Description

一种网络电话连接方法及装置 技术领域
本文涉及但不限于通信领域，尤其涉及一种网络电话连接方法及装置。
背景技术
在终端上，我们常常使用网络电话。在进入4G时代以后，移动互联网的网速更快，流量资费更低，因此我们在移动终端上使用网络电话更加频繁。
网络电话有一个天生的优点，即：基本上所有的网络电话都是加密传输的，其保密性优于普通电路域电话。
但是众所周知，网络电话存在一个较大缺点：即必须保持被叫方一直连接着数据网络，才能保证随时呼通被叫方。
而出于省钱、省电等原因，大部分用户的移动终端平时仅保持电路域一直在线，并没有连接上数据网络。所以我们不能够像拨打普通电路域电话一样可以随时使用网络电话拨打被叫方，这一点造成网络电话使用上的不方便。
因此，需要一种网络电话的连接方式，它不需要被叫方一直连接着数据网络，却能像拨打普通电路域电话一样，可以随时拨打被叫方。这种网络电话应该在接通电话过程中所耗时延方面与普通电路域电话相差不多，才能带给用户良好的体验。
相关技术中协议并未规定网络电话的连接方法，要能实现网络电话即时连接要么用户需要一直连接数据网络，要么修改协议栈来实现，最近***在推广一种应用在LTE网络上的网络电话即时连接方案，就是修改了协议栈，只有支持该协议的手机才能实现网络电话即时连接。
如果用户需要一直连接数据网络，就不能进入睡眠状态，否则就无法即时从睡眠中被唤醒，这样做很明显非常耗电，大大缩短了手机待机时间。
而***的方案，只能用在以后生产的支持该协议的新手机上，不能应用到自己已有的旧的3G,4G智能手机上，并且不能和电信、联通互通。可用的范围小。
针对相关技术中，不能像拨打普通电路域电话一样可以随时使用网络电话拨打被叫方的问题，还未提出有效的解决方案。

针对相关技术中存在的问题，本可选实施例提供一种网络电话连接方法，不需要被叫方一直连接着数据网络，却能像拨打普通电路域电话一样，可以随时拨打被叫方；以及使用该方法实现的终端。
本可选实施例的方案是这样设计的：
终端A是主叫方，终端B是被叫方，A和B均设置了当对方用其手机号码来电时，己方的来电界面可以出现通过数据网络通话的选项，双方均通过设置模块设置了进行数据网络通话时应该使用的网络电话软件(该设置双方需要一致)以及其他一些必要参数，包括：己方使用(即登录)网络电话软件的用户名和密码，对方使用网络电话软件的用户名；
上述网络电话软件应该已经安装在了A和B上，这类软件是可选择的，不特定指定某个软件，只要该软件能处理本方法规定的指令即可使用；
A使用一个专用的拨号软件拨电话给B，该拨号软件应从前述设置模块中读取到可以进行数据网络通话的联系人及其电话号码，该专用拨号软件只能拨打这些电话号码；
A用该拨号软件拨打B，一开始会拨出一个普通电路域电话给B；
B接到该电路域电话后，电话模块从前述设置模块中读取到A可以进行数据网络通话，于是在来电接听界面上多显示一个通过数据网络通话的选项；
如果B选择了通过数据网络通话的选项，就会挂断该电路域来电，然后自动连接上数据网络，并按预先设置的参数启动前述设置的网络电话软件等待A通过网络再次呼入；这些参数有：B使用网络电话的用户名和密码，A使用网络电话的用户名，以及一组给网络电话的指令：(a)等待A呼入；(b)自动/手动接听该呼入；(c)等待A呼入超时时间设置。
A在B挂断电话后，也会自动连接上数据网络，并按预先设置的参数启动前述设置的网络电话软件；这些参数有：A使用网络电话的用户名和密码，B使用网络电话的用户名，以及一组给网络电话的指令：(a)一旦B上线立即呼出；(b)等待B上线超时时间设置。
如果一切顺利，A和B将会组成一路网络通话。
本可选实施例提供了一种网络电话的连接方法，请参考图8，图8是根据本发明实施例的网络电话连接方法的流程示意图，包括S801～S804：
步骤S801：主叫方(即主叫终端)用专用的拨号软件发起网络通话，首先会拨出一个普通电路域电话给被叫方(即被叫终端)；
步骤S802：被叫方在接听界面选择网络通话选项后，会自动挂断这个电路域电话，之后主动连接上数据网络，启动网络电话软件等待；
步骤S803：主叫方在被叫方挂断前述电路域电话后，也会自动连接上数据网络，启动网络电话软件等待被叫方上线；
步骤S804：检测到被叫方上线后，主叫方使用网络电话软件自动呼出，双方建立起网络通话。
