Description

Technical Field

[0001] The present application relates to the field of communication technology, and in particular to a BBU centralized processing method, device, equipment and medium for a 4G base station. Background Art

[0002] With the advancement of communications technology, the fourth-generation mobile communication technology (4G) is gradually transitioning to the fifth-generation mobile communication technology (5G). When operators operate multiple networks, how to reduce the profit gap between operators and equipment manufacturers, change the situation where operators' "increase in volume but not in revenue," and reduce network construction and operating costs are common challenges that all operators must address.

[0003] Currently, to address these issues, 5G networks primarily focus on centralized deployment of indoor baseband units (BBUs) within localized areas during network construction. This approach leverages existing equipment rooms, optical cables, power supplies, air conditioning, and other supporting infrastructure to improve BBU equipment, room utilization, and supporting facilities, saving on wireless network investment. This remote "zero-room" network construction model significantly reduces the need for equipment room facilities, particularly cooling systems like air conditioning, significantly contributing to energy savings and lowering operation and maintenance costs. Furthermore, through joint optimization of resource allocation and load balancing between sites and cells, overall system capacity and resource utilization are increased, improving user experience. However, due to the earlier deployment of 4G networks, manual verification of BBU-Remote Radio Unit (RRU) separation and transmission resource availability at the BBU centralization point is required before BBU centralization plans can be developed, resulting in slower development times.

[0069] The above drawings illustrate specific embodiments of the present disclosure, which will be described in more detail below. These drawings and textual descriptions are not intended to limit the scope of the present disclosure in any way, but rather to illustrate the concepts of the present disclosure to those skilled in the art by reference to specific embodiments. DETAILED DESCRIPTION

[0070] To make the purpose, technical solutions, and advantages of the embodiments of this application more clear, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0071] Before introducing the embodiments of the present application, the application background of the embodiments of the present application is first explained:

[0072] In existing technology, existing 4G BBU networks typically use a single BBU supporting three RRUs, with the BBUs and RRUs co-located in the same equipment room. Implementation of 4G BBU centralization requires manual verification of BBU-RRU separation and transmission resource availability at the BBU centralization point, hindering rapid BBU centralization planning.

[0073] Based on the above technical issues, when studying related fields, it was found that when building a 5G network, in order to save costs, 4G base stations and 5G base stations can be co-located. When a 4G base station and a 5G base station are co-located, the 4G base station and the 5G base station each have their own BBU and RRU, and share the same machine room, transmission, power supply, and roof resources, etc. That is, the 4G base station has a 4G BBU and 4GRRU, and the 5G base station has a 5G BBU and 5G RRU. In this way, when formulating a 4G BBU concentration plan, it is only necessary to determine whether the BBU-RRU is separated based on the location of the 4G BBU and the location of the 4G RRU. If they are not separated, the BBU concentration plan of the 4G base station is directly determined based on the BBU concentration plan of the 5G base station co-located with the 4G base station.

[0074] The technical solution of the present application is described in detail below through specific embodiments.

[0075] It should be noted that the following specific embodiments may be combined with each other, and the same or similar concepts or processes may not be described in detail in some embodiments.

[0076] Figure 1 This is a flow chart of a first embodiment of a BBU centralized processing method for a 4G base station provided in an embodiment of the present application. Figure 1 As shown, the BBU centralized processing method of the 4G base station is applied to electronic devices, which can be terminal devices such as mobile phones, computers, notebooks, etc., and can also be servers. The embodiments of this application do not specifically limit this. Among them, the BBU centralized processing method of the 4G base station can include the following steps:

[0077] S101. Determine the location of the 4G BBU and the location of the 4G RRU of the 4G base station according to 4G measurement reports uploaded by multiple 4G terminal devices to the 4G base station and GPS data of the 4G BBU of the 4G base station.

[0078] In this step, since one of the prerequisites for centralized deployment of the 4G BBU of the 4G base station is that the 4G BBU needs to be inseparable from the 4G RRU, and whether the 4G BBU is separated from the 4G RRU can be determined based on the position of the 4G BBU and the position of the 4G RRU, it is necessary to first determine the position of the 4G BBU and the position of the 4G RRU of the 4G base station.

[0079] In 4G networks, regardless of whether Long Term Evolution (LTE) Time Division Duplexing (TDD) or LTE Frequency Division Duplexing (FDD) is used, the 4G Base Unit (BBU) of a 4G base station must be equipped with a GPS antenna to generate Global Positioning System (GPS) data for the 4G BBU.

[0080] To elaborate, LTE TDD transmits and receives on the same frequency but at different times. Adjacent 4G base stations must maintain consistent uplink and downlink time slots, ensuring strict synchronization between base stations. Therefore, GPS antennas must be installed on 4G BBUs. While LTE FDD doesn't require inter-base station synchronization, implementing technologies like inter-cell interference coordination and multicast / multicast single-frequency networks also requires phase synchronization. Base stations also need to maintain synchronization, so 4G BBUs also require GPS antennas for time synchronization.

