本发明涉及通信测试技术领域，具体涉及一种语音专线自动拨测系统及方法。The invention relates to the technical field of communication testing, in particular to a system and method for automatic dialing and testing of dedicated voice lines.
背景技术Background technique
随着无线网络技术的不断发展和网络组建普及，客户对网络整体语音服务质量的要求不断提高，可以说，电话的接通率和语音质量的好坏直接影响着用户对于运营商的选择。因此，根据移动通信网络服务质量的要求，建立一套语音质量与通话测试的客观评价系统，来更好的对网络语音服务质量进行定量分析和评估，就逐步成为移动网络运营商在网络建设过程中必须考虑的关键问题。With the continuous development of wireless network technology and the popularization of network construction, customers' requirements for the overall voice service quality of the network continue to increase. It can be said that the call connection rate and voice quality directly affect the user's choice of operators. Therefore, according to the requirements of mobile communication network service quality, establishing a set of objective evaluation system for voice quality and call test to better quantitatively analyze and evaluate the network voice service quality will gradually become an important part of the network construction process for mobile network operators. key issues that must be considered.
拨打测试是各电信运营商普遍使用的检查网络运行状况和网络服务质量的基本方法。拨打测试的有效性和实用性不可替代。现有的人工拨测的方式不仅耗费人力，而且效率十分低，统计也非常困难，并且存在以下缺点：Dial-up test is a basic method commonly used by various telecom operators to check network operation status and network service quality. There is no substitute for the effectiveness and usefulness of a dial-in test. The existing manual testing method is not only labor-intensive, but also very inefficient and difficult to count, and has the following disadvantages:
1.人工拨测只能限于少量的、简单的测试，很难实现大话务量的、复杂的测试；1. Manual testing can only be limited to a small number of simple tests, and it is difficult to implement complex tests with large traffic volumes;
2.拨测的次数有限、任务类型有限、记录有用的信息少；2. The number of dial-up tests is limited, the types of tasks are limited, and there is little useful information recorded;
3.随意性大，数据准确性和可靠性差；3. Large randomness, poor data accuracy and reliability;
4.很难与其他技术手段结合，无法实现问题定位；4. It is difficult to combine with other technical means, and it is impossible to locate the problem;
5.统计困难，反馈时间长，很难快速反应测试结果。5. Statistics are difficult, feedback time is long, and it is difficult to quickly respond to test results.
目前的拨测系统中，对于语音测试往往采用将本地的音频文件发送到拨测终端，由拨测终端进行录音，然后再由拨测终端将录音返回给测试系统进行对比分析，但是这种方式很明显对测试结果有着很大影响，例如：拨测终端的录音设备的录音效果不理想，导致录音文件与本地音频文件存在着较大差别影响测试结果；发送本地音频文件至拨测终端需要更多的时间，占用通道资源多；而且本地音频文件在发送的过程中遇到通道异常的概率会随着发送音频文件的时间增加而增加，对此也会影响到拨测效率和拨测质量。In the current dial-up test system, for voice testing, local audio files are often sent to the dial-up test terminal, the dial-up test terminal records, and then the dial-up test terminal returns the recording to the test system for comparison and analysis, but this method Obviously, it has a great impact on the test results. For example: the recording effect of the recording device of the dial-up test terminal is not ideal, resulting in a large difference between the recording file and the local audio file, which affects the test results; More time will take up more channel resources; and the probability of encountering channel exceptions during the sending of local audio files will increase as the time for sending audio files increases, which will also affect the efficiency and quality of dial-up testing.

