Description

Technical Field

[0001] The present application relates to the field of communication technology, and in particular to a method for determining a problem cell, an electronic device, and a storage medium. Background Art

[0002] With the rapid iteration of communication technology, the cost burden faced by operators in the construction and maintenance of base stations is increasing. At the same time, there is overlap between base stations built by different operators, resulting in a waste of resources. In this context, the co-construction and sharing solution that can achieve base station resource sharing has gradually become a new way for operators to seek development and innovation.

[0003] In the scenario of co-construction and sharing, if there are dense non-shared base stations around the shared base station, the shared users in the cell under the shared base station may be subject to co-frequency interference from the non-shared base station, resulting in poor service perception of the shared users and even service disconnection and voice drop. Therefore, how to identify these cells that are susceptible to interference is an urgent problem to be solved. Summary of the invention

[0004] The present application provides a method for determining a problem cell, an electronic device, and a storage medium, which can accurately evaluate and locate the problem cell so as to carry out subsequent network optimization work and improve network quality.

[0005] In a first aspect, the present application provides a method for determining a problem cell, the method comprising: determining a first type of base station around a shared base station, the first type of base station is a base station that does not have a sharing function turned on and has the same frequency as the shared base station. Determine the base stations that meet the dense conditions among the first type of base stations as potential interfering base stations. Determine the potential disturbed base stations around the potential interfering base station based on the distance, the potential disturbed base station is a base station that has a sharing function turned on. Based on the measurement report, determine the degree of interference of each cell under the potential disturbed base station. Determine that the cell whose degree of interference is greater than a preset threshold is a problem cell.

[0006] The technical solution provided by the present application brings at least the following beneficial effects: the present application determines the first type of base stations around the shared base station, and selects the base stations that meet the dense conditions from the first type of base stations as potential interfering base stations. Furthermore, the potential disturbed base stations around the potential interfering base station are determined. Since the potential disturbed base station is on the same frequency as the potential interfering base station and is close to the potential interfering base station, and the sharing function is not enabled for the potential interfering base station, the shared users under the potential disturbed base station are susceptible to the same-frequency interference of the potential interfering base station during movement, resulting in a deterioration in service perception capability. After determining the potential disturbed base station, the present application determines the degree of interference of each cell under the potential disturbed base station based on the measurement report, and then accurately determines the problem cell based on the degree of interference, so as to guide the operation and maintenance personnel to carry out interference troubleshooting and network optimization work in the high-interference area, and ensure the network performance and service perception of all users of the shared network.

[0007] A possible implementation method is to determine the degree of interference of each cell under a potentially disturbed base station based on a measurement report. The method also includes: for a target cell, determining the degree of interference of the target cell based on a measurement report of the target cell and a measurement report of a neighboring cell; the target cell is any cell under a potentially disturbed base station; and the neighboring cell is a cell adjacent to the target cell under a potentially interfering base station.

[0008] Another possible implementation method is to determine the degree of interference of the target cell based on the measurement report of the target cell and the measurement report of the neighboring cell, specifically including: determining the number of first sampling points, where the first sampling points are sampling points reported by shared users that meet the network quality conditions. Determining the number of second sampling points reported by all shared users in the target cell. Determining the ratio of the number of first sampling points to the number of second sampling points as the degree of interference of the target cell.

[0009] In another possible implementation, the network quality condition includes: a reference signal receiving power (RSRP) of the target cell is greater than or equal to a first threshold, and a difference between the RSRP of the neighboring cell and the target cell is less than or equal to a second threshold.

[0010] In another possible implementation method, the dense condition includes: if there are a preset number of first-class base stations within a range with the first-class base station as the center and the preset distance as the center, they are determined as potential interfering base stations; the preset distance is determined according to the type of deployment scenario in which the base station is located.

[0011] Another possible implementation method is to determine the area to be optimized based on the interference degree, the number of problem cells and the total number of cells. The interference source of the problem cell in the area to be optimized is determined with the interference degree as the priority. The network optimization of the interference source includes at least one of the following: enabling sharing, RF optimization, power reduction, and heterogeneous frequency networking.

