Optionally, a 5G system or a 5G network is also called a New Radio (NR) system or an NR network.

[0037] Exemplarily, the communication system to which the embodiments of the present disclosure are applied includes a network device and a terminal device (also called a terminal or a communication terminal). The network device is a device that communicates with the terminal device. Here, the network device can provide a communication overlay within a certain area range and communicate with terminals located within that area. Optionally, the network device is a base station in each communication system, for example, an Evolutional Node B (eNB) in an LTE system, and also, for example, a base station (gNB) in a 5G system or an NR system.

[0038] In the network / system in the embodiments of the present disclosure, a device having a communication function is referred to as a communication device. The communication device includes a network device and a terminal having a communication function. The network device and the terminal are the specific devices described above and will not be described here. The communication device may also include other devices in the communication system, such as other network entities such as a network controller and a mobility management entity, but in the embodiments of the present disclosure, it is not limited thereto.

[0039] Note that in this specification, the terms "system" and "network" are often used interchangeably. In this specification, the term "and / or" simply describes the relationship of related objects and means that three relationships can exist. For example, A and / or B represents three cases where A exists alone, A and B exist simultaneously, and B exists alone. Also, in this specification, the character " / " generally indicates that the related objects before and after are in an "or" relationship.

[0040] The terms "first", "second", etc. in the specification and claims of the present disclosure are not used to describe a specific order or sequence, but are used to distinguish similar objects. Note that the data used in this way is appropriately exchanged so that the embodiments of the present disclosure described in this specification can be implemented in an order other than, for example, those illustrated or described in this specification. Furthermore, the terms "include" and "have" and any variations thereof are intended to be non-exclusive. For example, a process, method, system, product, or apparatus including a series of steps or units is not necessarily limited to those steps or units clearly listed, and may include other steps or units not clearly listed or other steps or units specific to those processes, methods, products, or apparatuses.

[0041] In an embodiment of the present disclosure, a service realization method applied to a first network device is provided. FIG. 1 is a schematic flowchart 1 of the service realization method according to an embodiment of the present disclosure. As shown in FIG. 1, the method includes step 101 in which a first network device negotiates with a first terminal for DC and establishes a first DC based on the DC negotiation process. The first DC is used to transmit interaction data between the first terminal and a second network device.

[0042] In this embodiment, the first network device is a network device having at least a DC negotiation function.

In other embodiments, the first network device is jointly realized by a Voice over New Radio (VoNR)+ platform, a new call platform (or an internal system platform), etc.

[0044] In some selectable embodiments, for the first network device to perform DC negotiation with the first terminal includes the first network device sending a first request for DC negotiation including at least DC parameters to the first terminal, and the first network device receiving a first response corresponding to the first request sent from the first terminal.

[0045] In this embodiment, for the first network device to perform DC negotiation with the first terminal specifically includes sending a first request carrying at least DC negotiation parameters of the negotiation to the first terminal, and when the first terminal receives the first request, the first terminal sends a first response indicating agreement or support for the DC negotiation parameters of the negotiation to the first network device, thereby establishing a first DC based on the DC negotiation parameters. Optionally, the DC negotiation parameters are included in the first response.

[0046] Optionally, the method further includes the first network device associating the first DC with the second network device based on label information in the DC negotiation parameters.

[0047] In some alternative embodiments of the present disclosure, for the first network device to perform DC negotiation with the first terminal may include the first network device performing DC negotiation with the first terminal between the first terminal and the second network device, or the first network device performing DC negotiation with the first terminal between the first terminal and the third network device.

[0048] Exemplarily, the second network device is specifically a ringtone platform or a ringtone system. Here, the ringtone platform or the ringtone system is at least used for processing ringtone services, for example, for negotiating media resources of ringtones. Optionally, the second network device in the embodiments of the present disclosure is a service system for, in addition to processing ringtone services, managing the first DC, managing audio and video channels, and processing interaction data in the embodiments of the present disclosure. In other embodiments, the second network device may be another platform, system or device for processing services (which may be other services other than ringtones during a call).

[0049] In this embodiment, as shown in FIG. 2a, the first DC is a DC between the first terminal and the second network device. In this case, interaction data can be transmitted between the first terminal and the second network device via the first DC. Alternatively, as shown in FIG. 2b, the first DC is a DC between the first terminal and the third network device. In this case, the first network device and the first terminal negotiate a DC between the first terminal and the second network device, or a DC between the first terminal and the third network device.