在测试之前，需要制作一段音频文件存储在本发明实施例中的自动拨测系统中的拨测单元内，拨测单元具有存储器，能够存储该音频文件（本地音频文件）以供中央处理单元调取分析，同时拨测单元内存储有客户的相关信息，包括：客户名称、客户级别、客户号码（通讯号码）、设备名称、设备类型等，均以供中央处理单元调取。同时，将该存储在系统本地的音频文件复制到拨测终端的存储单元，拨测终端的存储单元可以使用通用flash卡，便于将存储有系统本地音频文件的flash卡及时快速的安装到拨测终端并与控制器相连。Before the test, it is necessary to make a section of audio file and store it in the dial test unit in the automatic dial test system in the embodiment of the present invention. The dial test unit has a memory and can store the audio file (local audio file) for the central processing unit to call. At the same time, the relevant information of the customer is stored in the dial test unit, including: customer name, customer level, customer number (communication number), device name, device type, etc., all for the central processing unit to retrieve. At the same time, copy the audio files stored locally in the system to the storage unit of the dial test terminal. The storage unit of the dial test terminal can use a general-purpose flash card, which is convenient for timely and quickly installing the flash card storing the local audio files of the system to the dial test terminal. terminal and connected to the controller.
本发明实施例中的通讯单元用于与客户端设备建立通信，具体采用GSM卡作用通讯单元的核心元件。The communication unit in the embodiment of the present invention is used to establish communication with the client device, specifically, a GSM card is used as a core component of the communication unit.
在进行测试时，由中央处理单元调取拨测单元内的客户信息，此时调取的客户信息主要是存储在拨测单元内的客户名称、客户号码及任务类型（语音拨试或非语音拨测），然后由中央处理单元控制通讯单元呼叫拨测终端，由拨测终端的信息收发单元响应，当呼叫通道处于拨通状态时，如果任务类型是语音拨测任务，则服务器控制模块的中央处理单元发送控制信号触发拨测终端的控制器，控制器则将拨测终端事先存储的本地音频文件的复制件进行播放，并由信息收发单元将音频信号返回给自动拨测系统，中央处理单元将接收到的音频信号与本地的音频文件进行分析对比，得到语音拨测的结果；如果任务类型是非语音拨测，则中央处理单元在呼叫通道处于拨通状态时，会发送一个挂断信号给拨测终端，出发拨测终端的控制器自动挂断，从而实现对非语音拨测的接通率和掉话率的拨测。When testing, the central processing unit transfers the customer information in the dial test unit. At this time, the customer information transferred is mainly the customer name, customer number and task type (voice dial test or non-voice dial test) stored in the dial test unit. dial test), and then the central processing unit controls the communication unit to call the dial test terminal, and the information sending and receiving unit of the dial test terminal responds. When the call channel is in the dial through state, if the task type is a voice dial test task, the server control module The central processing unit sends a control signal to trigger the controller of the dial test terminal, and the controller plays the copy of the local audio file stored in advance by the dial test terminal, and the information sending and receiving unit returns the audio signal to the automatic dial test system, and the central processing The unit analyzes and compares the received audio signal with the local audio file to obtain the result of the voice dial test; if the task type is non-voice dial test, the central processing unit will send a hangup signal when the call channel is in the dial-through state For the dial testing terminal, the controller of the starting dial testing terminal automatically hangs up, so as to realize the dial testing of the connection rate and drop rate of non-voice dial testing.
本发明实施例中自动拨测系统的相关信息显示在显示单元，便于操作人员的查看和操作。In the embodiment of the present invention, relevant information of the automatic dialing and testing system is displayed on the display unit, which is convenient for operators to view and operate.
实施例2：Example 2:
本发明实施例基于上述实施例1中的自动拨测系统提供了一种语音专线自动拨测方法，如图2所示，包括如下步骤。The embodiment of the present invention provides an automatic dial-up and test method for a dedicated voice line based on the automatic dial-test system in Embodiment 1 above, as shown in FIG. 2 , including the following steps.
步骤101：获取拨测单元内的拨测任务信息，所述拨测任务信息包括客户名称、客户号码和任务类型。Step 101: Obtain the dial test task information in the dial test unit, the dial test task information includes customer name, customer number and task type.
