Abstract
Description
Technical Field
[0001] This application relates to the field of wireless communication technology, and in particular to an IMT ground station parameter adjustment method, apparatus and related equipment. Background Technology
[0002] With the deepening international coordination of IMT ground station deployments and the ongoing border radio management efforts, ensuring that the signal strength declared by border stations meets the limits of international bilateral agreements has become a crucial issue for safeguarding radio spectrum resources and preventing cross-border interference. Current technologies can only determine the compliance of IMT ground station deployments; if limits are exceeded, they cannot pinpoint which stations are responsible from the lumped field strength, nor can they provide a basis for subsequent adjustments.
[0003] Thus, since the lumped signal strength is the sum of signals from multiple stations, and the specific cause of exceeding the limit involves multiple factors, the cause of the exceedance cannot be determined. Therefore, we can only rely on manual experience for trial adjustments, which is not only inefficient, but also prone to causing undue impact on normal coverage due to mismatch between the adjustment methods and the cause of the exceedance, making it difficult to achieve compliant deployment efficiently and accurately. Summary of the Invention
[0004] This application provides an IMT ground station parameter adjustment method, apparatus, and related equipment, which, based on accurately locating the location of signal exceeding limits on the border line, objectively classifies and adapts differentiated adjustment strategies to achieve compliant deployment of border line signals with minimal network performance cost.
[0005] In a first aspect, embodiments of this application provide a method for adjusting IMT ground station parameters, the method comprising:
[0006] The lumped signal field strength of each sampling point on the target border is obtained. The lumped signal field strength of a sampling point is the total field strength of the radio signals transmitted by all IMT ground stations received at that sampling point.
[0007] If the lumped signal field strength of any first sampling point on the aforementioned target border line exceeds the limit of the international bilateral agreement corresponding to the aforementioned first sampling point, then the aforementioned first sampling point will be determined as an over-limit sampling point.
[0008] Based on the individual signal field strength of each IMT ground station relative to the above-mentioned over-limit sampling point, the distance of each IMT ground station to the above-mentioned over-limit sampling point, and the antenna gain of each IMT ground station relative to the above-mentioned over-limit sampling point, the station adjustment category to which each IMT ground station belongs is determined, and the adjustment strategies corresponding to different station adjustment categories are different.
[0009] Based on the adjustment strategy corresponding to each station's adjustment category, the parameters of the corresponding IMT ground stations are adjusted respectively.
[0010] The technical solution provided in this application brings at least the following beneficial effects:
[0011] The embodiments of this application obtain the lumped signal field strength of the sampling points along the border and accurately locate the over-limit position. Then, based on the multi-dimensional attributes of each station, a differentiated adjustment strategy is matched, which effectively solves the problem of blind and inefficient network adjustment caused by the lack of targeted adjustment basis in the prior art. Specifically, firstly, by acquiring the lumped signal strength of each sampling point along the target border and comparing it with the limits set by international bilateral agreements, the excess sampling points were accurately located, providing a clear target for subsequent adjustments. Based on this, after pinpointing the excess locations, data from each IMT ground station in three dimensions—signal strength, distance, and antenna gain—were further introduced to comprehensively diagnose the causes of the excess from three aspects: signal contribution, spatial propagation loss, and antenna directivity. This avoided the deficiency of being unable to locate the responsible station based solely on lumped results. Subsequently, based on the aforementioned multi-dimensional diagnostic results, each station was classified into different adjustment categories, and corresponding differentiated adjustment strategies were matched for each category to ensure that the adjustment methods accurately corresponded to the causes of the excess. Finally, the parameters of the corresponding stations were adjusted according to their respective matched strategies. This accurately resolved the border signal excess problem while minimizing excessive interference with the normal coverage services of the stations, achieving the technical effect of compliant deployment with minimal network performance cost.
[0012] One possible implementation involves determining the station adjustment category of each IMT ground station based on the individual signal strength of each IMT ground station relative to the over-limit sampling point, the distance from each IMT ground station to the over-limit sampling point, and the antenna gain of each IMT ground station relative to the over-limit sampling point, including:
[0013] Based on the individual signal strengths mentioned above, the IMT ground stations among the IMT ground stations whose contribution to the total signal strength meets the preset high contribution condition are identified as high contribution IMT ground stations.
[0014] The IMT ground stations are sorted from near to far according to their distance from the over-limit sampling points, and the first proportion of high-contribution IMT ground stations at the top of the sort are taken as the set of near-distance stations.
[0015] The IMT ground stations are sorted from largest to smallest relative to the over-limit sampling points, and the top two proportions of high-contribution IMT ground stations are taken as the opposing station set.
[0016] Based on the affiliation relationships between each of the aforementioned IMT ground stations and the aforementioned near-field station set and the aforementioned opposing station set, the station adjustment category to which each of the aforementioned IMT ground stations belongs is determined.
[0017] Another possible implementation involves identifying high-contribution IMT ground stations as those whose contribution to the lumped signal strength meets a preset high-contribution condition based on the individual signal strengths. This includes:

[0019] According to the above order of individual signal field strength from high to low, the individual signal field strength that ranks first is determined to be the strongest individual signal field strength.
[0020] IMT ground stations whose difference between the above-mentioned individual signal field strength and the above-mentioned strongest individual signal field strength is less than a preset field strength difference are identified as the above-mentioned high-contribution IMT ground stations.
[0021] Another possible implementation involves determining the station adjustment category of each IMT ground station based on its affiliation with both the nearby station set and the opposing station set, including:
[0022] IMT ground stations that belong to both the above-mentioned near-distance station set and the above-mentioned opposite station set are identified as Class I adjustment stations.
[0023] IMT ground stations that belong only to the above-mentioned set of nearby stations are classified as Category II adjustment stations.
[0024] IMT ground stations belonging solely to the aforementioned set of opposing stations are classified as Category III adjustment stations; and...
[0025] IMT ground stations that do not belong to the above-mentioned set of nearby stations and do not belong to the above-mentioned set of opposing stations are identified as Category IV adjustment stations.
[0026] Another possible implementation method, the adjustment strategy corresponding to the above-mentioned type of adjustment station includes: reducing the power of the IMT ground station according to the first power adjustment range;
[0027] The adjustment strategies corresponding to the above two types of adjustment stations include: reducing the power of IMT ground stations according to the second power adjustment range;

[0030] The first power adjustment range is greater than the second power adjustment range.
[0031] Another possible implementation involves adjusting the parameters of the corresponding IMT ground stations according to the adjustment strategy corresponding to each station's adjustment category, including:
[0032] According to the priority order of the above-mentioned Category I, Category II, and Category III adjustment stations, and based on the adjustment strategies corresponding to each of the above-mentioned Category I, Category II, and Category III adjustment stations, the parameters of the corresponding IMT ground stations are adjusted respectively.
