通话连接方法及客户端
技术领域
本发明涉及通信技术领域，尤其涉及一种通话连接方法及客户端。
背景技术
随着通信技术的不断发展，通过终端设备进行音视频通话也越来越流行，在终端设备在进行音视频通话过程中，终端设备之间的网络环境是不同的，为了使得音视频通话过程中媒体数据从一个终端设备传送到另一个终端设备，需要在外网中部署一台服务器来转发媒体数据，由于所有的终端设备都依赖于该服务器进行媒体数据转发，因此使得服务器承受的压力非常大，容易当机；为了解决上述技术问题，引入（Internet Communication Engine，ICE）分布式转发通信机制，使得音视频通话过程中媒体数据从一个终端设备直接传送到另一个终端设备，当媒体数据无法从一个终端设备直接传送到另一个终端设备时，再通过外网中部署的服务器来转发媒体数据，从而实现终端设备之间的音视频通话，但由于终端设备之间的网络环境不同，因此终端设备之间的媒体数据无论是直接发送还是通过中转服务器发送，都必须检测终端设备之间的内网地址连通性、外网地址连通性以及中转站地址连通性，最后选择该三个地址中连通性最好的地址进行通话连接，因此耗费大量的音视频通话连接时间，从而降低了音视频通话连接效率。

本发明目的的实现、功能特点及优点将结合实施例，参照附图做进一步说明。
具体实施方式
应当理解，此处所描述的具体实施例仅仅用以解释本发明，并不用于限定本发明。
基于上述问题，本发明提供一种通话连接方法。
参照图1，图1为本发明通话连接方法的第一实施例的流程示意图。
在本实施例中，所述通话连接方法包括：
步骤S110，在接听客户端接收到主叫客户端发送的呼叫信息时，解析呼叫信息以获取主叫客户端对应的第一通话地址信息，并向第一通话地址信息中的第一中转站地址对应的中转站获取本端对应的第二通话地址信息；
在本实施例中，该接听客户端以及主叫客户端为支持RFC5766协议的ICE客户端，该接听客户端以及主叫客户端通过RFC5766协议与TURN Server中转站进行通讯，而该TURN Server中转站包括支持RFC5766协议的TURN Server客户端，用于以ICE中转服务器的角色为ICE客户端提供TURN中转服务。当主叫客户端开启音视频通话模式后，使用SIP会话发起协议，向接听客户端发送INVITE呼叫信息，而该INVITE呼叫信息由SDP协议构建的，该SDP协议在构建该INVITE呼叫信息的同时，也将该主叫客户端对应的第一内网地址、第一外网地址、两组第一中转地址以及第一网络地址转换NAT类型通过增加属性项的形式构建在该INVITE呼叫信息中，因而该主叫客户端在向该接听客户端发送INVITE呼叫信息的同时，也会将本端对应的第一内网地址、第一外网地址、两组第一中转地址以及第一网络地址转换NAT类型发送给该接听客户端。在该接听客户端接收到该主叫客户端发送的该INVITE呼叫信息后，解析该INVITE呼叫信息获取该主叫客户端对应的第一通话地址信息，其中，该第一通话地址信息包括该主叫客户端对应的第一内网地址、第一外网地址以及两组第一中转地址。当该接听客户端接收到该主叫客户端发送的两组第一中转地址，判断本端当前存储的第二中转地址与该两组第一中转地址是否相同，若是，则获取已存储的基于该第二中转地址对应的中转站获取的本端的第二外网地址、第二内网地址以及第二网络转换NAT类型，若否，则基于该两组第一中转地址对应的中转站获取本端的第二通话信息，该第二通话信息包括该接听客户端对应的第二内网地址、第二外网地址、两组第二中转站地址以及第二网络转换NAT类型。其中，该两组第一中转地址不同，且该两组第一中转地址与该两组第二中转地址一致。
步骤S120，接听客户端基于第一通话地址信息以及第二通话地址信息确定第一通话地址信息中各个通话地址的权重值，第一通话地址信息中的通话地址包括第一外网地址、第一内网地址以及第一中转站地址；
当接听客户端获取到本端的第二通话地址信息以及该主叫客户端的第一通话地址后，根据该第二通话地址信息以及该第一通话地址确定该第一通话地址信息中各个通话地址的权重值。其中，该第一通话地址信息中的各个通话地址包括第一外网地址、第一内网地址以及两组第一中转站地址。
