A packet-based, hierarchical communication system, arranged in a spanning tree configuration, is described in which wired and wireless communication networks exhibiting substantially different characteristics are employed in an overall scheme to link portable or mobile computing devices. The network accommodates real time voice transmission both through dedicated, scheduled bandwidth and through a packet-based routing within the confines and constraints of a data network. Conversion and call processing circuitry is also disclosed which enables access devices and personal computers to adapt voice information between analog voice stream and digital voice packet formats as proves necessary. Routing pathways include wireless spanning tree networks, wide area networks, telephone switching networks, internet, etc., in a manner virtually transparent to the user. A voice session and associate call setup simulates that of conventional telephone switching network, providing well-understood functionality common to any mobile, remote or stationary terminal, phone, computer, etc.

1. Field of the Invention
The present invention relates generally to data communication networks having a plurality of wired and/or wireless access servers configured to support remote processing, data storage and voice communication. More specifically, this invention relates to the intelligent routing of packetized voice communication between telephones and radio terminals through wireless and hardwired channels in a data processing network.
While the present invention is described herein with reference to illustrative embodiments for particular applications, it should be understood that the invention is not limited thereto. Those having ordinary skill in the art and access to the teachings provided herein will recognize additional modifications, applications and embodiments within the scope thereof and additional fields in which the present invention would be of significant utility.
FIG. 1A is a diagrammatic illustration of a hierarchal communication system built in accordance with the present invention.
FIG. 1B is a diagrammatic illustration of another hierarchal communication system built in accordance with the present invention.
FIG. 1C is a diagrammatic illustration of still another hierarchal communication system built in accordance with the present invention.
FIG. 1A illustrates a hierarchical communication system 10 within a building in accordance with the present invention. The illustrated hierarchical communication system 10 includes a local area network (LAN) for maintaining typical communication flow within the building premises, herein referred to as a premises LAN. The premises LAN is designed to provide efficient end-to-end routing of information among hardwired and wireless, stationary and roaming devices located within the hierarchical communication system 10.
The premises LAN consists of an infrastructure network comprising radio base stations, i.e., wireless access points 15, and a data base server 16 which may be part of a more extensive, wired LAN (not shown). Herein, base stations which participate in routing and relaying data throughout the communication network are referred to as “access points.” If they also participate in the storage or migration of data and program code or in local processing, the base stations are referred to herein as “access servers.” As will become apparent below, an access point may be modified with additional circuitry and/or programming resources to become an access server. Additionally, access servers and access points are both referred to herein as “access devices.”
The access points 15 may communicate with each other via hardwired links, such as Ethernet, RS232, etc., or via wireless (radio frequency) links. A plurality of roaming terminal devices, such as a roaming computing device 20, participate in the premises LAN of the hierarchical communication network 10 to exchange information with: 1) other roaming computing devices; 2) the data base server 16; 3) other devices which might be associated with data base server 16 (not shown); and 4) any other devices accessible via the premises LAN (not shown). A roaming computing device can be, for example, a hand-held computer terminal or vehicle mounted computer terminal (vehicle terminal).
