[0002] During the train operation, there are tunnel lines and ground lines. The wireless coverage methods for different lines are different. The tunnel lines are provided by the wireless backhaul vehicle-ground communication system, and the ground lines are provided by the ground operator network.

[0063] To make the objectives, technical solutions, and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Apparently, the described embodiments are some, rather than all, of the embodiments of the present application. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present application without creative efforts shall fall within the protection scope of the present application.

[0064] The following disclosure provides many different embodiments or examples for implementing different structures of the present invention. To simplify the disclosure of the present invention, the components and settings of specific examples are described below. Of course, they are only examples and are not intended to limit the present invention. In addition, the present invention may repeat reference numerals and / or letters in different examples. Such repetition is for the purpose of simplification and clarity and does not in itself indicate the relationship between the various embodiments and / or settings discussed.

[0065] To facilitate the understanding of the wireless backhaul train-ground system operation and maintenance method shown in the embodiments of the present application, the application scenarios related to the embodiments of the present application are first described below by way of example:

[0066] See Figure 1 , which is a schematic diagram of an application scenario of the wireless backhaul train-ground system operation and maintenance method. As Figure 1 shown, there are tunnel lines and ground lines during the operation of the train. Among them, the ground lines are covered by the operator's large network, and the tunnel lines are covered by the train-ground system ToB private network. During the operation of the train, due to the change of the vehicle position, the train will switch between different lines (i.e., tunnel lines and ground lines), so that the network used by the vehicle switches between different coverage methods.

[0067] The wireless backhaul vehicle-ground system includes multiple communication devices, specifically including: tunnel backhaul base stations, vehicle-mounted communication devices (routers, base stations, CPE (Customer Premise Equipment)), and ground communication devices (transmission devices, core network). Among them, the corresponding relationship between the vehicle-mounted communication devices and the vehicle identifiers is preset, and based on this, the vehicle-mounted communication devices can be managed according to the vehicle identifiers. In the application, the communication devices in the wireless backhaul vehicle-ground system can be uniformly managed through a ToB (to Business) network management system.

[0068] The network management system pre-marks multiple sentry base stations in the tunnel backhaul base station with the help of the intelligent operation and maintenance module, and the sentry base stations form a sentry base station group; based on the wireless transmission method, it can receive the messages uploaded by the sentry base station group, judge the train running position, and, based on the sentry base station group and the information uploaded by the sentry base station group, flexibly determine the operation and maintenance strategy for the target vehicle, thereby realizing the intelligent operation and maintenance of the vehicle-ground system.

[0069] Figure 2 It is a schematic flow chart of a method for operating and maintaining a wireless backhaul vehicle-ground system provided by an embodiment of the present application. As Figure 2 shown, the method specifically includes the following steps:

[0070] S201, determine the target vehicle identifier based on the received user equipment identifier and the identifier mapping list.

[0071] The execution subject of this solution is the vehicle-ground system, which receives the user equipment identifier from the sentry base station group. The user equipment identifier can be an identifier with a unique identification function, and can be the identifier of the CPE on the target vehicle. The CPE on each train in the vehicle-ground system is bound to a corresponding IP address in the core network. Therefore, the CPE IP can be used as the CPE identifier. In the application, the serial number (SN) can also be used as the CPE identifier.

[0072] Specifically, the identifier mapping list can be a list containing the corresponding relationship between the user equipment identifier and the vehicle identifier. Among them, the user equipment identifier and the vehicle identifier have a one-to-one correspondence. It is determined that the user equipment identifier can be mapped to the uniquely corresponding vehicle identifier through the identifier mapping list, where the user equipment identifier can be the CPE identifier.

[0073] In the embodiments of the present application, the user equipment identifier can be obtained through the sentry base station group. During the obtaining process, each sentry base station in the sentry base station group can perform real-time detection to check whether there is a vehicle-mounted CPE accessing the base station in the sentry base station group. When the target vehicle enters the detection range of any sentry base station, the sentry base station can detect the access of the vehicle-mounted CPE, and obtain the information uniquely identifying the CPE by parsing the access message of the CPE. Furthermore, the CPE identifier is reported to the network management system, and the network management system determines the corresponding target vehicle identifier according to the identifier mapping list.

