Description

Technical Field

[0002] To meet the requirements of the rapid development of current wireless data services, the scales of 4G and 5G networks have grown rapidly. In the current environment of co - construction and sharing of base station sites, reasonably selecting shared sites has currently become a very effective means to rapidly improve network coverage ability, saving links such as new site selection and infrastructure supporting construction.

[0003] For the weak coverage areas of the network of the base stations of this network, the business quality deficiency in the weak coverage areas of the network of the base stations of this network can be compensated by selecting other network base stations that can be shared around, and the overall wireless service quality of the base stations of this network can be improved. Currently, a method of selecting shared base stations based on geographical topology has been proposed. Specifically, according to the geographical locations of other network base stations that can be shared around the weak coverage area of the network, combined with the geographical location of the base stations of this network, an area with a relatively large distance between the base stations of this network is found, and there are other network base stations that can be shared within this area, and shared base stations are selected accordingly.

[0004] However, this method does not consider the complexity of the wireless signal propagation path. Affected by factors such as occlusion by buildings and vegetation, wireless signals cannot propagate along the theoretical path. At the same time, the shared base stations are affected by factors such as station height and occlusion, and may not achieve the expected effect. Thus, the selected shared base stations cannot effectively compensate for the deficiencies in the weak coverage areas of the base stations of this network. Summary of the Invention

[0021] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application. The numbering of the drawings in this application is only used to distinguish the various steps in the scheme, and is not used to limit the execution order of the various steps. The specific execution order is subject to the description in the specification.

[0022] In order to solve the problems existing in the prior art, the present application embodiment provides a base station sharing method, such as Figure 1As shown, it includes the following steps 102 to 106.

[0023] Step 102, obtain a measurement report sent by a terminal in a cell under the jurisdiction of a target base station in a local area network, where the measurement report carries a first signal strength of the target base station and second signal strengths of multiple other network base stations outside the local area network of the target base station.

[0024] The target base station communicates based on the network of a first operator, and the other network base stations communicate based on a network different from the first operator. Relative to the other network base stations, the target base station can be called the local network base station. During the process of a terminal in a cell under the jurisdiction of the target base station using the target base station to perform services, it will continuously and periodically report or send to the target base station a measurement report (Measurement Report, MR) measured by the terminal. There are areas with weak network coverage in the cell under the jurisdiction of the target base station, and it is necessary to reasonably select other network base stations to be used as shared base stations of the target base station.

[0025] This method can be executed by a network element at a higher level above the target base station, or by a third-party system independent of the target base station.

[0026] The measurement report carries the signal strengths of the target base station measured by the terminal, the local network adjacent base stations of the local area network where the target base station is located, and multiple other network base stations outside the local area network. The structure of a single measurement report reported by each terminal of the obtained target base station is shown in Table 1 below, where the local network serving base station is the target base station, the local network adjacent base stations are the local network adjacent base stations of the local area network where the target base station is located, and the other network base stations are the other network base stations outside the local area network where the target base station is located.

[0027] Table 1

[0028] The number of local network adjacent base stations and the number of other network base stations included in the measurement report in Table 1 above are only examples, and their actual numbers are determined by the surrounding base station coverage of the location where the terminal is located. At the same time, the data items included in the measurement report only list the entries related to the base station sharing of the embodiments of the present application. Under normal network planning conditions, the frequency point and the Physical Cell Identifier (PCI) can uniquely determine a base station in the area where the terminal is located. Through this measurement report, not only can the signal strength of the local network base station be understood, but also the signal strengths of the other network base stations that can be shared can be understood at the same time. The data of the above MR is the basis for selecting shared base stations from multiple other network base stations.

[0029] Step 104: Based on the first signal strength and the second signal strength corresponding to the measurement report, determine the contribution degrees of the multiple other-network base stations when each of them serves as the shared base station of the target base station, where the contribution degree represents the degree to which the shared base station improves the network coverage ability of the target base station.

[0030] The measurement report includes the first signal strength of the target base station and the second signal strengths of multiple other-network base stations. When different other-network base stations serve as the shared base stations of the target base station, the degrees to which they can improve the network coverage ability of the target base station are different. There are areas with strong and weak network coverage in the cell area under the jurisdiction of the target base station. By reasonably selecting other-network base stations that can be shared, the weak coverage areas of the target base station's own network can be compensated, and the network coverage ability of the target base station can be quickly and effectively improved. In this step, based on the first signal strength and the second signal strength carried in the measurement report, the contribution degrees that can be provided by multiple other-network base stations when they serve as shared base stations are pre-evaluated to prepare for determining the final shared base stations.

