Detailed Description
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, 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 application.

It is to be understood that the data so used is interchangeable under appropriate circumstances such that the embodiments of the application described herein are, for example, capable of operation in sequences other than those illustrated or otherwise described herein. Furthermore, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed, but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.
Before formally describing the embodiments of the present application, the application scenarios and the problems existing in the prior art of the embodiments of the present application are described with reference to the accompanying drawings.
Fig. 1 is a schematic view of a base station planning scenario applied in the present application, wherein an embodiment of the present application may be applied to the base station planning scenario shown in fig. 1, as shown in fig. 1, it is noted that an operator a has installed four base stations, namely, base stations a1, a2, A3, and a4, in a mobile communication network, and coverage areas of the four base stations are known. When the operator needs to design and optimize the mobile communication network, the operator may statistically analyze the area uncovered by the established base stations a1-a4, for example, the middle area of the four base stations in fig. 1 is uncovered, so that a new base station may be designed in the middle area to achieve full coverage of the middle area of the four base stations; alternatively, the operator may also receive user feedback or complaint, for example, if the customer feedback signal of terminal B1 is good, and the customer complaint signal of terminal B2 located in the middle area of four base stations is poor, the operator may design a new base station at the location of terminal B1 according to the customer complaint. The operator may then further determine the specific location of the newly established base station, so as to provide a reference for network construction and network optimization, and establish a new base station in a currently uncovered area or a coverage area with weaker coverage.
In the above method for planning a base station, although the base station established based on data such as an uncovered area and customer complaints can solve the coverage problem, it is necessary for an installer to install a base station azimuth angle at a specific position by experience or with guidance from a crowded place. For example, fig. 2 is a schematic diagram of distribution of terminal devices within a coverage area of a base station, where fig. 2 shows a distribution situation of terminal devices B at a certain time within the coverage area of the base station a, and the number of terminal devices B located on the left side of the base station a in the figure is obviously greater than the number of terminal devices B located on the right side of the base station a in the figure, so that after determining a specific position a of the base station a, an installer may align a direction angle of the base station a with a left direction in fig. 2 to meet a communication requirement of a greater number of terminal devices.
However, for each base station, the distribution of the terminal devices within the coverage area of the base station may change with time within a day or several days, for example, if the left side of the coverage area of the base station a is a business area and the right side of the coverage area of the base station a is a residential area as shown in fig. 2, the distribution of the terminal devices within the coverage area of the base station a may show more left sides in daytime and more right sides in evening, or show more left sides in week and more night on weekends. Based on that all terminal devices within the coverage area of the base station Report Measurement Report (MR) data to the base station, an operator can indirectly determine the number and distribution of the terminal devices with respect to the number of MR data reported by the terminal devices within the coverage area of the base station. For example, fig. 3 is a schematic distribution diagram of terminal devices in a time period of a base station, fig. 4 is a schematic distribution diagram of terminal devices in another time period of the base station, for example, fig. 3 is a terminal device distribution counted according to the number of terminal devices reporting MR data from 8 o 'clock to 8 o' clock earlier after a coordinate system is established by longitude and latitude in a coverage area of the base station, and fig. 4 is a terminal device distribution counted according to the number of terminal devices reporting MR data from 8 o 'clock later to 8 o' clock earlier on the next day in the same coverage area of the base station. It can be seen that, within a 24-hour range, the distribution conditions of terminal devices in the same base station are different, and if an installer of the base station simply selects and installs the direction angle of the base station according to the distribution of the terminal devices at the current time, once the distribution of the terminal devices within the coverage area of the base station changes, the direction angle of the base station cannot completely adapt to the change, so that the communication efficiency between the base station and the terminal devices is reduced.
In summary, when the prior art is adopted to plan a base station, parameters such as a direction angle of the base station cannot be planned during base station planning, so that the planning comprehensiveness and flexibility are poor, and further, the communication efficiency of the base station is reduced.
Therefore, the present application provides a method and an apparatus for planning a base station, and a base station, which further determine direction angles of the base station at different time periods through MR data during planning of the base station, so as to improve the comprehensiveness of planning the base station, and improve the flexibility of planning the direction angles of the base station, so as to further improve the communication efficiency of the base station.
The technical solution of the present application will be described in detail below with specific examples. The following several specific embodiments may be combined with each other, and details of the same or similar concepts or processes may not be repeated in some embodiments.
Fig. 5 is a schematic flow chart of a base station planning method provided in the present application, where the method shown in fig. 5 may be applied to the scenario shown in fig. 1, and plans a direction angle of a new base station based on an existing base station; alternatively, the method can also be applied to the scenario shown in fig. 2, and the direction angle of the existing base station is planned. The method comprises the following steps:
s101: and acquiring first MR data reported by the terminal equipment in each time slot of a plurality of time slots within the coverage area of the first base station.
Specifically, the execution main body of the embodiment may be any electronic device with a related data processing function, for example, a background server set by an operator, or a tablet computer, a notebook computer, or a desktop computer; alternatively, the execution subject of this embodiment may also be a processor in an electronic device, for example: a CPU or GPU, etc.
