Description

Technical Field

[0001] This application relates to the field of communication technology, and in particular to a signal analysis method, device and storage medium for a 4G network indoor distribution system. Background Technology

[0002] As the co-construction and sharing efforts of multiple operators deepen, their 5G networks are being built under a "single network" model. However, prior to this co-construction and sharing, each operator had already built a massive 4G network, with many base stations and indoor distributed antenna systems (DAS) overlapping and covering the same sites and buildings. Therefore, with the rapid development of networks towards 5G, the 4G networks of each operator also need to be integrated towards a "single network." Integrating the 4G networks of both parties into a "single network" is an important measure to implement the "dual-carbon" strategy and effectively reduce operating costs such as electricity and rental fees for both parties. From the perspectives of network technology and traffic volume, indoor distributed antenna systems (DAS) are the priority for integration. For buildings where each operator has already built an indoor DAS, it is necessary to select the best-quality DAS to carry the services of both parties. Therefore, signal analysis of the indoor DAS quality of each operator is required first.

[0003] Current technologies primarily employ manual testing methods such as drive testing (DT) or call quality testing (CQT) to conduct comprehensive testing. Alternatively, network statistical analysis methods, such as comparing measurement reports (MR), can be used to measure the overall signal coverage of the indoor distribution system, further facilitating the integration of indoor distribution systems from multiple operators.

[0004] However, due to limitations in testing area and testing methods, indoor distribution systems may experience low measurement efficiency and inaccurate measurement results. Summary of the Invention

[0072] The accompanying drawings have illustrated specific embodiments of this application, which will be described in more detail below. These drawings and descriptions are not intended to limit the scope of the concept in any way, but rather to illustrate the concept of this application to those skilled in the art through reference to specific embodiments. Detailed Implementation

[0073] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0074] Current technologies primarily employ manual testing methods such as drive testing (DT) or call quality testing (CQT) to conduct comprehensive testing of indoor distribution systems. Measurement report (MR) comparisons and other network statistical analyses can also be used to measure the overall signal coverage of indoor distribution systems, further facilitating the integration of multi-carrier indoor distribution systems. However, due to limitations in testing areas and methods, issues such as low measurement efficiency and inaccurate results arise.

[0075] This application identifies indoor distributed antenna systems (DAS) within the analysis area, dividing them into a first DAS and a second DAS. It collects the corresponding operating parameter data for each DAS within the analysis area. Based on the operating parameter data, it sends inter-frequency signal measurement commands to the first DAS and collects the measurement report (MR) data of the first DAS. The inter-frequency signal measurement commands instruct the first DAS to initiate inter-frequency signal measurements. Based on the operating parameter data, it parses the MR data of the first DAS to obtain inter-frequency signal measurement data, which includes signal strength measurement data for both the first and second DAS. This inter-frequency signal measurement method improves the efficiency of the 4G network DAS signal analysis method by collecting signal strength data from each DAS within the analysis area. The inter-frequency signal measurement data of the first DAS is input into the DAS signal analysis model to perform signal analysis on the DAS within the analysis area. The DAS signal analysis model provided in this embodiment employs a single-point inter-operator comparative evaluation strategy and considers the variability of the reach threshold, thus improving the accuracy of the 4G network DAS signal analysis method.

[0076] The technical solution of this application and how the technical solution of this application solves the above-mentioned technical problems are described in detail below with specific embodiments. These specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments. The embodiments of this application will be described below with reference to the accompanying drawings.

[0077] Figure 1 This is a flowchart illustrating the signal analysis method for a 4G network indoor distribution system provided in the first embodiment of this application.

[0078] like Figure 1 As shown, the signal analysis method for the 4G network indoor distribution system in this embodiment may include the following steps:

[0079] Step S101: Determine the indoor distribution system in the area to be analyzed. The indoor distribution system is divided into a first indoor distribution system and a second indoor distribution system. The first indoor distribution system and the second indoor distribution system are indoor distribution systems of different operators.

[0080] Among them, the indoor distributed antenna system, also known as the indoor passive distributed antenna system, is a solution used to improve the mobile communication environment inside buildings. Its principle is to distribute the signal of the mobile communication base station evenly to every corner of the room through various indoor antennas, thereby ensuring ideal signal coverage in the indoor area.

[0081] Specifically, the area to be analyzed, for example, a building, may include indoor distribution systems from two operators. The signal analysis method for the 4G network indoor distribution system of this application can analyze the signal quality of the indoor distribution systems of two operators within the area to be analyzed. Therefore, it is necessary to first confirm the indoor distribution systems within the area to be analyzed and determine the first and second indoor distribution systems. The first and second indoor distribution systems correspond to different operators, with the operator corresponding to the first indoor distribution system being the operator that initiated the signal analysis process of the 4G network indoor distribution system in this embodiment.

[0082] Optionally, the area to be analyzed may include indoor distribution systems of more than two operators. The process of analyzing the signal quality of the indoor distribution systems of the two operators in the area to be analyzed can refer to the process of analyzing the signal quality of the indoor distribution systems of the two operators in the area to be analyzed in this embodiment.

[0083] Step S102: Collect the operating parameter data corresponding to the indoor distribution system in the area to be analyzed.

[0084] Each indoor distribution system within the area to be analyzed can be composed of a certain number of indoor distribution cells. An indoor distribution cell refers to the smallest unit of an indoor distribution system that has one or more base station devices. Figure 2 This is an example diagram showing the distribution of indoor cells in an indoor passive distributed antenna system.

[0085] Specifically, operational parameter data can be collected from the indoor distributed antenna system (DAS) within the area to be analyzed, specifically the first and second DAS systems. This operational parameter data refers to the operational parameters of the indoor DAS cells, which may include: cell base station identifier (EnodeBID), cell identifier (PCI), and carrier frequency number (EARFCN). The EnodeBID identifies the base station equipment of the indoor DAS cell, i.e., the source device. The PCI identifies the indoor DAS cell. The carrier frequency number (E-UTRA Absolute Radio Frequency Channel Number, EARFCN) is the absolute radio frequency channel number, represented by 16 bits, ranging from 0 to 65535. Within the same building, the EARFCN for the same operator is generally uniform, while the EARFCN for different operators is different.

