Cell state judgment method and device based on minimization of drive tests, and computing equipment

[0026] Exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present invention are shown in the drawings, it should be understood that the invention may be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided for more thorough understanding of the present invention and to fully convey the scope of the present invention to those skilled in the art.

[0027] figure 1 A schematic flowchart of a method for judging a cell state based on a minimum drive test provided by an embodiment of the present invention is shown. like figure 1 As shown, the cell state judgment method based on the minimization of drive test includes:

[0028] Step S11: Obtain recorded MDT data and instant MDT data.

[0029] The embodiment of the present invention utilizes Minimization Drive Test (MDT) data, and the main data basis is the longitude and latitude data reported in the MDT. According to the 3rd Generation Partnership Project (3GPP) R10 version, the geographic location information reporting in the MDT measurement report adopts a best-effort method, that is, if the terminal (UE) has available detailed geographic location information (such as GPS information, etc.) ), the UE needs to report it (such as longitude, latitude, altitude, speed, direction, etc.), otherwise, the MDT measurement report only needs to carry the physical-layer cell identity (PCI)/ A primary scrambling code (Primary scrambling code, PSC) and a reference signal received power (Reference Signal Receiving Power, RSRP)/received signal code power (Received Signal Code Power, RSCP) are sufficient. In the embodiment of the present invention, the MDT data with latitude and longitude reporting capability can be used to obtain full coverage capabilities of the RRC idle state and the RRC connected state.

[0030]MDT data configuration can be divided into signaling-based and management/area-based. In signaling-based MDT, an Operation Administration and Maintenance (OAM) tool selects a UE to perform MDT according to a permanent identity of the UE, and is mostly used for network quality analysis of specific user behavior. The permanent identity of the UE may be an International Mobile Subscriber Identification Number (IMSI) or an International Mobile Equipment Identity (IMEI). Based on management/regional MDT, UE selection is performed by the base station (E-NodeB), mainly based on the parameters received from OAM, UE wireless capabilities, and the "MDT permission flag" received from CN during the relevant signaling process. ". Since the embodiment of the present invention needs to perform statistics on a large amount of data, the data configuration adopted is based on management/area MDT data.

[0031] MDT data can be divided into recorded MDT data (Logged data) and instant MDT data (Imm data) from the measurement and reporting modes. Among them, recording MDT data is generally applied when the UE is in the RRC idle state, and the main behavior includes reselection. The UE collects the information of the cell it is in according to the time and frequency indicated by the system, and reports the measurement report after the UE is in the RRC connection state. Part of the field information for recording MDT data is shown in Table 1. The real-time MDT data is applied to the UE in the RRC connection state, and the collected network data is reported immediately. Some field information of instant MDT data is shown in Table 2. Wherein, the MME UE S1AP ID is used for a mobility management entity (Mobility Management Entity, MME) to uniquely identify a UE in the S1 interface. MME GroupID is the MME group ID, and MME Code is the MME number. The field information mainly used in the recorded MDT data and the instant MDT data in the embodiment of the present invention includes the serving cell ID and the longitude and latitude of the UE. Since the recorded MDT data can collect and report the full amount of terminal idle state coverage capabilities, the idle state coverage capabilities can be comprehensively analyzed.

[0035]

[0036] Step S12: According to the recorded MDT data in the geographical area grid, obtain the primary server cell to which the RRC idle user belongs.

[0037] The recorded MDT data includes at least the ECI of the serving cell and the longitude and latitude of the user terminal. In step S12, the ECI of the serving cell and the longitude and latitude of the user terminal are sorted out from the recorded MDT data. Then according to the longitude and latitude of the user terminal, the 4 digits after the decimal point of the longitude and latitude are used as the basis for judging, and it is judged that the RRC idle state user in the 11m*11m geographic area grid belongs to the primary server cell. After sorting the raster as figure 2 As shown, the oblique area indicates that the XX Middle School North-52 community has appeared in the sampling point information, and the dotted area indicates that the XX Hotel-53 community has appeared in the sampling point information.

[0038] In the embodiment of the present invention, the cells whose sampling ratio in the recorded MDT data in any grid is greater than 90% are the main serving cells to which the users in the RRC idle state belong. like image 3 As shown, XX Middle School North-52 district appears in the grid representation sampling point information of area b1 and area b2, and the proportion of sampling points of XX Middle School North-52 district in the grid representation of area b1 is greater than 90%. XX Hotel-53 community appears in the grid representation sampling point information of area a1 and area a2, and the proportion of sampling points where XX Hotel-53 community appears in the grid representation of area a1 is greater than 90%. In the embodiment of the present invention, the first primary server cell in the RRC idle state and the second primary server cell in the RRC idle state can be obtained according to the proportion of sampling points of the primary server cell to which the user in the RRC idle state belongs. Wherein, the proportion of sampling points of the first master serving cell in the RRC idle state is greater than the proportion of sampling points of the second master serving cell in the RRC idle state.

