151] Step 403: If the first terminal supports interactive data channel capability, establish an interactive data channel with the first network device.

[0152] Here, when the first notification from the first server indicates that both the calling terminal and the called terminal in the VoIMS call support interactive data channel capabilities, the first network device establishes interactive data channels with both the calling terminal and the called terminal respectively; when the first notification from the first server indicates that the calling terminal supports interactive data channel capabilities but the called terminal does not, the first network device establishes an interactive data channel with the calling terminal but not with the called terminal; when the first notification from the first server indicates that the calling terminal does not support interactive data channel capabilities but the called terminal does, the first network device does not establish an interactive data channel with the calling terminal but establishes an interactive data channel with the called terminal.

[0153] In this process, the second request sent by the first server to the terminal carries an interactive data channel capability tag. Based on this tag, the terminal knows that the first server is requesting it to establish an interactive data channel with the first network device. If the terminal supports the interactive data channel capability, the first server initiates a media negotiation request message to the terminal. This message carries the mobile phone number of the VoIMS call's peer terminal, audio and video media information, and media negotiation parameters for the interactive data channel supported by the first network device. The terminal returns a response to the media negotiation request message to the first server, carrying its own audio and video media information and the media negotiation parameters for the interactive data channel it supports.

[0154] It should be noted that in a VoIMS call, if one of the calling and called terminals does not support interactive data channel capability, it will not affect the other terminal that supports interactive data channel capability from establishing a data interaction channel with the first network device.

[0155] Through the above scheme, while the terminal is making a VoIMS call, the network side actively initiates the process of establishing an interactive data channel with the terminal. In this way, the network side and the terminal can interact with each other based on the interactive data channel, transmitting data content beyond audio and video calls, expanding the capabilities of VoIMS calls and ensuring the diverse communication needs of terminal users.

[0156] The present application will now be described in further detail with reference to application examples.

[0157] Combination Figure 5 This application embodiment provides a data interaction method, including the following steps:

[0158] Steps 1-3: Terminal A and Terminal B establish a VoIMS call.

[0159] Step 4: The VoIMS application server sends a call event notification to the interactive call platform.

[0160] Step 5: Upon receiving the event notification, the interactive call platform determines that it needs to proactively initiate the creation of a data interaction channel. It then sends a call event control request to the VoIMS application server, instructing the VoIMS application server to establish an interactive data channel. Simultaneously, it carries the media negotiation information of the interactive call platform, including parameters such as channel endpoint IP, media parameters, channel substreams, and subprotocols.

[0161] Step 6: The VoIMS application server sends a re-INVITE request message to terminal A, requesting the establishment of an interactive data channel bootstrapping channel. The re-INVITE message header field adds an interactive data channel service tag, and the SDP media line adds the media sub-streams, sub-protocols supported by the interactive call platform media module, as well as the media channel endpoint IP and port number of the interactive call platform media module.

[0162] Step 7: Terminal A replies with a 200 message, responding to the re-INVITE message and indicating the interactive data channel supported by the terminal. The SDP media line of the message carries the interactive data channel media parameters supported by the terminal, including the media sub-streams, sub-protocols, terminal A's media channel endpoint IP, and port number supported by A.

[0163] Step 8: After receiving the 200 response message from terminal A, the VoIMS application server replies with an ACK confirmation response.

[0164] Step 9: The VoIMS application server sends the media negotiation results to the interactive call platform via a call event notification message.

[0165] Step 10: The interactive data channel between the media module of the interactive call platform and terminal A has been successfully established.

[0166] Step 11: The VoIMS application server initiates a re-INVITE request to terminal B, requesting the establishment of an interactive data channel bootstrapping channel. The message header field adds an interactive data channel service tag, and the SDP media line adds the media sub-streams, sub-protocols, media channel endpoint IP addresses, and port numbers supported by the interactive call platform media module.

