Description

Technical Field

[0002] With the development of science and technology and economy, communication technology has developed rapidly, people have higher and higher requirements for network quality, and the demand for deep network coverage has increased. The construction of indoor distribution systems has also become increasingly intensive. The indoor distribution system is aimed at indoor user groups and is used to improve the mobile communication environment in buildings. It uses indoor antenna distribution systems to evenly distribute the signals of mobile base stations in every corner of the room, thereby ensuring that the indoor area has ideal signal coverage. It is an important supplement to outdoor stations.

[0003] The existing fault location of indoor cells depends on the network management system. When the network management system finds that the overall signal strength of the indoor cell is lower than the manually set signal threshold parameter, it can be determined that the cell has a network fault. As for the hidden faults in some areas of the floor, they can only be learned through the complaint channel. In the existing technology, maintenance and complaint handling personnel cannot accurately locate the specific floor and specific location of the floor where the fault is located. They need to check the coverage position of the entire indoor distribution system RRU, feeder, antenna, coupling device, and check and test each floor to find the distribution system fault location. Fault troubleshooting and positioning are difficult, costly, and inefficient.

[0004] It can be seen that there is an urgent need for a processing method that can enhance the accuracy of indoor network fault diagnosis. Summary of the invention

[0024] In order to make the purpose, technical solution and advantages of the present application clearer, the technical solution of the present application will be clearly and completely described below in combination with the specific embodiments of the present application and the corresponding drawings. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present application.

[0025] The full name of the indoor distribution system is the indoor signal distribution system, and the cell covered by the indoor distribution system is called the indoor distribution cell. The indoor distribution system can solve the problem of no mobile signal in confined spaces such as elevators and basements. The indoor distribution system uses an indoor antenna distribution system to evenly distribute the signal of the mobile base station to every corner of the room, thereby ensuring that every area in the room can achieve ideal signal coverage, improving the call quality in the building, and increasing the mobile phone connection rate, thereby enhancing the mobile user experience. By monitoring the indoor distribution system for faults and discovering and solving problems in a timely manner, the network quality of the indoor distribution cell can be guaranteed. Generally, the specific structure of the indoor distribution system is as follows: Figure 1 As shown, it mainly includes: base station equipment, multiple indoor devices connected to the base station equipment (for example, indoor antennas), multiple indoor cells determined by the signal coverage range of the indoor devices, buildings covered by the base station equipment signal, servers and terminal devices located in the buildings. Figure 1 Introduce the working principle of the room distribution system:

[0026] Among them, the building is composed of multiple floors, multiple terminal devices can be distributed on different floors of the building, and multiple indoor devices can be distributed in different areas of different floors of the building, and then multiple indoor cells composed of multiple indoor devices can cover different areas of the building; the terminal devices can be smart phones, tablets, laptops, desktop computers, TVs, etc.; the base station equipment is also called a indoor base station, which is a micro base station, which can provide a wireless network for terminal devices in multiple indoor cells of the target building. The terminal equipment accesses the wireless network of the base station equipment, so that it can access the server and realize Internet access and other services.

[0027] Based on the above-mentioned room-divided system, the technical solutions provided by each embodiment of the present application are described in detail below in conjunction with the accompanying drawings.

[0028] An indoor distributed system fault detection method provided in an embodiment of the present application is used to solve the problem that the existing indoor distributed system fault detection method cannot accurately locate the fault area and has low fault location efficiency due to the single indoor distributed fault acquisition channel.

[0029] The executor of the indoor distributed system fault detection method provided in the embodiment of the present application may be, but is not limited to, at least one of an indoor distributed server, a call quality monitoring server, a network operation and maintenance server, and a fault analysis server; in addition, the executor of the method may also be an application (Application, APP) running on these servers or the system itself.

[0030] For ease of description, the following takes the method being performed by a fault detection system as an example to introduce the implementation of the method. It is understandable that the method being performed by a fault detection system is only an exemplary description and should not be understood as a limitation on the method.