[0039] Step S13: Acquiring the home primary server cell of the RRC connected user according to the real-time MDT data in the geographical area grid.

[0040] The instant MDT data includes at least the ECI of the serving cell and the longitude and latitude of the user terminal. In step S13, the ECI of the serving cell and the latitude and longitude of the user terminal are sorted out from the real-time MDT data. Then according to the longitude and latitude of the user terminal, the 4 digits after the decimal point of the longitude and latitude are used as the basis for judging, and it is judged that the user in the RRC connection state in the 11m*11m geographic area grid belongs to the primary server cell. In the embodiment of the present invention, the cells whose sampling ratio in the real-time MDT data in any grid is greater than 90% are the main serving cells to which the users in the RRC connected state belong. In the embodiment of the present invention, the first primary server cell in the RRC connection state and the second primary server cell in the RRC connection state can be obtained according to the ratio of sampling points of the primary server cell to which the user in the RRC connection state belongs. Wherein, the proportion of sampling points of the first master server cell in the RRC connection state is greater than the proportion of sampling points of the second master server cell in the RRC connection state.

[0041] Step S14: According to the primary service cell to which the RRC idle user belongs and the primary service cell to which the RRC connected user belongs, it is judged whether the RRC idle state and the RRC connected state of the cells in the geographical area grid are consistent.

[0042] In step S14, determine whether the RRC idle state of the cell in the geographical area grid is consistent with the RRC connected state, that is, determine whether the primary server cell to which the RRC idle state user belongs is the same as the RRC connected state user to the primary server cell in the geographical area grid . If the RRC idle state user in any grid belongs to the primary server cell and the RRC connected state user belongs to the primary server cell, it is determined that the RRC idle state of the cell in the grid is consistent with the RRC connection state.

[0043] In any grid, when the RRC idle state user's home primary server cell is inconsistent with the RRC connected state user's home primary server cell, compare whether the RRC idle state user's home primary server cell is the same as the RRC connected state user's home primary server cell. same frequency. If the primary server cell to which the user in the RRC idle state belongs has the same frequency as the primary server cell to which the user in the RRC connected state belongs, it is determined that the RRC idle state of the cell in the grid is inconsistent with the RRC connected state. Since the load balancing strategy is enabled on the current network, the multi-layer network coverage area, the user RRC idle state and the RRC connected state reside in different strategies, so there may be different primary server cells in the idle state and connected state in the same geographical area. The embodiment of the present invention can compare and analyze the coverage capabilities of the RRC idle state and the RRC connected state, so as to determine whether there is an inconsistency between the RRC idle state and the RRC connected state of the cell.

[0044] like Figure 4 As shown, XX Middle School North-52 community appears in the grid representation sampling point information of area b1, area b2, and area b3, and the proportion of sampling points of XX Middle School North-52 community in the grid representation of area b1 and area b3 is greater than 90%, the grid of area b1 indicates that the coverage of the RRC idle state and RRC connected state of the cell is consistent, both of which are XX Middle School North-52 cell. XX hotel-53 community appears in the grid representation sampling point information of area a1, area a2, and area a3. Among them, the grids of area a1 and area a3 indicate that the proportion of sampling points in the XX Hotel-53 community is greater than 90%, and the grid of area a1 indicates that the coverage of the RRC idle state and RRC connected state of the cell is consistent, both of which are XX Hotel-53 community. The MDT data of the whole region are sorted out as shown in Table 3.

[0046]

[0047]

[0048] Wherein, ECI is a cell unique identification code. Idle master server 1 means the first master server cell in the RRC idle state, and idle master server 2 means the second master server cell in the RRC idle state. The master server 1 in the connected state means the first master server cell in the RRC connection state, and the master server 2 in the connected state means the second master server cell in the RRC connection state. Grid number 1 can represent Figure 4 In the area a1, the grid number 2 can represent Figure 4 In the area a3, the grid number 3 can represent Figure 4 In the area a2, the grid number 4 can represent Figure 4 In the region b2, the grid number 5 can represent Figure 4 In the region b3, the grid number 6 can represent Figure 4 area b1 in . It can be known from Table 3 that grid 1 and grid 6 are consistent grids covered by RRC idle state and RRC connected state.

