Description

TECHNICAL FIELD

[0001] The present application relates to the field of communication technology, in particular to a method and device for detecting a co-coverage cell and an electronic device. BACKGROUND

[0002] In the field of communication technology, co-coverage refers to a situation where one main service cell and one or more neighboring cells jointly cover an area. Wireless devices at the same room partition physical point are usually provided by different device manufacturers, and accurate identification of co-coverage cells between different manufacturers is a key to optimizing network perception problems such as load balancing and overlapping coverage.

[0003] Currently, the method for identifying co-coverage cells is usually based on geographic information, that is, the co-coverage cells of different manufacturers are manually screened by using more accurate room partition base station longitude and latitude, base station name and other information. However, in actual application, it is difficult to obtain more accurate room partition base station longitude and latitude, and problems such as deviation and loss of longitude and latitude information often occur. In addition, due to different definitions of base station names by different device manufacturers (for example, there are differences in information such as English, keywords, naming methods between base station names), the above factors increase the difficulty of identification based on geographic information, thereby affecting the accuracy of co-coverage cell identification of different manufacturer room partition cells, resulting in low efficiency of co-coverage cell identification.

[0046] Embodiments of the present application provide a method and device for detecting a co-coverage cell and an electronic device.

[0047] In order to make those skilled in the art better understand the technical solutions in the present application, the technical solutions in the embodiments of the present application will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only some embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor should fall within the scope of the present application.

[0048] As shown in Figure 1 Embodiments of the present application provide a method for detecting a co-coverage cell. The execution subject of the method can be a server, which can be an independent server or a server cluster composed of multiple servers. The method can specifically include the following steps:

[0049] In S102, a co-coverage cell detection request is received, and terminal inter-frequency measurement data of a target co-coverage cell, co-coverage cell information and co-coverage cell switching times are obtained according to the co-coverage cell detection request.

[0050] Co-coverage refers to a situation where a main service cell and one or more neighboring cells jointly cover an area. The wireless equipment at the same indoor physical point is usually provided by different equipment manufacturers. Taking the 4G network as an example, in the networking process of the 4G network, the advantages of multiple frequency bands are usually used to adopt different frequencies and co-coverage networking in the indoor system to improve the system capacity. However, due to equipment capabilities, time-sharing construction and other reasons, the wireless equipment at the same indoor physical point is often provided by different equipment manufacturers. It is impossible to simply identify the co-coverage cells from the base station configuration, resulting in missing or inaccurate information on the co-coverage cells, affecting subsequent optimization work such as load balancing and switching. Therefore, the accurate identification of co-coverage cells between different manufacturers is the key to optimizing network perception issues such as load balancing and overlapping coverage.

[0051] Among them, the target co-coverage cell in the embodiment of this specification is a group of cells to be identified as the best co-coverage cell that matches the main coverage cell. The target co-coverage cell includes a main coverage cell and multiple co-coverage neighboring cells corresponding to different terminal equipment manufacturers. It can be a main coverage cell and multiple co-coverage neighboring cells corresponding to different terminal equipment manufacturers (that is, the terminal equipment manufacturer of the main coverage cell and the terminal equipment manufacturers of each co-coverage neighboring area are different, or the terminal equipment manufacturers of each co-coverage neighboring area are the same, but different from the terminal equipment manufacturer of the main coverage cell). It is also possible that the equipment manufacturer of the main coverage cell and multiple co-coverage neighboring areas is the same, but the equipment model, frequency, power and parameter configuration used between each co-coverage neighboring area are different, that is, the equipment configuration parameters of each co-coverage neighboring area are different. The number of co-coverage cell switching is the frequency of users occupying different cells in the overlapping coverage area between the main coverage cell and any co-coverage neighboring area, which can be understood as the number of cell-to-cell switching between base stations. The co-coverage cell information includes latitude and longitude information for indicating the geographical location of the main coverage cell or the co-coverage neighboring area and user time advance information for indicating the distance between the terminal and the antenna interface. The user timing advance information is TA (Timing Advance) information, and the terminal inter-frequency measurement data is MR (Measurement Report) inter-frequency measurement information, referred to as MR report, including multiple measurement data report tables (i.e., MR report tables), each of which includes a multi-hop measurement data report (i.e., MR report).

