Embodiment 1

[0057] see figure 2 , figure 2 It is a flowchart of a method for identifying an access point identity provided in an embodiment of the present invention. Such as figure 2 As shown, the method may include:

[0058] Step 201: After receiving the message, the first access point obtains the BSSID in the message, and the BSSID includes the operator identifier of the second access point that sent the message and the access controller identifier of the second access point ;

[0059] Step 202: Compare the above-mentioned operator ID and access controller ID with the information stored in the first access point, if the above-mentioned operator ID is the same as the operator ID stored in the first access point, and the above-mentioned access controller If the identifier is the same as the controller identifier stored in the first access point, it is determined that the first access point and the second access point belong to the same jurisdiction.

[0060] Preferably, the BSSID ...

Embodiment 2

[0063] see image 3 , image 3 It is a flowchart of a method for identifying an access point identity provided in an embodiment of the present invention. This embodiment takes identifying the identity of a local access point as an example, where all local access points have a local unicast address. Such as image 3 As shown, the method may include:

[0064] Step 301, the AP collects the BSSID in the message sent by the surrounding access points, and the BSSID includes at least the operator identification and the access controller identification;

[0065] In the BSS, each AP can receive the messages sent by other APs around it, and obtain the carried BSSID from the messages, which is common knowledge of those skilled in the art. The specific process of BSSID in the message sent by the AP will not be introduced.

[0066] Among them, the operator ID is represented by the operator ID, and the value range of the operator ID is 0 to 4K-1, which occupies 12 bits; the access cont...

Embodiment 3

[0074] see Figure 4a , Figure 4a It is a flowchart of another method for identifying an access point identity provided in an embodiment of the present invention. Such as Figure 4a As shown, the method may include:

[0075] Step 401, the AP receives and stores the operator ID, AC ID, AP ID, and radio frequency identification (Radio ID) of the AP issued by the AC;

[0076] Such as Figure 4b As shown, in the BSS, one AC can manage multiple APs; generally, based on network capacity and compatibility considerations, an AP may have multiple radios; Each radio provides multiple VAP services.

[0077] Step 402, the AP receives the VAP identifier issued by the AC, if the value of the VAP identifier is 0, it is stored directly; if the value of the VAP identifier is not 0, the VAP identifier is decremented by 1 and stored;

[0078] The BSSID customized by this AP is shown in Table 2, and the customized BSSID actually identifies the wireless network structure.

Abstract

The embodiment of the invention relates to the technical field of communications, and discloses a method for identifying access point identity, a workstation roaming method and related equipment. The method comprises the following steps: after a first access point receives a message, acquiring a basic service set identifier (BSSID) in the message, wherein the BSSID comprises an operator identifier of a second access point transmitting the message and an access controller identifier at the second access point; and comparing the operator identifier and the access controller identifier with the information stored in the first access point, wherein if the operator identifier is identical to the operator identifier stored in the first access point and the access controller identifier is identical to the access controller identifier stored in the first access point, judging that the first access point and the second access point belong to the same extent of jurisdiction. The embodiment of the invention can decrease the occupation of the MAC address resources.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a method for identifying the identity of an access point, a roaming method for a workstation and related equipment. Background technique [0002] In a basic service set (Basic Service Set, BSS), an access point (Access Point, AP) is used to be responsible for communication of all workstations in the BSS. The AP can provide multiple network name access services for workstations, and each network name access service has different encryption, authentication methods, and other network parameter differences. Each network name access service body is called a virtual access point (Virtual Access Point, VAP), and each VAP is assigned a Basic Service Set Identification (BSSID) and network name. The BSSID of each VAP is represented by an applied global Media Access Control (MediaAccessControl, MAC) address. [0003] As the number of APs increases, the operator can use an access co...