[0031] Based on the solution provided in the above embodiment, optionally, in one embodiment, in the above step 102, the determining the contribution degrees of the multiple other-network base stations when each of them serves as the shared base station of the target base station based on the first signal strength and the second signal strength corresponding to the measurement report includes: counting the first measurement reports in the measurement reports sent by each terminal in the cell under the jurisdiction of the target base station, where the first signal strength carried in the first measurement report is lower than the preset strength threshold; counting the second measurement reports in each first measurement report, where the second signal strength of the target other-network base station in the second measurement report is higher than the preset strength threshold; calculating the ratio of the number of the second measurement reports to the number of the first measurement reports to obtain the contribution degree of the target other-network base station when it serves as the shared base station of the target base station.

[0032] In this embodiment, based on the measurement reports sent by each terminal in the cell under the jurisdiction of the target base station, the contribution degrees of each other-network base station when it serves as the shared base station of the target base station are determined. That is, the measurement reports generating traffic for the target base station are used as sampling points, and the shared base stations are evaluated from the dimension of the sampling points.

[0033] Let the set of base stations of the own network in a certain area be , and the number of base stations be , where the included base stations are , then . During a certain period of time, such as 24 hours, the total number of measurement reports collected by the target base station , that is, the number of sampling points is . Among them, a certain measurement report is , , and in this measurement report, the signal strength of the target base station is 。The base stations of other networks are identified by frequency points and PCI, and identifies a combination of a frequency point and PCI, that is, a base station that can be shared by other networks. All base stations of other networks are If so, the signal strength of the base station of other networks identified by the frequency and PCI combination in this measurement report is 。

[0034] In the embodiment of the present application, the target base station is a base station with a weak network coverage area. Compare the first signal strength in the measurement reports sent by each terminal in the cell under the jurisdiction of the target base station with the preset strength threshold to screen out the measurement reports corresponding to the weak network coverage area. The preset strength threshold is a value for judging whether the signal strength of the target base station meets the minimum requirement of the coverage level. For example, it can generally be taken as -110 dBm.

[0035] Based on the measurement reports of the screened weak network coverage area, count the measurement reports in which the second signal strength of the base stations of other networks is higher than the preset strength threshold. At this time, the screened measurement reports meet the conditions that the first signal strength of the target base station is lower than the preset strength threshold and the second signal strength of the base stations of other networks is higher than the preset strength threshold. This measurement report is an effective sampling point that can be used to determine the shared base station. Otherwise, the sampling point is an invalid gain point, thus avoiding invalid gain points.

[0036] In one embodiment, to ensure the stability of the shared base station, the signal strength of the base stations of other networks can be further limited to be higher than the preset strength threshold by a certain range. That is, add protective hysteresis For example, it can generally be taken as 3 dBm.

[0037] Taking the preset strength threshold as -110 dBm and the protective hysteresis as 3 dBm as an example, the signal strength of the target base station in the measurement report to be screened needs to be lower than -110 dBm, and the signal strength of the base stations of other networks needs to be higher than -107 dBm.

[0038] Specifically, define the function of the target base station corresponding to the effective sampling point as follows:

[0039] The function of the sampling point where the target base station has weak network coverage is as follows:

[0040] The effective sampling point function has the following conditions: 1. The signal strength of the base station in this network is less than or equal to the preset strength threshold; 2. The signal strength of the base station in other networks is greater than the preset strength threshold; 3. The difference between the signal strength of the base station in other networks and the signal strength of the base station in this network is greater than or equal to the protection hysteresis. If the above three conditions are met simultaneously, the output value of the effective sampling point function is 1, otherwise (others), the output value is 0. Thus, the effective sampling points that meet the above conditions can be counted out.

[0041] For the same base station in other networks, it may appear in different measurement reports. Then, through the above method, the effective sampling points corresponding to this base station in other networks can be obtained. After screening out the sampling points with weak network coverage corresponding to the first measurement report and the effective sampling points corresponding to this base station in other networks (corresponding to the second measurement report), calculate the ratio of the number of the second measurement report to the number of the first measurement report. This ratio can be used to represent the contribution degree of this base station in other networks as a shared base station for the target base station.

[0042] Base station in other networks As the target base station When it is a shared base station, for the target base station The formula for the contribution degree is defined as follows. The greater the contribution degree, the higher the degree to which the base station in other networks improves the network coverage ability of the target base station.

[0043]

[0044] The above embodiments evaluate the shared base station from the dimension of the sampling points where the target base station generates traffic. However, if there are a large number of measurement reports reported by a certain terminal with continuous large traffic, this individual performance will have a greater impact on the evaluation of the contribution degree of the base station in other networks as a shared base station, that is, the evaluation result of the contribution degree is easily affected by the measurement results of a small number of terminals with a high number of reported measurement reports.