[0086] Step S103: Based on the engineering parameter data, send a frequency signal measurement command to the first indoor distribution system and collect the measurement report MR data of the first indoor distribution system. The frequency signal measurement command is used to instruct the indoor distribution system to initiate frequency signal measurement.

[0087] Inter-frequency measurement refers to the process of measuring the signal strength of multiple carrier frequency points in the area to be measured, initiated by the measuring party. Inter-frequency measurement is a periodic measurement initiated at a certain time, such as ten milliseconds.

[0088] Specifically, based on the engineering parameter data collected in step S102, an inter-frequency signal measurement command can be sent to the first indoor distribution system described in step S101. The inter-frequency signal measurement command is used to instruct the first indoor distribution system to initiate inter-frequency signal measurement. The inter-frequency signal measurement command may include information such as the measurement period of the inter-frequency signal measurement, the cell base station flag, and the carrier frequency point number.

[0089] Specifically, after receiving the inter-frequency signal measurement command, the first indoor distributed antenna system can initiate inter-frequency measurement. The indoor distributed antenna system can be composed of a certain number of indoor distributed antenna cells, and each indoor distributed antenna cell can cover multiple user terminals. Specifically, based on the engineering parameter data, the first indoor distributed antenna system can send the inter-frequency signal measurement command to the first indoor distributed antenna system. The base station equipment of each indoor distributed antenna cell of the first indoor distributed antenna system can send the command to the multiple user terminals covered by the multiple indoor distributed antenna cells, and each user terminal initiates inter-frequency measurement according to the above command.

[0090] Specifically, after the inter-frequency measurement is completed, the measurement report MR data of the first indoor distribution system can be collected from, for example, the northbound network port of the network management system. The collected measurement report MR data of the first indoor distribution system includes the inter-frequency signal measurement data of the first indoor distribution system.

[0091] Step S104: Based on the engineering parameter data, analyze the measurement report MR data of the first indoor distribution system to obtain the inter-frequency signal measurement data of the first indoor distribution system. The inter-frequency signal measurement data includes the signal strength measurement data of the first indoor distribution system and the second indoor distribution system.

[0092] As described in step S103, the acquired measurement report (MR) data of the first indoor distribution system includes inter-frequency signal measurement data of the first indoor distribution system. Based on the engineering parameter data acquired in step S102, the measurement report (MR) data of the first indoor distribution system acquired in step S103 can be analyzed to obtain the inter-frequency signal measurement data of the first indoor distribution system. This inter-frequency signal measurement data includes signal strength measurement data of both the first and second indoor distribution systems. Specifically, the inter-frequency signal measurement data of the first indoor distribution system refers to the signal strength measurement data of both the first and second indoor distribution systems obtained when the first indoor distribution system initiates inter-frequency measurement.

[0093] Specifically, as described in step S103, each indoor distributed antenna system (DAS) cell can cover multiple user terminals. The parsed measurement report (MR) data, i.e., the inter-frequency signal measurement data of the first indoor DAS system, can include: a timestamp (TimeStamp), a user ID (MmeUe1apId), the signal strength (MR.LteScRSRP) of the initiating measurement cell, the frequency (MR.LteScEarfcn) of the initiating measurement cell, the identifier (MR.LteScPci) of the initiating measurement cell, the signal strength (MR.LteNcRSRP) of the neighboring cell to be measured, the frequency (MR.LteNcEarfcn) of the neighboring cell to be measured, and the identifier (MR.LteNcPci) of the neighboring cell to be measured. The initiating measurement cell refers to the indoor DAS cell where the user terminal initiating the inter-frequency signal measurement is located, and its related information is the signal strength measurement data of the first indoor DAS system. The neighboring cell to be measured refers to the indoor DAS cell in the second indoor DAS system adjacent to the aforementioned initiating measurement cell, and its related information is the signal strength measurement data of the second indoor DAS system. The signal strength of the cell initiating the measurement refers to the signal strength of the base station equipment of the cell initiating the measurement at the location of a user terminal with a certain user number during a certain inter-frequency measurement process. The signal strength of the neighboring cell to be measured refers to the signal strength of the base station equipment of the neighboring cell to be measured at the location of a user terminal with a certain user number during a certain inter-frequency measurement process.

[0094] Optionally, during the inter-frequency measurement process described in step S103, if an event-related measurement occurs simultaneously, the inter-frequency measurement cannot be initiated. Event-related measurements refer to other measurements unrelated to the inter-frequency measurement, such as measurements caused by events like a user temporarily entering the network or a user initiating a call. Correspondingly, the parsed inter-frequency signal measurement data of the first indoor distribution system may have missing data such as the signal strength of the adjacent cells to be measured. During the parsing process, entire segments of the inter-frequency signal measurement data of the first indoor distribution system that lack the signal strength of the adjacent cells to be measured at a specific timestamp for a particular user can be deleted to improve the accuracy of the inter-frequency signal measurement data of the first indoor distribution system.

[0095] Optionally, during the inter-frequency measurement process described in step S103, if the user terminal is not a full-network compatible user terminal, the inter-frequency measurement cannot be initiated. A full-network compatible user refers to a mobile terminal user that supports all operators. As described above, during the parsing process, the entire inter-frequency signal measurement data of the first indoor distribution system that lacks signal strength data of a specific user at a specific timestamp can be deleted to improve the accuracy of the inter-frequency signal measurement data of the first indoor distribution system.

[0096] Optionally, special configuration information refers to the special configuration information related to the source equipment of the indoor distributed antenna system (DAS) cell, i.e., the base station equipment. Special configuration information data may include: equipment power, power offset, channel attenuation, special reference power, etc. The special configuration information is the same for the same indoor DAS cell, but may differ for the source equipment of different indoor DAS cells. Therefore, during the parsing process, the special configuration information data of the initiating measurement cell and the adjacent cells to be measured can be compared. If there are differences in the special configuration information data between the two, the inter-frequency signal measurement data of the first indoor DAS system can be processed through certain methods, such as data compensation, to eliminate problems such as equipment output power gain caused by special configuration, thereby improving the accuracy of the inter-frequency signal measurement data of the first indoor DAS system.