[0033] The priority order is as follows: first reduce the power of the first type of adjustment station, then reduce the power of the second type of adjustment station, and finally reduce the antenna downtilt angle of the third type of adjustment station by a uniform amount.
[0034] Another possible implementation, after adjusting the parameters of the corresponding IMT ground stations according to the adjustment strategy corresponding to each station's adjustment category, also includes:
[0035] After adjusting the parameters of the IMT ground stations, the lumped signal strength of each sampling point is reacquired, and limit comparison is continued based on the reacquired lumped signal strength of each sampling point until the lumped signal strength of each sampling point meets the corresponding international bilateral agreement limit.

Different adjustment strategies correspond to different station adjustment categories.

[0078] The following section will describe in detail the IMT ground station parameter adjustment method, device, and related equipment provided in this application, with reference to the accompanying drawings.
[0079] The technical solutions of the embodiments of this application will be clearly described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application are within the scope of protection of this application.
[0080] The terms "first," "second," etc., used in the specification and claims of this application are used to distinguish similar objects and not to describe a specific order or sequence. It should be understood that such use of data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and the number of objects is not limited; for example, a first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.
[0081] The terms "at least one," "at least one of," etc., used in the specification and claims of this application refer to any one, any two, or a combination of two or more of the included items. For example, at least one of a, b, and c can mean: "a," "b," "c," "a and b," "a and c," "b and c," and "a, b, and c," where a, b, and c can be single or multiple. Similarly, "at least two" refers to two or more items, and its meaning is similar to that of "at least one."
[0082] In the description of this application, unless otherwise stated, "a plurality of" means two or more.
[0083] The present application provides an IMT ground station parameter adjustment method, apparatus, and related equipment, which can be applied to the scenario of radio frequency parameter compliance detection and automated adjustment of IMT ground stations in wireless communication networks.
[0084] Along land borders, IMT ground stations must declare their signal strength according to international bilateral agreements to protect spectrum usage rights. While existing technologies can simulate and calculate the lumped signal strength at border points and compare it to agreement limits to identify locations exceeding limits, this only provides detection and lacks automated adjustments for network deployments that do not meet the limits. In practice, relying on manual experience to make general adjustments to base stations is not only inefficient and difficult to converge, but also fails to differentiate the contributions of different base stations to points exceeding limits (e.g., near-range positive, sidelobe, or far-range positive). This can easily lead to over-adjustment at the expense of domestic network quality. Furthermore, the lack of a closed-loop iterative mechanism makes it impossible to ensure that all border points ultimately fully meet international agreement limits after adjustments.
[0085] To address the aforementioned technical problems, this application provides a method, apparatus, and related equipment for adjusting IMT ground station parameters. The method in this embodiment acquires the lumped signal field strength of sampling points along the border and accurately locates locations exceeding limits. Then, based on the multi-dimensional attributes of each station, it matches differentiated adjustment strategies, effectively solving the problems of blind and inefficient network adjustments caused by a lack of targeted adjustment criteria in existing technologies. Specifically, firstly, by acquiring the lumped signal strength of each sampling point along the target border and comparing it with the limits set by international bilateral agreements, the excess sampling points were accurately located, providing a clear target for subsequent adjustments. Based on this, after pinpointing the excess locations, data from each IMT ground station in three dimensions—signal strength, distance, and antenna gain—were further introduced to comprehensively diagnose the causes of the excess from three aspects: signal contribution, spatial propagation loss, and antenna directivity. This avoided the deficiency of being unable to locate the responsible station based solely on lumped results. Subsequently, based on the aforementioned multi-dimensional diagnostic results, each station was classified into different adjustment categories, and corresponding differentiated adjustment strategies were matched for each category to ensure that the adjustment methods accurately corresponded to the causes of the excess. Finally, the parameters of the corresponding stations were adjusted according to their respective matched strategies. This accurately resolved the border signal excess problem while minimizing excessive interference with the normal coverage services of the stations, achieving the technical effect of compliant deployment with minimal network performance cost.
[0086] The following description, in conjunction with the accompanying drawings, details the IMT ground station parameter adjustment method, apparatus, and related equipment provided in the embodiments of this application.
[0087] Figure 1 This illustration shows the network architecture of an IMT ground station parameter adjustment method provided in an embodiment of this application. For example... Figure 1 As shown, the network architecture includes an IMT ground station parameter adjustment device 101 and a terminal device 102. The IMT ground station parameter adjustment device 101 and the terminal device 102 are interconnected.
[0088] In some embodiments, the IMT ground station parameter adjustment device 101 may be a server, a computer, or a processor or processing unit within a server or computer. The server may be a single server or a server cluster consisting of multiple servers. It should be noted that this application does not limit the specific device form of the IMT ground station parameter adjustment device 101.

Figure 1 The example shown is a mobile phone, with terminal device 102 as an example.
[0090] In some embodiments, the IMT ground station parameter adjustment device 101 is used to acquire the lumped signal field strength of each sampling point on the target border, determine the sampling points exceeding the limit based on the comparison result between the lumped signal field strength and the international bilateral agreement limit corresponding to each sampling point, and determine the station adjustment category of each IMT ground station based on the individual signal field strength of each IMT ground station in the direction pointing to the sampling point exceeding the limit, the distance of each IMT ground station to the sampling point exceeding the limit, and the antenna gain of each IMT ground station in the direction pointing to the sampling point exceeding the limit, and adjust the parameters of the corresponding IMT ground station according to the adjustment strategy corresponding to each station adjustment category; the terminal device 102 is used to send configuration instructions to the IMT ground station parameter adjustment device 101, and / or receive and display the adjustment scheme generated by the IMT ground station parameter adjustment device 101.
[0091] It should be noted that the network architecture described in the embodiments of this application is for the purpose of more clearly illustrating the technical solutions of the embodiments of this application, and does not constitute a limitation on the technical solutions provided in the embodiments of this application. As network architectures evolve, the technical solutions provided in the embodiments of this application are also applicable to similar technical problems.
[0092] See Figure 2This is a flowchart illustrating a method for adjusting IMT ground station parameters provided in an embodiment of this application. Figure 2 As shown, the IMT ground station parameter adjustment method provided in this application embodiment can be implemented by the above-mentioned IMT ground station parameter adjustment device, specifically including the following steps 201 to 204.
[0093] Step 201: The IMT ground station parameter adjustment device obtains the lumped signal field strength of each sampling point on the target border. The lumped signal field strength of a sampling point is the total field strength of the radio signals transmitted by all IMT ground stations received at that sampling point.