[0045] Therefore, it can be supplemented from the user level, that is, from the dimension of different terminal devices, to exclude the interference caused by individual terminals.

[0046] Thus, in another embodiment, the measurement report further carries the user identifier of the terminal. Before determining the contribution degrees of the multiple other network base stations as the shared base stations of the target base station based on the first signal strength and the second signal strength corresponding to the measurement report, it further includes: classifying the measurement reports sent by the terminal based on the user identifiers of the terminals in the cell under the jurisdiction of the target base station to obtain a measurement report sequence corresponding to the same terminal; counting the fifth measurement reports in the measurement report sequence corresponding to the same terminal, where the first signal strength in the fifth measurement report is lower than a preset strength threshold; determining the terminals with weak network coverage in the cell under the jurisdiction of the target base station based on the ratio of the number of the fifth measurement reports to the number of the measurement report sequences; and determining the contribution degrees of the multiple other network base stations as the shared base stations of the target base station based on the first signal strength and the second signal strength corresponding to the measurement report, including: determining the contribution degrees of the multiple other network base stations as the shared base stations of the target base station based on the first signal strength and the second signal strength corresponding to the measurement reports of the terminals with weak network coverage.

[0047] In this embodiment, through the user identifier such as MmeUeS1apId existing in the measurement report, the S1 link establishment requests of individual terminals can be distinguished, and this user identifier can be used to approximately distinguish the traffic flows of the terminal within a period of time. Therefore, first, the measurement reports of all sampling point dimensions sent by the terminals of the target base station in the above embodiment are aggregated to the user dimension, and then the contribution degree evaluation is performed.

[0048] The specific method is as follows: The measurement reports reported by the terminals in the cell under the jurisdiction of the target base station can be regarded as sequences marked with different MmeUeS1apIds, and are classified with MmeUeS1apId as the index. Each measurement report sequence represents the sampling points of the user dimension corresponding to the same terminal.

[0049] For each measurement report sequence of the user dimension, respectively screen out the measurement reports in which the signal strength of the target base station is lower than the preset strength threshold, that is, count the number of measurement reports with weak network coverage in the measurement report sequence reported by the same terminal. Then, calculate the ratio of the number of measurement reports with weak network coverage to the number of measurement report sequences to obtain the proportion of the measurement reports with weak network coverage of the same terminal device in the entire measurement report sequence. If this ratio is greater than the preset quantity threshold, then determine the same terminal as the terminal with weak network coverage in the cell under the jurisdiction of the target base station. That is to say, the area where the terminal performs services is the area with weak network coverage of the target base station.

[0050] Through the above method, the terminals with weak network coverage corresponding to the cells under the jurisdiction of the target base station can be screened out, and further, by using the above method for screening effective sampling points, based on the effective sampling points corresponding to the measurement reports reported by the terminals with weak network coverage, and based on the corresponding first signal strength and second signal strength, the contribution degrees of multiple other network base stations as the shared base stations of the target base station are determined.

[0051] These terminals with weak network coverage are not terminals that continuously carry out large-scale services. Compared with the measurement reports reported by terminals that continuously carry out large-scale services, the measurement reports reported by terminals with weak network coverage can more comprehensively reflect the network coverage of the target base station, avoiding the interference caused by a large number of measurement reports reported by individual terminals to the evaluation of the contribution degree of other network base stations as shared base stations, and can improve the accuracy of contribution degree evaluation by combining effective sampling points from the user dimension.

[0052] For example, a preset quantity threshold is, for example, 5%, , where is the total number of terminals that meet the conditions, v represents the number of one terminal, and the defined formula is as follows:

[0053] The meanings of the variables in the above formula are the same as those defined in the functions of the corresponding effective sampling points and the sampling point function of weak network coverage in the above embodiments, but the range of sampling points (i.e., measurement reports) is limited to the terminals with weak network coverage. Thus, for a single terminal with weak network coverage, the other network base station for the target base station the defined contribution degree formula is as follows:

[0054] For all terminals with weak network coverage, the other network base station for the target base station the defined contribution degree formula is as follows:

[0055] That is, calculate the ratio of the sum of the contribution degrees corresponding to each terminal with weak network coverage of the other network base station to the number of terminals with weak network coverage. This ratio represents the contribution degree of the other network base station as the shared base station of the target base station .

[0056] The above two embodiments respectively describe how to determine the contribution degree of other network base stations as the shared base stations of the target base station from the sampling point dimension and the user dimension.

[0057] In yet another embodiment, the sampling point dimension and the user dimension corresponding to the above two embodiments may be combined for comprehensive evaluation to obtain the result of the contribution degree.

