Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments.

[0027] According to an embodiment of the present invention, an embodiment of a method for evaluating base station handover quality is provided. It should be noted that the steps shown in the flowchart of the accompanying drawings can be executed in a computer system such as a set of computer executable instructions, and although a logical order is shown in the flowchart, in some cases, the steps shown or described can be executed in an order different from that shown here.

[0028] Figure 1 is a flow chart of a method for evaluating base station handover quality according to an embodiment of the present invention. Figure 1 As shown, the method comprises the following steps:

[0029] Step S102, in the case of handover from the first base station to the second base station, obtaining first cell communication data corresponding to the first base station and second cell communication data corresponding to the second base station from multiple preset cell communication data recorded in the big data lake, and using the first cell communication data and the second cell communication data as target cell communication data;

[0030] Step S104, according to the duration of handover from the first base station to the second base station, determining a target evaluation index corresponding to the duration from a plurality of preset evaluation indexes for evaluating base station handover quality;

[0031] Step S106, obtaining the data to be evaluated from the target cell communication data according to the target evaluation index;

[0032] Step S108, when the data to be evaluated meets the abnormal threshold condition corresponding to the target evaluation index, the communication cell corresponding to the second base station is determined to be an abnormal cell, and the base station handover quality from the first base station to the second base station is determined to be unqualified.

[0033] In an embodiment of the present invention, in the case of handover from a first base station to a second base station, first cell communication data corresponding to the first base station and second cell communication data corresponding to the second base station are obtained from multiple preset cell communication data recorded in the big data lake, and the first cell communication data and the second cell communication data are used as target cell communication data; according to the duration after handover from the first base station to the second base station, a target evaluation indicator corresponding to the duration is determined from multiple preset evaluation indicators for evaluating the base station handover quality; according to the target evaluation indicator, the data to be evaluated is obtained from the target cell communication data; when the data to be evaluated meets the abnormal threshold condition corresponding to the target evaluation indicator, the communication cell corresponding to the second base station is determined to be an abnormal cell, and the base station handover quality from the first base station to the second base station is determined to be unqualified, thereby achieving the purpose of selecting different target evaluation indicators according to different durations to evaluate the base station handover quality, thereby achieving the technical effect of actively monitoring the base station handover quality, and further solving the technical problem that the prior art cannot actively monitor the base station handover quality.

[0034] It should be noted that base stations are key facilities in mobile communication networks, used to transmit and receive wireless signals. They are usually located in specific locations, such as tower tops or buildings, to provide wide signal coverage. A base station contains multiple communication cells, each of which covers a certain geographical area.

[0035] It should be noted that a communication cell, also called a cellular cell, refers to an area covered by a base station or a part of a base station (such as a sector antenna). In this area, a mobile device can communicate with the base station through a wireless channel.

[0036] In the above step S102, the first base station includes a first communication cell, and the mobile device can communicate with the first base station through a wireless channel in the first communication cell, wherein the first cell communication data represents the communication status of the first communication cell.

[0037] In the above step S102, the second base station includes a second communication cell, and the mobile device can communicate with the second base station through a wireless channel in the second communication cell, wherein the second cell communication data represents the communication status of the second communication cell.

[0038] In the above step S102, the target cell communication data includes the first cell communication data and the second cell communication data. The difference between the first base station and the second base station in the wireless communication environment can be determined based on the first cell communication data and the second cell communication data.

[0039] It should be noted that cutover, also known as network migration, refers to physical or logical changes to the network lines or devices in use. Among them, base station cutover refers to physical or logical changes to the network lines or base station devices in use to improve network performance, perform equipment updates, etc. In this application, cutover from a first base station to a second base station means: migrating a mobile device that wirelessly communicates with the first base station to the second base station.

[0040] As an optional example, the big data lake can manage the communication data of multiple base stations and the configuration data of each base station. Therefore, when it is necessary to obtain the cell communication data of the first base station and the second base station, it can be retrieved from the big data lake.

[0041] Figure 2 is a schematic diagram of a data push process according to an embodiment of the present invention, such as Figure 2 As shown in the figure, the wireless OMC-R is a management platform for unified management of wireless access network elements. It mainly has management and northbound network management interfaces such as configuration management, fault, performance, topology, software, security, test tracking, system, and command line operation. The configuration data, performance data, and alarm data of the wireless OMC-R are collected by the acquisition and control platform and pushed to the data and resource sharing platform. The data and resource sharing platform further pushes the data to the wireless network capability scheduling subsystem, supplements the manually reported base station information, and distributes it to the data and resource sharing platform again. Then, after the big data lake obtains the data from the data and resource sharing platform, the engineer retrieves it through the capability opening platform.

