Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, 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 some embodiments of the present application, but not all 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.
The terms "first," "second," and the like in the description and in the claims, and in the drawings, if any, are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used is interchangeable under appropriate circumstances such that the embodiments of the invention described herein are capable of operation in sequences other than those illustrated or 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, 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 introducing the embodiments of the present application, the background of the present application will be explained first.
The beamforming technology is a technology that by adjusting the amplitude and phase of the transceiver unit of each antenna array, the transmitting/receiving signals of the antenna array in a specific direction are mutually superposed, and the signals in other directions are mutually offset. The beamforming technology greatly improves the system capacity and the spectrum utilization rate of 5G.
For a 5G network, a multiple-in multiple-out (MIMO) technology and a beamforming technology are the most important 2 of wireless air interface technologies. The multi-user MIMO technology realizes the multiplexing of user data at an air interface, the beamforming technology solves the problems of large medium-high frequency signal loss and poor coverage effect, and on the basis, optimizing personnel can exert the coverage efficiency of the wireless base station to the maximum extent as long as the optimizing personnel can accurately position the occurrence position of the user communication service and select proper beamforming parameters.
In the existing 5G beam configuration selection technical scheme, polling type beam configuration is mainly performed on cells, and finally, a beam configuration corresponding to the optimal air interface performance is selected by comparing cell performance indexes of each type of beam configuration.
However, in the actual process, the prior art has the following problems:
1. the period of the beam configuration is long: because each cell needs to select 1 Single Side Band (SSB) primary scene configuration, and then sequentially execute a plurality of SSB secondary scene configurations. In order to ensure the objectivity of the comparison data, each configuration combination needs to be kept for at least several days, so that the whole configuration selection period is long in time;
2. the impact of the time dimension on the beam configuration is neglected: for example, a cell covering an office building performs different beam configuration comparisons on weekends and non-weekends, and the user scale, index performance, and the like cannot be directly used for comparison.
In view of the above technical problems, the inventive concept of the present application is as follows: in the process of configuring the beam, the inventor finds that the selection principle of the beam configuration can be returned to the basic technical principle, wherein the difficulty is that the wireless environment is a relatively complex individual, the information such as the height, the floor area and the like of a building cannot be obtained by the current two-dimensional map, and at the moment, the building information can be extracted by virtue of the advantages of the three-dimensional map, the problem of complex wireless environment is solved, and the beam configuration of different cells in different wireless environments is solved.
The technical solution of the present application will be described in detail below with reference to specific examples.
Table 1 shows 17 commonly used beamforming types provided in the embodiments of the present application. Table 2 provides specific coverage scenario types for embodiments of the present application.
Specifically, a suitable beamforming mode pattern may be selected according to a specific coverage scenario of each cell, so as to improve the system capacity and the spectrum utilization of 5G.

and step 31, rasterizing the 5G capability information reported by the UE according to the pre-acquired full measurement report and the preset grid size to obtain a coverage grid of each 5G cell.
In this scheme, in order to determine a target beam configuration mode corresponding to each 5G cell, first, a Measurement Report (MR) of each 5G cell needs to be obtained. The full MR is used for network evaluation for each 5G cell.
In one possible implementation, fig. 4A is a schematic diagram of a current network architecture for acquiring a full MR according to an embodiment of the present application. As shown in fig. 4A, the current network architecture is schematically illustrated as a 5G Non-dependent Networking (NSA) 3X, including: the system comprises a 4G Core network (EPC), a 4G base station, a 5G base station, a mobile phone (terminal) and a shunt control point.
The Long Term Evolution (LTE) -base station eNB serves as a dual-connected primary node MeNB and carries control plane and user plane data, the terminal accesses the EPC through the LTE eNB (4G base station), and the NR gbb (5G base station) serves as a secondary node and carries user plane data.
Optionally, table 3 is a partial procedure for acquiring a full MR provided in the embodiment of the present application; fig. 4B is a schematic diagram of a large data platform according to an embodiment of the present disclosure. Specifically, the acquisition of the total MR will be described with reference to fig. 4A in conjunction with table 3 and fig. 4B.
Table 3:
specifically, when the terminal with the NSA function accesses the EPC, the UE MR-DC Capability in the User Experience (UE) Capability event reports the 5G Capability to the EPC, then the EPC issues a B1 measurement (see "eventB 1_ NR _ r 15" in table 3), and the 5G (5G New Radio, NR) frequency information that needs to be measured by the terminal is sent to the terminal through a Radio Resource Control (RRC) reconfiguration message. And the terminal acquires the NR synchronous signal after receiving the NR synchronous signal, measures the quality of the 5G signal and reports the measurement result to the EPC.
The measurement result exists in a log file Message Logs, the EPC stores the measurement result in an Operation Support System (OSS) vendor, and a big data Analysis platform Geo Analysis acquires the measurement result in the OSS vendor. The Trace of the operation support system is used for debugging a request-response protocol http mode connected with the network server; the EN-DC (EUTRA-NR Dual Connection) X2 uses the Dual Connection of a 4G MeNB as a main node and an SgNB as a secondary node, and is used for providing service for the terminal.

