Description

Technical Field

[0001] This application relates to the field of communication technologies, and more specifically, to a method and a communication device for managing a remote electric tilt device.

Background Art

[0002] Due to the continuous evolution of network standards, communication networks have been able to support more and more frequency bands. For example, communication networks can support frequency bands such as 700 megahertz (MHz), 800 MHz, 900 MHz, 1800 MHz, 2100 MHz, 2600 MHz, and 3500 MHz. However, there is a problem that it is increasingly necessary to install more and more antennas on the antenna panel. As a result, the space limitation of the antenna panel becomes a bottleneck in the deployment of base stations.

[0003] In order to save the space of the antenna panel, currently, the concept of a multi-band antenna, that is, enabling one physical antenna to support multiple frequency bands, has been proposed. A multi-band antenna can save the space of the antenna panel, but this also poses challenges to the management of the remote electric tilt device of the multi-band antenna. For example, a method for accurately performing an electric tilt for a cell tilt corresponding to each frequency band supported by a multi-band antenna becomes a problem.

[0004] Currently, solutions for performing an electric tilt for a cell tilt in a multi-band antenna scenario are mainly implemented through manual means. This limits the applicability of the solution and also causes adjustment errors. Therefore, a method for improving the accuracy of performing an electric tilt for a cell tilt becomes an urgent technical problem to be solved.

Summary of the Invention

[0005] This application provides a method and communication apparatus for managing a remote electric tilt device to improve the accuracy of performing electric tilt on a cell tilt.

[0006] According to a first aspect, a method for managing a remote electric tilt device is provided. The method is applied to a first communication device, the first communication device manages at least one remote electric tilt device and at least two cells, and the method includes the steps of: generating first information, the first information being used to determine a first mapping table, where each mapping relationship in the first mapping table represents a correspondence between one remote electric tilt device and one or more cells; and transmitting the first information to a second communication device.

[0007] Specifically, each mapping relationship in the first mapping table may represent a correspondence between one remote electric tilt device and one or more cells, or each mapping relationship may represent a correspondence between the identification of one remote electric tilt device and the identification of one or more cells. In possible implementations, the identification of a remote electric tilt device is the serial number of the remote electric tilt device, the identification of a cell is the cell identification, and the serial number of one remote electric tilt device corresponds to the cell identification of one or more cells. Thus, each mapping relationship in the first mapping table may represent a correspondence between the serial number of one remote electric tilt device and the cell identification of one or more cells, and a remote electric tilt device may be associated with a cell.

[0008] The first communication device generates first information used to determine the first mapping table. In this application, the correspondence between remote electric tilt devices and cells managed by the first communication device can be automatically obtained, thereby eliminating manual user operation and improving the user experience. Furthermore, when the number of remote electric tilt devices and cells managed by the first communication device changes, the aforementioned solution also helps to obtain updated correspondences between the remote electric tilt devices and cells.

[0009] According to the aforementioned solution, this application can support the centralized management of remote electric tilt devices in a "what you see is what you get" manner. For example, when electric tilt is performed on a cell, the association relationship between the remote electric tilt device (or the serial number of the remote electric tilt device) and the cell (or the cell identification of the cell) may be directly displayed. For example, when an administrator wants to adjust the tilt of a cell, the administrator can set a cell tilt adjustment command. The first or second communication device can find the remote electric tilt device corresponding to the cell by using the first mapping table, and as a result, the tilt of the corresponding cell can be adjusted by using the remote electric tilt device.

[0010] Furthermore, the aforementioned technical solutions can improve the accuracy of performing electric tilt for cell tilt and avoid adjustment errors.

[0011] In a possible implementation, the first communication device supports at least two frequency bands, and the first information includes at least one of a first mapping table, a second mapping table, or a third mapping table. Each mapping relationship in the second mapping table indicates a correspondence between one remote electric tilt device and one frequency band, each mapping relationship in the third mapping table indicates a correspondence between one cell and one frequency band, and the first mapping table is determined based on the second and third mapping tables.

[0012] Specifically, each mapping relationship in the second mapping table representing a correspondence between one remote electric tilt device and one frequency band may represent a correspondence between the serial number of one remote electric tilt device and one frequency band. Therefore, each mapping relationship in the second mapping table may represent a correspondence between the serial number of one remote electric tilt device and one frequency band. Similarly, each mapping relationship in the third mapping table representing a correspondence between one cell and one frequency band may represent a correspondence between the cell identification of one cell and one frequency band. Therefore, each mapping relationship in the third mapping table may represent a correspondence between the cell identification of one cell and one frequency band.

[0013] Specifically, when the first information includes a second mapping table and a third mapping table, the second communication device can establish a correspondence between the remote electric tilt device managed by the first communication device and the cell based on the second and third mapping tables. Alternatively, when the first information includes one of the second and third mapping tables, the second communication device can establish a correspondence between the remote electric tilt device managed by the first communication device and the cell based on items included in the first information and other pre-configured items.

[0014] In this application, the association relationship between a remote electric tilt device managed by a first communication device and a cell can be associated by using an intermediate parameter, namely a frequency band.

[0015] In a possible implementation, the first information includes a second mapping table, and the step of generating the first information includes the step of receiving the second information from a third communication device, the second information being used to determine the correspondence between frequency bands and serial numbers of at least one remote electric tilt device, and the step of determining the second mapping table based on the second information.

