Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1, a schematic flow chart of a method for centralized power supply of a base station cluster according to an embodiment of the present invention is shown, where the method includes steps S1 to S4:

And S4, analyzing the coverage area of the preselected node station group by adopting a preset coverage area judgment condition according to the preselected node station group to obtain a final selected node station group so as to supply power to all base stations in the coverage area of the final selected node station group.
The embodiment of the invention discloses a centralized power supply method for a base station cluster, which adopts a micro-grid centralized power supply mode, and performs centralized power supply on base stations (namely micro-grid sharing stations) in the coverage range of a micro-grid node station through the micro-grid node station, so that all the base stations can realize power supply, and the difficulty of power supply and the operation and maintenance cost are reduced.
In a specific embodiment, referring to fig. 2, the structural diagram of a base station micro-grid of the centralized power supply method for a base station cluster according to the embodiment of the present invention is shown, and the diagram only schematically shows four sharing stations of a micro-grid, which does not represent an actual situation. The micro-grid node station is a base station unit which is composed of a micro-grid node station and a plurality of micro-grid sharing stations, the micro-grid node station provides power supply for all base stations in the micro-grid unit, the micro-grid node station takes a city center as a main power supply, is provided with communication power supply equipment and a storage battery pack, is a re-protection base station which needs to generate power in time when the commercial power is interrupted, and is also a core base station of the micro-grid unit, the micro-grid sharing station is a base station within the coverage range of the node station, and is not provided with the communication power supply and the storage battery pack in principle, the micro-grid node station provides power guarantee, and.
Further, according to the crowd density threshold, performing cluster analysis on the power supply region according to a preset clustering algorithm to obtain a cluster analysis result, specifically:
and according to the crowd density threshold, performing cluster analysis on the power supply area by adopting a DBSCAN algorithm to obtain a cluster analysis result.
In a specific embodiment, referring to fig. 3, a hot spot distribution diagram of a centralized power supply method for a base station cluster according to an embodiment of the present invention is obtained by using a preset clustering algorithm and using a density-based clustering concept, that is, requiring that the number of objects (i.e., people) included in a certain area in a clustering space is not less than a given density threshold (i.e., a crowd density threshold), to obtain a cluster analysis result, where the cluster analysis result mainly refers to a distribution result of crowd hot spots and hot spot boundaries in the power supply area.
It should be noted that, in specific implementation, other clustering algorithms besides the DBSCAN algorithm may also be used to perform cluster analysis on the power supply region, which is not limited herein.
It should be noted that the magnitude of the density threshold is different according to different scenes, such as in a dense urban area, the density threshold is likely to be set to 1000 people per square kilometer, but in a suburban area or rural area, it is likely to be set to 200 people per square kilometer. The reason for selecting density thresholds with different values is to find out relatively dense places which are likely to serve as representative regions of crowd gathering, and generally, for the regions of crowd gathering, it is certain that the base station needs to be ensured to be turned on for a long time and the requirements of users need to be met, so that the power supply needs to be started for a long time, and therefore, the density thresholds are taken as node stations and serve as energy supply points of the sharing station, and the density thresholds are most suitable.
On the basis of the foregoing embodiment, further, according to the cluster analysis result and according to a preset node station selection method, all base stations in the power supply area are screened to obtain a preselected node station group, and the specific steps include:
and selecting the base station which is closest to each hot spot in the cluster analysis result and has the best comprehensive matching condition as a node station according to the cluster analysis result, and screening all the base stations in the power supply area to obtain a preselected node station group.
It should be noted that, since the hot spot is likely not to be repeated with the base station in a geographical location, and the node station is used as a center of the whole microgrid grid and is responsible for energy supply of all base stations in the whole microgrid, the configuration of the node station must be sufficient and stable, so that the base station with the best comprehensive matching configuration condition nearest to the hot spot can be used as a first choice of the node station to obtain the preselected node station group.
On the basis of the foregoing embodiment, further, the analyzing, according to the preselected node station group, the coverage of the preselected node station group by using a preset coverage determination condition to obtain a finally selected node station group, so as to supply power to all base stations within the coverage of the finally selected node station group specifically includes:
analyzing the coverage range of the preselected node station group according to a pre-acquired preset coverage range formula according to the preselected node station group, and judging whether the coverage range of the preselected node station group meets the requirement of the preset coverage range formula;
and if the coverage area of the preselected node station group meets the requirement of the preset coverage area formula, determining the finally selected node station group as the preselected node station group.
It should be noted that, in specific implementation, the preset coverage formula may be set according to actual needs, and is not limited herein.
It should be noted that, in this embodiment, the coverage area of the preselected node station group is analyzed through the preset coverage area formula, and only when the coverage area of the preselected node station group meets the requirement of the preset coverage area formula, the node station group selected finally is determined to be the preselected node station group, so that it can be ensured that the node station group selected finally can cover all the sharing stations of the microgrid, and it is ensured that all the base stations can normally operate in busy service, thereby reducing difficulty in power supply and operation and maintenance cost.
Illustratively, since there is a certain gap between different communication power supply devices, the coverage area of each node station may be different, and therefore the preset coverage area formula is composed of an objective function and a constraint condition that minimize the overlapping degree of the coverage areas of the base stations, which are specifically as follows:
wherein S isiIndicates the site area of the i-th node station, SjDenotes a site area of a jth node station, N denotes a node stationS represents the sum of the areas of the site components of all the node stations by addition.
And if the formula meets the requirement, the preselected node station group is satisfied, and the finally selected node station group is determined to be the preselected node station group.
It should be noted that, in general, the coverage area of an ideal base station is irregular and has a shape of a thiessen polygon, but actually, the coverage areas of the base stations are crossed, and the invention is a research combining the situation of the coverage area of a real base station.