[0074] In practical applications, when the target vehicle is within the detection range of a certain sentry base station, there is a situation where the sentry base station repeatedly uploads the CPE identifier of the target vehicle to the network management system. Therefore, in another embodiment of the present application, the method may further include the following steps:

[0075] For each sentry base station in the sentry base station group, when receiving the message containing the user equipment identifier uploaded by the sentry base station for the first time within a preset time period, perform the step of determining the target vehicle identifier based on the received user equipment identifier and the identifier mapping list. When receiving the message containing the user equipment identifier uploaded by the sentry base station not for the first time within a preset time period, mark the message as an invalid message.

[0076] In this embodiment, each time the network management system receives the CPE identifier uploaded by the sentry base station, first, it determines whether the sentry base station has uploaded a message within a preset duration (such as one minute). If not, it is the first time to receive the message uploaded by the sentry base station, and S201 is executed; if it has uploaded, it is not the first time to receive the message uploaded by the sentry base station, and the message is marked as an invalid message to ignore the message and reduce duplicate calculations.

[0077] S202, determine the operation and maintenance strategy corresponding to the target vehicle based on the target vehicle identifier and the sentry base station group.

[0078] In applications, for the operation and maintenance processing of the target vehicle, it is essentially the operation and maintenance processing of the vehicle-mounted communication device corresponding to the target vehicle. The above operation and maintenance strategy essentially refers to the maintenance processing strategy for the vehicle-mounted communication device corresponding to the target vehicle, and is used to instruct the vehicle-ground system to perform maintenance processing on the corresponding vehicle-mounted communication device.

[0079] In the embodiments of the present application, the environmental characteristics corresponding to the target vehicle can be determined according to the target base station that uploads the user equipment message in the sentry base station group, where the environmental characteristics are such as the location of the vehicle, the area where the vehicle is located, etc. The corresponding relationship between the vehicle identifier and the vehicle-mounted communication device is pre-configured in the network management system. For example, if the vehicle-mounted communication devices corresponding to vehicle a include a vehicle-mounted base station and a vehicle-mounted router, it means that a vehicle-mounted base station and a vehicle-mounted router are set on vehicle a.

[0080] Based on this, in the embodiments of the present application, the operation and maintenance strategy for each vehicle-mounted communication device on the target vehicle can be determined according to the environmental characteristics determined based on the sentry base station group and the vehicle-mounted communication device determined based on the target vehicle identifier.

[0081] As for how to determine the operation and maintenance strategy corresponding to the target vehicle based on the target vehicle identifier and the sentry base station group, it will be explained in detail through the following embodiments and will not be elaborated here for the time being.

[0082] S203, perform operation and maintenance processing on the target vehicle through the operation and maintenance strategy corresponding to the target vehicle.

[0083] In the embodiments of the present application, the environmental characteristics include two situations: entering a tunnel (i.e., inside the tunnel) and exiting a tunnel (i.e., outside the tunnel).

[0084] As an implementable manner of the embodiments of the present application, performing operation and maintenance processing on the target vehicle through the operation and maintenance strategy corresponding to the target vehicle may specifically include the following steps:

[0085] In the case where the environmental characteristic corresponding to the target vehicle is inside the tunnel, trigger a disenable instruction for the operation and maintenance strategy corresponding to the target vehicle to perform corresponding operation and maintenance processing on the target vehicle. In the case where the environmental characteristic corresponding to the target vehicle is outside the tunnel, trigger an enable instruction for the operation and maintenance strategy corresponding to the target vehicle to perform corresponding operation and maintenance processing on the target vehicle.

[0086] In applications, vehicles generally include vehicle-mounted communication devices such as vehicle-mounted base stations and vehicle-mounted routers. For each vehicle-mounted communication device on the target vehicle, the following strategies are executed according to whether the target vehicle is inside or outside the tunnel:

[0087] (1) The network management system enables the strategy for the vehicle-mounted communication device exiting the tunnel (i.e., outside the tunnel), generates a series of network element operation and maintenance instructions according to the intelligent strategy, and issues them to the network element to take effect.

