Description

Technical Field

[0001] This application relates to the field of mobile communication technology, specifically to a method and apparatus for determining 5G indoor distribution system construction. Background Technology

[0002] Currently, the goal of each operator is to maximize network coverage to outpace competitors while minimizing investment. Since 80% of mobile users are located indoors, indoor coverage is the key to network coverage and quality competition. Therefore, accurately assessing the construction status of indoor coverage competitors is crucial for precise planning, precise construction, and effective marketing.

[0003] 4G network coverage assessment can be analyzed using MDT data, and indoor distribution system construction can also be assessed using MDT data. However, due to the limited progress of the 5G MDT protocol, there is currently no 5G MDT data available, making it impossible to determine indoor distribution system construction using 5G MDT. Summary of the Invention

[0007] The distance and name similarity between the 4G indoor distributed base station and the first 5G indoor distributed base station are determined based on the feature information and engineering parameter data, and the construction status of the first 5G indoor distributed base station of the 4G indoor distributed base station is determined based on the distance and / or the name similarity.

[0008] If the 4G indoor distributed base station is equipped with the first 5G indoor distributed base station, then based on the first level information in the MR data collected by the inter-frequency measurement of the first 5G indoor distributed base station and the second level information of the competitor, the construction status of the competitor's second 5G indoor distributed base station at the 4G indoor distributed base station is determined.

[0009] If the 4G indoor distributed base station does not have the first 5G indoor distributed base station, then the construction status of the competitor's second 5G indoor distributed base station at the 4G indoor distributed base station is determined based on the third level information and static call detail record information of the competitor in the MR data collected by the inter-system measurement of the 4G indoor distributed base station.

[0011] If the feature information includes multiple 5G base station accounts and / or multiple 5G physical cell identifiers, then the latitude and longitude information and station name of the 4G indoor distribution site and the first 5G indoor distribution site are determined according to the engineering parameter data.

[0012] The distance between the 4G indoor distribution site and the first 5G indoor distribution site is determined based on the latitude and longitude information;

[0013] The similarity between the names of the 4G indoor distributed antenna system (DAS) site and the first 5G indoor distributed antenna system (DAS) site is determined based on a similarity algorithm and the site name.

[0014] In one embodiment, determining the construction status of the first 5G indoor distributed base station of the 4G indoor distributed base station based on the distance and / or the station name similarity includes:

[0015] When the distance is within the set range, it is determined that the 4G indoor distribution site is equipped with the first 5G indoor distribution site;

[0016] When the distance is not within the set range and the similarity is greater than the set value, it is determined that the 4G indoor distribution site is equipped with the first 5G indoor distribution site.

[0017] In one embodiment, the step of determining the competitor's construction status of the second 5G indoor distributed base station at the 4G indoor distributed base station based on the first level information in the MR data collected by inter-frequency measurement at the first 5G indoor distributed base station and the competitor's second level information includes:

[0018] Based on the MR data collected by the inter-frequency measurement of the first 5G indoor distribution site, the first average level and the first maximum level of the 5G network in the coverage area corresponding to each first physical cell identifier are determined, as well as the second average level and the second maximum level of the 5G network in the coverage area corresponding to each second physical cell identifier.

[0020] In one embodiment, determining the competitor's construction status of a second 5G indoor distributed antenna system (DSAS) at the 4G indoor distributed antenna system (DSAS) site based on the first level information in the MR data collected by inter-frequency measurement at the first 5G indoor distributed antenna system (DSAS) site and the competitor's second level information includes:

[0021] Determine a first difference between the first average level and the second average level, and a second difference between the first maximum level and the second maximum level;

[0022] When the second average level is greater than the first set level, the second maximum level is greater than the second set level, and both the first difference and the second difference are less than the set difference, it is determined that the competitor has a second 5G indoor distribution site at the 4G indoor distribution site.

[0023] In one embodiment, determining the competitor's status regarding the construction of a second 5G indoor distributed antenna system (DSS) at the 4G DAS site based on the competitor's third-level information and static call detail records (CDRs) from the MR data collected by inter-system measurements at the 4G DAS site includes:

[0024] Based on the MR data collected by the inter-system measurement of 4G indoor distributed antenna system sites, the third average level and the third maximum level of the 5G network in the coverage area corresponding to each third physical cell identifier are determined, wherein the third level information includes the third average level and the third maximum level;

[0025] The number of static call detail records (CDRs) and the number of long call detail records (LTRs) are determined based on the MR data collected by the 4G indoor distributed antenna system (DAS) measurement system. The proportion of static CDRs is then determined based on the number of static CDRs and the number of LRTs. The static CDR information includes the number of static CDRs and the number of LRTs.

