Detailed Description
The technical solutions in the embodiments of the present disclosure will be clearly and completely described below with reference to the drawings in the embodiments of the present disclosure, and it is obvious that the described embodiments are only a part of the embodiments of the present disclosure, and not all of the embodiments. The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way intended to limit the disclosure, its application, or uses. All other embodiments, which can be derived by a person skilled in the art from the embodiments disclosed herein without making any creative effort, shall fall within the protection scope of the present disclosure.
The present disclosure provides a dynamic control method for a remote radio unit, which is described below with reference to fig. 2.
Fig. 2 is a flowchart of some embodiments of a dynamic control method of a remote radio unit according to the present disclosure. As shown in fig. 2, the method of this embodiment includes: steps S202 to S208.
In step S202, the state of the base station is determined according to the traffic information of the base station within the preset time period.
The traffic information includes, for example: at least one of data throughput, number of connected users, number of activated users, and number of voice calls. The traffic information of the base station (or BBU) in the preset time period (for example, the previous 10 minutes) includes, for example: at least one of average data throughput, average number of connected users, average number of activated users and average number of voice calls in a preset time period.
In some embodiments, each item of traffic information of the base station in a preset time period is compared with a corresponding threshold, and the state of the base station is determined to be a busy state when one or more items of traffic information exceed the corresponding threshold. Or weighting each item of traffic information of the base station in a preset time period, comparing a weighting result with a corresponding weighting result threshold, and determining that the state of the base station is a busy state under the condition that the weighting result exceeds the corresponding weighting result threshold.
For example, the average data throughput of the base station in a preset time period is compared with a throughput threshold, and if the average data throughput is greater than the throughput threshold, the state of the base station is a busy state. In the case that there are multiple items of traffic information, it may be set that the base station is considered to be in a busy state as long as one item of traffic information exceeds a corresponding threshold, or it may be set that the base station is considered to be in a busy state when the number of items of traffic information exceeding the corresponding threshold is greater than a preset number of items. For another example, a corresponding weight may be set for each item of traffic information, each item of traffic information may be weighted, and then the status of the base station may be determined to be busy by comparing with a corresponding weighting result threshold.
In step S204, when the base station changes from the busy state to the idle state, the number of cells to be updated in the base station is determined according to the traffic information of the base station in the preset time period.
In some embodiments, the traffic information of the base station in the preset time period is compared with the traffic range corresponding to each preset traffic class, so as to determine the preset traffic class corresponding to the base station. And determining the number of the cells to be updated of the base station according to the preset service level corresponding to the base station.
And under the condition that the service volume information is one item, directly comparing the service volume information with the service volume range corresponding to each preset service volume grade. For example, the traffic information is data throughput, and the data throughput is compared with throughput ranges corresponding to respective preset traffic levels. When the traffic information is multiple items, the traffic range corresponding to each preset traffic class also includes multiple traffic ranges, and each item of traffic information needs to be compared with the corresponding traffic range. For example, the traffic information is data throughput and user connection number, and it is necessary to compare the data throughput with a throughput range corresponding to each preset traffic class, and compare the user connection number with a connection number range corresponding to each preset traffic class. Thereby determining the preset traffic level corresponding to the base station.
For example, the preset traffic level is divided into three levels, which may reflect the degree of idleness of the base station. And correspondingly storing different preset traffic levels and corresponding cell numbers. For example, the preset traffic level is level 1, which indicates that the base station is in the most idle state, and the number of corresponding cells may be configured to be 1, and the preset traffic level is level 2, which indicates that the base station is in the medium state, and the number of corresponding cells may be configured to be 2. And taking the cell number corresponding to the preset service volume grade as the cell number to be updated of the base station.
In step S206, the cell identifier of each RRU corresponding to the base station is changed according to the number of the cells to be updated, so that the number of different cells to which each changed RRU belongs is the same as the number of the cells to be updated.
And changing the cell identification of each RRU so as to combine the RRUs originally belonging to different cells into one cell, thereby achieving the purpose of reducing the number of the cells. Firstly, determining the number of RRUs in each changed cell, selecting an original cell, and changing the RRUs of other cells into cell identifiers of the original cell according to the distances between the RRUs of other cells and the RRUs of the original cell from small to large on the basis of each RRU of the original cell until the RRUs corresponding to the cell identifiers of the original cell reach the number of the RRUs in each changed cell.
In step S208, for each changed cell, a part of the RRUs is selected and turned off, and the remaining RRUs are increased in transmission power to cover the area range corresponding to the cell.
In some embodiments, determining the traffic information of each cell in a preset time period after the change according to the traffic information of each RRU in the preset time period before the change; determining the number of RRUs to be closed in each changed cell according to the service volume information of each changed cell in a preset time period; aiming at each changed cell, selecting a preset number of RRUs at intervals according to the number of the RRUs to be closed, closing the RRUs, and increasing the transmitting power of the rest RRUs to cover the area range corresponding to the cell; the total number of the RRUs to be closed is the number of the RRUs to be closed.
