Abstract

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.

22. A computer-readable storage having stored therein instructions executable by a processor to cause the processor to perform a series of steps of a method for operating a communication device, the method comprising:

receiving from a communication system via a wireless packet communication link a message requesting setup of a voice call, the voice call corresponding to an indication received by the communication system via one of one or more communication links, each communication link having an associated type; and

sending to the communication system via the wireless packet communication link a message indicating call status, where the message indicating call status comprises information to cause the communication system to establish voice communication between the wireless packet communication link and the one communication link based upon the associated type of the one communication link.

23. The computer-readable storage of claim 22, where the message indicating call status comprises information to cause the communication system to refrain from establishing voice communication between the wireless packet communication link and the one communication link.

24. The computer-readable storage of claim 22, where the wireless packet communication link uses an Internet protocol (IP).

27. The computer-readable storage of claim 26, where the one communication link is an analog communication link.

28. The computer-readable storage of claim 22, where the message indicating call status comprises information to cause the communication system to establish voice communication between the wireless packet communication link and the one communication link by, at least in part:

converting information received from the wireless packet communication link for transmission via the one communication link; and

converting information received from the one communication link for transmission via the wireless packet communication link.

29. The computer-readable storage of claim 22, where the message indicating call status comprises information to cause the communication system to establish voice communication between the wireless packet communication link and the one communication link by, at least in part, establishing communication of data.
