具体实施方式
为更进一步阐述本发明为达成预定目的所采取的技术手段及功效，以下结合附图及较佳实施例，对本发明进行详细说明如后。
本发明提供的语音大话务仿真方法采用控制面和媒体面相分离的分布式系统架构，即语音大话务仿真系统包括信令面控制单元和媒体面控制单元，其中信令面控制单元为主控单元，媒体面控制单元为分布式部署的控制单元。该语音大话务仿真方法中，信令面控制单元按照一定频率(每秒建立呼叫数量，CPAS-Call Attempts Per  Second)向核心网辅助网元系统发起呼叫控制指令，当呼叫双方(主叫端和被被叫端)之间的通话接通后，信令面控制单元通知媒体面控制单元向被测网元系统发送语音媒体报文，由此媒体面控制单元模拟真实手机，向被测网元系统发送语音媒体报文。
本发明提出的语音大话务仿真方法，可以有效地提高核心网络验证的效率，减少人力成本，并且可以仿真大量手机呼叫，向核心网被测网元系统MGW发送语音报文，下面将详细地描述本发明的语音大话务仿真方法及其各个步骤。
第一实施例
如图1所示，本实施例的语音大话务仿真方法，在信令面控制单元侧，执行的流程包括：步骤S10：确认通话接通；以及，步骤S20：通知媒体面控制单元向被测网元系统，例如核心网被测网元系统MGW(Media Gateway)发送语音媒体报文。信令面控制单元按照一定频率(每秒建立呼叫数量，CPAS-Call Attempts Per Second)向核心网辅助网元系统发起呼叫控制指令，并根据核心网辅助网元系统-MSCe(Mobile Switching Center emulation)/MSC server回复的主叫消息或者被叫消息中的有用信息，通知媒体面控制单元建立数据区。当媒体面控制单元设置的处理数据区的循环定时时长到来后，媒体面控制单元遍历所建立的数据区，向被测网元系统MGW发送语音媒体报文。采用本实施例的语音大话务仿真方法，能够低成本地仿真多个手机进行语音的批量发送和接收。
其中，步骤S10中的确认通话接通可以是仿真完成，作为优选地，步骤S10：确认通话接通，具体包括：发起呼叫控制指令至核心网辅助网元系统，以使核心网辅助网元系统MSCe(Mobile Switching Center emulation)/MSC server和信令面控制单元建立正常呼叫所需的信令交互序列，其中包括呼叫连接信令等；接收到核心网辅助网元系统的呼叫连接成功信令后，确认通话接通。
第二实施例
如图2所示，在第一实施例的基础上，步骤S20：通知媒体面控制单元向被测网元系统发送语音媒体报文之前，本实施例的语音大话务仿真方法还包括：步骤S30：设置一个媒体面控制单元对应一个手机号码段。相应地，步骤S20：通知媒体面控制单元向被测网元系统发送语音媒体报文，具体包括：步骤S200：根据手机号码段的索引，选取多个媒体面控制单元；步骤S201：通知多个媒体面控制单元向被测网元系统发送语音媒体报文。由于可以选取多个媒体面控制单元，本方法由此达到较大的呼叫性能，可以模拟上万部真实手机同时发起呼叫的性能。
第三实施例
如图3所示，本实施例提供的语音大话务仿真方法在媒体面控制单元侧，执行的流程包括：步骤S40：在信令面控制单元确认通话接通的条件下，向被测网元系统发送语音媒体报文。信令面控制单元确认通话接通后，通知媒体面控制单元向被测网元系统发送语音媒体报文，进行语音大话务的仿真测试。
第四实施例