In S101, in order to plan the direction angle of the first base station, the electronic device serving as the execution subject needs to first acquire the first MR data reported by the terminal device within the coverage of the first base station in each of a plurality of time periods. The multiple time periods may be preset or determined by the electronic device according to an instruction of a user, for example, the multiple time periods may include two time periods from 8 am to 8 pm and from 8 pm to 8 am, in S101, the electronic device acquires all MR data reported by all terminal devices in a coverage area of the first base station in the two time periods from 8 am to 8 pm and from 8 pm to 8 am, records the MR data in each time period as the first MR data, and performs subsequent processing.
Optionally, if the first base station is a set base station, the first base station may be connected to the electronic device, and the first base station acquires MR data reported by all terminal devices received by the first base station within a plurality of time periods, and then sends the MR data to the electronic device; alternatively, the electronic device may also receive the first MR data input by a technician through an interactive device such as a mouse, a keyboard, and the like. If the first base station is a newly added base station which is not set in the plan, the MR data reported by the terminal device within the range of the first base station to other base stations in multiple time periods can be acquired as the first MR data, and the acquisition mode can also be that the electronic device directly receives the first MR data sent by other base stations or receives the first MR data input by a technician.
S102: and determining a direction angle corresponding to each time segment in the plurality of time segments by the first base station according to the first MR data in each time segment acquired in the S101.
Subsequently, in S102, the electronic device plans the direction angle of the first base station according to the first MR data in each time period, and determines a corresponding direction angle of the first base station in each time period. More specifically, after the electronic device determines the position point with the largest number of terminal devices reporting MR data within the coverage area of the first base station according to the number of terminal devices reporting MR data in each direction of the first base station, it determines to adjust the direction angle of the first base station to: and enabling the first sector in the three sectors of the first base station to be opposite to the position point with the maximum number of terminal devices in the time period in each time period.
For example, after determining MR data reported by all terminal devices in multiple time periods of the first base station, for any time period, the number of MR data at each angle may be counted within 360 degrees with the first base station as a center, and assuming that the maximum number of location points are determined to be in the 30-degree direction of the first base station, the first sector of the first base station may be oriented in the 30-degree direction. Meanwhile, the base station generally includes three sectors disposed at intervals of 120 degrees, and thus, after the first sector is determined, the directions of the other two sectors are also determined to be 150 degrees and 270 degrees, respectively, for the time period.
It can be understood that, through the above steps, the direction angle corresponding to the first base station in one time period can be obtained, and through the above steps, the different direction angles corresponding to the multiple time periods can be obtained according to the first MR data of the multiple time periods. Accordingly, the electronic device may represent the directional angles of the first base station at different time periods in the form of a mapping relationship, where the mapping relationship may include a one-to-one correspondence relationship between the first base station and a plurality of directional angles over a plurality of time periods. For example, when a time range of 7 days of the week within the coverage of the first base station of the week is acquired, the time period 1: 8 am early-8 a late and time period 2: in two different time periods, namely 8 o 'clock late-8 o' clock early, the first MR data reported by the terminal device may determine that the direction angle corresponding to the first base station in time period 1 is 30 degrees, and the direction angle corresponding to the first base station in time period 2 is 60 degrees through the above steps. Therefore, the recordable mapping relationship includes "time period 1-30 degrees" and "time period 2-60 degrees".
Therefore, the base station planning method provided in the embodiment of the present application can further plan the direction angle of the base station in different time periods through the MR data in the coverage area of the base station when the base station is planned, so as to improve the comprehensiveness of planning the base station, and improve the flexibility of planning the direction angle of the base station, so as to further improve the communication efficiency of the base station.
Further, the above embodiments show a method for planning the direction angle of the first base station, and then for the first base station, after determining the direction angles of the first base station in different time periods, the first base station may adjust the direction angle at different time points in actual operation. For example, fig. 6 is a schematic flow chart of adjusting a direction angle by a base station according to this embodiment, and the method shown in fig. 6 may be used in any base station capable of adjusting a direction angle, or may be the first base station in the embodiment shown in fig. 5. Alternatively, the method shown in fig. 6 may be performed separately in the case that the mapping relationship has been determined, without the procedure of determining the direction angle in the embodiment shown in fig. 5. Specifically, the method shown in fig. 6 includes:
s201: determining a target direction angle of the first base station in a target time period to which the current time belongs according to the current time of the first base station and the mapping relation between the first base station and the plurality of direction angles in the plurality of time periods; the plurality of time periods are in one-to-one correspondence with the plurality of direction angles, and the mapping relation is determined according to measurement report MR data reported by terminal equipment in the coverage area of the first base station in the plurality of time periods.
The execution main body of this embodiment may be a base station, or may be a functional module disposed on the base station, or may also be a processor in the base station, and a mapping relationship may be stored in the base station, where the mapping relationship includes: a plurality of time periods, and a one-to-one correspondence between directional angles of the base station at each of the plurality of time periods. The base station determines the current time in S201, and the base station may perform the embodiment once every preset time.
