[0034] It should be noted that the terms "first," "second," etc., used in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of this disclosure described herein can be implemented in orders other than those illustrated or described herein. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this disclosure. Rather, they are merely examples of apparatuses and methods consistent with some aspects of the embodiments of this application as detailed in the appended claims.

[0035] It should also be understood that the term "including" indicates the presence of the described feature, whole, step, operation, element and / or component, but does not exclude the presence or addition of one or more other features, wholes, steps, operations, elements and / or components.

[0036] With the increasing prevalence of complex indoor wireless scenarios such as high-rise buildings, subway lines, large stadiums, airports, and high-speed rail stations, indoor distributed antenna systems (DAS) face significant limitations in cabling, construction, property management, and equipment storage space, resulting in weak coverage areas. Furthermore, there is still no ideal solution for monitoring the coverage of indoor DAS antennas; professional on-site testing and location verification, or user complaints, are required to pinpoint the areas with insufficient coverage.

[0037] Therefore, in this embodiment of the application, the measurement data based on outdoor base stations and indoor distributed antennas reported by the terminal and the weak coverage area discrimination model are combined with 5G digital indoor distributed precise positioning technology to perform algorithm calculations, determine the specific areas with insufficient coverage, and design a scheme to strengthen the areas with insufficient coverage.

[0039] For example, such as Figure 1 The diagram shown is a structural schematic of a communication system provided in an embodiment of this application. The system may include multiple outdoor base stations, indoor distribution equipment, and terminal equipment. The terminal equipment is communicatively connected to both the outdoor base stations and the indoor distribution equipment.

Specifically, an outdoor base station can be any of the following: a small base station, a wireless access point, a transmission receive point (TRP), a transmission point (TP), or some other type of access node.

[0044] In one scenario, the server can be a single server, or it can be a server cluster consisting of multiple servers. In some implementations, the server cluster can also be a distributed cluster. This application does not limit the specific implementation method of the server.

[0047] For example, such as Figure 2 The diagram shown is a structural schematic of a weak coverage area determination device 200 provided in an embodiment of this application. The determination device 200 may include a processor 201, a communication interface 202, and a communication line 203.

[0065] like Figure 3 As shown, Figure 3 A flowchart illustrating a method for determining a weak coverage area provided in an embodiment of this application includes: S301 to S303.

[0066] S301. Acquire multiple measurement data reported by terminal devices within the target coverage area of ​​the target indoor antenna.

[0067] The target indoor antenna is one of multiple indoor antennas in the indoor distribution system, which can be... Figure 1 Indoor distribution equipment.

[0068] In one example, the determining device can divide the coverage area of ​​the target indoor antenna into multiple grids. The target coverage area is one of these grids. Specifically, see [reference needed]. Figure 4 The description of the embodiments is omitted here.

[0069] It should be noted that within an indoor antenna grid, only the signal output from one indoor antenna and the signal covered by other outdoor base stations can be received.

[0070] The measurement data includes data from the terminal equipment measuring the signal of the target indoor distributed antenna and data from measuring the signals of multiple outdoor base stations. The outdoor base stations can be... Figure 1 Indoor base stations. For example, measurement data may include one or more of the following: outdoor base station ID, outdoor base station cell ID, indoor antenna grid number, base station longitude and latitude, coverage strength and signal to interference plus noise ratio (SINR), and timing advance (TA).

[0071] Here, coverage field strength refers to the signal strength within the coverage area of ​​an outdoor base station, specifically the signal strength at a certain location within the coverage area of ​​the outdoor base station's wireless network. In this embodiment, coverage field strength represents the signal strength reported by the terminal.

[0072] Network quality refers to the ratio of the strength of the received useful signal to the strength of the received interference signal (noise and interference). In this embodiment, it refers to the network quality reported by the terminal within the coverage area.