[0097] Step S105: Input the inter-frequency signal measurement data of the first indoor distribution system into the indoor distribution system signal analysis model, and perform signal analysis on the indoor distribution system in the area to be analyzed.

[0098] Specifically, the inter-frequency signal measurement data of the first indoor distribution system obtained in step S104 can be input into the indoor distribution system signal analysis model to perform signal analysis on the indoor distribution system within the area to be analyzed. The indoor distribution system signal analysis model is a model constructed in this application for performing signal analysis on the indoor distribution system within the area to be tested based on the inter-frequency signal measurement data of the first indoor distribution system.

[0099] Specifically, a single-point inter-operator comparison evaluation strategy can be adopted as the indoor distributed system (DPS) evaluation strategy for the signal analysis model of the DPS system in this application. Specifically, the single-point inter-operator comparison evaluation strategy compares the signal strength of the adjacent cell to be measured with the signal strength of the initiating measurement cell in the sample data of each point measured by the initiating measurement cell (i.e., the location of the user terminal). If the difference is within an acceptable range (i.e., provided that the user's perception does not decrease), then the DPS system quality at that point is determined to be comparable. For example, for the inter-frequency signal measurement data of the first DPS system described in step S104, based on the timestamp and user number, the signal strength MR.LteScRSRP of the initiating measurement cell and the signal strength MR.LteNcRSRP of the adjacent cell to be measured for each user terminal within the DPS cell can be extracted. The difference between the signal strength of the initiating measurement cell and the signal strength of the adjacent cell to be measured can be calculated, and the quality of the first and second DPS systems can be judged based on this difference.

[0100] As described above regarding the inter-operator comparison and evaluation strategy for a single location, if the difference is within an acceptable range (i.e., provided that the user's perception does not degrade), then the distribution system quality of both locations is considered equivalent. In this embodiment, the acceptable range of the difference, i.e., the compliance threshold, can be set as a variable elastic value. Optionally, the compliance threshold can be adjusted based on the signal strength of the initiating measurement cell. The better the signal of the initiating measurement cell, the larger the acceptable range of the signal strength of the adjacent cell to be measured, i.e., the compliance threshold, will be; the two are non-linearly correlated. Table 1 provides an example table of compliance threshold values ​​provided in this embodiment.

[0101] Table 1

[0102]

[0103] Among them, the threshold for achieving the target is related to the signal strength MR.LteScRSRP of the cell initiating the measurement. Figure 3 This is a graph showing the relationship between the signal strength MR.LteScRSRP of the cell initiating the measurement and the compliance threshold value.

[0104] Specifically, the indoor distribution system signal analysis model can perform signal analysis on the quality of the indoor distribution system in the area to be analyzed based on the correspondence between the signal strength MR.LteScRSRP of the initiating measurement cell and the compliance threshold value in Table 1, combined with the inter-frequency signal measurement data parsed in step S104.

[0105] Optionally, the indoor distribution systems within the area to be analyzed can be selected and integrated based on the signal analysis results of the indoor distribution systems within the area to be analyzed.

[0106] The signal analysis method for a 4G network indoor distribution system provided in this embodiment determines the indoor distribution systems within the analysis area. These indoor distribution systems are divided into a first indoor distribution system and a second indoor distribution system. The method collects the corresponding operating parameter data for each indoor distribution system within the analysis area. Based on the operating parameter data, a cross-frequency signal measurement command is sent to the first indoor distribution system, and the measurement report (MR) data of the first indoor distribution system is collected. The cross-frequency signal measurement command instructs the first indoor distribution system to initiate cross-frequency signal measurement. Based on the operating parameter data, the MR data of the first indoor distribution system is parsed to obtain the cross-frequency signal measurement data of the first indoor distribution system. The cross-frequency signal measurement data includes signal strength measurement data for both the first and second indoor distribution systems. The method of collecting signal strength data for each indoor distribution system within the analysis area through cross-frequency signal measurement improves the efficiency of the 4G network indoor distribution system signal analysis method. The inter-frequency signal measurement data of the first indoor distribution system is input into the indoor distribution system signal analysis model to perform signal analysis on the indoor distribution system in the area to be analyzed. The indoor distribution system signal analysis model provided in this embodiment uses a single-point inter-operator comparison and evaluation strategy and considers the variability of the target threshold, which improves the accuracy of the signal analysis method of the 4G network indoor distribution system.

[0107] Figure 4 This is a flowchart illustrating the process of inputting inter-frequency signal measurement data from the first indoor distribution system into the indoor distribution system signal analysis model, as provided in the second embodiment of this application, to perform signal analysis on the indoor distribution system within the analysis area. Figure 1 Based on the embodiments, the indoor distribution system signal analysis model includes: a building-level indoor distribution system signal analysis model, a community-level indoor distribution system signal analysis model, and a coverage edge area indoor distribution system signal analysis model. The area to be analyzed includes: the building to be analyzed or the community to be analyzed. This embodiment describes in detail the process of inputting the inter-frequency signal measurement data of the first indoor distribution system into the indoor distribution system signal analysis model and performing signal analysis on the indoor distribution system in the area to be analyzed.

[0108] like Figure 4 As shown, in this embodiment, the measurement data of the different frequency signals of the first indoor distribution system are input into the indoor distribution system signal analysis model. The signal analysis of the indoor distribution system in the area to be analyzed may include the following steps:

[0109] Step S401: Input the heterogeneous frequency signal measurement data of the first indoor distribution system into the building-level indoor distribution system signal analysis model to obtain the building homogeneity rate of the first indoor distribution system.

[0110] The indoor distributed antenna system (DAS) signal analysis models include: building-level DAS signal analysis model, cell-level DAS signal analysis model, and coverage edge area DAS signal analysis model. The areas to be analyzed include: the buildings or cells to be analyzed. By stratifying the areas to be analyzed and combining the above three DAS signal analysis models, signal analysis can be performed on the DAS systems within the areas to be analyzed.

[0111] Specifically, the measurement data of the different frequency signals of the first indoor distribution system obtained in step S104 can be input into the building-level indoor distribution system signal analysis model to obtain the building homogeneity rate of the first indoor distribution system.