如图4所示，在第三实施例的基础上，步骤S40：向被测网元系统发送语音媒体报文之前，本实施例的语音大话务仿真方法还包括：步骤S50：录入不同编码格式的语音样本文件，作为语音媒体报文，并且选取语音媒体报文的编解码格式，编解码格式的选取是根据信令面控制单元和核心网辅助网元系统之间的交互信令确定的，信令面控制单元接收到核心网辅助网元系统发来的caBearerUpdReq_T消息时，会获取到该消息带来的语音媒体报文的编解码格式、语音媒体报文的PT值和语音媒体报文的帧数等信息，然后信令面控制单元将这些信息发送给媒体面控制单元，由此媒体面控制单元获取到语音媒体报文的编解码格式；以及，步骤S60：设置发送语音媒体报文的循环定时时长。根据语音媒体报文的帧数设置相应的循环定时时长，由此可以仿真实际手机进行不同语音媒体报文帧数的大话务仿真测试，另外还采用了可修改、可替换、可设置的语音样本报文，来替代真实手机通话时的语音媒体报文，向核心网被测网元系统，发起语音大话务仿真测试。
第五实施例
如图5所示，在第四实施例的基础上，步骤S40：向被测网元系统发送语音媒体报文之前，本实施例的语音大话务仿真方法包括：步骤S70：基于核心网辅助网元系统发送至信令面控制单元的主叫消息或者被叫消息，创建数据区。如果是主叫消息，则媒体面控制单元创建对应主叫端的数据区，如果是被叫消息，则媒体面控制单元创建对应被叫端的数据区。因此在步骤S40中存在步骤S400：基于数据区，模拟手机向被测网元系统发送语音媒体报文。
呼叫的建立、呼叫的结束等指令的发出都是由信令面控制单元和核心网辅助网元系统之间的消息交互发出。信令面控制单元根据消息交互的内容和接收到消息的时机，来控制媒体面控制单元什么时候创建数据区，如何创建数据区，以及何时删除数据区等。
本实施例通过数据区的创建、保持和清除，来模拟真实手机的呼叫、通话和挂机行为，一个数据区对应一部参与通话的真实手机，数据区保存发送语音媒体报文所必需的信息，可以通过创建大量数据区来实现语音大话务的仿真测试。每当发送语音媒体报文的循环定时时长到来之时，所有参与通话的仿真手机向被验证系统发送设置好的语音媒体报文，以此来实现语音大话务仿真，当一个仿真手机通话结束后，自动删除数据区以及数据区中对应的仿真信息。
作为优选地，主叫消息为承载更新请求消息例如caBearerUpdReq_T，被叫消息为呼叫连接消息，例如caConnect_T消息。承载更新请求消息或者呼叫连接消息带上对应主叫端或者被叫端的IP地址和端口号，以及语音媒体报文的编解码格式、语音媒体报文的PT值和语音媒体报文的帧数等。因此，步骤S70：基于核心网辅助网元系统发送至信令面控制单元的主叫消息或者被叫消息，创建数据区，具体包括：设置 数据区具有对应主叫端或者被叫端的IP地址和端口号，以及语音媒体报文的编解码格式、语音媒体报文的PT值和语音媒体报文的帧数。相应地，步骤S400：基于所述数据区，模拟手机向所述被测网元系统发送所述语音媒体报文，具体包括：步骤S401：根据数据区对应主叫端或者被叫端的IP地址和端口号，以及语音媒体报文的编解码格式、语音媒体报文的PT值和语音媒体报文的帧数组织UDP报文；步骤S402：根据IP地址和端口号发送UDP报文至被测网元系统。
第六实施例
如图6所示，在第五实施例的基础上，步骤S400：基于数据区，模拟手机向被测网元系统发送语音媒体报文之前，本实施例的语音大话务仿真方法还包括：步骤S403：当循环定时时长到来时，选取数据区队列中的第一个数据区，并且判断第一个数据区否为最后一个数据区；以及，若所述第一个数据区为最后一个数据区，则执行步骤S401：根据第一个数据区的对应主叫端或者被叫端的IP地址和端口号，以及语音媒体报文的编解码格式、语音媒体报文的PT值和语音媒体报文的帧数组织UDP报文；以及步骤S402：根据对应主叫端或者被叫端的IP地址和端口号发送UDP报文至被测网元系统后结束。