[0016] Specifically, in this application, information exchange between a first communication device and a third communication device is supported to obtain second information used to determine a second mapping table, and the determined second mapping table is transmitted to the second communication device. Accordingly, the second communication device establishes an association relationship between the remote electric tilt device and the cell managed by the first communication device, based on the pre-configured third mapping table and the second mapping table transmitted by the first communication device, thereby performing accurate electric tilt of the cell tilt and avoiding adjustment errors of the cell tilt. Furthermore, when the number of remote electric tilt devices and cells managed by the first communication device changes, the above solution also helps to obtain an updated correspondence relationship between the remote electric tilt device and the cell.

[0017] In possible implementations, the second piece of information may indicate the frequency band and serial number of some or all of the remote electric tilt device, or the second piece of information may indicate the serial number of some or all of the remote electric tilt device.

[0018] In this way, the first communication device can determine, based on the information, the correspondence between the frequency band and the remote electric tilt device (or the serial number of the remote electric tilt device) managed by the first communication device.

[0019] In a possible implementation, the second information includes the serial numbers of some or all of the remote electric tilt devices, and the step of determining a second mapping table based on the second information includes determining a second mapping table based on the serial numbers of some or all of the remote electric tilt devices and a pre-configured correspondence between coloring numbers and frequency bands, wherein the serial number of one remote electric tilt device corresponds to one coloring number and one coloring number corresponds to one frequency band.

[0020] According to the aforementioned technical solution, the signaling overhead of the third communication device can be reduced, and the third communication device only feeds back the serial number of the remote electric tilt device to the first communication device.

[0021] In a possible implementation, the first information includes a third mapping table, and the step of generating the first information includes sending first request information to a terminal device, the terminal device being located in the anchor cell of at least two cells; receiving first feedback information from the terminal device, the first feedback information being a response to the first request information, the first feedback information including the respective frequency bands and cell identifications of at least two cells; and determining a third mapping table based on the frequency bands and cell identifications of each cell.

[0022] Specifically, in this application, information exchange between a first communication device and a terminal device is supported to determine a third mapping table and to obtain information regarding the frequency band and cell identification of each cell, and the determined third mapping table is transmitted to a second communication device. Accordingly, the second communication device establishes an association relationship between the remote electric tilt device managed by the first communication device and the cell, based on the pre-configured second mapping table and the third mapping table transmitted by the first communication device, in order to perform accurate electric tilt of the cell tilt and avoid adjustment errors of the cell tilt. Furthermore, when the number of remote electric tilt devices and cells managed by the first communication device changes, the above solution also helps to obtain an updated correspondence relationship between the remote electric tilt device and the cell.

The device may be installed on a terminal device, or may be used in combination with a terminal device.

In embodiments of this application, a chip system may include a chip, or a chip and other separate components.

[0105] Figure 1 is a diagram of application scenario 100 according to an embodiment of the present application. As shown in Figure 1, application scenario 100 includes a BBU module 110, an RRU module 120, a remote electrical tilt (RET) module 130, and an antenna panel 140. The BBU module 110 includes at least one BBU, e.g., BBU#111, BBU#112, and BBU#113. The RRU module 120 includes at least one RRU, e.g., RRU#121, RRU#122, and RRU#123. The remote electrical tilt module 130 includes at least two remote electrical tilt devices, e.g., RET device#131, RET device#132, and RET device#133. The antenna panel 140 includes at least two cells, for example, cell #141, cell #142, and cell #143 (or the coverage area of ​​the antenna panel 140 may be divided into at least two cells, or the antenna panel 140 may be configured to perform data transmission in at least two cells). The remote electric tilt device module 130 is configured to control the tilt of the antenna panel 140. In other words, the remote electric tilt device module 130 is configured to control the tilt of each cell corresponding to the antenna module 140, thereby affecting the coverage area of ​​each cell. Furthermore, the remote electric tilt device module 130 may be integrated (as shown in Figure 1) or it may be located externally and connected to the antenna panel 140. This is not limited to this. For illustrative purposes, the following example uses the remote electric tilt device module 130 integrated into the antenna panel 140.

[0106] Optionally, in the methods provided in this application, the BBU may be replaced with a DU for illustrative purposes, and the RRU may be replaced with an AAU, pRRU, RRH, or another radio frequency module.

[0107] Furthermore, each BBU within the BBU module 110 may support different standard communication networks separately. For example, BBU#111 supports LTE, BBU#112 supports NR, and BBU#113 supports FDD.

[0108] Specifically, the network device (e.g., base station) includes a BBU module 110 and an RRU module 120, and the antenna device includes a remote electric tilt device module 130 and an antenna panel 140. Optionally, the network device (e.g., base station) may also include a remote electric tilt device module 130 and an antenna panel 140. This is not limited to the present application.

[0109] In application scenario 100, BBUs, RRUs, RET devices, and cells are associated with each other (such association relationships may or may not have been learned before, and are not limited to this). For example, BBU#111 corresponds to RRU#121, RRU#121 corresponds to RET device#131, RET device#131 corresponds to cell#141, BBU#112 corresponds to RRU#122, RRU#122 corresponds to RET device#132, RET device#132 corresponds to cell#142, BBU#113 corresponds to RRU#123, RRU#123 corresponds to RET device#133, and RET device#133 corresponds to cell#143.

[0110] Application Scenarios 100 Please understand that the association relationships between BBU, RRU, RET devices, and cells shown are logical associations (indicated by the use of dashed lines) and not actual physical connections.

