Description

Technical Field

[0001] This application relates to the field of communication technologies, and in particular, to an anomaly determination method, apparatus, server, and storage medium. Background Art

[0002] Currently, it is possible to determine whether a certain terminal is an abnormal terminal through manual troubleshooting. Specifically, if a certain terminal has abnormal power outages multiple times within a period of time, it can be determined that the terminal is an abnormal terminal.

[0003] However, in the case of a large number of terminals, it may not be possible to accurately and effectively determine abnormal terminals through manual troubleshooting. Summary of the Invention

[0004] This application provides an anomaly determination method, apparatus, server, and storage medium, which solves the technical problem that in the case of a large number of terminals, it may not be possible to accurately and effectively determine abnormal terminals through manual troubleshooting.

[0005] In a first aspect, this application provides an anomaly determination method, including: determining network data of a base station to be identified, where the network data of the base station to be identified includes the access success rate of the base station to be identified, the uplink interference parameter of the base station to be identified, and the uplink weak coverage parameter of the base station to be identified. The access success rate of the base station to be identified is used to represent the probability that at least one terminal corresponding to the base station to be identified successfully accesses the base station to be identified. The uplink interference parameter of the base station to be identified is determined based on the signal quality of each terminal in the at least one terminal, and the uplink weak coverage parameter of the base station to be identified is determined based on the signal strength of each terminal; when the access success rate of the base station to be identified is less than a success rate threshold, the uplink interference parameter of the base station to be identified is greater than an interference parameter threshold, and the uplink weak coverage parameter of the base station to be identified is greater than a weak coverage threshold, determining whether the signal strength of the terminal to be identified is less than a signal strength threshold and whether the signal quality of the terminal to be identified is less than a signal quality threshold, where the terminal to be identified is a terminal included in the at least one terminal; when the signal strength of the terminal to be identified is less than the signal strength threshold, and / or the signal quality of the terminal to be identified is less than the signal quality threshold, determining that the terminal to be identified is an abnormal terminal.

[0006] Optionally, the anomaly determination method further includes: when the status information of the target configuration information is in a normal state, determining whether there is an alarm message for the base station to be identified within a preset duration, where the target configuration information is used to indicate that the base station to be identified has a terminal access function; when there is no alarm message for the base station to be identified within the preset duration, determining whether the access success rate of the base station to be identified is less than the success rate threshold.

[0007] In this application, when the status information of the target configuration information is in a normal state, it indicates that the base station to be identified can normally receive access requests sent by terminals. At this time, the server can determine whether there is any alarm information for the base station to be identified within a preset duration. When there is no alarm information for the base station to be identified within the preset duration, it means that the base station to be identified has not sent any alarm information within the preset duration, which can also be understood as that no abnormal situation has occurred for the base station to be identified within the preset duration. That is, the server can determine that the base station to be identified is in a normal state. At this time, the server can determine whether the access success rate of the base station to be identified is less than the success rate threshold, and further determine whether there is any abnormal terminal among at least one terminal corresponding to the base station to be identified. It can accurately and effectively determine the working state of the base station, thereby improving the determination efficiency of abnormal base stations.

[0008] Optionally, the abnormal determination method further includes: when the status information of the mobile management entity (MME) is in an abnormal state and the status information of the access and mobility management function (AMF) is in an abnormal state, determining the number of abnormalities of at least one temporary mobile subscriber identity (TMSI), where one TMSI is the TMSI included in an access request received by the base station to be identified, and the number of abnormalities of one TMSI is used to represent the number of times the access request corresponding to the TMSI fails to access; when the number of abnormalities of the first TMSI is greater than a preset number and the number of abnormalities of the second TMSI is greater than the preset number, determining whether the first distance information is the same as the second distance information, where the first distance information is the distance information corresponding to the first TMSI, the second distance information is the distance information corresponding to the second TMSI, the first distance information is used to represent the distance between the terminal corresponding to the first TMSI and the base station to be identified, the second distance information is used to represent the distance between the terminal corresponding to the second TMSI and the base station to be identified, the first TMSI is one of the at least one TMSI, and the second TMSI is one of the at least one TMSI other than the first TMSI; when the first distance information is the same as the second distance information, determining whether the signal level of the target terminal is within a preset range, where the target terminal is the terminal corresponding to both the first TMSI and the second TMSI; when the signal level of the target terminal is within the preset range, determining that the target terminal is an abnormal terminal.