[0050] In this embodiment, the third network device may be the same network device as the first network device, or the third network device may be a different network device from the first network device. Exemplarily, the first DC between the first terminal and the third network device is the DC between the first terminal and the media module. The media module is used to transfer and process data within the first DC. Here, the media module may be a module within the first network device. In this case, the third network device is the same as the first network device. Or, the media module may be arranged independently. In this case, the third network device is a different network device from the first network device.

[0051] Exemplarily, the third network device may be a DC server (Data Channel Server), a DC management platform, a new call platform, a session border controller (Session Border Controller: SBC), etc., or may be implemented by a VoNR+ media server.

[0052] In this embodiment, optionally, the first network device receives a subscription from the second network device and performs DC negotiation with the first terminal based on the subscription.

[0053] In some selectable embodiments, the method further includes the first network device receiving first information used to subscribe to a call event transmitted from the second network device, and when the first network device receives a call event, the first network device transmits the call event to the second network device and receives a first message transmitted from the second network device and used to instruct the first network device to perform DC negotiation. Correspondingly, the first network device performing DC negotiation with the first terminal includes the first network device triggering the DC negotiation with the first terminal according to the first message.

[0054] In this embodiment, the second network device transmits first information for subscribing to a call event to the first network device. Based on the subscription of the call event, when the first network device receives a call event (such as an incoming ringing message), the first network device transmits the call event to the second network device to notify the second network device of the call event. The second network device transmits a first message used to instruct the first network device to perform DC negotiation to the first network device. The first network device performs DC negotiation with the first terminal according to the instruction of the first message.

[0055] In another selectable embodiment, the first network device itself acquires call control capabilities in advance, and when receiving a call event (such as an incoming ringing message), triggers DC negotiation with the first terminal based on the call control capabilities.

[0056] In each embodiment of the present disclosure, the interaction data is any data related to an interaction function and / or an interaction ability. As some examples, a first terminal displays an interaction interface by an application. The interaction data is data generated based on an operation (which may be referred to as an interaction operation) detected by the first terminal when a user operates through the interaction interface. In this case, the interaction data is the interaction data transmitted from the first terminal to a second network device. As another example, the interaction data may be the interaction data transmitted from the second network device to the first terminal. For example, after the first terminal transmits interaction data to the second network device, the second network device transmits content corresponding to or related to the interaction data to the first terminal. The data corresponding to the content is referred to as the interaction data transmitted from the second network device to the first terminal.

[0057] Based on the above embodiments, in an embodiment of the present disclosure, a service realization method applied to a first terminal is further provided. FIG. 3 is a schematic flowchart 2 of the service realization method according to an embodiment of the present disclosure. As shown in FIG. 3, the method includes: step 201 in which the first terminal performs DC negotiation with a first network device and establishes a first DC through the DC negotiation; and step 202 in which the first terminal transmits interaction data with a second network device based on at least the first DC.

[0058] In some selectable embodiments, the first terminal performing DC negotiation with the first network device includes: the first terminal receiving a first request for DC negotiation transmitted from the first network device and including at least DC negotiation parameters; and the first terminal transmitting a first response corresponding to the first request to the first network device.

[0059] In this embodiment, for the first terminal to perform DC negotiation with the first network device, specifically, it receives a first request for DC negotiation sent from the first network device, that is, the DC negotiation is initiated by the first network device. When the first terminal receives the first request, it sends a first response indicating agreement or support for the DC negotiation parameters to the first network device. Optionally, the DC negotiation parameters are included in the first response.

[0060] In some selectable embodiments, for the first terminal to perform DC negotiation with the first network device includes the first terminal performing DC negotiation between the first terminal and the second network device with the first network device, or the first terminal performing DC negotiation between the first terminal and the third network device with the first network device.

[0061] In this embodiment, as shown in FIG. 2a, the first DC is the DC between the first terminal and the second network device. In this case, interaction data can be transmitted between the first terminal and the second network device via the first DC. Or, as shown in FIG. 2b, the first DC is the DC between the first terminal and the third network device. In this case, the first network device and the first terminal negotiate the DC between the first terminal and the second network device, or the DC between the first terminal and the third network device.