[0111] Specifically, the RRU module 120 may be connected to the antenna panel 140 via a radio frequency feeder, thereby enabling signal reception and transmission. For example, the antenna panel 140 includes an antenna interface standards group (AISG) interface, and the anchor RRU of the RRU module 120 (e.g., the anchor RRU is RRU#122) can establish a connection relationship with the remote electric tilt device module 130 through the AISG interface of the antenna panel 140 in order to control the tilt of each cell of the antenna panel 140 by using the remote electric tilt device module 130. There is no connection relationship between RRUs other than the anchor RRU in the RRU module 120 and the remote electric tilt device module 130. In other words, the user can control all RET devices in the remote electric tilt device module 130 only by using the anchor RRU in the RRU module 120. Optionally, the RRU module 120 This may include one or more anchor RRUs. One anchor RRU may be connected to one or more RET devices, and one RET device may be connected to one anchor RRU.

[0112] However, when the association relationships between the anchor RRU, RET device, and cell in application scenario 100 have not yet been learned, it is difficult for the user to adjust the tilt of the target cell. For example, if a user wants to adjust the tilt of cell A, but cannot determine the RET device corresponding to cell A or the anchor RRU corresponding to cell A, the user cannot adjust the tilt of cell A.

[0113] In possible implementations, carriers manage RET devices for multiband antennas primarily through manual means. For example, during engineering and construction, a mapping table between RET devices, cells, and anchor RRUs is maintained offline. When the tilt of a target cell needs to be adjusted, the corresponding RET device and anchor RRU can be determined by querying the mapping table to adjust the tilt of the target cell. However, the aforementioned method of managing RET devices for multiband antennas has limited applicability and can lead to adjustment errors. For example, a user may not find the RET device corresponding to a target cell and therefore cannot adjust the tilt of the target cell, or a user may find the wrong RET device and therefore the tilt of the target cell is incorrectly adjusted. As a result, network performance may be affected.

[0114] In view of the aforementioned technical problems, this application provides a method and communication device for managing a remote electric tilt device, thereby improving the accuracy of performing electric tilt on a cell tilt.

[0115] The following describes a method for managing a remote electric tilt device and a communication device according to embodiments of this application, with reference to the attached drawings.

[0116] Figure 2 is a diagram of a communication system 200 to which embodiments of this application are applicable. As shown in Figure 2, the communication system 200 includes a network device 210, a network device 220, and a terminal device 230. The number of terminal devices and network devices included in the communication system 200 is not limited in this application. Figure 2 is merely an example for illustrative purposes and should not be used to limit the scope of protection of this application. Terminal device 230 may be any of the terminal devices listed above, and network devices 210 and 220 may also be any of the network devices listed above.

[0117] Specifically, network device 210 is a management device for network device 220. For example, if network device 220 is a base station, then network device 210 may be an operation and maintenance center (OMC) and is configured to be responsible for managing the base station. Alternatively, network device 210 may be a general network management device (or system), or a network management device (or system) provided by a carrier or a third party. This is not limited to the present application.

[0118] Specifically, the network device 220 has at least one remote electric tilt device and can manage at least two cells. The terminal device 230 is located within an anchor cell in at least two cells managed by the network device 220. The anchor cell is the cell corresponding to the anchor RRU.

[0119] Figure 3 is a schematic interaction flowchart of Method 300 for managing a remote electric tilt device according to an embodiment of the present application. The method procedure in Figure 3 may be performed by a first and second communication device, or by a module and / or component (e.g., a chip or integrated circuit) having the corresponding function, which may be installed in or connected to the first and second communication devices. This is not limited to this embodiment of the present application. The first communication device may be a network device, and the second communication device may be a network device. Hereinafter, the first and second communication devices will be used as examples for illustrative purposes. As shown in Figure 3, Method 300 includes the following steps.

[0120] S310: The first communication device acquires (e.g., generates) first information, which is used to determine a first mapping table, where each mapping relationship in the first mapping table indicates a correspondence between one remote electric tilt device and one or more cells.

[0121] Specifically, each mapping relationship in the first mapping table may represent a correspondence between one remote electric tilt device and one or more cells, or each mapping relationship may represent a correspondence between the identification of one remote electric tilt device and the identification of one or more cells. In possible implementations, the identification of a remote electric tilt device is the serial number of the remote electric tilt device, the identification of a cell is the cell identification, and the serial number of one remote electric tilt device corresponds to the cell identification of one or more cells. Thus, each mapping relationship in the first mapping table may represent a correspondence between the serial number of one remote electric tilt device and the cell identification of one or more cells. In this way, a remote electric tilt device can be associated with a cell. For the sake of clarity, the following primarily uses the correspondence between a remote electric tilt device and a cell as an example for explanation, but does not limit the description to the correspondence between the serial number of a remote electric tilt device and the identification of a cell.

[0122] S320: The first communication device transmits the first information to the second communication device.

[0123] In response, the second communication device receives the first information from the first communication device.

[0124] Specifically, in step S310, the possible format of the first mapping table is a table. Each row or column of the tabular format of the first mapping table represents a mapping relationship, which indicates the correspondence between one remote electric tilt device and one or more cells. For example, a mapping relationship indicates the correspondence between the identification of one remote electric tilt device (e.g., serial number) and the identification of one or more cells (e.g., cell identification). See Table 1 for a description of the tabular format of the first mapping table.