本步骤中拨测任务信息的任务类型分为语音拨测任务和非语音拨测任务；作为一种优选方式，拨测任务信息还可以包括客户级别和设备类型；系统可以根据客户级别执行不同的拨测任务，例如，高级别的客户可以直接分配语音拨测任务，低级别的用户可以直接分配非语音拨测任务；对于客户的级别设定是由操作人员根据业务数据进行设定的，从而也有利于对客户资源进行管理。而拨测任务信息中包含设备类型是为了便于对设备类型的统计，显示单元中可以显示客户端的设备类型，从而对某些设备是否容易出错做出统计。In this step, the task type of the dial test task information is divided into a voice dial test task and a non-voice dial test task; as a preferred method, the dial test task information can also include customer level and device type; the system can perform different tasks according to the customer level Dial test tasks, for example, high-level customers can directly assign voice dial test tasks, and low-level users can directly assign non-voice dial test tasks; the level setting for customers is set by the operator according to business data, so that It is also conducive to the management of customer resources. The purpose of including the device type in the dial test task information is to facilitate the statistics of the device type. The display unit can display the device type of the client, so as to make statistics on whether some devices are prone to errors.
可以理解的是，在执行本步骤之前还可以对客户的信息进行初始化，例如针对此客户上次拨测的结果进行初始化，从而为本次拨测任务做好准备。It can be understood that, before performing this step, the information of the customer may also be initialized, for example, initializing the result of the customer's last dial-up test, so as to prepare for this dial-up test task.
步骤102：初始化通讯单元，将通讯单元的通道状态设为空闲状态，并呼叫客户号码。Step 102: Initialize the communication unit, set the channel state of the communication unit to an idle state, and call the customer number.
可以理解的是，本步骤中主要是对整个自动拨测系统的呼叫通道进行初始化的操作，对于自动拨测系统用做拨打测试的通讯单元需要安装一张GSM语音卡，通过控制GSM语音卡的通道拨打、接听来达到测试的目的，一张GSM语音卡能有多个通道，需要对每个呼叫通道都做初始化设置，以保证呼叫客户号码前，呼叫通道时空闲的。It can be understood that, in this step, the call channel of the entire automatic dial test system is mainly initialized. For the automatic dial test system, a communication unit for dialing a test needs to be installed with a GSM voice card. By controlling the GSM voice card Channel dialing and answering are used to achieve the purpose of testing. A GSM voice card can have multiple channels, and each call channel needs to be initialized to ensure that the call channel is idle before calling the customer number.
对于具体的呼叫通道的初始化操作，可以参考以下示例，并可以理解此示例并不是唯一示例：For the initialization operation of the specific call channel, you can refer to the following example, and understand that this example is not the only example:
在执行拨打操作前需要对GSM语音卡执行初始化，调用DJSys_EnableCard(""，"PROMPT.INI")；接着需要对GSM语音卡的呼叫通道执行初始化，循环调用DJISDN_SetChnState(intnPCM,intnCHN,DialClass.CH_SET_FREE,0)将所有呼叫通道设置为空闲状态。参数说明：nPCM为GSM语音卡的插槽号、CHN为呼叫通道序号、CH_SET_FREE为呼叫通道状态(见通道状态定义)，通道状态和动作定义如下：Before performing the dialing operation, it is necessary to initialize the GSM voice card, call DJSys_EnableCard("", "PROMPT.INI"); then it is necessary to initialize the call channel of the GSM voice card, and call DJISDN_SetChnState(intnPCM,intnCHN,DialClass.CH_SET_FREE, 0) Set all call channels to idle state. Parameter description: nPCM is the slot number of the GSM voice card, CHN is the serial number of the call channel, CH_SET_FREE is the state of the call channel (see channel state definition), and the channel state and action are defined as follows:
通道状态定义：判断呼叫通道状态的操作是DJISDN_GetChnState(卡号，通道号)，其返回结果描述如下：Channel state definition: The operation to judge the call channel state is DJISDN_GetChnState(card number, channel number), and the return result is described as follows:
publicconstbyteCH_FREE=1;//空闲状态//publicconstbyteCH_FREE=1;//idle state//
