Abstract
A wireless roaming method and related system are provided. The method is applicable to an access control device and includes: determining a moving direction of a mobile device that is in a first connection connecting with a first access point; establishing, by a second access point and in response to a determination that the moving direction meets a preset condition, a second connection connecting the mobile device with the second access point, and disconnecting, by the first access point, the first connection. The first access point and the second access point are both connected to the access control device, and have a same static address or a same Identity Resolving Key. This method allows the mobile device to securely and seamlessly roam within the coverage areas of different access points.