[0125] [Table 1]

[0126] As shown in Table 1, each row in Table 1 represents one mapping relationship, and one mapping relationship is associated with one remote electric tilt device and one cell. For example, RET device #1 corresponds to cell #1, RET device #2 corresponds to cell #2, ..., and RET device #N corresponds to cell #n. One remote electric tilt device may further correspond to multiple cells, and one cell may also correspond to multiple remote electric tilt devices. This is not limited here. For the form in which one remote electric tilt device corresponds to multiple cells, see the description in Table 1. For the form in which one cell corresponds to multiple remote electric tilt devices, see the description in Table 1. Further details are not described again here. For the sake of clarity, the example in which one remote electric tilt device corresponds to one cell is used for the description in this embodiment of the present application. However, the scenario in which one remote electric tilt device corresponds to multiple cells, and the scenario in which one cell corresponds to multiple remote electric tilt devices, are not limited.

[0127] If one remote electric tilt device corresponds to one cell, this application supports controlling the tilt of one cell by using one remote electric tilt device; if one remote electric tilt device corresponds to multiple cells, this application supports controlling the tilt of multiple corresponding cells by using one remote electric tilt device; and if one cell corresponds to multiple remote electric tilt devices, this application supports controlling the tilt of the cell by using multiple corresponding remote electric tilt devices.

[0128] In possible implementations, the first mapping table can be in the form of an index group. Each index within the index group represents one mapping relationship. For example, index {a} represents [cell #1, RET device #1].

[0129] In possible implementations, the possible form of the first mapping table is a mapping set. Each mapping element within the mapping set represents a single mapping relation pair, e.g., {cell #1, RET device #1}, {cell #2, RET device #2}, ..., and {cell #n, RET device #n}.

[0130] In conclusion, the specific configuration of the first mapping table is not limited in this application, as long as the first mapping table can show the correspondence between the remote electric tilt device managed by the first communication device and the cell.

[0131] In step S310, the first information being used to determine the first mapping table may be that the first information includes the first mapping table, or that the first information includes relevant parameters used to generate the first mapping table. For example, the relevant parameters include at least one of the second and third mapping tables. See below for a specific explanation.

[0132] In a possible implementation, the first piece of information includes at least one of the first mapping table, the second mapping table, or the third mapping table.

[0133] Specifically, each mapping relationship in the second mapping table represents the correspondence between one remote electric tilt device and one frequency band. Each mapping relationship in the third mapping table represents the correspondence between one cell and one frequency band. The first mapping table is determined based on the second and third mapping tables.

[0134] Specifically, each mapping relationship in the second mapping table representing a correspondence between one remote electric tilt device and one frequency band may represent a correspondence between the serial number of one remote electric tilt device and one frequency band. Therefore, each mapping relationship in the second mapping table may represent a correspondence between the serial number of one remote electric tilt device and one frequency band. Similarly, each mapping relationship in the third mapping table representing a correspondence between one cell and one frequency band may represent a correspondence between the cell identification of one cell and one frequency band. Therefore, each mapping relationship in the third mapping table may represent a correspondence between the cell identification of one cell and one frequency band. For the sake of clarity, the following examples will primarily use the correspondence between remote electric tilt devices and frequency bands, the correspondence between cells and frequency bands, and the correspondence between dynamic devices and cells. A unified explanation is provided here, and further details will not be discussed below.

[0135] For a description of the second mapping table, please refer to Table 2. For a description of the third mapping table, please refer to Table 3.

[0136] [Table 2]

[0137] As shown in Table 2, each row in Table 2 represents a mapping relationship, and each mapping relationship is associated with one remote electric tilt device and one frequency band. For example, RET device #1 corresponds to frequency band #1, RET device #2 corresponds to frequency band #2, ..., and RET device #N corresponds to frequency band #n. One frequency band may further correspond to multiple remote electric tilt devices, but this is not limited to the examples given here.

[0138] [Table 3]

[0139] As shown in Table 3, each row in Table 3 represents a mapping relationship, and a mapping relationship is associated with one cell and one frequency band. For example, cell #1 corresponds to frequency band #1, cell #2 corresponds to frequency band #2, ..., and cell #N corresponds to frequency band #n.

[0140] Please note that for the specific configurations of the second and third mapping tables, please refer to the explanation of the specific configuration of the first mapping table. Further details will not be explained again here.

[0141] S330: The second communication device determines the first mapping table based on the first information.

[0142] Specifically, when the first information includes a first mapping table, the second communication device determines the correspondence between the remote electric tilt device managed by the first communication device and the cell based on the first mapping table included in the first information. When the first information includes at least one of the second mapping table and the third mapping table, the second communication device determines the first mapping table based on at least one of the second mapping table and the third mapping table and another pre-configured item in order to determine the correspondence between the remote electric tilt device managed by the first communication device and the cell.

[0143] In Example #1, when the first information includes the second mapping table, the third mapping table is pre-configured in the second communication device. Accordingly, the second communication device generates the first mapping table based on the second mapping table included in the first information and the pre-configured third mapping table. In Example #2, when the first information includes the third mapping table, the second mapping table is pre-configured in the second communication device. Accordingly, the second communication device generates the first mapping table based on the third mapping table included in the first information and the pre-configured second mapping table. In Example #3, when the first information includes the second and third mapping tables, the second communication device generates the first mapping table based on the second and third mapping tables included in the first information.

[0144] It can be understood that each mapping relationship in the second mapping table represents a correspondence between a remote electric tilt device and a frequency band, and each mapping relationship in the third mapping table represents a correspondence between a cell and a frequency band. The second communication device associates the correspondence between the remote electric tilt device and the cell by using an intermediate parameter, namely the frequency band, to generate the first mapping table. For example, if the second mapping table shows that RET device #1 corresponds to frequency band #1, and the third mapping table shows that cell #1 corresponds to frequency band #1, then it can be determined that RET device #1 corresponds to cell #1.

