具体实施方式
为使本发明要解决的技术问题、技术方案和优点更加清楚，下面将结合附图及具体实施例进行详细描述。
现有技术中目前存在的问题有以下：
1)商用话务模拟工具还不支持集群功能，无法进行相应的集群业务测试支持；
2)真实UE(user equipment，用户终端)话务，由于数量有限，并且测试控制往往需要人为干预，很难实施，同时价格也比较贵。这种数量有限的真实UE无法达到信令业务和数据业务的极限测试。此外，因为由真实UE实现的话务测试的流程依赖于软件流程，比如反复开关机，反复进行话权申请操作等，所以其对定制业务流程的测试支持不足，不便于测试业务的扩展；
3)LTE商用模拟工具仅能进行LTE测试，不能用于集群话务测试。
总而言之，目前采用真实终端作为话务终端，还有一些也采用商用的 话务模拟仪，没法实现集成话务测试。
本发明实施例提供一种模拟测试方法、装置及业务模拟器、计算机存储介质，通过自定义方式提供多种功能，并且实现集成话务测试，可以完成模拟大量UE的呼叫流程，能够准确地获取接入网的话务处理能力指标。
如图1所示，本发明实施例提供一种模拟测试方法中，包括：
步骤11，获取宽度集群***中的测试指令后，封装并发送业务请求消息；
步骤12，根据所述业务请求消息，生成上行空口数据并发送给接入网；
步骤13，接收由所述接入网针对所述上行空口数据触发的下行空口数据，进行解码并确认与所述接入网建立的空口连接；
步骤14，根据建立的所述空口连接，触发生成业务数据进行测试。
在上述步骤11至步骤14中，通过在宽度集群***中，自定义协议内容如自定义的所述业务请求消息来扩展多种业务，同时通过建立与接入网之间的空口连接，触发生成业务数据进行测试，因此实现了测试工具和接入网的业务测试可根据模型设置进行，节省了大量测试时间，提高了测试效率，从而满足相应产品的测试工作中的大话务测试的要求。
需要说明的是：所述空口连接包括下行共享信道连接以及RCC(Radio Resource Control，无线资源控制协议)连接的一种或多种。
另外，自定义的所述业务请求消息包括完成登记业务、注销业务、组信息更新业务、全双工单呼业务、半双工单呼业务、语音组呼业务、视频组呼业务、短消息业务、短数据业务、话权申请业务、话权排队业务、话权释放业务中的一种或多种。
还有，所述业务数据包括语音数据、视频流数据、短消息数据及传输控制协议/因特网互联协议TCP/IP数据中的一种或多种。也就是说，所述业务请求消息是指具有定义的这些功能，而针对具体测试的项目，是通过业 务请求消息携带的具体的测试内容来决定，从而发起连接，这样在建立连接后，然后将具体的测试内容进行传输，所述业务数据就是具体的测试内容。为了能够将测试的内容进行传输，本发明实施例的模拟测试方法中，所述步骤14包括：
步骤141，发送所述业务请求消息给核心网进行话权申请；
步骤142，获取所述核心网根据所述业务请求消息返回的话务确认消息；
步骤143，在返回所述话务确认消息之后，触发生成所述语音数据发送给所述核心网；
步骤144，接收所述核心网转发的所述语音数据。
本发明的另一实施例是：在所述步骤142之后，还可以是触发生成所述视频流数据发送给所述核心网；然后再接收所述核心网转发的所述视频流数据，具体和所述业务请求消息的请求内容有关。
需要说明的是：步骤143，将生成的语音数据发送给核心网后，通过核心网将所述语音数据发送给集群***中的其他用户(其他听用户)，然后步骤144接收由所述核心网通过下行共享信道发送其他用户的语音数据，通过这样发送与接收，完成整个测试的过程。
本发明实施例的具体实现流程举例如下。
如图2所示，步骤21：收到开始业务测试，发起业务请求建立，其中还有部分用户是通过寻呼触发下行共享信道建立；
步骤22：此时与接入网没有RRC连接，与接入网E-NodeB(演进节点B)发起RA(request Access，请求接入)随机接入流程；
步骤23：与接入网E-NodeB开始建立RRC连接后，建立专有业务承载，该专有业务承载用于承载专有业务数据；
步骤24：专用承载建立后，进行具体的话权申请、话权排队、话权释 放等操作测试(和发起业务请求过程一样)；其中针对话权申请，核心网将判断要不要给用户话权，具体的话权确认，不仅需要NAS层的专用承载即在核心网与UE之间建立一个虚拟通道，而且需要RCC即需要在UE和核心网之间建立一个虚拟通道；
步骤25：在测试完成后，进入释放专用承载连接；
步骤26：根据需要上报测试结果数据，然后结束本轮测试。
由于一个终端可以属于多个组群，如果都在同时建立测试时，需要进行优先级别的判别，因此本发明实施例的模拟测试方法中，在步骤11之后还包括：
