Description

Technical Field

[0001] This application relates to the field of communications, and in particular, to a device configuration method, a communication device, and a system. Background Art

[0002] Generally, the new installation / switching of a base station usually includes two stages: the base station installation stage and the commissioning stage. For the base station installation stage, the site maintenance personnel can complete the base station installation by performing hardware connections according to the base station installation drawing instructions. For the commissioning stage, the site maintenance personnel transfer the site name and the electronic serial number (ESN) to the back-end network management personnel. The network management personnel complete the site opening data configuration based on the site name and the ESN, and then notify the site maintenance personnel that the site opening data configuration is completed. The site maintenance personnel power on the base station proximally. After the base station is powered on, it obtains the opening data corresponding to the ESN from the network element management system according to the ESN, so as to enable the base station.

[0003] The above method requires manual or third-party participation to activate a new base station or replace a base station. The operation steps for enabling the base station are relatively complex, and the station opening efficiency is low. Therefore, how to improve the device configuration efficiency has become an urgent problem to be solved. Summary of the Invention

[0004] This application provides a device configuration method, a communication device, and a system, which are used to improve the efficiency in the case of opening a station or replacing a device in a device replacement scenario.

[0005] In view of this, in a first aspect, this application provides a device configuration method, which can be applied to a communication system, which can also be referred to as a communication network. The communication system can include a network management device and one or more devices connected to the network management device, including: the first device is any one of the foregoing one or more devices. If the first device is replaced by a second device, the first device is connected to one or more connection devices before replacement. After the first device is replaced by the second device, the one or more connection devices are connected to the second device; after the second device is powered on, the second device sends a first message, which can include information saved by at least one connection device; the second device receives configuration information, which is used to configure the second device, and the configuration information can include one or more parameters used when the second device operates in the communication system, so as to support the normal operation of the second device in the communication system.

[0006] The method provided by the embodiments of the present application can be applied to the device replacement scenario in a communication system. Usually, the network management side stores the configuration information corresponding to the old device and the information of the connection devices connected to the old device. Or rather, the network management side can store the configuration information of each device in the communication system and the information of the topology structure. In the embodiments of the present application, when a device is replaced, the new device can obtain the configuration information available for the new device from the network management side based on the information stored by the connection devices. The network management side can use the stored configuration information of each device in the communication system and the information of the topology structure to obtain the configuration information of the new device and send it to the new device, so as to achieve more intelligent device configuration in the device replacement scenario. During the device configuration process, no manual or third-party participation is required, that is, the manual participation process or the third-party participation process is reduced, and the device configuration efficiency can be improved.

[0007] In a possible implementation manner, the foregoing method may further include: the second device updates the configuration of the second device according to the configuration information. After the second device receives the configuration information, it can configure based on this configuration information. For example, the first configuration parameter may carry parameters such as the frequency point, power, bandwidth or azimuth angle of the sector of the second device. The second device can configure the frequency point, power, bandwidth or azimuth angle of the sector of the second device based on the configuration information, so that the second device can operate normally in the communication system based on the configured parameters.

[0008] In a possible implementation manner, the foregoing at least one connection device includes one or more of the following: an optical module, an antenna device, a global positioning system ground receiver or a power supply. The optical module can be used to convert optical signals and electrical signals to transmit electrical signals as optical signals. The antenna device is used to provide hardware support for the wireless transmission of data and can convert electrical signals into electromagnetic wave signals to wirelessly transmit data. The global positioning system ground receiver is used to obtain positioning information. Therefore, in the embodiments of the present application, the connection device can specifically be an optical module, an antenna device, a global positioning system ground receiver or a power supply, etc., which can realize the reuse of available devices and improve the device utilization rate.

[0009] In a possible implementation manner, the information stored by the foregoing at least one connection device includes at least one of the following: the serial number of the optical module, the serial number of the antenna device, the serial number of the remote global positioning system or the serial number of the power supply. Therefore, in the embodiments of the present application, the information stored by the connection device can include the identification information of each connection device, so that the second device can obtain more accurate identification of each connection device, and then obtain the configuration based on more accurate information, improving the success rate of obtaining the correct configuration.

[0010] In a possible implementation manner, the foregoing configuration information includes one or more of the following configuration information of the second device: mode information, sector information, address information, and information of the virtual local area network to which the second device belongs. The mode information may include information about the modes supported by the second device, the sector information may include information about the sectors corresponding to the second device, the address information may include the address of the second device when it operates in the communication system, and the information of the virtual local area network to which the second device belongs may include information of the second device in the virtual local area network to which it belongs, for indicating that the second device operates normally in the virtual local area network to which it belongs.

[0011] In a possible implementation manner, the foregoing method may further include: the second device obtains first information. After the second device is powered on, it may obtain the information saved by at least one connection device for establishing a connection, so as to subsequently request configuration information from the network management device.

[0012] In a possible implementation manner, the second device obtaining the first information may include: the second device reads the first information from at least one connection device. Before the first device is replaced with the second device, the first information corresponds to the first device, and the first information includes the information written by the first device into the storage space of at least one connection device. Therefore, in the implementation manner of the present application, the first device can directly write information into the connection device (i.e., the reused connection device), so that the second device can obtain more accurate information based on the information saved by the connection device to obtain the required configuration information of the second device, improving the configuration success rate and the configuration efficiency.

[0013] In a possible implementation manner, the foregoing first information may further include information of the first device, such as the ESN of the first device, the name, or the configuration information of the first device, etc. For example, after the first device completes configuration, if the storage space of the connection device is not less than the size occupied by the configuration information of the first device, the first device may write the configuration information of the first device into the storage space of the connection device; if the storage space of the connection device is less than the size occupied by the configuration information of the first device, the first device may write identification information such as the ESN or name of the first device into the storage space of the connection device, thereby implementing data backup of the first device.

[0014] In a possible implementation manner, after the second device receives the configuration information of the second device, the foregoing method may further include: the second device writes second information into at least one connection device, and the second information may include information of the second device, such as an identifier of the second device, a device type, or all or part of the configuration information of the second device, etc. The second information is used for the third device to obtain corresponding configuration from the network management device after the second device is replaced by the third device. Therefore, in the implementation manner of the present application, after the second device is configured, data can also be backed up in the connection device, so that after the device is replaced next time, a more accurate configuration can be obtained again based on the information saved in the connection device.

