[0021] To help those skilled in the art better understand the technical solutions of the embodiments of the present disclosure, the technical solutions of the present disclosure will be clearly and completely described below in conjunction with the drawings in the present disclosure. Obviously, the embodiments described are only part of the embodiments of the present disclosure, not all of them. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present disclosure without making any creative efforts shall fall within the scope of protection of the present disclosure.

[0022] It should be noted that in this disclosure, words such as "exemplary" or "for example" are used to indicate examples, illustrations, or descriptions. Any embodiment or design described in this disclosure as "exemplary" or "for example" should not be construed as being preferred or advantageous over other embodiments or designs. Rather, the use of words such as "exemplary" or "for example" is intended to present the relevant concepts in a concrete manner.

[0023] In the following, the terms "first," "second," etc. are used for descriptive purposes only and should not be understood to indicate or imply relative importance or implicitly specify the quantity of the technical features indicated. Therefore, a feature specified as "first," "second," etc. may explicitly or implicitly include one or more of the features.

"And / or" in this document simply describes an association relationship between related objects, indicating that three relationships can exist. For example, "A and / or B" can mean: only A, A and B, or only B. Furthermore, "at least one" means one or more, and "a plurality" means two or more.

[0025] With the continuous advancement of communications technology, wireless network technology has been widely applied in various fields. During the use of wireless networks, operation and maintenance are often required to ensure their normal operation. Since wireless network failures are often related to the air interface environment, which is often related to the location of terminal devices within the service network, during wireless network operation and maintenance, operators need to determine the specific location of the network failure in order to troubleshoot it.

[0026] In related technologies, wireless network operations and maintenance are typically performed at the cell level, specifically to ensure overall network performance and availability. Consequently, when a wireless network failure occurs, operations and maintenance personnel are unable to quickly locate the fault within the service network and are forced to rely on manual drive testing, resulting in low operational efficiency.

[0027] In light of this, embodiments of the present disclosure provide a network operation and maintenance method that monitors network anomalies on terminal devices and, based on the terminal device's fault information, rapidly locates the fault location within the terminal device's service network. Compared to related techniques where operators manually determine the fault location through drive testing, the network operation and maintenance method provided by embodiments of the present disclosure rapidly locates the fault, thereby improving network operation and maintenance efficiency.

[0028] The present disclosure provides a network operation and maintenance system for executing the network operation and maintenance method provided in the present disclosure. Referring to Figure 1 , Figure 1 illustrates an application scenario of a network operation and maintenance system according to an embodiment of the present disclosure. The network operation and maintenance system includes a network operation and maintenance apparatus 100 and multiple terminal devices 110. Multiple terminal devices 110 are located within a service network and communicate with other terminal devices via the network provided by the service network.

[0029] It should be understood that multiple terminal devices may be located in the same cell or in different cells, and the embodiments of the present disclosure do not impose any particular limitation on this.

[0030] In one possible implementation, the target network may be a 4G (LTE) network or a 5G (NR) network.

[0031] It should be understood that the terminal device 110 can be set up indoors or outdoors, and the embodiments of the present disclosure do not impose any particular restrictions on the setting scenario of the terminal device.

[0032] In some embodiments, a wireless communication connection may be established between the network operation and maintenance apparatus 100 and the terminal device 110. For example, the wireless communication connection may include a short-range wireless communication connection such as a Bluetooth communication connection, a near-field communication connection, and a wireless local area network communication connection.

[0033] In some embodiments, the wireless communication technology for establishing a wireless communication connection includes but is not limited to at least one of the following: wireless local area networks (WLAN) (such as wireless fidelity (Wi-Fi) networks), Bluetooth (BT) (for example, traditional Bluetooth or Bluetooth low energy (BLE)), near field communication (NFC), Zigbee, frequency modulation (FM), and infrared (IR), etc.

[0034] It is understood that the network operation and maintenance apparatus 100 shown in the embodiments of the present disclosure may be any computing device with computing processing capabilities, or a functional module within such a computing device. For example, the network operation and maintenance apparatus 100 may be a general-purpose computer, a personal computer, a server, a router, a switch, a base station, etc. The embodiments of the present disclosure do not limit the implementation of the network operation and maintenance apparatus 100.

[0035] In some embodiments, the terminal device 110 in the embodiments of the present disclosure may be, for example, a mobile phone, a tablet computer, a personal computer (PC), a personal digital assistant (PDA), a smart watch, a netbook, a wearable device, an augmented reality (AR) device, a virtual reality (VR) device, a vehicle-mounted device, a smart screen, a smart car, a smart speaker, a robot, etc. The present disclosure does not impose any special restrictions on the form of the terminal device 110.