[0112] Specifically, a building-level indoor distribution system signal analysis model can be constructed based on the single-point inter-operator comparison and evaluation strategy described in step S105. This model allows for a comprehensive benchmarking analysis of all indoor distribution cells within multiple indoor distribution systems in the building under analysis. For a user terminal in the cell initiating the measurement, if the signal strength of any adjacent cell meets the threshold requirement, the signal quality of the first and second indoor distribution systems at the user terminal's location is considered equivalent.

[0113] Specifically, the building homogeneity rate can be used as the evaluation criterion for the signal analysis model of a building-level indoor distribution system. The expression for the building homogeneity rate is as follows:

[0114]

[0115] The sum of user measurement counts for each measurement cell refers to the total frequency of inter-frequency measurements initiated by all user terminals under all indoor distribution cells of the first indoor distribution system in the building to be analyzed during the measurement period. A single user terminal may initiate multiple inter-frequency measurements at regular intervals during the measurement period, but a single user terminal can only initiate one inter-frequency measurement at the same timestamp.

[0116] The sum of the number of times the MR.LteNcRSRP value of the adjacent cells to be measured meets the standard is the sum of the number of times the signal strength MR.LteNcRSRP of the adjacent cells to be measured meets the standard under all user terminals in all indoor distributed cells of the first indoor distributed system in the building to be analyzed during the measurement period. In this process, when a user terminal in a cell of the first indoor distribution system within the building under analysis initiates an inter-frequency measurement, if it measures the signal strength MR.LteNcRSRP of one or more adjacent cells of the second indoor distribution system within the building under analysis, the optimal value of the signal strength MR.LteNcRSRP of the adjacent cells to be measured is selected and compared with the signal strength MR.LteScRSRP of the cell initiating the measurement. If the difference between the optimal value of the signal strength MR.LteScRSRP of the initiating measurement cell and the optimal value of the signal strength MR.LteNcRSRP of the adjacent cells to be measured is less than a threshold, the number of times the signal strength MR.LteNcRSRP of the adjacent cells to be measured meets the standard is recorded as 1. If the difference is greater than or equal to the threshold value, the number of times the signal strength MR.LteNcRSRP of the adjacent cells to be measured meets the standard is recorded as 0. If the signal strength MR.LteNcRSRP of the adjacent cells to be measured in the second indoor distribution system within the building under analysis is not measured, the number of times the signal strength MR.LteNcRSRP of the adjacent cells to be measured meets the standard is also recorded as 0. Within a single timestamp, when the same user terminal initiates an inter-frequency measurement, the maximum number of times the signal strength MR.LteNcRSRP of the adjacent cell to be measured meets the standard is recorded as 1. The value of the standard threshold is as described in step S105.

[0117] Among them, the building homogeneity rate, that is, the building distribution system homogeneity rate is less than 1, can be specifically obtained by inputting the inter-frequency signal measurement data of the first indoor distribution system into the building-level indoor distribution system signal analysis model and outputting the building homogeneity rate of the first indoor distribution system. The closer the building homogeneity rate of the first indoor distribution system is to 1, the closer the signal quality of the second indoor distribution system is to the first indoor distribution system, and the closer the coverage range of the two is to the same. The smaller the building homogeneity rate, the worse the signal quality of the second indoor distribution system, and the smaller the overlap of the coverage range of the two.

[0118] Specifically, a building homogeneity rate threshold can be set to determine the signal quality relationship between the first and second indoor distributed antenna system (DAS). For example, when the building homogeneity rate of the first DAS is higher than the threshold, the signal quality of the first and second DAS is comparable; when the building homogeneity rate of the first DAS is lower than the threshold, the signal quality of the first DAS is superior to that of the second DAS. The value of the building homogeneity rate threshold can be set according to the operator's requirements for the signal quality of the DAS.

[0119] Step S402: When the building homogeneity rate of the first indoor distribution system is higher than the building homogeneity rate threshold, perform signal analysis on the indoor distribution system of the building to be analyzed based on the completion status of the building bidirectional signal analysis.

[0120] Specifically, the building homogeneity rate of the first indoor distribution system can be determined according to the building homogeneity rate threshold described in step S401. When the building homogeneity rate of the first indoor distribution system is higher than the building homogeneity rate threshold, as described in step S401, the signal quality of the first indoor distribution system and the second indoor distribution system are comparable. At this time, it is necessary to perform signal analysis on the indoor distribution system of the building to be analyzed based on the completion status of the building bidirectional signal analysis, that is, to analyze the signal quality of each indoor distribution system in the analysis area from the perspective of the second indoor distribution system.

[0121] The building bidirectional signal analysis involves each indoor distribution system within the test area responding to the inter-frequency signal measurement command sent by the signal analysis device of the 4G network indoor distribution system of this application, and obtaining the building homogeneity rate. The building homogeneity rate of the second indoor distribution system can be calculated using the building-level indoor distribution system signal analysis model proposed in this application, or it can be calculated using the building homogeneity rate calculation method proprietary to the operator of the second indoor distribution system.

[0122] The completion status of building two-way signal analysis includes: building two-way signal analysis completed and building two-way signal analysis not completed.

[0123] Specifically, when the building two-way signal analysis is incomplete, a cross-frequency signal measurement command is sent to the second indoor distribution system. Based on the response of the second indoor distribution system to the cross-frequency signal measurement command, signal analysis is performed on the indoor distribution system of the building to be analyzed.

[0124] When the second indoor distribution system receives the inter-frequency signal measurement command sent by the signal analysis device of the 4G network indoor distribution system of this application, two situations may occur: it responds to the command, i.e., the second indoor distribution system initiates inter-frequency measurement; or it does not respond to the command, i.e., the second indoor distribution system does not initiate inter-frequency measurement. Specifically, signal analysis of the indoor distribution system of the building to be analyzed can be performed based on the response of the second indoor distribution system to the inter-frequency signal measurement command described above.

[0125] Specifically, when the building two-way signal analysis is completed, the building homogeneity rate of the second indoor distribution system is obtained, and the signal analysis of the indoor distribution system of the building to be analyzed is performed based on the building homogeneity rate of the second indoor distribution system.