[0012] Another possible implementation method is to determine the interference source of the problem cell in the area to be optimized. Specifically, it includes: determining the number of third sampling points of the neighboring cell; the third sampling point is the sampling point reported by the shared user in the neighboring cell around the problem cell that meets the network quality conditions; determining the number of fourth sampling points; the fourth sampling point is the sampling point reported by the shared user in all neighboring cells around the problem cell that meets the network quality conditions; determining that the ratio of the third sampling point number to the fourth sampling point number is greater than or equal to the third threshold; determining that the neighboring cell is the interference source.

[0015] In one possible implementation method, the determination module is specifically used to determine the degree of interference of the target cell based on the measurement report of the target cell and the measurement report of the neighboring cell; the target cell is any cell under the potentially disturbed base station; the neighboring cell is a cell adjacent to the target cell under the potentially interfering base station.

[0037] 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 only part of the embodiments of the present application, not 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.

[0038] It should be noted that, in the embodiments of the present application, words such as "exemplarily" or "for example" are used to indicate examples, illustrations or descriptions. Any embodiment or design described as "exemplarily" or "for example" in the embodiments of the present application should not be interpreted as being more preferred or more advantageous than other embodiments or designs. Specifically, the use of words such as "exemplarily" or "for example" is intended to present related concepts in a specific way.

[0039] In order to facilitate the clear description of the technical solutions of the embodiments of the present application, in the embodiments of the present application, the words "first", "second", etc. are used to distinguish the same items or similar items with basically the same functions and effects. Those skilled in the art can understand that the words "first", "second", etc. are not limiting the quantity and execution order.

[0040] The technical terms involved in the embodiments of the present application are explained below:

[0041] Co-construction and sharing: In the field of communication technology, it refers to a cooperative plan in which all parties involved in the sharing participate in the construction and jointly allocate resources to improve resource utilization and improve network quality.

[0042] Interleaved base station: refers to the phenomenon in which base stations built by different operators are cross-deployed in a region in mobile communications. This layout method helps to achieve universal coverage of the target area. In addition, the interleaved unshared base station described in this application refers to an interleaved base station that is built by one operator but not shared in a co-construction and sharing scenario.

[0043] With the rapid development of 5G and 4G technologies, the electronic communications industry has ushered in unprecedented changes. Traditional base station construction solutions can no longer meet the needs of the development of communication technology due to the high construction and operation costs. In order to improve network coverage and quickly build large-scale communication networks, operators have begun to choose a new development strategy - co-construction and sharing.

[0044] The sharing and co-construction scheme includes basic resource sharing, wireless network sharing, wireless + core network sharing, cross-network roaming sharing, virtual operators, etc. The first operator and the second operator mainly adopt the wireless network sharing scheme, that is, the core network and service layer of each party are independent, and sharing is realized in the access network part. Figure 1 As shown, various implementation methods of the co-construction and sharing solution are evaluated based on controllability and capital cost savings.

[0045] Basic resource sharing. This mainly includes infrastructure such as base station sites, towers, indoor distribution systems, and supporting systems such as computer rooms and power supplies. Because this type of solution only shares basic resources, operators have the greatest control over sharing, but also the least cost savings.

[0046] Wireless network sharing solution. Wireless network sharing (multi-operator core network, MOCN) is a networking method that shares wireless access networks and has an independent core network side. The specific implementation of wireless network sharing is to broadcast and share the public land mobile network (PLMN) of each operator on the wireless side, allowing users of all sharing parties to access the wireless network at the same time, and then the wireless base station identifies the users and services of all parties and correctly routes them to their respective core networks.

[0047] like Figure 2As shown in the figure, it is the reference architecture of 3G MOCN, where 201 is the core network (CN) of operator A, 202 is the core network of operator B, 203 is the core network of operator C, and 204 is the radio access network (RAN), including the radio network controller (RNC) and multiple base stations. A physical RNC will be divided into multiple logical RNCs and belong to different operators respectively. Each logical RNC is connected to the core network of the corresponding operator, and the logical RNC will control the base station to broadcast the PLMN of the corresponding operator.

[0048] like Figure 3 As shown in the figure, it is the reference architecture of 4G MOCN, where 301 is the core network of operator A, 302 is the core network of operator B, and the core network includes the mobility management entity (MME), serving gateway (SGW), and packet data network gateway (PGW). RAN includes 303 is the evolved node B (eNB), 304 is the PLMN exclusively used by operator A, 306 is the PLMN exclusively used by operator B, and 305 is the PLMN shared by operator A and operator B. The core networks of different operators are connected to RAN through MME and SGW.

