Description

Technical Field

[0001] The present application relates to the field of mobile communication wireless technology, and in particular to a multi-channel power imbalance positioning method, device, equipment and storage medium. Background Art

[0002] The biggest advantage of 5G network over 2 / 3 / 4G network is that it provides a higher experience rate, and high rate is also an important guarantee for users to smoothly experience various Internet services. Therefore, the level of experience rate directly affects the user's stickiness and the reputation of the operator. The construction method of the traditional DAS (Direct-Attached Storage, open system direct-attached storage) indoor system is limited by the limitation of single or dual channels, and multi-stream MIMO (Multiple-Input Multiple-Output) transmission is impossible. The 5G indoor multi-channel system uses different channels of one or more RRUs (Remote Radio Units) to combine multiple transceiver nodes of the distribution system to build a multi-dimensional multi-antenna transceiver system, which can support up to four streams of data to be sent and received simultaneously, and improve the data transmission and reception rate. However, due to the characteristics of the DAS system with a large number of node types and devices, the failure or damage of some devices will cause the multi-channel power imbalance of the indoor system, resulting in a significant reduction in the terminal experience rate.

[0003] In the related technology, the detection and determination methods for channel power imbalance of indoor distributed systems mainly include: the first method: the test personnel test the RSRP (Reference Signal Receiving Power) level values ​​of different channels of the indoor distributed systems on site, and compare the maximum value of the level difference of different channels. When it is greater than a certain value, it is determined that the channel is unbalanced. The process is cumbersome, the cost is high, and batch analysis is not possible. The second method: establish a signaling tracking task in the network management, track the RSSI (Received Signal Strength Indication) values ​​of different channels of a single cell, and then judge whether it is a channel imbalance by comparing the difference between different channels. It cannot be processed in batches.

[0043] The realization of the purpose, functional features and advantages of this application will be further explained in conjunction with embodiments and with reference to the accompanying drawings. DETAILED DESCRIPTION

[0044] It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0045] Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making any creative work shall fall within the scope of protection of this application.

[0046] It should be noted that the descriptions of "first", "second", etc. in this application are only for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in this field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by this application.

[0047] The main solution of the embodiment of the present application is: to provide a multi-channel power imbalance positioning method, by obtaining the rank flow proportion data and the measured average downlink rate value of the cell to be tested, the rank flow proportion data including the rank flow proportion values ​​corresponding to different numbers of flows; based on the rank flow proportion values ​​and proportion thresholds corresponding to the different numbers of flows, determine whether the cell to be tested is a target cell; if the cell to be tested is a target cell, based on the rank flow proportion data and a preset relationship, obtain multiple theoretical downlink rate values ​​of the target cell; wherein the preset relationship includes the relationship between the rank flow proportion parameter and the downlink rate parameter; when the average of the multiple theoretical downlink rate values ​​is greater than the measured average downlink rate value, determine that the cell to be tested is a power imbalance cell.

[0048] The maximum RANK number supported by the 5G indoor distributed system that supports 5G technology has been upgraded from 2 to 4, which means that it supports a maximum of four streams for transmission. The number of streams used for data transmission has increased, and it has also made it more difficult for network personnel to find multi-channel imbalance problems.

[0049] In the prior art, the monitoring methods and shortcomings of room channel imbalance mainly include:

[0050] 1. Indoor test: The test personnel test the RSRP level values ​​of different channels in the indoor area on site, and compare the maximum value of the level difference of different channels. When it is greater than a certain value, it is judged that the channel is unbalanced. The process is cumbersome, the cost is high, and batch analysis is not possible.

[0051] 2. User complaints: Users complain that services cannot be carried out or the rate is slow. Testers conduct on-site testing, which consumes manpower and material resources, takes a long time, and leads to delayed problem discovery. Problems are discovered passively, which reduces customer satisfaction.

[0052] 3. Single site signaling tracking: Establish a signaling tracking task in the network management to track the RSSI values ​​of different channels in a single cell. By comparing the difference between different channels, if it is greater than a certain value, it is judged that the channel is unbalanced and cannot be analyzed in batches.

