Description

Technical Field

[0001] This application relates to the field of communication technology, and in particular to an AP management method and apparatus. Background Technology

[0002] The metro depot is a crucial unit in the metro operating system, serving as the location for the operation, management, parking, maintenance, and repair of vehicles within urban rail transit systems (such as metro systems). The number of vehicles that can be parked depends on the size of the depot, typically around 50. In recent years, with the expansion of depots, the daily capacity has increased to over 80 vehicles. This has significantly increased the workload for maintaining the vehicle-to-ground wireless network. For example, when upgrading the version of the onboard APs operating in Fat Access Point (AP) mode, or changing the configuration information of the onboard APs, administrators usually need to manually perform the upgrades or configuration changes, resulting in substantial manpower costs. 。 Summary of the Invention

[0003] To overcome the problems existing in related technologies, this application provides an AP management method and apparatus.

[0004] According to a first aspect of the embodiments of this application, an AP management method is provided, the method being applied to an access controller (AC), the method comprising:

[0005] Upon receiving an association instruction from the administrator indicating permission for the vehicle-mounted AP to associate with the AC, the association instruction is sent to each trackside AP in the locally configured vehicle-mounted AP group that has a mesh connection. This allows each trackside AP to forward the association instruction to its corresponding vehicle-mounted AP, which then initiates the association process with the AC. Each vehicle-mounted AP operates in fat AP mode, while the trackside APs that have a mesh connection with each vehicle-mounted AP operate in thin AP mode.

[0006] For each vehicle-mounted AP, after the vehicle-mounted AP is associated with the AC through a trackside AP that has established a Mesh connection with the vehicle-mounted AP, if it is determined that the version number of the obtained version of the vehicle-mounted AP is inconsistent with the version number of the target version, the trackside AP sends the target version to the vehicle-mounted AP so that the vehicle-mounted AP can upgrade its version based on the target version.

[0007] After the onboard AP completes its version upgrade and reconnects to the AC via the trackside AP, if the configuration information corresponding to the onboard AP group is stored locally, the trackside AP will send the configuration information to the onboard AP so that the onboard AP can update its local configuration information based on the configuration information.

[0008] According to a second aspect of the embodiments of this application, an AP management device is provided, the device being applied to an AC, the device comprising:

[0009] The first management module is used to send the association instruction to each trackside AP that has established a Mesh connection with each vehicle AP in the locally configured vehicle AP group when it receives an association instruction input by the administrator to indicate that the vehicle AP is allowed to associate with the AC. This allows each trackside AP to forward the association instruction to the corresponding vehicle AP, and the corresponding vehicle AP to initiate the association process to the AC. The working mode of each vehicle AP is fat AP mode, and the working mode of the trackside AP that has established a Mesh connection with each vehicle AP is thin AP mode.

[0010] The second management module, for each vehicle-mounted AP, after the vehicle-mounted AP is associated with the AC through a trackside AP with which it has a mesh connection, if it determines that the version number of the obtained vehicle-mounted AP is inconsistent with the target version number, then it sends the target version to the vehicle-mounted AP through the trackside AP, so that the vehicle-mounted AP can upgrade based on the target version; and

[0011] After the onboard AP completes its version upgrade and reconnects to the AC via the trackside AP, if the configuration information corresponding to the onboard AP group is stored locally, the trackside AP will send the configuration information to the onboard AP so that the onboard AP can update its local configuration information based on the configuration information.

[0012] According to a third aspect of the present application, an electronic device is provided, including a processor and a machine-readable storage medium, the machine-readable storage medium storing machine-executable instructions executable by the processor, the processor being prompted by the machine-executable instructions to implement the method steps of the above-described AP management method.

[0013] According to a fourth aspect of the embodiments of this application, a computer-readable storage medium is provided, wherein a computer program is stored therein, and when the computer program is executed by a processor, it implements the method steps of the above-described AP management method.

[0014] The technical solutions provided by the embodiments of this application may include the following beneficial effects:

[0015] In this embodiment, the administrator no longer needs to manually manage the onboard APs operating in fat AP mode in the subway depot. Instead, the AC actively notifies the onboard APs operating in fat AP mode in the locally configured onboard AP group through the relevant trackside APs of the association instructions entered by the administrator. The onboard APs then associate with the AC through the relevant trackside APs, thereby enabling the AC to manage these onboard APs, which greatly saves manpower costs.

[0024] The embodiments of this application will now be described in detail.

[0025] This application provides an AP management method, which is applied to AC, such as... Figure 1 As shown, the method may include the following steps:

[0026] S11. Upon receiving the association instruction input by the administrator, which indicates that the vehicle-mounted AP is allowed to associate with the AC, the association instruction is sent to each trackside AP in the locally configured vehicle-mounted AP group that has a Mesh connection, so that each trackside AP forwards the association instruction to the corresponding vehicle-mounted AP, and the corresponding vehicle-mounted AP initiates the association process to the AC.

