METHODS AND APPARATUS FOR ROAMING IN A WIRELESS NETWORK

摘要

Methods and systems are provided for improving network connectivity utilizing a roaming procedure in which the mobile units are able to associate with multiple access ports during roaming. The mobile unit, while connected to one access port, associates with a second access port. While maintaining the connection to the first access port, the mobile unit performs various initialization procedures, including exchange of encryption keys, authentication, DHCP renewal, and the like. After a connection is established with the second access port, the mobile unit disconnects from the first access port. Thus, during the roaming process, the MU is connected to two APs at the same time for a short length of time.