publicconstbyteCH_WAIT_APP_FREE=2;//DLL等待应用层同步释放资源publicconstbyteCH_WAIT_APP_FREE=2;//DLL waits for the application layer to release resources synchronously
publicconstbyteCH_UNAVIABLE=3;//不可用态(网络不通等原因导致)publicconstbyteCH_UNAVIABLE=3;//unavailable state (caused by reasons such as network failure)
publicconstbyteCH_WAIT_CONNECT_ACK=4;//等待连接证实publicconstbyteCH_WAIT_CONNECT_ACK=4;//Waiting for connection confirmation
publicconstbyteCH_CONNECT=5;//连通状态publicconstbyteCH_CONNECT=5;//connection status
publicconstbyteCH_WAIT_RELEASE=6;//已发送拆线信号，等待对方发送释放信号publicconstbyteCH_WAIT_RELEASE=6;//The disconnection signal has been sent, waiting for the other party to send a release signal
publicconstbyteCH_WAIT_RELEASE_COMPLETE=7;//已发送释放信号，等待对方发送释放证实信号publicconstbyteCH_WAIT_RELEASE_COMPLETE=7;//The release signal has been sent, waiting for the other party to send the release confirmation signal
publicconstbyteCALLEE_WAIT_ANSWER=11;//来话方呼叫到达publicconstbyteCALLEE_WAIT_ANSWER=11;//The incoming call arrives
publicconstbyteCALLER_WAIT_ANSWER=12;//去话方已呼出，等待被叫回应publicconstbyteCALLER_WAIT_ANSWER=12;//The outgoing party has dialed out, waiting for the called party to respond
publicconstbyteCALLER_RECV_ALERT=21;//去话方已接收到提醒消息publicconstbyteCALLER_RECV_ALERT=21;//The outgoing party has received the reminder message
publicconstbyteCALLER_RECV_SETUP_ACK=22;//去话方已接收到建立确认消息publicconstbyteCALLER_RECV_SETUP_ACK=22;//The outgoing party has received the establishment confirmation message
publicconstbyteCALLER_RECV_CALLPROCESS=23;//去话方已接收到呼叫过程消息publicconstbyteCALLER_RECV_CALLPROCESS=23;//The outgoing party has received the call process message
publicconstbyteCALLER_WAIT_SETUP_ACK=24;publicconstbyteCALLER_WAIT_SETUP_ACK=24;
通道动作定义：通过控制语音卡的呼叫通道状态来实现拨打测试的挂断、接听、设置为空闲等操作，用DJISDN_SetChnState(卡号，通道号，Action)设置，具体定义如下：Channel Action Definition: By controlling the call channel state of the voice card, the operations such as hanging up, answering, and setting as idle for dialing and testing are realized. Use DJISDN_SetChnState (card number, channel number, Action) to set, and the specific definitions are as follows:
publicconstbyteCH_SET_FREE=1;//APP层检查通道状态为OxO2时，同步释放呼叫通道资源publicconstbyteCH_SET_FREE=1;//When the APP layer checks that the channel status is OxO2, it releases the call channel resources synchronously
publicconstbyteCH_SET_CONNECT=2;//设置呼叫通道连接publicconstbyteCH_SET_CONNECT=2;//Set call channel connection
publicconstbyteCH_SET_DISCONNECT=3;//解除呼叫通道连接publicconstbyteCH_SET_DISCONNECT=3;//Release call channel connection
publicconstbyteCALLEE_SET_ALERTING=4;//被叫方发送提醒消息publicconstbyteCALLEE_SET_ALERTING=4;//The called party sends an alert message
publicconstbyteCH_SET_RESTART=5;//设置呼叫通道重新启动publicconstbyteCH_SET_RESTART=5;//Set the call channel to restart
将GSM语音卡和GSM语音卡的所有呼叫通道都初始化后，循环选取呼叫通道执行呼叫动作，即执行DJISDN_Callout(intnPCM,intnCHN,stringszCalleeNumber,stringszCalleeSubAddr,stringszCallerNumber,stringszCallerSubAddr)，参数说明：nPCM为GSM语音卡插槽号、nCHN为通道序列号、szCalleeNumber为主叫号码、szCallerNumber为被叫号码，其他参数可省略。After initializing the GSM voice card and all call channels of the GSM voice card, select the call channel in a loop to execute the call action, that is, execute DJISDN_Callout(intnPCM, intnCHN, stringszCalleeNumber, stringszCalleeSubAddr, stringszCallerNumber, stringszCallerSubAddr), parameter description: nPCM is the GSM voice card The slot number, nCHN is the channel serial number, szCalleeNumber is the calling number, szCallerNumber is the called number, other parameters can be omitted.