[0026] In one embodiment, determining the competitor's construction status of a second 5G indoor distributed antenna system (DSS) at the 4G DAS site based on the competitor's third-level information and static call detail records (CDRs) from the MR data collected by inter-system measurements at the 4G DAS site includes:

[0027] When the third average level is greater than the third set level, the third maximum level is greater than the fourth set level, and the static call detail record percentage is greater than the set percentage, it is determined that the competitor has a second 5G indoor distribution site at the 4G indoor distribution site.

[0028] Secondly, embodiments of this application provide a 5G indoor distribution system construction discrimination device, comprising:

[0029] The first determining module is used to determine the characteristic information of the 5G cell based on the measurement report MR data collected by the inter-system measurement of the 4G indoor distribution site. The characteristic information includes the 5G base station number and / or the 5G physical cell identifier.

[0030] The second determining module is used to determine the distance and name similarity between the 4G indoor distribution site and the first 5G indoor distribution site based on the feature information and engineering parameter data, and to determine the construction status of the first 5G indoor distribution site of the 4G indoor distribution site based on the distance and / or the name similarity.

[0031] The first judgment module is used to determine the construction status of the competitor's second 5G indoor distribution site at the 4G indoor distribution site if the 4G indoor distribution site is equipped with the first 5G indoor distribution site, based on the first level information in the MR data collected by the inter-frequency measurement of the first 5G indoor distribution site and the second level information of the competitor.

[0032] The second judgment module is used to determine the construction status of the competitor's second 5G indoor distribution site at the 4G indoor distribution site if the first 5G indoor distribution site is not located at the 4G indoor distribution site, based on the competitor's third level information and static call detail record information in the MR data collected by the inter-system measurement of the 4G indoor distribution site.

[0033] Thirdly, embodiments of this application provide an electronic device, including a processor and a memory storing a computer program, wherein the processor executes the program to implement the steps of the 5G indoor distribution construction discrimination method described in the first aspect.

[0034] Fourthly, embodiments of this application provide a computer program product, including a computer program, which, when executed by a processor, implements the steps of the 5G indoor distribution construction discrimination method described in the first aspect.

[0035] The 5G indoor distributed antenna system (DAS) construction discrimination method and apparatus provided in this application embodiment determine the characteristic information of the 5G cell based on the measurement report (MR) data collected from the inter-system measurement of the 4G indoor DAS site.

Based on the characteristic information and engineering parameter data, the distance and station name similarity between the 4G indoor DAS site and the first 5G indoor DAS site are determined, and the construction status of the first 5G indoor DAS site of the 4G indoor DAS site is determined based on the distance and / or station name similarity. If the 4G indoor DAS site has the first 5G indoor DAS site, the construction status of the competitor's second 5G indoor DAS site at the 4G indoor DAS site is determined based on the first level information in the MR data collected from the inter-frequency measurement of the first 5G indoor DAS site and the second level information of the competitor. If the 4G indoor DAS site does not have the first 5G indoor DAS site, the construction status of the competitor's second 5G indoor DAS site at the 4G indoor DAS site is determined based on the third level information of the competitor and static call detail records in the MR data collected from the inter-system measurement of the 4G indoor DAS site. This application embodiment uses MR data collected by the corresponding base station to perform algorithmic discrimination to determine the construction status of 5G indoor distributed base stations within 4G indoor distributed base stations.

[0045] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions of this application will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0046] Figure 1 This is one of the flowcharts illustrating the 5G indoor distribution system construction determination method provided in this application embodiment. (Refer to...) Figure 1 This application provides a method for determining the construction of 5G indoor distribution systems, which may include:

[0047] Step S10: Determine the characteristic information of the 5G cell based on the measurement report MR data collected by the 4G indoor distributed system site inter-system measurement. The characteristic information includes the 5G base station number and / or the 5G physical cell identifier.