[0073] Time advance (TA) represents the distance between a terminal and an outdoor base station. In mobile communication systems, because different terminals are at different distances from the outdoor base station, the transmission time of the wireless signal in the air also varies. The farther a user is from the outdoor base station, the longer it takes for the signal to reach the base station. Therefore, the outdoor base station sets different TA values ​​for terminals at different distances. The outdoor base station represents the distance between the terminal and the base station by setting a reasonable TA for each terminal. In a mobile communication system, when TA = 1, the distance between the terminal and the base station is 1 * 78.12 m = 78.12 m; when TA = 2, the distance is 2 * 78.12 m = 156.24 m. The TA value changes according to the location of the terminal, so the terminal can determine the distance between itself and the outdoor base station based on the TA value.

[0074] In one example, multiple measurement data reported by the terminal can be stored in a database, for example, in the form of a table. For example, the measurement data reported by the terminal stored in the database can be as shown in Table 1.

[0075] Table 1

[0076]

[0077]

[0078] It should be noted that the data in Table 1 is exemplary, and this application does not impose any specific limitations on the data in the table.

[0079] In one example, the set Q of all base station cells that can receive signals within the grid covered by the indoor distributed antenna can be represented as: Q = {Cell1, Cell2, Cell3, ..., Cell...} a For example, Cell1 base station cell can be 3xxxx1 in Table 1.

[0080] Indoor distributed antenna grid can be represented as: Cell a ={Grid1, Grid2, Grid3,…Grid b For example, the Grid1 grid can be the indoor antenna grid numbered 001 in Table 1.

[0081] Data set reported by terminals of the indoor distributed antenna grid. b It can be represented as:

[0082]

[0083] Among them, {Strength i} represents the set of signal coverage field strengths reported by multiple terminals received by the indoor distributed antenna grid, {Ta i} represents the set of distances from multiple terminals to the outdoor base station, {Sinr i} represents the set of signal quality data for the indoor distributed antenna grid.

[0084] S302. Based on multiple measurement data, determine whether there is weak coverage in the target coverage area.

[0085] The target coverage area is a coverage area among multiple coverage areas that meets preset conditions. The preset conditions include: the multiple measurement data of the coverage area include first measurement data, the number of first measurement data is greater than a preset number, and the coverage field strength in the first measurement data is less than a preset intensity.

[0086] Weak coverage areas refer to areas where there is a signal, but the signal strength is insufficient to guarantee that the network meets the requirements.

[0087] In one possible implementation, the weak coverage determination model determines the average coverage strength of the target coverage area based on multiple coverage strengths reported by terminals within the target coverage area. If the average coverage strength within the coverage area is less than a preset strength, the area is determined to be a weak coverage area.

[0088] Among them, the average coverage field strength reported by the target area It can be represented as:

[0089]

[0090] n∈[2,n],b∈[1,m].

[0091] Among them, Grid b For the grid division, Strength1~Strenqth n This represents the coverage field strength reported by multiple terminals within the grid.

[0092] It should be noted that the average coverage field strength can be determined based on the indoor distributed antenna and its coverage area.

[0093] Furthermore, the network management platform transmits the list of fault alarms for the target coverage area to the weak coverage determination model, which then identifies areas outside the corresponding areas in the fault alarm list as weak coverage areas.

[0094] Among them, the regions with average field strength less than the preset field strength and the regions without fault alarms can be represented as a set. Cell fault This represents the set of grid fault alarm lists extracted by the network management platform.

[0095] For example, a list of fault alarms can be shown in Table 2.

[0096] Table 2

[0097]

[0098]

[0099] It should be noted that the data in Table 2 is exemplary, and this application does not impose any specific limitations on the data in the table.

[0100] Furthermore, the weak coverage determination model acquires the number of first measurement data points within the target coverage area. If the number of first measurement data points is greater than a preset number, the target coverage area is designated as a weak coverage area. The first measurement data point is the number of times the terminal signal strength is reported.

[0101] The relationship between the number of reported first measurement data and the preset number can be expressed as follows:

[0102]

[0103] in, B represents the number of first measurement data reported for the grid. th Indicates the preset quantity, Cell b Indicates a base station cell, Grid c This indicates the grid division.