[0009] In this application, when the status information of the MME is in an abnormal state and the status information of the AMF is also in an abnormal state, it indicates that both the MME and the AMF are abnormal. It can also be understood that there are some access requests with an access status of access failure, specifically, at least one of the above terminals cannot access the terminal to be identified normally. At this time, the server can determine the number of abnormal occurrences of the TMSI included in each of the at least one access request received by the base station to be identified; when the number of abnormal occurrences of the first TMSI is greater than the preset number, it indicates that the number of abnormal occurrences of the first TMSI is relatively large. It can also be understood that the access requests sent by the terminal corresponding to the first TMSI to the base station to be identified have failed to access multiple times. Similarly, the access requests sent by the terminal corresponding to the second TMSI to the base station to be identified have also failed to access multiple times. At this time, the server can determine whether the first distance information is the same as the second distance information, specifically, determine whether the distance between the terminal corresponding to the first TMSI and the base station to be identified is equal to the distance between the terminal corresponding to the second TMSI and the base station to be identified; when the first distance information is the same as the second distance information, it indicates that the terminal corresponding to the first TMSI and the terminal corresponding to the second TMSI are the same terminal (i.e., the target terminal). At this time, the server can determine whether the signal level of the target terminal is within the preset range; when the signal level of the target terminal is within the preset range, it indicates that the signal level of the target terminal is at a normal level. It can also be understood that the server can determine that the base station to be identified is in a normal state. Then, the server can determine that the efficiency of the target terminal using the signal level is extremely low. In this way, the server can accurately and effectively determine that the target terminal is an abnormal terminal.

[0010] Optionally, the abnormal determination method further includes: obtaining a target time and a target TMSI, where the target time is the sending time when the terminal to be identified sends an access request, and the target TMSI is the TMSI included in the access request sent by the terminal to be identified; querying a first correspondence based on the target time interval and the target TMSI to obtain the IMSI of the terminal to be identified, where the first correspondence is used to indicate the time intervals and TMSIs corresponding to one or more IMSIs, the minimum value of the target time interval is less than or equal to the target time, and the maximum value of the target time interval is greater than or equal to the target time; determining the MDN of the terminal to be identified based on the IMSI of the terminal to be identified and a second correspondence, where the second correspondence includes multiple IMSIs and the MDNs corresponding to the multiple IMSIs respectively; sending a target prompt message to the terminal to be identified based on the MDN of the terminal to be identified, where the target prompt message is used to prompt that there is an abnormality in the terminal to be identified.

[0011] In this application, the server can obtain the target time and the target TMSI. The target time is the time when the access request sent by the terminal to be identified is sent, and the target TMSI is the TMSI included in the access request sent by the terminal to be identified. After that, the server can determine the time interval corresponding to the target time (i.e., the target time interval), and query the first corresponding relationship based on the target time interval and the target TMSI to obtain the IMSI corresponding to both the target time interval and the target TMSI (i.e., the IMSI of the terminal to be identified). Then, the server can determine the MDN corresponding to the IMSI of the terminal to be identified from the second corresponding relationship, that is, it can determine the MDN of the terminal to be identified, which can conveniently and quickly determine the MDN of each terminal. Finally, the server can send a target prompt message to the terminal to be identified based on the MDN of the terminal to be identified, which can accurately and effectively prompt that there is an abnormality in the terminal to be identified and improve the efficiency of anomaly reminder.

[0012] In a second aspect, this application provides an anomaly determination device, including: a determination module; the determination module is used to determine the network data of the base station to be identified, and the network data of the base station to be identified includes the access success rate of the base station to be identified, the uplink interference parameter of the base station to be identified, and the uplink weak coverage parameter of the base station to be identified. The access success rate of the base station to be identified is used to represent the probability that at least one terminal corresponding to the base station to be identified successfully accesses the base station to be identified. The uplink interference parameter of the base station to be identified is determined based on the signal quality of each terminal in the at least one terminal, and the uplink weak coverage parameter of the base station to be identified is determined based on the signal strength of each terminal. The determination module is further used to determine whether the signal strength of the terminal to be identified is less than the signal strength threshold and whether the signal quality of the terminal to be identified is less than the signal quality threshold when the access success rate of the base station to be identified is less than the success rate threshold, the uplink interference parameter of the base station to be identified is greater than the interference parameter threshold, and the uplink weak coverage parameter of the base station to be identified is greater than the weak coverage threshold. The terminal to be identified is the terminal included in the at least one terminal. The determination module is further used to determine that the terminal to be identified is an abnormal terminal when the signal strength of the terminal to be identified is less than the signal strength threshold, and / or the signal quality of the terminal to be identified is less than the signal quality threshold.