[0126] The building homogeneity rate of the second indoor distribution system can be calculated using the building-level indoor distribution system signal analysis model proposed in this application, or it can be calculated using the building homogeneity rate calculation method owned by the operator of the second indoor distribution system.

[0127] Step S403: When the building homogeneity rate of the first indoor distribution system is lower than the building homogeneity rate threshold, perform signal analysis on the indoor distribution system of the community to be analyzed according to the community-level indoor distribution system signal analysis model.

[0128] Specifically, the building homogeneity rate of the first indoor distribution system can be determined according to the building homogeneity rate threshold described in step S401. When the building homogeneity rate of the first indoor distribution system is lower than the building homogeneity rate threshold, as described in step S401, the signal quality of the first indoor distribution system is better than the signal quality of the second indoor distribution system. At this time, the signal analysis of the indoor distribution system of the cell to be analyzed can be performed according to the cell-level indoor distribution system signal analysis model, that is, the signal quality of each indoor distribution system in the cell to be analyzed is analyzed at the cell level.

[0129] Specifically, a cell-level indoor distribution system signal analysis model can be constructed based on the single-point inter-operator comparison and evaluation strategy described in step S105, so as to perform signal analysis on the quality of the indoor distribution system of the cell to be analyzed.

[0130] Specifically, the signal analysis model for a cell-level indoor distribution system can use the cell homogeneity rate as the evaluation criterion for the system. The expression for the cell homogeneity rate is as follows:

[0131]

[0132] In this context, the initiating measurement cell S1 is the cell to be analyzed. The sum of the number of user measurements in the initiating measurement cell S1 refers to the cell to be analyzed in the first indoor distribution system, that is, the total frequency of all user terminals initiating inter-frequency measurements under the initiating measurement cell S1 during the measurement period. A single user terminal can only initiate one inter-frequency measurement at the same timestamp.

[0133] The sum of the number of times the signal strength of the adjacent cells to be measured meets the standard is the sum of the number of times the signal strength MR.LteNcRSRP of the adjacent cells to be measured is met by all user terminals in the cell to be analyzed during the measurement period for all inter-frequency measurements. Specifically, if a user terminal in the cell to be analyzed measures the signal strength MR.LteNcRSRP of one or more adjacent cells in the second indoor distribution system of the cell to be analyzed while initiating an inter-frequency measurement, the optimal value of the signal strength MR.LteNcRSRP of the adjacent cell to be measured is selected and compared with the signal strength MR.LteScRSRP of the initiating measurement cell S1. If the difference between the signal strength MR.LteScRSRP of the initiating measurement cell S1 and the optimal value of the signal strength MR.LteNcRSRP of the adjacent cell to be measured is less than the standard threshold, the number of times the signal strength MR.LteNcRSRP of the adjacent cell to be measured meets the standard is recorded as 1. If the difference is greater than or equal to the threshold value, the number of times the signal strength MR.LteNcRSRP of the adjacent cell to be measured meets the standard is recorded as 0. If the signal strength MR.LteNcRSRP of the adjacent cell to be measured in the second indoor distribution system of the building to be analyzed is not measured, the number of times the signal strength MR.LteNcRSRP of the adjacent cell to be measured meets the standard is also recorded as 0. When the same user terminal initiates an inter-frequency measurement, that is, within one timestamp, the number of times the signal strength MR.LteNcRSRP of the adjacent cell to be measured meets the standard is recorded at most 1. The value of the standard threshold is as described in step S105.

[0134] The cell homogeneity rate, or the homogeneity rate of the cell distribution system, is a value less than 1. Specifically, as described in step S102, each indoor distribution system within the area to be analyzed can be composed of a certain number of indoor distribution cells. Therefore, the building to be analyzed includes multiple cells. The inter-frequency signal measurement data of the first indoor distribution system can be input into the cell-level indoor distribution system signal analysis model to output multiple building homogeneity rates of the first indoor distribution system. The closer the cell homogeneity rate is to 1, the closer the quality of the second indoor distribution system within that cell is to the first indoor distribution system, and the closer their coverage areas are to being consistent. The smaller the cell homogeneity rate, the worse the quality of the second indoor distribution system within that cell, and the smaller the overlap in their coverage areas.

[0135] Specifically, a cell homogeneity rate threshold can be set to determine the signal quality relationship between the first and second indoor distributed antenna system (DAS). For example, when the cell homogeneity rate of the first DAS is higher than the threshold, the signal quality of the first and second DAS is comparable within that cell range. Conversely, when the cell homogeneity rate of the first DAS is lower than the threshold, the signal quality of the first DAS is superior to that of the second DAS within that cell range. The value of the cell homogeneity rate threshold can be set according to the operator's requirements for the signal quality of the DAS.

[0136] Specifically, the inter-frequency signal measurement data of the first indoor distribution system is input into the cell-level indoor distribution system signal analysis model to obtain the cell homogeneity rate of the first indoor distribution system.

[0137] As described above, the first indoor distribution system includes multiple indoor distribution cells. Therefore, after inputting the inter-frequency signal measurement data of the first indoor distribution system into the cell-level indoor distribution system signal analysis model, the cell homogeneity rate of multiple first indoor distribution systems can be obtained.

[0138] When the cell homogeneity rate of the first indoor distribution system is lower than the cell homogeneity rate threshold, the signal quality of the first indoor distribution system of the cell to be analyzed is better.

[0139] Specifically, the cell homogeneity rate of the first indoor distribution system can be judged based on the cell homogeneity rate threshold described above. When the cell homogeneity rate of the first indoor distribution system is lower than the cell homogeneity rate threshold, as described above, within the range of the indoor distribution cell, the signal quality of the first indoor distribution system is better than that of the second indoor distribution system, that is, the signal quality of the first indoor distribution system in the cell to be analyzed is better.

[0140] When the cell homogeneity rate of the first indoor distribution system is higher than the cell homogeneity rate threshold, signal analysis is performed on the indoor distribution system of the cell to be analyzed based on the completion status of the bidirectional signal analysis.