[0042] In the above step S104, the duration after handover from the first base station to the second base station refers to the length of time that the second base station provides communication services for the mobile devices originally connected to the first base station after the first base station is handed over to the second base station.

[0043] In the above step S104, after the base station cutover, the corresponding target evaluation index can be selected for evaluation according to the duration. For example, within a short period of time (such as an instantaneous time) after the base station cutover, it can be determined whether the cutover base station (such as the second base station) can provide communication services for the mobile devices originally connected to the first base station; after a period of time after the base station cutover is completed, the impact of the base station cutover on the connected mobile devices can be determined.

[0044] In the above step S104, different durations correspond to different target evaluation indicators, and each duration may correspond to one or more target evaluation indicators.

[0045] In the above step S106, different target evaluation indicators use different data to be evaluated. Therefore, after the target evaluation indicator is determined, the data to be evaluated required for each target evaluation indicator can be extracted from the target cell communication data.

[0046] In the above step S108, if the target evaluation indicators are different, then the standards for evaluating the data to be evaluated using the target evaluation indicators are also different. Therefore, different target evaluation indicators may have different abnormal threshold conditions. Further, when evaluating the quality of base station handover, the abnormal threshold condition corresponding to each target evaluation indicator may be determined first, and then the data to be evaluated corresponding to the target evaluation indicator may be compared with the abnormal threshold condition corresponding to the same target evaluation indicator, and then the base station handover quality may be evaluated based on the comparison result.

[0047] It should be noted that, when the data to be evaluated meets the abnormal threshold conditions corresponding to the target evaluation indicators, it means that after handover from the first base station to the second base station, the second base station cannot provide good communication services, which means that the base station handover quality from the first base station to the second base station is unqualified.

[0048] As an optional embodiment, when the data to be evaluated meets the abnormal threshold condition corresponding to the target evaluation indicator, determining that the communication cell corresponding to the second base station is an abnormal cell includes: evaluating the base station handover quality based on multiple durations, and obtaining pre-evaluation results corresponding to multiple durations, wherein each pre-evaluation result is used to indicate whether the communication cell corresponding to the second base station is an abnormal cell within the corresponding duration, and when there are multiple target evaluation indicators corresponding to the duration, and the data to be evaluated meets the abnormal threshold condition corresponding to any one of the target evaluation indicators, determining that the pre-evaluation result indicates that the communication cell corresponding to the second base station is determined to be an abnormal cell; when at least one pre-evaluation result among the pre-evaluation results corresponding to multiple durations indicates that the communication cell corresponding to the second base station is an abnormal cell, determining that the communication cell corresponding to the second base station is an abnormal cell.

[0049] In the above-mentioned embodiment of the present application, after handover from the first base station to the second base station, the base station handover quality can be evaluated based on multiple durations respectively, and pre-evaluation results corresponding to the multiple durations can be obtained. Then, by combining the multiple pre-evaluation results, a more accurate evaluation of the base station handover quality can be performed.

[0050] Optionally, the target evaluation indicator corresponding to each duration may be one or more. When there is only one target evaluation indicator, if the base station handover quality indicated by the pre-evaluation result of the target evaluation indicator is unqualified, then the base station handover quality corresponding to the duration is determined to be unqualified; when there are multiple target evaluation indicators, as long as the evaluation result based on any one of the target evaluation indicators indicates that the base station handover quality is unqualified, then the base station handover quality corresponding to the duration is determined to be unqualified; that is, when there are multiple target evaluation indicators, if the evaluation result based on any one of the target evaluation indicators indicates that the base station handover quality is qualified, then the base station handover quality corresponding to the duration is determined to be qualified.

[0051] Optionally, among multiple pre-evaluation results obtained based on multiple durations, as long as any pre-evaluation result indicates that the base station handover quality is unqualified, the final evaluation result is determined to be that the base station handover quality is unqualified, that is, the communication cell corresponding to the second base station is an abnormal cell.

[0052] As an optional embodiment, multiple preset evaluation indicators include at least: a handover duration indicator, according to the duration after handover from the first base station to the second base station, determining the target evaluation indicator corresponding to the duration from multiple preset evaluation indicators for evaluating the base station handover quality includes: when the duration is not greater than the first duration threshold, determining the target evaluation indicator as the handover duration indicator.

[0053] Optionally, the first duration threshold may be one day. When the duration is not greater than the first duration threshold, it may represent the time after the cutover is not completed.