[0094] Step 202: If the lumped signal field strength of any first sampling point on the target border line exceeds the limit of the international bilateral agreement corresponding to the first sampling point, the IMT ground station parameter adjustment device will determine the first sampling point as the sampling point exceeding the limit.
[0095] Step 203: The IMT ground station parameter adjustment device determines the station adjustment category of each IMT ground station based on the individual signal field strength of each IMT ground station relative to the over-limit sampling point, the distance of each IMT ground station to the over-limit sampling point, and the antenna gain of each IMT ground station relative to the over-limit sampling point. Different adjustment strategies correspond to different station adjustment categories.
[0096] Step 204: The IMT ground station parameter adjustment device adjusts the parameters of the corresponding IMT ground stations according to the adjustment strategy corresponding to each station adjustment category.
[0097] First, the IMT ground station parameter adjustment device acquires the lumped signal field strength of each sampling point on the target border. In this embodiment, the lumped signal field strength of a sampling point is the total field strength obtained by superimposing the radio signals transmitted by all IMT ground stations received at that sampling point.
[0098] In this embodiment, the target border line refers to the border segment requiring compliance assessment for international station declaration. In practical applications, multiple sampling points can be set at certain intervals along the target border line, and each sampling point can be understood as a signal receiving location located on the border line. The lumped signal field strength refers to the total field strength value formed by the superposition of all radio signals transmitted by IMT ground stations received at a certain sampling point. In other words, the lumped signal field strength of a sampling point comprehensively considers the signal contributions of all IMT ground stations around that sampling point to that sampling point, and is the result of the superposition of the individual signal field strengths of each IMT ground station.
[0099] Specifically, the lumped signal strength at each sampling point can be calculated based on parameters such as the transmit power, antenna gain, and propagation path loss of each IMT ground station. For example, the path loss from each IMT ground station to each sampling point can be calculated using the International Telecommunication Union (ITU) border coordination model (such as ITU-R Recommendation P.1546). The individual signal strength of each IMT ground station at each sampling point can then be calculated by combining the transmit power and antenna gain of the IMT ground station. Finally, the individual signal strengths of all IMT ground stations at the same sampling point are superimposed to obtain the lumped signal strength of that sampling point.
[0100] It should be noted that, for the specific calculation method of the lumped signal field strength, those skilled in the art can use any known signal field strength calculation method to obtain the lumped signal field strength of each sampling point, and this application does not limit it in this regard.
[0101] In this embodiment, by acquiring the lumped signal field strength at each sampling point, a data basis can be provided for subsequent determination of which sampling points exhibit exceedance phenomena. The lumped signal field strength reflects the overall intensity of the IMT ground station signal radiation received at each sampling point; therefore, the compliance of international station declarations can be determined based on the lumped signal field strength.
[0102] After obtaining the lumped signal field strength at each sampling point along the target border, the sampling points exceeding the limits can be determined based on the international bilateral agreement limits. Specifically, if the lumped signal field strength at any first sampling point along the target border exceeds the international bilateral agreement limit corresponding to the first sampling point, the IMT ground station parameter adjustment device will determine the first sampling point as an sampling point exceeding the limits.
[0103] In this embodiment, the international bilateral agreement limit refers to the upper limit of IMT ground station signal field strength allowed at various locations along the border, determined through bilateral consultation between my country and its neighboring countries. The international bilateral agreement limits corresponding to different sampling points may be the same or may differ depending on the bilateral coordination area. The first sampling point is a general term for any sampling point to be judged on the target border line, and does not refer to a specific sampling point.
[0104] Specifically, the lumped signal field strength at each sampling point is compared with the limit set by the corresponding international bilateral agreement. If the lumped signal field strength at a sampling point exceeds the limit set by the international bilateral agreement, it indicates that the signal radiation intensity at that sampling point has exceeded the allowable range of the agreement, and the sampling point is identified as an over-limit sampling point. It is understood that there may be zero, one, or more over-limit sampling points on the target border. This application's embodiments aim to address scenarios where over-limit sampling points exist.
[0105] In this embodiment, by identifying the out-of-limit sampling points, the border locations of interest can be accurately located. By identifying the out-of-limit sampling points from all sampling points, unnecessary adjustments to areas where there are no out-of-limit issues can be avoided.
[0106] Subsequently, the IMT ground station parameter adjustment device determines the station adjustment category of each IMT ground station based on the individual signal field strength of each IMT ground station relative to the over-limit sampling point, the distance of each IMT ground station to the over-limit sampling point, and the antenna gain of each IMT ground station relative to the over-limit sampling point. Different adjustment strategies correspond to different station adjustment categories.
[0107] In this embodiment, the individual signal strength refers to the signal strength generated by a single IMT ground station at the over-limit sampling point, i.e., the contribution of the IMT ground station to the lumped signal strength of the over-limit sampling point. Distance refers to the spatial distance between the IMT ground station and the over-limit sampling point, i.e., the spatial proximity between the station and the over-limit sampling point. Antenna gain refers to the gain value of the IMT ground station's antenna in the direction towards the over-limit sampling point, i.e., the degree of focus of the station's antenna radiation pattern in that direction. A higher antenna gain indicates that the main lobe or strong radiation direction of the station's antenna is more towards the over-limit sampling point.
[0108] Specifically, for each sampling point exceeding the limit, three types of information are obtained for all IMT ground stations relative to that sampling point: signal strength, distance, and antenna gain. Then, these three types of information are combined to classify the stations.
[0109] Optionally, during classification, IMT ground stations that contribute significantly to exceeding limits (i.e., high-contribution IMT ground stations) can first be identified by individual signal strength. Then, the reasons for the high contribution of these high-contribution IMT ground stations can be further determined by two dimensions: distance and antenna gain. That is, is it due to close distance, direct antenna alignment, both, or neither? Based on the above method, each station is divided into different station adjustment categories, and each category represents a different cause of the station's high signal contribution to the exceeding sampling points.
[0110] It should be noted that different adjustment strategies correspond to different station adjustment categories. This is because high-contribution stations under different causal modes require different parameter adjustment methods to effectively and efficiently reduce their signal contribution to the sampling points exceeding the limit. For example, for stations with high contribution due to close proximity and directly facing antennas, reducing power may be the most direct and effective method; while for stations with high contribution due to directly facing antennas but being far away, adjusting the antenna downtilt angle may be a more economical method.
[0111] In this embodiment, the station adjustment category is determined based on three dimensions, which enables accurate diagnosis of the causes of station exceeding limits, allowing subsequent parameter adjustments to be "targeted," thus providing a reliable classification basis for formulating differentiated adjustment strategies.
[0112] Finally, the IMT ground station parameter adjustment device adjusts the parameters of the corresponding IMT ground stations according to the adjustment strategy corresponding to each station adjustment category.