[0062] In this embodiment, the third network device may be the same network device as the first network device, or the third network device may be a different network device from the first network device. Exemplarily, the first DC between the first terminal and the third network device may be the DC between the first terminal and the media module. The media module is used to transfer and process data within the first DC. Here, the media module may be a module within the first network device. In this case, the third network device is the same as the first network device. Or, the media module may be arranged independently. In this case, the third network device is a different network device from the first network device.

[0063] In some selectable embodiments, transmitting interaction data to the second network device based on at least the first DC includes the first terminal transmitting interaction data to the second network device via the first DC, or the first terminal transmitting, via the first DC, the interaction data transferred to the second network device via the third network device to the third network device, or the first terminal receiving, via the first DC, the interaction data from the second network device transmitted from the third network device.

[0064] In this embodiment, in one example, when negotiating a DC between the first terminal and the second network device, the first DC is the DC between the first terminal and the second network device, as shown in FIG. 2a. In this case, interaction data between the first terminal and the second network device can be directly transmitted via the first DC. In another example, when negotiating a DC between the first terminal and the third network device, the first DC is the DC between the first terminal and the third network device. In that case, the transmission between the first terminal and the second network device is divided into two parts. The transmission between the first terminal and the third network device is via the first DC, while the transmission between the third network device and the second network device is realized by data transfer, as shown in FIG. 2b.

[0065] In some alternative embodiments of the present disclosure, the method further includes the first terminal establishing a second DC with a third network device and obtaining a first application via the second DC.

[0066] In this embodiment, the third network device has a function of managing DC applications. Optionally, the third network device may be the same network device as the first network device or a different network device from the first network device.

[0067] In this embodiment, a second DC is established between the first terminal and the third network device, and the second DC is, for example, a bootstrap DC. Based on the second DC, the first terminal acquires a first application from the third network device. The first application is an application related to or associated with the incoming call sound service. For example, the first application is an incoming call sound application, that is, the first terminal downloads the incoming call sound application from the third network device based on the second DC. In other embodiments, the first application may be other applications, for example, an application in Hyper Text Markup Language (HTML) format. The first terminal can use a browser as the first application.

[0068] In some selectable embodiments, the method further includes the first terminal presenting an interaction interface by the first application and / or interaction data in the first DC.

[0069] In this embodiment, the first terminal presents an interaction interface by triggering or launching the first application. Through the interaction interface, content related to the incoming call sound service (or content corresponding to the interaction data) can be displayed. And / or, the first terminal presents an interaction interface by the interaction data transmitted in the first DC. That is, the content of the interaction data transmitted in the first DC is output and displayed through the interaction interface output.

[0070] In some selectable embodiments, the method further includes the first terminal associating the first DC with the first application.

[0071] In this embodiment, the first terminal associates a first DC with the first application, and displays, via an interaction interface of the first application, interaction data transmitted via the first DC. Exemplarily, the first terminal establishes an association relationship between the first DC and the first application (or an identifier of the first application) by associating an identifier of the first DC with the first application (or an identifier of the first application), thereby associating the first DC with the first application.

[0072] In some alternative embodiments, the method further includes the first terminal causing the first application to display the interaction data based on the association relationship between the first DC and the first application.

[0073] In this embodiment, the first terminal receives interaction data transmitted via the first DC, and based on the association relationship between the first DC and the first application, displays the interaction data via an interaction interface of the first application. For example, after receiving a call event (or a ringing message, 180 message), the first terminal interacts with a second network device (e.g., transmits interaction data at least via the first DC), thereby displaying the content of the interaction data via an interaction interface of the first application.

[0074] In some alternative embodiments of the present disclosure, the method further includes the first terminal negotiating media resources with the second network device, and establishing, by the media resource negotiation, a first channel and / or a second channel for audio data and / or video data transmission between the first terminal and the second network device.

[0075] In this embodiment, media resource negotiation is performed between the first terminal and the second network device, and the media resources to be negotiated are audio and / or video resources related to the incoming call service. In some selectable embodiments, the first channel is a channel for transmitting audio data and is also called an audio channel. The second channel is a channel for transmitting video data and is also called a video channel. In another selectable embodiment, the first channel is a channel for transmitting audio data and video data, and / or the second channel is a channel for transmitting audio data and video data. By establishing the first channel and / or the second channel, the first terminal receives media data (such as incoming call data, which is audio data and / or video data) from the second network device. Therefore, when a call event (such as a ringing message) is received, the incoming call service is realized by outputting or playing the media data.