[0048] It should be noted that current mainstream manufacturers' 4G base stations have the capability to issue 5G inter-system measurement commands. For example, they can initiate measurement and control tasks on frequencies such as 504990 for China Mobile, and 627264, 633984 (3.5G), and 422890 (2.1G) for China Telecom and China Unicom. Meanwhile, mainstream 5G commercial terminals also support reporting 5G inter-system measurements when occupying 4G base stations. The MR (Measurement Report) data for 4G inter-system measurements includes various fields, such as MR type, call detail record ID, 4G cell number, collection date, measured 5G base station ID, measured 5G cell number, 5G cell PCI (Physical Cell Identifier), and 4G cell RSRQ (Reference Signal Receiving Quality). These fields can be used to assess the 5G coverage of the local network and competitors. Meanwhile, mainstream manufacturers' 5G base stations currently have the capability to issue 5G inter-frequency measurements, that is, to initiate measurement and control tasks for other 5G frequencies besides the occupied frequency. Mainstream 5G commercial terminals also support reporting 5G inter-frequency measurements. Among them, the MR data of 5G inter-frequency measurements includes a variety of fields, such as 5G base station ID, 5G cell PCI, 5G cell RSRQ, 5G cell RSRP (Reference Signal Receiving Power), inter-frequency cell ID, etc. These fields can be used to evaluate the 5G coverage of the network itself and competitors.

[0049] This application embodiment collects MR data through 4G indoor distributed system site measurement, and then parses the MR data to obtain the characteristic information of the operator's own 5G cell. The characteristic information includes the 5G base station number (i.e., 5G base station ID or gNodeB ID) and / or 5G physical cell identifier (i.e. 5G PCI).

[0050] Step S20: Determine the distance and name similarity between the 4G indoor distribution site and the first 5G indoor distribution site based on the feature information and engineering parameter data, and determine the construction status of the first 5G indoor distribution site of the 4G indoor distribution site based on the distance and / or the name similarity.

[0051] It should be noted that, in the embodiments of this application, the first 5G indoor distributed site refers to the 5G indoor distributed site built by this operator, and the second 5G indoor distributed site refers to the 5G indoor distributed site built by competitors. For example, assuming that this operator is China Mobile, then the 5G indoor distributed site built by China Mobile is the first 5G indoor distributed site, while the 5G indoor distributed site built by China Telecom or China Unicom is the second 5G indoor distributed site.

[0052] The number of 5G base station numbers and 5G physical cell identifiers is determined based on feature information. If multiple 5G base station numbers and / or multiple 5G physical cell identifiers are parsed from MR data, it cannot be determined whether the current 4G indoor site has a first 5G indoor distributed antenna system (DAS) site, since multiple 5G base station numbers or multiple 5G physical cell identifiers may correspond to a single 5G cell. Therefore, it is not possible to determine whether the 4G indoor DAS site has a first 5G indoor DAS site. In this case, it is necessary to further determine whether the 4G indoor DAS site has a first 5G indoor DAS site based on a combination of distance and similarity judgments. Specifically, 4G and 5G engineering parameter data are collected. Then, based on the 4G engineering parameter data, the latitude and longitude information and site name of the 4G indoor DAS site are determined. Based on the 5G engineering parameter data, the latitude and longitude information and site name of the first 5G indoor DAS site are determined. Then, the distance between the 4G indoor DAS site and the identified first 5G indoor DAS site is calculated using a latitude and longitude distance function. The formula for calculating the latitude and longitude distance function is as follows:

[0053] D=R arccos[cos(Y1) cos(Y2) cos(X1-X2)+sin(Y1) sin(Y2)];

[0054] Where D is the distance between the 4G indoor distributed base station and the first 5G indoor distributed base station; R is the Earth's radius; the latitude and longitude of the 4G indoor distributed base station are (X1, Y1), and the latitude and longitude of the first 5G indoor distributed base station are (X2, Y2), where X1 and X2 are longitudes, and Y1 and Y2 are latitudes.

[0055] Then, a similarity algorithm is used to calculate the similarity between the 4G station name and the first identified 5G station name. The similarity algorithm is as follows:

[0056] S=LEN({Same}) / MAX(LEN(Name1),LEN(Name2));

[0057] Where S is the station name similarity; Name1: station name 1, such as {ABCDEFG}; Name2: station name 1, such as {ABDFGH}; Same: same characters, such as {ABDFG}; LEN() function, used to return the number of characters in a text string.

