[0021] The embodiments of the present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0022] It should be noted that the terms "first", "second", etc. in the specification and claims of this application and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence.

[0023] A base station is a device within a site that is responsible for sending and receiving wireless signals. Currently, the connection between the base station antenna and the remote radio unit (RRU) can be divided into the following scenarios:

[0024] 1. One-to-one connection scenario between RRU and antenna

[0025] That is, each RRU can be directly connected to a single antenna. This scenario is simple to configure and can be used in scenarios with a small coverage area or low signal requirements.

[0026] 2. Multiple RRUs are connected to the same multi-band antenna, which can include the following scenarios:

[0027] A) RRUs of different frequency bands are connected to the same multi-mode antenna

[0028] That is, each RRU processes a different frequency band, and all RRUs can share the same multi-mode antenna, which can support signal transmission of multiple frequency bands at the same time.

[0029] B) Antenna splitting scenario: RRUs in different cells are connected to different split ports of the same antenna.

[0030] That is, the antenna is physically divided into multiple parts (split ports), each part can be controlled independently, and different cell RRUs are connected to different split ports of the same antenna to achieve more refined signal control and coverage.

[0031] 3. The same RRU is connected to different antennas, which can include the following scenarios:

[0032] A) One RRU has different transmit / receive (TX / RX) ports connected to different antennas

[0033] Different transmit / receive ports of the RRU are connected to different antennas and can be used to implement more complex signal processing and coverage strategies.

[0034] B) Different TX / RX ports of an RRU are connected to different split ports of the same antenna.

[0035] Multiple ports of the RRU are connected to different split ports of the same antenna. The RRU can use antenna splitting technology to optimize signal coverage.

[0036] There are two types of reverse antenna connection:

[0037] 1. Big mandarin duck:

[0038] It can mean that the RRU of the entire cell or sector is incorrectly connected to the antenna of another cell or sector, for example, the RRU of cell A is connected to the antenna of cell B. This situation will cause signal coverage errors and affect the user communication quality.

[0039] 2. Little Mandarin Duck:

[0040] This may mean that some of the jumpers of the RRU are incorrectly connected to the wrong antenna. This local incorrect connection may cause signal interference or uneven coverage.

[0041] The embodiment of the present application can be used for the RRU tower scene, that is, the RRU is connected to the antenna through a short jumper, and there is no situation where some jumpers of the RRU are mistakenly connected to the wrong antenna, that is, there is no small mandarin duck fault scenario where the antenna is connected reversely. However, there is a large mandarin duck fault phenomenon where the optical fiber on the baseband unit (BBU) side and the RRU side is connected reversely.

[0042] For the Big Mandarin Duck fault phenomenon, the current troubleshooting methods include the following:

[0043] (1) Collect data through on-site road testing, and then determine whether there is a double-line problem based on the collected data;

[0044] However, this method is extremely costly in terms of time, manpower and financial resources. Real-time data also requires timely feedback from the front desk, which requires high skills of the personnel.

[0045] (2) Collect the received signal strength indicator (RSSI) data through the backend network management to determine whether there is a problem with the double-wire cable;

[0046] However, this method usually requires the base station to run for a period of time before sufficient data can be collected for judgment, which will affect user perception and seriously affect network indicators.

[0047] (3) On-site inspection: This method is labor-intensive and time-consuming.

[0048] Therefore, the above methods all have the problems of being time-consuming, high manpower and material costs, and the inspection methods mainly based on manual work also have the problem of low efficiency.

[0049] In response to the above-mentioned technical problems, the present application proposes a method for detecting the reverse connection of the base station cell antenna. The technical concept is that the serial number (Serial Number, SN) of the RRU running at the site can be obtained from the network management through the background site interface of the mobile terminal, and the actual RRU SN information on site can be identified by the front-end of the mobile terminal. The foreground and background RRUSNs can be compared to detect whether there are RRUs that do not belong to the current cell. For example, if there are, it means that there is a reverse connection phenomenon. The reverse antenna connection problem can be detected quickly, accurately and simply, which solves the problem of time-consuming and high manpower and material costs in the related technology based on the collection of road test data and manual judgment of whether the site has a reverse antenna connection.