[0053] At present, most 5G indoor distribution systems adopt the transformation of traditional indoor distribution systems, and use full-band combiners for 5G combining. Therefore, if an abnormality occurs in one channel, the proportion of 5G high-order RANK (high number of flows) traffic will decrease, and the proportion of low-order RANK (low number of flows) traffic will increase, accompanied by poor user experience rate. Therefore, based on this feature, the embodiment of the present application provides a new method for determining channel power imbalance in an indoor distribution system, which uses the relationship between the rank flow proportion value and the proportion threshold corresponding to the different number of flows in the channel unbalanced cell, and the characteristics of the low measured downlink rate value in the channel unbalanced cell to perform cell imbalance determination. Therefore, since this method is completely a data processing, it can simultaneously obtain the rank flow proportion data of multiple cells to be tested, and complete the determination of multiple cells at the same time, thereby achieving the purpose of batch determination. It solves the problem that the method for detecting and determining channel power imbalance in indoor distribution systems in the prior art cannot make batch determinations, and significantly improves the efficiency of locating cell channel power imbalance.

[0054] Among them, RANK is translated as rank in the communication field, which indicates the number of streams in a channel. For example, in 5G technology, the maximum supported RANK is 4, that is, the maximum supported 4-stream transmission. In the embodiment of the present application, the flow proportion corresponding to the rank is called the rank flow proportion value.

The memory 1005 may also be a storage device independent of the aforementioned processor 1001.

[0060] Reference Figure 2 Based on the above hardware, the first embodiment of the present application provides a multi-channel power imbalance positioning method, the method comprising:

[0061] Step S20: Obtain the rank flow ratio data and the measured average downlink rate value of the cell to be tested.

[0062] In the specific implementation process, the area covered by wireless signals in mobile communications is called a cell, which generally refers to the range that a base station signal can cover. The cell to be tested refers to the cell to be determined whether it is an imbalance problem. It can be understood that the cell to be tested can be one or more, and this embodiment does not limit it. Specifically, the cell to be tested can be an area on the same floor or an area across floors, and this application does not make specific limitations.

[0063] Generally speaking, multiple cells correspond to one indoor distributed system, so the cell to be tested in this embodiment also corresponds to at least one indoor distributed system. In this embodiment, the indoor distributed system corresponding to the cell to be tested can be a 5G multi-channel indoor distributed system.

[0064] The rank traffic share data includes the rank traffic share values ​​corresponding to different numbers of flows, that is, the traffic share of ranks with different numbers of flows in the communication process. For the cell corresponding to the 5G multi-channel indoor distributed system, the rank traffic share values ​​corresponding to different numbers of flows can be defined as follows:

[0065] RANK1 (single stream) proportion (%) = single stream downstream transmission TB number / (single stream downstream transmission TB number + dual stream downstream transmission TB number + triple stream downstream transmission TB number + quad stream downstream transmission TB number)

[0066] RANK2 (dual-stream) proportion (%) = dual-stream downstream transmission TB number / (single-stream downstream transmission TB number + dual-stream downstream transmission TB number + three-stream downstream transmission TB number + four-stream downstream transmission TB number)

[0067] RANK3 (three-stream) proportion (%) = three-stream downstream transmission TB number / (single-stream downstream transmission TB number + dual-stream downstream transmission TB number + three-stream downstream transmission TB number + four-stream downstream transmission TB number)

[0068] RANK4 (four-stream) proportion (%) = four-stream downstream transmission TB number / (single-stream downstream transmission TB number + dual-stream downstream transmission TB number + three-stream downstream transmission TB number + four-stream downstream transmission TB number).

[0069] For the cells covered by the 5G multi-channel distributed indoor system, its NR (New Radio) networking mode may include single channel, dual channel and quad channel. Therefore, it can be understood that the cells corresponding to the quad-channel distributed indoor system include RANK1 to RANK4, while the cells corresponding to the dual-channel distributed indoor system only include RANK1 and RANK2. Specifically, when implementing the method of this embodiment, by extracting the number of TB of downlink transmission of different numbers of flows, the rank flow ratio data can be obtained.

[0070] In addition, the measured average downlink rate value is obtained by averaging the actually measured downlink user rate values ​​of each channel in the cell to be measured.

[0071] Step S40: Based on the rank flow proportion values ​​and proportion thresholds corresponding to the different numbers of flows, determine whether the cell to be tested is a target cell.

