在本申请的描述中，需要理解的是，步骤前的数字标号并不标识执行步骤的前后顺序，仅用于方便描述本申请及区别每一步骤，因此不能理解为对本申请的限制。
WebRTC(Web Real-Time Communication，Web实时通信)是一项在浏览器内部进行实时视频和音频通信的技术，例如WebRTC可以实现基于网页的视频会议，其使得不同终端浏览器之间的直接web通信成为可能，从而改变了终端浏览器只能通过服务器拉取信息的网络结构模式，是对WEB技术的一大变革。发明人发现，建立WebRTC通信的双方均是通过信令服务器转发全部类型的互联网连接候选者信息给对方，从而给信令服务器带来过多网络带宽和性能消耗。
针对上述发现的问题，本申请旨在：在建立WebRTC过程中，双方尽量避免发送非必要信息，如仅将部分类型的互联网连接候选者信息发送信令服务器，以通过信令服务器转发给对方，从而有效减少信令服务器的网络带宽和性能消耗。
以下为本申请的术语解释：
WebRTC：全称Web Real-Time Communications，是一项实时通讯技术，它允许网络应用或者站点，在不借助中间媒介的情况下，建立浏览器之间点对点(Peer-to-Peer)的连接，实现视频流和(或)音频流或者其他任意数据的传输。
信令服务器(Signaling Server)：用于转发WebRTC客户端与WebRTC客户端之间消息的服务器。
RTCIceCandidate(互联网连接候选者信息)：是可能用于建立RTCPeerConnection的候选ICE(Internet Connectivity Establishment，因特网连接建立)配置。ICE候选者描述了WebRTC能够与被叫终端通信所需的协议和路由。启动WebRTC对等连接时，通常会在连接的每一端提出若干候选者，直到他们共同商定描述他们决定的连接将是最好的候选者。WebRTC使用该候选者的详细信息启动连接。
这些候选者分为多个类型，这些类型按优先级顺序列出。
Host类型：对应主机候选者，其RTCIceCandidate.ip属性中指定的IP地址实际上是远程对等方的真实地址。
srflx类型：对应服务器自反候选者(server reflexive candidate)，IP表示由STUN服务器分配的中间地址，用于匿名地表示候选者的对等方。
prflx类型：对应同等自反候选者(peer reflexive candidate)，IP是STUN服务器分配的中间地址，用于匿名地代表候选者的对等方。
relay类型：对应从TURN服务器获得的中继候选者(relay candidate)，中继候选者的IP地址是TURN服务器用来在两个对等方之间转发媒体的地址。
SDP(Session Description Protocol，会话描述协议)，用于两个会话实体之间的媒体协商。
图1示意性示出了根据本申请实施例的WebRTC通信方法的网络架构图。
主叫终端2，可以被配置为可以实施WebRTC通信的设备。主叫终端2可以包括任何类型的计算设备，诸如移动设备、平板设备、膝上型计算机、智能电视等。
信令服务器4，用于转发WebRTC客户端与WebRTC客户端之间消息的服务器。
被叫终端6，可以被配置为可以实施WebRTC通信的设备。被叫终端6可以包括任何类型的计算设备，诸如移动设备、平板设备、膝上型计算机、智能电视等。
主叫终端2、信令服务器4与被叫终端6之间可以通过一个或多个网络进行通信。所述一个或多个网络包括各种网络设备，例如路由器，交换机，多路复用器，集线器，调制解调器，网桥，中继器，防火墙，代理设备和/或类似。一个或多个网络可以包括物理链路，例如同轴电缆链路，双绞线电缆链路，光纤链路，其组合等。网络可以包括无线链路，诸如蜂窝链路，卫星链路，Wi-Fi链路等。
主叫终端2、被叫终端6各自安装浏览器或专门的应用程序。通过浏览器或专门的应用程序可以实现彼此之间的WebRTC通信，进而实现音频或视频通话等。主叫终端2、被叫终端6各自配置客户端接口，该客户端接口可以包括输入元件。例如，输入元件可以被配置为接收用户指令，所述用户指令可以实现各类操作。