[0049] like Figure 4 As shown in the figure, it is the reference architecture of 5G MOCN, where 401 is the core network of operator A, 402 is the core network of operator B, and the core network includes a set of network function units (NF(s)); in the RAN part, 403 is the next generation Node B (gNB), 404 is the PLMN exclusively used by operator A, 406 is the PLMN exclusively used by operator B, and 405 is the PLMN shared by operators A and B. The core networks of different operators are connected to RAN through FN(s).

[0050] Wireless network sharing solutions are divided into independent carriers and shared carriers. Independent carriers refer to sharing parties using different carriers, broadcasting their own PLMNs, and guiding their own users to access. The base station can identify and correctly route users and services of all parties based on the cell or PLMN.

[0051] Shared carrier in wireless network sharing means that all parties use the same carrier, broadcast the PLMN of each party at the same time, and guide users of all parties to access at the same time. The base station identifies users and services of all parties based on the PLMN and correctly routes them.

[0052] like Figure 5 The difference between independent carriers and shared carriers in the wireless network sharing solution shown in the figure. Among them, 501 is the core network of operator A, 502 is the core network of operator B, 503 is the independent carrier mode, 504 is the 5GF1 frequency band, 505 is the 5GF2 frequency band, 506 is the shared carrier mode, and 507 is the 5GF1 frequency band. In the independent carrier mode, operators A and B use different frequency bands for broadcasting in the access network, and in the shared carrier mode, they use the same frequency band for broadcasting.

[0053] Wireless + partial core network sharing. This means that operators share not only wireless access networks but also some core network resources, such as gateways and billing systems. Because this type of solution involves core network sharing, it can further reduce construction and maintenance costs, but at the same time, this solution requires a higher level of technology and complex network architecture support, so the controllability of sharing is not high.

[0054] Inter-network roaming sharing. This means that operators establish inter-network roaming agreements, allowing users to access other operators' networks when they do not have access to their own network. This solution can make full use of existing network resources and is also the most basic co-construction and sharing solution.

[0055] Virtual operators. Refers to new telecom operators that do not have their own telecom network facilities, but rely on renting network resources from traditional telecom operators to carry out telecom business. Because they do not have base station resources, their costs are the lowest, but at the same time, they also have the lowest sharing controllability.

[0056] In the wireless network sharing solution of the shared carrier mode, if there are densely populated non-shared base stations around the shared base station, the shared users in the cell under the shared base station may be subject to co-frequency interference from the adjacent cells under the non-shared base stations of the contractor, resulting in poor service perception of the shared users and even service disconnection and voice drop.

[0057] like Figure 6 As shown in the figure, there are three co-frequency and adjacent base stations, 601 is the contractor's non-shared F1 frequency 5G base station, 602 and 603 are shared F1 frequency 5G base stations. In this scenario, the mobile communication path of the shared user may be transferred to the 601 base station, but because the 601 base station is not shared, it will prevent the shared user from moving, resulting in the loss of the shared user's signal. That is, the 601 base station will cause co-frequency interference to the shared user.

[0058] Based on this, the present application determines the first type of base stations around the shared base station, and selects base stations that meet the dense conditions from the first type of base stations as potential interfering base stations. Further, the potential disturbed base stations around the potential interfering base station are determined. Since the potential disturbed base station is on the same frequency as the potential interfering base station and is close to the potential interfering base station, and the sharing function is not enabled for the potential interfering base station, the shared users under the potential disturbed base station are susceptible to the same-frequency interference of the potential interfering base station during movement, resulting in a deterioration in service perception capability. After determining the potential disturbed base station, the present application determines the degree of interference of each cell under the potential disturbed base station based on the measurement report, and then accurately determines the problem cell based on the degree of interference, so as to guide the operation and maintenance personnel to carry out interference troubleshooting and network optimization work in high-interference areas, and ensure the network performance and service perception of all users of the shared network.

[0059] The method for determining a problem cell provided in the present application can be applied to the server of an operator. The server mentioned here can be a server cluster composed of multiple servers, or a single server, or a computer. The embodiment of the present application does not limit the specific device form of the above-mentioned server.