由此可见，本发明实施例中在呼叫通道初始化并呼叫客户的步骤中，采用了多呼叫通道的方式，并且循环选取呼叫通道对客户号码进行呼叫，从而增加了拨测的效率。It can be seen that, in the step of initializing the call channel and calling the customer in the embodiment of the present invention, multiple call channels are adopted, and the call channel is selected cyclically to call the customer number, thereby increasing the efficiency of dialing and testing.
为了对呼叫次数进行统计，本发明实施例中在执行呼叫客户的动作时还会再执行一个步骤109：对呼叫次数加1生成呼叫次数记录并保存。可以理解的是，呼叫次数可以作为操作对象进行定义，然后每次执行呼叫客户的动作时，对呼叫次数这一对象进行加1即可，并生成一个呼叫次数记录并保存，以便于测试者的查看和统计。In order to count the number of calls, in the embodiment of the present invention, another step 109 is executed when the action of calling the customer is performed: adding 1 to the number of calls to generate a record of the number of calls and saving it. It can be understood that the number of calls can be defined as an operation object, and then every time the action of calling the customer is executed, the object of the number of calls can be added by 1, and a record of the number of calls can be generated and saved for the convenience of the tester. View and statistics.
步骤103：判断呼叫通道状态是否为接通状态。Step 103: Judging whether the state of the calling channel is connected.
本步骤中通过判断通道状态来确定通道的呼叫动作执行后，被叫号码（即客户端处的拨测终端）是否接听。例如本发明实施例中在判断时通过调用DJISDN_GetChnState(intnPCM,intnCHN)，参数说明：nPCM为GSM语音卡插槽号、nCHN为通道序列号。如果返回结果为CH_CONNECT表示通话接通(此处函数命名及参数定义仅为示例，并不理解为对本发明思想的限制)。In this step, the channel state is judged to determine whether the called number (that is, the dial test terminal at the client terminal) is answered after the call action of the channel is executed. For example, in the embodiment of the present invention, DJISDN_GetChnState (intnPCM, intnCHN) is called when judging, parameter description: nPCM is the slot number of the GSM voice card, and nCHN is the channel serial number. If the returned result is CH_CONNECT, it means that the call is connected (the function naming and parameter definition here are only examples, and should not be understood as limitations to the idea of the present invention).
在确定呼叫通道状态为接通状态时，则表示被叫号码（拨测终端）已经接听，为了能够对接通率进行及时和准确的统计，在本发明实施例中一旦判断出呼叫通道的状态为接通状态，则会同时执行接通率统计的步骤，即步骤110：对接通次数加1生成接通次数记录并保存。同样可以理解的是，接通次数可以作为操作对象进行定义，然后在拨测终端接听呼叫时，对接通次数这一对象进行加1即可，并生成一个接通次数记录并保存，以便于测试者的查看和统计。When it is determined that the state of the call channel is connected, it means that the called number (dial test terminal) has answered. In order to make timely and accurate statistics on the connection rate, once the state of the call channel is judged In the connected state, the step of counting the connection rate will be executed at the same time, that is, step 110: add 1 to the connection times to generate a connection times record and save it. It can also be understood that the number of connection times can be defined as an operation object, and then when the dialing test terminal answers a call, the object of the number of connection times can be added by 1, and a record of the number of connection times can be generated and saved, so that Tester viewing and statistics.