[0072] In the specific implementation process, the target cell can be understood as a problem cell (i.e., a cell where abnormal proportions of each rank flow occur). Therefore, the judgment can be made based on the relationship between the proportion values ​​of rank flows corresponding to different numbers of flows and the proportion thresholds.

[0073] Specifically, the proportion threshold is a threshold value for determining whether it is a rank flow proportion of the target cell, which can be obtained based on test data (for example, obtained after statistical analysis of the rank flow proportion of the imbalanced problem cell). As an embodiment, before the step of obtaining the rank flow proportion data and the measured average downlink rate value of the cell to be tested, the method also includes: obtaining second sample data, the second sample data including rank flow proportion sample values ​​of several channel imbalanced sample cells and the number of channel imbalanced sample cells corresponding to the rank flow proportion sample values; fitting the rank flow proportion sample values ​​of the several channel imbalanced sample cells and the number of channel imbalanced sample cells corresponding to the rank flow proportion sample values ​​to obtain the proportion threshold.

[0074] Specifically, we use the multi-channel imbalance problem cells found in the 5G indoor distributed test records as samples, extract the RANK traffic share values ​​before and after the problem cells, and analyze the traffic share distribution characteristics corresponding to different RANKs when multi-channel imbalance occurs. For the dual-channel indoor distributed system, we segment the RANK 1 single-flow traffic share value, match the number of problem cells with dual-channel imbalance, and calculate the proportion of dual-channel abnormal cells, and obtain the single-flow traffic share of the dual-channel indoor distributed system and the corresponding proportion of abnormal cells of the dual-channel indoor distributed system, such as Figure 3 .Depend on Figure 3 It can be seen that when dual-channel imbalance occurs, the proportion of single-flow traffic in the cell increases. When the proportion of single-flow traffic is greater than 50%, the proportion of cells with dual-channel imbalance problems shows an obvious inflection point. In other words, for cells with dual-channel indoor distributed systems, when the proportion of single-flow traffic is greater than 50%, it can be preliminarily determined that the dual-channel indoor distributed system of the cell may be a channel-unbalanced cell. Therefore, for the dual-channel indoor distributed system, after repeated fitting and verification, the proportion threshold is 40-60%. Based on the same principle, it can be determined that for the four-channel indoor distributed system, the proportion threshold is 40-60%. In other words, when the proportion of low-order rank traffic corresponding to the number of low-order flows is greater than 40-60%, it is considered to be a channel-unbalanced cell.

[0075] It is understandable that, since the multi-channel indoor distributed system usually includes dual channels and quad channels, the judgment process of whether the dual-channel and quad-channel cells to be tested are target cells is different. Therefore, in one embodiment, before the step of obtaining the rank flow proportion data and the measured average downlink rate value of the cell to be tested, the method also includes: obtaining the number of channels of the indoor distributed system corresponding to the cell to be tested. Specifically, the networking information of the NR cell resources is obtained from the resource management platform to determine the maximum number of channels for the NR cell network. At the same time, the accuracy of the implementation of the method can be improved by obtaining the drawing information through the digital drawing platform to determine whether the dual-channel and quad-channel cover the same area (for example, whether they are on the same floor). If the dual-channel or quad-channel covers across floors, the effect of implementing 5G dual-stream or quad-stream is poor, affecting the accuracy of the method.

[0076] Correspondingly, the step of judging whether the cell to be tested is the target cell based on the rank flow proportion values ​​and proportion thresholds corresponding to the different numbers of flows includes: judging whether the cell to be tested is the target cell based on the number of channels of the indoor distributed system, the rank flow proportion values ​​and proportion thresholds corresponding to the different numbers of flows.

[0077] In one case, the number of channels of the indoor distributed system is 2 (i.e., dual channels), and the rank flow proportion values ​​corresponding to the different numbers of flows include a single-flow flow proportion value and a dual-flow flow proportion value; the step of judging whether the cell to be tested is the target cell based on the number of channels of the indoor distributed system, the rank flow proportion values ​​corresponding to the different numbers of flows, and the proportion threshold value includes: judging whether the single-flow flow proportion value is greater than the proportion threshold value; if so, the cell to be tested is the target cell. It can be understood that due to the increase in the power difference between multiple channels of the unbalanced cell, the flow proportion of the high-order RANK will decrease, and the flow proportion of the low-order RANK will increase. Therefore, for the dual-channel case, if the single-flow flow proportion value is greater than the proportion threshold value, it can be judged that the flow proportion of the low-order RANK has increased, and then, it is preliminarily judged that the cell to be tested is the target cell.