[0036] The following embodiments are illustratively described using an example in which the network operation and maintenance apparatus 100 is a computing device and the terminal device 110 is a mobile phone.

[0037] Figure 2 is an interactive flow chart of a network operation and maintenance method according to an embodiment of the present disclosure. As shown in Figure 2, the network operation and maintenance method can be executed by the network operation and maintenance device 100 shown in Figure 1. The network operation and maintenance method can include the following S201 to S203.

[0038] In S201, when a network abnormality event of a terminal device is detected, fault information of the terminal device is obtained, where the fault information of the terminal device includes the location of the terminal device.

[0039] For example, a network anomaly event can be understood as an event in which a terminal device experiences a network failure. A network failure can include any type of failure or anomaly related to the terminal device and the network that can be detected by the network operation and maintenance device. For example, a network failure can include a terminal device failing to switch cells, an abnormal disconnection of a terminal device, or any network metric of a terminal device falling below a preset threshold. The embodiments of this disclosure do not specifically limit the manner in which a network anomaly event occurs.

[0040] The fault information of the terminal device may be the fault information reported by the terminal device to the network operation and maintenance device when a network abnormality occurs, or it may be the fault information actively obtained by the network operation and maintenance device when a network abnormality occurs in the terminal device. The embodiment of the present disclosure does not impose any special restrictions on the implementation method of the network operation and maintenance device obtaining the fault information of the terminal device.

[0041] In one possible implementation, the location of the terminal device is acquired in real time by the network operation and maintenance apparatus using high-precision cellular network wireless positioning technology. In other words, when the network operation and maintenance apparatus detects a network anomaly with the terminal device, the terminal device's location is acquired in real time using high-precision cellular network wireless positioning technology.

[0042] In some embodiments, high-precision cellular network wireless positioning technology includes an uplink time difference of arrival (UTDOA) positioning algorithm, a round trip time (RTT) positioning algorithm, or an angle of arrival (AOA) positioning algorithm to achieve position determination function.

[0043] In one example, a network operation and maintenance device determines the location of a terminal device based on the UTDOA positioning algorithm. First, the network operation and maintenance device measures the arrival time of a sounding reference signal (SRS) sent by the terminal device using multiple base station wireless signal transceivers located around the terminal device. The device then determines the terminal device's location based on the arrival time differences of the multiple SRSs.

[0044] In another example, a network operation and maintenance device determines the location of a terminal device based on an RTT positioning algorithm and an AOA positioning algorithm. First, the network operation and maintenance device determines the time it takes for a signal from the terminal device to reach a base station (or vice versa). Then, the device determines the distance between the terminal device and the base station based on the signal propagation speed. Finally, the device determines the location of the terminal device based on the angle of incidence of the terminal signal transmitted to the base station.

[0045] In S202, a target sub-area is determined from a service network of the terminal device according to the location of the terminal device.

[0046] For example, the service network of the terminal device is pre-divided into multiple sub-areas, and the target sub-area is one of the multiple sub-areas.

[0047] In one possible implementation, the service network is pre-divided into multiple grid units based on a preset coordinate system, each grid unit corresponds to a sub-area of ​​multiple sub-areas included in the service network of the terminal device, and the grid unit is configured with corresponding coordinates in the preset coordinate system.

[0048] 3 , the above-mentioned S202 , for example, includes the following S2021 to S2023 .

[0049] In S2021, the coordinates of the terminal device in a preset coordinate system are determined according to the position of the terminal device.

[0050] For example, the location of the terminal device may be the geographical location information of the terminal device or the coordinates of the terminal device in another coordinate system. Assume that the location of the terminal device is the coordinates of the terminal device in the first coordinate system. The network operation and maintenance device converts the coordinates of the terminal device according to the preset coordinate system and the first coordinate system to obtain the coordinates of the terminal device in the preset coordinate system.

[0051] In S2022, the grid unit where the terminal device is located is determined based on the coordinates.

[0052] For example, the coordinates of the terminal device in the preset coordinate system correspond to a coordinate point in the preset coordinate system, and the unit grid where the coordinate point is located is determined as the grid unit where the terminal device is located.

[0053] In S2023, the sub-area corresponding to the grid unit where the terminal device is located is determined as the target sub-area.

[0054] From the above, it can be seen that the network operation and maintenance method provided by the embodiment of the present disclosure divides the service network into multiple unit grids, and then determines the sub-area corresponding to the grid unit where the terminal device is located as the target sub-area, so that the area where the fault occurs in the service network can be quickly determined.

