[0088] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.

[0089] In the description of this application, it should be noted that, unless otherwise clearly specified and limited, the term "and / or" in this article is only a description of the association relationship of associated objects, indicating that three relationships may exist. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this article, unless otherwise specified, generally indicates that the associated objects before and after are in an "or" relationship.

[0090] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, the elements defined by the sentence "comprise a ..." do not exclude the existence of other identical elements in the process, method, article or device including the elements.

[0091] In the prior art, the management server can only generate and manage the topology model of the basic base station, where the equipment in the basic base station is provided by the same manufacturer, but cannot generate and manage the topology model of the complex base station, where the equipment in the complex base station is provided by different manufacturers. Therefore, how to generate the topology model for the base station containing equipment from different manufacturers is an urgent problem to be solved.

[0092] The present application proposes a method and device for determining base station topology data, and a base station management system, which can generate the topology data of the base station and use the topology data to construct a topology model of the base station.

[0093] A method and device for determining base station topology data and a base station management system provided by the present application are introduced below in conjunction with the accompanying drawings.

[0094] In some embodiments, the equipment in the base station includes a baseband unit BBU, a radio frequency unit RRU, and an extension unit Hub. The connection between the equipment follows the following rules: 1. The baseband unit BBU can be directly connected to the radio frequency unit RRU; 2. The baseband unit BBU can be directly connected to the extension unit Hub; 3. The extension unit Hub can be directly connected to the radio frequency unit RRU; 4. The extension unit Hub can be directly connected to the extension unit Hub. In addition, the baseband unit is the highest level of equipment in the base station, and the baseband unit has management functions for the base station. The next level of the radio frequency unit cannot be connected to other devices. The next level of the extension unit is usually connected to other devices.

[0095] In some embodiments, Figure 2 This is an embodiment of a topology model of a base station, and the topology model of the base station can reflect the connection relationship between different devices. The base station includes a BBU, and the BBU is connected to n RRUs (RRU-a1 to RRU-an), and the BBU is connected to n Hubs (Hub-b1 to Hub-bn). Further, in Hub-b1 to Hub-bn, each Hub is connected to n RRUs and n Hubs respectively. Taking Hub-b1 as an example, Hub-b1 is connected to RRU-c1, RRU-c2, ..., RRU-cn, Hub-d1, Hub-d2, ..., Hub-dn respectively. And in Hub-d1 to Hub-dn, each Hub is connected to n RRUs respectively. Taking Hub-d1 as an example, Hub-d1 is connected to RRU-e1, RRU-e2, ..., RRU-en respectively. Taking Hub-bn as an example, Hub-bn is connected to RRU-f1, RRU-f2, ..., RRU-fn, Hub-g1, Hub-g2, ..., and Hub-gn respectively. In Hub-g1 to Hub-gn, each Hub is connected to n RRUs respectively. Taking Hub-g1 as an example, Hub-g1 is connected to RRU-h1, RRU-h2, ..., and RRU-hn respectively. The connection between Hubs can also be called "cascading".

[0096] further, Figure 2 The topological model can also be simplified to Figure 3 The BBU is connected to the RRU-1 and Hub-1 of the next level. Hub-1 is connected to the RRU-2 and Hub-2 of the next level. Hub-2 is connected to the RRU-3 of the next level.

[0097] In some embodiments, the communication protocol between BBU and RRU in the 4G era is the Common Public Radio Interface (CPRI). With the advent of the 5G era, due to the emergence of Massive MIMO (massive antenna technology), higher requirements are placed on data transmission, so the communication protocol between BBU and RRU has emerged as eCPRI (enhanced CPRI). Hub can support both CPRI and eCPRI. When actually establishing a base station, the communication protocols supported by different devices can be freely arranged and combined, so the network planning within the base station may be very complicated.