[0078] In another case, the number of channels of the indoor distributed system is 4, and the rank flow proportion data includes a single-flow flow proportion value, a dual-flow flow proportion value, a three-flow flow proportion value and a four-flow flow proportion value; the step of judging whether the cell to be tested is the target cell based on the number of channels of the indoor distributed system, the rank flow proportion values ​​corresponding to the different numbers of flows and the proportion threshold value includes: judging whether the sum of the single-flow flow proportion value and the dual-flow flow proportion value is greater than the proportion threshold value; if so, the cell to be tested is the target cell. It can be understood that due to the increase in the power difference between multiple channels of the unbalanced cell, the flow proportion of the high-order RANK will decrease, and the flow proportion of the low-order RANK will increase. Therefore, for the case of four channels, if the sum of the single-flow flow proportion value and the dual-flow flow proportion value is greater than the proportion threshold value, it can be judged that the flow proportion of the low-order RANK has increased, and then, it is preliminarily judged that the cell to be tested is the target cell.

[0079] However, factors such as the unavailability of the radio frequency unit and the presence of external jammers may also cause the high-order RANK traffic ratio to decrease and the low-order RANK traffic ratio to increase. Therefore, S40 can only preliminarily determine that the cell to be tested is the target cell. Analysis shows that in addition to the characteristics of the high-order RANK traffic ratio decreasing and the low-order RANK traffic ratio increasing, the unbalanced cell is also accompanied by poor user experience rate. Therefore, it is necessary to execute S60-S80 to accurately locate the unbalanced cell.

[0080] Step S60: If the cell to be tested is a target cell, multiple theoretical downlink rate values ​​of the target cell are obtained based on the rank traffic proportion data and a preset relationship.

[0081] Wherein, the preset relational expression includes the relation between the rank flow ratio parameter and the downlink rate parameter. ;

[0082] As an embodiment, before the step of obtaining the rank flow ratio data and the measured average downlink rate value of the cell to be tested, the method further includes:

[0083] Acquire first sample data, where the first sample data includes rank flow ratio data and downlink rate data of several sample cells in a sample area;

[0084] The rank flow ratio data and downlink rate data of the plurality of sample cells are fitted to obtain the preset relationship. The cell to be tested.

[0085] In the specific implementation process, the sample area can be an administrative area, such as an area covered by a province, a city, etc. Specifically, before the execution of step S20, the RANK traffic share value and the downlink rate value of the NR cell of the entire network can be extracted in the sample area, and the RANK traffic share value of different numbers of flows can be divided into intervals. The downlink rate value corresponding to different RANK traffic share values ​​is used for curve fitting to obtain the polynomial relationship between the RANK traffic share parameter and the downlink user rate parameter. Among them, after averaging each downlink rate value, the downlink user average rate value is obtained, and the downlink user average rate value (Mbps) = the number of downlink bytes on the user plane of the cell * 8 / the total service duration of the downlink data sent by the PDCP layer of the cell.

[0086] Since the preset relationship is obtained in advance, it can be used repeatedly for multiple judgments, which improves the efficiency of the judgment method of this embodiment. At the same time, the sample data includes the rank flow ratio data and downlink rate data of several sample cells in the sample area, and the preset relationship fitted is more accurate, so that the accuracy of fault judgment is higher.

[0087] It should be noted that, since the performance and characteristics of the communication network systems belonging to the same operator are basically the same, the sample area and the cell to be tested can be selected at will and are not restricted. However, in order to improve the accuracy of the determination method of this embodiment, the sample area can be related to the cell to be tested, that is, the cell to be tested belongs to the sample area. For example, in order to make an unbalanced fault determination for the cell in City A, Province B to which City A belongs can be pre-selected as the sample area. Of course, if the amount of calculation is not considered, the whole country can also be selected as the sample area.