[0081] In one possible implementation, the location of the 4G BBU can be extracted from the GPS data of the 4G BBU, and the cluster centroid of each 4G cell of the 4G base station can be determined based on the 4G measurement report. The center point of the plane figure surrounded by all cluster centroids is determined as the location of the 4G RRU.

[0082] 4G measurement reports contain raw network data measured by users' 4G terminal devices, including received signal channel power (RSCP), transmit power, and user location information. Based on these reports, a geographical representation of a single 4G base station cell can be created on a map.

[0083] S102: Determine whether the 4G BBU and the 4G RRU are separated according to the position of the 4G BBU and the position of the 4G RRU.

[0084] In this step, when the 4G BBU and 4G RRU are not separated, they are relatively close to each other. However, when the 4G BBU and 4G RRU are separated, they are relatively far apart. Therefore, the distance between the 4G BBU and 4G RRU can be calculated based on the positions of the 4G BBU and the 4G RRU, and this distance can be compared with the first preset distance to determine whether the 4G BBU and 4G RRU are separated.

[0085] Optionally, the first preset distance may be set in advance according to actual conditions, and there is no specific limitation on this.

[0086] S103: If the 4G BBU and the 4G RRU are not separated, determine whether the 4G BBU and the 5G BBU of the 5G base station are co-located based on the 4G base station data and the 5G base station data.

[0087] In this step, if it is determined that the 4G BBU and 4G RRU are not separated, it means that the 4G BBU meets the conditions for centralized deployment. However, when formulating the centralized solution for the 4G BBU, this technical solution must be based on the centralized solution for the 5G BBU at the same site. Therefore, when it is determined that the 4G BBU and 4G RRU are not separated, it is necessary to further determine whether the 4G BBU exists with a 5G BBU at the same site.

[0088] Optionally, the 5G base station data may include 5G measurement reports uploaded by multiple 5G terminal devices to the 5G base station or GPS data of 5G BBUs. The 4G base station data may include the location of the 4G BBU or the cluster centroid of each 4G cell of the 4G base station.

[0089] Optionally, 5G base station data and 4G base station data may also include other content, which can be determined based on actual conditions. The embodiments of the present application do not impose specific restrictions on this.

[0090] It should be understood that the relevant definitions and principles of the 5G measurement report can refer to the relevant content of the 4G measurement report in S101, and will not be repeated here.

[0091] In one possible implementation, when a 4G base station and a 5G base station are co-located, the distance between the 5G BBU and the 4G BBU is relatively close, whereas when the 4G base station and the 5G base station are not co-located, the distance between the 5G BBU and the 4G BBU is relatively far. Therefore, the location of the 5G BBU can be extracted from the GPS data of the 5G BBU, and the distance between the 5G BBU and the 4G BBU can be calculated. Based on this distance and a third preset distance, it can be determined whether the 4G base station and the 5G base station are co-located.

[0092] Optionally, the third preset distance may be set in advance according to actual conditions, and there is no specific limitation on this.

[0093] In another possible implementation, when a 4G base station and a 5G base station are co-located, the distance between the 4G and 5G cells is relatively close; when they are not co-located, the distance between the 4G and 5G cells is relatively far. Therefore, the cluster centroid of each 5G cell of the 5G base station can be determined based on the 5G measurement report. Based on the distance between the cluster centroid of the 5G cell and the cluster centroid of the 4G cell, it can be determined whether the 4G and 5G base stations are co-located.

[0094] S104. If the base station is shared, generate the BBU concentration result of the 4G base station based on the BBU concentration result of the 5G base station.

[0095] In this step, the BBU centralization results for the 5G base station include the connection between the 5G base station and the equipment room, while the BBU centralization results for the 4G network include the connection between the 4G base station and the equipment room. In other words, if a 4G base station is determined to be co-located with a 5G base station, the 4G base station can be connected to the equipment room where the 5G base station's BBUs are centrally processed based on the 5G base station's BBU centralization results. This can also be understood as placing the 4G BBU in the aforementioned equipment room.

[0096] It should be understood that the BBU concentration result can also be understood as a BBU concentration solution.