步骤S130，接听客户端基于权重值最大的通话地址进行连通性测试，并将第一通话地址信息中各个通话地址的权重值发送至主叫客户端，以供主叫客户端基于权重值最大的通话地址进行连通性测试；
在该接听客户端确定该第一通话地址信息中各个通话地址的权重值后，将第一通话地址信息中各个通话地址的权重值按照从大到小的顺序进行排列，该接听客户端首先根据该第一通话地址信息中权重值最大的通话地址与该主叫客户端进行连通性测测试，若该权重值最大的通话地址连通失败，则选择排列第二的权重值对应的通话地址进行连通性测试，若按照权重值按照从大到小的顺序所对应的通话地址进行连通性测试都失败后，则该接听客户端根据两组第一中转站地址跳转至中转站，基于该中转站建立与该主叫客户端的通信连接。
步骤S140，在连通性测试测试成功时，接听客户端基于权重值最大的通话地址建立与主叫客户端的通信连接。
在接听客户端基于权重值最大的通话地址进行连通性测试成功后，该接听客户端基于该权重值最大的通话地址建立与该主叫客户端的通信连接。
可以理解的是，当该接听客户端确定该第一通话地址信息中某个通话地址的权重值为最小值如0时，以及第二通话地址信息中某个通话地址的权重值为最小值如0时，不需要进行连通性测试。
本实施例通过在接听客户端接收到主叫客户端发送的呼叫信息时，解析呼叫信息以获取主叫客户端对应的第一通话地址信息，并向第一通话地址信息中的第一中转站地址对应的中转站获取本端对应的第二通话地址信息，接听客户端基于第一通话地址信息以及第二通话地址信息确定第一通话地址信息中各个通话地址的权重值，第一通话地址信息中的通话地址包括第一外网地址、第一内网地址以及第一中转站地址，接听客户端基于权重值最大的通话地址进行连通性测试，并将第一通话地址信息中各个通话地址的权重值发送至主叫客户端，以供主叫客户端基于权重值最大的通话地址进行连通性测试，在连通性测试测试成功时，接听客户端基于权重值最大的通话地址建立与主叫客户端的通信连接。由于在接听客户端确定该主叫客户端对应的第一通话地址信息中各个通话地址的权重值后，该接听客户端基于权重值最大的通话地址进行连通性测试，因此优化了连通性检测程序，降低了连通性测试时间，从而降低了音视频通话连接时间，进而提高了音视频通话连接效率。
进一步的，请参照图2，为本发明第一实施例中步骤S120的细化步骤的流程示意图，该步骤S120中所述接听客户端基于所述第一通话地址信息以及所述第二通话地址信息确定所述第一通话地址信息中各个通的细化步骤包括：
步骤S121，判断第一通话地址信息中的第一外网地址与第二通话地址信息中的第二外网地址是否相同；
步骤S122，在第一外网地址与第二外网地址相同时，将第一通话地址信息中的第一内网地址的权重值设为第一预设值，将第一外网地址以及第一中转站地址的权重值设为第二预设值，其中，第一预设值大于第二预设值。
本实施例通过判断第一通话地址信息中的第一外网地址与第二通话地址信息中的第二外网地址是否相同，在第一外网地址与第二外网地址相同时，将第一通话地址信息中的第一内网地址的权重值设为第一预设值，将第一外网地址以及第一中转站地址的权重值设为第二预设值，其中，第一预设值大于第二预设值。由于通过比对确定接听客户端的第二外网地址与主叫客户端的第一外网地址相同时，则确定该接听客户端与该主叫客户端处于同一局域网内，从而确定该第一内网地址的权重值为最大，因此减少了该接听客户端确定各个通话地址的权重值的程序，从而降低了权重值的确定时间，提高了音视频通话连接效率。
进一步的，请参照图3，提出本发明通话连接方法的第二实施例的流程示意图，在该第二实施例中， S121之前，该通话连接方法包括：
步骤S150，在第一外网地址与第二外网地址不相同时，检测呼叫信息中主叫客户端的第一网络地址转换类型与本端的第二网络地址转换类型是否均为预设类型；
步骤S160，在第一网络地址转换类型与第二网络地址转换类型均为预设类型时，将第一中转站地址的权重值设为第三预设值，并将第一外网地址以及第一内网地址的权重值设为第四预设值，其中，第三预设值大于第四预设值。