Specifically, the base station adjusts the actual direction angle of the base station according to the current time falling within a certain time period and further according to the direction angle corresponding to the time period in the mapping relationship. Illustratively, the mapping relationship may include "period 1: early 8 o 'clock-late 8 o' clock-30 degrees "," time period 2: 8 o 'clock late-8 o' clock early-60 degrees ', when the current time is determined to be 9 o' clock early, the direction angle corresponding to the time slot 1 to which the current time belongs in the mapping relationship may be further adjusted to 30 degrees, and the direction angle of the base station may be adjusted to 30 degrees.
S202: and determining the direction angle of the base station adjusted according to the target direction angle.
Subsequently, the electronic device as the execution subject of the present embodiment may determine that the direction angle of the base station is adjusted according to the target direction angle determined in S201. And for the electronic equipment with the display screen, the determined direction angle can be displayed on the display interface of the display screen, so that an operator can know the direction angle required to be adjusted according to the display interface. Alternatively, when the electronic device is connected to the first base station, after S202, the electronic device may directly adjust the direction angle of the first base station, and adjust the direction angle of the first base station to the target direction angle.
In summary, in this embodiment, the base station can be adjusted to different direction angles in different time periods, and the corresponding relationship between the different time periods and the direction angles is determined according to the MR data of the base station in the embodiment shown in fig. 5, so that the base station can always face the direction with a large number of terminal devices in the coverage area of the base station in the different time periods, thereby improving the flexibility of planning the direction angles of the base station, and meeting the requirement of the base station on the communication efficiency in the different time periods.
In the embodiments shown in fig. 5 to 6, the direction angle of the first base station is planned on the basis that the location of the first base station is known, and in some application scenarios, when the location of the first base station is not determined, the electronic device serving as the implementation subject of this embodiment needs to determine the location of the first base station first and then determine the direction angle of the first base station. Therefore, the present application further provides a base station planning method, before planning the direction angle of the first base station in the above embodiment, further including: acquiring second MR data reported by terminal equipment in the coverage area of at least one second base station; subsequently, the position of the first base station is determined according to the second MR data.
Specifically, in this embodiment, since the location of the first base station is not determined, the location of the first base station may be determined according to MR data reported by the terminal device and received by other second base stations around the first base station, so as to supplement the coverage of the other second base stations through the first base station. For example, this embodiment may be applied to the scenario shown in fig. 1, where it is noted that at least one second base station includes the base stations a1-a4 in the figure, and in order to determine the position of the first base station a5 newly added among four second base stations, the position of the first base station may be determined according to MR data of the terminal device received by the base stations a1-a4, and finally the first base station a5 shown in fig. 7 is obtained, where fig. 7 is an application scenario diagram for planning the first base station provided in this application.
More specifically, because the MR data includes Reference Signal Receiving Power (RSRP) loss measured by the terminal device, the MR data reported from all terminal devices in the coverage of the second base station may be determined first and recorded as the second MR data; and then determining a first position point with RSRP loss meeting a preset condition in the range of the second base station according to the second MR data, and finally determining the first position point as the position point of the first base station.
Exemplarily, fig. 8 is a schematic diagram for determining a location point of a first base station provided by the present application, where 6 base stations a located around in the drawing are denoted as second base stations in the present embodiment, and 1 base station B located in the middle in the drawing is denoted as the first base station in the present embodiment. The electronic device may collect the MR data reported by the 6 base stations a within a period of time, perform coverage evaluation on the collected MR data, and output a map of RSRP loss and MR sampling points of the signal strength of a 50M × 50M grid covered by the current base station as shown in fig. 8. Then, on the grid as shown in fig. 8, based on the coverage or traffic target, a new site of the first base station and the grid corresponding to the site of the first base station are planned, the cells covering the grid are filtered according to a certain condition (RSRP loss value is greater than-120 dBm), and the average outwood RSRP of each cell in the grid is calculated. And assuming that the planned antenna height of the site of the first base station is as high as the height of the cells of the surrounding second base stations (generally, the average station height of the second base stations around the periphery is taken as the newly planned station), calculating the path loss of each phase cell of each cell of the grid on the straight line of the return source cell. Subsequently, assume that the grid in which the base station B is located in the figure receives the radio signals transmitted from the 6 surrounding base stations a, and the level value of each cell in the grid is greater than the preset threshold (-120 dBm). Assume that the RSRP loss value of the base a cell at this grid is-100 dBm and the RSRP loss value of the base a cell at the grid where base a is located is-80 dBm, so that the relative loss between the grids where base a and base B are located is 20 dB. Then, the grid where the base station B is located in the figure is gradually diffused outwards, and the relative loss from the peripheral grid to the base station A is calculated, so that the relative loss from the base station A to the grid where the newly planned base station B is located and the peripheral grid can be obtained. Similarly, the relative loss from the other 5 base stations to the grid in which the base station B is located and the surrounding grids can be calculated. Wherein, the signal intensity of the cell of the base station B is received by the grid of the base station B, and the calculation is carried out according to the following method: the RSRP losses of the cell signals received by the neighboring 6 base stations on the respective base station grids are averaged to obtain the RSRP loss of the signal received by the base station B in the yellow grid area. Finally, the calculated relative loss is combined to calculate the RSRP loss of the grid where the new planning site is located and the peripheral grid.
