[0094] As shown in Figure 1, the present application provides a VoLTE complaint problem analysis method, which includes: Figure 1

[0095] Step 101: Acquire service domain data and operation domain data related to VoLTE complaint data.

[0096] Before step 101, the present application further includes:

[0097] ​Receiving VoLTE complaint data. The VoLTE complaint data includes complaint time information and complaint user information, which can be a complaint number, for example.

[0098] According to the complaint user information, service domain data and operation domain data related to the VoLTE complaint data can be obtained.

[0099] The service domain data can be obtained through a business operation support system (BOSS).

[0100] Optionally, the service domain data includes user subscription data.

[0101] Optionally, the operation domain data includes at least one of the following:

[0102] Signaling data, network optimization data, alarm data, MR data, resource data, and performance indicator data.

[0103] Step 102: performing boundary analysis according to the service domain data to determine a first VoLTE complaint problem corresponding to the VoLTE complaint data.

[0104] Step 103: in the case where the first VoLTE complaint problem does not belong to a user subscription problem, performing boundary analysis according to the operation domain data to determine a second VoLTE complaint problem corresponding to the VoLTE complaint data, and performing positioning analysis according to the operation domain data to determine a third VoLTE complaint problem corresponding to the VoLTE complaint data.

[0105] In this embodiment, first, boundary analysis is performed according to the service domain data, and in the case where the first VoLTE complaint problem corresponding to the VoLTE complaint data does not belong to a user subscription problem, boundary analysis and positioning analysis are performed according to the operation domain data to determine a second VoLTE complaint problem and a third VoLTE complaint problem corresponding to the VoLTE complaint data. In this way, the analysis of the VoLTE complaint problem not only includes positioning analysis but also boundary analysis, and the VoLTE complaint problem analysis is comprehensive, thereby improving the accuracy of VoLTE complaint problem analysis.

[0106] It can be understood that in the case where the first VoLTE complaint problem belongs to a user subscription problem, the steps of the VoLTE complaint problem analysis method can be ended.

[0107] Optionally, the boundary analysis includes at least one of the following:

[0108] Continuous call problem boundary analysis, voice quality problem boundary analysis, and performance indicator problem boundary analysis.

[0109] Optionally, the positioning analysis comprises at least one of:

[0110] Continuous call problem positioning analysis; voice quality problem positioning analysis; performance index problem positioning analysis.

[0111] It should be noted that the continuous call refers to a connection process.

[0112] Optionally, the second VoLTE complaint problem comprises at least one of:

[0113] Wireless problem; core network problem; terminal problem; user behavior problem.

[0114] It should be noted that the wireless problem refers to that A calls B and the call is connected, but the call between A and B is interrupted due to a wireless reason, which is a user plane problem.

[0115] In one embodiment, optionally, the service domain data comprises high-definition voice function subscription information, and step 102 comprises:

[0116] Performing delimiting analysis according to the high-definition voice function subscription information to determine the first VoLTE complaint problem corresponding to the VoLTE complaint data.

[0117] In this embodiment of the application, the delimiting analysis is performed according to the high-definition voice function subscription information to determine whether the VoLTE function corresponding to the VoLTE complaint data is normal, and if not, the delimiting result is obtained, that is, it is determined that the first VoLTE complaint problem corresponding to the VoLTE complaint data belongs to a user subscription problem, and the step of the VoLTE complaint problem analysis method is ended.

[0118] In one embodiment, optionally, in the case that the first VoLTE complaint problem does not belong to the user subscription problem, the method further comprises:

[0119] Performing positioning analysis according to the service domain data to determine a fourth VoLTE complaint problem corresponding to the VoLTE complaint data.

[0120] The fourth VoLTE complaint problem comprises at least one of:

[0121] User stop / restart problem; general packet radio service problem; access point problem.

[0122] In the embodiment of the present application, first, the high-definition voice function subscription information in the service domain data is analyzed to determine whether the VoLTE complaint data corresponds to a normal VoLTE function. If not, the delimiting result is obtained, that is, it is determined that the first VoLTE complaint problem corresponding to the VoLTE complaint data belongs to a user subscription problem, and the step of the VoLTE complaint problem analysis method is ended. If it is normal, further positioning analysis is performed according to the service domain data to obtain the positioning result, that is, it is determined that the fourth VoLTE complaint problem corresponding to the VoLTE complaint data can effectively avoid positioning of VoLTE complaint problems by non-VoLTE users, avoid interference with the delimiting result and the positioning result, thereby effectively reducing the analysis time of the operation and maintenance personnel and improving the processing efficiency of the VoLTE complaint problem.

[0123] In an embodiment, in step 103, the second VoLTE complaint problem corresponding to the VoLTE complaint data is determined by delimiting analysis according to the operation domain data, including:

[0124] The operation domain data is subjected to multiple delimiting analyses to obtain multiple first sub-complaint problems corresponding to the VoLTE complaint data.

[0125] The multiple first sub-complaint problems are input into a problem analysis model for analysis to obtain a second VoLTE complaint problem output by the problem analysis model. The problem analysis model is obtained by training a classification algorithm model using historical labeled data.

[0126] It can be understood that since the delimiting analysis includes at least one of the following: continuous call problem delimiting analysis, voice quality problem delimiting analysis, and performance index problem delimiting analysis, the operation domain data can be subjected to the above multiple delimiting analyses to achieve comprehensive analysis.

[0127] After multiple delimiting analyses, multiple first sub-complaint problems are obtained, wherein each delimiting analysis corresponds to a first sub-complaint problem. The multiple first sub-complaint problems are input into a problem analysis model, and the problem analysis model outputs a second VoLTE complaint problem.