[0052] The co-coverage cell detection request is usually issued by the user end. The server end responds to the request and performs co-coverage cell detection to determine the best co-coverage neighboring area (i.e., the best co-coverage cell) corresponding to the main coverage cell within the current co-coverage cell group to be tested (target co-coverage cell). Users can screen terminal equipment manufacturers based on the configuration of the best co-coverage cell to carry out subsequent business.

[0053] In implementation, the terminal inter-frequency measurement data of the target co-coverage cell, the co-coverage cell information and the co-coverage cell switching times obtained according to the co-coverage cell detection request can be understood as common data collection of different terminal equipment manufacturers. The terminal inter-frequency measurement data of the target co-coverage cell can include the station number information, the frequency point information, the physical cell identifier of the primary coverage cell and the frequency point information, the physical cell identifier, the average reference signal receiving power of any co-coverage neighbor cell.

[0054] The room division terminal inter-frequency measurement data collection table (or room division MR inter-frequency data collection table) can refer to Table 1 shown as follows.

[0058] In Table 1, SiteId is the station number information of the primary coverage cell (also referred to as the service cell), LteScEarfcn is the frequency point information of the primary coverage cell, MR.LteScPci is the physical cell identifier of the primary coverage cell, LteNcEarfcn is the frequency point information of the co-coverage neighbor cell (also referred to as the neighbor cell), MR.LteNcPci is the physical cell identifier of the co-coverage neighbor cell, MR.LteNcRSRP is the average reference signal receiving power of the co-coverage neighbor cell, and the actual signal level is MR.LteNcRSRP-140, unit dBm.

[0059] In implementation, the co-coverage cell information at least includes the longitude and latitude information and the TA information of the primary coverage cell or any co-coverage neighbor cell, the longitude and latitude information is used to represent the geographical position of the to-be-tested cell, the distance between the to-be-tested cells can be calculated, and the TA information is used to represent the distance between the terminal equipment and the antenna interface. In addition, the co-coverage cell information can also include the station number information, the frequency band information and the physical cell identifier of the primary coverage cell or any co-coverage neighbor cell.

[0060] In implementation, the co-coverage cell information collection table can refer to Table 2 shown as follows.

[0063] The co-coverage cell switching times are used to represent the frequency of the user occupying different cells in the overlapping coverage area between the to-be-tested cells, and the co-coverage cell switching times collection table can refer to Table 3 shown as follows.

[0064] Table 3

[0066] In S104, the total number of occurrences of the neighbor set composed of a plurality of co-coverage neighbor cells corresponding to the main coverage cell is determined according to the terminal inter-frequency measurement data, and the coverage level of the neighbor set is determined, and the candidate co-coverage cell pair corresponding to the main coverage cell is determined according to the total number of occurrences of the neighbor set and the coverage level of the neighbor set.

[0067] In the MR inter-frequency measurement information, a plurality of MR report tables are included, the total number of occurrences of the neighbor set refers to the total number of occurrences of the neighbor set composed of at least two neighbor cells under the main coverage cell in the target co-coverage cell, when calculating the total number of occurrences of the neighbor set, the main coverage cell can be defined by the station number information, the frequency point information and the physical cell identifier of the main coverage cell, and the neighbor set can be defined by the frequency point information and the physical cell identifier of the co-coverage cell. The coverage level of the neighbor set is the average of the levels of the neighbor set in all MR report tables under the main coverage cell in the target co-coverage cell, and when calculating the coverage level of the neighbor set, the main coverage cell can be defined by the station number information, the frequency point information and the physical cell identifier of the main coverage cell, and the neighbor set can be defined by the frequency point information and the physical cell identifier of the co-coverage cell.

[0068] In the implementation, when the candidate co-coverage cell pair corresponding to the main coverage cell is determined according to the total number of occurrences of the neighbor set and the coverage level of the neighbor set, the candidate co-coverage cell pair can be screened according to a preset rule, or the candidate co-coverage cell pair can be manually selected.

[0069] In S106, the best co-coverage cell corresponding to the main coverage cell is determined from the candidate co-coverage cell pair based on the total number of occurrences of the neighbor set, the coverage level of the neighbor set, the number of co-coverage cell handovers, the latitude and longitude information and the user time advance information.

