技术领域
本申请涉及通信技术领域，尤其涉及一种多媒体通话方法、装置、电子设备及存储介质。
背景技术
随着通信技术的发展，来电系统不再局限于只显示呼叫方的电话号码，而是增加了很多个性化的内容信息。目前广为使用的多媒体来电，呼叫方提前上传通话前本人希望展示的内容信息，包括音频、文字、图像。当呼叫时，接听方手机在振铃的同时会显示这些来自于呼叫方的信息，显示形式包括彩印、彩像等等，以便更好地了解到呼叫方的通话意图。
然而，目前广为使用的多媒体来电，包括彩印、彩像，主要包含一些简单的音频、文字、图片信息，形式简单，内容不够丰富。另外，在交互性上也有所欠缺，接听方只能被动接受信息，无法主动获取希望了解的资讯，并且传送内容所使用的是通话通道，与通话本身的业务逻辑耦合性较高，不利于来电业务的扩展。因此，常用的多媒体来电系统中，具有内容不够丰富、交互性较差、安全性能较低以及来电业务不易扩展的问题。

具体实施方式
为使本申请实施例的目的、技术方案和优点更加清楚，下面将结合附图对本申请的各实施方式进行详细的阐述。然而，本领域的普通技术人员可以理解，在本申请各实施方式中，为了使读者更好地理解本申请而提出了许多技术细节。但是，即使没有这些技术细节和基于以下各实施方式的种种变化和修改，也可以实现本申请所要求保护的技术方案。
本申请的实施例涉及一种多媒体通话方法，应用于5GNC-CP，方法包括：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；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；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。实现了在多媒体通话过程中，能传输更具有多样性和交互性的内容信息，同时也保证了内容信息的安全，提高了用户体验。
在本申请实施例中，5GNC系统中的用户手机终端在逻辑功能层面分为长期演进语音承载(Voice over Long-Term Evolution,VOLTE)客户端和数据通道(Data Channel,DC)客户端。
VOLTE客户端，用于通话和传输呼叫过程中的通信控制信令，如应答或挂断等控制；DC客户端用于通话外内容的传输，包括DC通道的建立、附加内容的获取和解析等。VOLTE客户端和DC客户端在逻辑上互相独立，DC通道独立于呼叫通道，在用户通话前，通过会话发起协议(Session initialization Protocol,SIP)消息协商，来完成DC通道(为了方便理解，后文中数据通道统一称为DC通道)的建立。
在本申请实施例中，5GNC系统的网络架构如图1所示，其中，5GNC系统由以下网元组成：
通话处理模块(Call Platform，CP)，用于提供事件上报、呼叫控制、放音收号、视频播放以及会议控制等功能。
应用服务器(Service Platform，SP)，用于与CP对接，提供5G新通话特定服务以及实现呼叫控制等功能。同时，支持从用户数据中心获取用户或企业的信息。
媒体平台(Media Platform，MP)，用于与CP对接、与用户对接，提供媒体通道的建立以及媒体控制等功能。
用户数据中心(Service Center，SC)，负责为新通话业务提供统一的业务数据存储服务，实现各种业务服务之间的数据共享。
管理平台(Portal Platform，PP)用于为用户或商家提供5GNC业务的素材管理功能，实现素材的上传、修改以及审核等。
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：
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。
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。
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。
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。
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。
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。
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。
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。
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。
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。
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。
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。
本申请实施例提供的多媒体通话方法，通过将5G网络和DC通道结合，使用DC通道在5G网络中传输内容信息，实现了更灵活多变的业务，采用DC通道传输内容信息，可以实现业务内容具有多样性和交互性，并且由于DC通道自身具有服务质量(Quality of Service，QoS),能更好的防止内容信息外泄和被侵入，保证了内容信息的安全性，另外，单独的使用DC通道进行内容传输，不占用通话通道的资源，减少了通话通道的负担，同时保证了通话质量和内容传输质量，提高了用户的体验感。
