1. A computer method for performing a seamless handoff of a mobile device from an initial access point to a target access point in a wireless local access network, comprising the steps of:

  • assigning session data at a roaming server to the initial access point to establish an initial connection from the mobile device through the initial access point to the roaming server;

    detecting at the roaming server a triggering event that initiates a seamless transfer of the mobile device from the initial access point to the target access point; and

    seamlessly transferring at the roaming server assignment of the session data from the initial access point to the target access point to establish a target connection from the mobile device through the target access point to the roaming server based on the session data in response to the triggering event, thereby enabling the mobile device to use the session data to communicate with the roaming server in a continuous manner during the transfer.