[0013] Optionally, the determination module is further used to determine whether there is an alarm message for the base station to be identified within a preset duration when the status information of the target configuration information is in a normal state. The target configuration information is used to indicate that the base station to be identified has the terminal access function. The determination module is further used to determine whether the access success rate of the base station to be identified is less than the success rate threshold when there is no alarm message for the base station to be identified within the preset duration.

[0014] Optionally, the determination module is further configured to determine the number of anomalies of at least one TMSI when the status information of the MME is in an abnormal state and the status information of the AMF is in an abnormal state, where one TMSI is the TMSI included in an access request received by the base station to be identified, and the number of anomalies of one TMSI is used to characterize the number of times the access request corresponding to the TMSI fails to access; the determination module is further configured to determine whether the first distance information is the same as the second distance information when the number of anomalies of the first TMSI is greater than a preset number and the number of anomalies of the second TMSI is greater than the preset number, where the first distance information is the distance information corresponding to the first TMSI, the second distance information is the distance information corresponding to the second TMSI, the first distance information is used to characterize the distance between the terminal corresponding to the first TMSI and the base station to be identified, the second distance information is used to characterize the distance between the terminal corresponding to the second TMSI and the base station to be identified, the first TMSI is one of the at least one TMSI, and the second TMSI is one of the at least one TMSI other than the first TMSI; the determination module is further configured to determine whether the signal level of the target terminal is within a preset range when the first distance information is the same as the second distance information, where the target terminal is the terminal corresponding to both the first TMSI and the second TMSI; the determination module is further configured to determine that the target terminal is an abnormal terminal when the signal level of the target terminal is within the preset range.

[0015] Optionally, the anomaly determination device further includes an acquisition module and a transmission module; the acquisition module is configured to acquire a target time and a target TMSI, where the target time is the transmission time when the terminal to be identified sends an access request, and the target TMSI is the TMSI included in the access request sent by the terminal to be identified; the acquisition module is further configured to query a first correspondence based on a target time interval and the target TMSI to acquire the IMSI of the terminal to be identified, where the first correspondence is used to indicate the time intervals and TMSIs corresponding to one or more IMSIs, the minimum value of the target time interval is less than or equal to the target time, and the maximum value of the target time interval is greater than or equal to the target time; the determination module is further configured to determine the MDN of the terminal to be identified based on the IMSI of the terminal to be identified and a second correspondence, where the second correspondence includes multiple IMSIs and the MDNs corresponding to the multiple IMSIs respectively; the transmission module is configured to send a target prompt message to the terminal to be identified based on the MDN of the terminal to be identified, where the target prompt message is used to prompt that there is an anomaly in the terminal to be identified.

[0016] In a third aspect, the present application provides a server, including: a processor and a memory configured to store processor-executable instructions; wherein, the processor is configured to execute the instructions to implement any one of the optional anomaly determination methods in the above first aspect.

At this time, the server can determine whether there is a terminal among at least one terminal corresponding to the base station to be identified whose signal strength is less than the signal strength threshold and whose signal quality is less than the signal quality threshold. When the signal strength of the terminal to be identified is less than the signal strength threshold, and / or the signal quality of the terminal to be identified is less than the signal quality threshold, it indicates that the signal strength of the terminal to be identified is small and / or the signal quality of the terminal to be identified is poor. At this time, the server can determine the terminal to be identified as an abnormal terminal. It can accurately and effectively determine abnormal terminals, improving the effectiveness of anomaly determination. Description of the Drawings

[0026] The anomaly determination method, device, server, and storage medium provided by the embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0027] In the specification of this application and the accompanying drawings, terms such as "first" and "second" are used to distinguish different objects, rather than to describe a specific order of the objects. For example, the first TMSI and the second TMSI are used to distinguish different TMSIs, rather than to describe a specific order of the TMSIs.