[0076] Based on the above-described embodiments, in an embodiment of the present disclosure, a service realization method is further provided. FIG. 4 is a schematic flowchart 3 of the service realization method according to an embodiment of the present disclosure. As shown in FIG. 4, the method includes step 301 in which the second network device transmits interaction data to the first terminal based on at least a first DC. The first DC is established by DC negotiation between the first terminal and the first network device.

[0077] In this embodiment, a first DC is established in advance before the interaction data transmission between the second network device and the first terminal. Between the second network device and the first DC, interaction data is transmitted at least via the first DC.

In this case, interaction data can be transmitted between the first terminal and the second network device via the first DC. Or, as shown in FIG. 2b, the first DC is a DC between the first terminal and the third network device. In this case, the first network device and the first terminal negotiate a DC between the first terminal and the second network device or a DC between the first terminal and the third network device.

[0081] In this embodiment, the third network device may be the same network device as the first network device, or the third network device may be a different network device from the first network device. Exemplarily, the first DC between the first terminal and the third network device may be the DC between the first terminal and the media module. The media module is used to transfer and process data within the first DC. Here, the media module may be a module within the first network device. In this case, the third network device is the same as the first network device. Or, the media module may be arranged independently. In this case, the third network device is a different network device from the first network device.

[0082] In some selectable embodiments of the present disclosure, the method further includes the second network device performing media resource negotiation with the first terminal, and establishing a first channel and / or a second channel for audio and / or video data transmission between the first terminal and the second network device through the media resource negotiation.

In some alternative embodiments, the first channel is a channel for transmitting audio data and is also referred to as an audio channel. The second channel is a channel for transmitting video data and is also referred to as a video channel. In another alternative embodiment, the first channel is a channel for transmitting audio data and video data, and / or the second channel is a channel for transmitting audio data and video data. By establishing the first channel and / or the second channel, the first terminal receives media data (such as incoming call data, which is audio data and / or video data) from the second network device. Therefore, when a call event (such as a ringing message) is received, the incoming call service is realized by outputting or playing the media data.

[0084] In some alternative embodiments, the second network device performing media resource negotiation with the first terminal includes starting media resource negotiation with the first terminal when the second network device receives a call event.

[0085] In this embodiment, after receiving a call event, the second network device sends a first message for media resource negotiation to the first terminal. The message includes media resource negotiation parameters. The media resource negotiation parameters are used for establishing the first channel and / or the second channel. Optionally, the first terminal sends a second message to the second network device indicating that the terminal supports or agrees to the media resource negotiation parameters. Optionally, the second message also includes the media resource negotiation parameters.

[0086] In some selectable embodiments, the method further includes the second network device managing at least one of the first DC, the first channel, and the second channel.

[0089] In this embodiment, the interaction data transmitted via the first DC is interaction data related to the content transmitted on the first channel and / or the second channel, that is, interaction data related to the content of audio data and / or video data. For example, when the data transmitted via the first channel and / or the second channel is video content, the interaction data is data on the user's preference for the video content, such as "like" data. Also, for example, when the data transmitted via the first channel and / or the second channel is a variety show, the interaction data is the user's voting data for the variety show.

[0090] In some alternative embodiments of the present disclosure, the method includes the second network device sending first information used to subscribe to call events to the first network device.

[0091] In this embodiment, the second network device subscribes to call events with respect to the first network device, and based on the subscription, triggers DC negotiation with the first terminal.

[0092] In some alternative embodiments, the method includes the second network device receiving a call event sent from the first network device, and the second network device sending a first message used to instruct the first network device to negotiate a DC channel to the first network device.

[0093] In this embodiment, the second network device sends first information for subscribing to call events to the first network device. Based on the subscription to call events, when the first network device receives a call event (for example, an incoming ringing message), the first network device sends the call event to the second network device to notify the second network device of the call event. The second network device sends a first message for instructing the first network device to perform DC negotiation to the first network device. The first network device performs DC negotiation with the first terminal based on the instruction of the first message.