[0097] The embodiment of the present application provides a BBU centralized processing method for a 4G base station. The electronic device determines the location of the 4G BBU and the 4G RRU of the 4G base station based on 4G measurement reports uploaded to the 4G base station by multiple 4G terminal devices and the GPS data of the 4G BBU of the 4G base station; determines whether the 4G BBU and the 4G RRU are separated based on the location of the 4G BBU and the location of the 4G RRU; if the 4G BBU and the 4G RRU are not separated, determines whether the 4G BBU and the 5G BBU of the 5G base station are co-located based on the 4G base station data and the 5G base station data; if they are co-located, generates a BBU concentration result for the 4G base station based on the BBU concentration result of the 5G base station. In this embodiment, the location of the 4G BBU and the 4G RRU is determined based on the 4G measurement report and the GPS data of the 4G BBU, and determines whether the 4G BBU and the 4G RRU are separated based on the location of the 4G BBU and the location of the 4G RRU, thereby replacing the manual determination process, increasing processing efficiency, and saving labor costs. At the same time, when the 4G BBU and 4G RRU are not separated, a centralized plan for the 4G BBU is formulated based on the centralized plan for the 5G BBU co-located with the 4G BBU. This eliminates the need to reconfirm whether the BBU concentration point has the ability to transmit resources, thereby speeding up the formulation of the 4G BBU centralized plan.

[0098] based on Figure 1 The illustrated embodiments specifically illustrate various possible implementations of the above embodiments. Figure 2 Schematic diagram of the flow of embodiment 2 of the BBU centralized processing method of the 4G base station provided in the embodiment of the present application. Figure 2 As shown, the BBU centralized processing method of the 4G base station may include the following steps:

[0099] S201 : Determine the location of the 4G BBU according to the GPS data of the 4G BBU.

[0100] S202 . Clustering is performed to obtain the cluster centroid of each 4G cell of the 4G base station according to the 4G measurement report.

[0101] In this step, each 4G base station has multiple 4G cells. Based on the 4G measurement reports, the 4G base stations can be geographically represented in multiple locations. After the geographical representation, clustering can be performed based on the grid of each 4G cell to determine the cluster centroid of each 4G cell.

[0102] In actual applications, each 4G base station generally has three 4G cells, and the 4G base station can be geographically presented in three directions based on the 4G measurement report.

[0103] Optionally, the clustering method can be the k-means++ clustering algorithm. Specifically, a grid under a 4G cell can be randomly selected as the first initial cluster centroid, the distance between each grid and the first initial cluster centroid is calculated, and the grid with the largest distance is selected as the new initial cluster centroid with probability. Further, the minimum distance between each grid and each existing initial cluster centroid is calculated again, and the grid with the largest distance among the minimum distances is selected as the new initial cluster centroid with probability. The above process is repeated until k (the number of grid clusters) initial cluster centroids are obtained and then stopped. Generally, a 4G cell grid outputs 1-2 cluster centroids, that is, the three 4G cells of a 4G base station can output 3-6 cluster centroids.

[0104] Figure 3 This is a schematic diagram of the cluster centroid of the 4G cell provided in the embodiment of this application. Figure 3 As shown in FIG, the 4G base station has three 4G cells, namely, 4G cell A, 4G cell B, and 4G cell C. The black dots in the figure are the determined cluster centroids of each 4G cell.

[0105] S203: Determine the location of the 4G RRU according to the cluster centroid of each 4G cell.

[0106] In this step, since the position of the 4G BBU and the position of the 4G RRU need to be determined before determining whether the 4G BBU and the 4G RRU are separated, the position of the 4G BBU and the position of the 4G RRU need to be further determined after the position of the 4G BBU is determined.

[0107] In one possible implementation, S203 may be implemented through steps (1) and (2):

[0108] Step (1): Connect each cluster centroid with adjacent cluster centroids to generate line segments or plane figures.

[0109] Optionally, when the number of cluster centroids is 2, the two cluster centroids may be connected by a straight line to generate a line segment; when the number of cluster centroids is greater than 2, adjacent cluster centroids may be connected by a straight line to generate a plane figure.

[0110] Step (2): determine the midpoint of the line segment or the center of the plane figure as the position of the 4G RRU.

[0111] Optionally, when the number of cluster centroids is 1, the location of the cluster centroid may be directly determined as the location of the 4G RRU.

[0112] Figure 4 This is a schematic diagram of the location of the 4G RRU provided in the embodiment of the present application. Figure 4 As shown in the figure, the five-pointed star is the determined position of the 4G RRU.

[0113] S204: Calculate the distance between the 4G BBU and the 4G RRU according to the position of the 4G BBU and the position of the 4G RRU.

[0114] In this step, since the determination of whether the 4G BBU and the 4G RRU are co-located is based on the distance between the 4G BBU and the 4G RRU, the distance between the 4G BBU and the 4G RRU needs to be calculated based on the positions of the 4G BBU and the 4G RRU.