[0141] Specifically, the cell homogeneity rate of the first indoor distribution system can be determined based on the cell homogeneity rate threshold described above. When the cell homogeneity rate of the first indoor distribution system is higher than the cell homogeneity rate threshold, as described above, within the range of the indoor distribution cell and within the range of the cell initiating the measurement, the signal quality of the first indoor distribution system and the second indoor distribution system are comparable. In this case, it is necessary to perform signal analysis on the indoor distribution system of the cell to be analyzed based on the completion status of the bidirectional signal analysis, that is, to analyze the signal quality of each indoor distribution system in the area to be analyzed from the perspective of the second indoor distribution system.

[0142] The cell bidirectional signal analysis involves each indoor distribution system within the test area responding to the inter-frequency signal measurement command sent by the signal analysis device of the 4G network indoor distribution system of this application, and obtaining the cell homogeneity rate. The cell homogeneity rate of the second indoor distribution system can be calculated using the cell-level indoor distribution system signal analysis model proposed in this application, or it can be calculated using the operator's proprietary cell homogeneity rate calculation method for the second indoor distribution system.

[0143] This embodiment provides a process of inputting inter-frequency signal measurement data from the first indoor distribution system into the indoor distribution system signal analysis model, and performing signal analysis on the indoor distribution system within the analysis area. The indoor distribution system signal analysis model is divided into building-level and cell-level models, and the analysis area is divided into either the building to be analyzed or the cell to be analyzed. By using different levels of signal analysis models and performing layered analysis on the analysis area, the accuracy of the signal analysis method for 4G network indoor distribution systems is improved.

[0144] Figure 5 This is a flowchart illustrating the signal analysis of the indoor distribution system of the building to be analyzed based on the response of the second indoor distribution system to the measurement command of the inter-frequency signal, as provided in the third embodiment of this application. Figure 4 Based on the previous embodiment, this embodiment describes in detail the process of performing signal analysis on the indoor distribution system of the building to be analyzed according to the response of the second indoor distribution system to the measurement command of the different frequency signal.

[0145] like Figure 5 As shown, the signal analysis of the building's indoor distribution system based on the response of the second indoor distribution system to the measurement command for the inter-frequency signal in this embodiment may include the following steps:

[0146] Step S501: When the second indoor distribution system responds to the measurement command of the different frequency signal, the building homogeneity rate of the second indoor distribution system is collected.

[0147] Specifically, as described in step S402, when the second indoor distribution system receives the inter-frequency signal measurement command sent by the signal analysis device of the 4G network indoor distribution system of this application, there are two possible scenarios: responding to the command, i.e., the second indoor distribution system initiates inter-frequency measurement, or not responding to the command, i.e., the second indoor distribution system does not initiate inter-frequency measurement.

[0148] When the second indoor distribution system responds to the inter-frequency signal measurement command, the second indoor distribution system initiates inter-frequency measurement. At this time, the building homogeneity rate of the second indoor distribution system can be collected.

[0149] Optionally, when the second indoor distribution system receives the inter-frequency signal measurement command sent by the signal analysis device of the 4G network indoor distribution system of this application, it can calculate the building homogeneity rate of the second indoor distribution system using the building homogeneity rate calculation method owned by the operator of the second indoor distribution system.

[0150] Step S502: When the second indoor distribution system does not respond to the measurement command for the different frequency signal, perform signal analysis on the indoor distribution system of the building to be analyzed according to the signal analysis model of the indoor distribution system in the coverage edge area.

[0151] When the second indoor distribution system does not respond to the inter-frequency signal measurement command, the second indoor distribution system does not initiate inter-frequency measurement. In this case, the signal analysis of the indoor distribution system of the building to be analyzed can be performed based on the signal analysis model of the indoor distribution system in the coverage edge area.

[0152] In the actual measurement process of the indoor distribution system, there may be a situation where the second indoor distribution system does not respond to the measurement command of the inter-frequency signal, that is, the homogeneity rate of the second indoor distribution system cannot be obtained. Therefore, a signal analysis model of the indoor distribution system in the coverage edge area can be constructed according to the single-point inter-operator comparison evaluation strategy described in step S301, so as to perform signal analysis on the quality of the indoor distribution system in the coverage edge area of ​​the first indoor distribution system in the area to be analyzed.

[0153] Specifically, the signal analysis model for indoor distribution systems in coverage edge areas can use excellent coverage rate as the evaluation criterion for indoor distribution systems in coverage edge areas of the first indoor distribution system. The expression for excellent building coverage rate is as follows:

[0154]

[0155] The sum of user measurements initiated when the signal strength of the cell initiating the measurement is below the edge threshold refers to the total frequency of inter-frequency measurements initiated by all user terminals within the edge coverage area of ​​all indoor distributed antenna system (DAS) cells in the building under analysis during the measurement period. Whether a user terminal is in the edge coverage area is determined by the signal strength of the cell initiating the measurement. When a user terminal initiates an inter-frequency measurement, if the signal strength of the cell initiating the measurement is below the edge threshold, the user terminal is considered to be in the edge coverage area of ​​the indoor DAS cell. The edge threshold, also known as the weak coverage threshold, refers to the lowest acceptable signal strength of the indoor DAS cell, which can be set by each operator according to their own needs.

[0156] The sum of the number of times the signal strength of the adjacent cell to be measured is better refers to the sum of the number of times the signal strength of the adjacent cell to be measured is better under the coverage edge of all user terminals under the coverage edge of all indoor distributed antenna systems (DAS) of the first indoor distributed antenna system in the building to be analyzed during all inter-frequency measurements. Specifically, the number of times the signal strength of the adjacent cell to be measured is better refers to the number of times, during an inter-frequency measurement, the signal strength MR.LteNcRSRP of the adjacent cell to be measured is higher than the signal strength MR.LteScRSRP of the initiating measurement cell by a certain range, for example, 3dB. The difference between the signal strength MR.LteNcRSRP of the adjacent cell to be measured and the signal strength MR.LteScRSRP of the initiating measurement cell can be set according to the actual needs of the operator.

[0157] Among them, the building coverage rate, that is, the excellent coverage rate of the distribution system in the building coverage edge area, is a value less than 1. The closer the building coverage rate of the indoor distribution system is to 1, the better the coverage of the indoor distribution system of the adjacent community to be measured in the building coverage edge area.