[0088] ① Vehicle-mounted base station energy-saving strategy: The network management system generates an instruction list such as blocking or shutting down a cell, and issues it to the vehicle-mounted base station to take effect.

[0089] ② Vehicle-mounted router energy-saving strategy: The network management system generates an instruction list such as setting the sleep state or reducing the router power, and issues it to the vehicle-mounted router to take effect.

[0090] ③ User mobile device handover strategy: The network management system generates an instruction list such as blocking a cell, reducing power, or setting handover parameters, and issues it to the vehicle-mounted base station to take effect.

[0091] ④ Alarm suppression strategy: The network management system finds the ground communication network elements through the docking relationship between in-vehicle communication devices and ground communication devices (for example: the base station and the core network are connected through the NG interface, and the router and the transmission device are connected through the L2TP tunnel). The network management system matches according to the event of the train exiting the tunnel in the "event-alarm association model" of in-vehicle and ground communication network elements, generates a series of network element alarm suppression rules, and issues the rules to the in-vehicle and ground communication network elements to take effect within the specified time.

[0092] (2) For the in-vehicle communication devices entering the tunnel (i.e., inside the tunnel), the network management system disables the executed policies.

[0093] ① Disable the in-vehicle base station energy-saving strategy: The network management system generates a list of commands such as unlocking or activating the cell, and issues it to the in-vehicle base station to take effect.

[0094] ② Disable the in-vehicle router energy-saving strategy: The network management system generates a list of commands such as setting the activation status or restoring the router power, and issues it to the in-vehicle router to take effect.

[0095] ③ Disable the user mobile device handover strategy: The network management system generates a list of commands such as unlocking the cell, restoring the SSB power, or restoring the handover parameters, and issues it to the in-vehicle base station to take effect.

[0096] ④ Disable the alarm suppression strategy: The network management system issues an instruction to cancel the network element alarm suppression rule to the in-vehicle and ground communication network elements to take effect.

[0097] Through this solution, it can be avoided that when the vehicle is driving on a non-tunnel line, the in-vehicle communication device does not provide wireless network coverage, and the devices (such as in-vehicle base stations and in-vehicle routers) are still in the active state and consume energy; moreover, generally, there will be a double coverage section between the large network at the tunnel entrance and the vehicle-ground system network. Through this solution, the user mobile device can achieve fast and smooth handover between the two networks; finally, when the vehicle exits the tunnel line, the wireless backhaul link between the in-vehicle communication device and the tunnel backhaul base station is interrupted, and a series of invalid alarms will be generated by the communication devices of the vehicle-ground system, interfering with the normal network operation and maintenance. Through this solution, the invalid alarms can be reduced and the interference to network operation and maintenance can be avoided.

[0098] In the embodiments of the present application, first, the target vehicle identifier is determined based on the received user equipment identifier and the identifier mapping list. Then, the operation and maintenance policy corresponding to the target vehicle is determined based on the target vehicle identifier and the sentry base station group. Finally, the target vehicle is subjected to operation and maintenance processing through the operation and maintenance policy corresponding to the target vehicle. Through the present application, based on the sentry base station group included in the vehicle-ground system and the information uploaded by the sentry base station group, the operation and maintenance policy for the target vehicle can be flexibly determined, thereby realizing the intelligent operation and maintenance of the vehicle-ground system. Moreover, the software and hardware of the vehicle-ground system itself are relied on during the process of determining the operation and maintenance policy, without the need to additionally add software and hardware and third-party systems, thus reducing the deployment cost.

[0099] See Figure 3 , which is a flowchart of an embodiment of another method for operating and maintaining a wireless backhaul vehicle-ground system provided by the embodiments of the present application. The Figure 3 shown process is based on the process shown above Figure 1 to describe how to determine the operation and maintenance policy corresponding to the target vehicle based on the target vehicle identifier and the sentry base station group. As Figure 3 shown, the process may include the following steps:

[0100] S301, determine the sentry base station that uploads the user equipment identifier in the sentry base station group as the target base station.

