参见图1所示为本申请实施例的一种可能的通信系统架构示意图。通信系统中包括互联网协议(internet protocol,IP)多媒体子系统(IP multimedia subsystem,IMS)网络和一个或者多个通话应用服务器。通话应用服务器也可以称为通话轻应用服务器,或者简称为轻应用服务器,或者采用其它的名称,本申请对此不作具体限定。后续描述时,以称为轻应用服务器为例。本申请实施例中将轻应用实现的通话称为数据通道(data channel,DC)通话,当然还可以采用其它的名称,本申请对此不作具体限定。
轻应用服务器可以为不同的终端设备的用户维护所能使用的通话轻应用。轻应用服务器是完成DC通话的重要网元,提供DC通话会话控制请求的转发、下发主页面、子页面等功能。
一些实施例中,轻应用服务器可以支持对通信双方运行通话轻应用的产生的媒体数据进行处理,比如逻辑运算、画面渲染、虚拟景象合成等等操作,本申请实施例对此不作具体限定。轻应用服务器可以是以容器服务的形式部署,也可以通过一个或者多个虚拟机来实现。轻应用服务器也可以包括一个或者处理器,或者通过一个或者多个计算机来实现,比如超多核计算机、部署有图形处理器(graphics processing unit,GPU)集群的计算机、大型的分布式计算机、硬件资源池化的集群计算机等等。
IMS网络中包括会话边界控制器(session border control,SBC)和呼叫会话控制功能(call session control function,P-CSCF)等核心网元。SBC位于IMS网络的边界,主要用于将终端设备接入到IMS网络和媒体资源处理。IMS网络中还可以包括归属签约用户服务器(home subscriber server,HSS),IMS网络中还可以包括其它网元,本申请实施例中不再赘述。CSCF是IMS网络的呼叫控制中心,是在IP传输平台上实现用户接入,鉴权、会话路由和业务触发等功能。CSCF可以包括服务-呼叫会话控制功能(serving-call session control function,S-CSCF)、代理-CSCF(Proxy CSCF,P-CSCF)、查询-CSCF(Interrogating-CSCF,I-CSCF)中的一个或多个。HSS用于记录用户的签约数据(比如用户信息、业务数据)。需要说明的是,为第一终端设备提供服务的IMS核心网元和为第二终端设备提供服务的IMS核心网元可以不同,比如与终端设备所在的位置相关,或者与终端设备所述的运营商有关。作为一种示例,本申请实施例所提及的IMS核心网元可以包括CSCF。
应理解,上述的说明并不构成对本申请实施例的系统架构图的限定,本申请实施例的系统架构图包括但不限于在图1所示。需要说明的是,轻应用服务器可以作为独立网元,也可以由已有业务中的应用服务器来实现。一些可能的实施例中,轻应用服务器可以部署于IMS网络内,也可以部署于IMS网络外。
两个终端设备可以通过通信系统运行通话轻应用以进行视频。终端设备可以是配置有显示屏,具有音视频通话功能的设备,比如,终端设备可以是可穿戴设备(例如电子手表),终端设备还可以是手机、平板电脑等设备。本申请实施例对终端设备的具体形式不作特殊限制。图1中以两个SBC为例,分别为SBC1和SBC2。SBC1用于管理第一终端设备,SBC2用于管理第二终端设备。另外,不同终端设备也可以由同一个SBC来管理。

在一些实施例中,参见图3所示,通信系统中还可以包括轻应用管理系统,用于对轻应用进行管理,比如在轻应用服务器中进行轻应用部署,或者为服务号服务器提供基于服务号的轻应用注册服务。