[0058] In this application embodiment, latitude and longitude distance functions and similarity algorithms are used to calculate the distance between the 4G indoor distributed base station and the identified first 5G indoor distributed base station, as well as the similarity of the station name, which improves the accuracy of distance and similarity calculation.

[0059] It should be noted that, due to the potential inaccuracies in the site latitude and longitude information in the operator's engineering parameters data, and to avoid misjudging whether a 4G indoor distributed antenna system (DAS) site has a corresponding first 5G indoor distributed antenna system (BAS) site due to 5G signal leakage from other nearby BAS sites, a combination of distance judgment and similarity judgment is adopted to determine whether a 4G indoor distributed antenna system site has a corresponding first 5G indoor distributed antenna system (BAS) site.

[0060] Specifically, it is determined whether the distance between the 4G indoor distributed base station and the first 5G indoor distributed base station is within a set range (e.g., 50M), that is, whether the first 5G indoor distributed base station is within the set range of the 4G indoor distributed base station. If it is within the set range, it is determined that the 4G indoor distributed base station has the first 5G indoor distributed base station. If it is not within the set range, it is necessary to determine the similarity of the base station names.

[0061] For a first 5G indoor distributed antenna system (DAS) site that is not within the designated range of a 4G indoor distributed antenna system (DAS) site, the similarity between the site name of the first 5G indoor DAS site and the 4G indoor DAS site is matched to determine whether the first 5G indoor DAS site exists. Specifically, it is determined whether the similarity is greater than a set value (e.g., 80%). If the similarity is greater than the set value, it is determined that the 4G indoor DAS site has a first 5G indoor DAS site; if the similarity is less than the set value, it is determined that the 4G indoor DAS site does not have a first 5G indoor DAS site.

[0062] This application embodiment uses a combination of distance judgment and similarity judgment to determine the construction status of the first 5G indoor distribution site, avoiding misjudgment of whether the first 5G indoor distribution site exists due to 5G signal leakage from other indoor distribution sites that are relatively close, thus improving the accuracy of the judgment results.

[0063] Step S30: If the 4G indoor distribution site is equipped with the first 5G indoor distribution site, then based on the first level information in the MR data collected by the inter-frequency measurement of the first 5G indoor distribution site and the second level information of the competitor, determine the construction status of the competitor's second 5G indoor distribution site at the 4G indoor distribution site.

[0064] After confirming that a first 5G indoor distributed antenna system (DAS) site is located at the 4G indoor DAS site, it is necessary to further determine whether competitors have established a second 5G indoor DAS site at the same 4G indoor DAS site. Specifically, if a first 5G indoor DAS site is located at the 4G indoor DAS site, the first voltage level information of the 5G indoor DAS site and the second voltage level information of the competitors are determined based on the MR data collected by inter-frequency measurement at the first 5G indoor DAS site. Then, based on the first voltage level information and the second voltage level information, the construction status of the competitors' second 5G indoor DAS site at the 4G indoor DAS site is determined.

[0065] Step S40: If the 4G indoor distributed base station does not have the first 5G indoor distributed base station, then based on the third level information and static call detail record information of the competitor in the MR data collected by the inter-system measurement of the 4G indoor distributed base station, determine the construction status of the competitor's second 5G indoor distributed base station at the 4G indoor distributed base station.

[0066] If the 4G indoor distributed antenna system (DAS) site does not have a first 5G indoor distributed antenna system (DAS) site, the competitor's third-level information and static call detail records (CDRs) are determined based on the MR data collected from the 4G indoor distributed antenna system inter-system measurement. Then, based on the third-level information and static CDRs, the construction status of the competitor's second 5G indoor distributed antenna system (DAS) site at the 4G indoor distributed antenna system site is determined.