[0049] When the coverage of the RRC idle state and the RRC connected state of the cell is inconsistent, users will switch to the RRC connected state after initiating services from the RRC idle state. The user's initial business stage rate affects user perception. To solve this problem, as Figure 5 As shown, the method for judging the cell state based on the minimized drive test in the embodiment of the present invention also includes:

[0050] Step S15: Calculate the cell-level coverage consistency of any cell.

[0051] The cell-level coverage consistency satisfies the following relational expression: the cell-level coverage consistency = the primary server cell to which the RRC idle state user belongs is the same as the grid of the first cell to which the RRC connected state user belongs to the primary server cell Number/the grid number of the first cell where the RRC idle state user belongs to the primary serving cell. against Figure 4 For the XX Middle School North-52 community in , the coverage consistency at the cell level is the number of grids in area b1/(the number of grids in area b1+the number of grids in area b3). For the XX Hotel-53 cell, the cell-level coverage consistency is the number of grids in area a1/(the number of grids in area a1+the number of grids in area a3). In the embodiments of the present invention, the severity of the inconsistency between the RRC idle state and the RRC connected state of the cell is measured by defining the cell-level coverage consistency, and then corresponding measures may be considered for improvement.

[0052] Step S16: When the cell-level coverage consistency is lower than a preset threshold, adjust cell reselection parameters or handover parameters to ensure consistent coverage between the RRC idle state and the RRC connected state.

[0053] When the cell-level coverage consistency of a cell is lower than the preset threshold, it indicates that the cell has a serious problem that the coverage of the RRC connected state is smaller than the coverage of the RRC idle state, which will directly cause the users in the grid of the cell to change from the RRC idle state to the RRC connection After the state, even if the user does not move, the handover will be initiated immediately. For cells whose cell-level coverage consistency is lower than the preset threshold, adjust and modify the cell reselection parameter (Qoffset) or handover parameter (CellIndivOffset, CIO), so as to adjust the coverage area in different states to ensure the coverage of RRC idle state and RRC connected state The ability is the same. Wherein, the preset threshold is preferably 60%, which can be set according to user needs, and is not limited here. In the embodiment of the present invention, when the degree of inconsistency between the RRC idle state and the RRC connected state of the cell is relatively serious, the number of unnecessary handovers can be reduced through parameter adjustment, thereby increasing the rate of the user's initial service phase and optimizing user perception.

[0054]In the embodiment of the present invention, by obtaining recorded MDT data and instant MDT data; in the geographical area grid, according to the recorded MDT data, the home server cell of the RRC idle state user is obtained; in the geographical area grid, according to the instant MDT data Obtain the primary server cell to which the RRC connected state user belongs; judge whether the RRC idle state of the cell in the geographical area grid is consistent with the RRC connected state according to the primary server cell to which the RRC idle state user belongs and the RRC connected state user to the primary server cell , can accurately and fully obtain the coverage capabilities of the RRC idle state and business state of the cell, and then can reduce the number of unnecessary handovers through parameter adjustment.

[0126] In any grid, when the RRC idle state user's home primary server cell is inconsistent with the RRC connected state user's home primary server cell, if the RRC idle state user's home primary server cell is different from the RRC connected state user's home primary server cell If the cells have the same frequency, it is determined that the RRC idle state of the cell in the grid is inconsistent with the RRC connected state.

[0127] In an optional manner, the program 710 enables the processor to perform the following operations:

[0128] Calculate the cell-level coverage consistency of any cell;

[0129] When the cell-level coverage consistency is lower than a preset threshold, cell reselection parameters or handover parameters are adjusted to ensure consistent coverage between the RRC idle state and the RRC connected state.

[0130] In an optional manner, the cell-level coverage consistency satisfies the following relationship: the cell-level coverage consistency = the primary server cell to which the RRC idle state user belongs and the primary server cell to which the RRC connected state user belongs It is consistent and is the grid number of the first cell/the grid number of the primary serving cell of the RRC idle state user being the first cell.

[0131] In the embodiment of the present invention, by obtaining recorded MDT data and instant MDT data; in the geographical area grid, according to the recorded MDT data, the home server cell of the RRC idle state user is obtained; in the geographical area grid, according to the instant MDT data Obtain the primary server cell to which the RRC connected state user belongs; judge whether the RRC idle state of the cell in the geographical area grid is consistent with the RRC connected state according to the primary server cell to which the RRC idle state user belongs and the RRC connected state user to the primary server cell , can accurately and fully obtain the coverage capabilities of the RRC idle state and business state of the cell, and then can reduce the number of unnecessary handovers through parameter adjustment.