在一些实施例中,通信系统中还可以包括第三方服务器,参见图4所示,第三方服务器可以理解为第三方提供商的服务器,位于第三方网络。不同的第三方服务器可以对应不同的服务号。第三方服务器可以包括提供急救服务的服务器,提供报警服务的服务器等等。例如,用户通过终端设备拨打急救电话号时,可以与提供急救服务的服务器建立通信连接,与提供急救服务的坐席终端设备进行通信连接。例如,用户通过终端设备拨打报警电话号时,可以与提供报警服务的服务器建立通信连接,与提供报警服务的坐席终端设备进行通信连接。示例性地,第三方服务器也可以称为服务号服务器,当然还可以采用其它的名称,本申请实施例对此不作具体限定。
服务号服务器可以预先获取到轻应用服务器的地址,从而向轻应用服务器注册服务号信息。从而轻应用服务器可以建立服务号服务器的地址与服务号信息的关联关系,后续可以通过关联关系向服务号服务器请求提供轻应用服务。
本申请实施例可以适用于如下两种可能的场景中:
第一种可能的场景中,适用于电话号码通话类型。移动用户可以通过拨打电话号码触发DC通话,运行通话轻应用。
第二种可能的场景中,适用于服务号码通话类型。移动用户可以拨打服务号码触发DC通话,使得坐席为移动用户提供服务。
下面结合上述两种不同的场景,对本申请实施例提供的方案进行详细描述。
如下以第一终端设备与第二终端设备进行DC通话为例,第一终端设备与第二终端设备触发DC通话后,从轻应用服务器获取主页面的流程进行说明,参见图5所示。主页面也可以称为第一页面,主页面上指示有供第一终端设备与第二终端设备进行DC通话使用的多个应用。在描述图5所示的流程中,以图1所示的架构为例。第一终端设备与第二终端设备被同一个轻应用服务器提供服务。
501,第一终端设备发送第一请求,第一请求用于请求与第二终端设备之间建立DC通话。示例性地,第一请求可以是会话创建请求或者会话修改请求。第一终端设备与第二终端设备之间建立DC通话包括第一终端设备和第二终端设备分别与轻应用服务器之间建立用于传输页面的数据通道。为了便于区分将用于传输页面的数据通道称为DC引导通道。
本申请的第一种可能的场景中,第一终端设备触发第一请求,可以是第一终端设备的用户拨打第二终端设备的电话号码时触发的。本申请的第二种可能的场景中,第二终端设备可以是提供社会服务的坐席终端,第一终端设备触发第一请求,可以是第一终端设备的用户拨打服务号码时触发的。
一种可能的示例中,通过拨号盘界面触发DC通话。参见图6A所示,拨号盘界面中包括用于触发DC通话的控件。图6A通过DC电话标识。第一终端设备的用户可以针对DC电话控件执行操作,从而第一终端设备的响应于用户针对DC电话控件的操作,触发发送第一请求。该示例中第一请求可以是会话创建请求。
另一种可能的示例中,可以通过音频通话界面触发DC通话。参见图6B所示,音频通话界面中包括用于触发DC通话的控件。图6B通过DC电话标识。第一终端设备的用户可以针对音频通话界面上DC通话的控件执行操作,从而第一终端设备响应于用户针对DC电话控件的操作,触发发送第一请求。该示例中第一请求可以是会话修改请求。
另一种可能的示例中,可以通过视频通话界面触发DC通话。参见图6C所示,视频通话界面中包括用于触发DC通话的控件。图6C通过DC电话标识。第一终端设备的用户可以针对视频通话界面上DC通话的控件执行操作,从而第一终端设备响应于用户针对DC电话控件的操作,触发发送第一请求。该示例中第一请求可以是会话修改请求。
一种可能的实施方式中,第一终端设备可以在由第一终端设备的用户触发DC通话的操作时,向IMS网络发送第一请求,由IMS网络根据第一请求向轻应用服务器触发请求引导DC通道的建立。
502a,轻应用服务器接收到该第一请求后,与第一终端设备之间建立DC引导通道。为了便于描述,此处将轻应用服务器与第一终端设备之间建立的DC引导通道称为第一DC引导通道。
503a,轻应用服务器通过建立的第一DC引导通道向第一终端设备发送第一页面(主页面),从而该第一终端设备接收到该第一页面。
在一些实施例中,第一终端设备与轻应用服务器之间建立第一DC引导通道后,执行504a,第一终端设备可以向轻应用服务器发送第一页面请求,第一页面请求用于请求第一终端设备的主界面。从而轻应用服务器在接收到第一终端设备的第一页面请求后,再执行503a,通过第一DC引导通道向第一终端设备发送第一终端设备的主页面。