[0028] In addition, the terms "including" and "having" and any variations thereof mentioned in the description of this application are intended to cover non-exclusive inclusion. For example, a process, method, system, product, or device that includes a series of steps or units is not limited to the listed steps or units, but optionally further includes other steps or units not listed, or optionally further includes other steps or units inherent to these processes, methods, products, or devices.

[0029] It should be noted that in the embodiments of this application, words such as "exemplary" or "for example" are used to indicate examples, illustrations, or explanations. Any embodiment or design solution described as "exemplary" or "for example" in the embodiments of this application should not be construed as being more preferred or having more advantages than other embodiments or design solutions. Rather, the use of words such as "exemplary" or "for example" is intended to present the relevant concepts in a specific manner.

[0030] As used in this application, "and / or" includes any one of the two methods or the simultaneous use of both methods.

[0031] In the description of the present application, unless otherwise specified, the meaning of "a plurality of" refers to two or more.

[0032] Based on what is described in the background art, in the case where the number of abnormal terminals is relatively large, it may not be possible to accurately and effectively determine the abnormal terminals through manual investigation. Based on this, an embodiment of the present application provides an abnormal determination method, apparatus, server, and storage medium. The server can determine the network data of the base station to be identified, and the network data of the base station to be identified includes the access success rate of the base station to be identified, the uplink interference parameter of the base station to be identified, and the uplink weak coverage parameter of the base station to be identified. In the case where the access success rate of the base station to be identified is less than the success rate threshold, the uplink interference parameter of the base station to be identified is greater than the interference parameter threshold, and the uplink weak coverage parameter of the base station to be identified is greater than the weak coverage threshold, it indicates that the access situation of the base station to be identified is poor (or it can also be understood that there is an abnormality in the network between the base station to be identified and at least one terminal), and the base station to be identified is in a normal state (or non-abnormal state). At this time, the server can determine whether there is a terminal among at least one terminal corresponding to the base station to be identified whose signal strength is less than the signal strength threshold and whose signal quality is less than the signal quality threshold. In the case where the signal strength of the terminal to be identified is less than the signal strength threshold and / or the signal quality of the terminal to be identified is less than the signal quality threshold, it indicates that the signal strength of the terminal to be identified is small and / or the signal quality of the terminal to be identified is poor. At this time, the server can determine the terminal to be identified as an abnormal terminal. It can accurately and effectively determine the abnormal terminals, improving the effectiveness of abnormal determination.

[0033] Exemplarily, the server that executes the abnormal determination method provided by the embodiment of the present application can be an independent physical server, or a server cluster or distributed system composed of multiple physical servers, or a cloud server that provides basic cloud computing services such as cloud services, cloud databases, cloud computing, cloud functions, cloud storage, network services, cloud communications, middleware services, domain name services, security services, network acceleration services (content delivery network, CDN), and big data and artificial intelligence platforms.

[0034] As Figure 1 shown, the abnormal determination method provided by the embodiment of the present application may include S101 - S103.

[0035] S101. The server determines the network data of the base station to be identified.

[0036] Among them, the network data of the base station to be identified includes the access success rate of the base station to be identified, the uplink interference parameter of the base station to be identified, and the uplink weak coverage parameter of the base station to be identified. The access success rate of the base station to be identified is used to represent the probability that at least one terminal corresponding to the base station to be identified successfully accesses the base station to be identified. The uplink interference parameter of the base station to be identified is determined based on the signal quality of each terminal among the at least one terminal. The uplink weak coverage parameter of the base station to be identified is determined based on the signal strength of each terminal.

[0037] In an implementation manner of the embodiment of the present application, the server may determine the total number of times that the at least one terminal accesses the base station to be identified (or the total number of times that the at least one terminal sends an access request to the base station to be identified), and the number of times that the at least one terminal successfully accesses the base station to be identified. Then, the server determines the ratio between the number of times that the at least one terminal successfully accesses the base station to be identified and the total number as the access success rate of the base station to be identified.

[0038] In an optional implementation manner, the signal quality of a terminal may be the signal to interference plus noise ratio (SINR) of the terminal, and the signal strength of a terminal may be the reference signal receiving power (RSRP) of the terminal.

[0039] Optionally, the server may determine the average value of the signal quality of each terminal among the at least one terminal as the uplink interference parameter of the base station to be identified, and determine the average value of the signal strength of each terminal as the uplink weak coverage parameter of the base station to be identified.