本可选实施例中，主被叫双方均要设置当对方用其手机号码来电时，己方的来电界面可以出现通过数据网络通话的选项，双方均设置了进行数据网络通话时应该使用的网络电话软件(该设置双方需要一致)以及其他一些必要参数，包括：己方使用网络电话软件的用户名和密码，对方使用网络电话软件的用户名。
上述网络电话软件并不特定指定某个软件，只要该软件能处理本方法规 定的指令即可。
被叫方启动网络电话软件进入等待时的参数有：被叫方使用网络电话的用户名和密码，主叫方使用网络电话的用户名，以及一组给网络电话的指令：(a)等待主叫方呼入；(b)自动/手动接听该呼入；(c)等待主叫方呼入超时时间设置。
下面用一个过程示意图说明该网络电话连接方法。
图9是根据本发明实施例的网络电话建立连接时被叫方没有连接着数据网络时的流程示意图。
前提：网络电话建立连接时被叫方没有连接上数据网络，仅仅连接着电路域，可以接收来自于电路域的电话。
如图9所示，该流程包括如下步骤S901～S907：
步骤S901是主叫方通过电路域向被叫方拨打电话；
步骤S902是被叫方接到来自电路域的电话；
步骤S903是被叫方根据来电号码判断出可以进行数据网络通话，并且被叫方选择了进行数据网络通话，于是被叫方自动挂断这个电话；
步骤S904是被叫方向数据网络发起连接请求；
步骤S905是被叫方连接数据网络成功；
步骤S906主叫方在被叫方挂断前述电路域电话后，向数据网络发起连接请求；
步骤S907是主叫方连接数据网络成功，启动网络电话软件等待被叫方上线；
至此，双方均已连上数据网络并登陆网络电话软件，一旦主叫方检测到被叫方上线，主叫方会使用网络电话软件自动呼出，双方建立起网络通话。
主叫方对于本网络通话连接方法的处理逻辑的实施例
图10是根据本发明实施例的主叫方对于本网络通话连接方法的处理流程图，如图10所示，按时间先后顺序说明如下：
不是任何电话号码都可以用本可选实施例的方法拨打，拨打前需要从前 述设置模块中读取到可以进行数据网络通话的联系人及其电话号码，只能拨打这些电话号码，所以可以使用一个专用拨号软件来保证后面的连接流程按照本方法设计的逻辑运行；
主叫方先向被叫方拨出一个普通的电路域电话，然后等待被叫方主动挂断电话；
一旦被叫主动挂断电话，主叫方就主动连接数据网络；并登陆网路电话软件等待，一旦检测到被叫方上线就自动呼出，双方建立起网络通话。
如果连接数据网络失败，或者登陆网络电话软件失败，并且重试一定次数仍然失败，又或者等待超时，就放弃本次网络通话。
被叫方对于本网络通话连接方法的处理逻辑的实施例
图11是根据本发明实施例的被叫方对于本网络通话连接方法的处理流程图，如图11所示，按时间先后顺序说明如下：
在正常被叫流程中，被叫方终端的协议栈在向MSC发送层三消息Call Confirmed之后，就会一方面向MSC发送层三消息Alerting(意思是被叫方已经响铃)，同时另一方面向MMI(Multi-Media Interface，多媒体接口)发送RING消息，该消息通知MMI应该显示来电界面了；
MMI在收到RING消息后，会检查来电号码，如果从前述设置模块中读取到这个电话号码可以进行数据网络通话，就会在来电接听界面上多显示一个数据网络通话选项；
如果从前述设置模块中读取到这个电话号码不可以进行数据网络通话，就按正常流程处理，显示普通来电界面；
如果用户选择网络通话选项，就自动挂断该来电；
在挂断来电之后，被叫方自动去连接数据网络；
如果连接数据网络成功，就自动登陆网络电话软件，等待主叫方呼入；
如果连接数据网络失败，或者登陆网络电话软件失败，被叫方会在一定时间范围内重试一定次数，如果还不成功，就放弃本次网络通话。
对网络电话软件的要求的实施例
网络电话软件是本连接方法流程的重要组成部分，但是指定使用哪种网络电话软件却是可选的。只要满足能处理本方法规定的指令即可使用。
指令1：等待呼出指令
参数有：
己方登陆网络电话软件的用户名和密码；
被等待的对方登陆网络电话软件的用户名；
等待超时时长；
等待呼出指令会在一旦对方上线就立即呼出网络电话。在等待超时前的这段时间内，不接受其他任何用户的网络通话请求。
指令2：等待呼入指令
参数有：
己方登陆网络电话软件的用户名和密码；
被等待的对方登陆网络电话软件的用户名；
自动/手动接听该呼入；
等待超时时长；