[0094] According to the technical means of the embodiments of the present disclosure, a reliable and efficient DC negotiation is proposed, and interaction data between a terminal and a second network device is transmitted via a DC (the first DC) established by the negotiation. Therefore, by transmitting the interaction data via the newly established first DC by the negotiation, collisions between media negotiation and DC negotiation are avoided, and collisions between media data transmission and interaction data transmission are also avoided. Moreover, by transmitting the interaction data via the first DC, a richer interaction function can be realized, and the user operation experience can be significantly improved. The present disclosure is applicable not only to the interaction scenario of the incoming call service, but also to other service interaction scenarios during a call. For example, during a call, interaction data is presented via the interaction interface of the first application. The user can obtain richer content via the presentation of the interaction interface, and can also perform an input operation via the input device of the first terminal. Thereby, the first terminal can acquire the user's interaction data, and transmit the interaction data via the above-mentioned first DC, realizing a richer and more complex interaction operation, and significantly improving the user operation experience.

[0095] Hereinafter, the service realization method of the embodiments of the present disclosure will be described with reference to specific examples.

[0096] In each of the following examples, the first network device is described as an IMS network element, and the second network device is described as an incoming call tone platform.

[0097] Example 1: FIG. 5 is a schematic diagram of an interaction flow 1 of the service realization method of the embodiments of the present disclosure. As shown in FIG. 5, the method includes the following. Steps 401 - 402: UEa sends a call request containing audio - video media parameters (a, v) and a DC capability label to an IMS network element. The IMS network element sends the call request containing audio - video media parameters a, v and the DC capability label to an Interrogating / Serving Call Session Control Function (I / S - CSCF). Here, a represents audio media parameters, v represents video media parameters, and a and v are used for negotiation of audio - video channels. The above - mentioned DC capability label represents the DC capability of UEa, such as whether UEa supports DC capability. In this example, the IMS network element includes a VOLTE AS and a VoNR + platform, that is, it is jointly realized by the VOLTE AS and the VoNR + platform (or an internal system platform). Step 403: The I / S - CSCF sends the call request containing audio - video media parameters a, v and the DC capability label to UEb. Step 404: Continue to complete the initial media negotiation (or initial media resource negotiation for initial audio - video channel negotiation) between UEa and UEb. Steps 405 - 406: UEb sends a 180 - message to the I / S - CSCF, and the I / S - CSCF sends the 180 - message to the IMS network element. Step 407: Call event notification and call control. This step is optional. Here, the incoming call tone platform subscribes to call events from the IMS network element. When the IMS network element detects a call event, it sends the call event to the incoming call tone platform. The incoming call tone platform sends a first message to the IMS network element for instructing the negotiation of the DC channel with the IMS network element. The IMS network element triggers the DC negotiation with the UE according to the first message, that is, triggers the execution of subsequent steps 408 to 409. In other embodiments, the IMS network element has call control capabilities. When the IMS network element detects a call event, it triggers the DC negotiation with the first terminal based on the call control capabilities. Steps 408 to 409: The IMS network element sends an update message to UEa, and UEa sends a 200 update message to the IMS network element. Here, steps 408 and 409 complete the DC negotiation process between UEa and the IMS network element. Step 410: Complete the negotiation of the Datagram Transport Layer Security (DTLS) protocol and the Stream Control Transmission Protocol (SCTP) link between UEa and UEb. Step 411: The IMS network element sends a 180 message to the incoming call tone platform. Here, step 410 can be executed in parallel with the 180 message in step 411. Steps 412 to 413: The incoming call tone platform sends an update message carrying the incoming call tone audio / video media resource parameters to UEa. UEa sends a 200 update message to the incoming call tone platform. Steps 414 - 415: UEa sends an update message to the incoming call tone platform, and the incoming call tone platform sends 200 update messages to UEa. Here, if resource reservation is completed in the media negotiation process of steps 412 - 413, steps 414 - 415 are not executed. If resource reservation is not completed in the media negotiation process of steps 412 - 413, steps 414 - 415 are used to continue the media negotiation process to complete resource reservation. Steps 416 - 417: The incoming call tone platform plays the incoming call tone and sends a 180 message to UEa. Step 418: Interaction data is transmitted between UEa and the incoming call tone platform. Specifically, there are the following two forms. Step 418a: Interaction data is directly transmitted between UEa and the incoming call tone platform via the established DC. Step 418b: UEa transmits interaction data to an IMS network element via the DC, and the transfer function of the IMS network element transmits the interaction data to the incoming call tone platform. Here, the DC is the first DC in the above embodiment. Step 419: UEb goes off - hook. Steps 420 - 422: UEb sends a 200 OK message to the I / S - CSCF, the I / S - CSCF sends a 200 OK message to the incoming call tone platform, and the incoming call tone platform stops playing the incoming call tone. Step 423: The incoming call tone platform triggers the completion of media renegotiation. Step 424: A call is established between UEa and UEb.

