These drawings and the written description are not intended to limit the scope of the inventive concepts in any way, but to illustrate the concepts of the present application to those skilled in the art by reference to specific embodiments.
Detailed Description
Exemplary embodiments will be described in detail herein, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, the same numbers in different drawings are the same or similar elements unless otherwise indicated. The implementations described in the following exemplary examples are not representative of all implementations consistent with the present application. Rather, they are merely examples of apparatus and methods consistent with some aspects of the present application as detailed in the accompanying claims.
The reasonable position deployment of the base station can improve the network quality received by the access terminal in the network coverage area, and brings good network experience to the user. In the prior art, when base station positions are deployed in an area to be planned, the base station positions are typically deployed in a relatively large number of areas by predicting the number of access terminals in the area to be planned. Wherein, the number of the access terminals in the area to be planned is predicted by predicting the number of users in the area to be planned. Optionally, the number of users in the area to be planned can be predicted according to the ratio situation of the users of the operators; the number of users entering the area to be planned can also be predicted according to the motion trail of the access users of the existing base station in the area to be planned; the number of users in the area to be planned, the number of predicted users, etc. may be counted by the national statistical bureau, the jurisdictional administration, etc., and the number of predicted users may be predicted in a plurality of ways, which are not exemplified here.
However, in the method for deploying the base station position, only the number of the access terminals in the area to be planned is considered, but the perception condition of the access terminals to the network signals is ignored, when the network signals are interfered, the interference source can be a pseudo base station or other equipment with interference capability, and the network signals received by the access terminals are deteriorated; or, the network signal is blocked, the network signal is partially reflected by the influence of high-rise building glass near the base station, the network signal received by the access terminal is also degraded, and the like, and the network signal is interfered or blocked, so that a bad induction area is formed near the position of the access terminal. Therefore, the existing method for deploying the base station position can have more bad feel areas in the area to be planned, and cannot meet the communication quality requirements of users. Secondly, in order to compensate the network effect caused by the poor induction area, the operator needs to perform a series of maintenance on the poor induction area, such as adjusting the antenna angle, expanding the capacity of the cell, and the like, thereby causing the cost of manpower.
Aiming at the problems in the prior art, the application considers the perception condition of the access terminal on the network quality, and screens out each bad-sense access terminal according to the interaction state of the access terminal and the network signal of the existing base station. And then determining the position of the differential access terminal according to the deployment scene where each differential access terminal accesses the existing base station. And finally, clustering the position of the differential access terminal to determine a differential area, and deploying the position of the base station on the differential area. According to the method, the sensing condition of the access terminal on the network quality and the deployment scene of the existing base station are considered, and the base station position is deployed on the poor sense area of the access terminal sensing the network quality, so that the poor sense area in the area to be planned is reduced from the source, and the communication quality requirement of a user is met. Meanwhile, subsequent maintenance of the poor sense area by the operator is avoided, and labor cost of the operator is saved.

As shown in fig. 1, there are a plurality of existing base stations 101 in an area to be planned, and a base station deployment position 103 is determined on a bad sense area where each terminal 102 receives a bad network quality according to the network quality condition of each terminal 102 accessing each existing base station. The specific application scenario of the application is applicable to the deployment of the base station position, the base station of the deployment position can be an indoor base station, an outdoor base station, a macro base station, a micro base station, a distributed base station, a remote radio base station and the like, and it is understood that the method for determining the deployment position of the base station provided by the application includes, but is not limited to, the above application scenario, and the method provided by the application can be adopted as long as all the scenarios of base station position determination are involved.
The following describes the technical solutions of the present application and how the technical solutions of the present application solve the above technical problems in detail with specific embodiments. The following embodiments may be combined with each other, and the same or similar concepts or processes may not be described in detail in some embodiments. Embodiments of the present application will be described below with reference to the accompanying drawings.
As shown in fig. 2, fig. 2 is a flowchart of a method for determining a deployment location of a base station according to an embodiment of the present application. As shown in fig. 2, the method may include the steps of:
s201, historical interaction data between an existing base station and an access terminal in an area to be planned is obtained, wherein the historical interaction data comprises quality parameters of network signals received by the access terminal from the existing base station.