[0050] The method embodiments provided in the embodiments of the present application can be executed in a mobile terminal, a computer terminal or a similar computing device. Taking running on a mobile terminal as an example, Figure 1 1 is a hardware structure block diagram of a mobile terminal of a method for detecting reverse connection of a base station cell antenna according to an embodiment of the present application. Figure 1 As shown, the mobile terminal may include one or more ( Figure 1 Only one is shown in the figure) a processor 102 (the processor 102 may include but is not limited to a processing device such as a microprocessor MCU or a programmable logic device FPGA) and a memory 104 for storing data, wherein the mobile terminal may also include a transmission device 106 and an input / output device 108 for communication functions. It can be understood by those skilled in the art that Figure 1 The structure shown is only for illustration and does not limit the structure of the mobile terminal. Figure 1 More or fewer components as shown, or with Figure 1 Different configurations are shown.

[0051] The memory 104 can be used to store computer programs, for example, software programs and modules of application software, such as the computer program corresponding to the detection method of the reverse connection of the base station cell antenna in the embodiment of the present application. The processor 102 executes various functional applications and data processing by running the computer program stored in the memory 104, that is, to implement the above method. The memory 104 may include a high-speed random access memory, and may also include a non-volatile memory, such as one or more magnetic storage devices, flash memory, or other non-volatile solid-state memory. In some instances, the memory 104 may further include a memory remotely arranged relative to the processor 102, and these remote memories may be connected to the mobile terminal via a network. Examples of the above-mentioned network include, but are not limited to, the Internet, an intranet, a local area network, a mobile communication network, and combinations thereof.

[0052] The transmission device 106 is used to receive or send data via a network. The specific example of the above network may include a wireless network provided by a communication provider of the mobile terminal. In one example, the transmission device 106 includes a network adapter (Network Interface Controller, referred to as NIC), which can be connected to other network devices through a base station so as to communicate with the Internet. In one example, the transmission device 106 can be a radio frequency (RF) module, which is used to communicate with the Internet wirelessly.

[0053] Figure 2 is a system architecture diagram of the antenna reverse connection detection method according to an embodiment of the present application. The embodiment of the present application can be operated on Figure 2 In the network architecture shown in Figure 2 As shown, the network architecture includes: base stations, network management platforms (i.e., network management), and terminals.

[0054] Among them, the base station is a device within the site that is responsible for sending and receiving wireless signals. The base station may include BBU, RRU and antenna, etc. A site can have multiple base stations to provide wider coverage or serve more users.

[0055] The network management system can be used to store and record the sites that have established links with the network management system and the data related to the antennas, cells, RRUs, etc. in the sites.

[0056] The terminal may be an electronic device with computing functions, such as a computer, a mobile phone, etc. The terminal may be used to obtain relevant data of antennas, cells, RRUs, etc. recorded in the network management.

[0057] As a feasible method, the RRUs of the sites involved in this implementation example can all be in the tower-up state, that is, a short jumper is used between the RRU and the antenna, that is, the phenomenon of the RRU and the antenna being connected reversely does not exist in this embodiment. In this implementation example, the reverse connection of the antenna refers to the actual network deployment, in which the RRU and the BBU port are connected reversely (the fault phenomenon is equivalent to the reverse connection of the antenna and the RRU). For example, all the RRUs of the first cell are connected to the BBU ports of the second cell, or the ports of the second cell are connected to the ports of the first cell.

[0058] In this embodiment, a method for detecting reverse connection of a base station cell antenna running on the above mobile terminal or system architecture is provided. Figure 3 is a flow chart of a method for detecting reverse connection of a base station cell antenna according to an embodiment of the present application, such as Figure 3 As shown, the process includes the following steps:

[0059] Step S301: for a current site, in response to a page operation of selecting a target cell ID, obtaining a first remote radio unit RRU serial number corresponding to the target cell ID.

[0060] In an embodiment of the present application, the base station side can pre-set the correspondence between the cell ID (cell number, an identifier used to identify the cell at the logical or management level), RRU serial number, cell azimuth, physical cell identification code (Physical Cell Identity, PCI), etc., and synchronize the correspondence to the terminal side background for subsequent fault identification or information updating; the terminal side can pre-provide multiple cell IDs corresponding to the site on the front-end page of the terminal device (i.e., user interface UI) for user selection.

[0061] As an example, the terminal can obtain the RRU serial number corresponding to the target cell ID in response to the page operation of selecting the target cell ID, and can automatically address and write the obtained RRU serial number into the corresponding position in the background according to the preset correspondence between the cell ID and the RRU serial number.