本申请实施例还涉及一种多媒体通话方法，应用于5GNC-SP，包括：接收5GNC-CP发送的呼叫事件通知；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，数据通道为5GNC-MP与被叫终端之间的数据通道；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。
下面对本申请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3所示，可包括如下步骤：
在步骤301中，接收5GNC-CP发送的呼叫事件通知。
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。
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。
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。
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。
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。
另外，内容消息包括：主叫业务的所有内容或主叫业务所在统一资源定位系统(uniform resource locator，URL)。
在一个例子中，在传输的内容消息为业务的所有内容时，被叫终端收到内容消息后，解析上述内容消息即可在终端上进行显示。
在一个例子中，在传输的内容消息为主叫业务所在URL时，被叫终端获取内容消息后，通过发送HTTP GET到主叫用户的5GNC来获取业务内容。
另外，如果下发的内容消息支持可交互的内容，如动态页面等，被叫终端可以根据被叫用户指示发送HTTP POST消息到5GNC，得到目标内容信息。
本申请实施例提供的媒体通话方法，通过在用户终端和服务器之间建立一个专门用于传输内容信息的DC通道，使得传输的内容更具多样性，在内容具有交互性的情况下，用户可以感受交互通话体验，被叫终端可以自主选择是否要获取主叫终端提供的内容信息，同时也可以自主选择获取哪些内容信息作为目标信息，解决了接听方只能被动接受信息，无法主动获取希望了解的资源的问题，提高了用户体验。
为了使本申请实施例提供的多媒体通话方法的具体实现过程更加简明，提供了一个多媒体通话方法的交互流程，具体交互流程参考图4所示，具体步骤如下：
在一个例子中，多媒体通话方法主要涉及主叫名片业务场景。
在步骤401中，主叫用户发起呼叫，终端向VOLTE网络发起呼叫请求。
在步骤402中，主叫侧SBC向CSCF转发呼叫请求。
在步骤403中，CSCF根据主叫用户的签约信息，将呼叫请求触发到主叫用户归属的5GNC中的CP,即5GNC-CP。
在步骤404中，5GNC-CP通过HTTP请求发送呼叫事件通知到5GNC-SP。
在步骤405中，5GNC-SP根据主叫用户信息和主叫名片业务逻辑，向5GNC-CP发起创建5GNC-MP和被叫终端之间的DC通道的指示，其中，创建指示中携带5GNC-SP的信息。
在步骤406中，5GNC-CP向5GNC-MP申请DC通道资源。
在步骤407中，5GNC-CP发起创建DC通道的请求到5GNC中的CSCF。
在步骤408中，5GNC中的CSCF将创建DC通道的请求路由到被叫侧的CSCF。
在步骤409中，被叫侧CSCF转发创建DC通道的请求到被叫侧SBC。
在步骤410中，被叫侧SBC转发创建DC通道的请求到被叫终端。
在步骤411中，5GNC-CP通过HTTP请求发送DC通道创建成功通知到5GNC-SP。
在一个例子中，本申请实施例中媒体通话方法的具体信令流程参考图5所示，具体步骤如下：
在步骤501中，5GNC-CP接收到主叫终端A的呼叫请求后，向5GNC-SP发送呼叫通知。
在步骤502中，5GNC-SP根据用户信息和主叫名片的业务逻辑，认为需要创建到被叫终端的DC通道，则请求5GNC-CP进行DC通道创建。
在步骤503中，5GNC-CP发送DC通道创建指示到5GNC-MP，申请DC通道资源，其中，创建指示中不携带会话描述协议(Session Description Protocol，SDP)信息。
在步骤504中，5GNC-MP返回200OK响应，其中的SDP answer包含5GNC-MP的DC通道资源信息。
在步骤505中，5GNC-CP发送创建请求到5GNC-IMS，其中的SDP携带了5GNC-MP的DC通道资源信息。
在步骤506中，5GNC-IMS转发创建请求到被叫终端所在IMS网络，然后再转发到被叫终端B。
在步骤507中，被叫终端B返回200OK响应，其中的SDP answer包含终端B的DC通道资源信息。
在步骤508中，5GNC-CP向5GNC-SP发送DC通道创建结果通知，其中包含5GNC-MP和被叫终端B的DC通道信息。
另外，完成5GNC-MP和被叫终端的DC通道创建后，5GNC进行名片下发指示，发送HTTP POST消息到终端，其中，上述操作有两种下发方式。
在一个例子中，HTTP POST消息直接包含名片的所有内容，终端接收HTTP POST消息后，解析出名片的所有内容并在终端上进行展示。
在一个例子中，HTTP POST消息中只携带名片所在URL，由终端收到HTTP POST消息后，向5GNC发送HTTP GET消息来获取名片内容。