示例性地,在第一种可能的场景中,第一页面请求可以携带第一终端设备的用户标识,比如,用户ID。从而轻应用服务器根据第一终端设备的用户标识来获取第一终端设备的主界面,并发送给第一终端设备。在第二种可能的场景中,第一页面请求可以携带服务号码。从而轻应用服务器根服务号码来获取服务主界面,并发送给第一终端设备。
一种可能的实施方式中,第一终端设备与第二终端设备之间建立DC通话的过程中,轻应用服务器还与第二终端设备之间建立DC引导通道,用于向第二终端设备发送供第二终端设备使用的主页面。为了便于描述,此处将轻应用服务器与第二终端设备之间建立的DC引导通道称为第二DC引导通道。
一种可能的示例中,为被叫终端设备下发的主页面可以与为主叫终端设备下发的主页面相同。轻应用服务器接收到第一请求后,与第二终端设备建立第二DC引导通道。轻应用服务器通过建立的第二DC引导通道向第二终端设备发送第一页面。
另一种可能的示例中,轻应用服务器为第二终端设备下发的主页面可以与为第一终端设备下发的主页面不同。参见图5所示,轻应用服务器接收到该第一请求后,执行502b,第二终端设备与轻应用服务器完成第二DC引导通道的创建。然后执行503b,将第二终端设备的主页面下发给第二终端设备。在一些实施例中,第二终端设备与轻应用服务器之间建立第二DC引导通道后,执行504b,第二终端设备可以向轻应用服务器发送第二页面请求,比如可以通过第二DC引导通道向轻应用服务器发送第二页面请求,第二页面请求用于请求第二终端设备的主页面。从而轻应用服务器在接收到第二终端设备的第二页面请求后,再执行504b,通过第二DC引导通道向第二终端设备发送第二终端设备的主页面。示例性地,第二页面请求可以携带第二终端设备的用户标识。从而轻应用服务器根据第二终端设备的用户标识来获取第二终端设备的主页面,并发送给第二终端设备。
如下结合具体实施例在第一种可能的场景下对本申请实施例的方案进行描述。
下面结合图7A对第一终端设备触发与第二终端设备通话过程中,创建DC引导通道和下发主界面的流程进行说明。第一终端设备的用户可以在音频通话过程中触发DC通话或者在视频通话过程中触发DC通话,或者通过拨号盘界面触发DC通话。

另一种可能的示例中,可以通过音频通话界面触发DC通话。第一终端设备的媒体描述信息中还可以包括用于描述与轻应用服务器之间创建音频传输通道的参数。示例性地,第一终端设备与第二终端设备之间在建立音频通话时创建的音频传输通道无需进行更改,可以继续沿用,因此,第一终端设备的媒体描述信息中也可以不包括用于描述与轻应用服务器之间创建音频传输通道的参数,无需在重新建立音频传输通道。
另一种可能的示例中,可以通过视频通话界面触发DC通话。第一终端设备的媒体描述信息中还可以包括第一指示,该第一指示用于指示删除已建立用于视频通话过程中传输视频数据的通道。例如,SDP中用于描述视频的参数部分可以置为0,从而指示删除已建立用于视频通话过程中传输视频数据的通道。
示例性地,第一终端设备在向CSCF发送第一请求时,可以通过第一终端设备所属的SBC1向CSCF发送第一请求。
作为一种举例,媒体描述参数可以采用会话描述协议(session description protocol,SDP)。当然还可以采用其它的描述协议,本申请对此不作具体限定。后续描述时,以第一媒体描述参数采用SDP为例。

a=dcmap:10subprotocol="http",表示数据通道(DC)的stream ID,引导DC通道时stream ID小于1000。
ID=0/10/100/110分别表示内容(链接/应用)来源于本网运营商(第一终端设备的所属运营商)/第一终端设备/跨网运营商(第二终端设备所属运营商)/第二终端设备;子协议采用超文本传输协议(Hyper Text Transfer Protocol,HTTP)。图7B中,以ID=0为例。