[0128] The problem analysis model is obtained by training a classification algorithm model using historical labeled data. The historical labeled data relies on expert experience, and the classification algorithm model uses machine learning technology and belongs to the field of artificial intelligence, which can improve the accuracy of problem positioning. Therefore, the VoLTE complaint problem analysis method according to the embodiment of the present application combines expert experience and machine learning technology to input the first sub-complaint problems corresponding to multiple delimiting analyses to achieve comprehensive determination.

[0129] Suppose, the continuous call problem of the operation domain data is analyzed, the voice quality problem is analyzed, the performance index problem is analyzed, the three analysis is not in order, and the first sub-complaint problem corresponding to each analysis is obtained, then the three first sub-complaint problems are input into the problem analysis model, and the second VoLTE complaint problem is output by the problem analysis model.

[0130] In addition, in step 103: according to the positioning analysis of the operation domain data, the third VoLTE complaint problem corresponding to the VoLTE complaint data is determined, comprising:

[0131] The operation domain data is analyzed, and a plurality of third sub-complaint problems corresponding to the VoLTE complaint data are obtained;

[0132] The plurality of third sub-complaint problems are input into the problem analysis model for analysis, and the third VoLTE complaint problem output by the problem analysis model is obtained.

[0133] It can be understood that since the positioning analysis includes at least one of the following: continuous call problem positioning analysis; voice quality problem positioning analysis; performance index problem positioning analysis, the above-mentioned multiple positioning analysis of the operation domain data can be performed to achieve comprehensive analysis effect.

[0134] After the multiple positioning analysis, a plurality of third sub-complaint problems are obtained, wherein each analysis corresponds to a third sub-complaint problem. The plurality of third sub-complaint problems are input into the problem analysis model, and the third VoLTE complaint problem is output by the problem analysis model.

[0135] Of course, the plurality of first sub-complaint problems and the plurality of third sub-complaint problems can also be input into the problem analysis model for analysis at the same time, and the fifth complaint problem output by the problem analysis model is obtained, which combines the delimitation result and the positioning result to realize comprehensive determination.

[0136] As Figure 2 The flowchart of the VoLTE complaint problem analysis method is shown. According to the embodiment, the VoLTE complaint problem analysis method comprises the following steps:

[0138] Step 202, according to the delimitation and positioning analysis of the service domain data, the complaint problem corresponding to the VoLTE complaint data is determined.

[0139] Step 203, judging whether the complaint problem belongs to user subscription problem.

[0140] If the result of step 203 is yes, the process ends.

[0141] If the result of step 203 is no, step 204 is entered, and continuous call problem definition positioning analysis is performed according to the operation domain data to determine the complaint problem corresponding to the VoLTE complaint data.

[0142] Step 205, voice quality problem definition positioning analysis is performed according to the operation domain data to determine the complaint problem corresponding to the VoLTE complaint data.

[0143] Step 206, performance index problem definition positioning analysis is performed according to the operation domain data to determine the complaint problem corresponding to the VoLTE complaint data.

[0144] Step 207, the complaint problems determined in steps 204, 205 and 206 are comprehensively determined.

[0145] Step 208, the complaint problem is determined.

[0146] It should be noted that the definition positioning analysis in steps 202, 204 and 205 above includes definition analysis and positioning analysis.

[0147] In an embodiment, the definition analysis includes continuous call problem definition analysis, and the operation domain data includes signaling data, and in step 103, the definition analysis is performed according to the operation domain data to determine the second VoLTE complaint problem corresponding to the VoLTE complaint data, including:

[0148] The first disconnection reason rule base and the signaling data are matched to determine the second VoLTE complaint problem corresponding to the VoLTE complaint data, wherein the first disconnection reason rule base is related to the continuous call problem.

[0149] In this embodiment, the first disconnection refers to that A calls B but does not connect, and the phone between A and B is interrupted, which is a control plane problem.

[0150] The first disconnection reason rule base can be configured in advance according to expert experience.

[0151] The signaling data is matched with each field in the first disconnection reason rule base to determine the second VoLTE complaint problem.

[0152] It should be noted that the first disconnection reason rule base and the signaling data are matched to obtain a definition result, that is, to determine the second VoLTE complaint problem corresponding to the VoLTE complaint data.

[0153] In an implementation form, the signaling data comprises at least one of outgoing call data, incoming call data, and registration data, and the matching of the first disconnection reason rule base and the signaling data to determine the second VoLTE complaint issue corresponding to the VoLTE complaint data comprises:

[0156] matching the key field of at least one of the MO data, the MT data, and the Register data with the first disconnection reason rule base respectively to determine the second VoLTE complaint issue corresponding to the VoLTE complaint data.

[0159] Further, the key field of at least one of the MO data, the MT data, and the Register data is matched with the first disconnection reason rule base to determine the second VoLTE complaint issue corresponding to the VoLTE complaint data.

[0160] It should be noted that the VoLTE complaint issue positioning method in the embodiment does not match the key field of at least one of the MO data, the MT data, and the Register data with each field in the first disconnection reason rule base, and in this case, the second VoLTE complaint issue corresponding to the VoLTE complaint data is determined as other issues.

[0161] Assuming that the MO data, the MT data and the Register data in the signaling data are acquired, and after judging whether the key fields in the MO data, the MT data and the Register data are null values and setting the key fields corresponding to the null values as preset values, the key fields in the MO data, the MT data and the Register data are matched with the first disconnection reason rule library respectively to determine three second VoLTE complaint problems corresponding to the VoLTE complaint data, and each data corresponds to a second VoLTE complaint problem.