[0113] In this embodiment, IMT ground station parameters refer to the configurable operating parameters of the IMT ground station, including but not limited to transmit power, antenna downtilt angle, and antenna azimuth angle. Adjustment strategy refers to the parameter adjustment method defined for a specific station adjustment category; different categories correspond to different adjustment strategies.
[0114] Specifically, after determining the adjustment category to which each IMT ground station belongs, an adjustment strategy matching that category is adopted to adjust the parameters of each IMT ground station within that category. For example, for one category of stations, the adjustment strategy might be to reduce transmit power; for another category, the strategy might be to reduce the antenna downtilt angle; and for yet another category, the strategy might be to independently optimize and adjust based on individual propagation anomalies. Parameter adjustments for each station can be performed simultaneously or sequentially according to a certain priority order.
[0115] In this embodiment, different adjustment strategies are used to match the parameter adjustment method with the causes of exceeding limits caused by IMT ground stations. This ensures both the effectiveness and economy of the adjustment, thereby minimizing the impact on network service quality while ensuring that network deployment meets the limits of international bilateral agreements.
[0116] Based on the above method, the IMT ground station parameter adjustment method of this application embodiment, compared with the prior art, can automatically classify each IMT ground station into different adjustment categories according to its contribution characteristics to the exceeding limits for sampling points, and adjust the station parameters separately using differentiated adjustment strategies that match the causes of each category. Since different stations have different causes of signal contribution to the exceeding limits sampling points, the multi-dimensional classification realizes the judgment of the cause of the exceeding limits, and formulates targeted adjustment strategies accordingly. This avoids the problems of over-optimization or under-optimization caused by uniform adjustment methods, and can ensure that the lumped signal field strength of all sampling points meets the international bilateral agreement limits while minimizing the impact on network services, thereby ensuring the compliance of international declarations for IMT ground stations.
[0117] The technical solution of this application will be further described in detail below with reference to the accompanying drawings and through multiple embodiments. It should be noted that each of the following embodiments is based on the overall method flow described in steps 201 to 204 above, and each embodiment elaborates on the key steps in the above method from different directions.
[0118] In some embodiments, the process of determining the station adjustment category to which each IMT ground station belongs is described in detail, that is, how to identify high-contribution stations that make a significant contribution to the signal of the over-limit sampling points from a large number of IMT ground stations, and provide a basis for subsequent classification.
[0119] See Figure 3 This is a schematic flowchart illustrating the method for determining the adjustment category of IMT ground stations provided in an embodiment of this application. Figure 3 As shown, determining the station adjustment category to which each IMT ground station belongs may include the following steps 301 to 304.
[0120] Step 301: Based on the individual signal field strength, the IMT ground station parameter adjustment device determines the IMT ground station whose contribution to the lumped signal field strength meets the preset high contribution condition as a high contribution IMT ground station.
[0121] Step 302: Sort each IMT ground station by distance from the sampling point exceeding the limit from near to far, and take the first proportion of high-contribution IMT ground stations as the near-distance station set.
[0122] Step 303: Sort each IMT ground station in descending order of antenna gain relative to the over-limit sampling point, and take the second highest proportion of high-contribution IMT ground stations as the opposing station set.
[0123] Step 304: The IMT ground station parameter adjustment device determines the station adjustment category of each IMT ground station based on the affiliation relationship between each IMT ground station and the nearby station set and the opposing station set.
[0124] First, based on the individual signal field strength, the IMT ground station parameter adjustment device determines the IMT ground stations whose contribution to the lumped signal field strength meets the preset high contribution condition as high contribution IMT ground stations.
[0125] In this embodiment, the preset high contribution condition can be used as a criterion to determine whether the contribution of an IMT ground station to the lumped signal strength of the over-limit sampling points is sufficiently large. Stations that meet this condition are identified as high-contribution IMT ground stations, meaning that the station makes a significant contribution to the signal strength of the over-limit sampling points.
[0126] Specifically, each IMT ground station has a unique signal strength value at the over-limit sampling point. The larger this value, the greater the station's contribution to the lumped signal strength at the over-limit sampling point. By setting preset high contribution criteria, stations with larger contributions can be selected from all IMT ground stations.
[0127] In this embodiment, by identifying high-contribution IMT ground stations, the scope of subsequent classification and adjustment can be narrowed, concentrating processing resources on stations that truly make a significant contribution to exceeding limits. In a typical network deployment, there may be dozens or even hundreds of IMT ground stations covering a certain area, but only a few of them typically contribute significantly to the signal at a particular exceeding-limit sampling point. By using high-contribution screening, the computational load of subsequent classification and adjustment can be effectively reduced, while avoiding unnecessary adjustments to stations with smaller contributions.
[0128] Subsequently, in order of distance from nearest to farthest, the IMT ground station parameter adjustment device selects the first proportion of IMT ground stations from the high-contribution IMT ground stations to form a set of nearby stations.
[0129] In this embodiment, the first ratio is a parameter used to select the number of nearby stations. The nearby station set is a collection of high-contribution IMT ground stations that are closest to the sampling point exceeding the limit.
[0130] Specifically, after identifying the high-contribution IMT ground stations, the distance from each high-contribution station to the over-limit sampling point is calculated. These high-contribution stations are then sorted from closest to furthest, and the top-ranked stations (within a first proportion) are selected to form a near-distance station set. In practical applications, the first proportion is a configurable parameter, such as 10%, 15%, or 20%. For example, if there are 20 high-contribution IMT ground stations and the first proportion is set to 10%, then the two stations closest to the over-limit sampling point are selected to form the near-distance station set. It can be understood that the stations in the near-distance station set are those that are close to the over-limit sampling point, have low propagation path loss, and therefore contribute significantly to the signal strength of the over-limit sampling point.
[0131] In addition, in descending order of antenna gain, the IMT ground station parameter adjustment device selects the second largest proportion of IMT ground stations from the high-contribution IMT ground stations to form a counter-station set.
[0132] In this embodiment, the second ratio is a parameter used to filter the number of opposing stations. The opposing station set is a collection of stations with the highest antenna gain among the high-contribution IMT ground stations.
[0133] Specifically, after identifying the high-contribution IMT ground stations, the antenna gain value of each high-contribution station relative to the direction of the over-limit sampling point is obtained. These high-contribution stations are then sorted from largest to smallest antenna gain, and the stations with the highest second-proportion ratio are selected to form the opposing station set. In practical applications, the second proportion is a configurable parameter, such as 10%, 15%, or 20%. For example, if there are 20 high-contribution IMT ground stations and the second proportion is set to 10%, then the two stations with the highest antenna gain are selected to form the opposing station set. It can be understood that the stations in the opposing station set are those whose antenna main lobe or strong radiation direction is towards the over-limit sampling point, have high antenna gain, and therefore contribute significantly to the signal strength of the over-limit sampling point.