在确定呼叫通道状态为接通状态时，还需要判断拨测任务类型是属于语音拨测还是非语音拨测，即执行步骤104：判断拨测任务是否为语音拨测任务。具体的判断依据则是根据步骤101中所获取的拨测任务类型。如果是语音拨测任务，则执行语音拨测步骤106。具体的语音拨测步骤将结合图3做出介绍：When determining that the state of the call channel is connected, it is also necessary to determine whether the dial test task type belongs to voice dial test or non-voice dial test, that is, perform step 104: determine whether the dial test task is a voice dial test task. The specific judgment basis is based on the dial test task type obtained in step 101 . If it is a voice dial test task, perform voice dial test step 106 . The specific voice dialing test steps will be introduced in conjunction with Figure 3:
步骤1061：发送一播音信号至拨测终端，触发拨测终端向呼叫通道播放音频文件。Step 1061: Send a broadcast signal to the dialing test terminal, triggering the dialing test terminal to play the audio file to the calling channel.
本步骤中播音信号为FSK格式信号，对应的十六进制编码为byte[]send=newbyte[]{0x04,0x09,0xB0,0x37,0x32,0xB0,0x31,0xB9,0xB3,0xB0,0x2A,0xB3}；接着将该播音信号在呼叫通道上发送。例如本发明实施例中对于该具体操作为DJFsk_SendFSK(trunkID,send,12,DialClass.FSK_CH_TYPE_E1)参数说明：trunkID为通道序列号、send为发送的十六进制数字编码，FSK_CH_TYPE_E1为信号类型。The broadcast signal in this step is an FSK format signal, and the corresponding hexadecimal code is byte[]send=newbyte[]{0x04,0x09,0xB0,0x37,0x32,0xB0,0x31,0xB9,0xB3,0xB0,0x2A,0xB3 }; Then send the broadcast signal on the calling channel. For example, in the embodiment of the present invention, the specific operation is DJFsk_SendFSK(trunkID, send, 12, DialClass.FSK_CH_TYPE_E1) parameter description: trunkID is the serial number of the channel, send is the hexadecimal digital code to send, and FSK_CH_TYPE_E1 is the signal type.
由于拨测终端上事先存储有系统本地的音频文件，因此拨测终端在接收到该播音信号后，会将该音频文件向呼叫通道播放，实现将拨测终端的音频文件返回给自动拨测系统的目的。Since the local audio files of the system are stored in the dial test terminal in advance, after receiving the broadcast signal, the dial test terminal will play the audio file to the call channel, so as to return the audio file of the dial test terminal to the automatic dial test system the goal of.
步骤1062：对呼叫通道内的音频文件进行录音生成音频录音文件。Step 1062: Record the audio file in the call channel to generate an audio recording file.
在步骤1061中拨测终端已经在呼叫通道上播放了音频文件，该音频文件的播放时长可以自行设置，例如本发明实施例中该音频文件的播放时长设置为15秒，拨测终端在呼叫通道播放15秒长的音乐，本自动拨测系统需要将该呼叫通道上的声音进行录音，以便于在后续步骤中与自动拨测系统本地存储的音频文件（原声文件）进行语音质量分析。例如本发明实施例中呼叫通道上录音的动作是DJVoc_RecordFile(inttrunkID,stringpathfile,8000*10)，参数pathfile=System.Configuration.ConfigurationSettings.AppSettings["path"]+Trunk[trunkID].CalleeNow+DateTime.Now.ToString("HHmmss")+GetRandmon()+trunkID.ToString()+".wav"，pathfile为文件保存的路径，录音格式为wav，文件命名格式为主叫号码+当前时间的时分秒毫秒、trunkID为通道序列号。In step 1061, the dial testing terminal has played the audio file on the call channel, and the playing time of the audio file can be set by itself. For example, in the embodiment of the present invention, the playing time of the audio file is set to 15 seconds. To play 15 seconds of music, the automatic dial test system needs to record the sound on the call channel, so as to conduct voice quality analysis with the audio file (original sound file) stored locally in the automatic dial test system in the subsequent steps. For example, the action of recording on the call channel in the embodiment of the present invention is DJVoc_RecordFile(inttrunkID, stringpathfile, 8000*10), parameter pathfile=System.Configuration.ConfigurationSettings.AppSettings["path"]+Trunk[trunkID].CalleeNow+DateTime.Now .ToString("HHmmss")+GetRandmon()+trunkID.ToString()+".wav", pathfile is the path to save the file, the recording format is wav, and the file naming format is the calling number + the hour, minute, second and millisecond of the current time, trunkID is the serial number of the tunnel.