[0070] In implementation, different weights can be respectively given to the total number of occurrences of the neighbor set, the coverage level of the neighbor set, the number of handovers of the co-coverage cell, the longitude and latitude information, and the user time advance information, and the best co-coverage cell is determined based on the given weights, for example, weights 1-5 are respectively given to the above parameters based on the importance of the parameters in determining the co-coverage cell, and then the best coefficient is calculated based on the weights 1-5, so as to determine the best co-coverage cell. Alternatively, the total number of occurrences of the neighbor set and the coverage level of the neighbor set can be used as parameters for preliminary screening of the candidate co-coverage cell, and the number of handovers of the co-coverage cell, the longitude and latitude information, and the user time advance information can be used as parameters for further accurate calculation, two groups of weights are respectively given, and the best co-coverage cell is determined based on the given weights, for example, weight 1 is given to the total number of occurrences of the neighbor set and the coverage level of the neighbor set, and weight 2 is given to the number of handovers of the co-coverage cell, the longitude and latitude information, and the user time advance information, and then the best coefficient is calculated based on the weight 1 and the weight 2, so as to determine the best co-coverage cell.

[0071] The embodiment of the present application provides a detection method of a co-coverage cell, which receives a co-coverage cell detection request, and acquires terminal inter-frequency measurement data of a target co-coverage cell, co-coverage cell information, and the number of handovers of the co-coverage cell according to the co-coverage cell detection request, then determines the total number of occurrences of a neighbor set composed of a plurality of co-coverage neighbor cells corresponding to a main coverage cell and the coverage level of the neighbor set according to the terminal inter-frequency measurement data, and determines a candidate co-coverage cell pair corresponding to the main coverage cell according to the total number of occurrences of the neighbor set and the coverage level of the neighbor set, and finally determines the best co-coverage cell corresponding to the main coverage cell from the candidate co-coverage cell pair based on the total number of occurrences of the neighbor set, the coverage level of the neighbor set, the number of handovers of the co-coverage cell, the longitude and latitude information, and the user time advance information. In this way, the total number of occurrences of the neighbor set and the coverage level of the neighbor set corresponding to the main coverage cell in the target co-coverage cell are determined by using the terminal inter-frequency measurement data, the candidate co-coverage cell pair is preliminarily identified and screened from the massive data, which can greatly reduce the data identification range and is beneficial to improving the efficiency of co-coverage cell identification. Then the best co-coverage cell corresponding to the main coverage cell is determined from the candidate co-coverage cell pair based on the total number of occurrences of the neighbor set, the coverage level of the neighbor set, and the number of handovers of the co-coverage cell, the longitude and latitude information, and the user time advance information, so as to realize more accurate screening and effectively improve the accuracy of co-coverage cell identification.

[0072] In the embodiment of the present application, the processing method of the step S104 is various, and an optional implementation manner is provided below, which specifically includes the following steps S1042-S1044.

[0073] In S1042, based on the terminal inter-frequency measurement data, a clustering method is used to determine the total number of occurrences of the neighbor set composed of the multiple co-coverage neighbor cells corresponding to the frequency band information of the main coverage cell and the coverage level of the neighbor set.

[0074] In S1044, from the determined total number of occurrences of the neighbor set corresponding to the same main coverage cell and the coverage level of the neighbor set, the total number of occurrences of the neighbor set composed of the multiple co-coverage neighbor cells corresponding to the frequency band information of the main coverage cell and the coverage level of the neighbor set, the co-coverage cell pair corresponding to the neighbor set of the main coverage cell whose coverage level is greater than a preset level value and whose total number of occurrences exceeds a preset total number is screened out, and the candidate co-coverage cell pair corresponding to the main coverage cell is determined according to the screened co-coverage cell pair.

[0075] In implementation, taking the main coverage cell of room division manufacturer A and the multiple co-coverage neighbor cells of room division manufacturer B in the target co-coverage cell as an example, and the room division manufacturer A is E frequency band information and the room division manufacturer B is FDD frequency band information. According to the terminal inter-frequency measurement data, the main coverage cell based on E frequency band information clusters the MRcount (the total number of occurrences of the neighbor set) and the AvgLteNcRSRP (the coverage level of the neighbor set) of each FDD frequency band co-coverage neighbor cell under E frequency band.