步骤S170，在第一网络地址转换类型与第二网络地址转换类型不是预设类型时，将第一外网地址的权重值设为第五预设值，将第一中转站地址的权重值设为第六预设值，并将第一内网地址的权重值设为第七预设值，其中，第六预设值大于第七预设值，且小于第五预设值。
本实施例通过判断第一通话地址信息中的第一外网地址与第二通话地址信息中的第二外网地址是否相同，在第一外网地址与第二外网地址不相同时，检测呼叫信息中主叫客户端的第一网络地址转换类型与本端的第二网络地址转换类型是否均为预设类型，在第一网络地址转换类型与第二网络地址转换类型均为预设类型时，将第一中转站地址的权重值设为第三预设值，并将第一外网地址以及第一内网地址的权重值设为第四预设值，其中，第三预设值大于第四预设值，在第一网络地址转换类型与第二网络地址转换类型不是预设类型时，将第一外网地址的权重值设为第五预设值，将第一中转站地址的权重值设为第六预设值，并将第一内网地址的权重值设为第七预设值，其中，第六预设值大于第七预设值，且小于第五预设值。由于在第一外网地址与第二外网地址不相同时，表明该接听客户端与该主叫客户端的网络环境不同中，通过判断该主叫客户端的第一网络地址转换类型与本端的第二网络地址转换类型来进一步确定该主叫客户端对应的第一通话地址信息中的各个通话地址的权重值，因此使得第一通话地址信息中的各个通话地址的权重值的确定更加精确，从而使得该接听客户端基于权重值最大的该通话地址建立与该主叫客户端的通话连接更加稳定。
基于上述问题，本发明提供一种通话连接方法。
参照图4，图4为本发明通话连接方法的第三实施例的流程示意图。

步骤S230，主叫客户端基于权重值最大的通话地址进行连通性测试；
步骤S240，在连通性测试成功时，主叫客户端根据权重值最大的通话地址与接听客户端进行通话连接。
本实施例通过主叫客户端接收接听客户端基于呼叫信息发送的第一通话地址信息中各个通话地址的权重值，其中，接听客户端解析呼叫信息以获取主叫客户端对应的第一通话地址信息，并向第一通话地址信息中的第一中转站地址对应的中转站获取本端对应的第二通话地址信息，接听客户端基于第一通话地址信息以及第二地址信息确定第一地址信息中各个通话地址的权重值，并将第一通话地址信息中各个通话地址的权重值发送至主叫客户端，第一通话地址信息中的通话地址包括第一外网地址、第一内网地址以及第一中转站地址，主叫客户端基于权重值最大的通话地址进行连通性测试，在连通性测试成功时，主叫客户端根据权重值最大的通话地址与接听客户端进行通话连接。由于主叫客户端在接收到接听客户端发送的第一通话地址信息中各个通话地址的权重值时，基于权重值最大的通话地址进行连通性测试，因此优化了连通性检测程序，降低了连通性测试时间，从而降低了音视频通话连接时间，进而提高了音视频通话连接效率。
本发明进一步提供一种客户端。

所述判断单元121，用于判断第一通话地址信息中的第一外网地址与第二通话地址信息中的第二外网地址是否相同；
所述设置单元122，用于在第一外网地址与第二外网地址相同时，将第一通话地址信息中的第一内网地址的权重值设为第一预设值，将第一外网地址以及第一中转站地址的权重值设为第二预设值，其中，第一预设值大于第二预设值。
本实施例通过判断第一通话地址信息中的第一外网地址与第二通话地址信息中的第二外网地址是否相同，在第一外网地址与第二外网地址相同时，将第一通话地址信息中的第一内网地址的权重值设为第一预设值，将第一外网地址以及第一中转站地址的权重值设为第二预设值，其中，第一预设值大于第二预设值。由于通过比对确定接听客户端的第二外网地址与主叫客户端的第一外网地址相同时，则确定该接听客户端与该主叫客户端处于同一局域网内，从而确定该第一内网地址的权重值为最大，因此减少了该接听客户端确定各个通话地址的权重值的程序，从而降低了权重值的确定时间，提高了音视频通话连接效率。
进一步的，基于第一实施例，提出本发明客户端的第二实施例，在本实施例中，接听客户端还包括：检测模块150、第一设置模块160以及第二设置模块170。
