Hierarchical data collection network supporting packetized voice communications among wireless terminals and telephones
First Claim
1. A non-transitory computer-readable medium having stored thereon a computer program having a plurality of code sections for operating a system supporting voice communication via a packet network, the code sections executable by a processor for causing the processor to perform the operations comprising:
- receiving, via the packet network, a message requesting setup of a voice call, the message comprising a destination address;
sending, via a conventional telephone switching network link, signals based upon the destination address requesting setup of the voice call;
receiving, via the conventional telephone switching network link, signals representing call status;
establishing communication of signals representative of voice between the packet network and the conventional telephone switching network link, if call status indicating establishment of a connection is received; and
refraining from establishing communication of signals representative of voice between the packet network and the conventional telephone switching network link, if call status indicating establishment of a connection is not received.

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.

29. A non-transitory computer-readable medium having stored thereon a computer program having a plurality of code sections for operating a telephony device, the code sections executable by a processor for causing the processor to perform the operations comprising:
-
receiving a message requesting setup of a voice call from a communication system via a packet network, the received message indicative of;
the communication system receiving an indication of an incoming voice call and a destination address, and the communication system identifying a packet network address for the telephony device based upon the destination address; andsending a message indicating call status to the communication system via the packet network, the sent message to cause the communication system to; establish voice communication between the packet network and the conventional telephone switching network link, if call status indicating establishment of a connection is received; and refrain from establishing voice communication between the packet network and the conventional telephone switching network link, if call status indicating establishment of a connection is not received. - View Dependent Claims (30, 31, 32, 33, 34, 35, 36)

37. A non-transitory computer-readable medium having stored thereon a computer program having a plurality of code sections for operating a communication terminal, the code sections executable by a processor for causing the processor to perform the operations comprising:
-
sending, from the communication terminal via a packet network, a message requesting information for routing a voice call from the communication terminal to a telephony device of a convention telephone switching network via a second communication terminal of the packet network, the second communication terminal supporting voice communication between the packet network and a conventional telephone switching network; receiving, via the packet network, the routing information; initiating establishment of the voice call between the communication terminal of the packet network and the telephony device of the conventional telephone switching network, using the routing information; communicating signals representative of voice between the communication device and the telephony device via the packet network, the second communication terminal, and the conventional telephone switching network, if a voice call connection is successfully established; and signaling a user of the communication device, if a voice call connection between the communication device and the telephony device via the packet network, the second communication terminal, and the conventional telephone switching network, is not able to be established. - View Dependent Claims (38, 39, 40, 41, 42, 43, 44, 45)