为了在语音拨测过程中增加对掉话率的统计，本发明实施例中在步骤1062完成录音后，还增加了一个步骤1063：判断音频录音文件播放时长是否小于拨测终端的音频文件播放时长。如果音频录音文件播放时长小于了拨测终端的音频文件播放时长，则说明在录音过程中出现了掉话，导致整个音频文件没有录完，所以此时会执行步骤1066：生成掉话记录并保存。如果音频录音文件和拨测终端的音频文件的播放时长相同，则说明整个音频文件完全被录制，期间并未发生掉话现象，则进入到下一步骤1064：将音频录音文件与本地音频文件进行对比分析。在本发明实施例中采用PESQ（PerceptualEvaluationofSpeechQuality）方法对音频录音文件与本地音频文件进行分析对比，适用于固定网、移动网和VoIP网的网络评估，分析结果较为客观准确。In order to increase the statistics of the call drop rate in the voice dialing test process, after the recording is completed in step 1062 in the embodiment of the present invention, a step 1063 is added: judge whether the audio recording file playback duration is less than the audio file playback duration of the dialing test terminal . If the playing time of the audio recording file is shorter than the playing time of the audio file of the dialing test terminal, it means that there is a call drop during the recording process, resulting in the recording of the entire audio file, so step 1066 will be performed at this time: generate and save the call drop record . If the playing duration of the audio recording file and the audio file of the dialing test terminal are the same, it means that the entire audio file is completely recorded, and there is no call drop phenomenon during the period, then enter the next step 1064: compare the audio recording file with the local audio file Comparative analysis. In the embodiment of the present invention, PESQ (PerceptualEvaluationofSpeechQuality) method is used to analyze and compare audio recording files and local audio files, which is suitable for network evaluation of fixed network, mobile network and VoIP network, and the analysis results are more objective and accurate.
步骤1065：生成语音分析结果完成语音拨测任务并保存该分析结果。本步骤中采用PESQ方法生成的语音分析结果分为几个等级：优秀（很好，听的很清楚，延迟很小，交流流畅）、良好（稍差，听的清楚，延迟小，交流欠缺顺畅，有点杂音）、一般（还可以，听不太清，有一定延迟，可以交流）、差（勉强，听不太清，延迟较大，交流重复多次）、很差（极差，听不清，延迟大，交流不通畅）。Step 1065: Generate a voice analysis result to complete the voice dial test task and save the analysis result. The speech analysis results generated by the PESQ method in this step are divided into several grades: excellent (very good, very clear, small delay, smooth communication), good (slightly poor, clear hearing, small delay, lack of smooth communication) , a little noise), average (it’s okay, I can’t hear clearly, there is a certain delay, and I can communicate), poor (barely, I can’t hear clearly, the delay is large, and the communication is repeated many times), very poor (very poor, I can’t hear clear, the delay is large, and the communication is not smooth).
具体的非语音拨测步骤将结合图4做出介绍：The specific non-voice dialing test steps will be introduced in conjunction with Figure 4:
非语音拨测步骤相对于语音拨测步骤省去了音频文件分析对比的步骤，主要目的在于测试接通率和掉话率，因此，被叫号码接通后，只需要向拨测终端发送一个挂断信号，触发拨测终端自动挂断。即执行步骤1072：发送一挂断信号至拨测终端，触发拨测终端自动挂断。在此过程中未有异常出现，则生成非语音拨测记录，对此次非语音拨测未出现异常做出记录，即执行步骤1073：生成并保存非语音拨测记录。Compared with the voice dial test step, the non-voice dial test step omits the step of audio file analysis and comparison. The main purpose is to test the connection rate and call drop rate. Therefore, after the called number is connected, it only needs to send a call to the dial test terminal. Hang up signal, trigger the dial test terminal to hang up automatically. That is, step 1072 is executed: sending a hang up signal to the dial test terminal, triggering the dial test terminal to hang up automatically. If there is no abnormality in this process, a non-voice dial test record is generated, and a record is made if there is no abnormality in this non-voice dial test, that is, step 1073 is executed: generating and saving a non-voice dial test record.