[0055] In S203, regional fault information of the target sub-region and fault maintenance information corresponding to the regional fault information are determined.

[0056] The regional fault information is information identifying a fault in a target sub-region, and the fault maintenance information includes the fault cause and fault repair method of the target sub-region where the fault occurs.

[0057] In a possible implementation, referring to FIG. 4 , the above S203 , for example, includes the following S2031 to S2033 .

[0058] In S2031 , the number of abnormal network events in the target sub-area is determined.

[0059] For example, the number of network anomaly events is the number of network failures that occurred in terminal devices within the target sub-area. It should be understood that the number of network anomaly events is the sum of the number of network failures that occurred in multiple terminal devices within the target sub-area, rather than the number of network failures that occurred in one terminal device among the multiple terminal devices within the target sub-area.

[0060] For example, the network operation and maintenance device monitors that the number of network failures occurring in terminal device A in the target sub-area is 4 times, and the number of network failures occurring in terminal device B is 5 times. Then the number of network abnormal events in the target sub-area is the sum of the number of network abnormal events of terminal device A and terminal device B, which is 9 times.

[0061] In some embodiments, the fault information of the terminal device further includes the occurrence time of the network abnormality event, the fault type, and the cell information.

[0062] For example, when the network operation and maintenance device detects a network anomaly event in a terminal device, it obtains the time when the network anomaly event occurred and determines the fault type of the network anomaly event. For example, when the network anomaly event is a failure of the terminal device to switch cells, the network operation and maintenance device determines the fault type as a failure of the terminal device to switch cells. When the network anomaly event is any network indicator of the terminal device being less than a preset threshold, the network operation and maintenance device determines the fault type as an abnormality of the network indicator of the terminal device.

[0063] It should be understood that the fault type of the terminal device can be set according to the user's actual network usage needs, and the embodiments of the present disclosure do not specifically limit the manner in which the fault type occurs.

[0064] In some embodiments, the above S2031 , for example, includes the following: determining, according to the fault information, the number of network abnormal events corresponding to each fault type in the target sub-area within a preset time period.

[0065] For example, the network operation and maintenance device determines the network abnormal events of the terminal devices in the target sub-area within a preset time period based on the occurrence time of the network abnormal events carried in the fault information of the terminal devices, and then determines the number of network abnormal events corresponding to each fault type in the target sub-area within the preset time period based on the fault type carried in the fault information of the terminal devices.

[0066] As can be seen from the above, on the one hand, the network operation and maintenance method provided by the embodiment of the present disclosure realizes a finer-grained division of the faults of the terminal device by dividing the network abnormal events of the terminal device into multiple fault types and determining the number of network abnormal events corresponding to each fault type, and the user can set different fault types according to their own usage needs, thereby meeting the user's usage needs in different usage scenarios. On the other hand, by determining the number of network abnormal events within a preset time period based on the occurrence time of the network abnormal event, rather than determining the number of network abnormal events based on all network abnormal events that have occurred in the target sub-area, the fault corresponding to the network abnormal event that occurred a long time ago may have been repaired by the operation and maintenance personnel. Therefore, determining whether the target sub-area is faulty based on the number of network abnormal events within the preset time period can improve the accuracy of fault detection.

[0067] In S2032 , regional fault information of the target sub-region is determined according to the number of network abnormal events and a first threshold.

[0068] For example, when the number of abnormal network events in the target sub-region is greater than a first threshold, regional fault information of the target sub-region is determined, that is, it is determined that a fault occurs in the target sub-region.

[0069] It should be understood that the first threshold can be set according to actual network usage requirements, and the embodiment of the present disclosure does not impose any particular limitation on the setting method of the first threshold.

[0070] In one possible implementation, the network operation and maintenance device may also pre-set multiple threshold intervals, each threshold interval corresponding to a different fault level, and determine the regional fault information and corresponding fault level of the target sub-area based on the threshold interval in which the number of network abnormal events in the target sub-area lies.

[0071] In S2033, fault maintenance information corresponding to the regional fault information is determined.

[0072] In some embodiments, referring to FIG. 5 , the above-mentioned S2033 , for example, includes the following S20331 and S20332 .

[0073] In S20331, network indicator information of the target sub-area is obtained.

[0074] The network indicator information is indicator information related to communication with terminal devices within the target sub-area. The network operation and maintenance device obtains the network indicator information of each terminal device from all terminal devices within the target sub-area, then determines an average value of each network indicator in the network indicator information of all terminal devices, and finally determines the average value of each network indicator in the network indicator information of all terminal devices within the target sub-area as the network indicator information of the target sub-area.