[0098] In some embodiments, considering the communication protocol between devices, Figure 3 For further details, see Figure 4As shown, the communication protocols between devices include eCPRI and CPRI, and the Hub can complete the conversion from eCPRI to CPRI. Referring to topology model 1, when the BBU supports eCPRI, the Hub-1 can complete the conversion from eCPRI to CPRI. If the northbound interface (the northbound interface is the interface connected to the upper-level device) of RRU-2 connected to the southbound interface (the southbound interface is the interface connected to the lower-level device) of Hub-1 supports CPRI, then CPRI is used between Hub-1 and RRU-2; if the northbound interface of Hub-2 connected to the southbound interface of Hub-1 does not support CPRI, then eCPRI is used between Hub-1 and Hub-2; if the northbound interface of RRU-3 connected to the southbound interface of Hub-2 supports CPRI, then CPRI is used between Hub-2 and RRU-3. Referring to topology model 2, it can be seen that the northbound interface of RRU-1 connected to the southbound interface of BBU supports eCPRI, the northbound interface of Hub-1 connected to the southbound interface of BBU supports eCPRI, the northbound interface of RRU-2 connected to the southbound interface of Hub-1 supports CPRI, the northbound interface of Hub-2 connected to the southbound interface of Hub-1 supports CPRI, and the northbound interface of RRU-3 connected to the southbound interface of Hub-2 supports CPRI. Referring to topology model 3, it can be seen that the northbound interface of Hub-1, the southbound interface of Hub-1, the northbound interface of RRU-1, the northbound interface of RRU-2, the northbound interface of Hub-2, the southbound interface of Hub-2, and the northbound interface of RRU-3 all support eCPRI, so all communications within the base station use eCPRI. Referring to topology model 4, when the BBU supports CPRI, the northbound interface of Hub-1, the southbound interface of Hub-1, the northbound interface of RRU-1, the northbound interface of RRU-2, the northbound interface of Hub-2, the southbound interface of Hub-2, and the northbound interface of RRU-3 all support CPRI, and CPRI is used for communication within the base station.

[0099] In some embodiments, see Figure 5As shown, the equipment in the base station includes: BBU, Hub1, Hub2, RRU1, RRU2, RRU3, RRU4, and the interfaces in the equipment can be further refined. The interfaces in the equipment can also be called optical ports, and the types of interfaces include: fronthaul port FH, backhaul port BH, and cascade port Cascade. The connection between the interfaces follows the following rules: 1. BBU and RRU only have fronthaul port FH; 2. Hub includes fronthaul port FH, backhaul port BH, and cascade port Cascade; among them, the backhaul port BH is connected to the cascade port Cascade in the upper-level Hub or to the fronthaul port FH in the upper-level BBU; the fronthaul port FH in the Hub can be connected to the fronthaul port FH in the lower-level RRU. Specifically, the fronthaul port FH1 in the BBU is connected to the backhaul port BH1 in the Hub1; the fronthaul port FH3 and the fronthaul port FH4 in the Hub1 are connected to the fronthaul port FH2 in the RRU1 and the fronthaul port FH1 in the RRU2 respectively; the cascade port Cascade2 in the Hub1 is connected to the backhaul port BH1 in the Hub2; the fronthaul port FH3 and the fronthaul port FH4 in the Hub2 are connected to the fronthaul port FH2 in the RRU3 and the fronthaul port FH1 in the RRU4 respectively. In addition, each interface can support eCPRI or CPRI, and the two connected interfaces support the same communication protocol.

[0100] In some embodiments, the correspondence between the interface number (Port Id) and the interface name (Port Name) of each interface is recorded in the interface list; wherein the last digit of the interface name is equal to the interface number; the English field in the interface name can represent the interface type, for example, eth represents the fronthaul port in the BBU / RRU, bh-eth represents the backhaul port in the Hub, fh-eth represents the fronthaul port in the Hub, and cas-eth represents the cascade port. The form of the interface list can be referred to as shown in Table 1.

[0101] Table 1

[0102]

[0103] In some embodiments, after the base station is established, that is, after the baseband unit BBU, the radio frequency unit RRU, and the extension unit Hub in the base station are connected at the physical level, the following steps are taken to establish a connection at the communication level:

[0104] S1: BBU and Hub are powered on and initialized. After the power-on and initialization are completed, they actively initiate a TCP / IP-based "connection establishment request" with the BBU.

[0105] S2: BBU monitors whether a "connection establishment request" is received;

[0106] S3: After the BBU monitors the "connection establishment request", the connection establishment process can be completed between the BBU and the Hub and RRU to achieve connection establishment at the communication level.