[0134] It should be noted that the first and second ratios can be the same or different values, and can be flexibly set according to the characteristics of network deployment and adjustment needs. Stations in the nearby station set and the opposite station set may overlap; that is, a station may belong to both sets simultaneously, to only one set, or to neither set.
[0135] Finally, the IMT ground station parameter adjustment device determines the station adjustment category of each IMT ground station based on the affiliation relationship between each IMT ground station and the nearby station set and the opposing station set.
[0136] In this embodiment, for each high-contribution IMT ground station, it is determined whether it belongs to the near-field station set or the opposite station set. Based on different combinations of affiliation relationships, the station is classified into different station adjustment categories.
[0137] High-contribution stations are further screened using two dimensions: distance and antenna gain. This constructs sets of nearby stations and opposing stations, and determines the station adjustment category based on the station's affiliation to these sets. This allows for the classification of high-contribution stations based on the two main physical causes of high signal contribution: proximity and direct antenna alignment. The distance dimension characterizes the impact of propagation path loss—the closer the distance, the smaller the path loss and the higher the signal strength. The antenna gain dimension characterizes the impact of antenna radiation directivity—higher gain indicates that the antenna radiation is more concentrated in the direction of the exceeding sampling point. The cross-combination of these two dimensions allows for precise diagnosis of the specific reasons for exceeding the limit for each high-contribution station, facilitating the development of targeted adjustment strategies.
[0138] Compared to the existing approach of uniformly adjusting all stations based solely on signal strength, this application's embodiment narrows the adjustment range through high-contribution screening and diagnoses the causes of high-contribution stations using two dimensions: distance and antenna gain. This enables a refined analysis of the mechanism of stations exceeding their contribution limits, providing an accurate classification basis for the formulation of subsequent differentiated adjustment strategies. Consequently, it can effectively eliminate the problem of exceeding limits while minimizing excessive intervention in stations that require no or only minor adjustments.
[0139] In one optional embodiment, this application provides two methods for determining high-contribution IMT ground stations:
[0140] Method 1: Based on the individual signal field strength of each IMT ground station from high to low, the IMT ground stations in the top third proportion are identified as high-contribution IMT ground stations.
[0141] Specifically, all IMT ground stations are sorted from highest to lowest based on their individual signal strength relative to the over-limit sampling points. A certain percentage (the third percentage) of the top-ranked stations are selected as high-contribution IMT ground stations. In practical applications, the third percentage is a configurable parameter, such as 10%, 15%, or 20%. For example, if there are 100 IMT ground stations covering the area of the over-limit sampling points, and the third percentage is set to 10%, then the top 10 stations with the highest individual signal strength are identified as high-contribution IMT ground stations. This method is suitable for scenarios with a large number of stations where it is desirable to select key stations at a fixed percentage.
[0142] Method 2: According to the order of individual signal field strength of each IMT ground station from high to low, the individual signal field strength with the highest value is determined as the strongest individual signal field strength; IMT ground stations whose individual signal field strength is less than the difference between the strongest individual signal field strength and the preset field strength difference are determined as high contribution IMT ground stations.
[0143] Specifically, the process first identifies the maximum individual signal strength (i.e., the strongest individual signal strength) among all IMT ground stations. Then, it calculates the difference between the individual signal strength of each station and this strongest individual signal strength. Stations with a difference less than a preset difference value are identified as high-contribution IMT ground stations. In practical applications, the preset difference value is a configurable parameter, such as 3dB, 5dB, or 10dB. For example, if the strongest individual signal strength is 60dB (μV / m) and the preset difference value is set to 5dB, then stations with individual signal strengths above 55dB (μV / m) are identified as high-contribution IMT ground stations. This method uses the strongest signal strength as a benchmark and selects stations with strengths close to it, making it suitable for scenarios with uneven signal strength distribution where absolute difference in signal strength is desired as the selection criterion.
[0144] It should be noted that the above two methods are merely examples, and this application is not limited to them. Those skilled in the art can choose one of the methods according to the actual needs of the scenario, or combine the two methods for comprehensive judgment, or adopt other screening methods that can identify high-contribution stations. The specific values of the third ratio and the preset field strength difference can be flexibly set according to factors such as network scale, number of stations, and adjustment accuracy requirements.
[0145] In one optional embodiment, the process of determining the station adjustment category based on the attribution relationship, and the adjustment strategy corresponding to each station adjustment category, are described in detail. Specifically, this describes how to classify stations into four adjustment categories based on their attribution relationships with nearby station sets and opposing station sets, and what adjustment strategy is adopted for each adjustment category.
[0146] See Figure 4 This application provides a schematic diagram of IMT ground station classification. For example... Figure 4 As shown, based on the affiliation relationships between each IMT ground station and the nearby station set and the opposing station set, IMT ground stations can be divided into the following four categories of adjustment stations:
[0147] First, IMT ground stations that belong to both the nearby station set and the opposing station set are identified as a type of adjustment station.
[0148] One type of adjustment station is one that is both close to the over-limit sampling point and has a high antenna gain. The close proximity means low propagation path loss, and the high antenna gain means the antenna radiation direction is directly facing the over-limit sampling point. The combination of these two factors makes this type of station the most significant contributor to the signal strength at the over-limit sampling point, and is the primary factor causing the over-limit. Understandably, since the main lobe of the antenna of this type of adjustment station is directly facing the over-limit sampling point and is relatively close, its signal radiation intensity at the over-limit sampling point is much higher than that of other stations.
[0149] Second, IMT ground stations that belong only to the set of nearby stations are identified as Category II adjustment stations.
[0150] Type II adjustment stations are those located close to the over-limit sampling point but with low antenna gain. While the proximity results in lower propagation path loss, the main lobe of the antenna is not directly aligned with the over-limit sampling point; the over-limit sampling point is more within the radiation range of its sidelobes. Therefore, although Type II adjustment stations contribute significantly to the signal at the over-limit sampling point (due to proximity), the cause of this contribution differs from that of Type I adjustment stations, primarily due to distance rather than antenna orientation.
[0151] Third, IMT ground stations that belong only to the opposing station set are identified as Category III adjustment stations.
[0152] Category III adjustment stations are those with high antenna gain but located far from the over-limit sampling point. The main lobe of the antenna of this type of station is directly facing the over-limit sampling point, but due to the long distance and large propagation path loss, although its contribution to the signal of the over-limit sampling point is not negligible due to the high antenna gain, its influence is relatively small compared to Category I and Category II adjustment stations.