[0067] The 5G indoor distributed antenna system (DAS) construction discrimination method provided in this application combines 4G indoor DAS site data with 4G & 5G MR data to mine inter-system 5G MR data collected by the operator's 4G indoor DAS site. It uses the collected gNodeB ID and PCI combined with distance and site name similarity to determine whether the indoor DAS site has a co-coverage first 5G indoor DAS site of the operator. If there is a co-coverage first 5G indoor DAS site, it uses the RSRP of competitor inter-frequency MR data collected by the first 5G indoor DAS site to determine whether other operators are building second 5G indoor DAS sites. When there is no 5G coverage by the operator, 4G inter-system MR data is used to discriminate the construction of second 5G indoor DAS sites by other operators. The concept of static call detail records (CDRs) is introduced to distinguish indoor site signals from outdoor macrocell site signals. Based on this, the MR data collected by the corresponding base station is used for algorithm discrimination to determine the construction status of 5G indoor DAS sites within 4G indoor DAS sites. This avoids indoor MR positioning errors caused by latitude and longitude errors in MDT data, improving the accuracy of the discrimination results.

[0068] refer to Figure 2 , Figure 2 This is a second flowchart illustrating the method for determining 5G indoor distributed antenna system (DAS) construction provided in this application embodiment. In this application embodiment, determining the construction status of the competitor's second 5G indoor distributed antenna system (DSIS) site at the 4G DAS site based on the first level information in the MR data collected by inter-frequency measurement at the first 5G DAS site and the competitor's second level information includes:

[0069] Step S31: Determine the first difference between the first average level and the second average level, and the second difference between the first maximum level and the second maximum level;

[0070] Step S32: When the second average level is greater than the first set level, the second maximum level is greater than the second set level, and both the first difference and the second difference are less than the set difference, it is determined that the competitor has a second 5G indoor distribution site at the 4G indoor distribution site.

[0071] It should be noted that if a first 5G indoor distributed antenna system (DAS) site has already been set up at the 4G indoor DAS site, the MR data collected by inter-frequency measurement at the first 5G indoor DAS site will be used to determine whether a competitor has built a second 5G indoor DAS site within the 4G indoor DAS site. Since large indoor coverage sites are split into multiple cells, each covering a different area and corresponding to a different PCI, the coverage assessment will be based on a precise PCI assessment.

[0072] Specifically, the local network reference signal received power (RSRP) in the inter-frequency MR data of the first 5G indoor distributed antenna system (DAS) site is summarized according to PCI, and the first average level of the 5G network in the coverage area corresponding to each first physical cell identifier (PCI) of the first 5G indoor DAS site is calculated. and the first maximum level Simultaneously, the RSRP of competitor frequency points is aggregated according to the competitor's second physical cell identifier (PCI), and the second average level of the 5G network in the coverage area corresponding to each competitor's PCI is calculated. Second maximum level The first level information includes the first average level. and the first maximum level The second level information includes the second average level. Second maximum level .

[0073] The formulas for calculating the average level and the maximum level are as follows:

[0074]

[0075]

[0076] Where N is the number of physical cells.

[0077] It is understood that in the embodiments of this application, "this network" refers to the network provided by the current operator. For example, assuming that the current operator is China Mobile, then the China Mobile network is the "this network", and competitors can be China Telecom and China Unicom.

[0078] Determine the first average level With the second average level The first difference, and the first maximum level With the second maximum level The second difference is when the PCI of the competitor corresponding to this network is aggregated. >AdBm、 >B dBm and both the first difference and the second difference are <C dB (if there are indoor distribution sites deployed in the same geographical environment, the levels should be close), it is determined that there is a competing second 5G indoor distribution site covering the indoor area corresponding to this PCI in this network; otherwise, it is determined that there is no competing second 5G indoor distribution site covering. Among them, the specific values of A, B, and C can be determined by each city according to the actual situation of indoor distribution. For example, referring to Figure 5 , Beijing Mobile determined A as -100 and B as -80 according to the CDF curve of the MR level of the 5G indoor distribution sites in Beijing, and determined C as 10 according to the experience of on-site testing.

[0079] The embodiment of this application uses the MR data collected by the corresponding base station to perform algorithm discrimination on the construction situation of the competing second 5G indoor distribution sites within the 4G indoor distribution sites, avoiding the indoor MR positioning deviation caused by the longitude and latitude errors in the MDT data, and improving the accuracy of the discrimination result.