[0060] In some embodiments, the operator's server is used to manage multiple base stations within the area, and can obtain relevant information of multiple base stations, such as location information, measurement reports reported by multiple terminals under the base station, etc., so as to implement the method for determining the problem cell in the embodiment of the present application.

[0061] Figure 7 A flowchart of a method for determining a problem cell provided in an embodiment of the present application is shown in FIG. Figure 7 As shown, the technical solution provided by the present application can be implemented by the above-mentioned server, and specifically includes the following steps:

[0062] Rules for determining the longitude and latitude of cell base stations: If the cells are co-frequency cells, the evolved node bidentity (eNB ID) is the same and the longitude and latitude of the cells do not exceed 50m, the longitude and latitude of the base stations to which these cells belong are the longitude and latitude of the midpoint or center of these cells; if the longitude and latitude of the cells exceed 50m, even if they have the same eNB ID, they are regarded as different base station coverage areas, that is, the longitude and latitude of the base station of the cell is the longitude and latitude of the cell itself. In order to better understand the technical solution of the present application, taking the wireless network shared by operators A and B as an example, the user problem cells under operator B are located and evaluated. Specifically, the problem cell can also be referred to as a co-frequency cell that is interfered with by operator A's non-shared base station.

[0063] S701: Determine a first type of base station around a shared base station. The first type of base station is a base station that does not have a sharing function enabled and has the same frequency as the shared base station.

[0064] The server determines a shared base station list based on the base station configuration data. For each shared base station in the list, the same-frequency base stations that are not shared by the contractor within a specific range around the shared base station are recorded as first-class base stations, and a first-class base station list is formed.

[0065] Specifically, a shared base station refers to a base station with the same frequency that is built by operator A or operator B and has the sharing function enabled. A shared user refers to a user of operator B who can use a base station built by operator A and has the sharing function enabled.

[0066] The first type of base station is a base station that does not have the sharing function enabled and has the same frequency as the shared base station, so it can also be called a same-frequency non-shared base station. Specifically, in the sharing scenario of operators A and B, the first type of base station can also be called a same-frequency base station built by operator A but without the sharing function enabled.

[0067] In some embodiments, the specific range used to retrieve the first type of base station can be determined differently according to the deployment scenario.

[0068] Exemplarily, when searching for the first type of base station, the relationship between the search scope and the deployment scenario is shown in Table 1 below:

[0069] Table 1

[0070]

[0071] In some embodiments, the same frequency includes 5G frequency bands F1, F2, F3 and 4G frequency bands F4, F5. This application does not limit the frequency band.

[0072] For example, operators A and B are implementing a co-construction and sharing solution in an urban area. Based on the base station configuration data, the 5G base stations in the F1 frequency band co-constructed and shared by operators A and B are counted within 200 meters. The 5G base stations in the F1 frequency band built by operator A but not shared are recorded as base stations with the same frequency but not shared, and a list of base stations with the same frequency but not shared is formed.

[0073] S702: Determine base stations that meet the dense condition among the first category of base stations as potential interfering base stations.

[0074] Specifically, the potential interfering base station may also be referred to as an inserted non-shared potential interfering same-frequency base station that affects the users of operator B.

[0075] In the first type base station list, with the first type base station as the center and the specific range as the radius, it is searched whether there are a preset number of first type base stations in the circular area, and if there are, they are recorded as potential interfering base stations. Exemplarily, the preset number is 3.

[0076] It should be understood that by setting dense conditions, areas with more potential interfering base stations can be quickly screened out. Accordingly, the shared users under the shared base stations around this area are most likely to be subject to co-channel interference.

[0077] In some embodiments, the dense condition can be expressed as: clustering the first-class base stations according to distance: with the first-class base station as the center and the preset distance as the radius, if there are a preset number of first-class base stations, then this first-class base station is recorded as a potential interfering base station affecting shared users; the preset distance is determined according to the deployment scenario type of the base station.

[0078] Exemplarily, when searching for potential interfering base stations, the relationship between the specific range and the deployment scenario is shown in Table 2 below:

[0079] Table 2

[0080]

[0081] For example, to further illustrate the example in step S701: cluster the 500-meter range around the same-frequency non-shared base station. If there are more than three same-frequency non-shared base stations in the area at the same time, they are recorded as potential interfering base stations that affect the users of operator B; after deduplication, a list of potential interfering base stations that affect the users of operator B is formed.