[0075] In some embodiments, the network indicator information includes channel information and uplink and downlink information of the terminal equipment in the target sub-area, the channel information includes at least one of the reference signal received power, the sounding reference signal, and the signal to interference plus noise ratio; the uplink and downlink information includes at least one of the uplink modulation and coding strategy, the downlink modulation and coding strategy, the uplink resource block, the downlink resource block, the number of uplink streams, the number of downlink streams, the number of uplink scheduling times, the number of downlink scheduling times, the physical uplink shared channel signal strength, the physical uplink shared channel signal to interference plus noise ratio, and the physical uplink shared channel noise floor.

[0076] It should be understood that the network indicator information provided in the embodiment of the present disclosure is only for illustrative purposes. The network indicator information of the target sub-area may also include other indicator information, and the embodiment of the present disclosure does not impose any particular limitation on the content of the network indicator information.

[0077] In S20332, fault maintenance information corresponding to the regional fault information is determined based on the network indicator information of the target sub-region.

[0078] For example, the network operation and maintenance device determines the fault maintenance information corresponding to the regional fault information based on the network indicator information of the target sub-region and a preset algorithm.

[0079] In one possible implementation, the preset algorithm may be a pre-trained neural network model, and the network operation and maintenance device inputs the network indicator information of the target sub-area into the neural network model to obtain fault maintenance information output by the neural network model.

[0080] In another possible implementation, the preset algorithm may be a pre-established database, which includes fault maintenance information corresponding to values ​​of different network indicator information or combinations of values ​​of different network indicator information. The network operation and maintenance device obtains the fault maintenance information corresponding to the network indicator information of the target sub-area from the database based on the network indicator information of the target sub-area.

[0081] It should be understood that the network operation and maintenance device may also determine the fault maintenance information based on the network indicator information of the target sub-area in other ways, and the embodiment of the present disclosure does not impose any particular limitation on the method for determining the fault maintenance information.

[0082] In one possible implementation, when the network operation and maintenance device determines that multiple adjacent sub-areas included in the service network have faults, the multiple adjacent sub-areas can be merged to obtain a target sub-area, and then the fault maintenance information corresponding to the multiple adjacent sub-areas can be determined based on the network indicator information of the target sub-area.

[0083] In this way, the network operation and maintenance device merges multiple adjacent sub-areas where faults occur, and then determines the fault maintenance information corresponding to the merged area, so that the operation and maintenance personnel can eliminate the faults of multiple adjacent sub-areas at one time according to the fault maintenance information, which can effectively improve the operation and maintenance efficiency.

[0084] As can be seen from S201 to S203 above, the network operation and maintenance method provided in the embodiments of the present disclosure monitors network anomalies of terminal devices and, based on the fault information of the terminal devices, can quickly determine the fault location within the terminal device's service network. Compared to the related art where operation and maintenance personnel manually determine the fault location through drive testing, the network operation and maintenance method provided in the embodiments of the present disclosure can quickly determine the fault location, thereby improving network operation and maintenance efficiency.

[0085] In some embodiments, the network operation and maintenance method provided by the embodiments of the present disclosure further includes: displaying regional fault information and fault maintenance information of the target sub-area.

[0086] For example, the network operation and maintenance device can display multiple target sub-areas included in the service network, each target sub-area is configured with a corresponding control, and in response to the user selecting the control, the fault warning results and fault maintenance information of the target sub-area corresponding to the control are displayed.

[0087] It should be understood that target sub-areas of different fault types are marked with different colors. When the regional fault information of the target sub-area includes the fault level, each fault level corresponds to a different color. The network operation and maintenance device identifies a different color for each target sub-area based on the fault level of each target sub-area.

[0088] Through the above presentation, operation and maintenance personnel can intuitively view the regional fault information and fault maintenance information of each sub-area included in the service network, and then quickly troubleshoot the fault, thereby improving network operation and maintenance efficiency.

[0089] In the actual network operation and maintenance process, in related technologies, network failures are usually repaired when they occur, and early warning of network failures cannot be issued, resulting in a poor user experience.

[0090] To solve the above problem, in some embodiments, referring to FIG. 6 , the network operation and maintenance method provided by the embodiment of the present disclosure further includes S601 : determining an edge sub-area from multiple sub-areas included in the service network.

[0091] For example, the edge sub-area is an edge area of ​​the service network, that is, an edge of the service network coverage area.

[0092] In some embodiments, referring to FIG. 7 , the above S601 , for example, includes the following S6011 and S6012 .

[0093] In S6011 , edge grid cells are determined from a plurality of grid cells.

[0094] For example, the preset coordinate system used to divide the plurality of network units includes a plane rectangular coordinate system or a space rectangular coordinate system.