[0145] The first communication device generates first information used to determine the first mapping table. In this application, the correspondence between remote electric tilt devices and cells managed by the first communication device can be automatically obtained, thereby eliminating manual user operation and improving the user experience. Furthermore, when the number of remote electric tilt devices and cells managed by the first communication device changes, the aforementioned solution also helps to obtain updated correspondences between the remote electric tilt devices and cells.

[0146] According to the aforementioned solution, in this application, centralized remote electric tilt management is supported in a "see-it-as-you-go" manner. For example, when electric tilt is performed on the tilt of a cell, the association relationship between the remote electric tilt device and the cell may be directly displayed. For example, when an administrator wants to adjust the tilt of a cell, the administrator can set a cell tilt adjustment command. A first or second communication device can find the remote electric tilt device corresponding to a cell by using a first mapping table, and as a result, the tilt of the corresponding cell can be adjusted by using the remote electric tilt device.

[0147] Furthermore, in this application, by using the aforementioned solution, the accuracy of performing electric tilt on the cell tilt can be improved, and adjustment errors can be avoided.

[0148] In possible implementations, method 300 may further include the following steps:

[0149] S340: The second communication device transmits indication information 1 to the first communication device, indicating that the tilt of the first cell should be adjusted.

[0150] Accordingly, the first communication device receives indication information 1 from the second communication device and adjusts the tilt of the first cell based on the indication information 1.

[0151] S350: The first communication device determines the first remote electric tilt device corresponding to the first cell based on the first mapping table.

[0152] S360: The first communication device adjusts the tilt of the first cell by using the first remote electric tilt device.

[0153] Specifically, the second communication device can determine a first mapping table based on the first information. When the second communication device wants to adjust the tilt of the first cell, it uses the first mapping table to obtain the first remote electric tilt device corresponding to the first cell, and then transmits indication information 1 to the first communication device for adjusting the tilt of the first cell. Indication information 1 may include relevant information about the first remote electric tilt device, such as the serial number of the first remote electric tilt device. Accordingly, the first communication device uses the first remote electric tilt device to adjust the tilt of the first cell based on the indication information 1.

[0154] In a possible implementation, indication information 1 includes the tilt adjustment amount of the first cell and the cell identification of the first cell. Based on the first mapping table and the cell identification of the first cell, the first communication device determines the first remote electric tilt device corresponding to the first cell and adjusts the tilt of the first cell based on the tilt adjustment amount indicated by the second communication device by using the first remote electric tilt device.

[0155] In this way, the present application can support flexible adjustment of the cell tilt managed by the first communication device and ensure the accuracy and convenience of adjusting the cell tilt.

[0156] In possible implementations, method 300 may further include the following steps:

[0157] S310a: The second communication device transmits request information 1 to the first communication device, and request information 1 is used to request the first communication device to transmit the first information to the second communication device.

[0158] Accordingly, the first communication device receives request information 1 from the second communication device and decides to transmit the first information to the second communication device based on the request information 1.

[0159] Optionally, the first communication device may periodically transmit the first information to the second communication device. In this way, the second communication device can at any time obtain the latest correspondence between the remote electric tilt device and the cell managed by the first communication device.

[0160] Step S 310a This is before step S310 Executed Please understand this. In other words, the first communication device transmits the first information to the second communication device in response to request information 1.

[0161] It should be noted that the number of at least one remote electric tilt device and at least two cells managed by the first communication device may or may not have been learned. When the first communication device does not determine the number of remote electric tilt devices and cells managed by the first communication device, the first communication device queries each remote electric tilt device and cell and the remote electric tilt associated with the first communication device. device and may determine the cell. Accordingly, the first communication device determines the correspondence between the remote electric tilt device managed by the first communication device and the cell by using method 300. Furthermore, the first communication device may transmit the correspondence between the remote electric tilt device and the cell associated with the first communication device to the second communication device.

[0162] In possible implementations, the format shown in Table 4 may be used as an alternative for the first mapping table.

[0163] [Table 4]

[0164] As shown in Table 4, the relationships between user BBUs, user cells, anchor BBUs, anchor RRUs, and remote electric tilt devices may be presented in Table 4. In this way, remote electric tilt devices can be easily managed. Information such as user BBUs and user cells in Table 4 may be determined by a first communication device, which may transmit the information to a second communication device, or the aforementioned information may be pre-configured in the second communication device, which may generate a first mapping table in the format of Table 4 based on the pre-configured information and the first information transmitted by the first communication device. This is not limited to the present application. For example, the second communication device scans the BBUs managed by the second communication device and obtains relevant information for each BBU, such as anchor RRUs connected to the BBU, remote electric tilt devices connected to the anchor RRUs, and cell identification associated with the RET devices. In this way, a routing table from cells to remote electric tilt devices shown in Table 4 is constructed.

[0165] Method 300 will be further described below with reference to other attached drawings.

[0166] Figure 4 is a schematic interaction flowchart of Method 400 for managing a remote electric tilt device according to an embodiment of the present application. The method procedure in Figure 4 may be performed by a first communication device, a third communication device, and an antenna device, or by modules and / or components (e.g., chips or integrated circuits) having the corresponding functions that can be installed in or connected to the first communication device, the third communication device, and the antenna device. This is not limited to the present application. Hereinafter, a first communication device, a third communication device, and an antenna device will be used as examples for illustrative purposes. As shown in Figure 4, Method 400 includes the following steps.