所述检测模块150，用于在第一外网地址与第二外网地址不相同时，检测呼叫信息中主叫客户端的第一网络地址转换类型与本端的第二网络地址转换类型是否均为预设类型；
所述第一设置模块160，用于在第一网络地址转换类型与第二网络地址转换类型均为预设类型时，将第一中转站地址的权重值设为第三预设值，并将第一外网地址以及第一内网地址的权重值设为第四预设值，其中，第三预设值大于第四预设值。
所述第二设置模块170，用于在第一网络地址转换类型与第二网络地址转换类型不是预设类型时，将第一外网地址的权重值设为第五预设值，将第一中转站地址的权重值设为第六预设值，并将第一内网地址的权重值设为第七预设值，其中，第六预设值大于第七预设值，且小于第五预设值。
本实施例通过判断第一通话地址信息中的第一外网地址与第二通话地址信息中的第二外网地址是否相同，在第一外网地址与第二外网地址不相同时，检测呼叫信息中主叫客户端的第一网络地址转换类型与本端的第二网络地址转换类型是否均为预设类型，在第一网络地址转换类型与第二网络地址转换类型均为预设类型时，将第一中转站地址的权重值设为第三预设值，并将第一外网地址以及第一内网地址的权重值设为第四预设值，其中，第三预设值大于第四预设值，在第一网络地址转换类型与第二网络地址转换类型不是预设类型时，将第一外网地址的权重值设为第五预设值，将第一中转站地址的权重值设为第六预设值，并将第一内网地址的权重值设为第七预设值，其中，第六预设值大于第七预设值，且小于第五预设值。由于在第一外网地址与第二外网地址不相同时，表明该接听客户端与该主叫客户端的网络环境不同中，通过判断该主叫客户端的第一网络地址转换类型与本端的第二网络地址转换类型来进一步确定该主叫客户端对应的第一通话地址信息中的各个通话地址的权重值，因此使得第一通话地址信息中的各个通话地址的权重值的确定更加精确，从而使得该接听客户端基于权重值最大的该通话地址建立与该主叫客户端的通话连接更加稳定。
本发明进一步又提供一种客户端。
在主叫客户端的第五实施例中，主叫客户端包括：发送模块210、接收模块220、第二测试模块230以及连接模块240。
所述发送模块210，用于在主叫客户端进入音视频通话模式后，向接听客户端发送呼叫信息；
所述接收模块220，用于接收接听客户端基于呼叫信息发送的第一通话地址信息中各个通话地址的权重值，其中，接听客户端解析呼叫信息以获取主叫客户端对应的第一通话地址信息，并向第一通话地址信息中的第一中转站地址对应的中转站获取本端对应的第二通话地址信息，接听客户端基于第一通话地址信息以及第二地址信息确定第一地址信息中各个通话地址的权重值，并将第一通话地址信息中各个通话地址的权重值发送至主叫客户端，第一通话地址信息中的通话地址包括第一外网地址、第一内网地址以及第一中转站地址；
所述第二测试模块230，用于基于权重值最大的通话地址进行连通性测试；
所述连接模块240，用于在连通性测试成功时，根据权重值最大的通话地址与接听客户端进行通话连接。
本实施例通过主叫客户端接收接听客户端基于呼叫信息发送的第一通话地址信息中各个通话地址的权重值，其中，接听客户端解析呼叫信息以获取主叫客户端对应的第一通话地址信息，并向第一通话地址信息中的第一中转站地址对应的中转站获取本端对应的第二通话地址信息，接听客户端基于第一通话地址信息以及第二地址信息确定第一地址信息中各个通话地址的权重值，并将第一通话地址信息中各个通话地址的权重值发送至主叫客户端，第一通话地址信息中的通话地址包括第一外网地址、第一内网地址以及第一中转站地址，主叫客户端基于权重值最大的通话地址进行连通性测试，在连通性测试成功时，主叫客户端根据权重值最大的通话地址与接听客户端进行通话连接。由于主叫客户端在接收到接听客户端发送的第一通话地址信息中各个通话地址的权重值时，基于权重值最大的通话地址进行连通性测试，因此优化了连通性检测程序，降低了连通性测试时间，从而降低了音视频通话连接时间，进而提高了音视频通话连接效率。
以上仅为本发明的优选实施例，并非因此限制本发明的专利范围，凡是利用本发明说明书及附图内容所作的等效结构或等效流程变换，或直接或间接运用在其他相关的技术领域，均同理包括在本发明的专利保护范围内。