[0054] In the above embodiment of the present application, after handover from a first base station to a second base station, in order to evaluate whether the second base station is available, it can be determined based on the handover duration indicator whether the time it takes for the second base station to respond to communication with the mobile device after the handover is completed is too long. Furthermore, when the duration after handover from the first base station to the second base station is less than the first duration threshold, the handover duration indicator can be used as the target evaluation indicator corresponding to the current duration.

[0055] Optionally, the first duration threshold may be 1 day.

[0056] As an optional embodiment, the communication data of the first cell includes at least: the first time when the communication cell corresponding to the first base station reported data for the last time, and the communication data of the second cell includes at least: the second time when the communication cell corresponding to the second base station reported data for the first time after the cutover. When the cutover duration is not greater than the first duration threshold, after determining that the target evaluation indicator is the cutover duration indicator, the method also includes: according to the cutover duration indicator, obtaining the first time from the communication data of the first cell, and obtaining the second time from the communication data of the second cell; determining the time interval between the first time and the second time as the cutover duration, wherein the data to be evaluated includes at least: the cutover duration; judging whether the cutover duration is not less than a preset duration threshold, wherein the preset duration threshold is the abnormal threshold condition corresponding to the cutover duration indicator; when the cutover duration is not less than the preset duration threshold, determining that the communication cell corresponding to the second base station is an abnormal cell.

[0057] In the above embodiment of the present application, the communication data of the first cell at least includes: the first time when the communication cell corresponding to the first base station reports data for the last time, and the communication data of the second cell at least includes: the second time when the communication cell corresponding to the second base station reports data for the first time after the handover, and the time interval between the first time and the second time is the handover duration from the first base station to the second base station, and then the handover duration is compared with the preset duration threshold. If the handover duration is not less than the preset duration threshold, it means that the interval event of the base station responding to the mobile device after the handover is too long, then the communication cell corresponding to the second base station is regarded as an abnormal cell, and the base station handover quality is determined to be unqualified.

[0058] As an optional embodiment, multiple preset evaluation indicators include at least: a data flow indicator, a voice traffic volume indicator, a voice call drop rate indicator, a user context call drop rate indicator, a voice connection rate indicator, a physical resource block average utilization rate indicator, an uplink perception rate indicator, a downlink perception rate indicator, a coverage distance indicator, a number of complaints indicator, a cell noise floor indicator, a standing wave ratio alarm indicator, a reference signal power indicator and a minimum access level indicator. According to the duration after handover from the first base station to the second base station, determining the target evaluation indicator corresponding to the duration from multiple preset evaluation indicators for evaluating the base station handover quality includes: when the duration meets the second duration threshold, determining the target evaluation indicator includes at least one of the following: a data flow indicator, a voice traffic volume indicator, a voice call drop rate indicator, a user context call drop rate indicator, a voice connection rate indicator, a physical resource block average utilization rate indicator, an uplink perception rate indicator, a downlink perception rate indicator, a coverage distance indicator, a number of complaints indicator, a cell noise floor indicator, a standing wave ratio alarm indicator, a reference signal power indicator and a minimum access level indicator.

[0059] In the above embodiments of the present application, different durations may correspond to different target evaluation indicators, and there may be multiple target evaluation indicators corresponding to the duration. Then, when the duration meets the second duration threshold, at least one of the data flow indicator, voice traffic volume indicator, voice call drop rate indicator, user context call drop rate indicator, voice connection rate indicator, physical resource block average utilization indicator, uplink perception rate indicator, downlink perception rate indicator, coverage distance indicator, number of complaints indicator, cell noise floor indicator, standing wave ratio alarm indicator, reference signal power indicator and minimum access level indicator may be used as the target evaluation indicator. Then, based on multiple target evaluation indicators, the base station handover quality can be evaluated more accurately.

[0060] Optionally, the second duration threshold may be 1 day.

[0061] As an optional embodiment, the method also includes: according to the second duration threshold, taking the handover time when the first base station is handed over to the second base station as the end point, intercepting the first data to be evaluated of the first base station before the handover from the communication data of the first cell, wherein the time span of the first data to be evaluated is the same as the time span of the second duration threshold; according to the second duration threshold, taking the handover time when the first base station is handed over to the second base station as the starting point, intercepting the second data to be evaluated of the second base station after the handover from the communication data of the second cell, wherein the time span of the second data to be evaluated is the same as the time span of the second duration threshold; judging whether the difference between the first data to be evaluated and the second data to be evaluated meets the first abnormal difference condition, wherein the first abnormal difference condition is the abnormal threshold condition corresponding to the target evaluation indicator; when the difference between the first data to be evaluated and the second data to be evaluated meets the first abnormal difference condition, determining that the communication cell corresponding to the second base station is an abnormal cell.