[0062] As an example, a user interface managed by the terminal device may provide a control or component corresponding to each cell ID, so that the user can trigger the selection of a target cell ID.

[0063] For example, Figure 4 is a schematic diagram of a UI interface of a terminal according to an embodiment of the present application. Multiple controls can be set on the UI interface, each control corresponds to a cell ID, and the number on the control represents the cell ID. For example, Figure 4 As shown, "1" on the control can represent the first cell (or the first sector), "2" can represent the second cell (or the second sector), "3" can represent the third cell (or the third sector), "4" can represent the fourth cell (or the fourth sector), etc. The user can trigger the selection of the target cell ID by clicking the control on the page of the terminal device.

[0064] In an exemplary embodiment, the acquiring the first remote radio unit RRU serial number corresponding to the target cell ID includes:

[0065] Identify the RRU serial number QR code on the RRU device corresponding to the target cell ID to obtain the first RRU serial number corresponding to the target cell ID;

[0066] According to the preset correspondence between the cell ID and the RRU serial number, the field name and the data type, the first RRU serial number is filled into the corresponding field position in the table template.

[0067] As an example, the terminal may also provide a code scanning function for scanning the QR code of the RRU serial number on the RRU device to obtain the RRU serial number. Figure 4 As shown, a "scan code" control can also be provided on the UI interface of the terminal. The user can click the "scan code" control to trigger the terminal to identify the RRU serial number QR code on the RRU device corresponding to the target cell ID to obtain the first RRU serial number corresponding to the target cell ID.

[0068] In the embodiment of the present application, the first RRU serial number may be an RRU serial number obtained by a user at a site by scanning an RRU serial number QR code on an RRU device, that is, an RRU site serial number.

[0069] As an example, after the user triggers a page operation for selecting a target cell ID, the user may scan an RRU serial number QR code on an RRU device to obtain the first RRU serial number.

[0070] As an example, the terminal may pre-set a table template, which may include header information, which may include field names and data types. The header information may be used to determine a target location for data filling, for example, a target location for filling the first RRU sequence number.

[0071] As an example, the first RRU serial number may be filled into a corresponding field position in the table template according to a preset correspondence between the cell ID and the RRU serial number, the field name and the data type in the header information.

[0072] In an exemplary embodiment, before acquiring the first radio remote unit RRU serial number corresponding to the target cell ID, the method further includes:

[0073] The correspondence between the cell ID and the color of the color card is obtained from the network management and saved locally, so that the user can select the target cell ID on the page based on the color of the color card.

[0074] As an example, the base station side can also pre-configure the one-to-one correspondence between the color card color and the cell azimuth angle, that is, each cell azimuth angle can correspond to a color card color. The network management can generate a correspondence between the cell ID and the color card color based on the correspondence between the cell azimuth angle and the cell ID, and synchronize the correspondence to the terminal side.

[0075] As an example, the terminal side can obtain the correspondence between the cell ID and the color of the color card and save it to the background so that the user can select the target cell ID on the page according to the color of the color card, and then obtain the first RRU serial number corresponding to the target cell ID by identifying the RRU serial number QR code on the RRU device corresponding to the target cell ID, and fill it into the corresponding field position in the table template.

[0076] For example, Figure 5 is a schematic diagram of the structure of a base station application according to an embodiment of the present application, such as Figure 5 As shown, a base station can be composed of multiple devices, including BBU, RRU and antenna, etc. Among them, a site can have multiple base stations to provide wider coverage or serve more users.

[0077] Among them, BBU is the central processing unit of the base station. BBU and RRU can be connected through optical fiber or cable. BBU can be responsible for digital signal processing, including modulation and demodulation, encoding and decoding, signal processing algorithms, etc. BBU sends the processed digital signal to RRU for RF signal conversion.

[0078] The RRU is located between the BBU and the antenna. The RRU can be connected to the antenna via a cable (such as a short jumper) and is responsible for converting the digital signal sent by the BBU into an RF signal and sending it to the air through the antenna. At the same time, the RRU can also receive the RF signal from the antenna and convert it back into a digital signal and send it to the BBU for processing. The RRU is equipped with a QR code of the RRU SN, which is convenient for operators to scan and obtain the RRU serial number.

[0079] The antenna is the wireless signal transmitting and receiving part of the base station. It can radiate the RF signal converted by the RRU into the air to cover a specific geographical area, while receiving the signal sent by the mobile terminal and transmitting it to the RRU.