[0167] S410: The first communication device transmits indication information 2 to the third communication device, and the indication information 2 instructs the third communication device to transmit the second information to the first communication device.

[0168] Accordingly, the third communication device receives indication information 2 from the first communication device and transmits second information to the first communication device based on the indication information 2.

[0169] Specifically, the first communication device determines, based on the second information, the correspondence between the frequency band and serial number of at least one remote electric tilt device, in whole or in part. See Table 5 for a description of the second information.

[0170] [Table 5]

[0171] As shown in Table 5, each row in Table 5 represents the correspondence between the serial number of one remote electric tilt device and one frequency band (or, each row represents the correspondence between one remote electric tilt device and one frequency band, and is not limited thereto). For example, a remote electric tilt device with serial number 000002110130860B2 corresponds to frequency bands 1710 to 1830, a remote electric tilt device with serial number 000002110130860B1 corresponds to frequency bands 1885 to 2025, and a remote electric tilt device with serial number 000002110130860B3 corresponds to frequency bands 1710 to 1830. One remote electric tilt device corresponds to one frequency band, but one frequency band may correspond to multiple remote electric tilt devices.

[0172] In possible implementations, the second information may indicate some or all of the frequency bands and serial numbers of the remote electric tilt device, or the second information may indicate some or all of the serial numbers of the remote electric tilt device. The aforementioned information may be used by the first communication device to determine the second mapping table. In other words, the information can be used by the first communication device to determine the correspondence between the remote electric tilt device and the frequency band.

[0173] S420: The third communication device transmits query information 1 to the antenna device, and query information 1 instructs the antenna device to transmit the second information to the third communication device.

[0174] Accordingly, the antenna device receives query information 1 from the third communication device and, based on query information 1, determines that the second information needs to be transmitted to the third communication device.

[0175] Specifically, there is an exchange of information between the third communication device and the antenna device. Therefore, the third communication device may transmit query information 1 to the antenna device in order to obtain the correspondence between the frequency band and serial number of some or all of the remote electric tilt devices of the antenna device. The antenna device transmits the respective corresponding query signaling to some or all of the remote electric tilt devices within the antenna device. Upon receiving the query signaling from the antenna device, the remote electric tilt device may feed back to the antenna device the correspondence between the frequency band and serial number corresponding to the remote electric tilt device.

[0176] In the example, a remote electric tilt device within (or connected to) the antenna device feeds back the frequency band and serial number corresponding to the remote electric tilt device to the antenna device. In the example, a remote electric tilt device within the antenna device feeds back the serial number corresponding to the remote electric tilt device to the antenna device. Furthermore, the antenna device collects information about the frequency band and serial number or serial number of at least one remote electric tilt device, in whole or in part, and feeds back that information to a third communication device.

[0177] It can be understood that the antenna device feeds back the serial number of the remote electric tilt device to a third communication device, and the third communication device can establish a correspondence between the serial number of the remote electric tilt device and the frequency band (or between the remote electric tilt device and the frequency band) based on a pre-configured correspondence between the coloring number and the frequency band. Furthermore, the third communication device determines a second mapping table. Furthermore, the third communication device transmits the correspondence between the serial number of the remote electric tilt device and the frequency band to the first communication device.

[0178] S430: The antenna device transmits response information 1 to a third communication device, the response information 1 including a correspondence between the frequency band and serial number of at least one remote electric tilt device, in whole or in part.

[0179] Accordingly, the third communication device receives response information 1 from the antenna device.

[0180] Please understand that the aforementioned Response Information 1 is a response to Query Information 1. Response Information 1 can also be considered as second information.

[0181] S440: The third communication device transmits the second information to the first communication device.

[0182] Accordingly, the first communication device receives the second information from the third communication device.

[0183] S450: The first communication device determines the second mapping table based on the second information.

[0184] Specifically, if the second information includes the serial number and frequency band of the remote electric tilt device, the first communication device may determine the second mapping table based on the serial number and frequency band of the remote electric tilt device, and if the second information includes the serial number of the remote electric tilt device, the first communication device may determine the pre-configured correspondence between the coloring number and the frequency band, and the remote electric tilt device A second mapping table may be determined based on the serial number. Each serial number of a remote electric tilt device corresponds to a single coloring number. Furthermore, please refer to Table 6 for the correspondence between coloring numbers and frequency bands.

[0185] [Table 6]

[0186] As shown in Table 6, one coloring number corresponds to one frequency band. For example, coloring number #R1 corresponds to frequency bands #703 to 803, coloring number #R2 corresponds to frequency bands #703 to 803, coloring number #R3 corresponds to frequency bands #885 to 960, coloring number #R4 corresponds to frequency bands #885 to 960, coloring number #B1 corresponds to frequency bands #1710 to 1830, coloring number #B2 corresponds to frequency bands #1710 to 1830, and coloring number #B3 corresponds to frequency bands #1885 to 2025. One coloring number corresponds to one frequency band range, and one frequency band range may correspond to multiple coloring numbers.

[0187] Since there is a correspondence between the serial number and coloring number of the remote electric tilt device, and a correspondence between the coloring number and frequency band, the second communication device can determine a second mapping table based on the serial number of the remote electric tilt device and the correspondence between the coloring number and frequency band. According to the aforementioned technical solution, the signaling overhead of the third communication device can be reduced, and the third communication device feeds back only the serial number of the remote electric tilt device to the first communication device.