[0076] In determining the candidate co-coverage cell, the co-coverage cell pair whose coverage level of the neighbor set of the main coverage cell is greater than a preset level value and whose total number of occurrences exceeds a preset total number can be directly screened out as the candidate co-coverage cell pair, and each candidate co-coverage cell pair is a cell pair composed of the main coverage cell and one co-coverage neighbor cell. The neighbor set whose coverage level is greater than a preset level value can also be screened out first, and then the total number of occurrences of the neighbor set is calculated. In calculating the total number of occurrences of the neighbor set, the total number of occurrences of all neighbor sets can be sorted in descending order, and finally the neighbor corresponding to the total number of occurrences of the neighbor set whose coverage level is greater than a preset level value and which is ranked in the top N positions is selected, so as to determine the candidate co-coverage cell pair. The neighbor set whose coverage level is greater than a preset level value can also be screened out first, and then the total number of occurrences of the neighbor set is calculated. In calculating the total number of occurrences of the neighbor set, the total number of occurrences of all neighbor sets can be sorted in descending order, and the total number of occurrences in the Nth position is taken as the preset total number, and finally the neighbor whose coverage level of the neighbor set is greater than a preset level value and whose total number of occurrences of the neighbor set exceeds the preset total number is selected, so as to determine the candidate co-coverage cell pair.

[0077] In implementation, the preset level value can be 40, and N can be 5, that is, the co-coverage neighbor cell whose coverage level of the neighbor set corresponding to the main coverage cell is greater than 40 and whose total number of occurrences is ranked in the top 5 positions in descending order can be screened out, and the candidate co-coverage cell pair is formed by the main coverage cell and the co-coverage neighbor cell.

[0078] As Figure 2 shown in the embodiment of the present application, the processing method of step S106 is various, and an optional implementation is provided below, which specifically includes steps S1062-S1066.

[0079] In S1062, a first coefficient between the candidate co-coverage cell pair corresponding to the primary coverage cell is determined according to the total number of occurrences of the neighbor set composed of multiple co-coverage neighbor cells corresponding to the primary coverage cell, the coverage level of the neighbor set, and a preset first weight.

[0080] In S1064, a second coefficient within the candidate co-coverage cell pair corresponding to the primary coverage cell is determined according to the number of co-coverage cell handovers, the latitude and longitude information, the user time advance information, and a preset second weight.

[0081] In S1066, a comprehensive coefficient of the candidate co-coverage cell pair corresponding to the primary coverage cell is determined based on the first coefficient and the second coefficient, a maximum value of the comprehensive coefficient is determined from multiple comprehensive coefficients, and the best co-coverage cell corresponding to the primary coverage cell is determined according to the maximum value of the comprehensive coefficient.

[0082] By setting the preset first weight and the second weight to determine the comprehensive coefficient of the co-coverage cell pair, different weight values can be assigned to different parameters, which is beneficial to further improve the accuracy of co-coverage cell screening.

[0083] In implementation, the coverage level of the neighbor set can be further divided into intervals and assigned different values, the proportion of the total number of occurrences of the current neighbor cell pair in the sum of the total number of occurrences of the first N neighbor set is assigned a value b, thereby further improving the accuracy of the co-coverage cell detection result. The coverage level value of the neighbor set can be assigned according to the intervals in Table 4 below, and the value is a.

[0086] In the embodiment of the present application, the values of the preset first weight and the preset second weight in steps S1062-S1064 can be various, and one optional weight value is provided below, in which the preset first weight is set to 60%, and the preset second weight is set to 40%. In implementation, the weight of the total number of occurrences of the neighbor set can be set to 30%, the weight of the coverage level of the neighbor set can be set to 30%, and the weight of the sum of the handover number of the co-coverage cell, the latitude and longitude information, and the user time advance information can be set to 40%. The comprehensive weight of a+b can be set to 60%, and the first coefficient X between the candidate co-coverage cell pairs is a*30%+b*30%. The above weight value can determine the best co-coverage cell matching based on the maximum value of a+b corresponding to the neighbor cell pair, and is beneficial to further improve the accuracy of the co-coverage cell detection result.