[0104] In one example, the multiple measurement data reported by the terminal and the conditions for determining the weak coverage area can be shown in Table 3:

[0105] Table 3

[0106]

[0107]

[0108] It should be noted that the data in Table 3 is exemplary, and this application does not impose any specific limitations on the data in the table.

[0109] S303. If the target coverage area has weak coverage, the first area in the target coverage area is determined based on the planar distance between the terminal device and multiple outdoor base stations.

[0110] The first area is a weak coverage area within the target coverage area, and the horizontal distance is the distance between the terminal and the outdoor base station in the horizontal direction.

[0111] In one possible implementation, the weak coverage determination model can calculate the spatial distance between the terminal device and the outdoor base station based on the time advance (TA), where the spatial distance is the straight-line path length between the terminal device and the outdoor base station. Then, based on the spatial distance and a first distance, the planar distance between the terminal device and multiple outdoor base stations is calculated. The first distance is the height between the outdoor base station and the plane where the indoor distributed antenna is located.

[0112] Specifically, the spatial distance d between the computing terminal device and the outdoor base station TA This can be expressed as Formula 1:

[0113] d TA =TA*78.12 Formula 1

[0114] Specifically, the planar distance D between the computing terminal device and multiple outdoor base stations c This can be expressed as Formula 2:

[0115]

[0116] Among them, H c H represents the vertical height between the outdoor base station and the plane where the indoor distributed antenna is located. c The height is the difference between the height of the outdoor base station and the height of the indoor distributed antenna.

[0117] Based on the planar distances between the terminal device and multiple outdoor base stations, the location of the terminal is determined, thereby identifying the first area within the target coverage area, i.e., the weak coverage area within the target coverage area. For example... Figure 7 As shown, D1, D2, and D3 are the distances between the terminal and each outdoor base station, respectively, and the intersection point F is the location of the terminal.

[0118] The relationship between the reported measurement data and the first region can be shown in Table 4.

[0119] Table 4

[0120]

[0121] It should be noted that the data in Table 4 is exemplary, and this application does not impose any specific limitations on the data in the table.

[0122] based on Figure 3 The proposed technical solution, based on multiple measurement data reported by terminal devices within the target coverage area and combined with precise positioning technology, determines the weak coverage area of ​​the indoor distributed antenna. This allows for a simple and quick determination of signal coverage issues. Compared to traditional methods, the proposed solution consumes less time, improves efficiency, and saves additional resources and costs.

[0123] In some embodiments, such as Figure 4As shown, the method may also include S401.

[0124] S401. Divide the coverage area of ​​the indoor distributed antenna into a grid.

[0125] In one example, the indoor distributed antenna is used as the dividing center point, according to n×n(m 2 The coverage area of ​​the indoor distributed antenna is divided into grids, and the grids are numbered. The division results can be shown in Table 5, including the name of the outdoor base station, the indoor distributed antenna connected to the outdoor base station, the grid number centered on one indoor distributed antenna, and the latitude and longitude range corresponding to each grid.

[0126] Table 5

[0127]

[0128] It should be noted that the data in Table 5 is exemplary, and this application does not impose specific limitations on the data in the table.

[0129] For example, the indoor distributed antenna 3xxxx1 can be divided into two antenna grids, numbered 001 and 002 respectively. The latitude and longitude of grid 001 are (113.x, 22.x), (113.x, 22.x), (113.x, 22.x), (113.x, 22.x), and the latitude and longitude of grid 002 are (113.x, 22.x), (113.x, 22.x), (113.x, 22.x), (113.x, 22.x).

[0130] It should be noted that this application does not specifically limit the area range of the divided indoor antenna grid, and different settings can be made according to the actual coverage area of ​​the indoor antenna.

[0131] based on Figure 4 The technical solution involves dividing the indoor distributed antenna grid into grid units to obtain data reported by terminals within the grid. The divided grid can better identify areas with insufficient coverage by combining the terminals.

[0136] based on Figure 5 The technical solution strengthens weak coverage areas by adjusting parameters such as indoor distributed antenna power, adding indoor antennas, and modifying indoor directional antennas. This improves indoor signal strength, solves problems of call congestion and interference, and better meets user experience.