为了在非语音拨测过程中增加对掉话率的统计，本发明实施例中在发送挂断信号之前还再次对通话的接通情况做出判断，即执行步骤1071：判断呼叫通道状态是否为接通状态。如果呼叫通道处于挂断状态，则证明此次呼叫出现了掉话，执行步骤1074：生成掉话记录并保存。如果呼叫通道处于接通状态，则证明此次呼叫未出现异常，继续执行步骤1072。In order to increase the statistics of the call drop rate in the non-voice dialing test process, before sending the hang up signal in the embodiment of the present invention, the connection situation of the call is judged again, that is, step 1071 is executed: judge whether the call channel state is connected state. If the call channel is in the hang-up state, it proves that the call has been dropped, and step 1074 is performed: generating and saving the call drop record. If the call channel is in the connected state, it proves that there is no abnormality in this call, and proceed to step 1072 .
在步骤102呼叫客户号码的过程中，可能会出现客户占线或者无法接通的情况，因此，如果步骤103中判断出呼叫通道状态未未接通状态时，则可以进行持续呼叫，但是如果无休止的持续呼叫会占用过多的系统资源，因此，本发明实施例中在步骤103判断出呼叫通道状态为非接通状态后，会再执行步骤105：判断呼叫通道连接是否超时。如果呼叫通道连接超时，则不需要持续呼叫，而是执行步骤108：生成并保存超时记录。该超时记录记录了该客户号码的呼叫超时情况，便于测试人员进行统计分析。呼叫超时后，则可以改换另一客户号码进行拨测。如果呼叫通道连接未超时，则返回步骤103再次判断呼叫是否成功接通，即允许在设定的时间范围内对该客户号码进行持续呼叫，直至呼叫接通（即呼叫通道处于接通状态）。In the process of calling the customer number in step 102, it may occur that the customer is busy or cannot be connected. Therefore, if it is judged in step 103 that the call channel status is not connected, the continuous call can be made, but if there is an endless The continuous calls will take up too many system resources. Therefore, in the embodiment of the present invention, after judging that the call channel state is not connected in step 103, step 105 will be executed again: determine whether the call channel connection has timed out. If the call channel connection times out, the call does not need to be continued, but step 108 is performed: generating and saving the timeout record. The timeout record records the call timeout situation of the customer number, which is convenient for testers to carry out statistical analysis. After the call times out, you can change another customer number for dialing test. If the call channel connection is not overtime, then return to step 103 to judge whether the call is successfully connected again, that is, to allow continuous calls to the customer number within the set time frame until the call is connected (that is, the call channel is in the connected state).
由本发明实施例的技术方案可以看出，该自动拨测方法设有语音拨测和非语音拨测两种方式可供选择，增加了拨测的灵活性，测试者可以选择在忙时（例如8点至10点、18点至20点）进行非语音拨测，以便于提高拨测效率；可以选择在非忙时进行语音拨测，以保证高级别客户的拨测质量。对于语音拨测和非语音拨测都增加了掉话率和接通率的统计，实现了拨测结果的全面性。As can be seen from the technical solutions of the embodiments of the present invention, the automatic dial test method is provided with two modes of voice dial test and non-voice dial test to choose from, which increases the flexibility of dial test, and the tester can choose when he is busy (such as 8:00 to 10:00, 18:00 to 20:00) to conduct non-voice dialing test to improve the efficiency of dialing test; you can choose to perform voice dialing test during non-busy hours to ensure the quality of dialing test for high-level customers. The statistics of call drop rate and connection rate are added for both voice dial test and non-voice dial test, which realizes the comprehensiveness of dial test results.