[0107] In some embodiments, after the BBU monitors the “connection establishment request”, the method further includes:

[0108] S1: BBU actively sends a query request for device information to RRU and Hub;

[0109] S2: After receiving the query request for device information, the RRU and Hub send their own device information to the BBU;

[0110] S3: After receiving the equipment information of the RRU and the Hub, the BBU obtains its own equipment information; the RRU equipment information, the Hub equipment information, and the BBU equipment information are aggregated together to form a base station equipment list.

[0111] In some embodiments, the management plane between the BBU and the Hub and RRU communicates using the NETCONF protocol. After the Hub and RRU dynamically allocate the fronthaul port IP based on the Dynamic Host Configuration Protocol (DHCP), they actively establish a NETCONF connection with the BBU.

[0112] In some embodiments, the base station device list is stored in the memory of the BBU in the form of a linked list. Each node in the base station device list corresponds to a device. The form of the node in the base station device list is as follows:

[0113]

[0114]

[0115] Among them, serial_number represents the device serial number, which is the unique identifier of the device;

[0116] mac_address indicates the hardware address (Mac address) of the device;

[0117] device_type indicates the device type, which includes BBU, RRU, and Hub.

[0118] if_proto_type represents a set of interface information;

[0119] port_name corresponds to the Port Name in Table 1 (Interface List), indicating the interface name;

[0120] proto_type indicates the communication protocol of the interface, which includes eCPRI and CPRI.

[0121] It should be noted that if_proto_type in the base station equipment list only records the fronthaul port information and / or cascade port information of the device, but does not record the backhaul port information. And because the device usually has multiple fronthaul ports / cascade ports, if_proto_type is also multiple groups. Furthermore, if_proto_type will record the information of the fronthaul port / cascade port of the device that is connected to the lower-level device and the information of the fronthaul port / cascade port that is not connected to the lower-level device.

[0122] In some embodiments, when the device type is BBU, Port Name records the interface name of the BBU fronthaul port, and proto_type records the communication protocol of the BBU fronthaul port;

[0123] When the device type is Hub, Port Name will record the interface name of the Hub front-end port and the interface name of the cascade port, and proto_type will record the communication protocol of the Hub front-end port and the communication protocol of the Hub cascade port;

[0124] When the device type is RRU, Port Name records the interface name of the RRU fronthaul port, and proto_type records the communication protocol of the RRU fronthaul port.

[0125] In some embodiments, when a new device is connected to the base station, the device information of the new device can be written into the base station device list in the following manner to update the base station device list:

[0126] S1: BBU sends a query request for device information to the new device (referred to as device A);

[0127] S2: After receiving the query request for device information, device A sends its own device information to the BBU; wherein the device information includes the device serial number, hardware address, device type, and interface information; the interface information includes the fronthaul port information and / or the cascade port information;

[0128] S3: The BBU receives the device information of device A, and adds the device information of device A as a new node to the end of the base station device list.

[0129] In some embodiments, after the connection establishment process between the BBU and the Hub and RRU is completed, the BBU will monitor the connection status of the Hub and RRU in real time. If it is detected that a Hub and / or RRU is disconnected, the BBU will actively find the node corresponding to the disconnected device from the base station device list and delete the node corresponding to the disconnected device from the base station device list.

[0130] In some embodiments, each BBU and Hub has a corresponding routing table. Since the RRU does not provide Ethernet packet forwarding function, the RRU does not have a routing table. The BBU can query the BBU's own routing table and the Hub's routing table.

[0131] In some embodiments, the routing table of a device (referred to as device B) is in the form of:

[0132]

[0133] in, <routing-table> Indicates the start mark of the routing table.< / routing-table> Indicates the end mark of the routing table;

[0134] <route> and< / route> A group of information about associated devices directly connected to device B is recorded;

[0135] <address> and< / address> The hardware address of the device connected to device B is recorded between the two devices; the hardware address is also called Mac (Medium / Media Access Control) address or media access control address. Each device has a unique hardware address.

[0136] <port-index> and< / port-index> The interface number (corresponding to the Port Id in the interface list) of the interface connected to the device pointed to by the above hardware address in device B is recorded.