[0080] For example, assume that the configuration of the base station is a three-sector base station, that is, the base station configuration includes three sectors, each sector covers a 120-degree geographical area, and the three sectors together constitute 360-degree full coverage. Each sector can correspond to at least one cell, and each cell can be covered by at least one RRU. Each RRU on the base station can support multiple transmission channels and multiple reception channels. The cells corresponding to each sector can be numbered (i.e., assigned cell IDs). For example, the cells can be numbered in advance in a clockwise direction according to the cell azimuth, and the numbering is the first cell, the second cell, the third cell, the fourth cell, and so on, until the numbering of all cells with full coverage is completed. The color card color can be set in sequence according to the cell azimuth to correspond to the cell ID one by one, and different colors define different cells. For example, the color card color corresponding to the first cell can be set to yellow, the color card color corresponding to the second cell can be set to red, the color card color corresponding to the third cell can be set to blue, and so on.

[0081] Among them, the sequential numbering can make the order of the azimuths correspond to the layout of the cells, which helps technicians to quickly locate and identify the cells.

[0082] It should be noted that the above process is the process of color coding of cell azimuth angles. The color coding of cell azimuth angles is a visualization tool that can be used to associate the physical direction of the cell with the color. For example, if the first cell faces north, it can be represented by yellow, the second cell faces east, it can be represented by red, and so on. This color coding helps field technicians quickly identify the physical direction of each cell or sector.

[0083] Step S302: acquiring base station configuration information from a network management system connected to the base station of the site, wherein the base station configuration information includes the target cell ID and a second RRU serial number corresponding to the target cell ID.

[0084] In the embodiment of the present application, the terminal side can establish a data interface connection with the network management and site background system in advance to obtain base station configuration information, wherein the base station configuration information may include cell PCI, cell ID, RRU serial number corresponding to cell ID, etc.

[0085] As an example, the second RRU serial number in the embodiment of the present application is an RRU configuration serial number obtained from a network management.

[0086] In an exemplary embodiment, it also includes:

[0087] According to the base station configuration information and a preset table template, the base station configuration information is filled into the table template.

[0088] As an example, the terminal side can save the base station configuration information obtained from the network management to the background, for example, return the base station configuration information in XML format, and then convert it into an internal data type and save it to a preset table template in the background.

[0089] In an exemplary embodiment, the table template includes header information, the header information includes a field name and a data type corresponding to the base station configuration information; and filling the base station configuration information into the table template according to the base station configuration information and a preset table template includes:

[0090] According to the field name and the data type, the base station configuration information is filled into the corresponding field position in the table template.

[0091] As an example, the collected base station configuration information needs to be converted and formatted according to a preset table template format to ensure that the data can be correctly mapped to the cells in the template.

[0092] As an example, the preset table template may include header information, and the header information may include field names and data types corresponding to the base station configuration information. For example, the field names may include "cell ID", "RRU serial number", etc., and the XML format base station configuration information returned from the network management may be parsed and converted into the data type of the header information, and the required data type information may be obtained and filled into the corresponding field position in the table template.

[0093] As an example, the position of each field in the table may be indicated by a preset row number and column number. For example, the first column may be used to indicate a cell ID, the second column may be used to indicate an RRU sequence number, and so on.

[0094] As an example, the cell ID obtained from the network management system may be matched with the cell ID field in the table template to determine the field position of the cell ID.

[0095] As an example, after determining the cell ID, the field position filled with the RRU serial number obtained from the network management can be determined according to the correspondence between the cell ID and the RRU serial number and the "RRU serial number" field name in the header information.

[0096] In an exemplary embodiment, the base station configuration information further includes at least one of the following: a cell physical cell identifier PCI, frequency band information, a cell azimuth, a baseband processing unit BBU board slot number, and a port number.

[0097] Exemplarily, the base station configuration information may be used in the network planning phase to ensure correct deployment of base stations and optimize network performance.

[0098] As an example, the physical cell identification code PCI is used to uniquely identify a cell at the physical level, and the terminal can identify and distinguish different cells based on the PCI. The PCI code of each cell can be preset to correspond to the cell ID one by one. For example, the PCI code of the first cell is A, and the PCI code of the second cell is B. Such a correspondence enables the terminal to correctly identify and connect to the corresponding cell.

[0099] As an example, the frequency band information refers to the radio frequency range used by the base station, and the terminal can ensure that the antenna is correctly configured based on the frequency band information to match the corresponding frequency band.