[0153] Fourth, IMT ground stations that do not belong to the set of nearby stations or the set of opposing stations are identified as Category IV adjustment stations.
[0154] Category IV adjustment stations are high-contribution stations that are neither close to the target location nor have high antenna gain. Although these stations are selected as high-contribution IMT ground stations (i.e., their individual signal strength at the over-limit sampling points is high), their high contribution is not due to close proximity or direct antenna alignment. This situation usually indicates the presence of individual propagation anomalies at the station, such as a higher elevation leading to an abnormally larger signal propagation range, the station being near water causing enhanced signal propagation due to water reflection, or a unique radio propagation environment in the area. These individual factors allow the station to still produce a high signal contribution to the over-limit sampling points despite not being close to the target location and not having a directly aligned antenna.
[0155] After identifying the four categories of adjustment stations, different adjustment strategies were adopted for each category. (See also...) Figure 5 This is a flowchart illustrating the adjustment strategies for various types of stations provided in the embodiments of this application. The adjustment strategies corresponding to each adjustment category are as follows:
[0156] One type of adjustment strategy for ground stations includes reducing the power of IMT ground stations according to the first power adjustment range.
[0157] Because Class I tuning stations are close together and their antennas are directly facing each other, they are the primary cause of exceeding the limit. A significant reduction in their transmit power is needed to effectively lower the signal strength at the exceeding sampling points. Simultaneously, for Class I tuning stations, adjusting the antenna azimuth angle may shift the main lobe direction away from the exceeding sampling point, but this will also cause a shift in the station's coverage area, potentially worsening the signal strength at other critical boundary locations. Simply lowering the antenna downtilt angle has limited improvement for close-range stations. Therefore, reducing transmit power is the most direct and effective adjustment method for Class I tuning stations. The first power adjustment magnitude is a relatively large power reduction to ensure that the high signal contribution of Class I tuning stations can be significantly reduced.
[0158] The adjustment strategies for Category II adjustment stations include: reducing the power of IMT ground stations according to the second power adjustment range.
[0159] Category II adjustment stations are located close to each other, but their antennas are not directly facing each other. Their signal contribution to the over-limit sampling points mainly comes from the low propagation path loss caused by the close proximity. Since the sidelobes of the antennas of these stations point to the over-limit sampling points, the cell coverage area can be reduced by appropriately lowering the transmission power, thus reducing signal radiation to the over-limit sampling points. The second power adjustment amplitude is smaller than the first power adjustment amplitude because the signal contribution of Category II adjustment stations is lower than that of Category I adjustment stations, and the required power adjustment is correspondingly smaller. It can be understood that the first power adjustment amplitude is larger than the second power adjustment amplitude, reflecting the matching relationship between the adjustment intensity and the degree of over-limit contribution of the station.
[0160] The adjustment strategies corresponding to the three types of stations include: reducing the antenna downtilt angle of IMT ground stations.
[0161] For Category 3 adjustable stations, the antennas are directly facing each other but at a considerable distance. Their signal contribution primarily comes from the antenna's main lobe pointing towards the over-limit sampling point. For these stations, lowering the antenna downtilt angle can deflect the antenna's main lobe downwards, thereby reducing the radiation intensity towards the over-limit sampling point. Compared to reducing power, lowering the antenna downtilt angle has a smaller impact on the station's normal coverage service because downtilt adjustment mainly affects coverage in long-distance areas, with limited impact on near-to-mid-distance coverage. Furthermore, since Category 3 adjustable stations are relatively far apart, lowering the downtilt angle can appropriately reduce signal radiation to the over-limit sampling point without excessively affecting station service. It should be noted that the downtilt range for Category 3 adjustable stations can be uniform, and each Category 3 adjustable station is only downtilted once per adjustment round to ensure that more distant stations can maintain normal service.
[0162] The adjustment strategies for the four types of adjustment stations include: independently optimizing and adjusting the IMT ground station based on individual propagation anomalies.
[0163] The signal contribution of the four types of stations is caused by individual propagation anomalies, which vary from station to station and cannot be resolved by a uniform adjustment strategy. For example, for stations with propagation anomalies due to excessively high altitude, it may be necessary to adjust the antenna height or add obstruction measures; for stations with propagation anomalies due to water surface reflection, it may be necessary to adjust the antenna azimuth angle to avoid the reflection path; for stations with anomalies due to special radio propagation environments, it may be necessary to comprehensively adjust multiple parameters such as power, downtilt angle, and azimuth angle. Therefore, the four types of stations need to be independently optimized and adjusted according to their specific individual propagation anomalies, and the adjustment method and adjustment range depend on the specific circumstances.
[0164] Regarding the order of adjustment, the parameters of the corresponding IMT ground stations are adjusted according to the priority order of Category I, Category II, and Category III adjustment stations, based on the adjustment strategies corresponding to each type of adjustment station. Specifically, the priority order is as follows: first reduce the power of Category I adjustment stations, then reduce the power of Category II adjustment stations, and finally reduce the antenna downtilt angle of Category III adjustment stations by a uniform amount.
[0165] In this embodiment, the first type of adjustment stations contributes the most to reducing the over-limit signal strength. Prioritizing the adjustment of the first type of stations can reduce the lumped signal strength of the over-limit sampling points as quickly as possible, achieving the greatest improvement effect at the most critical stage. The second type of adjustment stations contributes the second most. Adjusting the second type of stations after the adjustment of the first type of stations can further reduce the signal strength of the over-limit sampling points. The third type of adjustment stations contributes relatively little, and their adjustment method (lowering the tilt angle) has a relatively mild effect. Adjusting them last can supplement and optimize the adjustments made by the first two types of stations. The fourth type of adjustment stations, since their adjustment needs to be carried out independently based on individual factors, can be handled during or after the adjustment of the above three types of stations, depending on the specific situation.
[0166] Regarding the specific calculation of the power adjustment range, the power adjustment range for Category I and Category II adjustment stations can be determined based on the difference between the current lumped signal field strength of the out-of-limit sampling point and the target limit. For example, the power adjustment range can be calculated as follows: based on the difference between the lumped signal field strength of the out-of-limit sampling point and the target limit, multiply by a certain margin ratio (e.g., 20%), divide by the number of stations requiring adjustment under that category, and finally perform linearization to obtain the power adjustment range for each station. A smaller margin ratio results in a result closer to the limit after adjustment and higher accuracy, but may require more iterations; a larger margin ratio results in a larger adjustment range per iteration and higher processing efficiency, but may lead to a greater deviation between the adjusted result and the limit. Since the number of Category I adjustment stations is usually smaller, the power adjustment range allocated to each station is larger (i.e., the first power adjustment range is larger); the number of Category II adjustment stations is relatively larger, and the power adjustment range allocated to each station is relatively smaller (i.e., the second power adjustment range is smaller).