[0088] In one embodiment, the sample area includes the cell to be tested, the sample area is a province, and the cell to be tested is a city, county or cell included in the province. Specifically, after fitting the rank flow ratio data and downlink rate data of several sample cells in the province, the following preset relationship is obtained:

[0093] Among them, a1 is the single-stream traffic proportion parameter, v1 is the first downlink rate parameter corresponding to the single stream; a2 is the dual-stream traffic proportion parameter, v2 is the second downlink rate parameter corresponding to the dual stream; a3 is the triple-stream traffic proportion parameter, v3 is the third downlink rate parameter corresponding to the three streams; a4 is the quad-stream traffic proportion parameter, v4 is the fourth downlink rate parameter corresponding to the quad-stream.

[0094] Since the sample area includes the cell to be tested, that is, the preset relationship used for unbalanced fault detection of the cell to be tested is obtained based on the data of the sample area to which it belongs, the data features of the two are closer, and the preset relationship obtained based on this fitting is more accurate. Therefore, the accuracy of fault judgment is also higher.

[0095] After obtaining the preset relationship, the rank flow ratio values ​​corresponding to different numbers of flows in the rank flow ratio data are substituted into the preset relationship, and then multiple downlink rate values ​​corresponding to channels with different numbers of flows can be obtained.

[0096] Since the multi-channel indoor distributed system includes dual-channel and quad-channel situations, based on the rank flow proportion data and the preset relationship, obtaining multiple theoretical downlink rate values ​​of the target cell can be divided into the following two situations:

[0097] In one embodiment, the multi-channel indoor distributed system is a dual-channel indoor distributed system, that is, it includes a single-stream channel and a dual-stream channel; the rank flow ratio data includes a single-stream flow ratio value and a dual-stream flow ratio value. The step of obtaining multiple theoretical downlink rate values ​​of the target cell based on the rank flow ratio data and a preset relationship includes: obtaining a first theoretical downlink rate value corresponding to the single-stream channel and a second theoretical downlink rate value corresponding to the dual-stream channel based on the single-stream flow ratio value, the dual-stream flow ratio value and the preset relationship.

[0098] In one embodiment, the multi-channel indoor distributed system is a four-channel indoor distributed system, that is, it includes a single-stream channel, a dual-stream channel, a triple-stream channel and a quad-stream channel; the rank flow ratio data includes a single-stream flow ratio value, a dual-stream flow ratio value, a triple-stream flow ratio value and a quad-stream flow ratio value. The step of obtaining multiple theoretical downlink rate values ​​of the target cell based on the rank flow ratio data and a preset relationship includes: based on the single-stream flow ratio value, the dual-stream flow ratio value, the triple-stream flow ratio value, the quad-stream flow ratio value and the preset relationship, obtaining a first theoretical downlink rate value corresponding to the single-stream channel, a second theoretical downlink rate value corresponding to the dual-stream channel, a third theoretical downlink rate value corresponding to the triple-stream channel and a fourth theoretical downlink rate value corresponding to the quad-stream channel.

[0099] Step S80: When the average of the multiple theoretical downlink rate values ​​is greater than the measured average downlink rate value, determine that the cell to be measured is a power imbalance cell.

[0100] In a specific implementation process, the average of the plurality of theoretical downlink rate values ​​is obtained by arithmetically averaging the plurality of theoretical downlink rate values. Measured average downlink rate value Measured average downlink rate value.

[0101] Corresponding to S60, since the multi-channel room distribution system includes two-channel and four-channel cases, the measured average downlink rate value S80 can also be divided into the following two cases:

[0102] In one embodiment, the multi-channel indoor distributed system is a dual-channel indoor distributed system, and the rank flow proportion data includes a single-flow flow proportion value and a dual-flow flow proportion value. When the measured average downlink rate value is greater than the average of the multiple theoretical downlink rate values, the step of determining that the cell to be tested is a power imbalance cell includes: when the average of the first theoretical downlink rate value and the second theoretical downlink rate value is greater than the measured average downlink rate value, it represents that the user rate of the dual-channel cell is low, and therefore, it can be determined that the channel power of the multi-channel indoor distributed system is unbalanced.

[0103] That is, (w1+w2) / 2>V, where V represents the measured average downlink rate value.