[0040] Exemplarily, the uplink interference parameter of the base station to be identified may be the signal to interference plus noise ratio per radio access bearer (SINR / RAB) of the base station to be identified. The uplink weak coverage parameter of the base station to be identified may be the reference signal receiving power per radio access bearer (RSRP / RAB) of the base station to be identified.

[0041] S102. When the access success rate of the base station to be identified is less than the success rate threshold, the uplink interference parameter of the base station to be identified is greater than the interference parameter threshold, and the uplink weak coverage parameter of the base station to be identified is greater than the weak coverage threshold, the server determines whether the signal strength of the terminal to be identified is less than the signal strength threshold and whether the signal quality of the terminal to be identified is less than the signal quality threshold.

[0042] Wherein, the terminal to be identified is the terminal included in the at least one terminal above.

[0043] It should be understood that when the access success rate of the base station to be identified is less than the success rate threshold, it indicates that the access situation of the base station to be identified is poor (or it can also be understood that there is an abnormality in the network between the base station to be identified and the at least one terminal). At this time, the server can determine whether the uplink interference parameter of the base station to be identified is greater than the interference parameter threshold and whether the uplink weak coverage parameter of the base station to be identified is greater than the weak coverage threshold. When the uplink interference parameter of the base station to be identified is greater than the interference parameter threshold and the uplink weak coverage parameter of the base station to be identified is greater than the weak coverage threshold, it indicates that the base station to be identified is in a normal state (or non-abnormal state). At this time, the server can determine whether there is a terminal in the at least one terminal whose signal strength is less than the signal strength threshold and whose signal quality is less than the signal quality threshold.

[0044] Exemplarily, the above success rate threshold can be 80%, the interference parameter threshold can be 70 db (decibels), and the weak coverage threshold can be -100 dbm (decibel milliwatt).

[0045] S103. When the signal strength of the terminal to be identified is less than the signal strength threshold, and / or the signal quality of the terminal to be identified is less than the signal quality threshold, the server determines that the terminal to be identified is an abnormal terminal.

[0046] It should be understood that when the signal strength of the terminal to be identified is less than the signal strength threshold, and / or the signal quality of the terminal to be identified is less than the signal quality threshold, it indicates that the signal strength of the terminal to be identified is small and / or the signal quality of the terminal to be identified is poor. At this time, the server can determine the terminal to be identified as an abnormal terminal. It can accurately and effectively determine the abnormal terminal, improving the effectiveness of abnormal determination.

[0047] It should be noted that the number of the base stations to be identified can be one or more, and the number of the terminals to be identified can be one or more. The embodiments of the present application do not make specific limitations on the number of the base stations to be identified and the number of the terminals to be identified.

[0048] In an alternative implementation, when the signal strength of the terminal to be identified is greater than or equal to the signal strength threshold and the signal quality of the terminal to be identified is greater than or equal to the signal quality threshold, the server can determine that the terminal to be identified is a normal terminal.

[0049] The technical solutions provided in the above embodiments can at least bring the following beneficial effects: As can be seen from S101 - S103, the server can determine the network data of the base station to be identified, and the network data of the base station to be identified includes the access success rate of the base station to be identified, the uplink interference parameter of the base station to be identified, and the uplink weak coverage parameter of the base station to be identified. When the access success rate of the base station to be identified is less than the success rate threshold, the uplink interference parameter of the base station to be identified is greater than the interference parameter threshold, and the uplink weak coverage parameter of the base station to be identified is greater than the weak coverage threshold, it indicates that the access situation of the base station to be identified is poor (or it can also be understood that there is an abnormality in the network between the base station to be identified and at least one terminal), and the base station to be identified is in a normal state (or non-abnormal state). At this time, the server can determine whether there is a terminal among the at least one terminal corresponding to the base station to be identified whose signal strength is less than the signal strength threshold and whose signal quality is less than the signal quality threshold. When the signal strength of the terminal to be identified is less than the signal strength threshold and / or the signal quality of the terminal to be identified is less than the signal quality threshold, it indicates that the signal strength of the terminal to be identified is small and / or the signal quality of the terminal to be identified is poor. At this time, the server can determine the terminal to be identified as an abnormal terminal. It can accurately and effectively determine the abnormal terminal, improving the effectiveness of abnormal determination.

[0050] Combined with Figure 1 , as Figure 2 shown, the abnormal determination method provided in the embodiments of the present application may further include S104 - S105.