The implementation subject of the present application may be an operator network management system, such as a server. Before deploying the base station location, the operator first needs to determine the area to be planned for deploying the base station location. The determined source of the area to be planned may be an area where user complaints are relatively large, or may be an area determined by market development planning, which is not limited herein.
And determining the existing base station in the area to be planned, and acquiring historical interaction data of the existing base station and the terminal accessed to the existing base station, wherein the historical interaction data can be acquired through an operator data management background. Because the access terminal and the existing base station mainly comprise call service and internet surfing service when performing network service, the acquired historical interaction data can comprise call interaction data and internet surfing interaction data, wherein the interaction data also comprises quality parameters of a plurality of access terminals for receiving network signals from the existing base station, the network services performed by the access terminals are different, specific values of the quality parameters are different, and the quality parameters comprise, but are not limited to, signal strength, signal quality, time delay, page response time delay, average cartoon duration, instantaneous rate, reference signal receiving power, signal-to-interference-noise ratio, instantaneous rate and the like.
S202, screening out all differential access terminals with quality parameters lower than a preset threshold value from the access terminals in the area to be planned.
In the area to be planned, there may be a plurality of existing base stations, and the number of terminals accessing each of the existing base stations is also large, so that it is necessary to screen out the differential access terminals from the access terminals in the area to be planned. The access terminal includes, but is not limited to, a mobile terminal and an internet of things terminal, as long as the terminal device can perform communication and internet surfing. For example: the mobile terminal can be a smart phone, a notebook computer, a tablet personal computer and the like, and the Internet of things terminal can be an automobile-mounted intelligent terminal and the like.
In particular, the method comprises the steps of,
and determining the interaction state between the access terminal and the existing base station according to the acquired historical interaction data of the access terminal and the existing base station. The interaction state may have five states of "excellent perception, good perception, general perception, poor perception and poor perception", and may also have other states, which should not be taken as a limitation of the present application.
The implementation manner of determining the interaction state may be: and judging a threshold interval in which the quality parameter is positioned according to the quality parameter value in the call interaction data or the internet interaction data of the access terminal, wherein different threshold intervals correspond to unused interaction states, so that the interaction state between the access terminal and the existing base station is determined.
For example, when the access terminal a performs a call interaction service with an existing base station, the existing base station determines, according to quality parameters in the acquired call interaction data, for example, signal strength data, signal quality data, delay data, and the like, and a signal strength threshold, a signal quality threshold, a delay threshold, and the like stored in the existing base station:
when the signal strength value is in the [ a, b ] threshold value interval, the interaction state between the access terminal and the existing base station is indicated as 'perception optimal'; when the signal strength value is in the [ b, c ] threshold value interval, the interaction state between the access terminal and the existing base station is indicated to be 'good perception'; when the signal strength value is in the [ c, d ] threshold interval, the interaction state between the access terminal and the existing base station is indicated as 'perception general'; when the signal strength value is in the [ d, e ] threshold value interval, the interaction state between the access terminal and the existing base station is indicated as 'poor perception'; when the signal strength value is within the [ e, f ] threshold interval, the interaction state between the access terminal and the existing base station is indicated as 'perception difference'.
If the multiple quality parameters of the access terminal are all in the [ e, f ] threshold interval, the access terminal is a bad-sense access terminal.
In a corresponding manner,
for example, when the access terminal a performs the internet interaction service with the existing base station, the existing base station determines according to quality parameters in the acquired internet interaction data, such as a page response delay, an average katon duration, an instantaneous rate, and the like, and a page response delay threshold, an average katon duration threshold, an instantaneous rate threshold, and the like stored in the existing base station. The specific judging process is consistent with the method for judging that the access terminal belongs to the differential access terminal according to the call interaction data, and details are not repeated here.