[0031] The specific implementation flow chart of the indoor distributed system fault detection method provided in this application is as follows Figure 2 As shown, it mainly includes the following steps:

[0032] Step 11, generating a three-dimensional building indoor distribution site distribution model according to the acquired building indoor distribution system site data and building data;

[0033] In one embodiment, the fault detection system can obtain the building's indoor distributed system site data by querying pre-saved indoor distributed system design data and design drawings. Specifically, the acquired building's indoor distributed system site data may include: floor antenna location map, elevator antenna location map, basement antenna location, radio frequency remote unit (Remote Radio Unit, RRU) installation location and other specific locations of equipment installation, and network engineering parameter information such as the indoor distributed cell (Cell Global Identity, CGI) used by the building.

[0034] In addition, the fault detection system can obtain building data by querying pre-saved building architectural design data and design drawings. Specifically, the acquired building data may include: the location of the building (i.e. the longitude and latitude of the building), building dimensions (length, width and height) and building floor heights.

[0035] The fault detection system uses the acquired building distributed system site data and building data to model the building using 3D modeling software (for example, Revit software) to obtain a building information model (Building Information Modeling, BIM). Then, the BIM data of the building is exported from the Revit software, and the BIM data is imported into the Unreal 5 engine to obtain an Unreal building model, establish a building equipment coding standard, map and code the distributed equipment in the building, and obtain the distributed equipment coding data. The OPC-UA technology is used to build a data interaction structure. Based on the distributed equipment coding data, the internal data of the building is mapped to the Unreal building model to obtain the digital twin model corresponding to the building, which is used as a 3D building distributed site distribution model for subsequent building distributed system fault detection.

[0036] Among them, OPC-UA is a standardized technical framework that uses Internet integration technology and is not dependent on a specific operating system or hardware platform. OPC-UA can run in different environments, such as Windows, Linux, and embedded systems, and has independence, security, scalability, and modelability. Through information modeling, OPC-UA supports adding new objects and functions to the address space without changing existing programs or services. OPC-UA provides a rich information model that can represent various types of data and objects and supports modeling of complex structures and hierarchies. This enables OPC-UA to integrate data from different sources and formats to meet the needs of digital twin model data mapping and improve data interoperability and reusability. OPC-UA not only supports data access, but also provides advanced functions such as alarm and event processing, historical data storage, and complex data processing, which improves the intelligence of the digital twin model and the ability to control the building. The building control module includes a digital twin model and controls the building based on the digital twin model.

[0037] It should be noted here that the above scheme is only an exemplary description of the modeling method of the three-dimensional building indoor distributed site distribution model. In addition to the above modeling method, the embodiment of the present application can also use other modeling methods to generate a three-dimensional building indoor distributed site distribution model. The embodiment of the present application does not specifically limit the specific modeling scheme for generating a three-dimensional building indoor distributed site distribution model.

[0038] Step 12: determining the distribution information of the terminal in the three-dimensional building room distribution site distribution model according to the acquired terminal measurement report MR data;

[0039] It should be noted here that since the 5G network is currently unable to collect the Minimization of Drive Tests (MDT) data of the terminal, it can only determine the distribution position of the terminal in the three-dimensional building indoor site distribution model by collecting the Measurement Report data (MR data) reported by the terminal.

[0040] Among them, MR data is a measurement report generated when a user uses a mobile device to make a call, which records the user's cell location information, mobile phone transmission power, cell network quality and other information. These data are collected by the operator's base station and output as a Cell Trace Record file through the operational support system (OSS). In an embodiment of the present application, the measurement report MR data obtained may specifically include the following data: the CGI of the indoor cell occupied by the terminal, the longitude and latitude of the terminal, the reference signal received power (RSRP) of the terminal, and the current height of the terminal.

[0041] In the embodiment of the present application, the fault detection system can determine the floor distribution information of the terminal devices in the building and the specific area distribution information on the floor through the MR data uploaded by the terminal.

[0042] In the embodiment of the present application, the fault detection system can determine the floor distribution information and floor area distribution information of the terminal respectively according to the following sub-steps, specifically including:

[0043] Solution a, determine the floor distribution information of user terminals in the three-dimensional building indoor site distribution model in the building:

[0044] Sub-step 12-1-1, determining the minimum height data uploaded by the terminal corresponding to the building room subsystem;

[0045] In an embodiment of the present application, the fault detection system can obtain all user terminals connected to the current building base station device and receive MR data uploaded by these user terminals, and then determine the minimum height data uploaded by all terminals connected to the building base station device based on the obtained MR data.