步骤15，获取核心网针对所述业务请求消息中所在群组的优先级别返回的响应消息。
需要说明的是：本方案可以应用于终端，也可以应用于业务模拟器，其中业务模拟器可以仿真大量的终端，这些终端可以配置号码，集群***PDS侧会提前给这些号码开相应的权限，并且会根据测试的需要划分成很多的组(组可以有很多用户，一个号码也可以放在多个组)，如果一个用户同时属于多个组，进行业务时的一个时刻只能在一个优先级高的组。
在做组呼业务时，一般都是由主叫UE发起业务，被叫是通过相应基站E-NodeB集群寻呼信道的寻呼消息连接上基站E-NodeB；调度台也可以发起组的创建，此时，其它用户在一开始的时候，都属于被叫(非话权用户)，这些用户可以进行相应话权申请业务，变为话权用户(主叫用户)进行说话/视频流的发送，其它用户就是接收这些业务数据。
如图3中所示，PDS和E-NodeB的连接只有下行箭头，这是B-Trunc集群的下行共享连接，只有下行共享的业务(比如下行组呼音频流业务)才走这个连接。
本发明整个语音呼叫业务的流程举例如下。
步骤31，主叫用户发起语音组呼业务请求，此时，目前无RRC连接，此时就会和基站进行交互以创建空口的RRC连接，在连接创建的过程中，也把组呼业务请求通过基站发给了PDS，PDS第一步就是要求基站和主叫用户建立专用承载，此承载用于NAS信令交互和语音流数据的传送。
步骤32，专用承载建立的过程中，PDS发现是用户要求建立组，PDS就会构造寻呼消息发给相应的基站(可能是多个基站)，基站就会通过集群寻呼信道寻呼这个组里其它的用户，这些被叫用户收到这些寻呼消息，就会在后续流程中和基站创建下行共享信道，用于接收相应的NAS信令和语音数据，这样被叫用户就能听到主叫的声音了。另外主叫用户建立好专用承载后会收到PDS发过来的话权确认消息，如果下行共享也建立好了，就会收到振铃消息，此时，主叫/话权用户就可以说话了。
步骤33，主叫如果发起话权释放，主叫用户就自然进入到听(被叫)用户，其它用户可以通过话权申请变为主叫用户，在申请话权时，如果没有RRC连接，就要重复步骤31的RRC连接建立过程。
步骤34，长时间无话权用户和组里的用户可以触发组释放流程。
相应的，如图4所示，本发明实施例的一种模拟测试装置，应用于业务模拟器，所述模拟测试装置包括：
非接入层NAS协议模块41，配置为获取宽度集群***中的测试指令后，封装并发送业务请求消息；
第一空口协议模块42，配置为根据所述业务请求消息，生成上行空口数据并发送给接入网；
第二空口协议模块43，配置为接收由所述接入网针对所述上行空口数据触发的下行空口数据，进行解码并确认与所述接入网建立的空口连接；
数据源模块44，配置为根据建立的所述空口连接，触发生成业务数据进行测试。
本发明实施例中，通过在宽度集群***中，自定义协议内容来扩展多种业务，同时通过建立与接入网之间的空口连接，触发生成业务数据进行测试，因此实现了测试工具和接入网的业务测试可根据模型设置进行，节省了大量测试时间，提高了测试效率，从而满足相应产品的测试工作中的大话务测试的要求。
需要说明的是：所述空口连接包括下行共享信道连接以及RCC(Radio Resource Control，无线资源控制协议)连接的一种或多种。
另外，上述NAS协议模块41自定义的主要内容有：完成登记、注销、组信息更新、全双工单呼(有应答半双工单呼)、半双工单呼、语音组呼和视频组呼、短消息和短数据、话权申请、话权排队、话权释放等业务的信令模拟仿真。相较于传统的LTE来说，本发明实施例的NAS协议模块41控制的面比较多，如语音或视频等，可以根据配置参数生成相应业务请求报文，处理响应报文，并能持续地完成后续的测试业务流程。
上述数据源模块44的主要内容有：配合NAS协议模块41，在业务信令流程完成后进行语音、视频流、短消息及IP/TCP数据的生成，其中本发明实施例的数据源模块44也是为了配合NAS协议模块41的改进，来相应改进对应NAS协议模块41的部分，在信令流程已经准备好后，会生成相应的数据报文交由空口协议层处理，并处理下层送上来的数据。
还有，上述第一空口协议模块42及所述第二空口协议模块43可以统称为空口协议模块4，用于空口链路维护和上下行报文处理，具体的说就是接收处理接入网的下行空口数据，下行空口数据经解码后分发给相应的NAS协议模块41和数据源模块44；封装NAS协议模块41产生的信令和数据源，生成相应的上行空口数据发给接入网(根据NAS协议模块41或数据源模块44的需要进行空口建立及释放维护，并接收处理由接入网、NAS协议模块41或数据源模块44发送的报文)。