[0015] In a possible implementation manner, the foregoing method may further include: the second device sends information of the second device, such as the name of the second device, ESN, or device type, etc. Therefore, when the second device requests the configuration information of the second device from the network management device, it can also send its own information, so that when the network management device generates the configuration information of the second device, it can combine the information of the second device to generate configuration information adapted to the second device. And when the network management device updates the configuration information of the device it saves, it can associate the information of the second device with the configuration information of the second device, which is equivalent to saving the mapping relationship between the second device and the configuration information of the second device.

[0016] In a second aspect, the present application provides a device configuration method, which can be applied to a communication system. The communication system may include a network management device and one or more devices connected to the network management device. The method includes: the first device is any one of the foregoing one or more devices. If the first device is replaced by the second device, the network management device receives first information, and the first information includes information saved by at least one connection device, and the at least one connection device is a device connected to the second device; the network management device sends the configuration information of the second device according to the first information, and the configuration information of the second device is used to configure the second device.

[0017] In the implementation manner of the present application, after the first device is replaced by the second device, the second device can use the information saved by the connection device to request the configuration information of the second device from the network management device. Therefore, during the configuration process of the new device after the device is replaced, the configuration of the new device can be achieved without manual or third-party participation, improving the configuration efficiency of the new device.

[0018] In a possible implementation manner, the foregoing network management device may include, according to the configuration information of the first information sent to the second device: the network management device obtains the configuration information of the first device from the associated data according to the first information, and the associated data includes the configuration information of multiple devices, and the multiple devices include the first device; the network management device sends the configuration information of the second device according to the configuration information of the first device, for example, the configuration information of the first device may be used as the configuration information of the second device, or the configuration information of the second device may be generated based on the configuration information of the first device, etc.

[0019] In an embodiment of the present application, the network management device may extract the configuration information of the first device from the obtained associated data, and obtain the configuration information of the second device based on the configuration information of the first device.

[0020] In a possible implementation manner, the foregoing network management device may include, according to the configuration information of the first device sending the configuration information of the second device: the network management device uses the configuration information of the first device as the configuration information of the second device and sends the configuration information of the second device.

[0021] In an embodiment of the present application, the network management device may directly use the old device configuration as the new device configuration. For example, in the scenario where the replaced new device has the same model as the old device, the configuration of the new device can be quickly realized.

[0022] In a possible implementation manner, the foregoing method may further include receiving the information of the second device. The foregoing network management device may include, according to the configuration information of the first device sending the configuration information of the second device: the network management device generates the configuration information of the second device for the second device according to the configuration information of the first device and the information of the second device, and sends the configuration information of the second device.

[0023] In an embodiment of the present application, the network management device generates the adapted configuration information of the second device for the new device based on the configuration of the old device and the information of the new device, thereby improving the configuration efficiency and configuration success rate of the new device.

[0024] In a third aspect, the present application provides a device configuration method, including:

[0025] The connection device receives the backup data sent by the first device and saves the backup data to the local storage space; after the first device is replaced by the second device, if a read message of the second device is received, and the read message is used to indicate reading the backup data saved in the storage space, the connection device sends the backup data sent by the first device to the second device.

[0026] Therefore, in the embodiments of the present application, data backup can be performed in the storage space of the connection device. When a device in the communication system is replaced, the new device can read the data from the storage space, and this data can be used for the new device to request configuration information from the network management device. Thus, during the configuration process of the new device, the configuration of the new device can be achieved without manual or third-party participation.

[0027] In a possible implementation manner, the data stored in the foregoing storage space may specifically be the configuration information of the first device. Therefore, the second device can directly read the configuration information of the first device from the connection device, and thus obtain the configuration information of its own second device based on the configuration information of the first device.

[0028] In a possible implementation manner, the data stored in the foregoing storage space may specifically be the identification information or device type, etc. of the first device. Thus, the new device can read the identification or device type of the old device, and request the configuration information of the second device from the network management device based on the information of the old device.

[0029] In a possible implementation manner, after the second device completes the configuration, data backup can also be performed in the storage space of the connection device. For example, write the identification information, device type or configuration information of the second device, etc. into the storage space. So that when the device is replaced next time, the configuration of the replaced device can be obtained based on the backup data.

[0095] Figure 1 To illustrate a possible and non-limiting schematic diagram of a communication system (or referred to as a communication network). As Figure 1 shown, the communication system includes a Radio Access Network (RAN) and a Core Network (CN). The RAN includes at least one RAN node and at least one user equipment. Other RAN nodes may also be included in the RAN, for example, wireless relay devices and / or wireless backhaul devices ( Figure 1 not shown in the figure) and so on. The user equipment is connected to the RAN node wirelessly. The RAN node is connected to the core network wirelessly or by wire. The core network devices in the core network and the RAN nodes in the RAN can be different physical devices respectively, or can be the same physical device integrating the core network logic function and the radio access network logic function.

[0096] The RAN can be a cellular system related to the 3rd Generation Partnership Project (3GPP), such as a 4G or 5G mobile communication system, or a future evolved system (such as a 6G mobile communication system). The RAN can also be an Open RAN (O-RAN or ORAN), a Non-Terrestrial Network (NTN) system, or a Wireless Fidelity (WiFi) system. The RAN100 can also be a communication system that integrates two or more of the above systems.

[0097] RAN nodes, sometimes also referred to as access network devices, access devices, RAN entities, or access nodes, etc., form part of a communication system and are used to assist terminals in achieving wireless access. Multiple RAN nodes in a communication system can be of the same type or different types. RAN nodes and user equipment are sometimes both referred to as communication devices.

[0098] In one possible scenario, the RAN node can be a base station, a satellite base station, an evolved NodeB (eNodeB), a Transmission Reception Point (TRP), a next generation NodeB (gNB), a next generation base station in a 6th Generation (6G) mobile communication system, a base station in a future mobile communication system, or an access node in a WiFi system, etc. The RAN node can be a macro base station, a micro base station or an indoor station, a relay node or a donor node, or a radio controller in a Cloud Radio Access Network (CRAN) scenario. Optionally, the RAN node can also be a server, a wearable device, a vehicle or in-vehicle equipment, etc. For example, the access network device in Vehicle-to-Everything (V2X) technology can be a Road Side Unit (RSU).

[0099] In another possible scenario, multiple RAN nodes cooperate to assist a user equipment in achieving wireless access, and different RAN nodes respectively implement some functions of a base station. For example, the RAN node may be a central unit (CU), a distributed unit (DU), a CU-control plane (CP), a CU-user plane (UP), or a radio unit (RU), etc. The CU and the DU may be separately provided, or may also be included in the same network element, such as a baseband unit (BBU). The RU may be included in a radio device or a radio unit, such as included in a remote radio unit (RRU), a remote radio head (RRH), a radio frequency unit (RFU), or an active antenna unit (AAU).