[0100] As an example, the BBU board slot number is the physical location number inside the base station for installing the BBU board. Each slot has a specific function and can be installed with different hardware modules, such as a processing module, a power module, etc. The terminal can identify and maintain the hardware configuration inside the BBU based on the BBU board slot number, which facilitates subsequent fault diagnosis and performance optimization.

[0101] As an example, the port number is a number used inside the base station to distinguish different communication interfaces. It usually refers to the port number between the BBU and the RRU. Each port corresponds to a specific communication path. The terminal can identify the specific port to which the antenna is connected based on the port number to ensure that the antenna is connected to the correct communication path. The correct configuration of the port number is crucial to ensuring the accuracy and efficiency of data transmission.

[0102] As an example, the cell azimuth may refer to the orientation of a base station antenna, and may be used to determine the direction and range of signal coverage. Correct azimuth configuration may optimize signal coverage, reduce signal interference, and improve communication quality.

[0103] For example, the following table 1 shows part of the information in the table template where the site identifier is T_RNG7171 and each base station eNodeB identifier of the site is RNG7171X_1NB01, RNG7171X_2NB01, etc., stored in the terminal background, as shown in the following table 1:

[0104] Table 1

[0105]

[0106] Among them, "Frequency Band", "Cell ID", "Azimuth", "PCI", "Board Slot Number - Port Number", "Color Card Identification", "RRU Configuration Serial Number", "RRU Site Serial Number", and "Match Result" in Table 1 are the field names of the header in the table template. The RRU configuration serial number is the second RRU serial number obtained from the network management, and the RRU site serial number is the first RRU serial number obtained by the user at the site by scanning the RRU serial number QR code on the RRU device.

[0107] The terminal backend can match the RRU configuration serial number in the table template with the RRU site serial number to generate a matching result. If the matching result is "TURE", it means that the RRU configuration serial number is consistent with the RRU site serial number, and the antenna of the cell is not connected reversely; if the matching result is "FALSE", it means that the RRU configuration serial number is inconsistent with the RRU site serial number, and the antenna of the cell is connected reversely.

[0108] Step S303: Match the first RRU serial number with the second RRU serial number to obtain a matching result.

[0109] As an example, the first RRU serial number in the table template may be compared with the second RRU serial number to determine whether the first RRU serial number matches or is consistent with the second RRU serial number to obtain a matching result.

[0110] The matching results may include matches and mismatches.

[0111] Step S304: Determine the detection result of the reverse connection of the target cell antenna according to the matching result.

[0112] In this embodiment of the present application, it can be determined whether the target cell antenna is connected reversely according to the matching result of step S303.

[0113] In an exemplary embodiment, determining the detection result of the reverse connection of the target cell antenna according to the matching result includes:

[0114] When the matching result is a match, determining that the detection result is that the target cell antenna is not connected reversely;

[0115] When the matching result is a mismatch, it is determined that the detection result is that the target cell antenna is connected reversely.

[0116] As an example, if the matching result is a match, that is, the first RRU serial number is the same as the second RRU serial number, it can be said that the antenna is installed correctly and not connected reversely, and the detection result is that the target cell antenna is not connected reversely; if the matching result is a mismatch, it can be said that the antenna is connected reversely, and the detection result is that the target cell antenna is connected reversely.

[0117] In the embodiment of the present application, after the base station of the site is installed and put into operation, the corresponding base station configuration data of the background can be directly read through the mobile application, and compared with the current site information obtained by scanning the code to determine whether there is a cell antenna reverse connection fault. The site does not need to run for an additional period of time, which greatly improves the detection efficiency. Moreover, it only needs to scan the code to obtain the RRU serial number of the current site, and the base station configuration data obtained by the background from the network management can be automatically matched with it and output the corresponding detection results, which greatly reduces the detection cost. Moreover, the front-end operator only needs a simple scan and identification to obtain the result through the tool's automatic matching. The operation method is simple and the skill requirements for the operator are low.

[0118] The following two examples further illustrate the detection process of reverse connection of cell antennas and the operation flow of terminal applications:

[0119] Example 1: Antenna reverse connection detection process

[0120] Figure 6 is a flow chart of detecting reverse connection of an antenna according to an embodiment of the present application, such as Figure 6 As shown, the following steps may be specifically included:

[0121] 1) The mobile terminal can start the antenna reverse connection detection task on the site side;

[0122] For example, the front desk operator may trigger the antenna reverse connection detection task on the terminal side after installing the base station at the site.