[0051] S104. When the status information of the target configuration information is in a normal state, the server determines whether there is an alarm message for the base station to be identified within a preset duration.

[0052] Wherein, the target configuration information is used to indicate that the base station to be identified has the terminal access function.

[0053] It should be understood that the target configuration information is the configuration information of the base station to be identified. The status information of a configuration information (such as the target configuration information) can be in a normal state or an abnormal state.

[0054] It can be understood that when the status information of the target configuration information is in a normal state, it indicates that the base station to be identified can normally receive access requests sent by terminals (specifically, the above-mentioned at least one terminal). At this time, the server can determine whether there is an alarm message for the base station to be identified within a preset duration, which can also be understood as determining whether the base station to be identified sends out an alarm message within the preset duration.

[0055] S105. When there is no alarm message for the base station to be identified within a preset duration, the server determines whether the access success rate of the base station to be identified is less than the success rate threshold.

[0056] It should be understood that when there is no alarm message for the base station to be identified within a preset duration, it indicates that the base station to be identified has not sent out an alarm message within the preset duration, which can also be understood as that the base station to be identified has not had an abnormal situation within the preset duration, that is, the server can determine that the base station to be identified is in a normal state. At this time, the server can determine whether the access success rate of the base station to be identified is less than the success rate threshold, and further determine whether there is an abnormal terminal among the at least one terminal corresponding to the base station to be identified.

[0057] In an alternative implementation, when there is an alarm message for the base station to be identified within a preset duration, it indicates that the base station to be identified has sent out an alarm message within the preset duration, which can also be understood as that the base station to be identified has had an abnormal situation within the preset duration. At this time, the server can determine that the base station to be identified is in an abnormal state (or the server can determine the base station to be identified as an abnormal base station).

[0058] In another alternative implementation, when the status of the above-mentioned target configuration information is in an abnormal state and / or there is an alarm message for the base station to be identified within a preset duration, the server can also determine that the base station to be identified is in an abnormal state.

[0059] In the embodiments of the present application, when the status information of the target configuration information is in a normal state, it indicates that the base station to be identified can normally receive access requests sent by terminals. At this time, the server can determine whether there is an alarm message for the base station to be identified within a preset duration; when there is no alarm message for the base station to be identified within the preset duration, it indicates that the base station to be identified has not sent out an alarm message within the preset duration, which can also be understood as that the base station to be identified has not had an abnormal situation within the preset duration, that is, the server can determine that the base station to be identified is in a normal state. At this time, the server can determine whether the access success rate of the base station to be identified is less than the success rate threshold, and further determine whether there is an abnormal terminal among the at least one terminal corresponding to the base station to be identified. It can accurately and effectively determine the working state of the base station, and further improve the determination efficiency of abnormal base stations.

[0060] Combined with Figure 1 , such asFigure 3 As shown in Figure 3 , the abnormal determination method provided by the embodiment of the present application may further include S106 - S109.

[0061] S106. When the status information of the MME is in an abnormal state and the status information of the AMF is in an abnormal state, the server determines the number of abnormal occurrences of at least one TMSI.

[0062] Wherein, one TMSI is the TMSI included in an access request received by the to - be - identified base station, and the number of abnormal occurrences of one TMSI is used to characterize the number of times that the access request corresponding to the TMSI is an access failure.

[0063] It should be understood that the to - be - identified base station may receive multiple access requests sent by the above - mentioned at least one terminal, and one access request includes one TMSI.

[0064] It should be understood that when the status information of the MME is in an abnormal state and the status information of the AMF is in an abnormal state, it indicates that both the MME and the AMF are abnormal. It can also be understood that there are some access requests with an access state of access failure, specifically, at least the above - mentioned at least one terminal has a situation where it cannot access the to - be - identified terminal normally. At this time, the server can determine the number of abnormal occurrences of the TMSI included in each of the at least one access request received by the to - be - identified base station.

[0065] In an alternative implementation, the server may store a report of abnormal situations, and based on this report of abnormal situations, obtain the number of MME abnormalities, and then determine the status information of the MME.

[0066] Exemplarily, Table 1 below is an example of the report of abnormal situations provided by the embodiment of the present application. Specifically, the report of abnormal situations includes the type of access failure, the root problem, the primary problem, the number of problems, and the percentage of problems.

