Abstract

Systems and methods are provided for setting up a push-to-talk group call in a wireless communications system 100. The call setup information in a call message 400 is established as potential targets 108-114 are identified on a wireless device 106 to reduce call setup time and overall system latency.

Claims

1. A method for setting up a push-to-talk (PTT) group communication, the method comprising:

detecting an indication of information for a PTT call parameter of the group communication;

adding the information to a call message in response to the detecting of the indication; and

receiving, after the information has been added to the call message, a validation of the information.

2. The method of claim 1, further comprising:

receiving an instruction to transmit the call message after the information has been added to the call message; and

transmitting the call message.

3. The method of claim 2, wherein the instruction to transmit the call message is indicated by detecting that a PIT button on a wireless device has been depressed.

4. The method of claim 1, wherein the information is a target address.

5. The method of claim 4;

wherein the validation of the information is indicated by detecting an input to select the target address for the group communication.

6. The method of claim 5, wherein the indication is a first indication and the target address is a first target address, the method further comprising:

detecting a second indication of a second target address for the group communication;

adding the second target address to the call message in response to the detecting of the indication; and

removing the second target address from the call message in response to receiving an indication of cancellation of the information.

7. The method of claim 6, wherein the cancellation is indicated by detecting that another target address has been highlighted without selecting the second target address.

8. The method of claim 1, wherein the call message is at least one of a Session Initiation Protocol (SIP) INVITE message or a Q-Chat Signaling Protocol (QSP) call message.

9. The method of claim 1, wherein the PTT group communication is a half-duplex communication.

10. The method of claim 1, wherein detecting the indication of the information comprises:

detecting a selection of a target address from an address book stored in a wireless device.

11. The method of claim 10, wherein the selection of a target address is indicated by highlighting the selection on a display of the wireless device.

12. A software program product comprising a medium for storing the software program in the wireless device, the software program including program code for setting up a push-to-talk (PTT) group communication, wherein the software program upon being executed causes the wireless device to:

detect an indication of information for a PTT call parameter of the group communication;

add the information to a call message in response to the detection of the indication; and

receive, after the information has been added to the call message, a validation of the information.

13. The software program product of claim 12, further causing the wireless device to:

receive an instruction to transmit the call message after the information has been added to the call message; and

transmit the call message.

14. The software program product of claim 13, wherein the instruction to transmit the call message is indicated by detecting that a PTT button on a wireless device has been depressed.

15. The software program product of claim 12, wherein the information is a target address.

16. The software program product of claim 15;

wherein the validation of the information is indicated by detecting an input to select the target address for the group communication.

17. The software program product of claim 16, wherein the indication is a first indication and the target address is a first target address, the software program product further causing the wireless device to:

detect a second indication of a second target address for the group communication;

add the second target address to the call message in response to the detecting of the indication; and

remove the second target address from the call message in response to receiving an indication of cancellation of the information.

18. The software program product of claim 17, wherein the cancellation is indicated by detecting that another target address has been highlighted without selecting the second target address.

19. A wireless device for setting up a push-to-talk (PTT) group communication, the wireless device comprising:

means for detecting an indication of information for a PTT call parameter of the group communication;

means for adding the information to a call message in response to the detecting of the indication; and

means for receiving, after the information has been added to the call message, a validation of the information.

20. A wireless device configured to conduct a push-to-talk (PTT) group communication, the wireless device comprising:

memory configured to store a template for use in constructing a call message;

means for detecting an indication of information for a PTT call parameter of the group communication and adding the information to a call message in response to the detecting of the indication; and

a keyboard configured to receive, after the information has been added to the call message, a validation of the information.

21. The wireless device of claim 20, further comprising:

a display screen configured to display alphanumeric characters.

22. The wireless device of claim 20, further comprising:

a PTT button configured to receive an input to transmit the call message after the information has been added to the call message.

23. The wireless device of claim 22, further comprising:

transmitter circuitry configured to transmit the call message in response to the input to the PTT button.

24. The wireless device of claim 23, wherein the call message is at least one of a Session Initiation Protocol (SIP) INVITE message or a Q-Chat Signaling Protocol (QSP) call message.
