Embodiments of the invention

[0022] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It is understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

[0023] FIG. 1 is a flowchart showing an implementation of a method for extending the number of WLAN IDs according to an embodiment of the present invention, which is described in detail as follows:

[0024] In step S101, when receiving the request information for adding the WLAN, determining to increase the access point corresponding to the request information of the WLAN, and establishing a mapping table corresponding to the access point.

[0025] The executive body of the embodiment of the present invention may be an AC. When the WLAN ID that needs to be configured on the AC is more than 16 吋, for example, the AC needs to be configured with 512 different WLANs, the virtual mapping WLAN ID provided by the embodiment of the present invention is required to implement the WLAN ID extension.

In the embodiment of the present invention, when the request information for adding the WLAN is sent by the web (web) network management system of the AC, the access point corresponding to the request information of the WLAN is determined, and the presence or absence of the access point is determined. The mapping table corresponding to the ingress point, if not, establishes a mapping table corresponding to the access point, so as to record the mapping relationship between the real WLAN ID and the virtual WLAN ID through the mapping table.

[0027] As an embodiment of the present invention, the AC establishes a mapping table for each AP to record the real WLAN.

[0031] The WLAN ID corresponding to the access point ranges from 1 to 16. For example, multiple WLANs for the API If the WLAN ID 1 in the ID is idle, the WLAN ID 1 can be determined as a virtual WLAN.

ID, and establish a mapping relationship between the real WLAN ID 100 and the virtual WLAN ID 1.

[0032] Table 1 shows an example of a mapping table corresponding to the API, and Table 2 shows an example of a mapping table corresponding to the AP2.

Table 1

[] [Table 1]

[0035] In step S104, the mapping relationship between the real WLAN ID and the virtual WLAN ID is recorded in the mapping table. [0036] For example, the mapping relationship between the real WLAN ID 100 and the virtual WLAN ID 1 is recorded in the mapping table.

[0037] After the mapping relationship between the real WLAN ID and the virtual WLAN ID is recorded in the mapping table, the method further includes: [0038] The virtual WLAN ID is placed in a busy state.

[0039] In the embodiment of the present invention, the mapping table will be associated with the real WLAN.

The virtual WLAN ID of the ID establishing mapping relationship is placed in a busy state. For example, the virtual WLAN ID 1 that is mapped to the real WLAN ID 100 is placed in a busy state.

[0040] In step S105, the virtual WLAN ID is sent to the access point, so that the access point is bound to the real WLAN.

The WLAN corresponding to the ID.

[0041] For example, the virtual mapped virtual WLAN ID 1 is sent to the API, so that the WLAN corresponding to the virtual WLAN ID 100 is implemented.

[0042] When the AC receives the response of the virtual WLAN ID corresponding to the API, the virtual WLAN is found from the mapping table.

The real WLAN ID 100 corresponding to the ID 1 transmits the message according to the WLAN corresponding to the real WLAN ID 100.

[0043] The embodiment of the present invention implements the extension of the WLAN ID, so that the AC can configure 512 or more WLANs.

The WLAN ID can range from 1 to 512 or even wider.

[0053] In step S209, the WLAN update information is sent to the access point corresponding to the mapping table, so that the access point updates the WLAN corresponding to the virtual WLAN ID according to the WLAN update information.

[0054] For example, when receiving the request information of the WLAN of the real WLAN ID 100 of the update API delivered by the web management of the AC, the virtual WLAN ID corresponding to the real WLAN ID 100 is found from the mapping table, so that the API is updated according to the WLAN.
