Abstract

A subscriber unit including an interface and a processor to transmit a first request to a wireless communication system by way of the interface to request a communication session in a first communication mode with one or more users; communicate with the one or more users by way of the interface in the communication session and in the first communication mode; transmit, while in the communication session, a second request to the wireless communication system by way of the interface to switch the first communication mode to a different second communication mode; and communicate with the one or more users by way of the interface in the communication session and in the second communication mode.

Claims

1. A method comprising:

transmitting a first request to a wireless communication system requesting a communication session in a first communication mode with one or more users;

while in the communication session, transmitting a second request to the wireless communication system to switch the first communication mode to a different second communication mode; and

communicating with the one or more users in the communication session and in the second communication mode.

2. The method of claim 1, wherein the first communication mode comprises a half-duplex communication mode.

3. The method of claim 2, wherein the second communication mode comprises a full-duplex communication mode.

4. The method of claim 1, wherein the first communication mode comprises a full-duplex communication mode.

5. The method of claim 4, wherein the second communication mode comprises a half-duplex communication mode.

6. The method of claim 1, further comprising changing RF resources to handle said second communication mode.

7. A subscriber unit comprising;

an interface; and

a processor to;

transmit a first request to a wireless communication system by way of the interface to request a communication session in a first communication mode with one or more users;

communicate with the one or more users by way of the interface in the communication session and in the first communication mode;

transmit, while in the communication session, a second request to the wireless communication system by way of the interface to switch the first communication mode to a different second communication mode; and

communicate with the one or more users by way of the interface in the communication session and in the second communication mode.

8. The subscriber unit of claim 7, wherein the first communication mode comprises a half-duplex communication mode.

9. The subscriber unit of claim 8, wherein the second communication mode comprises a full-duplex communication mode.

10. The subscriber unit of claim 7, wherein the first communication mode comprises a full-duplex communication mode.

11. The subscriber unit of claim 10, wherein the second communication mode comprises a half-duplex communication mode.

12. The subscriber unit of claim 7, wherein the interface comprises a radio frequency (RF) interface.

13. The subscriber unit of claim 7, wherein the interface comprises an external network interface.

14. The subscriber unit of claim 7, wherein said processor is adapted to change RF resources provided by said interface to handle said second communication mode.

15. A computer readable medium comprising one or more software modules to control a processor to:

transmit a first request to a wireless communication system to request a communication session in a first communication mode with one or more users;

communicate with the one or more users in the communication session and in the first communication mode;

transmit, while in the communication session, a second request to the wireless communication system by way of the interface to switch the first communication mode to a different second communication mode; and

communicating with the one or more users by way of the interface in the communication session and in the second communication mode.

16. The computer readable medium of claim 15, wherein the first communication mode comprises a half-duplex communication mode.

17. The computer readable medium of claim 16, wherein the second communication mode comprises a full-duplex communication mode.

18. The computer readable medium of claim 15, wherein the first communication mode comprises a full-duplex communication mode.

19. The computer readable medium of claim 18, wherein the second communication mode comprises a half-duplex communication mode.

20. The computer readable medium of claim 15, wherein said one or more software modules are adapted to control said processor to change RF resources to handle said second communication mode.

21. A method comprising:

receiving a first request from a wireless communication system requesting a communication session in a first communication mode with one or more users;

transmitting a first response to said first request to said wireless communication system, wherein said first response indicates an acceptance of said first request;

communicating with the one or more users in the communication session and in the first communication mode;

while in the communication session, receiving a second request from the wireless communication system to switch the first communication mode to a different second communication mode;

transmitting a second response to said second request to said wireless communication system, wherein said second response indicates an acceptance of said second request; and

communicating with the one or more users in the communication session and in the second communication mode.

22. The method of claim 21, wherein the first communication mode comprises a half-duplex communication mode.

23. The method of claim 22, wherein the second communication mode comprises a full-duplex communication mode.

24. The method of claim 21, wherein the first communication mode comprises a full-duplex communication mode.

25. The method of claim 24, wherein the second communication mode comprises a half-duplex communication mode.

26. The method of claim 21, further comprising changing RF resources to handle said second communication mode.

27. The method of claim 21, wherein transmitting said second response is performed automatically after receiving said second request.

28. A subscriber unit comprising;

an interface; and

a processor to;

receive a first request from a wireless communication system by way of said interface requesting a communication session in a first communication mode with one or more users;

transmit a first response to said first request to said wireless communication system by way of said interface, wherein said first response indicates an acceptance of said first request;

communicate with the one or more users in the communication session and in the first communication mode;
