[0026] To enable those skilled in the art to better understand the technical solutions of the present disclosure, the problem definition method, device, and computer-readable medium provided by the embodiments of the present disclosure will be described in detail below with reference to the accompanying drawings.

[0027] The present disclosure will be described more fully hereinafter with reference to the accompanying drawings. However, the illustrated embodiments may be embodied in different forms, and the present disclosure should not be construed as limited to the embodiments set forth below. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.

[0028] The accompanying drawings of the embodiments of the present disclosure are used to provide a further understanding of the embodiments of the present disclosure, and constitute a part of the specification. Together with the detailed embodiments, they are used to explain the present disclosure and do not constitute a limitation to the present disclosure. By describing the detailed embodiments with reference to the accompanying drawings, the above and other features and advantages will become more apparent to those skilled in the art.

[0029] The present disclosure may be described with reference to plan views and / or cross-sectional views by means of ideal schematic diagrams of the present disclosure. Therefore, the example illustrations may be modified according to manufacturing techniques and / or tolerances.

[0030] In the case of no conflict, the embodiments of the present disclosure and the features in the embodiments may be combined with each other.

[0031] The terms used in the present disclosure are only for describing specific embodiments and are not intended to limit the present disclosure. As used in the present disclosure, the term "and / or" includes any and all combinations of one or more of the associated listed items. As used in the present disclosure, the singular forms "a" and "the" are also intended to include the plural forms unless the context clearly indicates otherwise. As used in the present disclosure, the terms "comprising", "made of", specify the presence of the stated features, wholes, steps, operations, elements and / or components, but do not preclude the presence or addition of one or more other features, wholes, steps, operations, elements, components and / or their groups.

[0032] Unless otherwise defined, all terms (including technical and scientific terms) used in the present disclosure have the same meaning as commonly understood by those of ordinary skill in the art. It will also be understood that terms such as those defined in common dictionaries should be interpreted as having a meaning consistent with their meaning in the context of the relevant art and the present disclosure, and will not be interpreted as having an idealized or overly formal meaning unless the present disclosure clearly so defines.

[0033] The present disclosure is not limited to the embodiments shown in the drawings, but includes modifications to the configurations formed based on the manufacturing process. Therefore, the regions illustrated in the drawings have schematic attributes, and the shapes of the regions shown in the figures illustrate the specific shapes of the regions of the elements, but are not intended to be restrictive.

[0034] In the process of handling complaints about poor user Internet access experience, operators usually focus on wireless network problems. However, problems such as packet loss and congestion in the bearer network can also lead to poor user Internet access experience, but the complaint handling team lacks means to delimit and locate the complaint problems, that is, lacks means to determine whether the problem causing the poor perception may be a bearer side problem and to locate the bearer side problem.

[0035] In order to solve at least one problem existing in the related art, on the first hand, embodiments of the present disclosure provide a problem delimitation method. This delimitation method can be used to delimit a problem, that is, to determine whether the problem is a bearer side problem.

[0036] As Figure 1 shown, the problem delimitation method provided by the embodiments of the present disclosure includes the steps:

[0037] S101: Determine the resident cell where the problem occurs and the resident base station where the resident cell is located;

[0038] S102: Obtain the key quality indicators (KQIs) of multiple cells in the resident base station, where the multiple cells include the resident cell; and

[0039] S103: When the number of cells whose KQIs meet the first standard among the multiple cells is greater than or equal to the first threshold, at least obtain the key performance indicators (KPIs) of the resident base station, and judge whether the problem is a bearer side problem based on the obtained KPIs.

[0040] In some embodiments, as Figure 2 shown, the problem delimitation method provided by the embodiments of the present disclosure may include the steps:

[0041] S101: Determine the resident cell where the problem occurs and the resident base station where the resident cell is located;

[0042] S102: Obtain the key quality indicators (KQIs) of multiple cells in the resident base station, where the multiple cells include the resident cell;

[0043] S103’: When the number of cells whose KQIs meet the first standard among the multiple cells is greater than or equal to the first threshold, at least obtain the key performance indicators (KPIs) of the resident base station, and judge whether the problem is a radio side problem or a bearer side problem based on the obtained KPIs; and

[0044] S104: When the number of cells whose KQIs meet the first standard among the multiple cells is less than the first threshold, determine that the problem is a radio side problem (that is, the problem occurs on the radio side).