It should be noted that, whether the access terminal performs a call service or an internet service with the existing base station, if the interaction state between the access terminal and the existing base station is determined to be "perceived difference" according to the interaction data of any one of the services, it is determined that the access terminal belongs to a differential access terminal, so that the differential access terminal is screened from all the access terminals in the area to be planned.
S203, determining the position of each differential access terminal according to the deployment scene of the existing base station currently accessed by each differential access terminal.
The main function of the base station is to provide wireless coverage, and the access terminal can only receive signals sent by the base station in the coverage range of the base station network signals. The strength of the base station network signal directly influences the quality of the base station network received by the access terminal, and the strength of the base station network signal is in important connection with the service scene of the base station.
When the scene where the existing base station is located is a wide field of view, the transmission of signals in the wireless communication environment is not affected because the electromagnetic waves of the signals are transmitted in a straight line, the signal strength is strong, and the network signal quality received by the access terminal is still good even if the access terminal is far away from the existing base station; when the existing base station is located in a scene of a surrounding tall building group, as the transmission of signals is blocked by the building, the signals are attenuated due to the blocking of the obstacle, the signal strength is weakened, and even if the access terminal is close to the existing base station, the network signal quality received by the access terminal is still poor. Therefore, in deploying the base station location, a deployment scenario of an existing base station needs to be considered.
And determining the deployment scene of the existing base station from the fixed parameters of the running state of the existing base station in the operator data management background. The deployment scenario may be divided into villages in cities, industrial parks, residences, universities, etc.
And determining the position of each differential access terminal according to the deployment scene of the existing base station currently accessed by each differential access terminal and the differential access terminal screened in the previous step.
S204, clustering the positions of the differential access terminals to obtain the differential area in the area to be planned.
Through the steps, the positions of all the differential access terminals in the area to be detected can be obtained, the clustering algorithm is used for carrying out clustering processing on the positions of the differential access terminals in the area to be detected, and the differential area is determined.
The method includes the steps of taking the positions of all the differential access terminals as sample data, clustering sample points by using a density clustering algorithm, and clustering the positions of the differential access terminals meeting preset conditions into a differential area, wherein the preset conditions can be limiting the number of the positions or limiting the distance between the positions.
Wherein, because the clustering algorithm is an unsupervised algorithm commonly applicable in the current machine learning field, the use of the algorithm is more conventional and does not belong to the research focus of the application, and specific reference can be made to related technical documents, and details are not repeated here
S205, in the differential area, determining the deployment position of the base station.
After the differential area in the area to be planned is determined through the steps, the base station position is deployed in the differential area.
In the above embodiment of the present application, by acquiring historical interaction data between an existing base station and an access terminal in an area to be planned, each differential access terminal with a quality parameter lower than a preset threshold is screened out according to the historical interaction data. And then determining the position of each differential access terminal according to the deployment scene of the existing base station currently accessed by each differential access terminal, clustering the position of each differential access terminal to obtain a differential area, and directly deploying the position of the base station on the differential area, thereby reducing the differential area existing in the area to be planned from the source and meeting the communication quality requirement of users. Meanwhile, subsequent maintenance of the poor sense area by the operator is avoided, and labor cost of the operator is saved.
Further, on the basis of the step S203 in the above embodiment, the present embodiment specifically describes a process of determining the location of each differential access terminal according to the deployment scenario of the existing base station currently accessed by each differential access terminal. As shown in fig. 3, fig. 3 is a flowchart of a method for determining a location of each differential access terminal according to an embodiment of the present application. As shown in fig. 3, the method may include the steps of:
S301, obtaining the signal coverage furthest distance corresponding to the deployment scene of the existing base station currently accessed by each differential access terminal.
And determining the furthest distance covered by the signal corresponding to each access terminal according to the deployment scene of the existing base station currently accessed by each access terminal.
Specifically, determining a specific numerical value of the furthest distance covered by the signal of the existing base station from the set of furthest distances covered by the signal according to the deployment scene corresponding to the existing base station. Different base station deployment scenes in the set correspond to different signal coverage furthest distances, and specific numerical values of the base station deployment scenes are obtained through empirical data.
