为了便于更加清晰地理解本申请各实施例,首先对一些相关的背景知识进行如下介绍。
3GPP标准引入了在通话过程中建立DC的机制,通过DC可以在通话过程中进行额外的业务,例如进行屏幕共享,位置共享,文件传输等,从而给用户带来更好的体验。
不用的业务对应不同的DC application,该DC application可以在通话过程中动态下载到UE,不需要UE提前安装,方便用户使用。为了方便描述,下文将DC application简称为APP。
通信双方若启用某个APP,需要首先从DC服务器(Server)动态下载该APP,并为该APP建立对应的application DC。不同的APP有不同的服务质量(Quality of Service,QoS)需求,例如AR application要求低时延高吞吐,屏幕共享application要求实时性好等。通常每个APP都需要建立自己对应的application DC。
相关技术中,每个UE都可以根据自己支持的能力,选择需要在通话中使用的APP,目前存在如下2种方法:
方法1:UE将自身的DC能力发送给DC服务器,例如,数据通道信令功能(Data Channel Signaling Function,DCSF),DCSF根据UE的能力给UE下发一个应用列表(APP list),该APP list中的APP都是UE支持的,因此该UE可以根据用户的选择,发起APP的下载和application DC建立过程。
方法2:UE向DC服务器请求APP list,DC服务器在APP list中携带每个APP需要的能力,UE根据自身能力,判断可以使用的APP list并呈现给用户,因此该UE可以根据用户的选择,发起APP的下载和application DC建立过程。
图2是现有技术中下载应用的过程示意图;如图2所示,在图2中包括UE-A、UE-B以及DC服务器,UE-A和UE-B下载APP的具体步骤如下:
1a、UE-A与DC服务器建立初始化数据通道(Bootstrap Data Channel)。
1b、UE-B与DC服务器建立Bootstrap Data Channel。
2-3、可选地,UE-A和UE-B分别通过Bootstrap DC下载初始化应用(Bootstrap Application)。
4a、选项A:UE-A通过bootstrap DC向DC服务器发送UE能力;
选项B:UE-A基于HTTP请求(Req),从DC服务器获得DC application list,该DC application list中包含每个APP需要的能力信息。
4b、DC服务器根据UE-A的能力发送HTTP 200OK,该200OK中包括DC application list,该DC application list内的所有DC APP都是UE-A支持的APP。
5a-5b、UE-B执行步骤4a-4b相同的动作。
6、(仅针对选项B)UE-A根据DC application list和UE能力生成其可用的application list(即针对UE-A的能力细化应用列表)。
7、UE-A向用户展示可用的application list(即展示应用列表/菜单),以便用户选择。
8-9、UE-B执行步骤6-7。
10、UE-A或UE-B根据用户的选择下载APP,触发建立数据通道。
图3是现有技术中数据通道建立过程示意图;如图3所示,图3是UE-A向UE-B请求数据通道建立的过程,具体包括以下步骤:
1、UE-A向第一服务呼叫会话控制功能(Server-Call Session Control Function-1,S-CSCF-1)发送会话初始协议(Session initialization Protocol,SIP)重新邀请(re-invite)消息,以向UE-B发起建立application DC的协商请求。
具体地,UE-A通过SIP re-invite消息向UE-B发起建立application DC的协商请求,在该消息中携带待建立的application DC对应的APP的描述信息。
APP的描述信息可以是APP的ID或APP的下载链接地址,或流stream ID,其中stream ID用于表示DC的ID。
在该SIP re-Invite消息的会话描述协议(Session Description Protocol,SDP)中包含如下信息:
m=application 52718UDP/DTLS/SCTP webrtc-datachannel
b=AS:500
a=max-message-size:1024
a=sctp-port:5000
a=dcmap:7216max-retr=5;label=“low loss”
a=dcsa:7216;dcapp-id=“screen share”;
其中,m行代表媒体的类型为数据通道,52718代表端口号的取值;
b行代表该DC对应的带宽为500kbps;
a行代表该DC属性信息:
a=max-message-size:1024代表该DC能够传递消息的最大值为1024个字节;
a=sctp-port:5000代表该DC对应的端口号为5000;
a行内7216为stream ID,通常0-999用于表示bootstrap DC,大于等于1000的用于表示application DC。
a行内的dcapp id代表哪个APP在发起application DC的建立。
2-4、S-CSCF-1利用应用服务器(Application Server,AS)、DC服务器、第二服务呼叫会话控制功能(S-CSCF-2),将SIP re-Invite消息路由到UE-B。
5-8、若UE-B接受该application DC的建立,则UE-B回复200OK,200OK包括DC application accept,其被路由到UE-A。
综上所述,若UE-A选择使用某APP并发起application DC的建立过程,UE-B接受并完成application DC的建立,但是,由于UE-B不支持该application DC对应的APP,会导致应用无法正常使用。例如,以APP为屏幕共享application为例,当UE-A在通话过程中,选择使用屏幕共享APP,并向UE-B发起application DC的建立过程;基于相关技术,UE-B会直接接受并完成application DC的建立;但是实际上,若UE-B 的能力不支持屏幕共享application的情况下,UE-A发送屏幕共享请求后,UE-A无法收到UE-B的响应,另一方面,UE-B收到UE-A发送的屏幕共享数据之后,仅能显示未知数据,无法解析。
因此,如何建立application DC是亟待解决的技术问题。
下面结合附图,通过一些实施例及其应用场景对本申请实施例提供的数据通道建立方法进行详细地说明。
在本申请实施例中,第一终端接收到来自第二终端的用于请求建立DC的第一消息之后,第一终端基于第一消息向第二终端发送用于指示第一终端接受建立DC的第一响应消息,从而完成DC建立,或者第一终端基于第一消息向第二终端发送用于指示第一终端拒绝建立DC的第二响应消息,使得第二终端停止建立DC。
图4是本申请实施例提供的数据通道建立方法的流程示意图之一,如图4所示,该方法包括步骤401至步骤402;其中,
步骤401、第一终端接收来自第二终端的第一消息;所述第一消息用于请求建立数据通道DC,所述DC与目标应用对应。
需要说明的是,本申请实施例可应用于在通话过程中建立数据通道的场景中。所述第一终端、所述第二终端包括但不限于上述所列举的终端11的类型,本申请对此并不限定。
由于在第二终端请求与第一终端建立DC的过程中,第一终端的能力有可能不支持第二终端请求建立的DC对应的APP,进而会导致出现应用无法正常使用,用户体验差。
可选的,第一终端的能力有可能不支持第二终端请求建立的DC对应的APP,可以理解为第一终端的能力与APP的能力需求不一致,或者,第一终端的能力与APP的能力需求不匹配,或者,第一终端的能力低于APP的能力需求。
因此,为了避免出现应用无法正常使用,并提高用户体验,本申请实施例中,第一终端首先需要接收来自第二终端的第一消息,其中,第一消息例如为SIP re-invite消息,用于请求建立DC,DC与目标应用对应,即目标应用为DC支持的APP。

在本申请实施例中,在第一终端接收到来自第二终端的第一消息之后,第一终端会基于第一消息判断自身的能力是否支持目标应用;
在第一终端的能力支持目标应用的情况下,第一终端基于第一消息向第二终端发送用于指示第一终端接受建立DC的第一响应消息;或者,在第一终端的能力不支持 目标应用的情况下,第一终端基于第一消息向第二终端发送用于第一终端拒绝建立DC的第二响应消息。
可选的,第一终端的能力支持目标应用可以理解为第一终端可以使用目标应用进行通信;第一终端的能力不支持目标应用可以理解为第一终端不可以使用目标应用进行通信。
在本申请实施例中,第一终端接收到来自第二终端的用于请求建立DC的第一消息之后,第一终端基于第一消息向第二终端发送用于指示第一终端接受建立DC的第一响应消息,从而完成DC建立,或者第一终端基于第一消息向第二终端发送用于指示第一终端拒绝建立DC的第二响应消息,使得第二终端停止建立DC。

为了便于更加清晰地理解本申请实施例提供的数据通道建立方法,下面结合图6对数据通道建立方法进行进一步解释说明。图6是本申请实施例提供的数据通道建立过程示意图,如图6所示,图6是UE-A(即上文提及的第二终端)向UE-B(即上文提及的第一终端)请求数据通道建立的过程,具体包括以下步骤:
步骤601、UE-A向S-CSCF-1发送SIP re-invite消息,以向UE-B发起建立application DC的协商请求,SIP re-invite消息中携带待建立的application DC对应的目标应用的描述信息。