[0104] In one embodiment, the multi-channel indoor distributed system is a four-channel indoor distributed system, and the rank flow proportion data includes a single-flow flow proportion value, a dual-flow flow proportion value, a three-flow flow proportion value, and a four-flow flow proportion value. When the measured average downlink rate value is greater than the average of the multiple theoretical downlink rate values, the step of determining that the cell to be tested is a power imbalance cell includes: when the average of the first theoretical downlink rate value, the second theoretical downlink rate value, the third theoretical downlink rate value, and the fourth theoretical downlink rate value is greater than the measured average downlink rate value, determining that the channel power of the multi-channel indoor distributed system is unbalanced.

[0105] That is, (w1+w2+w3+w4) / 2>V, wherein w1 represents the first theoretical downlink rate value obtained by substituting the single-stream traffic proportion value into the preset relationship formula, w2 represents the second theoretical downlink rate value obtained by substituting the single-stream traffic proportion value into the preset relationship formula, w3 represents the third theoretical downlink rate value obtained by substituting the single-stream traffic proportion value into the preset relationship formula, w4 represents the fourth theoretical downlink rate value obtained by substituting the single-stream traffic proportion value into the preset relationship formula, and V represents the measured average downlink rate value.

[0106] It should be understood that the above is only an example and does not constitute any limitation to the technical solution of the present application. Those skilled in the art can make settings based on needs in actual applications and no limitation is made here.

[0107] It is not difficult to find out from the above description that the present embodiment provides a new method for determining channel power imbalance in an indoor distributed system, by obtaining the rank flow ratio data and the measured average downlink rate value of the cell to be tested, the rank flow ratio data includes the rank flow ratio values ​​corresponding to different numbers of flows; based on the rank flow ratio values ​​and the ratio threshold values ​​corresponding to the different numbers of flows, determine whether the cell to be tested is a target cell; if the cell to be tested is a target cell, based on the rank flow ratio data and a preset relationship, obtain multiple theoretical downlink rate values ​​of the target cell; wherein the preset relationship includes the relationship between the rank flow ratio parameter and the downlink rate parameter; when the average of the multiple theoretical downlink rate values ​​is greater than the measured average downlink rate value, determine that the cell to be tested is a power imbalance cell. It can be seen that the present application provides a new method for locating channel power imbalance in an indoor distributed system, and makes a cell imbalance determination by utilizing the relationship between the rank flow ratio values ​​and the ratio threshold values ​​corresponding to different numbers of flows in the channel unbalanced cell, and the characteristics of the low measured downlink rate value in the channel unbalanced cell. Therefore, since this method is completely about data processing, it can simultaneously obtain the rank flow ratio data of multiple cells to be tested, and simultaneously complete the determination of multiple cells, thereby achieving the purpose of batch determination. The problem that the method for detecting and determining channel power imbalance in indoor distributed systems in the prior art cannot make batch determinations is solved, and the efficiency of detecting and determining channel power imbalance in indoor distributed systems is significantly improved.

[0108] In addition, through the determination method of this embodiment, it is possible to proactively carry out evaluation of cells with multi-channel imbalance problems, with strong proactive discovery capabilities. Problems can be discovered without on-site testing or relying on customer complaints, thus truly achieving cost reduction and efficiency improvement.

[0109] In a specific example, SFNR_112 below the 16th floor of Xiaoshan XXX belongs to a 5G dual-channel indoor distributed system. Among them, the proportion of single-stream traffic is 85.52%>50%, and after the rank traffic proportion data is brought into the preset polynomial, the average of multiple theoretical downlink rate values ​​obtained is greater than 10Mbps, while the measured downlink average rate value is lower than 10Mbps. The LTE (Long Term Evolution) dual-channel indoor distributed system cell corresponding to the cell is matched. It is found that the measured downlink user average rates of the three LTE dual-channel indoor distributed system cells corresponding to the site are all lower than 10%. According to the steps S20-S80 of the above embodiment, it is judged to be a multi-channel imbalance problem cell.

[0110] On-site troubleshooting revealed that the 5G dual-stream failed due to reverse jumper connection during 5G cell combining. The LTE dual-stream failed due to a broken shaft trunk and serial connection of cell combining (one jumper connection was reversed between cells 133 and 139).

[0111] The effect after rectification is significantly improved

[0112] Through rectification of problematic devices on site, the dual-stream indicators of 5G and LTE cells changed significantly after rectification. The proportion of 5G dual-stream increased from 14.48% to 59.1%, and the proportion of LTE dual-stream increased from 6.9% to 86.8%.