等待呼入指令可以设置一旦呼入就自动接听，这样连接速度会快点，也可以指定需要手动接听，给被叫方一次拒接的机会。在等待超时前的这段时间内，不接受其他任何用户的网络通话请求。
以下是一个实现了本发明的实例和一个用于实现该实例的手机：
在该实例分为专用拨号程序和被叫方程序以及设置程序三部分，在手机出厂时就预置在手机中，不可删除，分别体现为***的拨号界面，***的来电界面和***的联系人应用；
不指定该实例选用的网络通话软件，唯一的要求是该软件能和本连接方法配合，执行前述的指令，能加密通话；
用户可以在***的联系人界面，将某个联系人的某个电话号码标记为可以进行数据网络通话，同时设置与该联系人进行数据网络通话时所选用的网络通话软件，并设置必要的参数：己方登陆该网络电话软件的用户名和密码， 以及该联系人登陆该网络电话软件的用户名；
打开拨号界面，如果被拨打的电话号码被标记为可以进行数据网络通话，就会出现一个“网络通话”按钮；按下这个按钮，会拨出一个电路域电话，从拨出开始直到对方挂断电话，一直显示“正在呼叫”界面，这和普通电路域电话时一致的；
被叫方接到来电，如果来电号码标记为可以进行数据网络通话，在***来电界面中就会多一个“网络通话”按钮；按下这个按钮，会挂断来电，并且自动连接数据网络，同时向所选用的网络通话软件发出“等待呼入指令”，告知它己方登陆网络电话软件的用户名和密码，被等待的对方登陆网络电话软件的用户名，要求自动接听，超时等待时长为30秒；然后来电界面消失，取而代之的是网络通话软件会弹出“等待连接”界面；
主叫方收到电路域电话被挂断的通知后，自动连接数据网络，同时向所选用的网络通话软件发出“等待呼出指令”，告知它己方登陆网络电话软件的用户名和密码，被等待的对方登陆网络电话软件的用户名，超时等待时长为30秒；然后拨号界面消失，取而代之的是网络通话软件会弹出““等待连接”界面；
至此，双方均进入了“等待连接”界面，一旦连接建立，就可以开始网络通话；
30秒之后，如果连接未建立，提示用户网络通话失败；
在“正在呼叫”界面和“等待连接”界面，均有“挂断”按钮，按下后，己方终止上述连接流程。但没有通知对方，对方会继续流程直到超时结束；
被叫方有可能在来电界面选择“挂断”，终止上述连接流程。但没有通知对方，对方会继续流程直到超时结束；
如果被叫方在来电界面没有进行任何选择，该电路域电话会因为超时未接听而挂断，但是主叫方能从收到的挂断的通知中拿到原因，知道是超时未接听导致的挂断，于是终止上述连接流程，提示用户“对方未接听”；
相关技术中的手机就是实现了本文所述网络电话连接方法，可以使用该连接方法互相拨打网络电话的终端；
该实例制作的应用程序并非必须在出厂时预置在手机中，也可以作为第三方应用(专用拨号程序、监听来电模块、专用设置程序)安装在手机上，仍然可以在来电界面显示“网络通话选项”(例如以悬浮窗形式显示该选项)和主动连接/断开数据网络。
当被叫方手机处于睡眠状态时，来自电路域的电话会唤醒手机，再触发前述建立网络通话连接的流程。
综上所述，通过本发明实施例提供的网络电话连接方法和终端，在接通电话过程中所耗时延以及在接通率方面与普通电路域电话相差不多，用户体验良好；不需要一直连接数据网络，省电；在智能机上以第三方应用形式安装，可以跨不同制式手机使用，使用范围大；
显然，本领域的技术人员应该明白，上述的模块或步骤可以用通用的计算装置来实现，它们可以集中在单个的计算装置上，或者分布在多个计算装置所组成的网络上，可选地，它们可以用计算装置可执行的程序代码来实现，从而，可以将它们存储在存储装置中由计算装置来执行，并且在某些情况下，可以以不同于此处的顺序执行所示出或描述的步骤，或者将它们分别制作成集成电路模块，或者将它们中的多个模块或步骤制作成单个集成电路模块来实现。这样，本发明实施例不限制于任何特定的硬件和软件结合。
工业实用性
本发明实施例中，被叫终端接收主叫终端通过电路域发送的电路域呼叫请求；在被叫终端确定通过数据网络与主叫终端进行通话的情况下，被叫终端拒绝该电路域呼叫请求；被叫终端通过数据网络与主叫终端建立网络电话连接，可解决相关技术中不能像拨打普通电路域电话一样可以随时使用网络电话拨打被叫方的问题，进而实现了不需要被叫终端一直连接着数据网络，却能像拨打普通电路域电话一样，可以随时拨打被叫终端。
