Abstract

The present invention allows any number of mobile units to roam between a large numbers of sub-networks, each with a large number of access points (tens of thousands or more total access points), with minimal direct administration effort. A hierarchy of management servers may be used across the multiple sub-networks, which can be under the control of multiple entities. The invention provides the capability for the mobile units to authenticate the access points associated with, to ensure they are both authorized and managed. Peer-to-peer and ad hoc associations between mobile units are managed as welt. The invention may enforce a number of association policies such as, for example, forcing the mobile unit to only associate with access points or mobile units on a previously set mandatory association list, providing the mobile unit with a list of preferred access points to associate with, but allowing association with other access points, or providing the mobile unit with a excluded association list of access points or mobile units it is not to associate with.
