Abstract
A telecommunications architecture using ATM based technology is disclosed that supports wireless communications. Some embodiments of the present invention may provide a mechanism for hand-off, which has fewer costs and restrictions than other hand-off schemes the in the prior art. In one embodiment a plurality of virtual circuit identifiers is created such that each is unambiquously associated with the others. The virtual circuit identifiers are then transmitted to a wireless terminal, via a first radio port. Subsequently, the wireless terminal transmits one of the virtual circuit identifiers to second radio port.