[0080] Referring to Figure 3 , Figure 3 is the third flow schematic diagram of the discrimination method for 5G indoor distribution construction provided by the embodiment of this application. In the embodiment of this application, determining the construction situation of the second 5G indoor distribution site of the competitor at the 4G indoor distribution site according to the third level information and static call list information of the competitor in the MR data collected by the 4G indoor distribution site for inter-system measurement includes:

[0081] Step S41, when the third average level is greater than the third set level, the third maximum level is greater than the fourth set level, and the static call list ratio is greater than the set ratio, it is determined that the competitor has the second 5G indoor distribution site at the 4G indoor distribution site.

[0082] If there is only 4G coverage at the 4G indoor distribution site and there is no co-covered 5G indoor distribution site, the MR data of the inter-system competitor frequency points collected by this 4G indoor distribution site is used to determine whether the competitor has built a 5G indoor distribution site within the 4G indoor distribution site. Specifically, the overall judgment is divided into two steps:

[0083] Level judgment: Summarize the 4G inter-system competitor MR data according to the dimensions of the 4G local network PCI and the 5G competitor PCI. Specifically, summarize according to each third physical cell identifier (PCI) of the competitor, and calculate the third average level and the third maximum level If the third average MR level of a 5G competitor is greater than DdBm (e.g., >-100dBm), and the third maximum MR level of a 5G competitor is greater than EdBm (e.g., >-80dBm), then the PCI signal may be the competitor's second 5G indoor distribution site signal; otherwise, the PCI signal is not the competitor's indoor distribution site signal. The third level information includes the third average level. and the third maximum level .

[0084] To further verify whether the PCI signal belongs to a competitor's second 5G indoor distributed antenna system (DAS) site, static call detail records (CDRs) need to be performed. Specifically, when an indoor user receives coverage from an indoor DAS base station, the PCI remains unchanged and the RSRP remains relatively stable when stationary or moving within a short period. However, when an indoor user receives coverage from an outdoor macrocell base station, the RSRP fluctuates significantly due to the multipath propagation effect of macrocell signals, and the PCI changes, especially when the indoor user moves from near the outdoors to indoors, where the received signal shows significant fluctuations. Therefore, to further distinguish whether a PCI meeting the first step's level condition is an outdoor macrocell base station signal or an indoor microcell base station signal, the concept of static CDRs is introduced. A static CDR is defined as a call detail record where, within a single CDR (UlCallID in the 4G inter-system measurement table is the CDR ID), a competitor occupies the same PCI for more than 60 seconds and the standard deviation of the competitor's level fluctuation is less than a set value (e.g., <5).

[0085] Among them, the proportion of static call detail records is:

[0086] X=D / E 100%

[0087] Where D represents the number of static call detail records (CDRs), and E represents the number of long call detail records (CDRs). A CDR lasting longer than 60 seconds is counted as a long call detail record. If the percentage of static CDRs under this PCI is X > η, then the PCI signal is determined to be the signal of the second 5G indoor distribution site. Here, η can be determined based on the needs of different regions. For example, in the Beijing Mobile solution, η is taken as 60%.

[0088] In other words, if the MR of a competitor from another system collected by a 4G indoor distributed antenna system (DAS) site meets the thresholds for level and static call detail record (CDR) discrimination, it is determined that there is a competitor's second 5G indoor DAS site in that indoor area; otherwise, it is determined that there is no competitor's second 5G indoor DAS site.

[0089] In one embodiment, when there is no 5G indoor distributed antenna system (DAS) site available indoors, the steps to determine whether a competitor has a second 5G indoor DAS site are as follows:

[0090] Step a, 5G indoor distribution network construction status determination: Confirm through 4G MR data and engineering parameter data that no 5G indoor distribution network has been built at the 4G indoor distribution site.

[0091] Step b, Determining the 5G indoor distributed antenna system (DAS) level of competitors: Extract the 5G MR data of competitors collected from the mobile 4G site. Based on the judgment conditions that the average 5G level is >-100dBm and the maximum level is >-80dBm, it is preliminarily determined that the PCI that meets the above conditions may be an indoor distributed antenna system (DAS) cell. For example, refer to Table 1, which is a summary of the MR levels of competitors in different 4G systems.