在建立主叫终端2和被叫终端6之间的WebRTC连接过程中，主叫终端2和被叫终端6之间需要通过信令服务器4进行信息交换，以实现二者之间的通信协商。其中，所述信息可以包括媒体信息和网络信息(互联网连接候选者信息)等。
在上述示例性的网络架构下，本申请将提供多个用于WebRTC通信的实施例，具体参照下文。
实施例一
继续参考图1，本实施例提供了一种WebRTC通信系统。
如图1所示，所述WebRTC通信系统包括主叫终端2、信令服务器4和被叫终端6。
所述主叫终端2，用于获取所述主叫终端的第一设备信息与被叫终端的第二设备信息；根据所述第一设备信息与所述第二设备信息，判断是否有用于建立连接的主叫端非必要信息；及若有所述主叫端非必要信息，则收集不包括所述主叫端非必要信息的第一网络信息；及将所述第一网络信息通过所述信令服务器转发给所述被叫终端；
所述被叫终端6，用于获取所述第一设备信息与所述第二设备信息；根据所述第一设备信息与所述第二设备信息，判断是否有用于建立连接的被叫端非必要信息；及若有所述被叫端非必要信息，则收集不包括所述被叫端非必要信息的第二网络信息；及将所述第二 网络信息通过所述信令服务器转发给所述被叫终端；
所述信令服务器4，用于转发所述第一网络信息和所述第二网络信息，以使所述主叫终端和所述被叫终端建立WebRTC连接，并基于所述WebRTC连接进行通信。
本申请实施例所述的WebRTC通信系统，包括如下优点：主叫终端2和被叫终端6需要以信令服务器为中介交换用于建立WebRTC连接的信息。主叫终端2和被叫终端6在某些场景下，部分连接方式并不适用，因此对应的信息也可以被认为是非必要信息。在每次建立端与端之间的WebRTC连接时，若双方均将这部分非必要信息忽略掉(即不用于信息交换中)，则可以减少信令服务器30％以上的网络带宽和性能消耗，且不影响两端之间WebRTC建立连接的成功率。
在示例性的实施例中，所述第一设备信息包括所述主叫终端的第一公网IP地址，与所述第二设备信息包括所述被叫终端的第二公网IP地址；所述主叫终端2，还用于：判断所述第一公网IP地址与所述第二公网IP地址是否相同；若不相同，则判定主机类型的主叫端互联网连接候选者信息为所述主叫端非必要信息；所述被叫终端6，还用于：判断所述第一公网IP地址与所述第二公网IP地址是否相同；若不相同，则判定主机类型的被叫端互联网连接候选者信息为所述被叫端非必要信息。在本实施例中，将主机类型的主叫端/被叫端互联网连接候选者信息确定为非必要信息，可以有效减少双方发送给信令服务器4的网络带宽和性能消耗。
在示例性的实施例中，所述主叫终端2，还用于将非主机类型的主叫端互联网连接候选者信息通过所述信令服务器发送给所述被叫终端；所述被叫终端6，还用于将非主机类型的被叫端互联网连接候选者信息通过所述信令服务器发送给所述主叫终端。在本实施例中，将非主机类型的主叫端/被叫端互联网连接候选者信息用于WebRTC连接，可以有效减少双方发送给信令服务器4的网络带宽和性能消耗。
以下提供一个基于上述WebRTC通信系统的WebRTC连接示例。
主叫终端2和被叫终端6注册到信令服务器4中。
其中，主叫终端2可以向被叫终端6请求WebRTC连接。WebRTC连接过程如下：
步骤一：主叫终端2向信令服务器4获取自己的公网IP地址和被叫终端6的公网IP地址。
步骤二：主叫终端2调用PeerConnection接口，创建一个PeerConnection对象。
步骤三：主叫终端2调用该PeerConnection对象的CreateOffer方法创建一个offer SDP对象。其中，所述offer SDP对象可以保存有当前音视频的相关参数。
步骤四：主叫终端2经由信令服务器4将所述offer SDP对象发送给被叫终端6。
步骤五：被叫终端6接收所述offer SDP对象，调用PeerConnection的CreateAnswer方法创建应答SDP对象，并经由信令服务器4将所述应答SDP对象发送给主叫终端2。