[0158] Specifically, a building coverage threshold can be set to determine the signal quality of each indoor distributed antenna system (DAS) at the coverage edge area. When the building coverage rate of an indoor DAS is higher than the threshold, the signal quality of the DAS corresponding to the neighboring cell being measured is better than that of the cell initiating the measurement. When the building coverage rate is lower than the threshold, the signal quality of the DAS corresponding to the neighboring cell being measured is comparable to that of the cell initiating the measurement. The building coverage threshold can be set according to the operator's requirements for the signal quality of the indoor DAS.

[0159] Specifically, the inter-frequency signal measurement data of the first indoor distribution system is input into the signal analysis model of the indoor distribution system in the coverage edge area to obtain the building coverage rate of the first indoor distribution system. When the building coverage rate of the first indoor distribution system is higher than the building coverage rate threshold, the signal quality of the second indoor distribution system in the building under analysis is better. When the building coverage rate of the first indoor distribution system is lower than the building coverage rate threshold, the quality of the first and second indoor distribution systems in the building under analysis is comparable.

[0160] This embodiment provides a process for signal analysis of the indoor distribution system of the building to be analyzed based on the response of the second indoor distribution system to the measurement command of the inter-frequency signal. By using the signal analysis model of the indoor distribution system in the coverage edge area, the signal quality of the indoor distribution system in the coverage edge area is analyzed, which improves the accuracy of the signal analysis method of the 4G network indoor distribution system.

[0161] Figure 6This is a schematic flowchart illustrating the signal analysis of the indoor distribution system of the building to be analyzed based on the building homogeneity rate of the second indoor distribution system, as provided in the fourth embodiment of this application. Figure 4 Based on the previous embodiment, this embodiment describes in detail the process of performing signal analysis on the indoor distribution system of the building to be analyzed according to the building homogeneity rate of the second indoor distribution system.

[0162] like Figure 6 As shown, the signal analysis of the indoor distribution system of the building to be analyzed based on the building homogeneity rate of the second indoor distribution system in this embodiment may include the following steps:

[0163] Step S601: When the building homogeneity rate of the second indoor distribution system is higher than the building homogeneity rate threshold, the quality of the first indoor distribution system and the second indoor distribution system of the building to be analyzed is equivalent.

[0164] As described in step S402, when performing signal analysis on the indoor distribution system of the building to be analyzed based on the completion status of the building two-way signal analysis, when the completion status of the building two-way signal analysis is "the building two-way signal analysis has been completed", the building homogeneity rate of the second indoor distribution system is obtained, and the signal analysis of the indoor distribution system of the building to be analyzed is performed based on the building homogeneity rate of the second indoor distribution system.

[0165] Specifically, as described in step S401 regarding the building homogeneity threshold, when the building homogeneity of the second indoor distribution system is higher than the building homogeneity threshold, the quality of the first and second indoor distribution systems of the building to be analyzed is equivalent.

[0166] Step S602: When the building homogeneity rate of the second indoor distribution system is lower than the building homogeneity rate threshold, the signal quality of the second indoor distribution system of the building to be analyzed is better.

[0167] Specifically, as described in step S401 regarding the building homogeneity threshold, when the building homogeneity of the second indoor distribution system is lower than the building homogeneity threshold, the signal quality of the second indoor distribution system of the building to be analyzed is better.

[0168] This embodiment provides a process for signal analysis of the indoor distribution system of the building to be analyzed based on the building homogeneity rate of the second indoor distribution system. By adding the analysis of the building homogeneity rate of the second indoor distribution system on the basis of the analysis of the building homogeneity rate of the first indoor distribution system, the accuracy of the signal analysis method of the 4G network indoor distribution system is improved.

[0169] Figure 7 This is a flowchart illustrating the signal analysis process of the indoor distribution system of the cell to be analyzed based on the completion status of the bidirectional signal analysis, as provided in the fifth embodiment of this application. Figure 4Based on the implementation example, the completion status of cell two-way signal analysis includes: cell two-way signal analysis completed and cell two-way signal analysis not completed. This implementation example describes in detail the process of performing signal analysis on the indoor distribution system of the cell to be analyzed according to the completion status of cell two-way signal analysis.

[0170] like Figure 7 As shown, the signal analysis of the indoor distribution system of the cell to be analyzed based on the completion status of the bidirectional signal analysis in this embodiment may include the following steps:

[0171] Step S701: When the cell bidirectional signal analysis completion status is "cell bidirectional signal analysis not completed", send an inter-frequency signal measurement command to the second indoor distribution system, and perform signal analysis on the indoor distribution system of the cell to be analyzed based on the response of the second indoor distribution system to the inter-frequency signal measurement command.

[0172] Specifically, as described in step S403, when the cell homogeneity rate of the first indoor distribution system is higher than the cell homogeneity rate threshold, as described above, within the range of the indoor distribution cell and within the range of the cell initiating the measurement, the signal quality of the first indoor distribution system and the second indoor distribution system is comparable. In this case, it is necessary to perform signal analysis on the indoor distribution system of the cell to be analyzed based on the completion status of the bidirectional cell signal analysis, that is, to analyze the signal quality of each indoor distribution system in the area to be analyzed from the perspective of the second indoor distribution system. The bidirectional cell signal analysis is the process by which each indoor distribution system in the area to be tested receives the inter-frequency signal measurement command sent by the signal analysis device of the 4G network indoor distribution system of this application and obtains the cell homogeneity rate. The cell homogeneity rate of the second indoor distribution system can be calculated using the cell-level indoor distribution system signal analysis model proposed in this application, or it can be calculated using the operator's own cell homogeneity rate calculation method for the second indoor distribution system.

[0173] The completion status of two-way signal analysis for cells includes: cells that have completed two-way signal analysis and cells that have not completed two-way signal analysis.

[0174] Specifically, when the completion status of the two-way signal analysis of the cell is "incomplete", a cross-frequency signal measurement command is sent to the second indoor distribution system. Based on the response of the second indoor distribution system to the cross-frequency signal measurement command, the signal analysis of the indoor distribution system of the cell to be analyzed is performed.