在实际应用中，所述NAS协议模块41、第一空口协议模块42、第二空口协议模块43、数据源模块44均可由中央处理单元(CPU，Central Processing Unit)、或数字信号处理(DSP，Digital Signal Processor)、或微处理器(MPU，Micro Processor Unit)、或现场可编程门阵列(FPGA，Field Programmable Gate Array)等来实现。
本发明实施例的模块之间的实现流程如下。
步骤51，业务模拟器收到控制台的开始测试指令。
步骤52，业务模拟器根据指令设置话务测试的业务类型及话务模型参数，调用模拟UE实体进行相应的业务测试流程，NAS协议模块41构造并封装业务请求消息，其中所述业务请求消息中携带有相应的上述NAS协议模块41定义的内容；
步骤53，该消息发送到空口协议模块进行相应空口协议处理生成空口报文发送给接入网，其中，所述接入网针对所述业务请求消息进行响应；
步骤54，接入网收到业务请求消息后，会触发后续下行响应消息给业务模拟器，业务模拟器先经过空口协议模块的处理再进行编解码的处理，并把处理后的消息分发给NAS协议模块41处理；
步骤55，若NAS协议模块41的LTE(LTE是维护承载成本)确认承载已经建立，便会触发数据源模块44进行业务数据的生成发送相应的上行数据报文，该上行报文发送给空口协议模块4进行封装发送，数据源模块44还需要接收处理经空口解码后的业务数据报文(生成语音报文或视频报文，生成这些内容就完成测试了)；
步骤56，业务测试完成后，数据源模块44停止业务数据的发送，NAS协议模块41和空口协议模块也会触发相应释放流程，完成此次的业务测试。
本发明的又一实施例的模拟测试装置中，所述业务请求消息包括完成登记业务、注销业务、组信息更新业务、全双工单呼业务、半双工单呼业 务、语音组呼业务、视频组呼业务、短消息业务、短数据业务、话权申请业务、话权排队业务、话权释放业务中的一种或多种。
本发明的又一实施例的模拟测试装置中，所述业务数据包括语音数据、视频流数据、短消息数据及传输控制协议/因特网互联协议TCP/IP数据中的一种或多种。
本发明的又一实施例的模拟测试装置中，
所述NAS协议模块41，还配置为发送所述业务请求消息给核心网进行话权申请；获取所述核心网根据所述业务请求消息返回的话务确认消息；
所述数据源模块44，还配置为在NAS协议模块41接收到话务确认消息之后，触发生成所述语音数据发送给所述核心网；接收所述核心网转发的所述语音数据。
需要说明的是：发送“话权申请”和接收“话权确认”是NAS协议模块41处理的。NAS协议模块41在话权申请时，数据源模块44需要作好语音数据业务发送前的初始化，转为发送态(初始)，而没有话权申请的听用户的数据源模块44是处于接收态，当NAS协议模块41接收到话权确认时，通知数据源模块44，进入数据源模块44(发送语音态)直接发送语音数据；NAS协议模块41进行话权释放时，会发信令给核心网，同时通知数据源模块44，数据源模块44停止发送语音，数据源模块44又进入了接收态(或者是被叫态)。
本发明的另一实施例，所述数据源模块44包括：触发单元，还配置为触发生成所述视频流数据发送给所述核心网；
接收单元，还配置为接收所述核心网转发的所述视频流数据。
需要说明的是：触发子模块将生成的语音数据发送给核心网后，通过核心网将所述语音数据发送给集群***中的其他用户(其他听用户)，然后接收单元接收由所述核心网通过下行共享信道发送其他用户的语音数据， 通过这样发送与接收，完成整个测试的过程。
本发明实施例可以在测试过程中，会故意发一些错误指令，可以查看***的处理情况，即可以很简单的实现定制流程测试及异常信令、异常流程的测试，提升被测***的稳定性，同时本发明实施例的接入跨过了无线，UE可以轻松在多个小区间切换，没有无线的干扰，方便***问题的排查和定位，加快业务***稳定。
需要说明的是：对于将语音数据发送给核心网，可以是通过一个通信模块502实现，可以是模拟测试装置的模块，也可以是借助外界通信模块进行发送。
本发明实施例的具体实现流程举例如下。
步骤61：收到开始业务测试，UE(业务模拟器模拟的用户终端或终端，均称为用户终端UE)的NAS协议模块41发起业务请求建立，其中还有部分用户是通过寻呼触发下行共享信道建立；
步骤62：此时空口协议模块4无RRC连接，空口协议模块4与接入网E-NodeB发起RA随机接入流程；
步骤63：UE与接入网E-NodeB开始建立RRC连接后，建立专有业务承载(NAS协议模块41)，用于承载专有业务数据；