[0137] In this application, the current device is referred to as the "local side" and the device connected to the current device is referred to as the "opposite side". <address> and< / address> The content recorded between them is also called "the hardware address of the other end". <port-index> and< / port-index> The content recorded between them is also called "interface number on this side".

[0138] by Figure 5 Taking Hub1 in the example, the routing table of Hub1 can be as follows:

[0139]

[0140] by Figure 5 Taking the BBU in the example, the routing table of the BBU can be in the following form:

[0141]

[0142] The present application proposes a method for determining base station topology data, which is applied to a baseband unit in a base station. Figure 1 As shown, the method specifically includes the following contents.

[0265] In some embodiments, when it is determined that the device type of the third device includes both a radio frequency unit and an extension unit, or only includes an extension unit, the above steps are repeated to generate the first topology data of the third device and determine the next-level device according to the routing table of the third device until the device type of the next-level device only includes a radio frequency unit.

[0266] Based on the above embodiments, the first topology data can be constructed for each device in the base station. The northbound interface field in the first topology data can characterize the connection relationship between the device and the upper-level device, and the southbound interface field in the first topology data can characterize the connection relationship between the device and the next-level device. Therefore, the topology model of the base station can be accurately constructed using the first topology data.

[0267] In some embodiments, after determining that the second device is a second radio frequency unit, the method further includes:

[0268] S1: Determine, from the second interfaces, an interface connected to the second radio frequency unit as a fronthaul interface;

[0269] S2: Determine the interface name of the fronthaul port from the base station device list;

[0270] S3: Write the interface name of the fronthaul port into the southbound interface field in the first topology data of the first extension unit.

[0271] For example, taking Table 1 as an example, according to the routing table of the first extension unit, it can be determined that interface 1 is connected to the second radio frequency unit, then interface 1 belongs to the fronthaul port; further, in the base station equipment list, find the fronthaul port whose last digit is equal to 1, and determine its corresponding interface name Port Name "fh-eth1" as the interface name of the fronthaul port; write "fh-eth1" into the blank field 7 in the southbound interface field to further improve the first topology data.

[0272] In some embodiments, when the first extension unit is connected to the second extension unit, the interface connected to the second extension unit can be determined from the second interface of the first extension unit, and its interface type is a cascade port; further, in the interface list or the base station equipment list, according to the interface number of the cascade port, the corresponding interface name is found; finally, the interface name corresponding to the cascade port is written into the blank field 7 in the southbound interface field of the first topology data of the first extension unit.

[0273] In some embodiments, when the first extension unit is connected to the baseband unit, the interface connected to the baseband unit can be determined from the second interface of the first extension unit, and its interface type is a backhaul port; further, in the interface list, according to the interface number of the backhaul port, find out the corresponding interface name; finally, write the interface name corresponding to the backhaul port into the blank field 7 in the northbound interface field of the first topology data of the first extension unit.

[0274] Based on the above embodiment, for the expansion unit, the output interface type is determined according to the device types of the two connected devices, and then the output interface name is determined according to the interface type and interface number, and the interface name is written into the corresponding position in the first topology data (blank field 7) to further improve the first topology data.

[0275] It should be noted that, since there is only a fronthaul port FH in the baseband unit, for the baseband unit, the name of the output interface can be determined only according to the interface number.

[0276] The present application also proposes a base station management system, which includes a base station and a management server; the management server is used to monitor and manage the operation of the base station in real time; the management server is also used to build a topology model of the base station according to the target topology data of the base station.

[0277] In some embodiments, when there is a fault or risk in the base station, the extension unit / radio unit in the base station will actively report the extension unit alarm information / radio unit alarm information to the baseband unit, and the baseband unit will also obtain its own alarm information (baseband unit alarm information). The baseband unit then combines the extension unit alarm information, the radio frequency unit alarm information, and the baseband unit alarm information to form the base station alarm information, and reports the base station alarm information to the management server.

[0278] In some embodiments, the base station alarm information is divided into high-level alarm information (Critical), intermediate alarm information (Major), and low-level alarm information (Minor); among them, the condition for generating high-level alarm information is that the device loses synchronization lock; the condition for generating intermediate alarm information is that the device has no external synchronization source; the condition for generating low-level alarm information is that the device temperature is too high.