[0167] In this embodiment, the station is divided into four categories and equipped with differentiated adjustment strategies, which enables each type of station to match the corresponding adjustment strategy, accurately solve various causes of exceeding limits, and make the adjustment efficient. Secondly, the adjustment range matches the signal contribution size, which can prevent excessive adjustment from affecting network services. Finally, the adjustment is carried out in order of priority according to the first, second and third categories, and the main interference sources are dealt with first, which can reduce the adjustment iteration operation.
[0168] In one optional embodiment, the processing procedure following the adjustment of the station parameters is described in detail. Specifically, it describes how to verify the adjustment effect after adjusting the station parameters and how to ensure that all sampling points meet the limit requirements through iterative processing.
[0169] See Figure 6 This is a flowchart illustrating an iterative adjustment method provided in an embodiment of this application. Figure 6 As shown, after adjusting the parameters of the corresponding IMT ground stations according to the adjustment strategies corresponding to each station adjustment category, the method further includes the following steps 601 and 602.
[0170] Step 601: After adjusting the parameters of the IMT ground station, the IMT ground station parameter adjustment device reacquires the lumped signal field strength of each sampling point.
[0171] In this embodiment, after adjusting the parameters of the IMT ground stations, the individual signal strength of each IMT ground station at each sampling point will change, which in turn will cause the lumped signal strength at each sampling point to change. Therefore, it is necessary to recalculate the lumped signal strength at each sampling point based on the adjusted station parameters. The method of re-acquiring the signal strength is the same as that of acquiring the lumped signal strength in step 201, the only difference being that the station parameters used are the adjusted parameters.
[0172] Step 602: The IMT ground station parameter adjustment device continues to compare the limit values based on the lumped signal field strength of each sampling point that has been reacquired, until the lumped signal field strength of each sampling point meets the corresponding international bilateral agreement limit.
[0173] In this embodiment, the lumped signal strength of each newly acquired sampling point is compared again with its corresponding international bilateral agreement limit to determine whether there are still sampling points exceeding the limit. If the lumped signal strength of all sampling points meets the corresponding international bilateral agreement limit, it indicates that the current network deployment meets the international station reporting rules, and the adjustment process ends. If there are still sampling points exceeding the limit, the process described in steps 202 to 204 above is repeated for those sampling points. This process is iterated until the lumped signal strength of all sampling points meets the corresponding international bilateral agreement limit.
[0174] In this embodiment of the application, since a single parameter adjustment may not be able to make all sampling points meet the limit at once (for example, reducing the power of a certain station may solve the problem of one sampling point exceeding the limit, but due to the complexity of network deployment, it is difficult to accurately predict the field strength changes of other sampling points), the iterative adjustment mechanism can gradually approach and finally achieve the goal of all sampling points meeting the limit through multiple rounds of adjustment.
[0175] To make the technical solution of this application clearer and more intuitive, a specific application scenario embodiment is described below.
[0176] In this embodiment, a land border is used as an example. Multiple IMT ground stations are deployed along this border, and the neighboring countries on both sides of the border have signed bilateral agreements specifying signal strength limits at various locations along the border (for example, a limit of 40 dB(μV / m) for signal strength E). An international station declaration compliance assessment and adjustment are now required for the deployment of IMT ground stations along this border.
[0177] First, sampling points were set up at regular intervals (e.g., 1 km) along the target border, for a total of 100 sampling points. The lumped signal strength of all IMT ground stations at each sampling point was obtained. Calculations showed that the lumped signal strengths of sampling points 35, 36, and 37 were 43 dB (μV / m), 45 dB (μV / m), and 42 dB (μV / m), respectively, all exceeding the 40 dB (μV / m) limit. Therefore, these three sampling points were identified as exceeding the limit.
[0178] Taking sampling point 36 (lumped signal strength 45dB (μV / m), exceeding the limit by 5dB) as an example, this will be explained. There are 50 IMT ground stations covering the area where this sampling point is located. First, the individual signal strength of each of these 50 stations at sampling point 36 is calculated and sorted from highest to lowest. Method 1 (with the third proportion set at 10%) is used to screen high-contribution stations, and the top 5 stations with the highest individual signal strength are selected as high-contribution IMT ground stations.
[0179] Then, the distances from these five high-contribution stations to sampling point 36 are calculated, and the antenna gain of each station relative to sampling point 36 is obtained. Stations are sorted from closest to furthest distance, and the top 10% (one station) are selected to form a near-range station set; stations are sorted from largest to smallest antenna gain, and the top 10% (one station) are selected to form a facing station set. Assuming station A belongs to both the near-range and facing station sets, station A is classified as a Class I adjustment station; station B belongs only to the near-range station set and is classified as a Class II adjustment station; station C belongs only to the facing station set and is classified as a Class III adjustment station; stations D and E belong to neither the near-range nor the facing station set and are classified as Class IV adjustment stations.
[0180] Next, adjustments are performed according to priority: First, the transmit power of station A (a Class I adjustment station) is reduced by the first power adjustment magnitude, which is calculated by multiplying the difference between the current lumped signal strength at sampling point 36 and the limit (5dB) by a 20% margin and dividing by the number of Class I adjustment stations (1). Then, the transmit power of station B (a Class II adjustment station) is reduced by the second power adjustment magnitude, which is smaller than the first power adjustment magnitude. Finally, the antenna downtilt angle of station C (a Class III adjustment station) is reduced by a uniform magnitude. Stations D and E (Class IV adjustment stations) are independently optimized and adjusted based on their individual propagation anomalies (e.g., station D is at a higher elevation, and station E is near the water surface).
[0181] Similar analysis and adjustment procedures were performed on sampling points No. 35 and No. 37 that exceeded the limit. After adjusting the parameters of all stations related to the sampling points that exceeded the limit, the lumped signal field strength of all 100 sampling points was recalculated and compared with the limit of 40 dB (μV / m). If all sampling points met the limit, the adjustment was completed; if there were still sampling points that exceeded the limit, the next round of adjustment was performed on the sampling points that still exceeded the limit until all sampling points met the limit.
[0182] Through the above process, the lumped signal field strength of all sampling points along the border ultimately met the limits of the international bilateral agreement, the deployment of IMT ground stations met the international station declaration rules, and due to the adoption of a differentiated adjustment strategy, the impact on network services was controlled to a minimum.
[0183] In the above embodiments, the specific values of parameters such as the preset high contribution condition (e.g., the third ratio, the preset field strength difference), the first ratio, the second ratio, and the margin ratio are all configurable parameters. They can be flexibly set according to factors such as the actual network scale, the number of stations, the adjustment accuracy requirements, and the processing efficiency requirements. The specific values given in the above embodiments are only examples and do not constitute a limitation on the scope of protection of this application.