[0067] Table 1

[0068]

[0069]

[0070]

[0071] It should be noted that in Table 1, the types of access failures include evolved radio bearer establishment failure and user environment establishment failure. A root problem can include one or more first-level problems. The number of occurrences of a problem is the number of times an abnormal situation occurs due to a root problem or a first-level problem. The percentage of a problem is the ratio between the number of times an abnormal situation occurs due to a root problem or a first-level problem and the total number of abnormal situations. The X2API (Experience 2 Application Program Interface) problem is a problem of the second-generation application program interface platform protocol.

[0072] Optionally, the server may store a TMSI exception data table, and based on this TMSI exception data table, determine the number of exceptions for each TMSI in the above at least one TMSI.

[0073] Optionally, the above TMSI exception data table may further include the number of uplink weak coverage exceptions and the number of uplink interference exceptions for each TMSI in the above at least one TMSI.

[0074] Exemplarily, Table 2 below is an example of the TMSI exception data table provided by the embodiments of the present application.

[0075] Table 2

[0076]

[0077] Assume that the first TMSI (the first TMSI is one of the above at least one TMSI) is E58DBF78, then the server determines that the number of exceptions for the first TMSI is 111074.

[0078] S107. When the number of exceptions for the first TMSI is greater than a preset number and the number of exceptions for the second TMSI is greater than the preset number, the server determines whether the first distance information is the same as the second distance information.

[0079] Wherein, the first distance information is the distance information corresponding to the first TMSI, the second distance information is the distance information corresponding to the second TMSI, the first distance information is used to represent the distance between the terminal corresponding to the first TMSI and the base station to be identified, the second distance information is used to represent the distance between the terminal corresponding to the second TMSI and the base station to be identified, the first TMSI is one of the above at least one TMSI, and the second TMSI is the TMSI other than the first TMSI in the above at least one TMSI.

[0080] It should be understood that when the number of anomalies of the first TMSI is greater than a preset number, it indicates that the number of anomalies of the first TMSI is relatively large. It can also be understood that the access requests sent by the terminal corresponding to the first TMSI to the base station to be identified have failed to access multiple times. Similarly, the access requests sent by the terminal corresponding to the second TMSI to the base station to be identified have also failed to access multiple times. At this time, the server can determine whether the first distance information is the same as the second distance information, specifically, to determine whether the distance between the terminal corresponding to the first TMSI and the base station to be identified is equal to the distance between the terminal corresponding to the second TMSI and the base station to be identified.

[0081] Exemplarily, the distance between a terminal corresponding to a TMSI and the base station to be identified can be the timing advance (TA) of the TMSI.

[0082] S108. When the first distance information is the same as the second distance information, the server determines whether the signal level of the target terminal is within a preset range.

[0083] Wherein, the target terminal is the terminal corresponding to both the above-mentioned first TMSI and the second TMSI.

[0084] It should be understood that when the first distance information is the same as the second distance information, it indicates that the terminal corresponding to the first TMSI and the terminal corresponding to the second TMSI are the same terminal (i.e., the target terminal). At this time, the server can determine whether the signal level of the target terminal is within the preset range.

[0085] S109. When the signal level of the target terminal is within the preset range, the server determines that the target terminal is an abnormal terminal.

[0086] It should be understood that the signal level is the signal strength received by the terminal, and this signal strength is provided by the above-mentioned base station to be identified. When the signal level of the target terminal is within the preset range, it indicates that the signal level of the target terminal is at a normal level. It can also be understood that the server can determine that the base station to be identified is in a normal state. Then, the server can determine that the efficiency of the target terminal using the signal level is extremely low. Thus, the server determines that the target terminal is an abnormal terminal.