[0045] In step S101, when the problem is a customer complaint problem, the information of the resident cell where the complaint occurs and the resident base station where the resident cell is located can be obtained based on the user number. When the problem is a problem actively monitored by the operator, the information of the corresponding resident cell and resident base station is associated at the time of problem discovery. The information of the resident cell and resident base station obtained through the user number and the problem actively monitored by the operator and the confirmation of the information of the resident cell and resident base station can all adopt existing solutions. For example, the information of the resident cell and resident base station where the user is located (i.e., where the problem is located) can be obtained through a data acquisition system and a radio network management system. Another example is that problems (abnormalities) can be actively discovered by analyzing the information collected by the data acquisition system, and the information of the resident cell and resident base station corresponding to the problem can be obtained.

[0046] In step S102, the KQIs of all cells in the resident base station can be obtained. Of course, according to the actual situation, the KQIs of some cells in the resident base station can also be selectively obtained. The KQI information can be obtained through conventional methods, such as through probe collection, data middle platform, radio network management, etc. In some embodiments, it is obtained through the user KQI data collection module in the data acquisition system. The user KQI data collection module can obtain the KQI of the cell based on the probe device deployed in the core network and / or the radio network management system.

[0047] In addition, the KQI includes indicators related to multiple services. The KQI obtained in the embodiments of the present disclosure may involve one or more of the following services: web page, game, video, voice call, and video live broadcast. For example, it may include common KQIs such as the average web page opening delay of users under the cell, video download rate, and game delay. Correspondingly, the first criterion includes: the conditions of all indicators included in the KQI (i.e., including the threshold values for all indicators included in the KQI). In some embodiments, the obtained KQI information includes mandatory fields such as time, site id, cell id, user number, etc. The KQI can select indicators with high attention according to the network situation (for example, at least including video rate and web page opening delay), as Figure 3 shown. For the obtained such as Figure 3The KPI information shown, the first criterion includes at least conditions for video rate and web page opening delay (or threshold values for video rate and web page opening delay, which can be flexibly selected according to actual applications. In some embodiments, the first criterion is: video rate < 256K / s; web page opening delay > 70ms. In the present disclosure, satisfying any one of the conditions in the first criterion is regarded as satisfying the first criterion. When the KQI of a cell satisfies the first criterion, it is determined that the KQI of the cell is of poor quality; in other words, a cell with poor KQI quality is a cell whose KQI satisfies the first criterion. Of course, the present disclosure embodiments do not limit the selection of specific indicators included in the KQI, and can be specifically selected according to actual applications and needs; correspondingly, the first criterion can also be adjusted according to actual applications and needs. In addition, the KQI of a cell can be the average value of the KQIs of all users in the cell, or other values obtained based on the KQIs of all users in the cell.

[0048] The KPI in step S103 / S103’ includes indicators of multiple dimensions. In the embodiments of the present disclosure, the KPI of the base station obtained can at least include indicators characterizing the capacity and performance of the bearer network. In some embodiments, the KPI obtained at least includes the delay and packet loss rate between devices. In addition, the KPI of the base station can be obtained through the bearer-side KPI acquisition module in the data acquisition system. The bearer-side KPI acquisition module can obtain the KPI of the base station based on the bearer network management system.

[0049] In addition, the first threshold n (n is an integer) is the minimum number of cells for determining whether there is a bearer link problem in a certain base station. According to experience, n can be set to satisfy the condition: 6 ≤ n ≤ 15. Of course, the value of the first threshold n can also be adjusted according to the actual situation on site.

[0050] Through the problem definition method provided by the embodiments of the present disclosure, problems (including problems complained by customers and problems actively discovered by operators) can be quickly defined based on KQI and KPI, and it can be determined whether the problem is a bearer-side problem (for example, a radio-side problem or a bearer-side problem), so as to guide the operation and maintenance personnel to accurately handle the problem. It can improve the processing efficiency and service quality.

[0051] The problem definition method provided by the embodiments of the present disclosure can be applied to various cellular networks such as UMTS (Universal Mobile Telecommunications System), LTE (Long Term Evolution), and 5G (fifth-generation). Figure 4 Shows a networking schematic diagram of a cellular network. As Figure 4As shown, a cellular network generally may include a core network 1, a bearer network 2, and a radio network 3. The core network 1 includes gateway devices such as an SGW (Serving GateWay) and a PGW (Packet Data Network GateWay). The radio network 3 includes radio base stations, such as an EnodeB (Evolved Node B) and a GnodeB (the next Generation Node B). The bearer network 2 generally adopts a three-layer networking structure, that is, it includes an access layer, an aggregation layer, and a core layer. The access layer is provided with UPE (User-end Provider Edge; user-side PE) and switch (ACC) devices; the aggregation layer is provided with SPE (Service Provider-end PE; operator-side PE) devices; the core layer is provided with NPE (Network Provider-end PE; network-side PE) devices. Specifically, the UPE directly connects to users and mainly completes the user access function. The SPE accesses the UPE and is located inside the network, mainly completing the management and distribution of VPN routes. The NPE connects to the SPE and faces the network side. In Figure 4 In the networking structure shown, the radio base stations EnodeB or GnodeB in the radio network 3 are usually co-deployed with the ACC access nodes, and devices such as the SGW and PGW in the core network are usually co-deployed with the NPE devices. It can be understood that Figure 4 is only a common exemplary networking structure of a cellular network, and the actual networking structure of the cellular network may have different structures. For the convenience of understanding the technical solutions of the present disclosure, the following will refer to Figure 4 the structure of the bearer network 2 shown for description.