On the basis of the foregoing embodiment, further, the analyzing, according to the preselected node station group, the coverage of the preselected node station group by using a preset coverage determination condition to obtain a finally selected node station group, so as to supply power to all base stations within the coverage of the finally selected node station group, further includes:
and if the coverage range of the preselected node station group does not meet the requirement of the preset coverage range formula, adjusting the crowd density threshold value in the power supply area according to a preset step length, obtaining the adjusted preselected node station group according to the adjusted crowd density threshold value, and analyzing the coverage range of the adjusted preselected node station group.
It is worth mentioning that when the coverage of the preselected group of nodal stations does not meet the requirement, the value of the crowd density threshold is adjusted until the coverage of the preselected group of nodal stations is adjusted to meet the requirement.
Illustratively, the preset initial value of the step length needs to be considered in the scenario of the node station, for example, if it is in a rural area, the step length may be initially set to about 200, because one rural area is about 200 people per square kilometer, while in a general city, the initial setting is preferably about 1000 people, and for a super-large city, it is preferably about 2000 people, and the step length needs to be set according to the scenario of the base station, preferably about 3% -5% of the initial setting value is added or subtracted, that is, the step length of 3% -5% of the initial value is optimized each time.
Illustratively, if the coverage area of the preselected node station group does not meet the requirement of the preset coverage area formula, it indicates that the value of the initially set population density threshold is too large, and the step size is set to gradually reduce according to the step size, and as the density threshold is continuously reduced, when the coverage area of the preselected node station group meets the requirement of the preset coverage area formula, the base stations (including macro base stations and micro base stations) within the coverage area of the node station can be brought into the management range of the base station micro grid.
When the initial crowd density threshold is set, a reasonable numerical value is set according to actual conditions, if the numerical value is too small, preselected node station groups are too many, and energy conservation and environmental protection cannot be achieved.
Further, the method further comprises:
constructing a target function which meets the minimum starting number of base stations in the coverage range of the finally selected node station group; the constraint conditions of the objective function comprise a constraint condition of a coverage area of a started base station, a constraint condition of standard field intensity and a constraint condition of signal to noise ratio;
and on the basis of meeting the target function and the constraint condition, obtaining a control strategy result of the base station within the coverage range of the finally selected node station group according to the started base station.
It should be noted that, in implementation, the objective function and the constraint condition may be set according to actual needs, and are not limited herein.
It should be noted that after the node stations of the micro grid are selected, when the service is in the idle stage, on the basis of ensuring the user performance and not affecting the user QOE (Quality of Experience), energy saving and environmental protection can be achieved by closing part of the micro grid sharing stations and only opening part of the micro grid sharing stations.
Further, the constraint conditions of the objective function include a constraint condition on a coverage area of a base station that is turned on, a constraint condition on a standard field strength, and a constraint condition on a signal-to-noise ratio, and specifically include:
the coverage range of the started base station in the coverage range of the finally selected node station group can cover each grid in the power supply area, the standard field strength of each grid in the coverage range of the started base station can meet the minimum field strength standard of each grid, and the signal-to-noise ratio of each grid in the coverage range of the started base station can meet the average signal-to-noise ratio of each grid.
It is worth mentioning that on the basis of determining the microgrid node stations, if only part of the microgrid sharing stations are started in an idle period, it is necessary to ensure that the started microgrid sharing stations can cover each grid of the area, the standard field strength of each grid in the coverage range of the started base station can meet the minimum field strength standard of each grid, and the signal-to-noise ratio of each grid in the coverage range of the started base station can meet the average signal-to-noise ratio of each grid.
In mobile communication, a geographical location is divided into grids, and MR (Measurement Report) data is reported in a grid manner.
Illustratively, the objective function that satisfies the minimum number of base stations that are turned on within the coverage area of the selected node station group and the constraint condition corresponding to the objective function are specifically:
s.t.aijxi＝1，j＝1，2，...，n
xi∈{0，1}，i＝1，2，...，n
wherein the content of the first and second substances,
Cirepresents the construction and maintenance cost, x, of the node stationiIndicating a base station that needs to be turned on.
In the constraint condition, aijxi1 means that the coverage area of the activated piconet sharing station can cover any one grid j in the power supply area,
the standard field strength representing grid j needs to meet the minimum standard field strength requirement,
the minimum field strength standard value of RSCP (Received Signal Code Power) of each grid j is represented, the field strength of each grid is different under the condition of different coverage of the main base station,
the signal-to-noise ratio representing grid j can satisfy the average signal-to-noise ratio of each grid,
the average signal-to-noise ratio of the grid j is represented, and if the signal-to-noise ratio does not meet the requirement, various communication service requirements of users cannot be met, and the signal is unstable.
It is worth to be noted that the RSCP simulation field strength value of each grid j when different base stations are in sleep can be obtained by a preset simulation method.
Illustratively, the preset simulation method may be simulation by using Atoll software.
When the objective function and the constraint condition are met, a base station control strategy result meeting performance requirements can be obtained based on the started and dormant base stations, and energy conservation and environmental protection are achieved.
Compared with the prior art, the centralized power supply method for the base station cluster disclosed by the embodiment of the invention has the advantages that the micro-grid node stations are selected when the service is busy, all the base stations can be ensured to realize power supply in a micro-grid mode of the base stations, and on the basis of determining the micro-grid node stations, partial base stations are dormant when the service is idle, so that the energy conservation and the environmental protection are realized.

By adopting the embodiment of the invention, all base stations in the grid range can be powered by a centralized power supply mode of the micro grid, and the difficulty of power supply and the operation and maintenance cost are reduced.