[0092] Table 1

[0093] frequency PCI Average level Number of sampling points maximum level Preliminary judgment 627264 981 -92.0 350 -72 Possibly a room-by-room distribution system 627264 976 -93.3 1409 -60 Possibly a room-by-room distribution system 627264 985 -93.8 118 -78 Possibly a room-by-room distribution system 627264 994 -95.0 300 -71 Possibly a room-by-room distribution system 627264 986 -96.5 728 -69 Possibly a room distribution system 627264 982 -99.0 395 -66 Possibly a room distribution system 627264 988 -99.7 461 -72 Possibly a room distribution system 633984 226 -110.0 346 -95 Non-ventilated 633984 502 -115.5 1234 -94 Non-ventilated 633984 117 -121.3 152 -106 Non-ventilated

[0094] Step c, confirm the static call detail record ratio:

[0095] 1. By confirming that the strongest NR PCI has not changed within 60 seconds, assume there are 17 call detail records (CDRs).

[0096] 2. The standard deviation of RSRP value fluctuation is less than 5 call records, assuming there are 15 call records.

[0097] 3. The percentage of static call detail records is confirmed: 15 / 20 = 75%.

[0098] This application embodiment uses MR data collected by the corresponding base station to perform an algorithm to determine the construction status of a competitor's second 5G indoor distributed site within the 4G indoor distributed site, avoiding indoor MR positioning deviations caused by latitude and longitude errors in MDT data, and improving the accuracy of the determination results.

[0099] refer to Figure 4 , Figure 4 This is the fourth flowchart of the method for determining 5G indoor distribution system construction provided in the embodiments of this application.

[0100] This application embodiment uses 4G and 5G MR data from indoor 4G distributed antenna system (DAS) sites to determine the 5G indoor site construction status of each operator, forming a four-quadrant assessment of competitors' 5G construction in indoor scenarios, as shown in the reference. Figure 6 It is used to provide marketing and guide the precise advancement of indoor site construction.

[0101] The overall judgment method is as follows: Combine 4G and 5G MR data of 4G indoor distributed antenna system (DAS) sites, mine the inter-system 5G MR data collected by the operator's 4G indoor DAS sites, and determine whether the indoor DAS site has the same coverage as the operator's first 5G indoor DAS site by combining the collected gNodeBID and PCI distance and site name similarity. If there is a same coverage as the operator's first 5G indoor DAS site, determine whether other operators have second 5G indoor DAS sites by using the RSRP of the competitor's inter-frequency MR data collected by the 5G indoor DAS site. When there is no 5G coverage by the operator, use 4G inter-system MR data to judge the construction of other operators' second 5G indoor DAS sites, and introduce the concept of static call detail records (CDRs) to distinguish between indoor site signals and outdoor macrocell site signals.

[0102] For example, mobile 5G MR data is collected through mobile 4G sites. Based on 4G inter-system measurements, the base station ID, cell ID, cell frequency, and cell PCI of the 5G cell are analyzed to match 5G indoor distributed antenna system (DAS) cells within a 50MHz radius. If a match is successful, the comprehensive data table is consulted to determine if the mobile 4G and mobile 5G cells have the same coverage. If no match is found, the following checks are performed: 1. If the 5G cell's base station ID is obtained, the similarity between the 4G and 5G site names is used to determine if a first 5G indoor DAS site exists (e.g., similarity of 80%). 2. If the 5G cell's base station ID is not obtained, indoor DAS sites across the entire network are matched based on the 5G frequency and PCI; the site with the highest similarity between the 4G and 5G site names is matched to determine if a first 5G indoor DAS site exists (e.g., similarity of 80%).

[0103] If a 4G indoor distributed antenna system (DAS) site is covered by both China Mobile's 4G and 5G cells, the next step is to determine whether a competitor has built a second 5G DAS site at that indoor location. Specifically, 5G MR data from the competitor is collected through the China Mobile 5G DAS site, with the signal strength measured at frequency 633984 / 627264. If the difference between the competitor's average 5G MR signal strength (or maximum signal strength) and the average 5G MR signal strength (or maximum signal strength) of the China Mobile 5G DAS site is less than 10 dB, and the competitor's average 5G MR signal strength is greater than -100 dBm, and the competitor's maximum 5G MR signal strength is greater than -80 dBm, then it indicates that the competitor has a second 5G DAS site at the current indoor location. If the above conditions are not met, then the second 5G DAS site is determined to be an outdoor site.