[0082] S703: Determine potential interfered base stations around the potential interfering base station based on the distance, where the potential interfered base station is a base station with a sharing function enabled.

[0083] Among them, the potential disturbed base station can also be called the potential disturbed base station that is not shared by the B operator's users;

[0084] With the potential interfering base station as the center, a circle is drawn according to the distance to search for shared base stations in the area within the circle. The retrieved shared base stations are recorded as potential interfered base stations. It should be understood that there are a large number of first-class base stations around the potential interfering base station. By retrieving shared base stations within the range of the potential interfering base station, the specific location of the shared user with the greatest possibility of being interfered with by the same frequency can be located.

[0085] Exemplarily, when retrieving potential interfering base stations, the distance may be determined according to the deployment scenario type, see Table 1.

[0086] For example, to further illustrate the example in step S702: take all the potentially interfering base stations in the potentially interfering base station list as the center of the circle and draw a circle with a radius of 200 meters. The base stations co-built and shared by operators A and B in the area within the circle are recorded as potential interfered base stations affecting users of operator B, and after deduplication, they are recorded as a list of potential interfered base stations affecting users of operator B.

[0087] S704: Determine the interference degree of each cell under the potentially disturbed base station based on the measurement report.

[0088] Statistics are collected for the target cell under the potentially disturbed base station, and the interference degree of the target cell is determined based on the measurement reports reported by the target cell shared users and the measurement reports of the neighboring cells under the potentially interfering base station adjacent to the target cell. By sampling and analyzing the measurement reports of the target cell and the neighboring cells, the network performance of the target cell and the neighboring cells can be understood, and then whether the target cell is subjected to the same-frequency interference of the neighboring cells can be analyzed, and the problem cell can be evaluated.

[0089] It should be noted that the measurement report is a measurement report (MR) sampling point reported by the shared user.

[0090] In some embodiments, the above S704 can be specifically implemented as follows: for the target cell, based on the measurement report of the target cell and the measurement report of the neighboring cell, determine the interference degree of the target cell; the target cell is any cell under the potentially disturbed base station; the neighboring cell is a cell adjacent to the target cell under the potentially interfering base station.

[0091] In some embodiments, the target cell may also be referred to as a primary serving cell. In some embodiments, based on the measurement report of the target cell and the measurement report of the neighboring cell, the interference degree of the target cell is determined, such as Figure 8 As shown, it can be specifically implemented as:

[0092] S7041. Determine the number of first sampling points; the first sampling points are sampling points reported by shared users that meet network quality conditions;

[0093] In some embodiments, the network quality condition is: the reference signal received power RSRP of the target cell is greater than or equal to a first threshold, and the difference between the RSRP of the neighboring cell and the target cell is less than or equal to a second threshold. Specifically, the sampling points that meet the network quality condition are also called the sampling points that are not shared by the neighboring cells and the target cell.

[0094] In some embodiments, the values ​​of the first threshold and the second threshold can be determined based on factors such as network quality and regional base station density, and the present application does not limit this. For example, the first threshold is -110 dBm (decibel relative to one milliwatt, dBm); the second threshold is 6 dBm;

[0095] S7042. Determine the number of second sampling points reported by all shared users in the target cell;

[0096] S7043: Determine a ratio of the number of first sampling points to the number of second sampling points as the degree of interference of the target cell.

[0097] For example, the calculation formula of the interference degree α of the target cell is as follows:

[0098]

[0099] in:

[0100] M means there are M neighboring cells around the target cell, X i represents any neighboring cell, (0≤i≤M);

[0101] X 目标 Indicates the target cell;

[0102] For example, the example in step S703 is further explained: the cells under all base stations in the list of potentially disturbed base stations affecting the shared users of operator B are counted, and in the MR sampling points reported by the shared users of operator B, if the RSRP of the target cell is greater than or equal to -110dBm, and there are neighboring cells under the potential interfering base station, and the RSRP difference between the target cell and the neighboring cell is less than or equal to 6dB. Then the sampling point is recorded as a sampling point that meets the quality condition. The number of sampling points that meet the quality condition in all neighboring cells is compared with the number of sampling points reported by all shared users of the target cell to obtain the degree of interference of the target cell.