As shown in fig. 4C, the preset grid size may be 50m × 50m, each grid replaces RSRP that may be in the range of 50m × 50m, and the coverage grid with RSRP in the range of 95% to 100% is illustrated in the figure, and a schematic diagram of 93% to 95%, 88% to 93%, 80% to 88%, 70% to 80%, and 0% to 70% of the coverage grid may be included.
And 32, acquiring morphological characteristic information of the building covered by each 5G cell based on the 3D electronic map and the coverage grid of each 5G cell.
In this step, in order to more accurately determine the coverage scene type of the 5G cell, firstly, the wireless environment of the 5G cell needs to be accurately obtained, and the wireless environment can be obtained by a 3D electronic map, and then, according to the information in the 3D electronic map and the coverage grid of each 5G cell obtained in the above step, the morphological feature information of the building covered by each 5G cell is determined.
Optionally, vector information and height information of the building are obtained according to the 3D electronic map, and then the outline information of the building is determined based on the vector information and the height information.
In one possible implementation, in a buildVector file in the 3D electronic map of the input source, height information of a building (described in a subfile attribute of the buildVector) and vector information of the building (described in subfiles of the buildVector, including a coordinate collection of the building) are obtained. Further, fig. 5A is a schematic diagram of contour analysis of a building according to an embodiment of the present application. As shown in fig. 5A, contour analysis is performed according to the height information and the vector information, that is, the original building contour information extracted from the 3D electronic map is cut into a plurality of closed polygons by the same building, and the merging may be nested merging or co-edge merging.
Optionally, the contour is combined based on the contour information of the building and the coverage grid of each 5G cell, and the morphological feature information of the building covered by each 5G cell is obtained according to the combined contour information, the vector information and the height information.
In one possible implementation, fig. 5B is a combined outline schematic diagram of a building provided in the embodiment of the present application. As shown in fig. 5B, the obtained coverage grid of the 5G cell and the contour information of the building may be combined by a three-point positioning method, and information is output: morphological feature information of buildings covered by each 5G cell. The morphological characteristic information of the building can include longitude and latitude, area and height of the building.

In this step, the morphological feature information of the building covered by the 5G cell combines the wireless environment of the 5G cell and the 5G capability information reported by the UE, and for the morphological feature information, determining the coverage scenario of the 5G cell can be implemented in the following two ways:
a first possible implementation: and determining a coverage scene of the 5G cell based on the number of buildings, the height of each building and the occupied area of each building in the morphological characteristic information of the buildings covered by the 5G cell.
A second possible implementation: determining a coverage scene of the 5G cell based on a relation between a distance from the 5G cell to a sea area in morphological characteristic information of a building covered by the 5G cell and a preset distance, wherein the specific situation can be divided into the following situations:
the preset distance may be 50m, or may be another value preset according to actual conditions.
Firstly, if the distance between the 5G cell and the sea area is determined to be less than the preset distance according to the morphological characteristic information of the building covered by the 5G cell, the coverage scene of the 5G cell is of a coverage coastline type.
Specifically, if the linear distance between the 5G cell and the sea area is less than 50m, the 5G cell coverage scene is: type of covered coastline
Secondly, if the distance between the 5G cell and the traffic trunk is determined to be less than the preset distance according to the morphological feature information of the building covered by the 5G cell, the coverage scene of the 5G cell is of a type covering the traffic trunk.
Specifically, if the linear distance between the 5G cell and the traffic trunk is less than 50m, the 5G cell coverage scene is: covering the traffic trunk type.
And step 34, determining a target beam configuration mode corresponding to each 5G cell according to the coverage scene of each 5G cell and the mapping relation between the coverage scene and the beam configuration mode obtained in advance.
In this step, based on the obtained coverage scenario of the 5G cell, and in combination with the mapping relationship between the coverage scenario and the beam configuration mode provided in the embodiment of the present application, that is, table 2, a target beam configuration mode corresponding to each 5G cell is determined, so that each 5G cell can obtain more accurate beam configuration.

And step 35, performing beam configuration on the 5G cells according to the target beam configuration mode corresponding to each 5G cell.
In this step, the beam configuration is performed on each 5G cell according to the obtained target beam configuration pattern corresponding to each 5G cell.
Optionally, if the coverage scene of the 5G cell is a coastline and the corresponding target beam configuration mode is Pattern 5, the horizontal wave width is 25 °, the vertical wave width is 6 °, the downtilt angles are-2-9, and the azimuth angles are-42 are set according to the beam forming type shown in table 1.
According to the beam configuration method provided by the embodiment of the application, rasterization processing is performed on 5G capability information reported by User Equipment (UE) according to a preset grid size through a pre-acquired full measurement report, so that a coverage grid of each 5G cell is obtained; acquiring morphological feature information of a building covered by each 5G cell based on the 3D electronic map and the coverage grid of each 5G cell; aiming at each 5G cell, determining a coverage scene of the 5G cell according to morphological feature information of a building covered by the 5G cell; determining a target beam configuration mode corresponding to each 5G cell according to the coverage scene of each 5G cell and a mapping relation between the coverage scene and the beam configuration mode obtained in advance; and carrying out beam configuration on the 5G cells according to the target beam configuration mode corresponding to each 5G cell. According to the method, the 3D electronic map and the coverage grids of each 5G cell are combined, beam configuration of different application scenes is achieved, compared with the prior art, the beam configuration efficiency of the scheme is higher, and the configuration cycle time is shorter.
Based on fig. 3, fig. 6 is a flowchart of a second embodiment of a beam configuration method provided in the present application. As shown in fig. 6, the step 33 can be implemented by:
and step 61, aiming at each 5G cell, calculating a first proportion of all buildings in the coverage area of the 5G cell to the total area, a second proportion of high-rise buildings to all buildings in the coverage area of the 5G cell, a third proportion of middle-rise buildings to all buildings in the coverage area of the 5G cell and a fourth proportion of low-rise buildings to all buildings in the coverage area of the 5G cell according to morphological characteristic information of the buildings in the coverage area of the 5G cell.