[0188] In a possible implementation, the first communication device is a BBU, the third communication device is an RRU, and the antenna device is an antenna. Accordingly, method 400 may include the following steps:

[0189] S1: The BBU sends frequency band query request information to all RRUs managed by the BBU (which may include anchor RRUs or non-anchor RRUs), and the frequency band query request information is used to request the RRUs to provide feedback on the correspondence between the remote electric tilt device and the frequency band.

[0190] In step S1, the BBU can determine the anchor RRU among the RRUs connected to the BBU. In other words, the BBU can determine the RRU that has an AISG connection line. However, neither the BBU nor the anchor RRU knows the number and serial number of RET devices connected to the anchor RRU. Therefore, the BBU sends frequency band query request information to the anchor RRU to trigger the anchor RRU to query the connected RET devices via the AISG connection line.

[0191] S2: After the anchor RRU receives frequency band query request information from the BBU, it transmits the frequency band query request information to each RET via the AISG connection line.

[0192] After the S3:RET device receives frequency band query request information from the anchor RRU, it returns frequency band query response information to the anchor RRU.

[0193] Accordingly, after receiving frequency band query response information from the RET device, the anchor RRU determines that the anchor RRU is connected to the RET device. The frequency band query response information carries the frequency band and serial number of the RET device.

[0194] S4: The anchor RRU feeds back the frequency bandwidth and serial number of the RET device to the BBU.

[0195] Optionally, the anchor RRU may feed back the frequency bandwidth and serial number of each RET device to the BBU one by one, or it may feed back the frequency bandwidth and serial number of each RET device in batches. This is not limited to the present application.

[0196] S5: The BBU determines a second mapping table based on the frequency bandwidth and serial number of the RET device transmitted by the anchor RRU.

[0197] In a possible implementation, the first communication device is a BBU, the third communication device is an RRU, and the antenna device is an antenna. Accordingly, method 400 may further include the following steps.

[0198] Q1: Enter the correspondence between the color number and the frequency band into the BBU.

[0199] Specifically, in this application, according to the antenna specifications, antenna radio frequency ports for different frequency bands are identified by using different color coding. Each color is then defined by a color coding number, which is included in the serial number of the remote electric tilt device.

[0200] Q2: The BBU stores the correspondence between coloring numbers and frequency bands.

[0201] Q3: The BBU sends serial number query request information to all RRUs managed by the BBU.

[0202] In step Q3, the BBU knows which of the RRUs connected to the BBU is the anchor RRU. In other words, the BBU knows which RRU has the AISG connection line. However, neither the BBU nor the anchor RRU knows which RET device is connected to the anchor RRU. Therefore, the BBU sends serial number query request information to the anchor RRU to trigger the anchor RRU to query the RET device connected to the RRU via the AISG connection line.

[0203] Q4: After the anchor RRU receives the serial number query request information, it sends the serial number query request information to each RET device via the AISG connection line.

[0204] Q5: The RET device reports the serial number corresponding to the RET to the anchor RRU.

[0205] Q6: The anchor RRU returns the serial numbers of all RET devices to the BBU.

[0206] Optionally, the anchor RRU may feed back the serial numbers of the RET devices to the BBU one by one, or it may feed back the serial numbers of the RET devices in batches. This is not limited to the present application.

[0207] Q7: The BBU analyzes the coloring number from the serial number of the RET device, and then establishes the correspondence between the RET and the frequency band by using the stored correspondence between the coloring number and the frequency band.

[0208] According to the aforementioned technical solution, in this application, the first communication device can determine the second mapping table through interaction between the first communication device, the third communication device, and the antenna device.

[0209] Specifically, in this application, information exchange between a first communication device and a third communication device is supported to obtain second information used to determine a second mapping table, and the determined second mapping table is transmitted to the second communication device. Accordingly, the second communication device establishes an association relationship between the remote electric tilt device and the cell managed by the first communication device, based on the pre-configured third mapping table and the second mapping table transmitted by the first communication device, thereby performing accurate electric tilt of the cell tilt and avoiding adjustment errors of the cell tilt. Furthermore, when the number of remote electric tilt devices and cells managed by the first communication device changes, the above solution also helps to obtain an updated correspondence relationship between the remote electric tilt device and the cell.

[0210] Figure 5 is a schematic interaction flowchart of Method 500 for managing a remote electric tilt device according to an embodiment of the present application. The method procedure in Figure 5 may be performed by a first communication device and terminal device, or by modules and / or components (e.g., chips or integrated circuits) having corresponding functions that can be installed in or connected to the first communication device, and modules and / or components (e.g., chips or integrated circuits) having corresponding functions that can be installed in or connected to the terminal device. This is not limited to the present application. Hereinafter, a first communication device and terminal device will be used as an example for illustrative purposes. As shown in Figure 5, Method 500 includes the following steps.

[0211] Optionally, S510: The first communication device transmits request information 2 to the terminal device, requesting the terminal device to report the frequency band and cell identification of each cell.

[0212] Accordingly, the terminal device receives request information 2 from the first communication device and, based on the request information 2, reports the frequency band and cell identification of each cell to the first communication device.

[0213] Specifically, the terminal device in step S510 is located within an anchor cell of at least two cells managed by the first communication device. The terminal device may perform common coverage measurements for each cell. For example, the first communication device may configure the terminal device in the anchor cell to perform inter-frequency / inter-RAT cell detection.

[0214] Specifically, the terminal device performs inter-frequency / inter-RAT cell detection within the anchor cell and then transmits the acquired measurement results to the first communication device. The measurement results include the cell identification and frequency bandwidth of each cell.

