Federated multiprotocol communication
First Claim
1. For use in a system comprising at least a first wireless access point that uses a first air interface protocol and a second wireless access paint that uses a second air interface protocol, wherein the first and second wireless access points are both coupled to an Internet, a mobile unit communicates via the Internet at a transport layer or above with a roam management server system to facilitate a system-level roam operation from the first wireless access point to the second wireless access point, and the mobile unit couples to the Internet using a first connection via the first wireless access point prior to the system-level roam operation, a method comprising:
- receiving at the roam management server system an indication that the mobile unit is in a radio contact range of the second wireless access point;
determining whether a second connection between the mobile unit and the second wireless access point is preferable to the first connection, wherein the determining is performed by the roam management server system in accordance with an optimization strategy; and
sending from the roam management server system to the mobile unit an indication to switch from the first connection to the second connection in the event that the roam management server system determines that the second connection is preferable.

Abstract
Methods, apparatus, and business techniques are disclosed for use in distributed communication systems comprising a plurality of communication protocols. In one embodiment a first air interface is used to initiate communication between a wireless client and a remote server at least partially using a first wireless access point. The server sends the wireless client a stub of a distributed object. The stub is used to instantiate an object class. The object class defines an interface that the remote client can use to communicate with the remote server using an upper layer interface. The distributed object stub also provides an implementation of a software radio configuration for a set of lower protocol layers in a second air interface. The wireless client can thereby communicate with a second wireless access point using said second air interface protocol. Exemplary embodiments of the present invention are disclosed that focus on toll-tag and electronic-commerce related highway systems, distributed federated wireless access systems, and wide area wireless system capacity augmentation.
