Abstract

Disclosed is a method of transitioning from a facsimile session to a voice session during a call between a wireless user and a facsimile machine. The method comprises sending a procedure interrupt request, sending a procedure interrupt response, sending a procedure interrupt confirmation, negotiating to a voice service option, and then beginning the voice service option.

Claims

1. A method to transition from a fax transmission mode to a voice transmission mode between a first terminal and a second terminal, one of the terminals being a wireless terminal, the method comprising:

transmitting a request from the first terminal to the second terminal to transition from a fax transmission mode to a voice transmission mode;

transmitting a response from the second terminal to the first terminal to indicate the second terminal accepts the request to transition from fax to voice transmission mode; and

transmitting an authorization from the first terminal to the second terminal to cause the first terminal and the second terminal to change from fax to voice transmission mode.

2. The method of claim 1 wherein the both terminals are mobile terminals.

4. The method of claim 1 wherein the transmitting a response further comprises transmitting an interrupt response.

5. The method of claim 1 wherein the transmitting an authorization further comprises sending a confirmation of the interrupt request.

3. The method of claim I wherein the transmitting the request further comprises transmitting an interrupt request.

6. A method of performing a transition from a facsimile session to a voice session during a single call between a mobile terminal and a facsimile machine, the method comprising:

requesting a session interrupt,

receiving a response to the session interrupt request,

sending a confirmation of the session interrupt request, and

negotiating to the voice session.

7. A method of claim 6 further comprising:

receiving a request procedure interrupt signal,

sending a procedure interrupt request signal to interrupt the facsimile session upon receipt of the request procedure interrupt signal,

receiving a procedure interrupt response signal,

sending a transition to voice signal to the mobile terminal upon receipt of the procedure interrupt response signal,

receiving a cellular voice request signal, and

sending procedure interrupt confirmation signal upon receipt of the cellular voice request signal.

8. The method of claim 7 wherein the request procedure interrupt signal is selected from the group consisting of a <

DLE>

<

pri>

signal, a AT+FPS signal, and a +FDR signal.

9. The method of claim 7 wherein the procedure interrupt request signal is selected from the group consisting of a PRI-Q signal, a PIP signal, and a PIN signal.

10. The method of claim 7 wherein the procedure interrupt response signal is selected from the group consisting of a PIP signal, a PIN signal, and a PRI-Q signal.

11. The method of claim 7 wherein the transition to voice signal is a +FVO signal.

12. The method of claim 7 wherein the cellular voice request signal is an <

EM>

<

Voice Request>

signal.

13. The method of claim 7 wherein the procedure interrupt confirmation signal is a PRI-Q signal, a PIP signal, and a PIN signal.

14. A method of claim 6 further comprising:

receiving a procedure interrupt request signal,

sending a transition to voice signal to interrupt the facsimile session upon receipt of the procedure interrupt signal,

receiving a cellular voice request signal,

sending a procedure interrupt response upon receipt of the cellular voice request signal, and

receiving a procedure interrupt confirmation.

15. The method of claim 14 wherein the procedure interrupt request signal is selected from the group consisting of a PIP signal, a PIN signal, and a PRI-Q signal.

16. The method of claim 14 wherein the transition to voice signal is a +FVO signal.

17. The method of claim 14 wherein the cellular voice request signal is an <

EM>

<

Voice Request>

signal.

18. The method of claim 14 wherein the procedure interrupt response signal is selected from the group consisting of a PRI-Q signal, a PIP signal, and a PIN signal.

19. The method of claim 14 wherein the procedure interrupt confirmation signal is selected from the group consisting of a PIP signal, a PIN signal, and a PRI-Q signal.

20. A telecommunications system, comprising:

a base station adapted to communicate with a mobile terminal, wherein the mobile terminal is capable of sending data used by fax applications,

a mobile switching center in communication with the base station for causing the base station to communicate with the mobile terminal,

a inter-working function unit coupled to the mobile switching center and in communication with a fax terminal through a PSTN,

wherein the inter-working function unit comprises;

a means for receiving a request procedure interrupt signal,

a means for sending a procedure interrupt request signal to interrupt the facsimile session upon receipt of the request procedure interrupt signal,

a means for receiving a procedure interrupt response signal,

a means for sending a transition to voice signal to the mobile terminal upon receipt of the procedure interrupt response signal,

a means for receiving a cellular voice request signal, and

a means for sending procedure interrupt confirmation signal upon receipt of the cellular voice request signal.

21. A telecommunications system, comprising:

a base station adapted to communicate with a mobile terminal, wherein the mobile terminal is capable for sending data used by fax applications,

a mobile switching center in communication with the base station for causing the base station to communicate with the mobile terminal,

a inter-working function unit coupled to the mobile switching center and in communication with a fax terminal through a PSTN,

wherein the inter-working function unit comprises;

a means for receiving a procedure interrupt request signal,

a means for sending a transition to voice signal to interrupt the facsimile session upon receipt of the procedure interrupt signal,

a means for receiving a cellular voice request signal,

a means for sending a procedure interrupt response upon receipt of the cellular voice request signal, and

a means for receiving a procedure interrupt confirmation.