步骤六：主叫终端2接收所述应答SDP对象，主叫终端2开启收集互联网连接候选者信息(如图2所示)。
步骤七：主叫终端2判断自己的公网IP地址和被叫终端6的公网IP地址是否相同；如果主叫终端2自己的公网IP地址和被叫终端6的公网IP地址不相同，进入步骤八；否则进入步骤九。
步骤八：主叫终端2收集除“主机类型的互联网连接候选者信息”之外的互联网连接候选者信息；进入步骤十。
步骤九：主叫终端2收集全部类型的互联网连接候选者信息；进入步骤十。
步骤十：主叫终端2将收集到的互联网连接候选者信息发送给信令服务器4，以经由信令服务器4转发给被叫终端6。
需要说明的是，被叫终端6镜像执行如步骤七至步骤十的操作，并将自己收集到的互联网连接候选者信息发送给信令服务器4，以经由信令服务器4转发给主叫终端2。
最后，主叫终端2和被叫终端6通过交换彼此的互联网连接候选者信息，选择一种方式建立WebRTC连接。基于该WebRTC连接，主叫终端2和被叫终端6可以实现通信。
如上，当主叫终端2的公网IP地址和被叫终端6的公网IP地址不相同时，双方给对方发送的互联网连接候选者信息都忽略掉主机(host)类型的互联网连接候选者信息，这样每建立一次端与终端之间的WebRTC连接，减少了信令服务器30％以上的网络带宽和性能消耗，并且不影响两端之间WebRTC建立连接的成功率。
实施例二
本实施例提供的WebRTC连接方法的技术细节可参考上文。
图3示意性示出了根据本申请实施例二的WebRTC通信方法的流程图。在示例性的实施例中，所述WebRTC通信方法可以执行在主叫终端2或被叫终端6中。

步骤S300，获取所述主叫终端的第一设备信息与被叫终端的第二设备信息；
步骤S302，根据所述第一设备信息与所述第二设备信息，判断是否有用于建立连接的非必要信息；及
步骤S304，若有所述非必要信息，则在排除所述非必要信息的情况下，在所述主叫终端和所述被叫终端之间建立WebRTC连接，以实现所述主叫终端和所述被叫终端的通信。
本申请实施例所述的WebRTC通信方法，包括如下优点：主叫终端2和被叫终端6需要以信令服务器为中介交换用于建立WebRTC连接的信息。主叫终端2和被叫终端6在某些场景下，部分连接方式并不适用，因此对应的信息也可以被认为是非必要信息。在每次建立端与端之间的WebRTC连接时，若双方均将这部分非必要信息忽略掉(即不用于信息交换中)，则可以减少信令服务器30％以上的网络带宽和性能消耗，且不影响两端之间WebRTC建立连接的成功率。
在示例性的实施例中，所述第一设备信息包括所述主叫终端的第一公网IP地址，与所述第二设备信息包括所述被叫终端的第二公网IP地址。如图4所示，所述步骤S302可以包括：步骤S400，判断所述第一公网IP地址与所述第二公网IP地址是否相同；步骤S402，若所述第一公网IP地址与所述第二公网IP地址不相同，则判定主机类型的互联网连接候选者信息为所述非必要信息。在本实施例中，将主机类型的互联网连接候选者信息确定为非必要信息，可以有效减少双方发送给信令服务器的网络带宽和性能消耗。
在示例性的实施例中，所述主机类型的互联网连接候选者信息和其他类型的互联网连接候选者信息构成互联网连接候选者信息。如图5所示，所述步骤S304可以包括：步骤S500，通过所述其他类型的互联网连接候选者信息，在所述主叫终端和所述被叫终端之间建立WebRTC连接。在本实施例中，将非主机类型的互联网连接候选者信息用于WebRTC连接，可以有效减少双方发送给信令服务器的网络带宽和性能消耗。
在示例性的实施例中，所述主机类型的互联网连接候选者信息和其他类型的互联网连接候选者信息构成互联网连接候选者信息。如图6所示，所述方法还可以包括：步骤S600，若所述第一公网IP地址与所述第二公网IP地址相同，则判定没有所述非必要信息；及步骤S602，通过所述互联网连接候选者信息，在所述主叫终端和所述被叫终端之间建立WebRTC连接。在本实施例中，将全部类型的互联网连接候选者信息用于WebRTC连接，有效确保主叫终端和被叫终端的WebRTC连接。
