Abstract

A system (20) for simplex dispatch of an information packet (22) utilizing a telecommunication network (24) is provided. The system (20) includes an origination unit (26), a server (42), and a destination unit (28). The origination unit (26) is configured to generate an origination packet (50) containing a voice frame (54), and to transmit the origination packet (50) utilizing a wireless non-circuit-switching service of network (24). The origination unit (26) and the server (42) are coupled through an origination cell site (36) of the network (24). The server (42) is configured to receive the origination packet (50), to convert the origination packet (50) to a destination packet (52) containing a voice frame (54) and/or a text frame (56), and to transmit the destination packet (52). The server (42) and the destination unit (28) are coupled through a destination cell site (46) of the network (24). The destination unit (28) is configured to receive the destination packet (52) utilizing a non-circuit-switching service of the network (24), and to present the contents of the destination packet (52) to a recipient (174).

Claims

1. A method of simplex information-packet dispatching utilizing a global telecommunication network, at least a portion of which provides cellular service, said method comprising:

a) transmitting an information packet containing an audio frame from an origination unit to an origination cell site of an origination cellular service of said global telecommunication network utilizing a wireless packet-switch service of said origination cellular service, wherein said information packet is configured as an origination packet within said origination unit, and wherein said origination unit is a digital cellular subscriber unit of said origination cellular service;

b) routing said information packet via said global telecommunication network from said origination cell site to a destination cell site of a destination cellular service of said global telecommunication network; and

c) receiving said information packet at a destination unit from said destination cell site utilizing a wireless packet-switch service of said destination cellular service, wherein said information packet is configured as a destination packet within said destination unit, and wherein said destination unit is a digital cellular subscriber unit of said destination cellular service;

wherein

said destination unit is one of a plurality of destination units,

said transmitting includes group dispatching said information packet to each of said destination units; and

said receiving is repeated in each of said destination units.

2. A simplex dispatching method as claimed in claim 1 additionally comprising, prior to said transmitting activity, generating said origination packet in said origination unit.

3. A simplex dispatching method as claimed in claim 2 wherein said generating activity comprises:

producing an audio signal;

encoding said audio signal into said audio frame; and

enclosing said audio frame within said origination packet.

4. A simplex dispatching method as claimed in claim 1 additionally comprising, after said receiving activity, presenting said destination packet to a recipient at said destination unit.

5. A simplex dispatching method as claimed in claim 4 wherein said destination packet contains an audio frame and said presenting activity comprises:

extracting said audio frame from said destination packet;

decoding said audio frame into an audio signal; and

outputting said audio signal.

6. A simplex dispatching method as claimed in claim 5 wherein said outputting activity outputs said audio signal as an audible sound.

7. A simplex dispatching method as claimed in claim 6 wherein said presenting activity additionally comprises notifying said recipient of a presence of said audio signal.

8. A simplex dispatching method as claimed in claim 4 wherein said destination packet contains a text frame and said presenting activity comprises:

extracting said text frame from said destination packet;

decoding said text frame into a text signal; and

displaying said text signal as text.

9. A simplex dispatching method as claimed in claim 1 additionally comprising configuring said origination packet into said destination packet within a server.

10. A simplex dispatching method as claimed in claim 9 wherein said configuring activity comprises converting a logical address of said destination unit to a physical address of said destination unit.

11. A simplex dispatching method as claimed in claim 9 wherein said audio frame is a first audio frame, and wherein said configuring activity comprises converting said first audio frame to a second audio frame.

12. A simplex dispatching method as claimed in claim 9 wherein said configuring activity comprises, converting said audio frame to a text frame.

13. A simplex dispatching method as claimed in claim 1 additionally comprising:

generating, prior to said transmitting activity a), said information packet within said origination unit; and

allocating, after an inception of said generating activity, use of said packet-switch service for said transmitting activity a).

14. A simplex dispatching method as claimed in claim 1 wherein:

said method additionally comprises d) wirelessly routing said information packet from said origination unit to said origination cell site;

said routing activity b) comprises e) routing said information packet from said origination cell site to a server;

said routing activity b) additionally comprises f) routing said information packet from said server to said destination cell site; and

said method additionally comprises g) wirelessly routing said information packet from said destination cell site to said destination unit.

15. A simplex dispatching method as claimed in claim 14 wherein:

said server comprises a plurality of portions, wherein each of said portions is remotely separated from others of said portions, and wherein each of said portions communicates with others of said portions via a packet-switched network;

said routing activity e) routes said information packet to a first one of said portions of said server; and

said routing activity f) routes said information packet from a second one of said portions of said server.