[0123] 2) The mobile terminal UI interface provides a code scanning function to scan the QR code of the RRU serial number of the on-site site;

[0124] Exemplarily, the terminal may provide a cell ID selection page (i.e., a UI interface), allowing a front-end operator to select a target cell ID in the UI interface; the UI interface may also provide a code scanning function, by scanning the QR code of the RRU serial number, the actual RRU serial number of the current site may be obtained.

[0125] 3) Obtain the actual RRU serial number on site, and synchronize the obtained RRU serial number to the built-in fault detection program in the terminal background;

[0126] Exemplarily, the terminal backend may have a built-in fault detection program, which may be used to detect whether the antenna has a reverse connection fault based on the site information obtained on-site at the front end and the base station configuration information obtained from the network management.

[0127] Exemplarily, a table template may be preconfigured in the fault detection program, and the scanned RRU serial number may be filled into a corresponding cell position in the table template.

[0128] 4) The terminal can obtain the correspondence between the cell ID and the RRU serial number, PCI, cell azimuth, etc. from the base station, and save the correspondence to the background built-in fault detection program;

[0129] Exemplarily, the fault detection program may set a table template based on the corresponding relationship.

[0130] 5) The terminal can obtain the base station configuration information of the site from the network management. The base station configuration information may include RRU serial number, cell ID, PCI and other information, and synchronize it to the built-in fault detection program in the terminal background;

[0131] Exemplarily, the base station configuration information obtained from the network management may be saved in a table template in the fault detection program so that the fault detection program can compare the information and detect the fault.

[0132] 6) The fault detection program in the terminal can match the RRU serial number obtained on site with the corresponding RRU serial number in the base station configuration information and output the matching result;

[0133] Exemplarily, the fault detection program may compare the RRU serial number on the base station side obtained from the network management with the RRU serial number obtained by scanning on the site side.

[0134] 7) According to the matching results, determine whether the antenna is connected reversely;

[0135] The matching result includes RRU serial number matching and RRU serial number mismatching. If the matching result is RRU serial number matching, it can be determined that the antenna is not connected reversely; if the matching result is RRU serial number mismatching, it can be determined that the antenna is connected reversely.

[0136] Exemplarily, the matching result may be output in a table format, showing the result of data comparison, so as to facilitate the discovery of reverse connection phenomenon.

[0137] Based on the above steps in Example 1, the efficiency and accuracy of base station detection are improved, which helps to timely discover and solve problems such as reverse antenna connection, and ensure the stable operation of the communication network.

[0138] Example 2: Operational process of terminal application

[0139] Figure 7 FIG. 1 is a schematic diagram of the operation flow of a terminal application according to an embodiment of the present application, taking a mobile terminal as an example. Figure 7 As shown, the front desk operator can perform the following steps to complete the test:

[0140] S701, entering the mobile terminal UI interface;

[0141] For example, when performing antenna reverse connection detection, the front desk operator can distinguish different cells through the color card identification on the on-site cable or optical fiber or RRU equipment according to the correspondence between the preset color card colors and the cell ID to confirm the target cell.

[0142] Exemplarily, after confirming the target cell, the front desk operator can enter the UI interface of the mobile terminal.

[0143] S702, selecting a target cell;

[0144] Exemplarily, the UI interface may provide controls or components corresponding to multiple cell IDs for the front desk operator to select the target cell ID. The front desk operator may select the target cell by clicking the control or component of the target cell ID in the page.

[0145] S703, click Scan to enter the site cell RRU serial number;

[0146] Exemplarily, the UI interface may also provide a code scanning function. After selecting the target cell, the front desk operator may click code scanning to scan the QR code of the RRU serial number of the target cell at the current site to obtain the actual RRU serial number of the current site.

[0147] S704, click Submit;

[0148] For example, after obtaining the actual RRU serial number of the current site, the front-end operator can click Submit to synchronize the actual RRU serial number of the current site to the back-end.

[0149] S705: Receive the RRU matching detection result.

[0150] Exemplarily, the backend may perform a matching test on the RRU serial number and feed back the test result to the frontend, and the frontend operator receives the RRU matching test result.

[0151] During the above operation process of Example 2, the front-end operator only needs to perform simple scanning and recognition to obtain the results through automatic matching of the tool. The operation method is simple and the skill requirements for the operator are low.
