The components of embodiments of the present invention generally described and illustrated in the figures herein may be arranged and designed in a wide variety of different configurations.
Thus, the following detailed description of the embodiments of the present invention, presented in the figures, is not intended to limit the scope of the invention, as claimed, but is merely representative of selected embodiments of the invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
It should be noted that: like reference numbers and letters refer to like items in the following figures, and thus, once an item is defined in one figure, it need not be further defined and explained in subsequent figures.
Referring to fig. 1, fig. 1 is an interaction diagram of an access management device (AC) 100 and at least two wireless Access Points (APs) 200 according to a preferred embodiment of the present invention. The terminal device 300 may associate with the AP200 in a wireless communication manner, and perform data transmission and reception.
In this embodiment, a terminal roaming management method applied to the AC100 shown in fig. 1 is provided, where the AC100 determines whether to allow the terminal device 300 to roam according to the received signal strength between the APs 200 currently associated with the terminal device 300 and the received signal strength between the APs 200 to be associated when receiving a roaming association request.
In this embodiment, the AC100 records a first Received Signal Strength (RSSI) of the terminal device 300 that is currently associated with the AP 200.
Optionally, the AC100 includes a reporting period configuration interface, and the AC100 may receive a reporting period defined by a user through the reporting period configuration interface, and issue a signal strength reporting period to the AP200, so that the AP200 periodically reports the received signal strength of the terminal device 300 accessing the AP200 according to the signal strength reporting period.
The AC100 receives the received signal strength of the associated terminal device 300 periodically transmitted by the AP 200.
Optionally, in this embodiment, the AP200 reports, according to the signal strength reporting period, the received signal strength of the terminal device 300 associated with the AP200 to the AC100 through a Control And Provisioning of Wireless Access Point (CAPWAP) event message.
The AC100 records the received signal strength of the terminal device 300 received the last time as the first received signal strength of the terminal device 300.
Referring to fig. 2, in conjunction with the recorded first received signal strength, the AC100 manages terminal roaming through the following steps, which will be described in detail below.
Step S110, receiving an association request sent by the terminal device 300 through the AP200 to be associated, where the association request includes a second received signal strength between the terminal device 300 and the AP200 to be associated.
In this embodiment, the AP200 to be associated receives an 802.11 association request initiated by a terminal, and sends the association request to the AC100 for processing after encapsulating the association request through a CAPWAP protocol, where a wireless data ieee80211RSSI field in a header of a CAPWAP message carries a second received signal strength between the terminal device 300 and the AP200 to be associated.
Referring to fig. 3, in the present embodiment, the method further includes step 109.
Step S109, determine whether the association request is a roaming association request, where the roaming association request is an association request initiated when the associated terminal device 300 needs to roam from the currently associated AP200 to another AP200 to be associated.
If the association request is a roaming association request, step S120 is performed.
If the association request is the association request sent by the terminal device 300 for the first time, the process proceeds to step S150.
Step S120, calculating a signal strength difference between the second received signal strength and the first received signal strength.
In this embodiment, the AC100 further includes a roaming threshold configuration interface, and the AC100 may receive a preset roaming threshold configured by a user in advance through the roaming threshold configuration interface.
The AC100 compares the signal strength difference between the second received signal strength and the first received signal strength with the preset roaming threshold after calculating the signal strength difference.
If the signal strength difference is greater than the predetermined roaming threshold, step S130 is performed.
If the signal strength difference is not greater than the predetermined roaming threshold, step S140 is performed.
Step S130, responding to the roaming association request of the terminal device 300, allowing the terminal device 300 to associate with the AP200 to be associated.
In this embodiment, if the signal strength difference is greater than the preset roaming threshold, it is determined that the terminal device 300 has reached the roaming condition, and the AC100 responds to the roaming association request and sends a notification to the corresponding AP200 to be associated, so as to allow the terminal device 300 to associate with the AP200 to be associated.
Step S140, not responding to the roaming association request of the terminal device 300, rejecting the association between the terminal device 300 and the AP200 to be associated.
In this embodiment, if the signal strength difference is not greater than the preset roaming threshold, it is determined that the terminal device 300 does not satisfy the roaming condition, and the AC100 does not respond to the roaming association request, the corresponding AP200 to be associated rejects the association between the terminal device 300 and the AP200 to be associated.
Based on the above design, the AC100 performs roaming control of the terminal device 300, and does not perform association when the terminal device 300 does not satisfy the roaming condition, so that the AC100 frequently issues an instruction to allow the AP200 to allow the terminal device 300 to perform association operation when the terminal device 300 frequently roams, thereby reducing the device burden and avoiding adverse effects on the networking experience of the terminal device 300 due to frequent switching of the AP 200.
Step S150, responding to the association request, allowing the terminal device 300 to associate with the AP200 to be associated.
In this embodiment, if the association request is an association request sent by the terminal device 300 for the first time, the AC100 performs general processing on the association request, and directly allows the terminal device 300 to associate with the AP200 to be associated.
Referring to fig. 4, the present embodiment further provides an AC100, where the AC100 includes: a first receiving module 111, a calculating module 112 and a first control module 113.

Optionally, in this embodiment, the recording module 115 is further configured to, when it is detected that the terminal device 300 is offline, clear the recorded first received signal strength of the terminal device 300.
Optionally, referring to fig. 5 again, the AC100 further includes a sending module 116.
The issuing module 116 is configured to issue a signal strength reporting period to the AP200, so that the AP200 periodically reports the received signal strength of the terminal device 300 accessing the AP200 according to the signal strength reporting period.
Optionally, referring to fig. 5 again, the AC100 further includes a second control module 117.
The second control module 117 is configured to, when the association request is an association request sent by the terminal device 300 for the first time, respond to the association request, and allow the terminal device 300 to associate with the AP200 to be associated.