[0103] S705, determining that a cell whose disturbance degree is greater than a preset threshold is a problem cell;

[0104] The disturbance degree of all cells under the potential interfering base station in step S104 is counted: if the disturbance degree of a cell exceeds a preset threshold, the cell is regarded as a problem cell.

[0105] In some embodiments, the problem cell is also referred to as a high interference area that affects the B operator's users.

[0106] In some embodiments, the preset threshold can be set according to different scenarios. For example, the preset threshold is 20%;

[0107] For example, to further illustrate the example in step S704: if the interference degree of the target cell under the potentially disturbed base station is greater than or equal to 20%, it is recorded as a problem cell.

[0108] In some embodiments, Fig. 9 As shown, after S705, the method for determining a problem cell provided by the present application further includes step S706, step S707 and step S708:

[0109] S706: Determine the area to be optimized according to the degree of disturbance, the number of problem cells and the total number of cells.

[0110] Under the potentially interfered base station, by checking whether the ratio of the number of problem cells to the number of all cells is greater than the threshold of the area to be optimized, the base station seriously affected by the potentially interfered base station can be determined and recorded as the area to be optimized. Specifically, the area to be optimized can also be called the high interference area that affects the users of operator B. For example,

[0111] In some embodiments, the threshold of the area to be optimized may be based on different scenarios. For example, the threshold of the area to be optimized is 10%.

[0112] For example, the example of step S705 is further explained: statistics are taken on the potential disturbed base stations with problem cells in the list of potential disturbed base stations affecting the shared users of operator B, and the number of problem cells of operator B under the base station is compared with the total number of cells under the base station. If the ratio is greater than or equal to 10%, the area is judged as an area to be optimized.

[0113] S707, determining interference sources of problem cells in the area to be optimized based on the interference degree as priority;

[0114] According to the degree of interference, the problem cells in the optimization area are checked for interference sources. By calculating the ratio of the number of sampling points that a neighboring cell in the problem cell causes to the problem cell and the number of sampling points that all neighboring cells cause to the problem cell, the degree of interference caused by the neighboring cell to the problem cell is calculated. The neighboring cells with a ratio higher than a certain value are recorded as interference sources. The ratio can be set according to different scenarios. For example, the ratio can be 30%.

[0115] In some embodiments, the interference source of the problem cell in the area to be optimized is determined based on the interference degree, such as Fig.10 As shown, it can be specifically implemented as:

[0116] S7071. Determine the number of third sampling points of the neighboring cell.

[0117] The third sampling point is a sampling point reported by a shared user that meets the network quality conditions in a neighboring cell around the problem cell;

[0118] S7072. Determine the number of fourth sampling points.

[0119] The fourth sampling point is a sampling point reported by shared users that meet network quality conditions in all neighboring cells around the problem cell;

[0120] S7073. Determine that the ratio of the number of the third sampling points to the number of the fourth sampling points is greater than or equal to a third threshold; determine that the neighboring cell is an interference source;

[0121] For example, the calculation formula of the interference impact degree β caused by the neighboring cell to the problem cell is as follows:

[0122]

[0123] Among them, M means that there are M neighboring cells around the problem cell, X i represents any neighboring cell, (0≤i≤M);

[0124] X 问题 Indicates problem area;

[0125] S708, network optimization of the interference source includes at least one of the following: enabling sharing, RF optimization, power reduction, and heterogeneous frequency networking. Specifically, the optimization of the interference source and the potential interfering base station where the interference source is located may include:

[0126] Enable sharing, request operator A to enable the sharing function of potential interfering base stations. RF optimization, optimize the radio frequency part of the wireless network, including antenna adjustment, power adjustment, frequency planning, etc., to improve network performance and reduce interference.

[0127] Power reduction refers to lowering the transmission power of potential interfering base stations, which can reduce interference to problem cells.

[0131] In addition, the present application also innovates a method for evaluating the impact of interference sources around problem cells. Based on this method, it is possible to accurately evaluate the interference source cells that have the most serious interference to the problem cells, thereby assisting in operation and maintenance optimization work.