[0184] It should be noted that the above-described method embodiments, or the various possible implementations of the method embodiments, can be executed individually, or, provided there is no conflict, they can be combined with each other. The specific implementation can be determined according to actual usage requirements, and this application embodiment does not impose any restrictions on this.
[0185] As can be seen, the above mainly describes the solutions provided by the embodiments of this application from a methodological perspective. To achieve the above functions, the embodiments of this application provide corresponding hardware structures and / or software modules for executing each function. Those skilled in the art should readily recognize that, in conjunction with the modules and algorithm steps of the various examples described in the embodiments disclosed herein, the embodiments of this application can be implemented in hardware or a combination of hardware and computer software. Whether a function is executed in hardware or by computer software driving hardware depends on the specific application and design constraints of the technical solution. Those skilled in the art can use different methods to implement the described functions for each specific application, but such implementation should not be considered beyond the scope of this application.
[0186] This application embodiment can divide the IMT ground station parameter adjustment device into functional modules according to the above method example. For example, each function can be divided into a separate functional module, or two or more functions can be integrated into one processing module. The integrated module can be implemented in hardware or as a software functional module. Optionally, the module division in this application embodiment is illustrative and only represents one logical functional division; other division methods may be used in actual implementation.
[0187] In some embodiments, this application also provides an IMT ground station parameter adjustment device. This IMT ground station parameter adjustment device may include one or more functional modules for implementing the IMT ground station parameter adjustment method of the above method embodiments.
[0188] For example, Figure 7 This is a schematic diagram of the structure of an IMT ground station parameter adjustment device provided in an embodiment of this application. Figure 7 As shown, the IMT ground station parameter adjustment device 700 includes: an acquisition module 701, a determination module 702, and an adjustment module 703.
[0189] The acquisition module 701 is used to acquire the lumped signal field strength of each sampling point on the target border. The lumped signal field strength of a sampling point is the total field strength of the radio signals transmitted by all IMT ground stations received at that sampling point.
[0190] The determination module 702 is used to determine the first sampling point as an over-limit sampling point if the lumped signal field strength of any first sampling point on the target border line exceeds the limit of the international bilateral agreement corresponding to the first sampling point.
[0191] The determination module 702 is also used to determine the station adjustment category of each IMT ground station based on the individual signal field strength of each IMT ground station relative to the over-limit sampling point, the distance of each IMT ground station to the over-limit sampling point, and the antenna gain of each IMT ground station relative to the over-limit sampling point. Different adjustment strategies are corresponding to different station adjustment categories.
[0192] The adjustment module 703 is used to adjust the parameters of the corresponding IMT ground stations based on the adjustment strategy corresponding to each station's adjustment category.
[0193] Based on the above method, the IMT ground station parameter adjustment method of this application embodiment, compared with the prior art, can automatically classify each IMT ground station into different adjustment categories according to its contribution characteristics to the exceeding limits for sampling points, and adjust the station parameters separately using differentiated adjustment strategies that match the causes of each category. Since different stations have different causes of signal contribution to the exceeding limits sampling points, the multi-dimensional classification realizes the judgment of the cause of the exceeding limits, and formulates targeted adjustment strategies accordingly. This avoids the problems of over-optimization or under-optimization caused by uniform adjustment methods, and can ensure that the lumped signal field strength of all sampling points meets the international bilateral agreement limits while minimizing the impact on network services, thereby ensuring the compliance of international declarations for IMT ground stations.
[0194] In some embodiments, the determining module 702 is specifically used for:
[0195] Based on the individual signal field strength, the IMT ground stations whose contribution to the lumped signal field strength meets the preset high contribution condition are identified as high contribution IMT ground stations.
[0196] Sort each IMT ground station by distance from the sampling point exceeding the limit from near to far, and take the first proportion of high-contribution IMT ground stations as the set of near stations.
[0197] Sort each IMT ground station by antenna gain relative to the over-limit sampling point from largest to smallest, and take the second largest proportion of high-contribution IMT ground stations as the opposing station set.
[0198] Based on the affiliation of each IMT ground station with the nearby station set and the opposing station set, the station adjustment category to which each IMT ground station belongs is determined.
[0199] In other embodiments, the determining module 702 is specifically used for:
[0200] Based on the order of individual signal field strength from high to low, the IMT ground stations in the top third proportion are identified as high-contribution IMT ground stations; or,
[0201] According to the order of individual signal field strength from high to low, the individual signal field strength that ranks first is determined as the strongest individual signal field strength.
[0202] IMT ground stations whose individual signal field strength is less than the difference between the strongest individual signal field strength and a preset field strength difference are identified as high-contribution IMT ground stations.
[0203] In some other embodiments, the determining module 702 is specifically used for:
[0204] IMT ground stations that belong to both the nearby station set and the opposing station set are classified as Class I adjustment stations.
[0205] IMT ground stations that belong only to the set of nearby stations are classified as Category II adjustment stations;
[0206] IMT ground stations belonging solely to the opposing station set are classified as Category III adjustment stations; and...
[0207] IMT ground stations that do not belong to the set of nearby stations or the set of opposing stations are classified as Category IV adjustment stations.
[0208] In some other embodiments, the adjustment strategy for a type of adjustment station includes: reducing the power of the IMT ground station according to a first power adjustment range;
[0209] The adjustment strategies for Category II adjustment stations include: reducing the power of IMT ground stations according to the second power adjustment range;
[0210] The adjustment strategies corresponding to the three types of stations include: reducing the antenna downtilt angle of IMT ground stations;
[0211] The adjustment strategies corresponding to the four types of adjustment stations include: independently optimizing and adjusting IMT ground stations based on individual propagation anomalies;
[0212] The first power adjustment range is greater than the second power adjustment range.
[0213] In some other embodiments, the adjustment module 703 is specifically used for:
[0214] According to the priority order of Category I, Category II, and Category III adjustment stations, and based on the adjustment strategies corresponding to each of the Category I, Category II, and Category III adjustment stations, the parameters of the corresponding IMT ground stations are adjusted respectively.
[0215] The priority order is as follows: first reduce the power of Category 1 adjustment stations, then reduce the power of Category 2 adjustment stations, and finally reduce the antenna downtilt angle of Category 3 adjustment stations by a uniform amount.
[0216] In some other embodiments, the acquisition module 701 is further configured to:
[0217] After adjusting the parameters of the IMT ground stations, the lumped signal strength of each sampling point is reacquired, and limit comparisons are continued based on the reacquired lumped signal strength of each sampling point until the lumped signal strength of each sampling point meets the corresponding international bilateral agreement limit.