[0058] Optionally, determining the contribution degree when each of the multiple other network base stations serves as the shared base station of the target base station based on the first signal strength and the second signal strength corresponding to the measurement report includes: determining the contribution degree corresponding to the measurement reports sent by each terminal in the cell under the jurisdiction of the target base station and the contribution degree corresponding to the measurement reports sent by the terminals with weak network coverage, and determining the contribution degree when each of the multiple other network base stations serves as the shared base station of the target base station.

[0059] For example, set a weight factor , and calculate the comprehensive evaluation result between the contribution degrees determined corresponding to the sampling point dimension and the user dimension. It can be set according to the tendency of evaluating the number of measurement reports in the sampling point dimension or the number of terminals in the user dimension, or can also be directly set as a proportional weight of 0.5.

[0060] The comprehensive evaluation result of the contribution degree is expressed by the following formula:

[0061] Wherein, represents the contribution degree of the other network base station for the target base station considering both the sampling point dimension and the user dimension.

[0062] Step 106: Based on the contribution degree, determine the shared base station of the target base station among the multiple other network base stations.

[0063] For the case of selecting an other network base station as the shared base station of a single target base station, optionally, determining the shared base station of the target base station among the multiple other network base stations based on the contribution degree includes: sorting the contribution degrees of the multiple other network base stations corresponding to the target base station; and selecting at least one other network base station as the shared base station of the target base station in the order from high to low contribution degree.

[0064] For multiple other-network base stations recorded in the measurement report, the contribution degree of each other-network base station as the target base station can be calculated respectively based on the embodiments of the above steps 102 to 104. The greater the contribution degree, the higher the degree to which the other-network base station improves the network coverage ability of the target base station. Sort these contribution degrees in descending order, and then select the other-network base stations corresponding to the TOP N contribution degrees as the shared base stations of the target base station. The number of other-network base stations selected as the shared base stations is related to the weak network coverage area of the target base station and the contribution degrees of the other-network base stations. One or more other-network base stations can be selected according to the descending order of the contribution degrees as needed.

[0065] The above embodiments are for optimizing the selection of shared base stations for the weak network coverage area of a single target base station. However, in the optimization of the weak network coverage area, the overall coverage improvement is often carried out in units of local areas. Therefore, the above network optimization for a single target base station is extended to the regional scope.

[0066] For the case of selecting other-network base stations as the shared base stations of the entire regional network where the target base station is located, optionally, the regional network includes multiple target base stations, and the method further includes: summing the contribution degrees of the multiple other-network base stations corresponding to each target base station respectively and then sorting them; selecting at least one other-network base station as the shared base station of the multiple target base stations according to the descending order of the contribution degrees.

[0067] As described above, define the set of home-network base stations in a certain area as , the number of target base stations is , and the target base stations included therein are , then .

[0068] For all target base stations in this area, as a whole, calculate the contribution degrees corresponding to the sampling point dimension respectively according to the above steps for a single target base station and / or the contribution degrees corresponding to the user dimension .

[0069] For the contribution degrees that comprehensively consider the sampling point dimension and the user dimension, the calculated contribution degrees are as follows:

[0070] Wherein, represents the total contribution degree of the other-network base station corresponding to the multiple target base stations of the entire home-network base station set in the sampling point dimension, represents the total contribution degree of the other-network base station corresponding to the multiple target base stations of the entire home-network base station set in the user dimension.

[0071] For the network optimization of this area, perform sorting, and select at least one other network base station in descending order of contribution degree as the shared base station for this area, where .

[0072] Thus, evaluate the value of the base station to be shared from the perspective of improving the overall coverage gain of the area, accumulate the contribution degrees of the base stations to be shared to all the base stations of the local network in the area, so as to measure the effectiveness of sharing from the area perspective and further exert the benefits of building shared base stations.

[0073] Next, combined with Figure 2 , describe the base station sharing method of an embodiment of this application. As Figure 2 shown, it includes the following steps: Step 202, collect the measurement report MR based on the MR original file sent by the terminal; Step 204, parse the obtained measurement report MR to distinguish the measurement report in the sampling point dimension and the measurement report in the user dimension; Step 206, starting from the sampling point dimension, analyze the measurement report to obtain the contribution degrees when multiple other network base stations are respectively used as the shared base stations of the target base station, and determine the other network base stations as the shared base stations, and proceed to step 212; Step 208, starting from the user dimension, analyze the measurement report to obtain the contribution degrees when multiple other network base stations are respectively used as the shared base stations of the target base station, and determine the other network base stations as the shared base stations, and proceed to step 212; Step 210, starting from the sampling point dimension and the user dimension, integrally analyze the measurement report to obtain the contribution degrees when multiple other network base stations are respectively used as the shared base stations of the target base station, and determine the other network base stations as the shared base stations, and proceed to step 212; Step 212, recommend and output the other network base stations as the shared base stations.