[0115] In one possible implementation, assuming the latitude and longitude coordinates of the 4G BBU are (lon1, lat1) and the latitude and longitude coordinates of the 4G RRU are (lon2, lat2), the latitude and longitude angles can be converted to radians, and the converted values ​​are (mlon1, mlat1) and (mlon2, mlat2), respectively. The distance between the 4G BBU and 4G RRU can then be calculated using the following formula:

[0116]

[0117] Where S is the distance between the 4G BBU and the 4G RRU, a is the difference between lon1 and lon2, b is the difference between lat1 and lat2, and r is the radius of the earth.

[0118] S205: Determine whether the 4G BBU and the 4G RRU are separated based on the distance and the first preset distance.

[0119] In this step, the distance is compared with the first preset distance. If the distance is greater than the first preset distance, it is determined that the 4G BBU and 4G RRU are separated; if the distance is less than or equal to the first preset distance, it is determined that the 4G BBU and 4G RRU are not separated.

[0120] S206. If the 4G BBU and the 4G RRU are not separated, determine whether the 4G BBU and the 5G BBU of the 5G base station are co-located based on the 4G base station data and the 5G base station data.

[0121] In this step, when it is determined that the 4G BBU and 4G RRU are not separated, it is necessary to further determine whether the 4G BBU has a 5G BBU at the same site as it, so that the 4G BBU concentration solution can be quickly customized based on the concentration solution of the 5G BBU at the same site.

[0122] In one possible implementation, when the 5G base station data includes GPS data of the 5G BBU, S206 may be implemented through steps (3) and (4):

[0123] Step (3): If the 4G BBU and the 4G RRU are not separated, the location of the 5G BBU is determined based on the GPS data of the 5G BBU.

[0124] Step (4): determine whether the 4G BBU and the 5G BBU of the 5G base station are co-located based on the location of the 5G BBU and the location of the 4G BBU.

[0125] The distance between the 5G BBU and the 4G BBU can be calculated based on the position of the 5G BBU and the position of the 4G BBU. If the distance is greater than the third preset distance, it is determined that the 4G BBU and the 5G BBU are not co-located; if the distance is less than or equal to the third preset distance, it is determined that the 4G BBU and the 5G BBU are co-located.

[0126] In another possible implementation, when the 5G base station data includes a 5G measurement report, S206 may be implemented through steps (5) and (6):

[0127] Step (5): Determine the cluster centroid of each 5G cell of the 5G base station based on the 5G measurement report.

[0128] It should be understood that the implementation process and principle of step (5) can refer to the relevant content in S202 and will not be repeated here.

[0129] Step (6): determine whether the 4G BBU and the 5G BBU of the 5G base station are co-located based on the cluster centroid of each 5G cell of the 5G base station and the cluster centroid of each 4G cell of the 4G base station.

[0130] In step (6), the electronic device may calculate the distance between the cluster centroid of each 4G cell and the cluster centroid of each 5G cell. If each 4G cell has a 5G cell whose distance to the 4G cell is less than the second preset distance, it is determined that the 5G BBU and the 4G BBU are co-located. If any 4G cell does not have a 5G cell whose distance to the 4G cell is less than the second preset distance, it is determined that the 5G BBU and the 4G BBU are not co-located.

[0131] S207. If the base station is shared, generate the BBU concentration result of the 4G base station based on the BBU concentration result of the 5G base station.

[0132] It should be understood that the implementation method and principle of this step can refer to the relevant content in S104 and will not be repeated here.

[0133] Optionally, 4G base stations can refer to 5G base stations to carry out BBU integrated network planning, and 4G RRUs can use wavelength division or cascading to save transmission resources.

[0134] Figure 5 Schematic diagram of the BBU centralized solution provided in the embodiment of this application. Figure 5 As shown in the figure, 4G base stations and 5G base stations are co-located. Before developing a 4G BBU centralization plan, each 4G base station corresponds to a different equipment room, such as the first 4G base station corresponding to equipment room 2, the second 4G base station corresponding to equipment room 3, and the third 4G base station corresponding to equipment room 4. In other words, each 4G BBU is placed in a different equipment room. After determining that 4G base stations and 5G base stations are co-located, a 4G BBU centralization plan can be developed based on the 5G BBU centralization plan. In other words, all 4G BBUs are placed in the equipment room where the 5G BBUs are centralized (i.e., equipment room 1).

[0135] Figure 6 This is a flow chart of the third embodiment of the BBU centralized processing method for a 4G base station provided in the embodiment of the present application. Figure 6 As shown, the BBU centralized processing method of the 4G base station may include the following steps:

[0136] Step 1: Determine the location of the 4G BBU and 4G RRU of the 4G base station.

[0137] Step 2: Determine whether the 4G BBU and 4G RRU are separated.

[0138] Step 3: When the 4G BBU and 4G RRU are not separated, determine whether the 4G BBU and 5G BBU are co-located.

[0139] Step 4: When the 4G BBU and 5G BBU are co-located, plan the BBU centralization plan for the 4G base station based on the BBU centralization plan for the 5G base station.