[0027] In this step, each vehicle-mounted AP operates in fat AP mode, while the trackside APs that have established a Mesh connection with each vehicle-mounted AP operate in thin AP mode.

[0028] S12. For each vehicle-mounted AP, after the vehicle-mounted AP is associated with the AC through the trackside AP that has established a Mesh connection with the vehicle-mounted AP, if it is determined that the version number of the obtained version of the vehicle-mounted AP is inconsistent with the version number of the target version, the target version is sent to the vehicle-mounted AP through the trackside AP so that the vehicle-mounted AP can upgrade the version based on the target version.

[0029] In this step, the target version can be the AC version or the new version that the vehicle APs in the vehicle AP group configured by the administrator on the AC need to be upgraded to.

[0030] S13. After the vehicle-mounted AP completes its version upgrade and reconnects to the AC via the trackside AP, if the configuration information corresponding to the vehicle-mounted AP group is stored locally, the configuration information is sent from the trackside AP to the vehicle-mounted AP so that the vehicle-mounted AP can update its local configuration information based on the configuration information.

[0031] It should be noted that in step S11 above, the vehicle-mounted AP group is pre-deployed on the AC by the administrator so that the AC can proactively notify the vehicle-mounted APs in the locally configured vehicle-mounted AP group whose working mode is fat AP, based on the association command entered by the administrator (which is usually entered by the administrator when they know that all the vehicle-mounted APs in the vehicle-mounted AP group have been parked in the designated depot). The vehicle-mounted APs then associate with the AC through the relevant trackside APs, thereby enabling the AC to manage these vehicle-mounted APs and greatly saving manpower costs.

[0032] Specifically, in step S12 above, the AC can obtain the version number of the vehicle-mounted AP in the following way:

[0033] After the vehicle-mounted AP is associated with the AC through the trackside AP that has established a Mesh connection with the vehicle-mounted AP, the trackside AP sends a query request to the vehicle-mounted AP to query the version number of the vehicle-mounted AP.

[0034] Receive the query response sent by the vehicle-mounted AP through the trackside AP, which carries the version number of the vehicle-mounted AP, and obtain the version number of the vehicle-mounted AP from the query response.

[0035] It should be noted that, in this embodiment of the application, for any vehicle-mounted AP in the vehicle-mounted AP group, after receiving the above-mentioned association instruction, it will initiate an association process to the AC through the trackside AP that has established a Mesh connection with the vehicle-mounted AP. The specific association process is existing technology and will not be described in detail here.

[0036] Once the vehicle-mounted AP is associated with the AC, it means that the vehicle-mounted AP has established a Controlling and Provisioning of Wireless Access Point (CAPWAP) tunnel with the AC through the trackside AP with which it has established a Mesh connection, so that the AC can subsequently manage the vehicle-mounted AP through the CAPWAP tunnel.

[0037] In addition, in step S12 above, when the AC performs the operation of sending the target version to the vehicle-mounted AP through the trackside AP, the specific implementation process is as follows: the AC sends the target version to the vehicle-mounted AP through the CAPWAP tunnel established between the trackside AP and the AC.

[0038] Specifically, in step S13 above, when the AC performs the operation of sending configuration information to the vehicle-mounted AP through the trackside AP, the specific implementation process is as follows: the AC sends configuration information to the vehicle-mounted AP through the CAPWAP tunnel established between the trackside AP and the AC.

[0039] For example, suppose there are n onboard APs operating in fat AP mode at a certain subway depot, such as onboard AP1, onboard AP2, ..., and onboard APn. The administrator has previously configured onboard AP group 1 on the AC, which includes onboard AP1, onboard AP2, ..., and onboard APn.

[0040] Suppose that at a certain moment, these onboard APs are parked in the subway depot. The administrator enters association command 1 on the AC, indicating that the onboard APs are allowed to associate with the AC. At this time, the AC will issue association command 1 to the trackside APs that have established a mesh connection with each onboard AP in onboard AP group 1. Here, the trackside APs that have established a mesh connection with each onboard AP in onboard AP group 1 are all operating in thin AP mode.

[0041] Taking the vehicle-mounted AP1 as an example, the AC will send the associated command 1 to the trackside AP (e.g., trackside AP1) that has established a mesh connection with the vehicle-mounted AP1.

[0042] After receiving the association command 1, the trackside AP1 will forward the association command 1 to the vehicle-mounted AP with which it has established a Mesh connection.

[0043] Subsequently, the onboard AP1 will receive association command 1, and then initiate an association process with the AC through the mesh link established with the trackside AP1. That is, the onboard AP1 establishes a CAPWAP tunnel with the AC through the mesh link established with the trackside AP1. The specific association process is existing technology and will not be described in detail here.