[0104] If the 4G indoor distributed antenna system (DAS) site does not have simultaneous coverage by both China Mobile's 4G and 5G cells, further investigation is needed to determine if a competitor has built a second 5G DAS site at that location. Specifically, 5G MR data from the competitor is collected through the China Mobile 4G site, with the contact frequency being 633984 / 627264 and PCI being A. If the average 5G MR level is greater than -100dBm and the maximum level is greater than -80dBm, it indicates that the PCI signal may be from a competitor's 5G indoor DAS site. Further investigation is needed to determine if the proportion of static call records (CDRs) with a duration greater than 60 seconds under that 5G cell is greater than 60%. If so, it indicates that a competitor has a 5G DAS site at the current indoor location. If the above conditions are not met, the second 5G DAS site is determined to be an outdoor site. The criteria for determining static CDRs are: 1. The frequency and PCI remain unchanged within the CDR; 2. The standard deviation of the 5G MR RSRP value fluctuation within the CDR is less than 5.

[0105] Based on the above judgment results, it can be identified whether a certain indoor distribution scenario has the operator's first 5G indoor distribution site and a competitor's second 5G indoor distribution site, resulting in a four-quadrant profile of 5G indoor distribution site competitor coverage: China Mobile has it, competitor does not; China Mobile has it, competitor has it; China Mobile does not have it, competitor does not; China Mobile does not have it, competitor has it.

[0106] For scenarios where both mobile and competitors have their own: routine network quality monitoring and key scenario testing;

[0107] For scenarios where mobile devices are unavailable but competitors have them: guide construction and follow up, and promote indoor construction based on a comprehensive consideration of scenario value, user value, etc.

[0108] For scenarios where mobile users have an advantage but competitors don't: leverage absolute advantage, deploy the marketing department to increase marketing efforts, encourage 4G users to migrate, and encourage competitors' 4 / 5G users to switch.

[0109] For scenarios where there is no mobile coverage and no competitors: periodically monitor and assess changes in competitor coverage.

[0110] The embodiments of this application, which determine the 5G deployment status of indoor distribution sites based on 4G & 5G MR information, have the following advantages:

[0111] 1. The algorithm uses MR data collected from the corresponding base station for discrimination, avoiding indoor MR positioning deviations caused by latitude and longitude errors in MR positioning or MDT data, making the discrimination results more accurate.

[0112] 2. Using MR data to determine the status of indoor distribution system construction is more efficient and convenient than on-site testing, and is easier to promote across the entire network.

[0113] The following describes the 5G indoor distributed antenna system (DAS) construction discrimination device provided in the embodiments of this application. The 5G indoor distributed antenna system (DAS) construction discrimination device described below can be referred to in correspondence with the 5G indoor distributed antenna system (DAS) construction discrimination method described above.

[0117] The first judgment module 703 is used to determine the construction status of the competitor's second 5G indoor distribution site at the 4G indoor distribution site based on the first level information in the MR data collected by the inter-frequency measurement of the first 5G indoor distribution site and the second level information of the competitor, if the 4G indoor distribution site is equipped with the first 5G indoor distribution site.

[0118] The second judgment module 704 is used to determine the construction status of the competitor's second 5G indoor distribution site at the 4G indoor distribution site if the first 5G indoor distribution site is not located at the 4G indoor distribution site, based on the competitor's third level information and static call detail record information in the MR data collected by the inter-system measurement of the 4G indoor distribution site.

[0119] The 5G indoor distributed antenna system (DAS) construction discrimination device provided in this application embodiment determines the characteristic information of the 5G cell based on the measurement report (MR) data collected from the inter-system measurement of the 4G indoor DAS site.

If the 4G indoor DAS site has the first 5G indoor DAS site, it determines the construction status of the competitor's second 5G indoor DAS site at the 4G indoor DAS site based on the first level information in the MR data collected from the inter-frequency measurement of the first 5G indoor DAS site and the competitor's second level information. If the 4G indoor DAS site does not have the first 5G indoor DAS site, it determines the construction status of the competitor's second 5G indoor DAS site at the 4G indoor DAS site based on the competitor's third level information and static call detail records in the MR data collected from the inter-system measurement of the 4G indoor DAS site. This application embodiment uses MR data collected by the corresponding base station to perform algorithmic discrimination to determine the construction status of 5G indoor distributed base stations within 4G indoor distributed base stations.