步骤64：专用承载建立后，UE开始进行NAS协议模块41具体的话权申请、话权排队、话权释放等操作测试(和发起业务请求的过程一样)；其中针对话权申请，核心网会判断要不要给用户话权，具体的话权确认，不仅需要NAS层的专用承载，而且还需要有RCC；
步骤65：在测试完成后，进入释放专用承载连接；
步骤66：根据需要上报测试结果数据，然后结束本轮测试。
本发明实施例的模块之间的通信流程如下。
如图5所示，上述通信模块502有两种功能：一个是建立与控制后台 的通讯连接，把从控制后台收到的执行指令或消息交给业务控制模块501，完成测试业务模型设置，并出发测试业务流程；另一个是和E-NodeB建立通讯，收发与其的下上行报文。其中业务控制模块501接收到控制后台的用例执行指令，交由NAS协议模块41编码成业务请求报文，再经过空口协议模块4封装，并通过通信模块502发送给接入网(E-NodeB)；从接入网(E-NodeB)发来的下行消息由通信模块502接收，并把接收的下行空口报文，交由空口协议模块4来空口解码处理，空口解码后的数据，若是NAS消息则交给NAS协议模块41处理，若是数据则交给数据源模块44做解码和后续的处理，并把数据统计结果交给业务控制模块501。
通过上述过程可以实现，在极限负荷测试中，在一个配置了12个小区E-NodeB下，使用仿真2000部UE进行附着去附着测试；1000组反复单呼测试；1000组反复语音组呼业务测试；250组视频组呼业务。
本发明的又一实施例的模拟测试装置还包括：
获取模块，配置为获取核心网针对所述业务请求消息中所在群组的优先级别返回的响应消息。
本发明实施例的语音组呼业务流程的描述如下。
步骤71，主叫用户通过NAS协议模块41发起语音组呼业务请求，此时，在向空口协议模块4发现空口目前无RRC连接，此时就会和基站进行创建空口的RRC连接，在连接创建的过程中，也把组呼业务请求通过基站发给了PDS，PDS第一步就是要求基站和主叫用户建立专用承载，此承载用于NAS信令交互和语音流数据的传送。
步骤72，专用承载建立的过程中，PDS发现是用户要求建立组，PDS就会构造寻呼消息发给相应的基站(可能是多个基站)，基站就会通过集群寻呼信道寻呼这个组里其它的用户，这些被叫用户收到这些寻呼消息，就会在后续流程中和基站创建下行共享信道，用于接收相应的NAS信令和语 音数据，这样被叫用户就能听到主叫的声音了。另外主叫用户建立好专用承载后会收到PDS发过来的话权确认消息，如果下行共享也建立好了，就会收到振铃消息，此时，主叫/话权用户就可以说话了。
步骤73，主叫如果发起话权释放，主叫用户就自然进入到听(被叫)用户，其它用户可以通过话权申请变为主叫用户，在申请话权时，如果没有RRC连接，就要重复1种RRC连接建立过程。
步骤74，长时间无话权用户和组里的用户可以触发组释放流程。
需要说明的是，本发明提供的装置是应用上述模拟测试方法的装置，则上述模拟测试方法的所有实施例均适用于该装置，且均能达到相同或相似的有益效果。

所述的业务模拟器可以和被测设备E-NodeB设备一对一或多对一的关系进行相连。如图6所示，从图6中可以看出，大话务量测试***包括控制后台601、业务模拟器602/604/605/606/608、接入网(E-NodeB)603/607/609、核心网(EPC and DSS)610和调度台(DAS)611。其中，控制后台601与业务模拟器602/604/605/606/608按一对多的方式通过以太网进行连接，业务模拟器602/604/605/606/608与基站收发信机(BTS)603/607/609按一对一或多对一的方式通过以太网进行连接，接入网(E-NodeB)603/605/607/609与核心网610按多对一的方式通过以太网进行连接，核心网610按一对一的方式通过以太网调度台611相连。业务模拟器602/604/605/606/608组成业务模拟器组，由控制后台601统一控制。控 制后台601根据用户使用的配置参数发出开始和停止测试命令消息到业务模拟器602/604/605/606/608，来实现对各业务模拟器的模拟UE控制，并产生测试报告结果。
相应的由于本发明实施例的模拟测试装置，应用于业务模拟器，因此，本发明实施例还提供了一种业务模拟器，其中，上述模拟测试装置的所述实现实施例均适用于该业务模拟器的实施例中，也能达到相同的技术效果。
以上所述是本发明的优选实施方式，应当指出，对于本技术领域的普通技术人员来说，在不脱离本发明所述原理的前提下，还可以作出若干改进和润饰，这些改进和润饰也应视为本发明的保护范围。
