Abstract

A method and apparatus for avoiding simultaneous service origination and paging in a mobile operating in a group communication network provides for receiving a floor-control request, e.g., in short data burst (SDB) form, from a source communication device for initiating a group call, initiating a service origination process for the source communication device, and transmitting a response to the floor-control request from a controller after the service origination process is complete. In one aspect, the method and apparatus provides for transmitting a response to the floor-control request from a wireless infrastructure after the service origination process is complete. In another aspect, the method and apparatus provides for initiating the service origination process for the source communication device after transmitting the response to the source communication device.

Claims

1. A method for avoiding simultaneous service origination and paging in a mobile operating in a group communication network, the method comprising:

receiving a floor-control request from a source communication device for initiating a group call;

initiating a service origination process from the source communication device;

transmitting a response to the floor-control request; and

delaying a response to the floor control request at a communications manager to avoid paging, wherein the paging is initiated at an infrastructure to re-establish a traffic channel with the source communications device.

2. The method of claim 1, further including caching the floor-control response before the transmitting.

3. The method of claim 1, wherein the receiving includes receiving the floor-control request on a reverse common channel.

4. The method of claim 3, wherein the receiving includes receiving the floor-control request on a reverse access channel.

5. The method of claim 3, wherein the receiving includes receiving the floor-control request on a reverse enhanced access channel.

6. The method of claim 3, wherein receiving the floor-control request is in short data burst form.

7. The method of claim 1, further including transmitting a response after the service origination process is complete.

8. An apparatus for avoiding simultaneous service origination and paging in a mobile operating in a group communication network, comprising:

means for receiving a floor-control request from a source communication device for initiating a group call;

means for initiating a service origination process from the source communication device;

means for transmitting a response to the floor-control request; and

means for delaying a response to the floor control request at a communications manager to avoid paging, wherein the paging is initiated at an infrastructure to re-establish a traffic channel with the source communications device.

9. The apparatus of claim 8, further including means for caching the floor-control response before the transmitting.

10. The apparatus of claim 8, wherein the means for receiving includes means for receiving the floor-control request on a reverse common channel.

11. The apparatus of claim 10, wherein the means for receiving includes means for receiving the floor-control request on a reverse access channel.

12. The apparatus of claim 10, wherein the means for receiving includes means for receiving the floor-control request on a reverse enhanced access channel.

13. The apparatus of claim 10, wherein the means for receiving includes means for receiving the floor-control request in short data burst form.

14. The apparatus of claim 8, further including means for transmitting a response after the service origination process is complete.

18. The apparatus of claim 12, wherein the receiver is further capable to receive the floor-control request on a reverse access channel.

15. An apparatus for avoiding simultaneous service origination and paging in a mobile operating in a group communication network, comprising:

a receiver capable to receive a floor-control request for initiating a group call and a service origination process from a source communication device;

a transmitter capable to transmit a response to the floor-control request; and

a processor communicatively coupled to the receiver and the transmitter, the processor being capable to avoid simultaneous service origination and paging in a group communication network, wherein the processor is configured to not respond immediately to the floor-control request.

16. The apparatus of claim 15, the processor further being capable of to cache the floor-control response before the transmitting.

17. The apparatus of claim 15, wherein the receiver is further capable to receive the floor-control request on a reverse common channel.

19. The apparatus of claim 17, wherein the receiver is further capable to receive the floor-control request on a reverse enhanced access channel.

20. The apparatus of claim 17, wherein the receiver is further capable to receive the floor-control request in short data burst form.

21. The apparatus of claim 15, wherein the transmitter is further capable to transmit a response to the floor-control request after the service origination process is complete.

22. A method for avoiding simultaneous service origination and paging in a mobile operating in a group communication network, the method comprising:

receiving a floor-control request from a source communication device for initiating a group call;

initiating a service origination process from the source communication device;

transmitting a response to the floor-control request;

delaying a response to the floor control request at a communications manager to avoid paging, wherein the paging is initiated at an infrastructure to re-establish a traffic channel with the source communications device; and

not issuing a service origination request until after a talker mobile station has received a response to the floor-control request.

23. The method of claim 22, further including transmitting a response after the service origination process is complete.

24. The method of claim 22, further including caching the floor-control response before the transmitting.

25. The method of claim 22, wherein the receiving includes receiving the floor-control request on a reverse common channel.

26. The method of claim 25, wherein the floor-control request is on a reverse access channel.

27. The method of claim 25, wherein the floor-control request is on a reverse enhanced access channel.

28. The method of claim 22, further including receiving a floor-control request and a service origination request bundled in an access channel capsule from the source communication device in the group communication network.

29. The method of claim 28, wherein the bundle has application data with CDMA signaling data.

30. The method of claim 28, wherein the bundle is in short data burst form.
