下面对本实施例中的多媒体通话方法的实现细节进行具体的说明,以下内容仅为方便理解本方案的实现细节,并非实施本方案的必须。具体流程如图2所示,可包括如下步骤:The implementation details of the multimedia call method in this embodiment are described in detail below. The following content is only for the convenience of understanding the implementation details of the solution, and is not necessary for implementing the solution. The specific process is shown in Figure 2, and may include the following steps:
在步骤201中,接收到主叫终端发起的呼叫请求后,向5GNC-SP发送呼叫事件通知。In step 201, after receiving the call request initiated by the calling terminal, send a call event notification to the 5GNC-SP.
在一个例子中,5GNC-CP接收到主叫终端发起的呼叫请求后,5GNC-CP将用户呼叫请求通知到5GNC-SP,触发5GNC-SP根据用户信息和主叫应用的业务逻辑,判断是否需要在5GNC-MP与被叫终端之间创建一个DC通道,在5GNC-SP判断需要建立DC通道的情况下,5GNC-SP向5GNC-CP发送通道创建指示。In one example, after the 5GNC-CP receives the call request initiated by the calling terminal, the 5GNC-CP notifies the user call request to the 5GNC-SP, and triggers the 5GNC-SP to judge whether it is necessary to Create a DC channel between the 5GNC-MP and the called terminal. When the 5GNC-SP judges that a DC channel needs to be established, the 5GNC-SP sends a channel creation instruction to the 5GNC-CP.
在一个例子中,5GNC-CP接收到主叫终端发起的呼叫请求之前,主叫终端发起呼叫请求到VOLTE网络;VOLTE网络中的SBC转发呼叫请求到S-CSCF;S-CSCF根据主叫用户的签约信息,将呼叫请求转发到用户归属的5GNC-CP。In one example, before the 5GNC-CP receives the call request initiated by the calling terminal, the calling terminal initiates a call request to the VOLTE network; the SBC in the VOLTE network forwards the call request to the S-CSCF; Subscription information, and forward the call request to the 5GNC-CP to which the user belongs.
在步骤202中,接收到5GNC-SP发送的通道创建指示后,触发5GNC-MP与被叫终端建立数据通道。In step 202, after receiving the channel creation instruction sent by the 5GNC-SP, the 5GNC-MP is triggered to establish a data channel with the called terminal.
具体地说,5GNC-CP收到5GNC-SP发送的通道创建指示后,5GNC-CP指示5GNC-MP和被叫终端完成DC通道的建立。Specifically, after the 5GNC-CP receives the channel creation instruction sent by the 5GNC-SP, the 5GNC-CP instructs the 5GNC-MP and the called terminal to complete the establishment of the DC channel.
在一个例子中,5GNC-CP收到5GNC-SP发送的通道创建指示后,5GNC-CP向5GNC-MP申请DC通道的资源,接收到5GNC-MP返回的申请响应后,向被叫终端发送创建DC通道的请求,其中,所述申请响应和所述创建DC通道的请求都携带所述5GNC-MP的所述DC通道的资源信息。即5GNC-CP向5GNC-MP发送获取DC通道资源的申请,在5GNC-MP资源充足的情况下,5GNC-MP向5GNC-CP返回资源申请成功通知,并携带DC通道的资源信息;然后5GNC-CP向被叫终端申请创建DC通道并将5GNC-MP发送的DC通道的资源信息一并传输给被叫终端,供被叫终端根据DC通道的资源信息完成5GNC-MP与被叫终端之间DC通道的连接。In one example, after the 5GNC-CP receives the channel creation instruction sent by the 5GNC-SP, the 5GNC-CP applies to the 5GNC-MP for the resources of the DC channel, and after receiving the application response returned by the 5GNC-MP, sends the creation instruction to the called terminal. A request for a DC channel, wherein both the application response and the request for creating a DC channel carry resource information of the DC channel of the 5GNC-MP. That is, the 5GNC-CP sends an application for obtaining DC channel resources to the 5GNC-MP. If the 5GNC-MP resources are sufficient, the 5GNC-MP returns a resource application success notification to the 5GNC-CP, and carries the resource information of the DC channel; then the 5GNC- The CP applies to the called terminal to create a DC channel and transmits the resource information of the DC channel sent by the 5GNC-MP to the called terminal, so that the called terminal can complete the DC channel between the 5GNC-MP and the called terminal according to the resource information of the DC channel. Channel connection.
另外,5GNC-CP向5GNC中的CSCF发送所述创建DC通道的请求,所述创建DC通道的请求再经被叫终端归属的CSCF和被叫终端归属的SBC转发至所述被叫终端。In addition, the 5GNC-CP sends the request for creating a DC channel to the CSCF in the 5GNC, and the request for creating a DC channel is forwarded to the called terminal through the CSCF to which the called terminal belongs and the SBC to which the called terminal belongs.
在一个例子中,5GNC-CP发起创建DC通道的请求到5GNC中的CSCF;5GNC中的CSCF将上述创建DC通道的请求路由到被叫终端归属的CSCF;被叫侧的CSCF转发上述创建DC通道的请求到被叫侧SBC;被叫侧SBC转发创建DC通道的请求到被叫终端。In one example, the 5GNC-CP initiates a request to create a DC channel to the CSCF in the 5GNC; the CSCF in the 5GNC routes the above-mentioned request for creating a DC channel to the CSCF to which the called terminal belongs; the CSCF on the called side forwards the above-mentioned creation of a DC channel The request to the called side SBC; the called side SBC forwards the request to create a DC channel to the called terminal.
