  • Wireless roaming method and access controller
    Patent number: 9173083
    Abstract: According to an example, a reauthentication or reassociation message carrying a roaming group information may be received from a wireless client (STA) by an AC when the STA is roaming. In addition, the AC may determine, according to the roaming group information and the received reauthentication or reassociation message, whether the STA is roaming between roaming groups or within a roaming group. In response to a determination that the roaming is between roaming groups, an extension authentication protocol (EAP) reauthentication process may be initiated and in response to a determination that the roaming is within a roaming group, a Key Cache method may be adopted to authenticate the STA.