[0087] In the embodiments of the present application, when the status information of the MME is in an abnormal state and the status information of the AMF is in an abnormal state, it indicates that both the MME and the AMF are abnormal. It can also be understood that there are some access requests with an access status of access failure, specifically, at least one of the above terminals cannot access the terminal to be identified normally. At this time, the server can determine the number of abnormal occurrences of the TMSI included in each of the at least one access request received by the terminal to be identified; when the number of abnormal occurrences of the first TMSI is greater than the preset number, it indicates that the number of abnormal occurrences of the first TMSI is relatively large. It can also be understood that the access requests sent by the terminal corresponding to the first TMSI to the terminal to be identified have failed to access multiple times. Similarly, the access requests sent by the terminal corresponding to the second TMSI to the terminal to be identified have also failed to access multiple times. At this time, the server can determine whether the first distance information is the same as the second distance information, specifically, determine whether the distance between the terminal corresponding to the first TMSI and the terminal to be identified is equal to the distance between the terminal corresponding to the second TMSI and the terminal to be identified; when the first distance information is the same as the second distance information, it indicates that the terminal corresponding to the first TMSI and the terminal corresponding to the second TMSI are the same terminal (i.e., the target terminal). At this time, the server can determine whether the signal level of the target terminal is within the preset range; when the signal level of the target terminal is within the preset range, it indicates that the signal level of the target terminal is at a normal level. It can also be understood that the server can determine that the terminal to be identified is in a normal state. Then, the server can determine that the efficiency of the target terminal using the signal level is extremely low. In this way, the server can accurately and effectively determine that the target terminal is an abnormal terminal.

[0088] Combined with Figure 1 , as Figure 4 shown, the abnormal determination method provided by the embodiments of the present application may further include S110 - S113.

[0089] S110. The server obtains the target time and the target TMSI.

[0090] Wherein, the target time is the sending time when the above terminal to be identified sends an access request, and the target TMSI is the TMSI included in the access request sent by the terminal to be identified.

[0091] S111. The server queries the first correspondence based on the target time interval and the target TMSI to obtain the IMSI of the terminal to be identified.

[0092] Wherein, the first correspondence is used to indicate the time interval and the TMSI corresponding to one or more IMSIs. The minimum value of the target time interval is less than or equal to the above target time, and the maximum value of the target time interval is greater than or equal to the target time.

[0093] It should be understood that after the server obtains the target moment, it can determine the time interval corresponding to the target moment (i.e., the target time interval). After that, the server can obtain the IMSI of the terminal to be identified based on the target time interval, the target TMSI, and the first corresponding relationship.

[0094] It can be understood that after the server obtains the target TMSI and determines the target time interval, it can determine the IMSI corresponding to both the target time interval and the target TMSI from the first corresponding relationship, and determine the IMSI corresponding to both the target time interval and the target TMSI as the IMSI of the terminal to be identified.

[0095] Exemplarily, Table 3 below is an example of the first corresponding relationship provided by an embodiment of the present application.

[0096] Table 3

[0097]

[0098] Assume that the target moment is 10:15, then the server determines the above target time interval as Time Interval 1.

[0099] Also assume that the above target TMSI is F5861EAC, then the server determines the IMSI of the terminal to be identified as 123456789876543.

[0100] S112. The server determines the MDN of the terminal to be identified based on the IMSI of the terminal to be identified and the second corresponding relationship.

[0101] Wherein, the second corresponding relationship includes multiple IMSIs and the MDNs respectively corresponding to the multiple IMSIs.

[0102] Exemplarily, Table 4 below is an example of the second corresponding relationship provided by an embodiment of the present application.

[0103] Table 4

[0104] IMSI MDN 123456423512423 12345678912 123456789876543 98765432123 987654321234567 54321678987

[0105] Combined with the example in S111 above, the server determines the MDN of the terminal to be identified as 98765432123.

[0106] S113. The server sends a target prompt message to the terminal to be identified based on the MDN of the terminal to be identified.

[0107] Wherein, the target prompt message is used to prompt that there is an abnormality in the terminal to be identified.

[0108] In an embodiment of the present application, the server may obtain a target time and a target TMSI. The target time is the time when the access request sent by the terminal to be identified arrives, and the target TMSI is the TMSI included in the access request sent by the terminal to be identified. After that, the server may determine a time interval corresponding to the target time (i.e., the target time interval), and query a first corresponding relationship based on the target time interval and the target TMSI to obtain an IMSI corresponding to both the target time interval and the target TMSI (i.e., the IMSI of the terminal to be identified). Then, the server may determine an MDN corresponding to the IMSI of the terminal to be identified from a second corresponding relationship, that is, the MDN of the terminal to be identified can be determined, which can conveniently and quickly determine the MDN of each terminal. Finally, the server may send a target prompt message to the terminal to be identified based on the MDN of the terminal to be identified, which can accurately and effectively prompt that there is an abnormality in the terminal to be identified and improve the efficiency of abnormality reminder.