[0087] Based on the above weight setting, the coefficient table between each candidate co-coverage cell pair in the embodiment of the present application can be referred to Table 5 as shown below.

[0090] In the embodiment of the present application, the processing method of step S1064 can be various, and one optional implementation is provided below, which specifically includes the processing of steps A1-A2.

[0091] In step A1, the first sub-weight, the second sub-weight, and the third sub-weight corresponding to the handover number of the co-coverage cell, the latitude and longitude information, and the user time advance information are respectively determined according to the average distance between each pair of cells with the handover number in the candidate co-coverage cell pair, the average distance between each pair of cells with the latitude and longitude calculation in the candidate co-coverage cell pair, and the average distance between each pair of cells with the same user time advance information, and the first sub-weight is greater than the second sub-weight, and the second sub-weight is greater than the third sub-weight.

[0092] Since each candidate co-coverage cell pair is usually a combination of the frequency point information and the physical cell identifier of the cell, in the actual network, there can be multiple cells with the same frequency point information and physical cell identifier, and a group of frequency point information and physical cell identifier cannot uniquely match a co-coverage cell pair. By respectively assigning different weights to the handover number of the co-coverage cell, the latitude and longitude information, and the user time advance information for comprehensive judgment, the accuracy of the co-coverage cell detection can be further improved.

[0093] In implementation, the average distance between each pair of cells with switching times, the average distance between each pair of cells with latitude and longitude calculation in candidate co-coverage cell pairs, and the average distance between each pair of cells with the same user time advance information, the closer the distance, the higher the probability of generating candidate co-coverage cell pairs, for example: the average distance between each pair of cells with switching times in candidate co-coverage cell pairs is 600 meters, the average distance between each pair of cells with latitude and longitude calculation is 1000 meters, and the average distance between each pair of cells with the same TA value is 1500 meters. Based on the probability of generating candidate co-coverage cell pairs, the weights of Q1, Q2 and Q3 can be set to 50%, 30% and 20% respectively, that is, the closer the distance, the higher the probability.

[0094] In step A2, based on the co-coverage cell switching times and the corresponding first sub-weight, the latitude and longitude information and the corresponding second sub-weight, the user time advance information and the corresponding third sub-weight, and the preset second weight, the second coefficient in the candidate co-coverage cell pair is determined.

[0095] In implementation, continue to take the target co-coverage cell including the primary coverage cell of room division manufacturer A and the plurality of co-coverage neighbor cells of room division manufacturer B as an example, and room division manufacturer A is E frequency band information and room division manufacturer B is FDD frequency band information, and assume that there are 5 groups of candidate co-coverage cell pairs. First, assign values to the three parameters of co-coverage cell switching times, latitude and longitude information, and user time advance information.

[0096] When assigning values to the co-coverage cell switching times, the switching times of all E frequency band and FDD frequency band cell pairs in the 5 groups of candidate co-coverage cell pairs can be calculated, and the greater the switching times, the higher the co-coverage probability. The switching times are arranged in descending order, and the corresponding cell pairs are assigned values of α. The maximum cell pair takes the value of α as 50%, and the cell pairs ranked in the top 10 are retained, and the values are assigned in decreasing order of 5%.

[0097] When assigning values to the latitude and longitude information, the latitude and longitude distance of all E frequency band and FDD frequency band cell pairs in the 5 groups of candidate co-coverage cell pairs can be calculated, and the smaller the latitude and longitude distance, the higher the co-coverage probability. The latitude and longitude distance is arranged in ascending order, and the corresponding cell pairs are assigned values of β. The candidate co-coverage cell pair with the minimum latitude and longitude distance takes the value of β as 30%, and the cell pairs ranked in the top 10 are retained, and the values are assigned in decreasing order of 3%.

[0098] When assigning values to the user time advance information, the TA ratio coefficient γ of E frequency band cell and all FDD frequency band cell pairs in the 5 groups of candidate co-coverage cell pairs can be calculated, and the closer the value to 1, the greater the co-coverage probability. |γ-1| is arranged in ascending order, and the candidate co-coverage cell pair with the minimum |γ-1| value takes the value of 20%, and the cell pairs ranked in the top 10 are retained, and the values are assigned in decreasing order of 2%.