[0279] In some embodiments, the management server pre-associates and configures the service terminal; the service terminal is a terminal held by a service personnel (e.g., a base station operation and maintenance engineer, a programmer). The management server pre-associates and configures the telephone number and / or email address of the service terminal, and pre-associates and configures the push conditions:

[0280] 1. When the push condition is "all push", the management server will actively push all base station alarm information to the service terminal via SMS / email;

[0281] 2. When the push conditions are medium or high level, the management server will actively push the high level alarm information and medium level alarm information to the business terminal via SMS / email;

[0282] 3. When the push condition is advanced push, the management server will actively push the advanced alarm information to the business terminal via SMS / email.

[0283] In some embodiments, the base station alarm information may include: base station serial number, alarm detailed description information, base station location information, etc. The base station alarm information may also be customized by business personnel.

[0284] In some embodiments, when the base station failure is eliminated, the baseband unit may report the alarm cancellation information to the management server, and the management server actively pushes the alarm cancellation information to the service terminal via SMS / email.

[0285] Based on the above embodiments, business personnel can freely and flexibly configure push conditions. When the push conditions are met, the management server can actively push base station alarm information to the business terminal of the business personnel, helping the business personnel to timely monitor the operating status of the base station and detect base station failures in a timely manner.

[0286] In some embodiments, the baseband unit sends the target topology data to the management server. After receiving the target topology data, the management server parses the target topology data according to the following method to draw a topology model, where the topology model is a tree structure:

[0287] S1: Find a device whose device type is BBU from the target topology data and use it as the root node of the topology model;

[0288] S2: according to the southbound interface field of the root node and the device serial number of the root node, associate with the northbound interface field of the second-level child node, that is, find the northbound interface field with the same device serial number as the root node to locate the second-level child node, and draw the second-level child node connected to the root node; wherein the second-level child node includes at least: device type and device serial number;

[0289] S3: According to the southbound interface field of the second-level subnode and the device serial number of the second-level subnode, the northbound interface field of the third-level subnode is associated, and the third-level subnode connected to the second-level subnode is drawn; the above steps are repeated until the type of the subnodes is all RRU, then the drawing is stopped to obtain the topology model.

[0290] In some embodiments, the topology model of the base station can refer to Figure 6 As shown. Interface 1 in the baseband unit is connected to the first RF unit, interface 2 in the baseband unit is connected to interface 1 in the first extension unit, and interface 2 in the first extension unit is connected to the second RF unit. It should be noted that since the routing table of the baseband unit only records that interface 1 of the baseband unit is connected to the first RF unit, and the first RF unit does not have a routing table, the interface number of the interface in the first RF unit connected to the baseband unit cannot be determined in the topology model. It can only be determined that the interface in the first RF unit belongs to the fronthaul port, and the fronthaul port is marked as X1. Similarly, the interface number of the interface in the second RF unit connected to the first extension unit cannot be determined in the topology model. It can only be determined that the interface in the second RF unit belongs to the fronthaul port, and the fronthaul port is marked as X2.

[0291] In some embodiments, the target topology data sent by the baseband unit to the management server also carries the base station serial number; accordingly, the topology model also has the base station serial number. The base station serial number, the base station, and the topology model of the base station correspond one to one.

[0292] In some embodiments, when the equipment in the base station changes, for example, when a new device is connected, the baseband unit updates the base station equipment list, adds the information of the newly connected device to the base station equipment list, and then generates updated target topology data based on the updated base station equipment list and routing table, and sends the updated target topology data to the management server. The management server regenerates the topology model based on the updated target topology data.

[0293] In some embodiments, when the equipment in the base station changes, for example, when the connected equipment is disconnected, the baseband unit updates the base station equipment list, deletes the information of the disconnected equipment from the base station equipment list, and then generates updated target topology data based on the updated base station equipment list and routing table, and sends the updated target topology data to the management server. The management server regenerates the topology model based on the updated target topology data.