[0167] Step 12: Terminal B replies with a 200 message, responding to the re-INVITE message and indicating the interactive data channel supported by this terminal. The SDP media line of the message carries the interactive data channel media parameters supported by the terminal, including the media sub-streams, sub-protocols, terminal A's media channel endpoint IP, and port number supported by B.

[0168] Step 13: After receiving the 200 response message from terminal B, the VoIMS application server replies with an ACK confirmation response.

[0169] Step 14: The VoIMS application server sends the media negotiation results to the interactive call platform via a call event notification message.

[0170] Step 15: The interactive data channel between the media module of the interactive call platform and terminal B has been successfully established.

[0171] It should be noted that steps 6-10 describe the VoIMS application server instructing the interactive call platform media module to establish an interactive data channel with terminal A, while steps 11-15 describe the VoIMS application server instructing the interactive call platform media module to establish an interactive data channel with terminal B. Steps 6-10 can be performed synchronously with steps 11-15.

[0172] Combination Figure 6 This application embodiment provides a data interaction method, including the following steps:

[0173] Steps 1-3: Terminal A and Terminal B establish a VoIMS call.

[0174] Step 4: The VoIMS application server sends a call event notification to the interactive call platform.

[0175] Step 5: Upon receiving the event notification, the interactive call platform determines that it needs to proactively initiate the creation of a data interaction channel. It then sends a call event control request to the VoIMS application server, instructing the VoIMS application server to establish an interactive data channel. Simultaneously, it carries the media negotiation information of the interactive call platform, including parameters such as channel endpoint IP, media parameters, channel substreams, and subprotocols.

[0176] Step 6: The VoIMS application server sends a re-INVITE request message to terminal A, requesting the establishment of an interactive data channel bootstrapping channel. The re-INVITE message header field adds an interactive data channel service tag, and the SDP media line adds the media sub-streams, sub-protocols supported by the interactive call platform media module, as well as the media channel endpoint IP and port number of the interactive call platform media module.

[0177] Step 7: Terminal A replies with a 200 message, responding to the re-INVITE message and indicating the interactive data channel supported by the terminal. The SDP media line of the message carries the interactive data channel media parameters supported by the terminal, including the media sub-streams, sub-protocols, terminal A's media channel endpoint IP, and port number supported by A.

[0178] Step 8: After receiving the 200 response message from terminal A, the VoIMS application server replies with an ACK confirmation response.

[0179] Step 9: The VoIMS application server sends the media negotiation results to the interactive call platform via a call event notification message.

[0180] Step 10: The interactive data channel between the media module of the interactive call platform and terminal A has been successfully established.

[0181] Step 11: The VoIMS application server initiates a re-INVITE request to terminal B, requesting the establishment of an interactive data channel bootstrapping channel. The message header field adds an interactive data channel service tag, and the SDP media line adds the media sub-streams, sub-protocols, media channel endpoint IP addresses, and port numbers supported by the interactive call platform media module.

[0182] Step 12: Terminal B replies with a 200 message, responding to the re-INVITE message and indicating the interactive data channel result supported by Terminal B. Here, Terminal B does not support interactive data channel capability, so the interactive data channel media parameters of the SDP media line are deleted.

[0183] Step 13: After receiving the 200 response message from terminal B, the VoIMS application server replies with an ACK confirmation response, without establishing an interactive data channel or a boot channel.

[0184] Step 14: The VoIMS server sends the result of the failure to negotiate the interactive data channel media with terminal B to the interactive call platform through a call event notification message. The media module of the interactive call platform does not establish an interactive data channel media channel with terminal B.

[0185] It should be noted that steps 6-10 describe the VoIMS application server instructing the interactive call platform media module to establish an interactive data channel with terminal A, while steps 11-15 describe the VoIMS application server instructing the interactive call platform media module to establish an interactive data channel with terminal B. Steps 6-10 can be performed synchronously with steps 11-15.
