Abstract
Description
Technical Field
[0001] The embodiments of the present application relate to the field of communication technology, and in particular, to a cell management method, a base station, and a storage medium. Background Art
[0002] The coverage solution for drone terminals mainly utilizes existing ground base station equipment and adjusts the mechanical and electrical tilt angles of base station antennas to achieve ground coverage while also taking low-altitude coverage into consideration. Main lobe coverage is basically not used.
[0003] At present, there are some problems with the coverage of drone terminals. On the one hand, the relationship between high-altitude neighboring cells is complex and difficult to plan in an orderly manner. Specifically, at lower altitudes, the optimal cell for drone terminals to reside presents a more regular honeycomb-shaped coverage. At higher altitudes, affected by antenna side lobes, etc., the optimal cell for drone terminals to reside may no longer be the cell closest to the drone terminal, and the association pattern with the ground cell becomes fragmented, resulting in complex neighboring cell relationships that are difficult to plan in an orderly manner.

[0056] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.
[0057] The following will specifically describe the technical solution of the present application and how the technical solution of the present application solves the above technical problems through embodiments and in conjunction with the accompanying drawings. The following embodiments may be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments.
[0058] In addition, the technical solutions described in the embodiments of the present application can be combined arbitrarily without conflict.
[0059] An embodiment of the present application provides a cell management method, which is implemented through a base station. Figure 1 A flowchart of a cell management method provided in an embodiment of the present application is shown in FIG. Figure 1 As shown, in the embodiment of the present application, the cell management method mainly includes the following steps:
[0060] S101. Perform neighbor cell switching and / or neighbor cell updating based on a neighbor cell selection index associated with the drone terminal.
[0061] In an embodiment of the present application, the base station can perform neighbor cell switching and / or neighbor cell update based on the neighbor cell selection indicator associated with the drone terminal.
[0062] In the embodiment of the present application, the neighboring cell selection index includes but is not limited to: dedicated bearer information of the drone terminal, coverage height of the optional cell reported by the drone terminal, and other information. Among them, the dedicated bearer information of the drone terminal can be used for neighboring cell switching, and the coverage height of the optional cell reported by the drone terminal can be updated with the neighboring cell, which are described in detail below.
[0063] In an embodiment of the present application, the neighbor cell selection index includes: dedicated bearer information of the UAV terminal. The base station performs neighbor cell switching based on the neighbor cell selection index associated with the UAV terminal, including: obtaining a list of cells that meet the switching conditions from the measurement report reported by the UAV terminal; selecting a target cell from the neighbor cell list based on the cell list and the dedicated bearer information; and triggering the UAV terminal to initiate a cell switch to the target cell.
[0064] It should be noted that in an embodiment of the present application, the core network can identify the drone terminal and establish a dedicated bearer for the drone terminal, and the base station obtains the dedicated bearer information of the drone terminal through the core network.
[0065] It can be understood that in an embodiment of the present application, the base station can communicate and interact with different terminal devices, and receive measurement reports reported by different terminal devices, which include drone terminals. When the base station receives the measurement report, it can determine whether the received measurement report is reported by the drone terminal.
[0066] In an embodiment of the present application, the base station can establish a mapping relationship between the terminal type information of the drone terminal or the 5G service quality indication (5G QoS Indicator, 5QI) information of the dedicated bearer and the measurement identifier of the drone terminal; accordingly, the base station determines whether the received measurement report is reported by the drone terminal, including: for the received measurement report, when there is a mapping relationship between the carried measurement identifier and the terminal type information or 5QI information of the drone terminal, it is determined that it is reported by the drone terminal.
[0067] It should be noted that in the embodiments of the present application, the base station can identify the drone terminal based on the information and behavioral characteristics reported by the drone terminal and determine the terminal type information. In addition, the 5QI information dedicated to the drone terminal can also be obtained through the core network. The specific method of obtaining this information is not limited in the embodiments of the present application.
[0068] It can be understood that in an embodiment of the present application, the base station can pre-establish a mapping relationship between the terminal type information or 5QI information of the drone terminal and the measurement identifier of the drone terminal, and the measurement report carries the measurement identifier of the terminal device that reports it. Based on this, the base station can determine whether the measurement report is reported by the drone terminal by identifying whether the measurement identifier carried in the measurement report is mapped to the terminal type information or 5QI information of the drone terminal.
[0069] In an embodiment of the present application, the base station can select a cell from the neighboring cell list and establish a mapping relationship with the terminal type information or 5QI information of one or more drone terminals; the base station selects a target cell from the neighboring cell list based on the cell list and the dedicated bearer information, including: obtaining the terminal type information or 5QI information of the drone terminal based on the dedicated bearer information; wherein the dedicated bearer information corresponds to the terminal type information or 5QI information of the drone terminal; from the neighboring cell list, retrieve the cell included in the cell list and having a mapping relationship with the terminal type information or 5QI information of the drone terminal; when at least one cell is retrieved, select the cell with the highest signal strength or signal quality from at least one cell to determine it as the target cell; when no cell is retrieved, select the cell with the highest signal strength or signal quality from the cell list to determine it as the target cell.