[0052] In some embodiments, when the number of cells in which the KQI meets the first standard in multiple cells is greater than or equal to the first threshold, at least obtaining the KPI of the resident base station and determining whether the problem is a bearer-side problem based on the obtained KPI (step S103) may include:

[0053] S1031: Obtain the KPI of the resident base station;

[0054] S1033: When the KPI of the resident base station meets the second standard, obtain the KPIs of multiple other base stations in the access ring where the resident base station is located; and

[0055] S1035: When the KPIs of each base station between the resident base station and the UPE connected to the access ring all meet the second standard, determine that the problem is a bearer-side problem.

[0056] In some embodiments, as Figure 5As shown, when the number of cells with KQI meeting the first criterion in multiple cells is greater than or equal to the first threshold, at least obtaining the KPI of the resident base station and determining whether the problem is a radio side problem or a bearer side problem based on the obtained KPI (step S103') may include:

[0057] S1031: Obtain the KPI of the resident base station;

[0058] S1032: When the KPI of the resident base station does not meet the second criterion, determine that the problem is a radio side problem;

[0059] S1033: When the KPI of the resident base station meets the second criterion, obtain the KPIs of multiple other base stations in the access ring where the resident base station is located;

[0060] S1034: When the KPI of at least one base station between the resident base station and the UPE connected to the access ring does not meet the second criterion, determine that the problem is a radio side problem; and

[0061] S1035: When the KPIs of each base station between the resident base station and the UPE connected to the access ring all meet the second criterion, determine that the problem is a bearer side problem.

[0062] In step S1031, the bearer side can mainly obtain two KPIs, namely the delay and packet loss rate between devices. For example, relevant KPIs can be obtained by configuring measurement tasks of the TWAMP (Two-Way Active Measurement Protocol) standard protocol.

[0063] The second criterion includes: conditions for all indicators included in the KPI (i.e., including the threshold values for all indicators included in the KPI). When the obtained KPI includes at least the delay and packet loss rate between devices, the second criterion includes at least conditions for the delay and packet loss rate (i.e., the threshold values for the delay and packet loss rate). In some embodiments, the second criterion is: packet loss rate > 5%, delay > 60 ms. In the present disclosure, satisfying any one of the conditions in the second criterion is regarded as satisfying the second criterion. When the obtained KPI meets the second criterion, it is determined that the KPI is of poor quality; in other words, the KPI being of poor quality means that the KPI meets the second criterion. In step S1032, if it is found that the KPI of the resident site is not of poor quality, it can be determined that the problem is a radio side problem.

[0064] In step S1033, if it is found that the KPI of the resident site is of poor quality, continue to obtain the KPIs of multiple other base stations in the access ring where the resident base station is located. As Figure 6As shown, each access ring in the access layer of the bearer network accesses multiple (e.g., 5 - 8) base stations. When the KPI of the resident site is of poor quality, continue to obtain the KPIs of other base stations within the access ring to which the resident base station belongs (i.e., the access ring to which the resident base station is connected).

[0065] In step S1034, if the KPI of at least one base station between the resident base station and the UPE connected to the access ring does not meet the second criterion (i.e., not every base station between the resident base station and the UPE connected to the access ring has poor - quality KPI), it is determined that the problem is a radio - side problem.

[0066] In step S1035, if the KPI of every base station between the resident base station and the UPE connected to the access ring meets the second criterion (i.e., the KPI of every base station between the resident base station and the UPE connected to the access ring is of poor quality), it is determined that the problem is a bearer - side problem (i.e., the problem lies on the bearer side). For example, as Figure 6 shown, the KPIs of the two base stations between the left - hand UPE and the resident base station in the figure are both of poor quality. At this time, it can be determined that the problem is a bearer - side problem.