[0095] In some embodiments, when the preset coordinate system is a plane rectangular coordinate system, the first grid unit is determined to be an edge grid unit, the first grid unit is a grid unit for which network indicator information has been obtained, and the number of adjacent grid units of the first grid unit is less than 4, and the adjacent grid units of the first grid unit are grid units that share an edge with the first grid unit.

[0096] In other embodiments, when the preset coordinate system is a spatial rectangular coordinate system, the second grid unit is determined to be an edge grid unit, the second grid unit is a grid unit for which network indicator information has been obtained, and the number of adjacent grid units of the second grid unit is less than 6, and the adjacent grid units of the second grid unit are grid units that share a face with the second grid unit.

[0097] In S6012, the sub-region corresponding to the edge grid unit is determined as the edge sub-region.

[0098] As can be seen from S6011 and S6012, the network operation and maintenance method provided by the embodiment of the present disclosure can quickly determine the edge area of ​​the service network based on the grid units located at the edge through the pre-divided multiple grid units.

[0099] In S602, a fault warning result is determined based on the network indicator parameters of the terminal devices in the edge sub-area.

[0100] For example, the network operation and maintenance device makes a judgment based on the change trend of the network indicator parameters of the terminal device within multiple preset time periods and whether the network indicator parameters are less than a preset threshold value to obtain a fault warning result.

[0101] It should be understood that the network operation and maintenance device may first determine all edge sub-areas within the service network, and then determine the fault warning result for each edge sub-area based on the network indicator parameters of the terminal devices in each edge sub-area. The network operation and maintenance device may also determine the fault warning result for each edge sub-area determined, until the fault warning results for all edge sub-areas are determined. The embodiments of the present disclosure do not impose any particular restrictions on the order in which the network operation and maintenance device determines the fault warning results.

[0102] In some embodiments, when the network indicator parameters include reference signal received power and signal to interference plus noise ratio, referring to FIG. 8 , the above S602 , for example, includes the following S6021 and S6022 .

[0103] In S6021, when the reference signal received power of the edge sub-area is less than the second threshold, it is determined that the fault warning result is that the network signal coverage strength of the edge sub-area is low.

[0104] In S6022, when the reference signal received power of the edge sub-area is greater than the third threshold and the signal to interference plus noise ratio is less than the fourth threshold, it is determined that the fault warning result is that the signal interference intensity of the edge sub-area is high.

[0105] From the above, it can be seen that the embodiment of the present disclosure can provide early warning of faults within the service network by determining the edge area of ​​the service network and determining the fault warning results based on the network indicator parameters of the edge area, thereby achieving rapid repair of the faults and improving the user experience.

[0106] In a possible implementation, the network operation and maintenance method provided by the embodiment of the present disclosure further includes: determining fault maintenance information of the edge sub-area based on the fault warning result and network indicator parameters of the edge sub-area.

[0107] In some embodiments, the network operation and maintenance method provided by the embodiments of the present disclosure further includes: displaying the edge sub-area of ​​the service network and the fault warning results and fault maintenance information of the edge sub-area.

[0108] For example, the network operation and maintenance device can display multiple edge sub-areas of the service network, each of which is configured with a corresponding control. In response to the user selecting the control, the fault warning result and fault maintenance information of the edge sub-area are displayed.

[0109] Through the above presentation, operation and maintenance personnel can intuitively view the fault warning results and fault repair information of different edge sub-areas, and then quickly troubleshoot the faults, thereby improving network operation and maintenance efficiency.

[0110] Figure 9 is a structural diagram of a network operation and maintenance device according to an embodiment of the present disclosure, which can execute the network operation and maintenance method provided by the above-mentioned method embodiment. As shown in Figure 9, the network operation and maintenance device includes a monitoring unit 910 and a processing unit 920. The monitoring unit 910 is used to obtain the fault information of the terminal device when a network abnormality event of the terminal device is monitored. The fault information of the terminal device includes the location of the terminal device; the processing unit 920 is used to determine the target sub-area from the service network of the terminal device according to the location of the terminal device. The processing unit 920 is also used to determine the regional fault information of the target sub-area and the fault maintenance information corresponding to the regional fault information.

[0111] In some embodiments, the processing unit 920 is used, for example, to: determine the number of network abnormal events in the target sub-area; determine regional fault information of the target sub-area based on the number of network abnormal events and a first threshold; and determine fault maintenance information corresponding to the regional fault information.

[0112] In one possible implementation, the fault information of the terminal device also includes the occurrence time of the network abnormality event, the fault type, and the cell information.