[0294] In some embodiments, the baseband unit is also used to obtain the location information of the base station, for example, the latitude and longitude information of the base station is obtained as the location information through satellite positioning technology, and the location information is sent to the management server, and the location information also carries the base station serial number. The management server matches the location information with the topology model according to the base station serial number, and then marks the topology model that matches the location information on the map according to the location information.

[0295] Furthermore, the base station management system further includes a display terminal, which is used to display the marked map.

[0296] Based on the above embodiments, business personnel can intuitively grasp the location information of base stations.

[0297] In some embodiments, see Figure 7 As shown, the management server receives the first target topology data, the second target topology data, the third target topology data, the first location information, the second location information, and the third location information, wherein the first target topology data carries the base station serial number 1, the second target topology data carries the base station serial number 2, the third target topology data carries the base station serial number 3, the first location information carries the base station serial number 1, the second location information carries the base station serial number 2, and the third location information carries the base station serial number 3. The management server generates a first topology model carrying the base station serial number 1 according to the first target topology data, generates a second topology model carrying the base station serial number 2 according to the second target topology data, and generates a third topology model carrying the base station serial number 3 according to the third target topology data. The management server successfully matches the first location information with the first topology model, marks the first positioning symbol in the map according to the first location information, associates the first positioning symbol with the first topology model, and marks the base station 1.

The third positioning symbol is associated with the third topology model, and base station 3 is marked. The display terminal displays the marked map. The map is an electronic map, and the map may include information such as buildings (building 1, building 2, building 3, building 4), roads, etc. The display terminal also includes a topology model display area. When the business personnel clicks on the base station, the display terminal displays the topology model corresponding to the base station.

[0298] In some embodiments, the display terminal may also highlight the base station that generates the base station alarm information. Figure 8 As shown, when base station 1 generates base station alarm information, the topology model of base station 1 is highlighted. Furthermore, different colors can be used to represent different types of base station alarm information. For example, red is used to represent base stations with high-level alarm information, orange is used to represent base stations with medium-level alarm information but not high-level alarm information, blue is used to represent base stations with only low-level alarm information, green is used to represent base stations without base station alarm information, and gray is used to represent base stations that have not been started.

[0300] In some embodiments, when constructing a topology model, the interface name, interface number, and communication protocol in the target topology data can be associated with the topology model. When a business person clicks on an interface, the display terminal will display the corresponding interface name, interface number, and communication protocol. In the topology model, different line segments can be used to represent the communication protocol used between two interfaces.

[0301] In some embodiments, the baseband unit may also report interface data (e.g., interface connection status, interface rate, interface type, interface number, interface name, interface IP, subnet mask, transmission distance, etc.) to the management server, and the management server associates the interface data with the interface in the topology model. When the business personnel clicks on the interface, the display terminal displays the corresponding interface data.

[0302] In some embodiments, the baseband unit may also report device operation information (e.g., manufacturer, hardware version number, software version number, device code, device activation date, etc.) to the management server, and the management server associates the device operation information with the device in the topology model. When the business personnel clicks on the device, the display terminal displays the corresponding device operation information.

[0303] In some embodiments, the baseband unit may also report the cell configuration information corresponding to the base station to the management server, and the management server associates the cell configuration information with the topology model. When the business personnel clicks on the topology model, the display terminal displays the cell configuration information.

[0304] Based on the above embodiments, the electronic map, topology model and real-time base station alarm information push can be combined to jointly realize the management and information display of the topology model under the hybrid complex networking, so that the content displayed by the topology model is richer and the base station management is more real-time. This application uses SMS or email to actively notify the business personnel of the base station alarm information. Compared with the solution in the prior art that the business personnel must actively log in to the base station maintenance web page to view the base station alarm information, this application can ensure that the base station fault is discovered in time. The topology model can truly reflect the physical connection relationship of the base station equipment, the baseband unit reports the latest target topology data in real time, and the management server refreshes the base station topology changes in real time according to the latest target topology data to generate the latest topology model. It can also further associate and display the device operation information, interface data, hardware address, device type, device serial number, communication protocol and other information. Through map annotation, the location and health status of the base station can be intuitively displayed, helping business personnel to quickly locate the location of the faulty base station, which can greatly reduce the difficulty of business personnel managing the base station.