[0100] In different systems, the CU (or CU-CP and CU-UP), DU, or RU may also have different names, but those skilled in the art can understand their meanings. For example, in the ORAN system, the CU may also be referred to as an O-CU (open CU), the DU may also be referred to as an O-DU, the CU-CP may also be referred to as an O-CU-CP, the CU-UP may also be referred to as an O-CU-UP, and the RU may also be referred to as an O-RU.

[0101] This application describes by taking the RAN node as an example of an access network device.

[0102] Refer to Figure 2 , exemplarily, a schematic diagram of the architecture of another communication system provided by this application. The communication system may include a RAN node 20 and a network management system 21, and the network management system may include at least one network management device.

[0103] The network management system may be independently deployed or may be deployed in a core network.

[0104] Correspondingly, the network management system may configure all or some of the functions implemented by the RAN node, such as performing resource configuration or resource scheduling for the RAN node, etc.

[0105] In addition, the device connected to the RAN node may further include an optical module, an antenna line device (ALD), a remote global positioning system (RGPS), or a power module, etc. The power module may specifically include a module for power supply such as an uninterruptible power supply (UPS) or a battery, etc. The above device connected to the RAN node may also be referred to as a peripheral device, a connection device, or an interconnection device, etc. The above device and the RAN node may be co-located or separately located, which is not limited in this application.

[0106] For the connection device connected to the RAN node, it can be used to support the operation of the base station. For example, it can provide hardware support for the wireless communication function of the base station, provide energy, provide wireless transmission support, etc. Among them:

[0107] Optical module: It can be used to convert optical signals into electrical signals and can be used for the transmission of information between the DU and the RU in the RAN node.

[0108] ALD: It can be used to convert electrical signals into electromagnetic wave signals for wireless transmission of data. When the RAN node is the RU, the RU can communicate with the ALD according to the protocol specifications of the antenna interface standards group (AISG), or can also communicate according to the protocol agreed between the RU and the ALD, etc.

[0109] RGPS: It can be used in the RAN node to implement the positioning function.

[0110] Power module: It can be used to provide electrical energy for the RAN node and may specifically include a UPS or a battery, etc. The UPS is a power supply containing an energy storage device. When the UPS is connected to the RAN node, it can provide an uninterrupted power supply for the RAN node. The battery is also an energy storage device and can directly provide electrical energy for the RAN node by consuming the energy stored in itself. Through the connection between the RAN node and the connection device, the operation or data processing or transmission function of the access network device is realized.

[0111] Generally, the new installation / change of a base station usually includes two phases: the base station installation phase and the commissioning phase. For the base station installation phase, the site maintenance personnel can complete the base station installation by making hardware connections according to the base station installation drawing instructions. For the commissioning phase, first, the site maintenance personnel transfer the site name and electronic serial number (ESN) to the back-end network management personnel. The network management personnel complete the site opening data configuration based on the site name and ESN, and then notify the site maintenance personnel that the site opening data configuration is completed. The site maintenance personnel power on the base station proximally. After the base station is powered on, it obtains the opening data corresponding to the ESN from the network element management system according to the ESN, so as to commission the base station. Therefore, in the commissioning phase, it is necessary for the front-end site maintenance personnel to communicate with the back-end network management personnel about the ESN of the currently installed base station, so that the base station can obtain the opening data according to the ESN after being powered on to commission the base station. The operation steps for commissioning the base station in the existing solution are relatively complex.

[0112] Secondly, currently, the opening of a base station is based on the network element granularity. The base station opening data includes two parts: DU and RU; the network planning personnel need to plan the DU and RU used for the site according to the site name, and the front-end maintenance personnel also need to accurately install them in the corresponding positions according to the planned device list.

[0113] In addition, in some possible solutions, a method of obtaining opening data based on the location information of the site to be opened is also used to automatically obtain the opening data during the base station opening process to complete the base station opening. Obtaining opening data by reporting the site location information relatively reduces the manual intervention process; however, with the method of configuring opening data based on the site location, the network management system can only know the site location and cannot accurately know which device is being configured, so it cannot confirm the installation status of all modules of the site; at the same time, for the front-end radio frequency devices, it is impossible to determine the correctness of the installation azimuth angle and the configuration accuracy of multiple front-end radio frequency devices at similar locations. That is, third-party access is also required to achieve the opening or replacement of the site.

[0114] Therefore, the present application provides a device configuration method to improve efficiency in the case of opening a station or replacing equipment.

[0115] Refer to Figure 3 , the flowchart of a device configuration method provided by the present application. The method may include the following steps:

[0116] 301. After the first device is replaced with the second device, the second device sends the first information to the network management device.

[0117] The first device or the second device may specifically be a module in the foregoing RAN node. For example, the first device or the second device may be at least one of modules such as AAU, RRU, RRH, RFU, RU, etc. The first device and the second device may be of the same type of module. For example, they may both be AAUs. Of course, they may also be of different types of modules. For example, the first device is an AAU and the second device is an RRU.

[0118] After replacing the first device with the second device, one or more connection devices connected to the first device before replacement can be reused, that is, the one or more connection devices establish connections with the second device. The one or more connection devices may specifically include but are not limited to the foregoing optical modules, ALD, RGPS, or UPS and other modules.

[0119] The first information may include the information saved by the first or more connection devices.

[0120] In a possible implementation manner, the information saved by the one or more connection devices may specifically include the identification information of the connection device. For example, the information saved by the one or more connection devices may include but are not limited to: the serial number (SN) of the optical module, the SN of the ALD, the SN of the RGPS, or the identification of the power module (such as the SN of the UPS), etc. Specifically, when the one or more connection devices include an optical module, the first information may include the SN of the optical module; when the one or more connection devices include an ALD, the first information includes the SN of the ALD; when the one or more connection devices include an RGPS, the first information may include the SN of the RGPS; when the one or more connection devices include a power module, the first information may include the identification of the power supply, such as the SN of the UPS.

[0121] In addition, the information saved by the connection device may further include the information of the first device, that is, the first information may further include the information of the first device. The information of the first device may specifically include the identity information of the first device (such as the ESN22 of the first device or the device name, etc.) or the device type of the first device, etc.