[0046] Sub-step 12-1-2, determining first height data of the terminal in the building according to the height data corresponding to the terminal and the minimum height data;

[0047] It should be noted here that since some buildings are not built from sea level, for example, the first floor of some buildings corresponds to an altitude of 100 meters. In this case, when determining the specific floor corresponding to the equipment in the building, it is necessary to subtract the building's own construction altitude. For example, in the above example, when determining the height of each terminal device in the building, it is necessary to subtract 100 meters.

[0048] Determine the height data uploaded by the terminal on the floor to be identified, calculate the height difference between the height data and the minimum height data, and then determine the height data of the terminal to be identified in the building. Specifically, in the embodiment of the present application, the height of the terminal device in the building can be calculated according to the following formula [1]:

[0049] F n h=Eh (max) -Eh (min) [1]

[0050] Among them, F n h is the height of the terminal equipment in the building, Eh (max) Eh is the altitude data uploaded by the terminal device through MR data. (min) It is the minimum height data uploaded by all terminals connected to the building base station equipment.

[0051] Sub-step 12-1-3, determining the floor height data of the building according to the building data;

[0052] Sub-step 12-1-4, determining the floor distribution information of the terminal in the three-dimensional building indoor station distribution model according to the first height data and the floor height data.

[0053] By dividing the height of the terminal device in the building determined by executing step 12-1-2 by the floor height, the floor distribution information of the terminal device in the building can be determined.

[0054] Through the above sub-steps, the fault detection system can determine the floor distribution information of all user terminals connected to the current building base station equipment in the building, and then determine the user terminal equipment corresponding to each floor in the building through data clustering, and then accurately determine the operation status of the corresponding indoor equipment on the floor through the connection and communication status of the user terminal equipment belonging to the same floor.

[0055] In addition, it should be noted that in actual use, different indoor equipment (such as antennas) may be installed on the same floor, and each antenna has a corresponding signal coverage range. In the embodiment of the present application, in addition to determining the operating status of the indoor equipment on each floor, it is also necessary to further determine the operating status of the indoor equipment corresponding to each area of ​​the floor.

[0056] In an embodiment of the present application, the fault detection system can determine the signal coverage range of each indoor device according to the installation location of the indoor device, and then cluster the user terminal devices on each floor according to the corresponding signal coverage range of each indoor device, and obtain the user terminal devices within the signal coverage range of each indoor device, and then accurately determine the operation status of the indoor device corresponding to the specific area of ​​the floor through the connection communication status of the user terminal devices belonging to the same signal coverage range of the indoor device.

[0057] In one implementation, the fault detection system may determine the floor area distribution information of each terminal device according to the following sub-steps, including:

[0058] Sub-step 12-2-1, obtaining MR data uploaded by the terminal corresponding to the building room subsystem;

[0059] In the embodiment of the present application, according to the processing result of executing the above sub-step 12-1-4, the fault detection system can obtain the MR data corresponding to the terminal equipment on each floor according to the floor.

[0060] Sub-step 12-2-2, determining the longitude and latitude data corresponding to each terminal device on the floor according to the MR data;

[0061] Sub-step 12-2-3, determining the floor area distribution information of the terminal in the three-dimensional building indoor station distribution model based on the latitude and longitude data and the building data.

[0062] Specifically, in an embodiment of the present application, the fault detection system can determine the floor area distribution of each terminal device on the floor according to the following method, including: determining the indoor antenna position data corresponding to each floor in the three-dimensional building indoor site distribution model according to the building indoor distributed system site data; dividing each floor of the three-dimensional building indoor distributed site distribution model into regions according to the indoor distributed antenna position to obtain floor partitions; determining the floor partition corresponding to the terminal according to the latitude and longitude data, and obtaining the floor area distribution information of the terminal in the three-dimensional building indoor distributed site distribution model.

[0063] In one embodiment, the fault detection system can obtain the longitude and latitude of the polygons that constitute the building area, determine the longitude and latitude reported by each user terminal device, calculate the distance between the building polygon boundary and the longitude and latitude of the user terminal, and select the building polygon corresponding to the minimum distance as the floor area described by the user terminal device on that floor.