For example, d= { D 1 ，D 2 ，D 3 ，...，D n And D represents a set of furthest distances covered by the signal, n represents an nth deployment scene where the existing base station is located, and Dn represents the furthest distance covered by the signal of the existing base station when the deployment scene where the existing base station is located is a village in a city if n represents the village in the city.
S302, determining a distance attenuation ratio according to the quality parameter values of the differential access terminals and the corresponding quality standard values.
The corresponding quality standard value is the quality standard value corresponding to the deployment scene of the existing base station currently accessed by the differential access terminal.
Specifically, the distance attenuation ratio is determined according to the call service quality parameter value, the call service quality standard value, the internet service quality parameter value and the internet service quality standard value of each differential access terminal.
The call quality parameter value and the internet service quality parameter value of each differential access terminal can be determined by the current reference signal receiving power, the signal interference noise ratio, the instantaneous speed and the like. The standard value of the call service quality and the standard value of the internet service quality can be obtained through standard reference signal receiving power, standard signal interference noise ratio, standard instantaneous rate and the like.
S303, determining the position of each differential access terminal according to the furthest distance covered by the signal corresponding to each differential access terminal and the distance attenuation proportion.
Specifically, the location of each differential access terminal is determined according to the following distance attenuation formula.
Wherein A represents the distance between the differential access terminal and the existing base station; w (W) n1 The deployment scene of the existing base station accessed for the differential access terminal is the nth deployment scene, and the weight of the conversation service interaction between the differential access terminal and the accessed existing base station; w (W) n2 The deployment scene of the existing base station accessed for the differential access terminal is the nth deployment scene, and the weight of the internet service interaction between the differential access terminal and the accessed existing base station is the weight of the internet service interaction; c (C) 1 A call quality of service parameter value for the differential access terminal; c (C) 2 A network access service quality parameter value for the differential access terminal; m is M 1 The standard value of the call service quality is the standard value; m is M 2 The standard value of the internet service quality is used; d (D) n The deployment scene of the existing base station which is accessed currently for the differential access terminal is the furthest distance of signal coverage in the nth deployment scene.
In the above formula，W n1 And W is n2 The weight can be determined from a weight set according to the deployment scene of the existing base station and the network service performed by the differential access terminal, wherein the network service comprises a call service and a surfing service, and the specific numerical value of the weight in the set is obtained empirically.
Exemplary, w= { W 11 ，W 12 }，{W 21 ，W 22 }，...，{W n1 ，W n2 }}，W 11 The deployment scene of the existing base station accessed by the differential access terminal is the 1 st deployment scene, and the weight of the interaction of the call service between the differential access terminal and the accessed existing base station is W 12 The deployment scene of the existing base station accessed by the differential access terminal is the 1 st deployment scene, and the weight of the interaction of the internet service between the differential access terminal and the accessed existing base station is W n1 The deployment scene of the existing base station accessed by the differential access terminal is the nth deployment scene, and the weight of the interaction of the call service between the differential access terminal and the accessed existing base station is W n2 The deployment scene of the existing base station accessed by the differential access terminal is the nth deployment scene, and the weight of the internet service interaction between the differential access terminal and the accessed existing base station is represented by n, wherein n represents the nth deployment scene of the existing base station. For example, if the existing base station deployment scenario accessed by the access terminal is village in city and the access terminal is performing call service, the weight determined from the weight set is W 11 。
C 1 =reference signal received power/optimal reference signal received power+sir/optimal sir+ … + instantaneous rate/optimal instantaneous rate.
The reference signal received power, the signal to interference and noise ratio, the instantaneous rate, and the like are quality parameters in the call interaction data when the differential access terminal performs the call service. C (C) 2 And C 1 And the same is true, and only the reference signal receiving power, the signal interference noise ratio, the instantaneous speed and the like are quality parameters in the internet surfing interactive data when the differential access terminal performs the internet surfing service.