[0122] If a storage space for storing data is provided in the connection device, before the first device is replaced, the first device may write data in the storage space. For example, the first device may write the identification information of the first device (such as the serial number or name, etc. of the information) and the configuration information of the first device. After the first device is replaced with the second device, the second device may actively read the data stored in the storage space, or the connection device may send the data in the storage space to the second device, etc., so that the second device obtains the information saved by the connection device.

[0123] Therefore, after the first device is replaced with the second device, if the first device has written its identification information in the storage space, the second device can read the identification information of the first device to facilitate obtaining the configuration information of the second device subsequently.

[0124] In a possible implementation manner, the second device may also send information of the second device to the network management device, so that the network management device can configure more suitable configuration information based on the information of the second device.

[0125] In some possible scenarios, before the first device is replaced, the first device before replacement may also write its configuration information in the storage space set in the connection device, and the second device can read the configuration information of the first device from this storage space. The description of the configuration information of the first device can refer to the description of the configuration information of the second device in step 302 below, and will not be elaborated here.

[0126] In the scenario where the second device reads the configuration information of the first device from the connection device, the second device can use the configuration information of the first device as its own configuration information, so that the second device can efficiently obtain its own information based on the information saved in the connection device. The second device can also send the information of the first device to the network management device, and the network management device can obtain the configuration information of the second device according to the configuration information of the first device, which can improve the efficiency of the network management device in obtaining the configuration information of the first device.

[0127] 302. The network management device sends the configuration information of the second device to the second device.

[0128] The network management system can save associated data, which can include the configuration information of each device in the communication system and the information of the topological structure of each device.

[0129] The configuration information of each device specifically can include the configuration information of one or more devices in the communication system. The configuration information of each device can be used to support the device to communicate in the communication network. The configuration information of each device specifically can include the configuration parameters of the communication resources of the device to support the device to run in the communication network.

[0130] The information of the topological structure of each device can include the information of the connection relationship between each device in the communication system or between each device and the corresponding connection device. Each device in the communication system can include the first device before replacement. Correspondingly, the information of the topological structure of each device can include the information of the connection relationship between the first device before replacement and one or more connection devices connected to it.

[0131] The network management device can use the first information sent by the second device to obtain the configuration information of the first device from the associated data. For example, the configuration information of the first device can be queried from the associated data based on the identifier of one or more connected devices carried in the first information.

[0132] Obtain the configuration information of the second device based on the configuration information of the first device. For example, the configuration information of the first device can be used as the configuration information of the second device, or the configuration information of the first device can be adjusted and then used as the information of the second device, etc. The specific ways to adjust the configuration information of the first device can include adjusting it to the wireless resource configuration parameters configured for the second device or adjusting the hardware configuration parameters of the second device, etc.

[0133] Subsequently, the network management device sends the configuration information of the second device to the second device. The configuration information of the second device can be used to configure the second device, thereby supporting the second device to operate in the communication network.

[0134] Optionally, the configuration information of the second device in the embodiments of the present application may specifically include, but is not limited to, one or more of the following information: system information, sector information, address information, information of the virtual local area network to which it belongs, etc.

[0135] Among them, the system information may include information about the network systems supported by the second device. For example, the system information may be the LTE system, or the NR system, etc. That is, if the system information is the LTE system, then the second device supports the LTE system.

[0136] The sector information may include information about the sectors under the second device, and may specifically include information such as the frequency points, power, bandwidth, or direction angles of the sectors. For example, the wireless signal coverage range of a base station can usually be divided into multiple sectors, and each device in the base station can cover one or more of these sectors. For example, the sector information configured for the second device can include the information about the sectors supported by the second device. For example, the sector information may be the information of Sector 1, Sector 2, or Sector 3. If the sector information is the information of Sector 1, then the second device corresponds to Sector 1, or it can also be understood that the second device provides communication functions for the users served by Sector 1, and so on.

[0137] The address information may include various types of addresses of the second device. For example, the address information may include at least one of the IP address and the call home address. For example, if the address information includes the IP address, then the IP address of the second device is the IP address in the address information.

[0138] The information of the virtual local area network may include the information of the second device in the virtual local area network, such as the identifier or name of the second device in the virtual local area network, etc. For example, the information of the virtual local area network may include the identifier (ID) of the virtual local area network. For example, the identifier of the virtual local area network may be represented by the virtual local area network (VLAN) ID.

[0139] The method provided by the embodiments of this application can be applied to the device replacement scenario in a communication system. The network management system usually stores the configuration information corresponding to the device before replacement and the information of the connection devices connected to the device before replacement. Or rather, the network management system can store the configuration information of each device in the communication system and the information of the topological structure. In the embodiments of this application, when a device is replaced, the replaced device can obtain the configuration information available for the new device from the network management system based on the information stored by the device before replacement. The network management system can use the stored configuration information of each device in the communication system and the information of the topological structure to obtain the configuration information of the new device and send it to the new device, so as to achieve more intelligent device configuration in the device replacement scenario. During the device configuration process, there is no need for manual or third-party participation, that is, the manual participation process or the third-party participation process is reduced, and the device configuration efficiency can be improved. And compared with the configuration method based on the positioning of the device, the embodiments of this application use the information of the connection device to request the configuration information from the network management device, which can enable the network management device to more accurately distinguish the front-end device and the remote device, and achieve more accurate device configuration.

[0140] Next, step 302 will be introduced in detail.

[0141] First, the network management system can store associated data, which can specifically include the information of each device in the communication network and the corresponding configuration information. For example, it may include the ESN of each device and the corresponding configuration information, that is, associate the ESN of each device with the configuration information, so that the network management system can query the configuration information of the device based on the ESN of the device.

[0142] The associated data may also include the information of the connection devices corresponding to each device. The connection device corresponding to each device is the information of the device connected to each device. For example, the information of the connection device corresponding to each device can be stored in the associated data. For example, it may include the SN of the optical module, the SN of the ALD, the SN of the RGPS or the SN of the UPS connected to each device, etc. Thus, the network management system can query the ESN and configuration information of the corresponding device based on the SN of the connection device.

[0143] Among them, the associated data can be stored in the network management device or in a separately deployed database. When the associated data is stored in a separately deployed database, the network management device can use the read instruction of the database to read the associated data from the database. If the associated data is stored in the network management device, there can be multiple cases. Specifically, the network management system may include one or more network management devices. In the case where the network management system includes only one network management device, the network management device can directly read the associated data locally. In the case where the network management system includes multiple network management devices, after the network management device connected to the second device receives the first information sent by the second device, if the associated data of the configuration information of the first device is stored in other network management devices, the network management device connected to the second device can request the associated data from other network management devices.