[0064] Through the above sub-steps, the fault detection system can determine the floor area distribution information corresponding to the terminal equipment on each floor, and then cluster the terminal equipment on each floor according to the floor area distribution information, so as to determine the user terminal equipment corresponding to each floor area in the floor. Since the floor area is determined according to the indoor antenna coverage position in the floor, if there is a fault in the indoor equipment in the floor area, then the terminal data collected in the floor area will also be abnormal. The accuracy of locating the fault position is greatly improved, the time for troubleshooting and handling the fault is greatly shortened, and the timeliness is greatly improved.

[0065] Step 13, based on the MR data, fault identification is performed on the building room subsystem;

[0066] It should be noted here that the method provided in the embodiment of the present application is mainly for fault detection in buildings with built indoor network. However, special locations in the building, such as windows, are more likely to occupy outdoor macro station signals. In order to avoid the influence of outdoor macro station signals on fault detection results, in the embodiment of the present application, before fault identification, the received MR data must be filtered to remove the surrounding macro station signals and only retain the indoor network signals. In the embodiment of the present application, the full CGI obtained by measurement can be compared with the indoor CGI in the engineering parameters, and the non-indoor CGI can be eliminated based on the number of MR sampling points.

[0067] In order to accurately identify faults of each room-based device in the building, in the embodiment of the present application, the fault detection system can cluster each terminal device according to the distribution information corresponding to each user terminal device determined by executing the above step 12, obtain the terminal devices in each area of ​​each floor, and then identify faults in the designated area of ​​the floor according to the MR data uploaded by the terminal devices in the area of ​​the floor. Specifically, in the embodiment of the present application, the fault detection system can identify faults according to the following method, including: clustering the acquired MR data according to the distribution information to obtain floor partition MR data; and identifying faults of the room-based system of the building according to the floor partition MR data.

[0068] It should be noted here that when the indoor equipment in the building is operating normally, the changes in the various detection indicators in the MR data uploaded by the user equipment are generally stable. However, when a certain indoor equipment has a fault, the changes in the various detection indicators in the MR data uploaded by the user terminal connected to the indoor equipment may fluctuate abnormally. Therefore, in an embodiment of the present application, the fault detection system can collect MR data of terminal devices in each floor area according to a preset detection cycle, and compare the various indicators in the MR data in the detection cycle with the indicators of the historical cycle in the floor area, and then determine whether there are abnormalities in the various indicators in the current detection cycle based on the comparison results, and then judge whether there is a fault in the indoor equipment in the floor area.

[0069] In one embodiment, the fault detection system can specifically perform fault identification according to the following method, including: obtaining floor partition MR data within a current detection cycle according to a preset fault detection cycle; obtaining average floor partition MR data within a historical detection cycle; and identifying faults in the building room partition system based on the floor partition MR data within the current detection cycle and the average floor partition MR data.

[0070] In one implementation, the fault detection system may perform fault detection on the building room subsystem according to the above fault identification method and the following dimensions, including:

[0071] 1. Reference Signal Received Power (RSRP) detection:

[0072] Assuming that the RSRP in a certain floor area during the current detection cycle is a null value, or the difference between the RSRP collected in multiple historical detection cycles exceeds a preset threshold, it can be determined that the indoor equipment corresponding to the floor area is faulty.

[0073] 2. Signal to Interference plus Noise Ratio (SINR) detection:

[0074] According to the RSRP detection results, if the difference between the SINR in the current detection cycle and the SINR collected in the historical detection cycle exceeds the preset threshold, it can be determined that the SINR of the floor area is reduced due to poor coverage, and there is a fault in the indoor equipment corresponding to the floor area.

[0075] 3. User number detection:

[0076] Assuming that the number of users in a certain floor area during the current detection cycle is null or 0, it can be determined that there is a fault in the indoor distribution equipment corresponding to the floor area.

[0077] 4. MR sampling point quantity detection:

[0078] Assuming that the MR sampling point in a certain floor area during the current detection cycle is null or 0, it can be determined that the room distribution equipment corresponding to the floor area is faulty.