Further, through step S303, the distance between each differential access terminal and the existing base station is obtained, and then the position of each differential access terminal is determined according to the azimuth angle and the longitude and latitude of the existing base station, where the azimuth angle and the longitude and latitude of the existing base station can be obtained through fixed parameters of the running state of the existing base station, the longitude and latitude information of the existing base station can be acquired through GPS technology, and specific acquisition modes can refer to related files, which are not described herein.
To facilitate an understanding of the above process, a process for determining the location of a differential access terminal is illustrated: assuming that the distance between the differential access terminal and the existing base station is calculated to be 250 meters according to the above formula, at this time, the position of the differential access terminal may be located at any point on a circle formed by taking the accessed existing base station as a circle center and taking 250 meters as a radius. Then, according to the accessed existing base station cell parameters, when the azimuth angle of the accessed base station cell is determined to be 60 degrees, the corresponding position can fall on the central area corresponding to the azimuth angle of the base station cell. Therefore, the final position of the differential access terminal is the position point which takes the accessed existing base station as the center point, 60-degree azimuth angle as the ray and 250 meters as the distance.
It should be noted that, the distance and the azimuth angle change along with the movement of the differential access terminal, and the location of the differential access terminal determined by the above method is a certain approximate location interval and is not an accurate location because the coverage of the existing base station is in a sector distribution.
In the above embodiment of the present application, the location of each differential access terminal is determined by obtaining the furthest distance covered by the signal corresponding to the deployment scenario of the existing base station currently accessed by each differential access terminal, and according to the call quality parameter value, the call quality standard value, the internet service quality parameter value and the internet service quality standard value of each differential access terminal, the determined distance attenuation ratio, so as to prepare for determining the differential area according to the location of the differential access terminal in the next step.
Further, based on the above embodiment, as shown in fig. 4, fig. 4 is a flowchart of a method for determining a deployment location of a base station according to another embodiment of the present application. As shown in fig. 4, the method can be implemented by:
s401, clustering the positions of the differential access terminals to obtain candidate differential areas in the area to be planned;
after determining the positions of the differential access terminals through the flowchart shown in fig. 3, clustering the positions of the differential access terminals through a clustering algorithm, and clustering the positions of the differential access terminals with the number greater than the preset threshold value into a differential area, wherein the distance between the positions of the differential access terminals is within the preset distance threshold value range. Through this step, a plurality of candidate differential areas in the area to be planned are obtained.
S402, determining the area with the number of the differential access terminals exceeding a preset number threshold from the candidate differential areas as the differential area.
After a plurality of candidate differential areas in the area to be planned are obtained, the differential area of the position of the base station is determined from the plurality of candidate differential areas.
Alternatively, the determining principle may be whether the number of the differential access terminals exceeds a preset number threshold, and if the number of the differential access terminals in the candidate differential area exceeds the preset number threshold and the position of the differential access terminal meets the construction condition of the base station, the candidate differential area is determined as the differential area where the base station is deployed. The construction conditions can be whether the machine room of the supporting facility of the base station meets the establishment requirements during construction, whether the height of the antenna can be reached under the condition that the machine room meets the requirements, whether the shadow effect influence of the floor exists, and the like.
Further, determining the center of the differential area as a base station deployment position; or determining the deployment position of the base station according to the distribution position of the differential access terminals in the differential area.
The method of determining the center of the differential area as the deployment position of the base station is simpler in the implementation process, but the problem that the position is not accurate is likely to exist. The method of determining the deployment position of the base station according to the distribution position of the differential access terminal in the differential area is more accurate although the process is increased, for example, the deployment position of the base station may be determined at a position where the distribution position of the differential access terminal in the differential area is more concentrated, and optionally, the method of determining a position where the distribution position is more concentrated may be through clustering, and the like, which is not described herein.
In the above embodiment of the present application, the location of the base station is directly deployed on the differential area by determining the differential area by performing clustering processing on the location of each differential access terminal, so that the differential area existing in the area to be planned is reduced from the source, and the communication quality requirement of the user is satisfied. Meanwhile, subsequent maintenance of the poor sense area by the operator is avoided, and labor cost of the operator is saved.