[0044] Next, after the AC connects to the onboard AP1, it will send a query request to the onboard AP1 via the trackside AP1 to inquire about the version number of the onboard AP1. Subsequently, upon receiving the query response from the onboard AP1 via the trackside AP1, which carries the version number of the onboard AP1, the AC will retrieve the version number of the onboard AP1 from the query response and determine whether the obtained version number of the onboard AP1 is inconsistent with the version number of the AC. If the determination result is not, then the AC will issue its version to the onboard AP1 via the trackside AP1, and the onboard AP1 will upgrade its version based on the AC's version.

[0045] After the onboard AP1 completes its version upgrade and reconnects to the AC via the trackside AP, the AC will also determine whether the configuration information corresponding to the onboard AP group 1 is stored locally. If the result is yes, the AC will also send the configuration information to the onboard AP1 via the trackside AP1, and the onboard AP1 will update its local configuration information based on the configuration information.

[0046] In other words, once the vehicle-mounted APs in vehicle-mounted AP group 1 are associated with the AC, the AC can manage these vehicle-mounted APs just like it manages existing trackside APs, without the need for administrators to manually manage and maintain these vehicle-mounted APs.

[0047] Furthermore, in this embodiment of the application, after the onboard AP is associated with the AC through a trackside AP with which it has established a mesh connection, the AC can also perform the following operations:

[0048] If it is determined that the version number of the obtained vehicle-mounted AP is consistent with the version number of the target version and that configuration information is stored locally, then the configuration information is sent from the trackside AP to the vehicle-mounted AP so that the vehicle-mounted AP can update its local configuration information based on the configuration information.

[0049] Additionally, if the AC determines that the version number of the obtained vehicle AP is consistent with the version number of the target version and no configuration information is stored locally, then the AC will not take any action in this case.

[0050] Furthermore, in this embodiment of the application, after the vehicle-mounted AP is associated with the AC through a trackside AP with which it has established a mesh connection, the AC can also perform the following operations:

[0051] After the vehicle-mounted AP successfully connects to the AC via the trackside AP that has established a Mesh connection with it, the trackside AP sends a working mode change command to the vehicle-mounted AP, instructing the vehicle-mounted AP to change its working mode to thin AP mode. The vehicle-mounted AP then changes its working mode to thin AP mode according to the working mode change command.

[0052] By performing the above operation procedures, these onboard APs in the onboard AP group can no longer operate in fat AP mode, but in thin AP mode. In this case, these onboard APs can be deployed by the administrator in the subway depot as trackside APs, or they can be deployed by the administrator in other locations.

[0053] In addition, in this embodiment of the application, after the vehicle-mounted AP is associated with the AC through a trackside AP with which it has established a mesh connection, the AC can also perform the following operations:

[0054] After the vehicle-mounted AP successfully associates with the AC through the trackside AP that has established a Mesh connection with it, if the association command is detected to have been deleted by the administrator, the trackside AP will then perform a deassociation operation on the vehicle-mounted AP.

[0055] By performing this procedure, the AC can flexibly manage the vehicle-mounted APs in the vehicle-mounted AP group. Here, the administrator can delete the above-mentioned association commands according to actual needs.

[0056] In this operation process, when the AC performs the deassociation operation on the vehicle-mounted AP through the trackside AP, the specific implementation process is as follows: the AC disconnects the vehicle-mounted AP and uses the CAPWAP tunnel established between the trackside AP and the AC.

[0057] As can be seen from the above technical solutions, in this embodiment of the application, the administrator no longer needs to manually manage the onboard APs working in fat AP mode in the subway depot. Instead, the AC actively notifies the onboard APs working in fat AP mode in the locally configured onboard AP group through the relevant trackside APs of the association instructions entered by the administrator. The onboard APs then associate with the AC through the relevant trackside APs, thereby enabling the AC to manage these onboard APs, which greatly saves manpower costs.

This allows each trackside AP to forward the association instruction to the corresponding vehicle AP, and the corresponding vehicle AP to initiate the association process to the AC. The working mode of each vehicle AP is fat AP mode, and the working mode of the trackside AP that has established a Mesh connection with each vehicle AP is thin AP mode.

[0061] After the onboard AP completes its version upgrade and reconnects to the AC via the trackside AP, if the configuration information corresponding to the onboard AP group is stored locally, the trackside AP will send the configuration information to the onboard AP so that the onboard AP can update its local configuration information based on the configuration information.

[0068] Preferably, the device further includes:

[0069] Third Management Module Figure 2 (Not shown in the image) is used to send a working mode change command from the vehicle-mounted AP to the vehicle-mounted AP after the vehicle-mounted AP has successfully associated with the AC through the trackside AP that has established a Mesh connection with the vehicle-mounted AP.

If the association command is detected to have been deleted by the administrator, the trackside AP will then perform a deassociation operation on the vehicle-mounted AP.

[0072] As can be seen from the above technical solutions, in this embodiment of the application, the administrator no longer needs to manually manage the onboard APs working in fat AP mode in the subway depot. Instead, the AC actively notifies the onboard APs working in fat AP mode in the locally configured onboard AP group through the relevant trackside APs of the association instructions entered by the administrator.