[0098] Example 2: Figure 6 is a schematic diagram of the interaction flow 2 of the service realization method according to an embodiment of the present disclosure. As shown in Figure 6, the method includes the following. Steps 501 to 502: UEa sends a call request including audio / video media parameters, bootstrap DC media parameters, and a DC capability label to an IMS network element. The IMS network element sends a call request including audio / video media parameters, bootstrap DC media parameters, and a DC capability label to I / S-CSCF. The DC capability label represents the DC capability of UEa, such as whether UEa supports DC capability. In this example, the IMS network element includes a VOLTE AS and a VoNR+ platform, that is, it is jointly realized by the VOLTE AS and the VoNR+ platform (or an internal system platform). Step 503: I / S-CSCF sends a call request including audio / video media parameters a, v and a DC capability label to UEb. Step 504: Continue to complete the initial media negotiation (or initial media resource negotiation for initial audio / video channel negotiation) between UEa and UEb. Step 505: Complete the establishment of bootstrap DC between UEa and the IMS network element. Steps 506 to 507: UEa requests an incoming call DC application from the IMS network element via bootstrap DC. The IMS network element sends an incoming call DC application to UEa via bootstrap DC. Thus, the download of the incoming call DC application by UEa is realized. Here, steps 505 to 507 can be executed in parallel with step 504 without limiting the order. Step 508 - Step 509: UEb sends a 180 message to the I / S-CSCF, and the I / S-CSCF sends the 180 message to the IMS network element. Step 510: Call event notification and call control. This step is optional. Here, the incoming call tone platform subscribes to call events from the IMS network element. When the IMS network element detects a call event, it sends the call event to the incoming call tone platform. The incoming call tone platform sends a first message used to instruct the IMS network element to negotiate the DC channel to the IMS network element. The IMS network element triggers the DC negotiation with the UE based on the first message, that is, triggers the execution of subsequent steps 511 - 512. In other embodiments, the IMS network element has call control capabilities. When the IMS network element detects a call event, it triggers the DC negotiation with the first terminal based on the call control capabilities. Steps 511 - 512: The IMS network element sends an update message to UEa, and UEa sends a 200 update message to the IMS network element. Here, steps 511 and 512 complete the DC negotiation process between UEa and the IMS network element. Step 513: Complete the DC channel DTLS and SCTP link establishment negotiation between UEa and UEb. Step 514: The IMS network element sends a 180 message to the incoming call tone platform. Here, step 513 can be executed in parallel with the 180 message in step 514. Steps 515 - 516: The incoming call tone platform sends an update message carrying the incoming call tone audio / video media resource parameters to UEa. UEa sends a 200 update message to the incoming call tone platform. Steps 517 - 518: UEa sends an update message to the incoming call tone platform, and the incoming call tone platform sends a 200 update message to UEa. Here, if resource reservation is completed in the media negotiation process of steps 515 - 516, steps 517 - 518 are not executed. If resource reservation is not completed in the media negotiation process from step 515 to step 516, the media negotiation process is continued from steps 517 to 518 to complete resource reservation. Steps 519 - 520: The incoming call tone platform plays the incoming call tone and sends a 180 message to UEA. Step 521: Interaction data is transmitted between UEa and the incoming call tone platform. Specifically, there are the following two forms. Step 521a: Interaction data is directly transmitted between UEa and the incoming call tone platform via the established DC. Step 521b: UEa transmits interaction data to the IMS network element via the DC, and the transfer function of the IMS network element transmits the interaction data to the incoming call tone platform. Here, the DC is the first DC in the above embodiment. Step 522: When UEa receives a 180 message, based on the incoming call tone DC application instruction, UEa combines the incoming call tone DC interaction data to perform interface presentation and provide an interaction function. Step 523: UEb goes off - hook. Steps 524 - 526: UEb sends a 200 OK message to the I / S - CSCF, the I / S - CSCF sends a 200 OK message to the incoming call tone platform, and the incoming call tone platform stops playing the incoming call tone. Step 527: The incoming call tone platform triggers the completion of media re - negotiation. Step 528: A call is established between UEa and UEb.