具体地,在SIP re-invite消息中携带待建立的application DC对应的目标应用的描述信息(即DC application描述);APP的描述信息可以是APP的ID或APP的下载链接地址,或流stream ID,stream ID用于表示DC的ID。
在该SIP re-Invite消息的SDP中包含如下信息:
m=application 52718UDP/DTLS/SCTP webrtc-datachannel
b=AS:500
a=max-message-size:1024
a=sctp-port:5000
a=dcmap:7216max-retr=5;label=“low loss”
a=dcsa:7216;dcapp-id=“screen share”;
其中,m行代表媒体的类型为数据通道,52718代表端口号的取值;
b行代表该DC对应的带宽为500kbps;
a行代表该DC属性信息:
a=max-message-size:1024代表该DC能够传递的消息的最大值为1024个字节;
a=sctp-port:5000代表该DC对应的端口号为5000;
a行内7216为stream ID,通常0-999用于表示bootstrap DC,大于等于1000的用于表示application DC。
a行内的dcapp id代表哪个APP在发起application DC的建立。
步骤602-604、S-CSCF-1利用AS、DC服务器、S-CSCF-2,将SIP re-Invite消息路由到UE-B。
步骤605、UE-B根据自身能力判断是否支持目标应用对应的能力需求。
具体地,UE-B可以通过以下至少一种方式判断自身能力是否支持目标应用对应的能力需求:
方式1、UE-B收到数据通道建立请求(即SIP re-Invite消息)后,UE-B根据目标应用的描述信息,判断该目标应用是否在UE-B的application list(即上文提及的第一application list)内,若否,则拒绝使用该目标应用;若是,则展示给用户,并根据用户的选择拒绝使用该目标应用或接受使用该目标应用。
方式2、UE-B收到数据通道建立请求后,UE-B根据目标应用的描述信息,通过application list(即上文提及的第二application list)获得该目标应用对应的能力需求,并根据自身的能力判断其是否支持该目标应用对应的能力需求,若否,则拒绝使用该目标应用;若是,则展示给用户,并根据用户的选择拒绝使用该目标应用或接受使用该目标应用。
在UE-B接受UE-A建立application DC的情况下,执行步骤606a-609a;否则,执行步骤606b-609b以及步骤610;
步骤606a-609a、UE-B向UE-A回复第一200OK消息,第一200OK消息包括DC application接受accept。
具体地,第一200OK消息为第一响应消息,利用S-CSCF-2、DC服务器、S-
CSCF-1路由到UE-A。
步骤606b-609b、UE-B向UE-A回复第二200OK消息。
具体地,第二200OK消息为第二响应消息,利用S-CSCF-2、DC服务器、S-CSCF-1路由到UE-A;
第二响应消息通过删除SDP中application DC对应的a行,代表UE-B拒绝建立该application DC;可选地,在第二响应消息中还携带拒绝建立application DC的原因。
例如,UE-A向UE-B发送的SDP中包含以下信息:
m=application 52718UDP/DTLS/SCTP webrtc-datachannel
b=AS:500
a=max-message-size:1024
a=sctp-port:5000
a=dcmap:7216max-retr=5;label=“low loss”
a=dcsa:7216;dcapp-id=“screen share”;
在UE-B向UE-A发送第二响应消息的情况下,UE-B向UE-A发送的SDP中包含以下信息:
m=application 52718UDP/DTLS/SCTP webrtc-datachannel
b=AS:500
a=max-message-size:1024
a=sctp-port:5000;
以下为SDP中包含的拒绝建立application DC的原因信息:
若UE-B的能力不匹配,则:
a=dcsa:7216;reject cause=“Mismatch of capabilities”;
若为UE-B的拒绝原因为用户拒绝,则:
a=dcsa:7216;reject cause=“Reject to use”;
步骤610、UE-A记录拒绝原因,并更新UE-A的应用列表(即上文提及的第三application list和/或第四application list)。
具体地,若拒绝原因为UE-B不支持的目标应用,则直接从UE-A的应用列表中删除;
若拒绝原因为UE-B拒绝使用的目标应用,则仍显示该目标应用,但是增加额外的标记。