For example, the traffic information of each cell in a preset time period may be compared with each preset traffic range, and different preset traffic ranges correspond to the number of RRUs that are kept on. If the preset traffic volume range to which the traffic volume information of the cell in the preset time period belongs is determined, the number of the RRUs which are kept on can be determined, and then the number of the RRUs to be turned off is determined. The number of the RRUs kept on is determined according to the service volume which can be borne by each RRU. For example, the preset service volume range is 100-150 connection users, and each RRU bears at most 15 connection users to initiate a service request at the same time, the number of RRUs that remain on is 10.
In some embodiments, the number of RRUs to be closed in each cell after the change is determined according to the traffic information of each cell in a preset time period, the distance of each RRU, and the coverage area information of each RRU after the change. In order to ensure that after part of the RRUs are turned off, the remaining RRUs can also ensure coverage, and excessive RRUs cannot be turned off. The minimum number of the RRUs which are kept on can be determined based on the method, and further, the distance of each RRU and the coverage area information of each RRU determine whether the number of the RRUs which are kept on needs to be increased. For example, when RRUs are selected at intervals to be turned off, if the distance between the RRUs is 15 meters and the maximum coverage radius of the RRUs is 30 meters, after one RRU is turned off, the distance between two adjacent turned-on RRUs of the RRU is 30 meters, and the power of the two RRUs can be increased to ensure coverage.
The preset number of RRUs are selected at intervals to be closed, for example, 1 RRU is opened at intervals, and one or two RRUs are closed, that is, the closed preset number of RRUs are adjacent to the RRUs that are opened, so that the original coverage area of the closed RRUs can be covered after the transmission power is increased.
In some embodiments, the transmission power to be increased of each remaining RRU is determined according to the distance between the remaining RRUs and the coverage ranges corresponding to different transmission powers; and increasing the transmission power of each residual RRU according to the transmission power to be increased so as to cover the area range corresponding to the cell.
For example, according to the preset number of RRUs that are closed at intervals, based on the distance between the RRUs during initial deployment and the coverage areas corresponding to different transmission powers, transmission powers to be increased corresponding to different preset numbers may be preconfigured, for example, the preset number is 1, the transmission power to be increased is 50mW, the preset number is 2, the transmission power to be increased is 100mW, and then, the transmission power is increased for each remaining RRU according to the transmission power to be increased. Or calculating the transmission power to be increased of each remaining RRU according to the distance between the remaining RRUs and the coverage range corresponding to different transmission powers, and then increasing the transmission power of each remaining RRU according to the transmission power to be increased.
As shown in fig. 2, the method of this embodiment may further include: steps S210 to S214.
In step S210, when the base station changes from the idle state to the busy state, it is determined that the number of cells to be updated by the base station is the maximum number of cells.
All cells may be turned on in a busy state.
In step S212, the cell identifier of each RRU corresponding to the base station is changed according to the number of the largest cell, so that the number of different cells to which each RRU belongs after the change is the same as the number of the largest cells;
in step S214, turning on the turned-off RRUs for each changed cell, and adjusting each RRU to a preset transmission power.
The preset transmission power is greater than 0 and less than the transmission power of the rest RRUs in the idle state.
As shown in fig. 1, the 3-story building has 15 RRUs in total, and the 5G RRUs are disposed at an interval of 20 m. The coverage radius is 20m when the RRU is 250mW, and is 30m when the RRU is 500 mW. The base station is in an idle state, 1, 3 and 5 rows of RRUs are kept on, the RRUs are transmitted with 500mW power, 3 hubs and all RRUs are combined into 1 cell, 2 and 4 rows are closed, and the user coverage of the middle 2 and 4 rows can be ensured; in a busy state, 5 RRUs on each layer are started and transmitted with the power of 250mW, and meanwhile, the RRUs under each hub are combined into 1 cell, and 3 cells are counted, so that the power is reduced, and the user experience under high traffic is ensured. If the traffic is very low, such as at night, only 1 and 4 columns of RRUs can be started, and all RRUs are combined into 1 cell to ensure coverage.
In the above embodiment, it is determined that the base station is in an idle state or a busy state according to the traffic information of the base station in the preset time period, and when the base station is changed from the busy state to the idle state, the cell identifier corresponding to each RRU is changed, so as to reduce the number of cells of the base station, and a part of RRUs are selected and turned off for each changed cell, and the remaining RRUs are increased in transmission power to cover the area range corresponding to the cell. In the scheme of the embodiment, the base station reduces the number of cells in an idle state, so that resource consumption is reduced, partial RRUs are closed for each cell, resource consumption can be further reduced, the coverage range is ensured by improving the transmission power of the residual RRUs, the situation that a user cannot access the base station is avoided, and user experience is improved. And when the base station is busy again, the closed RRU is started, the number and the capacity of cells are increased, the telephone traffic is improved, and meanwhile, the coverage is not influenced. The scheme of the embodiment can improve the utilization efficiency of the RRU and reduce the working power consumption of the whole system. In addition, the method of the embodiment divides the state of the base station into an idle state and a busy state, and the base station can divide multiple traffic levels in the idle state, so that multiple dynamic adjustment schemes are realized, the dynamic control of the RRU is flexibly and effectively realized, and the resource utilization rate of the system is improved.