[0144] Secondly, the network management device can query the configuration information of the first device from the associated data based on the first information.

[0145] In a possible implementation manner, the first information may carry information of one or more connected devices connected to the first device before replacement. The network management device can query the configuration information of the first device corresponding to the connected device from the associated data based on the information of the connected device carried in the first information. For example, when the serial number (SN) of an optical module is included in the first information, the network management device can query the configuration information of the device corresponding to the SN of the optical module from the associated data to obtain the configuration information of the first device; when the SN of an ALD is included in the first information, the network management device can query the configuration information of the device corresponding to the ALD from the associated data to obtain the configuration information of the first device; when the SN of an RGPS is included in the first information, the network management device can query the configuration information of the device corresponding to the SN of the RGPS from the associated data to obtain the configuration information of the first device; when the SN of an UPS is included in the first information, the network management device can query the configuration information of the device corresponding to the SN of the UPS from the associated data to obtain the configuration information of the first device.

[0146] In a possible implementation manner, the first information may further carry information of the first device, such as the ESN of the first device. The network management device can query the corresponding configuration information from the associated data based on the information of the first device to obtain the configuration information of the first device.

[0147] Subsequently, after the network management device queries and obtains the configuration information of the first device from the associated data, it can obtain the configuration information of the second device based on the configuration information of the first device and send the configuration information of the second device to the second device.

[0148] Specifically, the network management device can directly use the configuration information of the first device as the configuration information of the second device, or can obtain the configuration information of the second device after adjusting the parameters of the configuration information of the first device.

[0149] In a possible implementation manner, the network management device uses the configuration information of the first device as the configuration information of the second device and sends the configuration information of the second device to the second device. That is, the network management device can directly send the configuration information of the old device to the new device, so that the new device can reuse the configuration of the old device. For example, when the models of the first device and the second device are the same, that is, the second device supports the frequency band or power supported by the first device, etc., the configuration information of the first device can be directly used as the configuration information of the second device, that is, the second device can operate normally based on the configuration information of the first device, and the configuration information of the first device can be used as the configuration information of the second device.

[0150] In a possible implementation manner, the second device also sends the information of the second device to the network management device, such as the ESN of the second device. The network management device can generate the configuration information of the second device according to the configuration information of the first device and the information of the second device. For example, the information of the second device may include the ESN, device type, supported parameter range, etc. of the second device. The network management device generates configuration information adapted to the functions supported by the second device based on this information, so that the second device can operate based on more adapted configuration information. For example, the network management device can obtain the range of parameters such as the frequency band, power or azimuth angle supported by the second device based on the information of the second device. If the range of parameters such as the frequency band, power or azimuth angle supported by the second device is different from the range indicated by the configuration information of the first device, more adapted configuration information can be allocated to the second device based on the parameters such as the frequency band, power or azimuth angle supported by the second device, and the configuration information of the second device can be obtained. For example, the sector frequency band included in the generated configuration information of the second device is within the frequency band supported by the second device, and the sector power is within the power range supported by the second device, etc., so as to allocate more adapted configuration information to the second device.

[0151] Optionally, after obtaining the configuration information of the second device, the network management device can also update the associated data. Save the information of the second device and the configuration information of the second device in the associated data, or replace the information of the first device and the configuration information of the first device in the original associated data with the information of the second device and the configuration information of the second device, so that the network management device can query the configuration information of the second device from the associated data later.

[0152] The method flow provided by the present application is introduced above. Next, in combination with the application scenario, the method flow provided by the present application will be introduced in more detail.

[0153] Exemplarily, the first device and the second device are introduced as radio frequency units in the RAN node. The aforementioned first device may be the radio frequency unit 0 mentioned below, and the second device may be the radio frequency unit 1 mentioned below. The RAN node may refer to the corresponding RAN node 20 in the foregoing Figure 2 The description of radio frequency units such as the foregoing BBU, AAU or RRU can be referred to for the radio frequency unit 0 and the radio frequency unit 1.

[0154] Refer to Figure 4 , the flowchart of another device configuration method provided by this application is as follows.

[0155] 401. Save associated data in the communication network.

[0156] After the configuration of each radio frequency unit in the communication network is completed, the network management device can save the association relationship between the information of each radio frequency unit in the communication network and the configuration information in the associated data. For example, after the configuration of the radio frequency unit 0 is completed, the identifier of the radio frequency unit 0 and the corresponding configuration information can be saved in the associated data. The configuration information in this associated data can specifically refer to the relevant description of the configuration information in the foregoing step 302.

[0157] Furthermore, the network management device can also save the information of the connection device connected to each radio frequency unit in the associated data, that is, the association relationship between the information of each radio frequency unit, the configuration information of the radio frequency unit, and the information of the connection device of each radio frequency unit can be saved in the associated data. Specifically, the information of each radio frequency unit in the associated data may include the identifier information of the radio frequency unit, the device type of the radio frequency unit, or the identifier information of the connection device connected to the radio frequency unit, etc. The identifier information of the radio frequency unit may include the ESN or name of the radio frequency unit, and the identifier information of the connection device may include the serial number or name of the connection device, etc.

[0158] For example, a possible associated data may be as Figure 5As shown, the associated data in this figure includes radio frequency unit information and configuration information. The radio frequency unit information is the information of radio frequency unit 0. The radio frequency unit information may include the device type, device identifier, characteristic attributes, and associated configuration of radio frequency unit 0. The configuration information is the configuration information corresponding to radio frequency unit 0. Among them, the device type is the type of radio frequency unit 0, such as AAU or RRU, etc.; the device identifier is the identifier of radio frequency unit 0. For example, the identifier of radio frequency unit 0 is the ESN0 of radio frequency unit 0; the characteristic attributes can be used to represent the topological relationship between radio frequency unit 0 and the connected device. The characteristic attributes may specifically include the identifier information of the connected devices such as the optical module and ALD connected to radio frequency unit 0. For example, it may include the identifier SN0 of the optical module 0 used by radio frequency unit 0; the associated configuration is used to establish the association relationship between the device information and the configuration information. The associated configuration includes the configuration name for identifying the configuration information of radio frequency unit 0. For example, if the name of the configuration information of radio frequency unit 0 is ID1, then the associated configuration in the information of radio frequency unit 0 can be filled with ID1, and the radio frequency unit information of radio frequency unit 0 is associated with the configuration information of radio frequency unit 0 through the associated configuration item. In the configuration information of radio frequency unit 0, the configuration information name is ID1; the system information is the system supported by radio frequency unit 0, such as LTE; the sector information is the sector where radio frequency unit 0 operates, such as sector 1. The configuration information may also include the address information of radio frequency unit 0, etc., Figure 5 which is not shown in the figure. Any configuration information about this radio frequency unit can be included in the configuration information in the associated data.