在步骤203中,数据通道创建完成后,向5GNC-SP发送数据通道创建成功通知,供5GNC-SP向5GNC-MP提供通过数据通道发送至被叫终端的内容消息。In step 203, after the data channel is created, a notification of successful data channel creation is sent to the 5GNC-SP, so that the 5GNC-SP can provide the 5GNC-MP with content information sent to the called terminal through the data channel.
在一个例子中,5GNC-MP与被叫终端之间的DC通道创建完成后,被叫终端向5GNC-CP发送创建成功响应,其中,返回响应中包含被叫终端的DC通道资源信息;5GNC-CP收到上述创建成功响应后,向5GNC-SP发送DC通道创建成功通知。In one example, after the establishment of the DC channel between the 5GNC-MP and the called terminal is completed, the called terminal sends a successful establishment response to the 5GNC-CP, wherein the returned response contains the DC channel resource information of the called terminal; 5GNC-CP After receiving the above successful creation response, the CP sends a DC channel creation success notification to the 5GNC-SP.
另外,5GNC-SP与5GNC-MP之间建立了超文本传输协议(Hyper Text Transfer Protocol,HTTP)或传输控制协议(Transmission Control Protocol,TCP)服务供两者之间进行交互,因此,在获取了5GNC-SP发送的DC通道创建成功通知后,5GNC-SP通过HTTP或TCP服务向5GNC-MP发送业务内容消息,供5GNC-MP根据DC通道向被叫终端传输业务内容信息。In addition, Hyper Text Transfer Protocol (Hyper Text Transfer Protocol, HTTP) or Transmission Control Protocol (Transmission Control Protocol, TCP) service is established between 5GNC-SP and 5GNC-MP for the interaction between the two, therefore, after obtaining After the DC channel creation notification sent by 5GNC-SP, 5GNC-SP sends a service content message to 5GNC-MP through HTTP or TCP service, for 5GNC-MP to transmit service content information to the called terminal according to the DC channel.
5GNC系统内部的交互,如5GNC-CP和5GNC-SP、5GNC-MP和5GNC-SP之间,不限定于使用HTTP消息交互,可以使用其他类型的交互方式。Interaction within the 5GNC system, such as between 5GNC-CP and 5GNC-SP, 5GNC-MP and 5GNC-SP, is not limited to using HTTP message interaction, and other types of interaction methods can be used.

The specific process is shown in Figure 3, and may include the following steps:
在步骤301中,接收5GNC-CP发送的呼叫事件通知。In step 301, a call event notification sent by the 5GNC-CP is received.
在一个例子中,在5GNC-SP接收到5GNC-CP发送的呼叫事件通知后,5GNC-SP根据主 叫用户信息和主叫业务逻辑,判断是否需要在5GNC-MP和被叫终端之间建立一个DC通道。In an example, after the 5GNC-SP receives the call event notification sent by the 5GNC-CP, the 5GNC-SP judges whether it is necessary to establish a call event between the 5GNC-MP and the called terminal based on the calling user information and the calling service logic. DC channel.
在步骤302中,在需要创建数据通道的情况下,向5GNC-CP发送通道创建指示;其中,所述数据通道为5GNC-MP与被叫终端之间的数据通道。In step 302, if a data channel needs to be created, a channel creation instruction is sent to the 5GNC-CP; wherein, the data channel is a data channel between the 5GNC-MP and the called terminal.
在一个例子中,在5GNC-SP判断出需要创建数据通道的情况下,向5GNC-CP发送通道创建指示,其中,通道创建指示中携带5GNC-SP的信息,5GNC-SP的信息中包含将创建的通道的信息,供主叫终端使用,在主叫终端通过DC通道传输内容时需要使用上述通道的信息。例如,当5GNC已经创建多个DC通道时,根据主叫终端请求功能和通道的信息,来选择对应的DC通道来进行信息内容的传输。In an example, when the 5GNC-SP determines that a data channel needs to be created, it sends a channel creation instruction to the 5GNC-CP, wherein the channel creation instruction carries 5GNC-SP information, and the 5GNC-SP information includes the information that will be created The channel information is used by the calling terminal, and the information of the above channel needs to be used when the calling terminal transmits content through the DC channel. For example, when 5GNC has created multiple DC channels, according to the calling terminal request function and channel information, select the corresponding DC channel for the transmission of information content.
在步骤303中,接收到5GNC-CP发送的数据通道创建成功通知后,向5GNC-MP提供通过数据通道发送至被叫终端的内容消息;其中,数据通道创建成功通知携带5GNC-MP和被叫终端的通道信息。In step 303, after receiving the notification of successful creation of the data channel sent by the 5GNC-CP, the content message sent to the called terminal through the data channel is provided to the 5GNC-MP; wherein, the notification of successful creation of the data channel carries the 5GNC-MP and the called terminal Terminal channel information.
在一个例子中,5GNC-SP接收到5GNC-CP发送的创建结果通知后,根据创建结果确定是否向5GNC-MP发送内容消息,供5GNC-MP通过创建的DC通道向被叫终端传输内容信息。In an example, after receiving the creation result notification sent by the 5GNC-CP, the 5GNC-SP determines whether to send the content message to the 5GNC-MP according to the creation result, so that the 5GNC-MP can transmit the content information to the called terminal through the created DC channel.