本申请实施例提供的媒体通话方法，不局限于运用在电子名片的显示上，也可以用于其他业务场景，传输其他内容。并且在通话结束后，DC通道仍可保持不切断，后续可以继续使用该通道传输其他内容信息。
在本申请实施例中，通过创建DC通道来传输各类内容信息，避免了通过通话通道传递内容而导致来电业务不易扩展的问题，另外，数据通道具有轻量化、快速上线、灵活以及可控等特点，使得可以实现更灵活多变的业务，并且采用数据通道传输内容信息，能提供交互功能，可以保证内容更多样化，不占用通话通道的资源。通道自身具备的QoS还保证了内容信息的安全性，使得用户体验得到了提升。
上面各种方法的步骤划分，只是为了描述清楚，实现时可以合并为一个步骤或者对某些步骤进行拆分，分解为多个步骤，只要包括相同的逻辑关系，都在本专利的保护范围内；对算法中或者流程中添加无关紧要的修改或者引入无关紧要的设计，但不改变其算法和流程的核心设计都在该专利的保护范围内。
本申请实施例还涉及一种多媒体通话装置，应用于5GNC-CP，如图6所示，包括：事件通知发送模块601、触发模块602以及通知发送模块603。
具体地说，事件通知发送模块601：用于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；触发模块602：用于接收到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；通知发送模块603：用于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。
在一个例子中，事件通知发送模块601接收到主叫终端发起的呼叫请求后，事件通知发送模块601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。
在一个例子中，收到5GNC-SP发送的通道创建指示后，触发模块602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。
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，通知发送模块603向5GNC-SP发送DC通道创建成功通知。
本申请实施例提供的多媒体通话装置，通过将5G网络和DC通道结合，使用DC通道在5G网络中传输内容信息，实现了更灵活多变的业务，同时采用DC通道传输内容信息，可以使业务内容具有多样性和交互性，并且由于DC通道自身具有QoS，能更好的防止内容信息外泄和被侵入，保证了内容信息的安全性，另外，单独的使用DC通道进行内容传输，不占用通话通道的资源，减少了通话通道的负担，同时保证了通话质量和内容传输质量，提高了用户的体验感。
不难发现，本实施方式为上述应用于5GNC-CP多媒体通话方法实施例相对应的装置实施例，本实施方式可与上述应用于5GNC-CP多媒体通话方法实施例互相配合实施。上述应用于5GNC-CP多媒体通话方法实施例提到的相关技术细节在本实施方式中依然有效，为了减少重复，这里不再赘述。相应地，本实施方式中提到的相关技术细节也可应用在上述应用于5GNC-CP多媒体通话方法实施例中。
本申请实施例还涉及一种多媒体通话装置，应用于5GNC-SP，如图7所示，包括：事件通知接收模块701、指示发送模块702以及通知接收模块703。
具体地说，事件通知接收模块701：用于接收5GNC-CP发送的呼叫事件通知；指示发送模块702：用于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，数据通道为5GNC-MP与被叫终端之间的数据通道；通知接收模块703：用于接收到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。
在一个例子中，在事件通知接收模块701接收到5GNC-CP发送的呼叫事件通知后，事件通知接收模块701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。
在一个例子中，通知接收模块703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，另外，内容消息包括：主叫业务的所有内容或主叫业务所在URL。
在一个例子中，在传输的内容消息为业务的所有内容时，被叫终端收到内容消息后，解析上述内容消息即可在终端上进行显示；在传输的内容消息为主叫业务所在URL时，被叫终端获取内容消息后，通过发送HTTP GET到主叫用户的5GNC来获取业务内容。
另外，如果下发的内容消息支持可交互的内容，如动态页面等，被叫终端可以根据被叫用户指示发送HTTP POST消息到5GNC，得到目标内容信息。
本申请实施例提供的媒体通话装置，通过在用户终端和服务器之间建立一个专门用于传输内容信息的DC通道，使得传输的内容更具多样性，在内容具有交互性的情况下，用户可以感受交互通话体验，被叫终端可以自主选择是否要获取主叫终端提供的内容信息，同时也可以自主选择获取哪些内容信息作为目标信息，解决了接听方只能被动接受信息，无法主动获取希望了解的资源的问题，提高了用户体验。

值得一提的是，本申请上述实施方式中所涉及到的各模块均为逻辑模块，在实际应用中，一个逻辑单元可以是一个物理单元，也可以是一个物理单元的一部分，还可以以多个物理单元的组合实现。此外，为了突出本申请的创新部分，本实施方式中并没有将与解决本申请所提出的技术问题关系不太密切的单元引入，但这并不表明本实施方式中不存在其它的单元。