[0159] In addition, regarding the presentation form of the configuration information, it is not limited to the Figure 5 way shown in the above. In a possible case, the configuration information includes multiple copies, and each copy has a configuration name. Taking Figure 5 as an example, in the device information of the associated data, the associated configuration may include ID1 and ID2. The configuration information corresponding to ID1 may include the system information, sector information, etc. of radio frequency unit 0, and the configuration information corresponding to ID2 may include the address information of radio frequency unit 2, the information of the virtual local area network to which it belongs, etc.

[0160] In a possible implementation manner, the associated data can also be saved in the form of a mapping table. For example, the associated data can be as shown in Table 1.

[0161]

[0162] Table 1

[0163] Among them, each column in the mapping table can represent a type of information, and each row can represent the information corresponding to a radio frequency unit, including the ESN of the radio frequency unit, the ESN of one or more connected devices, and the configuration information.

[0164] The ESN of the radio frequency unit may be included in the site device column in this mapping table, such as the ESN1 of the radio frequency unit 0 in the embodiment of the present application.

[0165] Multiple columns of connection devices are also set in this mapping table. Each column may represent the information of a connection device, such as the SN of an optical module, an ALD, or an RGPS, etc. Each connection device may be set with one or two columns. For example, a radio frequency unit may be connected to two optical modules, and of course, it may also be connected to two ALDs or three optical modules, etc. The possible situations are not elaborated here one by one. Only taking the example of setting two columns of optical modules for each radio frequency unit is introduced.

[0166] The specific configuration information of the radio frequency unit can be included under the configuration information column. For example, configuration information 1 is the configuration information corresponding to the device identified as ESN1, and configuration information 2 is the configuration information corresponding to the device identified as ESN2, and so on. The configuration information 1 or configuration information 2, etc. can refer to the description in the foregoing step 302 or the foregoing Figure 5 Corresponding description, which will not be elaborated here. The foregoing associated data can be saved in the network management device in the network management system, or can be saved in an independently deployed data storage center. If the associated data is saved in the network management system, in the case where the network management system includes only one network management device, the associated data can be saved in this one network management device. In the case where the network management system includes multiple network management devices, the associated data can also be distributed and stored in the network management devices in the network management system. For example, in the case where the network management system includes multiple network management devices, each network management device can save the associated data including the configuration information of the radio frequency unit connected to it.

[0167] In a possible scenario, the associated data is saved in a distributed manner. For example, the network management system may include multiple network management devices, and the associated data can be saved in different distributed network management devices, and data intercommunication can be achieved between each network management device. When a certain network management device needs to obtain the associated data, it can use the intercommunication between each network management device to read the data saved by other nodes. For example, when network management device 0 needs to read the configuration information of radio frequency unit 0 from network management device 1, network management device 0 can send a request carrying the ESN or SN of radio frequency unit 0 to network management device 1, so as to request network management device 1 to query the configuration information corresponding to this ESN or SN from the saved associated data and send it to network management device 0.

[0168] 402. After replacing the device, the radio frequency unit 1 collects the information saved by the connection device.

[0169] In some scenarios, such as when the radio frequency unit 0 shows signs of aging, malfunction, or needs to be updated, the radio frequency unit can be replaced. After replacing the radio frequency unit 0 with the radio frequency unit 1, one or more connection devices that were connected to the radio frequency unit 0 can be reused. That is, after replacing the radio frequency unit 0 with the radio frequency unit 1, the one or more connection devices can continue to be connected to the radio frequency unit 1, or in other words, a connection can be established between the radio frequency unit 1 and the one or more connection devices.

[0170] For example, as Figure 6 shown, the radio frequency unit 0 is connected to one or more connection devices, such as optical modules, ALDs, or RGPSs. In addition, the connection devices can also include power supplies, UPSs, etc., which will not be enumerated here one by one. If the radio frequency unit 0 needs to be replaced, such as when the radio frequency unit 0 fails or ages and cannot communicate properly, or when hardware updates of the radio frequency units within the network are required, the operation and maintenance personnel can replace the radio frequency unit 0 with the radio frequency unit 1. The device type of the radio frequency unit 1 can be the same as or different from the device type of the radio frequency unit 0, which can be specifically determined according to the actual application scenario, and this application does not make any limitations in this regard.

[0171] After the radio frequency unit 1 is powered on, the radio frequency unit 1 can establish a connection with one or more connection devices, so that the radio frequency unit 0 can obtain the information saved by the one or more connection devices through the established connection. The information saved by the connection devices can be actively sent by each connection device to the radio frequency unit 1, or it can be that the radio frequency unit 1 actively requests the information saved by each connection device from each device, etc., which can be specifically determined according to the actual application scenario.

[0172] Specifically, the information of the connection devices can include but is not limited to the name, serial number, or other identifiers of the connection devices. For example, the SN of the optical module, the SN of the ALD, the serial number (serial number, SN) of the RGPS, the SN of the UPS, or the identifiers of other modules.

[0173] 403. The radio frequency unit 1 sends the first information to the network management device, including the information of the radio frequency unit 1 and the information saved by the connection devices.

[0174] Among them, the self - information of the radio frequency unit 1 can include the ESN, device type, name, or other identifiers of the radio frequency unit 1. The device type of the radio frequency unit 1 can specifically include types such as AAU, RRU, RRH, RFU, RU, etc.

[0175] After the radio frequency unit 1 is powered on, it can establish a connection with the network management device, and then based on the connection with the network management device, it can send its own identifier and the information saved by the connection devices to the network management device to request the configuration information of the radio frequency unit 1.

[0176] Generally, in the case of a station change, the newly replaced device may not have available configurations, so it is necessary to request configuration information from the network management device. In the implementation manner of this application, the new device can request the required configuration information based on the information of the connection device, which is equivalent to sending an accurate request voucher to the network management device.

[0177] When the radio frequency unit 1 sends the first information to the network management device, it can send the first information through the data interface with the network management device.