[0070] In an embodiment of the present application, the base station selects a cell from a neighboring cell list and establishes a mapping relationship with the terminal type information or 5QI information of one or more drone terminals, including: for each drone terminal, based on the frequency or probability of the cell appearing in the historical measurement report, the height of the cell base station, and at least one of the coverage height of the cell base station, a cell is selected from the neighboring cell list to establish a mapping relationship with the terminal type information or 5QI information.
[0071] It can be understood that in an embodiment of the present application, whether a certain cell in the neighboring cell list maps the terminal type information or 5QI information of a certain drone terminal can be determined based on the frequency or probability of the cell appearing in the historical measurement report of the drone terminal, the height of the cell base station, the height range that the cell base station needs to cover, and other information. Specifically, if the frequency or probability of the cell appearing in the historical measurement report of the drone terminal is higher than a certain threshold, or the height of the cell base station is higher than a certain threshold, or the height range that the cell base station needs to cover is higher than a certain threshold, then the mapping of the terminal type information or 5QI information of the cell to the drone terminal is added.
[0072] Figure 2 A schematic diagram of an exemplary neighbor cell handover scenario provided in an embodiment of the present application. Figure 2As shown, when the UAV terminal moves from cell 1 to cell 3, the base station can enable the UAV terminal to initiate switching to cell 3 based on the above-mentioned neighboring cell switching method.
[0073] It can be understood that in the embodiments of the present application, by presetting the 5QI information or terminal type information corresponding to the drone-specific bearer information in the neighboring cell list, and by mapping the measurement identifier in the measurement report reported by the drone terminal with the 5QI information or terminal type information, the drone terminal can be switched accurately, reducing unnecessary frequent switching.
[0074] In the embodiments of the present application, the coverage requirements of the drone terminal may involve different altitude ranges to provide corresponding services. Figure 3 As shown, the UAV terminal moves through different cells. Since different cells can correspond to different coverage heights, based on this, the base station can update the neighboring cell list based on the coverage height to achieve orderly planning of neighboring cells to support neighboring cell switching, which is described in detail below.
[0075] In an embodiment of the present application, the neighboring cell selection index includes: the coverage height of the optional cell reported by the drone terminal, and the optional cell is not included in the neighboring cell list of the base station; the base station updates the neighboring cell based on the neighboring cell selection index associated with the drone terminal, including: if the coverage height of the optional cell is higher than the coverage height of the service cell currently selected by the base station, then based on the height relationship between the coverage height of the optional cell and the coverage height of the first cell, the neighboring cell list is updated; if the coverage height of the optional cell is lower than the coverage height of the service cell, then based on the height relationship between the coverage height of the optional cell and the coverage height of the second cell, the neighboring cell list is updated; if the coverage height of the optional cell is equal to the coverage height of the service cell, the optional cell is added to the neighboring cell list; wherein the first cell is the cell with the highest height in the neighboring cell list; and the second cell is the cell with the lowest height in the neighboring cell list.
[0076] It should be noted that in an embodiment of the present application, the base station can identify the optional cell from the measurement report reported by the UAV terminal, and send a height request for the optional cell to the UAV terminal, thereby receiving the coverage height of the optional cell sent by the UAV terminal in response to the height request, and then performing neighboring cell update based on the coverage height of the optional cell.
[0077] It is understandable that in the embodiment of the present application, the optional cell is actually an unknown cell identified by the base station in the measurement report reported by the drone terminal, that is, the base station's neighbor cell list does not include the cell. The specific optional cell is not limited in the embodiment of the present application.
[0078] In an embodiment of the present application, the base station updates the neighboring cell list based on the height relationship between the coverage height of the optional cell and the coverage height of the first cell, including: if the coverage height of the optional cell is lower than the coverage height of the first cell, the optional cell is added to the neighboring cell list and the first cell is deleted; if the coverage height of the optional cell is higher than the coverage height of the first cell, it is prohibited to add the optional cell to the neighboring cell list; if the coverage height of the optional cell is equal to the coverage height of the first cell, then if the reporting number of the optional cell is higher than the first threshold value, the optional cell is added to the neighboring cell list.
[0079] In an embodiment of the present application, the base station updates the neighboring cell list based on the height relationship between the coverage height of the optional cell and the coverage height of the second cell, including: if the coverage height of the optional cell is higher than the coverage height of the second cell, the optional cell is added to the neighboring cell list and the second cell is deleted; if the coverage height of the optional cell is lower than the coverage height of the second cell, it is prohibited to add the optional cell to the neighboring cell list; if the coverage height of the optional cell is equal to the coverage height of the second cell, then if the reporting number of the optional cell is higher than the second threshold value, the optional cell is added to the neighboring cell list.
[0080] It can be understood that in the embodiment of the present application, the base station updates the neighbor cell list in the above manner, with the aim of making the coverage height of each cell in the neighbor cell list as close as possible to the coverage height of the currently selected service cell, thereby achieving orderly planning of the neighbor cells. In this way, when switching cells, it is more likely to select a cell suitable for the drone terminal from the neighbor cell list, and it can also avoid the problem of excessive differences in coverage heights between cells, which may lead to switching failures during cell switching.
