Embodiment 1

[0025] see figure 1 A method for collecting wireless network data provided in Embodiment 1 is executed by a data collection device associated with an AP, and the method specifically includes: operation 11-operation 13.

[0026] In operation 11, a data acquisition command is invoked.

[0027] Wherein, the data collection command may be a program, which is pre-set in the device for collecting wireless network data, and is used to trigger the device for collecting wireless network data to perform data collection. For example, when the device for collecting wireless network data is powered on and started, the data collection command is directly invoked; After the button is pressed, the device for collecting wireless network data invokes a data collection command according to the user's operation.

[0028] In operation 12, send a power saving notification message to the AP according to the data collection command, so that the data collection device enters a data collection mode. ...

Embodiment 2

[0056] Based on the foregoing embodiments, this embodiment provides another method for collecting wireless network data. In this embodiment, a special scheduling module can be set in the data collection device applying this method to periodically schedule the data collection command and the work command, so that the data collection device can periodically alternate between the working mode and the data collection mode . Among them, the scheduling module can be the main program, and the data collection command and the work command can be subroutines. As long as the data collection device is in the open state, the scheduling module can periodically schedule the data collection command and the work order, so that the data collection device is periodically in the data collection mode. mode and working mode. When the work command is executed, the WIFI driver is triggered to send a power-saving cancellation message such as a power-saving-poll frame, and the value of the power manag...

Embodiment 3

[0068] see image 3 , a device for collecting wireless network data provided in this embodiment is set in a data collection device associated with an access point AP, and specifically includes: a scheduling module 31 , a collection trigger module 32 , a scanning module 33 and a data collection module 34 .

[0069] The scheduling module 31 is used to call the data collection command, for details, refer to the description in the above method embodiment.

[0070] The collection triggering module 32 is configured to send a power saving notification message to the AP according to the data collection command, so that the data collection device enters a data collection mode. Here, the function of the collection trigger module 32 to send the power saving notification message can be realized by the driving module of MAC802.11. For example, the driving module of MAC802.11 sends a power saving notification message triggered by a data collection command.

[0071] The scanning module 33 ...

Abstract

The invention discloses a method and a device for acquiring wireless network data. The method for acquiring the wireless network data is executed by data acquisition equipment associated to an access point AP and comprises steps as follows: a data acquisition command is called; a power-saving announcement message is sent to the AP according to the data acquisition command, so that the data acquisition equipment enters a data acquisition mode; in the data acquisition mode, the data acquisition equipment keeps an associated state with the AP for WIFI scanning, wireless network signals on different channels are obtained, and wireless network data are acquired according to the wireless network signals on different channels. Wireless deployment of the data acquisition equipment is realized, the data acquisition quantity is effectively increased, the system stability is effectively improved, and the deployment cost is saved.

Description

technical field [0001] Embodiments of the present invention relate to data collection technologies, and in particular to a method and device for collecting wireless network data. Background technique [0002] In the field of network management and monitoring, data collection is mainly to capture and analyze data packets to obtain real-time and effective network status information, so as to facilitate the analysis and management of network operating conditions. [0003] With the popularization of wireless fidelity (Wireless Fidelity, WIFI for short), data collection is also extended to collect wireless network data. [0004] At present, when a device for collecting WIFI wireless network data (referred to as a data collection device) collects wireless network data, it scans various channels through WIFI to obtain wireless network data. Then, the data acquisition device is uploaded to the backend server or controller by wire. This requires that there must be a wired access ne...