a=dcmap:38754max-time=150;label="low latency",表示DC的stream ID,应用通道时stream ID大于等于1000,max-time与label中的low latency对应,最大时延为150ms。不特殊指定重传、丢包率等信息的情况下,则丢包率、时延以“a=3gpp-qos-hint:loss=0.01;latency=100”为限定条件为准。
a=dcmap:7216max-retr=5;label="low loss",表示与a=dcmap:38754为不同的应用通道,最大重传次数为5,需要更低的丢包率。不特殊指定重传、丢包率等信息的情况下,则丢包率、时延以“a=3gpp-qos-hint:loss=0.01;latency=100”为限定条件为准。
a=3gpp-qos-hint:loss=0.01;latency=100,表示服务质量(Quality of Service,QoS)信息,指定特定的丢包率和时延。其他DC通道不指定特殊条件的话,以该条为准。
图7B中SDP中的两个通道均指定特殊限定条件。

一种可能的实施方式中,针对运营商所提供或者推广某个通话轻应用时,可以将通话轻应用部署于轻应用服务器上。示例性地,可以通过轻应用管理系统将通话轻应用的部署文件发送给轻应用服务器上。参见图8所示,对通话轻应用部署流程进行描述。

一些可能的场景中,通信双方终端设备进行DC通话时,均显示DC通话的主页面,但是可能通信双方终端设备的用户均触发对主页面的某个轻应用的操作,如何保障通信双方运行同一个轻应用,值得研究。本申请实施例示例性地提供几种方式,以主叫终端设备请求第一应用,被叫终端设备请求第二应用为例:
第一种可能的实现方式,通信双方均为移动用户,轻应用服务器可以根据DC通话的发起方和DC通话的接受方来确定向两个终端设备分别发送哪个应用的页面。比如被叫跟随主叫,即将主叫终端设备作为主导方,轻应用服务器向两个终端设备分别下发第一应用的页面。
第二种可能的实现方式,通信双方均为移动用户,轻应用服务器可以根据DC通话的发起方和DC通话的接受方来确定向两个终端设备分别发送哪个应用的页面。采用主叫跟随被叫,即将被叫终端设备作为主导方,轻应用服务器向两个终端设备分别下发第二应用的页面。
第三种可能的实现方式中,根据通话类型、DC通话的发起方和DC通话的接受方来确定向两个终端设备分别发送哪个应用的页面。作为一种示例,通话类型为电话号码通话时,可以被叫跟随主叫,即由主叫终端设备作为主导方,轻应用服务器向两个终端设备分别下发第一应用的页面。作为另一种示例,通话类型为社会服务号通话时,可以主叫跟随被叫,由被叫终端设备作为主导方,即坐席终端作为主导方,轻应用服务器向两个终端设备分别下发第二应用的页面。
参见图17所示,以主叫终端设备触发使用第一应用,被叫终端设备触发第二应用为例进行说明。主叫终端设备也称为第一终端设备,被叫终端设备也称为第二终端设备。
1701,在主叫终端设备的触发下,与被叫终端设备建立DC通话后,主被叫均获取主页面或者服务号页面。
1702,轻应用服务器识别通话类型;
1703,轻应用服务器从CSCF获取主被叫信息。
1704,主叫终端设备向轻应用服务器发送请求第一应用的第一子页面请求。
1705,被叫终端设备向轻应用服务器发送请求第二应用的第二子页面请求。
1706,轻应用服务器根据通话类型和/或主被叫信息确定主页面为第一应用的页面或者第二应用的页面。
1707,轻应用服务器向第一终端设备发送主页面。
1708,轻应用服务器向第二终端设备发送所述主页面。
通过上述方案,根据通话类型、DC通话的发起方和DC通话的接受方来确定向两个终端设备分别发送哪个应用的页面,防止通话双方选择不同的应用时出现冲突。
第四种可能的实现方式中,被叫不允许参与应用的选择,主界面中各个应用图标是不允许被叫终端设备的用户操作的。