若第一个数据区不为最后一个数据区，则执行步骤S401：根据第一个数据区的对应主叫端或者被叫端的IP地址和端口号，以及语音媒体报文的编解码格式、语音媒体报文的PT值和语音媒体报文的帧数组织UDP报文；以及在步骤S402：根据对应主叫端或者被叫端的IP地址和端口号发送UDP报文至被测网元系统后，执行步骤S404：选取并且基于数据区队列中的下一个数据区向被测网元系统发送语音媒体报文，直到选取完数据区队列中的所有数据区。
第七实施例
在第五实施例的基础上，在步骤S70：基于核心网辅助网元系统发送至信令面控制单元的主叫消息或者被叫消息，创建数据区之后，本实施例的语音大话务仿真方法还包括步骤S80：基于核心网辅助网元系统发送至信令面控制单元的结束呼叫指令，删除数据区。当一路通话结束之后，媒体面控制单元根据信令面控制单元发来的结束呼叫指令，删除对应主叫端的数据区和被叫端的数据区，以保证数据区的个数与实际参与通话的模拟手机的个数一一对应。例如信令面控制单元收到核心网辅助网元系统发送的caClearCmd_M消息时，通知媒体面控制单元删除对应主叫端的数据区和对应被叫端的数据区。
第八实施例
如图7所示，本实施例的语音大话务仿真装置设置于信令面控制单元，所述装置包括：确认模块10，用于确认通话接通；以及，通知模块20，用于通知媒体面控制单元向被测网元系统发送语音媒体报文。
作为优选地，确认模块10具体用于：发起呼叫控制指令至核心网辅助网元系统， 与核心网辅助网元系统建立正常呼叫所需的信令交互序列；接收到核心网辅助网元系统的呼叫连接成功信令后，确认通话接通。
第九实施例
如图8所示，本实施例的语音大话务仿真装置还包括设置模块30，用于：设置一个媒体面控制单元对应一个手机号码段；调用所述通知模块20：根据手机号码段的索引，选取多个媒体面控制单元；通知多个媒体面控制单元向所述被测网元系统发送语音媒体报文。由此可以模拟大量真实手机同时拨打电话的情形。
第十实施例
如图9所示，本实施例的语音大话务仿真装置设置于媒体面控制单元，包括：报文发送模块40，用于在信令面控制单元确认通话接通的条件下，向被测网元系统发送语音媒体报文。由信令面控制单元按照一定的频率(每秒建立呼叫数量，CPAS-Call Attempts Per Second)不停的发起呼叫、结束呼叫的流程，这样保证不停的有新的仿真手机参与通话，同时也有通话一定时间后的仿真手机结束通话状态，使得参与通话状态的仿真手机平衡的维持在一定的数目。
第十一实施例
如图9所示，本实施例在第十实施例的基础上，该语音大话务仿真装置还包括预处理模块60，用于：录入不同编码格式的语音样本文件，作为语音媒体报文，并且选取语音媒体报文的编解码格式；设置发送语音媒体报文的循环定时时长；调用报文发送模块，向被测网元系统发送语音媒体报文。
循环定时器的定时时长对应于EVRC、QCELP13K、QCELP8K等格式的语音媒体报文，如果是一帧的话，循环定时时长为20ms，多帧则为20×帧数ms。其它语音格式的循环定时时长类似，具体时长根据协议标准来设定的。
当媒体面控制单元接收到语音媒体报文时，根据语音媒体报文来源的IP地址和端口号查找对应接收端的数据区，然后根据数据区保存的语音媒体报文的格式信息，进行语音解码，并且在语音解码之后进行保存，保存下来的文件可以作为语音大话务通话质量的分析资料。
第十二实施例