[0067] For radio - side problems, the problem can be analyzed based on existing radio - side problem analysis methods to further determine the cause of the problem (such as coverage, interference, capacity, etc.). For example, the cell coverage situation (weak coverage, overlapping coverage, or over - coverage) can be judged by RSRP (Reference Signal Receiving Power) or grid RSRP; the uplink interference and modulo - three (mod 3) interference can be judged based on the user uplink SINR (Signal to Interference plus Noise Ratio); whether there is congestion can be judged based on the utilization rate of the cell or base - station PRB (Physical Resource Block).

[0068] For bearer - side problems, as Figure 7 shown, the problem - definition method provided by the embodiments of the present disclosure further includes step S1036: locating the problem network segment of the bearer network.

[0069] In some embodiments, the KPI is obtained by configuring a TWAMP standard - protocol measurement task, and as Figure 8As shown, the KPIs of the base station can be obtained through three measurements (Measurement 1, Measurement 2, and Measurement 3). Among them, in the first measurement (Measurement 1), the base station is the source network element, and the xGW (such as SGW, PGW, etc.) in the core network or the NPE in the bearer network is the destination network element; in the second measurement (Measurement 2), the base station is the source network element, and the SPE in the bearer network is the destination network element; in the third measurement (Measurement 3), the base station is the source network element, and the UPE in the bearer network is the destination network element. An example of the KPI information obtained through the three measurements is as Figure 9 shown. In the following, for ease of explanation, the KPI obtained by Measurement 1 is called the first KPI, the KPI obtained by Measurement 2 is called the second KPI, and the KPI obtained by Measurement 3 is called the third KPI. Correspondingly, Figure 9 in it, the Measurement 1 delay and the Measurement 1 packet loss rate are the first KPI, the Measurement 2 delay and the Measurement 2 packet loss rate are the second KPI, and the Measurement 3 delay and the Measurement 3 packet loss rate are the third KPI.

[0070] It should be noted that only the first KPI can be used in the process of determining whether the problem is on the radio side or the bearer side. That is to say, each of the KPIs of the resident base station obtained in step S1031 and the KPIs of other multiple base stations in the access ring where the resident base station is located obtained in step S1033 can only include the first KPI obtained through Measurement 1. At this time, as Figure 10 shown, locating the problem network segment of the bearer network (step S1036) can include:

[0071] S01: Obtain the second KPI and the third KPI of the resident base station; and

[0072] S02: Locate the problem network segment based on the second KPI and the third KPI of the resident base station.

[0073] Of course, each of the KPIs of the resident base station obtained in step S1031 and the KPIs of other multiple base stations in the access ring where the resident base station is located obtained in step S1033 can also include Figure 9 the KPIs obtained through the three measurements shown, that is, it can include the first KPI, the second KPI, and the third KPI. At this time, since the second KPI and the third KPI of the resident base station have been obtained, locating the problem network segment of the bearer network (step S1036) can include:

[0074] S02: Locate the problem network segment based on the second KPI and the third KPI of the resident base station.

[0075] In some embodiments, as Figure 11 shown, locating the problem network segment based on the second KPI and the third KPI of the resident base station (step S02) can include:

[0076] S021: When the second KPI does not meet the second standard, determine that the problematic network segment is the link between the SPE and the NPE;

[0077] S022: When the second KPI meets the second standard and the third KPI does not meet the second standard, determine that the problematic network segment is the link between the UPE and the SPE; and

[0078] S023: When both the second KPI and the third KPI meet the second standard, determine that the problematic network segment is the link between the resident base station and the UPE.

[0079] The problem definition method provided by the embodiments of the present disclosure can not only determine whether the problem is a bearer - side problem (for example, whether it is a network - side problem or a bearer network - side problem), but also specifically locate the problem on the bearer network side. For the problems complained by customers, through the problem definition method provided by the embodiments of the present disclosure, the operator's complaint handling team can quickly define and locate the problem, and guide the operation and maintenance personnel to perform precise processing, improving the processing efficiency; for the problems actively discovered by the operator, it can also arrange the operation and maintenance personnel to perform precise processing in a timely manner, improving the service quality.

[0080] The problem definition method provided by the embodiments of the present disclosure can be implemented through a problem analysis module. The data analysis module can be an independent big data server cluster, which is used to receive various data and perform operations such as data storage, cleaning, and analysis. The data analysis module can obtain the information of the resident cell where the problem is located and the resident base station where the resident cell is located through existing data acquisition systems and devices (such as radio network management); analyze the average KQI information of the resident cell and other cells under the same base station (resident base station); analyze the KPI information of the resident base station and other base stations in the same access ring; and when determining that the problem is a bearer - side problem, determine the specific poor - quality network segment of the bearer link through the results of three measurements. Of course, the data analysis module can also be an independent server that can implement the above functions.