[0175] In this application, when the second indoor distribution system receives an inter-frequency signal measurement command sent by the signal analysis device of the 4G network indoor distribution system, two scenarios may occur: the second indoor distribution system responds to the command, i.e., it initiates an inter-frequency measurement; or it does not respond to the command, i.e., it does not initiate an inter-frequency measurement. Specifically, signal analysis can be performed on the indoor distribution system of the cell to be analyzed based on the response of the second indoor distribution system to the inter-frequency signal measurement command described above.

[0176] Specifically, when the second indoor distribution system responds to the inter-frequency signal measurement command, the cell homogeneity rate of the second indoor distribution system is collected.

[0177] Optionally, the cell homogeneity rate of the second indoor distribution system can be calculated using the cell-level indoor distribution system signal analysis model proposed in this application, or it can be calculated using the cell homogeneity rate calculation method owned by the operator of the second indoor distribution system.

[0178] Specifically, when the second indoor distribution system does not respond to the measurement command for the inter-frequency signal, the signal analysis of the indoor distribution system of the cell to be analyzed is performed according to the signal analysis model of the indoor distribution system in the coverage edge area.

[0179] When the second indoor distribution system does not respond to the inter-frequency signal measurement command, the second indoor distribution system does not initiate inter-frequency measurement. At this time, the signal analysis of the indoor distribution system of the building to be analyzed can be performed according to the signal analysis model of the indoor distribution system in the coverage edge area described in step S502.

[0180] The expression for the excellent coverage rate of a residential area is as follows:

[0181]

[0182] The sum of user measurements initiated by users whose signal strength in measurement cell S1 is below the edge threshold refers to the total frequency of inter-frequency measurements initiated by all user terminals within the edge coverage area of ​​the first indoor distribution system in the building under analysis during the measurement period. Whether a user terminal initiating measurement cell S1 is within the edge coverage area is determined by the signal strength of the initiating measurement cell. When a user terminal initiates an inter-frequency measurement, if the signal strength MR.LteScRSRP of the initiating measurement cell is below the edge threshold, the user terminal is considered to be within the edge coverage area of ​​the initiating measurement cell S1.

[0183] The sum of the number of times the signal strength of the adjacent cells to be measured is the sum of the number of times the signal strength MR.LteScRSRP of the initiating measurement cell is better than that of all user terminals under the coverage edge of the initiating measurement cell S1 of the first indoor distribution system in the building to be analyzed during all inter-frequency measurements. The number of times the signal strength MR.LteScRSRP of the initiating measurement cell is better refers to the number of times, during an inter-frequency measurement, the signal strength MR.LteScRSRP of a user terminal under the coverage edge of the initiating measurement cell S1 of the first indoor distribution system in the building to be analyzed is higher than that of the initiating measurement cell by a certain range, for example, 3dB. The difference between the signal strength MR.LteScRSRP of the initiating measurement cell and the signal strength MR.LteScRSRP of the initiating measurement cell can be set according to actual needs.

[0184] Among them, the excellent coverage rate of the cell, that is, the excellent coverage rate of the distribution system in the coverage edge area of ​​the cell is less than 1. The closer the excellent coverage rate of the indoor distribution system is to 1, the better the coverage of the indoor distribution system of the adjacent cells to be measured in the coverage edge area of ​​the cell.

[0185] Specifically, a cell coverage excellence threshold can be set to determine the signal quality of each indoor distributed antenna system (DAS) at the coverage edge area. When the cell coverage excellence rate of an indoor DAS is higher than the threshold, the signal quality of the DAS corresponding to the adjacent cell being measured is better than that of the DAS corresponding to the cell initiating the measurement. When the cell coverage excellence rate of an indoor DAS is lower than the threshold, the signal quality of the DAS corresponding to the adjacent cell being measured is comparable to that of the DAS corresponding to the cell initiating the measurement. The cell coverage excellence threshold can be set according to the operator's requirements for indoor DAS signal quality.

[0186] Step S702: When the cell bidirectional signal analysis is completed, obtain the cell homogeneity rate of the second indoor distribution system, and perform signal analysis on the indoor distribution system of the cell to be analyzed based on the cell homogeneity rate of the second indoor distribution system.

[0187] Specifically, when the cell bidirectional signal analysis is completed, the cell homogeneity rate of the second indoor distribution system can be obtained. This rate can be calculated using the cell-level indoor distribution system signal analysis model proposed in this application, or using the operator's proprietary cell homogeneity rate calculation method. Then, signal analysis is performed on the indoor distribution system of the cell to be analyzed based on the cell homogeneity rate of the second indoor distribution system.

[0188] Specifically, when the cell homogeneity rate of the second indoor distribution system is higher than the cell homogeneity rate threshold, the quality of the first indoor distribution system and the second indoor distribution system of the cell to be analyzed is equivalent.

[0189] Specifically, when the cell homogeneity rate of the second indoor distribution system is lower than the cell homogeneity rate threshold, the signal quality of the second indoor distribution system of the cell to be analyzed is better.

[0190] This embodiment describes the process of performing signal analysis on the indoor distribution system of the cell to be analyzed based on the completion status of the cell bidirectional signal analysis.

Specifically, the inter-frequency signal measurement data of the first indoor distribution system obtained in step S104 can be input into the signal analysis model of the indoor distribution system in the coverage edge area to obtain the excellent coverage rate of the first indoor distribution system described in step S701.

[0195] Step S802: When the cell coverage rate of the first indoor distribution system is higher than the cell coverage rate threshold, the signal quality of the second indoor distribution system in the cell to be analyzed is better.

[0196] Specifically, when the cell coverage rate of the first indoor distribution system obtained in step S801 is higher than the cell coverage rate threshold described in step S701, the signal quality of the second indoor distribution system of the cell to be analyzed is better.

[0197] Step S803: When the cell coverage rate of the first indoor distribution system is lower than the cell coverage rate threshold, the quality of the first indoor distribution system and the second indoor distribution system in the cell to be analyzed is equivalent.

[0198] Specifically, when the cell coverage rate of the first indoor distribution system obtained in step S801 is lower than the cell coverage rate threshold described in step S701, the quality of the first indoor distribution system and the second indoor distribution system of the cell to be analyzed is equivalent.