[0178] In a possible implementation manner, the radio frequency unit 1 can send the first information through interfaces such as a fronthaul interface, a common public radio interface (CPRI), or an enhanced common public radio interface (eCPRI).

[0179] Specifically, in a possible situation, the format of the first information can be the format of an Ethernet (ETH) frame. Figure 7 Taking the Ethernet II frame format as an example, the first information is located in the Ethernet II frame. Among them, the Ethernet II frame can include, but is not limited to, a destination media access control (DMAC) field, a source media access control (SMAC) field, a type (TYPE) field, a data (DATA) field, and a cyclic redundancy code (CRC) field. Specifically, the first information is located in the data field. As Figure 7 shown, the data field includes the first information. Further optionally, a flag bit can be placed in the field before the first part of the first information in the data field, and this flag bit can be used to locate the starting position of the first information. In addition, the Ethernet frame can also be an Institute of Electrical and Electronics Engineers (IEEE) 802.3 frame. Similar to the Ethernet II frame, the IEEE 802.3 frame also includes a data field, and the first information can also be located in this data field. Further optionally, a flag bit can also be placed before the starting position of the first information in the IEEE 802.3 frame, and no further drawing is shown.

[0180] Another possible situation is that the format of the first information is the format of a high-level data link control (HDLC) frame. Figure 8 Taking the HDLC frame format as an example, the first information is located in the HDLC frame. The HDLC frame may include, but is not limited to, a flag field, an address field, a control field, an information field, a frame check sequence (FCS) field, etc. The first information is included in the information field. Similarly, a flag bit may also be placed before the first information to locate the first information.

[0181] In addition, regardless of which of the above possible situations, the flag bit can have multiple placement forms. For example, a flag bit can be placed before the identifier of radio frequency unit 0, and a flag bit can also be placed before the identifier of one or more connection devices used by radio frequency unit 0 before replacement. In addition, the placement order of the identifier of radio frequency unit 0 and the identifier of the connection device (such as the identifier of an optical module) is not limited in this application.

[0182] 404. The network management device obtains the configuration information of radio frequency unit 1.

[0183] After the network management device receives the first information uploaded by radio frequency unit 1, it can obtain the information of radio frequency unit 0 or the information of at least one connection device carried in the first information, and obtain the configuration information corresponding to radio frequency unit 0 from the associated data based on the information of radio frequency unit 0 or the information of at least one connection device. Subsequently, the configuration information corresponding to radio frequency unit 1 is obtained based on the configuration information corresponding to radio frequency unit 0. For example, the configuration information corresponding to radio frequency unit 0 is used as the configuration information corresponding to radio frequency unit 1, or the configuration information corresponding to radio frequency unit 0 is adjusted to obtain configuration information that is more suitable for the configuration of radio frequency unit 1. Among them, the configuration information can refer to the description in the foregoing step 302 or Figure 5 The corresponding description will not be elaborated here.

[0184] Among them, the network management device can determine the configuration information associated with radio frequency unit 0 from the associated data based on the received first information. For example, in combination with the foregoing Figure 5 , the first information may carry the SN0 of the optical module connected to the replaced radio frequency unit 1. The network management device queries the radio frequency unit information of radio frequency unit 0 containing the SN0 from the associated data, further reads the associated configuration ID1 therein, and then reads the configuration information with the configuration name ID1 to obtain the configuration information of radio frequency unit 0.

[0185] After the network management device reads the configuration information of radio frequency unit 0, it can directly use the configuration information of radio frequency unit 0 as the configuration information of radio frequency unit 1, or after adjusting the configuration information of radio frequency unit 0, generate more suitable configuration information for radio frequency unit 1.

[0186] In a possible scenario, the configuration of radio frequency unit 0 can be used as the configuration of radio frequency unit 1, for example, directly sending the configuration of radio frequency unit 0 to radio frequency unit 1. For example, if radio frequency unit 0 fails and is replaced by radio frequency unit 1, and the replaced radio frequency unit 1 supports the same parameters as radio frequency unit 0, then radio frequency unit 1 can directly inherit the configuration of radio frequency unit 0, that is, the network management device can directly use the configuration of radio frequency unit 0 as the configuration of radio frequency unit 1, so as to obtain the configuration information of radio frequency unit 1.

[0187] In a possible scenario, radio frequency unit 1 also uploads the first information and the information of radio frequency unit 1, such as the ESN, name or device type of radio frequency unit 1. In this scenario, the network management device can determine the configuration information of radio frequency unit 0 from the associated data based on the received first information, and adaptively generate suitable configuration information for radio frequency unit 1. For example, when the models of radio frequency unit 0 and radio frequency unit 1 are different, the network management device can know the range of function parameters supported by radio frequency unit 0 and radio frequency unit 1 according to the models of radio frequency unit 0 and radio frequency unit 1, such as the supported power range or communication frequency range. For example, if radio frequency unit 1 supports more systems or sectors than radio frequency unit 0, at this time, the network management device can generate configuration information for radio frequency unit 1 with more systems or different sectors than radio frequency unit 0, so as to obtain the configuration information adapted to radio frequency unit 1 and send it to radio frequency unit 1.

[0188] 405. The network management device sends the configuration information to radio frequency unit 1.

[0189] After the network management device obtains the configuration information of radio frequency unit 1, it can send the configuration information to radio frequency unit 1.

[0190] In addition, after the network management device obtains the configuration information for radio frequency unit 1, it can update the associated data. For example, as Figure 9 shown, Figure 9 For the relevant description of the associated data shown, refer to the foregoing Figure 5 corresponding description. In this embodiment, the identifier ESN0 of radio frequency unit 0 in the association relationship can be updated to the identifier ESN1 of radio frequency unit 1. In addition, if the configuration information is updated, the data of the configuration information can also be updated accordingly. For example, if the system of the radio frequency unit is updated, the system of radio frequency unit 1 in the associated data can be updated.

[0191] 406. Radio frequency unit 1 performs configuration.

[0192] After the radio frequency unit 1 receives the configuration information, it configures the parameters of the radio frequency unit 1 based on the configuration information, so that the radio frequency unit 1 can operate normally in the communication network.

[0193] For example, the sector information in the configuration information of the radio frequency unit 1 may include information such as the frequency point, power, bandwidth, or direction angle of the sector. After the radio frequency unit 1 receives the configuration information, it can use the information carried in the configuration information to configure the frequency point, power, bandwidth, or direction angle and other parameters of the corresponding sector of the radio frequency unit 1, so as to implement the sector parameter configuration of the radio frequency unit 1.