[0215] S520: The terminal device transmits feedback information 1 to the first communication device, and feedback information 1 includes the cell identification and frequency band of each cell.

[0216] Accordingly, the first communication device receives feedback information 1 from the terminal device.

[0217] In possible implementations, cell identification may include a physical cell identifier (PCI) or another identifier used to distinguish cells. This is not limited to the present application.

[0218] S530: The first communication device determines a third mapping table based on the cell identification and frequency band of each cell.

[0219] In conclusion, the first communication device determines the third mapping table by interacting with the terminal device.

[0220] In this embodiment of the present application, a common coverage learning process is used as an example to illustrate how a terminal device acquires cell identification and frequency bandwidth for each cell; however, it should be noted that other possible implementations are not limited. For a specific description of common coverage learning, please refer to existing protocols. Further details are not described here.

[0221] In a possible implementation, the first communication device is a BBU, and the second communication device is an OMC. Method 500 may further include the following steps:

[0222] W1:OMC sends measurement request information to the BBU corresponding to the anchor RRU.

[0223] Specifically, the measurement request information is used to trigger the BBU, instructing terminal devices within the anchor cell to perform a common coverage measurement.

[0224] W2:BBU configures the terminal device to perform inter-frequency / inter-RAT cell detection within the anchor cell after receiving measurement request information from OMC.

[0225] W3: The terminal device performs inter-frequency / inter-RAT cell detection within the anchor cell and then transmits the measurement results, including the cell identification and frequency bandwidth of each cell, to the BBU.

[0226] Furthermore, the BBU determines a third mapping table based on the measurement results transmitted by the terminal device.

[0227] Optionally, the BBU may also send measurement results transmitted by terminal devices to the OMC, which performs common sector identification and obtains a third mapping table.

[0228] According to the aforementioned technical solution, in this application, the first communication device can determine a third mapping table through interaction between the first communication device and a terminal device.

[0229] Specifically, in this application, information exchange between a first communication device and a terminal device is supported to determine a third mapping table and to obtain information regarding the frequency band and cell identification of each cell, and the determined third mapping table is transmitted to a second communication device. Accordingly, the second communication device establishes an association relationship between the remote electric tilt device managed by the first communication device and the cell, based on the pre-configured second mapping table and the third mapping table transmitted by the first communication device, in order to perform accurate electric tilt of the cell tilt and avoid adjustment errors of the cell tilt. Furthermore, when the number of remote electric tilt devices and cells managed by the first communication device changes, the above solution also helps to obtain an updated correspondence relationship between the remote electric tilt device and the cell.

[0230] It should be noted that methods 400 and 500 can be combined with each other to form a new technical solution. For example, the first communication device may determine a second mapping table by using method 400 and a third mapping table by using method 500, or the first communication device may determine a third mapping table by using method 500 and a second mapping table by using method 400. Accordingly, the first communication device may transmit at least one of the second and third mapping tables to the second communication device, or the first communication device may transmit a first mapping table generated by the first communication device to the second communication device based on the second and third mapping tables. This is not limited to the present application.

[0231] It should be further noted that the second communication device may have a common sector identification function, a routing table function, and a route scheduling function. Specifically, the common sector identification function refers to determining which cells are common sector cells based on the common coverage learning results fed back by the first communication device. The routing table function refers to establishing correspondences between cells and RET devices based on the common sector identification results. The route scheduling function refers to using a routing table to support the automatic management of RET devices. For example, when a cell is input, corresponding RET information may be returned, the cell's tilt may be adjusted, and the corresponding RET device may be automatically found by the system. The first communication device has an RET device information management function and a common coverage learning function. The RET device information management function refers to being able to obtain information about all RET devices, including the frequency band and serial number of the RET devices. The common coverage learning function refers to performing common coverage processing on anchor cells corresponding to anchor RRUs and being responsible for identifying adjacent cells between common coverage frequencies based on common coverage learning. The antenna device has an information base for RET devices. The antenna device can provide a query interface for a third communication device to query information about RET devices.

[0232] The following section further describes the aforementioned method for managing the remote electric tilt device, with reference to Figure 6.

[0233] Figure 6 is an application diagram of a method for managing a remote electric tilt device according to an embodiment of the present application. As shown in Figure 6, the dashed lines between the BBU, RRU, cell, and RET device indicate the logical relationship between the four, but not the physical connection relationship between them. RRU3 is an anchor RRU and may be connected to RET device 1 through RET device 3 via an AISG interface (see solid line in Figure 6) to adjust the tilt of the corresponding cell. The correspondence between the RET devices and the cell can be obtained by using the method described above. BBU1 through BBU3 in Figure 6 are connected to a second communication device (e.g., a network management system), and an administrator may input parameters or control commands to the second communication device. For example, the administrator may input a cell tilt adjustment command to the second communication device via an interface operating system, and the second communication device may control RRU3 by using BBU3, thereby, RET RET device 3 can be controlled from device 1 by using RRU3. In this way, the tilt of the corresponding cell is precisely adjusted. For example, if an administrator (or a second communication device) adjusts the tilt of cell 3 by setting, the second communication device can control RET device 3 by using RRU3 to perform the precise adjustment of the tilt of cell 3. In another example, if an administrator (or a second communication device) adjusts the tilt of cell 1 by setting, the second communication device can control RET device 1 by using RRU3 to perform the precise adjustment of the tilt of cell 1.

Whether the functions in the aforementioned functions are performed in the form of a hardware structure, a software module, or a combination of a hardware structure and a software module depends on the specific application and design constraints of the technical solution.