[0062] In the above embodiment of the present application, according to the time span of the second duration threshold, data to be evaluated with the same time span can be intercepted from the first base station before the cutover and the second base station after the cutover for comparison, and the difference between the first data to be evaluated of the first base station and the second data to be evaluated of the second base station under the same time span is determined, and then the difference is compared with the corresponding first abnormal difference condition to determine whether the difference meets the first abnormal difference condition, and the base station cutover quality is further evaluated according to the judgment result.

[0063] As an optional embodiment, the method also includes: when the duration meets the third duration threshold, according to the third duration threshold, with the handover time when the first base station is handed over to the second base station as the end point, intercepting the third data to be evaluated of the first base station before the handover from the first cell communication data, wherein the third duration threshold is greater than the second duration threshold, and the time span of the third data to be evaluated is the same as the time span of the third duration threshold; according to the third duration threshold, with the handover time when the first base station is handed over to the second base station as the starting point, intercepting the fourth data to be evaluated of the second base station after the handover from the second cell communication data, wherein the time span of the fourth data to be evaluated is the same as the time span of the third duration threshold; judging whether the difference between the third data to be evaluated and the fourth data to be evaluated meets the second abnormal difference condition, wherein the second abnormal difference condition is the abnormal threshold condition corresponding to the target evaluation indicator; when the difference between the third data to be evaluated and the fourth data to be evaluated meets the second abnormal difference condition, determining that the communication cell corresponding to the second base station is an abnormal cell.

[0064] In the above-mentioned embodiment of the present application, according to the time span of the third duration threshold, data to be evaluated with the same time span can be intercepted from the first base station before the cutover and the second base station after the cutover for comparison, and the difference between the first data to be evaluated of the first base station and the second data to be evaluated of the second base station under the same time span is determined, and then the difference is compared with the corresponding first abnormal difference condition to determine whether the difference meets the first abnormal difference condition, and the base station cutover quality is further evaluated according to the judgment result.

[0065] Optionally, the third duration threshold may be 3 days.

[0066] The present invention also provides a preferred embodiment, which provides an automated base station cutover quality assessment method based on a nine-dimensional three-dimensional assessment system. By actively supervising the cutover process and assessing the cutover quality, it helps to promptly discover problems in the cutover process, promptly repair abnormal cutover cells, and promptly improve the cutover process.

[0067] It should be noted that existing base station cutover projects generally passively discover problems in base station cutover through user complaints, network management alarms, etc., and do not actively monitor the quality of base station cutover. The nine-dimensional three-dimensional automated evaluation method for evaluating the quality of base station cutover proposed in this application helps to achieve a closed loop of project implementation-quality evaluation-result feedback-project optimization, and improve the quality and efficiency of base station cutover.

[0068] As an optional embodiment, a base station cutover quality automatic evaluation method based on a nine-dimensional three-dimensional evaluation system uses a big data platform as a data source, and judges whether the cell cutover is abnormal from fifteen indicators in nine dimensions, such as the cutover duration, total business volume, performance indicators, and perception rate, in three periods: at that time, one day, and three days, and automatically outputs an evaluation report, which specifically includes the following steps:

[0072] Alternatively, if Figure 3 As shown, the quality assessment at the time of cutover is based on the dimension of cutover site disconnection, the site disconnection duration caused by the cutover project is counted, and the cell with a cutover site disconnection duration exceeding is determined as an abnormal cutover cell.

The above fourteen indicators are checked. When the cutover behavior results in an indicator that exceeds the specified change threshold, the cell is judged as an abnormal cutover cell.

[0074] Alternatively, if Figure 3 As shown in FIG. 1 , the quality assessment dimensions and indicators for three days after cutover are consistent with those for one day after connection. The difference is that the indicators for monitoring within one day after cutover are changed to those for monitoring within three days after cutover.

[0075] Step S23, abnormal cell determination.

[0076] Table 1 is a schematic table for setting an abnormal threshold for each indicator under the evaluation dimension. As shown in Table 1, after obtaining the cutover cell indicator based on the method of step S22 above, the abnormal threshold can be set according to the reference value in Table 1, and the cell whose indicator reaches the abnormal threshold is determined to be a cutover abnormal cell.