[0194] Optionally, after the radio frequency unit 1 completes the configuration, it can also send a configuration confirmation message to the network management device. After the network management device confirms the configuration of the radio frequency unit 1, the subsequent communication process can be carried out.

[0195] Therefore, in the embodiment of the present application, the radio frequency unit 1 can use the information saved by the connection device to obtain the required configuration information. During the process of obtaining the configuration information, no manual or third-party participation is required, reducing the labor cost and realizing a more intelligent configuration of the radio frequency unit 1. And it can use the information saved by the connection device to more accurately distinguish whether the replaced device is a front-end or remote device, realizing a more accurate device configuration, avoiding configuration failures caused by information errors or large information errors, and improving the configuration success rate.

[0196] It can be understood that in the embodiment of the present application, the replaced radio frequency unit can obtain the information saved by the connection device of the radio frequency unit before replacement through the information of the radio frequency unit before replacement (such as the ESN of the radio frequency unit before replacement), so as to request the configuration information of the replaced radio frequency unit (such as: power, bandwidth, frequency point, etc.) from the network management device based on the information saved by the connection device of the radio frequency unit before replacement; for example, after the replaced radio frequency unit is powered on, it can report its own ESN and the SN of the surrounding interconnected connection devices, and the network management device searches according to these information to obtain the configuration information of the radio frequency unit 0, and then obtains the configuration information of the radio frequency unit 1 based on the configuration information of the radio frequency unit 0 and configures it into the radio frequency unit 1, thus completing the replacement of the radio frequency unit.

[0197] For example, for the method of planning the site opening data corresponding to the site by the site name and the ESN of the site device, after the device is powered on, it obtains the site opening data through the ESN number to open the base station, and the front-end installation personnel need to communicate with the back-end network management personnel about the ESN information of the installed site module. The network management personnel only associate the data after obtaining the ESN of the site device. The overall process requires a lot of manual interaction and is complex. In the method provided by the embodiment of the present application, the method of automatically obtaining the site opening data based on the information of the connection device (such as optical module / ALD / RGPS, etc.) solves the problem that manual intervention is required to obtain the site opening data during the base station opening process and the process is complex.

[0198] For another example, in the method provided by the embodiments of the present application for obtaining site opening data based on the location information of the site to be opened, the solution of obtaining site opening data based on the information saved by the connection device can accurately configure the replaced device and can also solve the problem that the front-end remote device cannot be accurately distinguished in the existing site opening configuration process.

[0199] In addition, in some possible scenarios, the data saved in the connection device may include the information of the connection device itself or the information written by Radio Frequency Unit 0. The process of writing the information to be backed up by Radio Frequency Unit 0 in the connection device before replacement is introduced in detail below.

[0200] Exemplarily, refer to Figure 10 , a schematic flowchart of a device configuration method further provided by the present application.

[0201] 1001. Radio Frequency Unit 0 writes backup data to the connection device.

[0202] To implement data backup, before Radio Frequency Unit 0 is replaced, when Radio Frequency Unit 0 is operating normally in the communication network, it can store the data to be backed up in the storage space of one or more connection devices.

[0203] The data to be backed up may include the information of Radio Frequency Unit 0 or all or part of the configuration information. The information of Radio Frequency Unit 0 may specifically include the ESN, name, or device type of Radio Frequency Unit 0, etc. The configuration information of Radio Frequency Unit 0 can refer to the description of the configuration information of the second device in the foregoing step 302, which will not be elaborated here.

[0204] For example, if a storage space is set in one or more connection devices, such as if a storage space is set in an optical module, and if the storage space is larger than the space occupied by the configuration information of Radio Frequency Unit 0, then Radio Frequency Unit 0 can directly write the configuration information in full amount to this storage space to achieve full amount backup of the configuration information. Another example is that if the storage space set in the connection device is smaller, such as smaller than the space occupied by the configuration information of Radio Frequency Unit 0, then Radio Frequency Unit 0 can write the information of Radio Frequency Unit 0 to this storage space, such as writing the ESN or device type (such as AAU, RRU, RRH, RFU, RU, etc.) of Radio Frequency Unit 0 to this storage space.

[0205] Furthermore, the specific backup data saved by the connection device can refer to the relevant descriptions in the foregoing step 301 or the foregoing step 403, which will not be elaborated here.

[0206] 1002. After Radio Frequency Unit 0 is replaced with Radio Frequency Unit 1, Radio Frequency Unit 1 reads the backup data from the connection device.

[0207] After the radio frequency unit 0 is replaced with the radio frequency unit 1, the radio frequency unit 1 can read the backup data saved by the connection device.

[0208] When the configuration information of the radio frequency unit 0 is saved in the storage space of the connection device, the radio frequency unit 1 can directly read the available configuration information from the storage space and perform configuration based on the read configuration information to more efficiently complete the device configuration.

[0209] If the information of the radio frequency unit 0 is saved in the storage space of the connection device, such as the ESN, name, or device type of the radio frequency unit 0, etc., the radio frequency unit 1 can request configuration information from the network management device based on the read information. The specific steps for the radio frequency unit 1 to request the configuration information of the radio frequency unit 1 from the network management device can refer to the Figures 3 to 9 corresponding description above and will not be elaborated here.

[0210] 1003. The radio frequency unit 1 writes new backup data to the connection device.

[0211] After the radio frequency unit 1 completes the configuration, it can also write new backup data to the storage space of the connection device. The new backup data can include the information of the radio frequency unit 1 or the configuration information of the radio frequency unit 1, so as to back up the information of the radio frequency unit 1. The information of the radio frequency unit 1 can include the ESN, name, or device type of the radio frequency unit 1, etc. The configuration information of the radio frequency unit 1 can refer to the description of the configuration information of the second device in step 302 above and will not be elaborated here.

[0212] Therefore, in the embodiments of the present application, when the connection device sets the storage space, the information of the radio frequency unit 0 before replacement can be backed up in the storage space, such as backing up the configuration information, identification information, or device type information of the radio frequency unit 0 before replacement. Thus, when the radio frequency unit 0 is replaced with the radio frequency unit 1, the radio frequency unit 1 can request the configuration information of the radio frequency unit 1 from the network management device by reading the information of the radio frequency unit 0 before replacement backed up in the storage space, so as to obtain the required configuration information more efficiently and accurately, and improve the configuration efficiency and accuracy of the new device.