[0101] In the application, the network management system supports the configuration of sentry base stations. The relevant parameters of the sentry base stations are added to the network element model of the tunnel backhaul base station, and the network management system issues these parameters to the corresponding base stations to take effect. The base station configured as a sentry (i.e., the sentry base station) turns on the CPE monitoring function. For a one-way traffic tunnel, according to the vehicle driving direction, a single base station at each tunnel entrance is set as the exit or entrance sentry base station; for a two-way traffic tunnel, at least 2 base stations near each tunnel entrance are set as a group as sentry base stations, and the front and back order of this group of sentry base stations is also set.

[0102] Based on this, each sentry base station can monitor the access of in-vehicle CPEs in real time. Once an in-vehicle CPE accesses, the CPE access message is parsed to obtain the information of the unique identifier CPE (i.e., the user equipment identifier), and it is reported to the network management system.

[0103] In the embodiments of the present application, the sentry base station that currently uploads the user equipment identifier is determined as the target base station to determine the environmental characteristics corresponding to the target vehicle through the target base station.

[0104] S302, determine the environmental characteristics corresponding to the target vehicle based on the target base station.

[0105] The environmental characteristics refer to the characteristics of the environment where the target vehicle is located, such as the location, area, etc.

[0106] In the embodiments of the present application, determining the environmental characteristics corresponding to the target vehicle based on the target base station may specifically include the following steps:

[0107] Obtain the configuration parameters corresponding to the target base station, where the configuration parameters include type information. Determine the base station type of the target base station based on the type information, and determine the environmental characteristics corresponding to the target vehicle based on the base station type.

[0108] The above type information is used to describe the type of the corresponding base station, and the type includes a one-way tunnel base station set in a one-way tunnel and a two-way tunnel base station set in a two-way tunnel.

[0109] As a possible implementation manner, the configuration parameters further include location information, the base station type includes a one-way tunnel base station, and the implementation of determining the environmental characteristics corresponding to the target vehicle based on the base station type may include the following steps:

[0110] Determine the position of the target base station relative to the one-way tunnel based on the location information. When the position is at the entrance of the one-way tunnel, determine that the environmental characteristic corresponding to the target vehicle is inside the tunnel. When the position is at the exit of the one-way tunnel, determine that the environmental characteristic corresponding to the target vehicle is outside the tunnel.

[0111] The above location information is used to represent the position of the corresponding base station in the tunnel, and the position generally includes the entrance of the tunnel and the exit of the tunnel.

[0112] In this embodiment, as Figure 4 shown, for each one-way tunnel base station, the network management system has pre-set the position relationship of the one-way tunnel base station relative to the tunnel, that is, Single-In (one-way tunnel entrance sentry base station) located at the entrance of the tunnel and Single-Out (tunnel exit sentry base station) located at the exit of the tunnel. Based on this, when receiving the CPE identifier uploaded by the one-way tunnel entrance sentry base station, it can be determined that the corresponding target vehicle is inside the tunnel. When receiving the CPE identifier uploaded by the one-way tunnel exit sentry base station, it can be determined that the corresponding target vehicle is outside the tunnel.

[0113] As another possible implementation manner, the configuration parameters further include distance information, the base station type includes a two-way tunnel base station, and the number of the target base stations is at least two. The implementation of determining the environmental characteristics corresponding to the target vehicle based on the base station type may include the following steps:

[0114] Determine the nearest distance between each of the target base stations and the tunnel entrance based on the distance information, sort all the target base stations in ascending order of the corresponding nearest distances to obtain a base station sorting result, obtain the upload order in which each of the target base stations uploads the user equipment identifier, and when the upload order is consistent with the sorting result, determine that the environmental feature corresponding to the target vehicle is inside the tunnel, and when the upload order is opposite to the sorting result, determine that the environmental feature corresponding to the target vehicle is outside the tunnel.

[0115] The above distance information is used to represent the nearest distance of the corresponding base station relative to the tunnel entrance. For example, if the distance between base station 1 and tunnel entrance a is 1m and the distance between base station 1 and tunnel entrance b is 10m, then 1m is the distance information corresponding to base station 1.