如图9和图10所示，在第十一实施例的基础上，本实施例的语音大话务仿真装置还包括数据区管理模块50，用于基于核心网辅助网元系统发送至信令面控制单元的主叫消息或者被叫消息，创建数据区；调用报文发送模块，基于数据区，模拟手机向被测网元系统发送语音媒体报文。数据区管理模块50实现有多少处于通话状态的仿真手机就在媒体面控制单元中建立多少个仿真手机数据区。
作为优选地，主叫消息为承载更新请求消息，被叫消息为呼叫连接消息，承载更新请求消息或者呼叫连接消包括对应主叫端或者被叫端的IP地址和端口号，以及语音媒体报文的编解码格式、语音媒体报文的PT值、语音媒体报文的帧数；数据区管 理模块50具体用于：设置数据区具有对应主叫端或者被叫端的IP地址和端口号，以及语音媒体报文的编解码格式、语音媒体报文的PT值和语音媒体报文的帧数。相应地，报文发送模块40具体用于：根据数据区对应主叫端或者被叫端的IP地址和端口号，以及语音媒体报文的编解码格式、语音媒体报文的PT值和语音媒体报文的帧数组织UDP报文；根据对应主叫端或者被叫端的IP地址和端口号发送UDP报文至被测网元系统。每个仿真手机对应的数据区中均保存承载更新消息或者呼叫连接消息带上的对应主叫端或者被叫端的IP地址和端口号，以及语音媒体报文的编解码格式、语音媒体报文的PT值、语音媒体报文的帧数，以及记录的上一次从语音样本文件中读取语音的位置等发送语音媒体报文的必需信息。报文发送模块40按照设定的循环定时时长遍历数据区，向被验证系统发送语音媒体报文。
第十三实施例
如图9和图10所示，本实施例的语音大话务仿真装置中的报文发送模块40，还用于：当循环定时时长到来时，选取数据区队列中的第一个数据区，并且判断第一个数据区是否为最后一个数据区；若第一个数据区为最后一个数据区，则根据第一个数据区的对应主叫端或者被叫端的IP地址和端口号，以及语音媒体报文的编解码格式、语音媒体报文的PT值和语音媒体报文的帧数组织UDP报文，并且根据对应主叫端或者被叫端的IP地址和端口号发送UDP报文至被测网元系统后结束；若第一个数据区不为最后一个数据区，则根据第一个数据区的对应主叫端或者被叫端的IP地址和端口号，以及语音媒体报文的编解码格式、语音媒体报文的PT值、语音媒体报文的帧数和上次语音样本文件中读取的位置等信息组织UDP报文，并将本次从语音样本文件中读取语音的位置保存在当前数据区中，以备下次发送语音媒体报文时从这个位置开始读取。然后根据对应主叫端或者被叫端的IP地址和端口号发送UDP报文至被测网元系统后，选取并且基于数据区队列中的下一个数据区向被测网元系统发送语音媒体报文，直到选取完数据区队列中的所有数据区。
循环定时时长到来之后，数据区管理模块60先到数据区队列中查找第一个数据区，然后判断该第一个数据区中的数据是否有效(为了应对程序异常的处理措施，防止该第一个数据区中的数据写错了或是空的情况，以提高程序的可靠性)，并判断该第一个数据区是不是数据区队列中的最后一个数据区。如果该数据区中的数据是有效的数据区，则根据该第一个数据区中记录的对应主叫端或者被叫端的IP地址和端口号，以及语音媒体报文的编解码格式、语音媒体报文的PT值、语音媒体报文的帧数组织语音媒体报文，语音媒体报文组织好之后根据数据区记载的呼叫端或者被叫端的IP地址和端口号向被验证系统发送语音媒体报文，接着查找当前数据区队列中的下一个数据区，判断该数据区中的数据是否有效，并且判断该数据区是否是数据区队列的最后一个，若该数据区是数据区对别中的最后一个，则发送完对应该数据区的语音媒体报文之后停止在当前数据区队列中的遍历，等待下一次循环定时时长的到来，再 从数据区队列中的第一个数据区开始发送一遍语音媒体报文。
第十四实施例
