Apparatus and method for conducting a push-to-talk (PTT) call with a voice over IP (VOIP) communications device
View Patent ↗An apparatus and method for conducting a Voice Over Internet Protocol (VOIP) push-to-talk (PTT) call is disclosed. In an embodiment of the apparatus of the present invention, the apparatus includes a communications device coupled to a service provider network. The communications device includes a processor which converts a PTT communication from a first format to a second format. In an embodiment of a method of the present invention, the method includes converting a PTT communication from a first format to a second format by the processor of the communications device coupled to the service provider network.
1. An apparatus for conducting a Voice Over Internet Protocol (VOIP) push-to-talk (PTT) call, comprising:
a mobile dispatch communications device coupled to a first service provider network which uses a dispatch communications format, wherein the mobile dispatch communications device includes a processor which converts a PTT communication from a dispatch communications format to a VOIP format, translates a PTT identifier for a second communications device to a translated VOIP identifier of the second communications device, and transmits the communication in the VOIP format and the translated VOIP identifier to a second service provide network which uses the VOIP format and which is in communication with the first service provide network.
2. The apparatus of claim 1 , wherein the dispatch communications format is an Integrated Digital Enhanced Network (iDEN) format.
3. The apparatus of claim 1 , wherein the dispatch communications format is a Code Division Multiple Access (CDMA) format.
4. The apparatus of claim 1 , wherein the processor utilizes standard VOIP encoding, encapsulating, and transmission protocols when converting the PTT communication from the dispatch communications format to the VOIP format.
5. The apparatus of claim 4 , wherein the second communications device is coupled to the second service provider network, wherein the second communications device is a VOIP communications device which uses the VOIP format, wherein the second communications device conducts a VOIP PTT call with the mobile dispatch communications device, and wherein the second communications device includes the standard VOIP encoding, encapsulating, and transmission protocols.
6. The apparatus of claim 5 , wherein the mobile dispatch communications device is a cell phone and the second communications device is a personal computer.
7. The apparatus of claim 1 , wherein the mobile dispatch communications device further includes an Internet Protocol (IP) address conversion table to correlate the PTT identifier of the second communications device and the translated VOIP identifier of the second communications device.
8. The apparatus of claim 1 , wherein the mobile dispatch communications device is a cell phone.
9. A method for conducting a Voice Over Internet Protocol (VOIP) push-to-talk (PTT) call, comprising the steps of:
converting a PTT communication from a dispatch communications format to a VOIP format by a processor of a mobile dispatch communications device coupled to a first service provider network which uses a dispatch communications format,
translating a PTT identifier for a second communications device to a translated VOIP identifier of the second communications device; and
transmitting the communication in the VOIP format and the translated VOIP identifier to a second service provide network which uses the VOIP format and which is in communication with the first service provide network.
10. The method of claim 9 , wherein the dispatch communications format is an Integrated Digital Enhanced Network (iDEN) format.
11. The method of claim 9 , wherein the dispatch communications format is a Code Division Multiple Access (CDMA) format.
12. The method of claim 9 , wherein the processor utilizes standard VOIP encoding, encapsulating, and transmission protocols when converting the PTT communication from the dispatch communications format to the VOIP format.
13. The method of claim 12 , wherein the a second communications device is coupled to the second service provider network, wherein the second communications device is a VOIP communications device which uses the VOIP format, wherein the second communications device conducts a VOIP PTT call with the mobile dispatch-communications device, and wherein the second communications device includes the standard VOIP encoding, encapsulating, and transmission protocols.
14. The method of claim 13 , wherein the mobile dispatch communications device is a cell phone and the second communications device is a personal computer.
15. The method of claim 9 , wherein the mobile dispatch communications device further comprises an Internet Protocol (IP) address conversion table to correlate the PTT identifier of the second communications device and the translated VOIP identifier of the second communications device by the processor of the mobile dispatch communications device.
16. The method of claim 9 , wherein the mobile dispatch communications device is a cell phone.