[0079] 5. MR weak coverage ratio detection:

[0080] Specifically, when the difference between the MR weak coverage ratio in a certain floor area in the current detection cycle and the MR weak coverage ratio collected in the historical detection cycle exceeds a preset threshold, it can be determined that there is a fault in the indoor equipment corresponding to the floor area.

[0081] 6. 5G duration detection:

[0082] Specifically, when the difference between the 5G duration residence instance in a certain floor area during the current detection cycle and the 5G duration residence instance collected during the historical detection cycle exceeds a preset threshold, it can be determined that there is a fault in the indoor equipment corresponding to the floor area.

[0083] Step 14, when a distributed indoor system fault is identified by executing step 13, a fault point corresponding to the distributed indoor system fault is marked on the three-dimensional building distributed indoor site distribution model according to the distribution information;

[0084] In an embodiment of the present application, in order to better reflect the distribution of faulty indoor distributed equipment in a three-dimensional building indoor distributed site distribution model, in one implementation, the fault detection system can render the fault area on the three-dimensional building indoor distributed site distribution model according to preset KPI indicator rendering rules.

[0085] In the embodiment of the present application, the KPI indicator rendering rule includes two pre-set variables: variables i and Project, and a constant r.

[0086] Among them, the variable i represents the number of times the indicator is rendered in segments, i = (1, 2, 3, 4, ..., n); the constant r represents the initial rendering number of each indicator, which defaults to 1; Project represents the KPI indicator to be tested, which may include: RSRP, SINR, number of MR sampling points, number of users, MR weak coverage ratio and other indicators.

[0087] In the embodiment of the present application, the preset KPI indicator rendering rule can be shown as the following formula [2]:

[0088]

[0089] In an embodiment of the present application, the fault detection system can use digital twin technology to visualize the fault location process and result data in a three-dimensional building room site distribution model through a rendering mechanism. By visualizing the network quality, the user's ability to communicate and understand the network is enhanced, which helps to improve the accuracy of problem location, early detection and early resolution, and reduce network quality caused by equipment problems.

[0090] By adopting the indoor distributed system fault detection method provided in the embodiment of the present application, when fault detection is performed on the indoor distributed system of a building, in order to avoid the problem of inaccurate positioning of the faulty equipment, a three-dimensional building indoor distributed site distribution model can be first generated based on the acquired building indoor distributed system site data and building data, and the distribution information of the terminal in the three-dimensional building indoor distributed site distribution model can be determined based on the acquired terminal measurement report MR data. Then, according to the distribution information of the MR data in the three-dimensional building indoor distributed site distribution model, the fault of the building indoor distributed system can be identified according to the building floor partition, and when the indoor distributed system fault is identified, the fault point corresponding to the indoor distributed system fault is marked on the three-dimensional building indoor distributed site distribution model according to the distribution information. By adopting the method provided in the embodiment of the present application, after generating a three-dimensional building indoor distributed site distribution model based on the acquired building indoor distributed system site data and building data, the floors of the three-dimensional building indoor distributed site distribution model are partitioned according to the indoor distributed antenna position, and the floor and area corresponding to the terminal in the three-dimensional building indoor distributed site distribution model are determined according to the height data and longitude and latitude data reported by the terminal. If the indoor distributed equipment in a certain partition fails, the terminal MR data collected in the partition will also be abnormal, and then the accurate fault identification of the building indoor distributed system can be achieved by monitoring the partitioned MR data. After the fault is identified, the fault position can be accurately located according to the corresponding distribution information of the MR data in the three-dimensional building indoor distributed site distribution model, which greatly improves the accuracy of fault detection and fault handling efficiency of the indoor distributed system.

[0091] In one implementation, the present application also provides a room-distributed system fault detection device to solve the problem that the existing room-distributed system fault detection method cannot accurately locate the fault area and has low fault location efficiency due to the single room-distributed fault acquisition channel. Figure 3 As shown, it includes: a modeling unit 31, a terminal positioning unit 32, a fault identification unit 33 and a labeling unit 34.

[0092] The modeling unit 31 is used to generate a three-dimensional building indoor distributed site distribution model according to the acquired building indoor distributed system site data and building data, wherein the building indoor distributed system site data includes indoor distributed equipment installation location data and network engineering parameter information, and the building data includes building location data and building size data;