[0099] Finally, the preset second weight value is set to 40%, and the second coefficient Y = (α+β+γ)*40% within the candidate co-covered cell pair is calculated based on the three comprehensive dimensions of the three parameters: the number of co-covered cell switching times, longitude and latitude information, and user time advance information.

[0100] According to the above assignment, the coefficient table within the co-covered cell pair in the embodiment of this specification can be shown in Table 6 below.

[0103] Corresponding to steps A1-A2, in step S1066, the comprehensive coefficient of the candidate co-coverage cell pair corresponding to the primary coverage cell can be calculated according to [a*30%+b*30%+(α+β+γ)*40%]. The co-coverage neighboring cell corresponding to the maximum comprehensive coefficient among the calculated multiple comprehensive coefficients is selected as the optimal co-coverage cell matching the primary coverage cell. The comprehensive coefficient calculation process can be seen in Table 7 below. As can be seen from Table 7, FDD cell 2 is a co-coverage cell of the E-band cell.

[0106] In summary, in the implementation of this specification, taking advantage of the fact that user usage frequency and usage habits are basically the same in two cells when indoor cells from different manufacturers are co-covered, the number of handovers in the co-covered cells and user time advance information are creatively used as the weight basis for user usage habits, and the latitude and longitude information is used as the weight basis for the geographical location. The combined weights of the three account for 40% of the maximum comprehensive coefficient. By quantifying the cell pair relationship value, simple and fast calculations can be achieved, thereby improving the efficiency of co-covered cell detection. Using terminal inter-frequency measurement data, the average level is used as the weight basis for the signal strength of the user terminal in the co-covered neighboring cell (FDD frequency band indoor cell), and the total number of neighboring cell sets is used as the weight basis for the frequency of the terminal detecting the co-covered neighboring cell signal in the main coverage cell (E frequency band indoor cell). The combined weights of the two account for 60% of the maximum comprehensive coefficient. By assigning weights to the two, the cell pair screening range can be significantly reduced, which is beneficial to improving the efficiency and accuracy of co-covered cell detection.

[0107] The principle diagram of the detection method of the co-covered cells in the embodiment of this specification can be found in Figure 3 ,Depend on Figure 3 It can be seen that when performing co-coverage cell detection based on the method in the embodiments of this specification, the following process is mainly included:

[0108] S1: Common data of different terminal equipment manufacturers is sorted. The execution process of step S102 can be referred to.

[0109] S2: Weight calculation of candidate common coverage cells.

[0110] That is, the weight values of the total number of times of occurrence of the neighbor set and the coverage level of the neighbor set are assigned.

[0111] S3: Weight calculation of 1-to-N cells in the candidate common coverage cell.

[0112] That is, the weight values of the number of handovers of the common coverage cell, the latitude and longitude information, and the user time advance information are assigned.

[0113] S4: Comprehensive coefficient calculation. The execution process of step S1066 can be referred to.

[0114] The method based on the embodiments of the present specification can efficiently identify the room split common coverage cell pairs of different manufacturers and determine the best common coverage cell. With the continuous evolution of the network and the arrival of the user replacement period, the 4G network aims to be extremely simple, and thinning and refining are the main direction in the future. With the continuous increase of the shunt ratio, 5G 160M networking becomes an important networking means. In the feasibility evaluation of room split D-band frequency reduction, the overall capacity and utilization of room split physical points are mainly evaluated. The method in the embodiments of the present specification can be used to identify the common coverage cell pairs of the D-band and other manufacturers' bands, so as to judge the network bearing capacity of other 4G frequency bands after the D-band frequency reduction, and provide support for the evolution of 5G network. Secondly, in response to the goal of green network and cost reduction and efficiency improvement, the current room split appears in the low utilization rate and multiple load frequency scenarios, which accordingly increases the daily maintenance, cost and other expenditures. The common coverage cell identification method in the embodiments of the present specification can be used to ensure that the capacity and coverage meet the basic requirements, and then the network load frequency is adjusted, so as to reduce the device energy consumption. On the other hand, in the large room split scenario, based on the common coverage identification method in the embodiments of the present specification, accurate basis can be provided for room split load balancing, overlapping coverage and other optimization schemes, which is beneficial to improve the frequency band utilization and improve the network quality.