[0116] In this embodiment, for the two-way tunnel base stations, the network management system has pre-set the distance relationship between each two-way tunnel base station and the tunnel. Taking the number of target base stations as two as an example, the base station closer to the tunnel entrance is the pre-order sentry base station, and the base station farther from the tunnel entrance is the post-order sentry base station.

[0117] Based on this, for the same target vehicle, if the CPE identifier corresponding to the target vehicle uploaded by the pre-order sentry base station is received first and then the CPE identifier uploaded by the post-order sentry base station is received, it is determined that the target vehicle has entered the tunnel (i.e., is inside the tunnel); if the CPE identifier corresponding to the target vehicle uploaded by the post-order sentry base station is received first and then the CPE identifier uploaded by the pre-order sentry base station is received, it is determined that the target vehicle has exited the tunnel (i.e., is outside the tunnel).

[0118] S303. Determine the operation and maintenance strategy corresponding to the target vehicle based on the environmental feature and the target vehicle identifier.

[0119] In the embodiment of the present application, determining the operation and maintenance strategy corresponding to the target vehicle based on the environmental feature and the target vehicle identifier may specifically include the following steps:

[0120] Obtain an operation and maintenance strategy set, where the operation and maintenance strategy set includes at least two sub-strategy sets. According to the preset corresponding relationship between the environmental feature and the strategy set, determine the sub-strategy set corresponding to the environmental feature as the target strategy set, and determine the operation and maintenance strategy corresponding to the target vehicle from the target strategy set based on the target vehicle identifier.

[0121] In the application, the operation and maintenance strategy set generally includes a sub-strategy set corresponding to inside the tunnel and a sub-strategy set corresponding to outside the tunnel. Based on this, the corresponding sub-strategy set can be determined in the operation and maintenance strategy set according to the environmental feature, and the final operation and maintenance strategy can be determined in the sub-strategy set to reduce the calculation amount.

[0122] As an implementable manner of the embodiment of the present application, determining the target operation and maintenance policy from the target policy set based on the target vehicle identifier may include the following steps:

[0123] Determine at least one in-vehicle communication device corresponding to the target vehicle based on the target vehicle identifier. For each in-vehicle communication device, determine the operation and maintenance policy corresponding to the in-vehicle communication device in the target policy set as the operation and maintenance policy corresponding to the target vehicle according to the preset corresponding relationship between the communication device and the operation and maintenance policy.

[0124] In the application, the corresponding relationship between each vehicle identifier and the in-vehicle communication device is preset in the network management system. Based on this corresponding relationship, it can be determined which in-vehicle communication devices are included in the target vehicle. Furthermore, the corresponding operation and maintenance policies are determined for the in-vehicle communication devices included in the target vehicle.

[0125] For example, the target policy set includes Policy 1 corresponding to in-vehicle communication device a, Policy 2 corresponding to in-vehicle communication device b, and Policy 3 corresponding to in-vehicle communication device c. If the in-vehicle communication devices corresponding to the target vehicle are in-vehicle communication device a and b, then determine Policy 1 and Policy 2 as the operation and maintenance policies corresponding to the target vehicle. Thus, the intelligent determination of the operation and maintenance policy is realized.

[0126] Through Figure 3 the shown process, based on the environmental characteristics corresponding to the target vehicle determined by the sentry base station group and the target vehicle identifier, the intelligent determination of the operation and maintenance policy can be realized without manual operation, improving the efficiency and accuracy of policy determination.

Then, an operation and maintenance policy corresponding to the target vehicle is determined based on the target vehicle identifier and the sentry base station group. Finally, the target vehicle is subjected to operation and maintenance processing through the operation and maintenance policy corresponding to the target vehicle. Through the present application, based on the sentry base station group included in the vehicle-ground system and the information uploaded by the sentry base station group, the operation and maintenance policy for the target vehicle can be flexibly determined, thereby realizing the intelligent operation and maintenance of the vehicle-ground system. Moreover, the software and hardware of the vehicle-ground system itself are relied on during the process of determining the operation and maintenance policy, without the need to additionally add software and hardware and third-party systems, thus reducing the deployment cost.
