Abstract

In one embodiment, a method includes initiating a dynamic group call, detecting a call alert, and identifying a user system responsible for the call alert. The dynamic group call includes at least one original participant, and is initiated such that an ability to automatically add at least one new participant to the dynamic group call is enabled. Identifying the user system includes obtaining an indicator from the call alert. The indicator is associated with the user system. Finally, the method includes automatically adding the user system to the dynamic group call.

Claims

1. A method comprising:

initiating a dynamic group call, the dynamic group call including at least one original participant, wherein the dynamic group call is initiated to enable automatically adding at least one new participant to the dynamic group call;

detecting a call alert;

identifying a user system responsible for the call alert, wherein identifying the user system includes obtaining an indicator from the call alert, the indicator being associated with the user system; and

automatically adding the user system to the dynamic group call.

2. The method of claim 1 further including:

advertising access information, the access information being arranged to allow the user system to provide the call alert.

3. The method of claim 1 wherein the indicator is a direct connect number, the direct connect number being associated with the user system.

4. The method of claim 3 wherein automatically adding the user to the dynamic group call includes automatically adding the direct connect number to the dynamic group call.

5. The method of claim 1 wherein the user system includes a radio communication device.

6. The method of claim 1 further including:

authenticating the user system before automatically adding the user system to the dynamic group call.

7. The method of claim 6 wherein authenticating the user system includes determining if the user system is identified as being blocked from joining the dynamic group call.

8. The method of claim 1 further including:

obtaining a notification to initiate the dynamic group call before initiating the dynamic group call.

9. The method of claim 8 wherein the notification is obtained from an Internet Protocol Interoperability and Collaboration System (IPICS) server, and the notification includes a managed list, the managed list being arranged to identify the at least one participant.

24. The method of claim 1 wherein detecting the call alert includes detecting the call alert while the dynamic group call is in progress, and wherein automatically adding the user system to the dynamic group call includes automatically adding the user system to the dynamic group call while the dynamic group call is in progress.

10. A non-transitory computer-readable medium comprising computer program code, the computer program code, when executed, configured to:

initiate a dynamic group call, the dynamic group call including at least one original participant, wherein the dynamic group call is initiated to enable automatically adding at least one new participant to the dynamic group call;

detect a call alert;

identify a user system responsible for the call alert, wherein the computer program code configured to identify the user system includes computer program code configured to obtain an indicator from the call alert, the indicator being associated with the user system; and

automatically add the user system to the dynamic group call.

11. The non-transitory computer-readable medium of claim 10 further including computer program code configured to:

advertise access information, the access information being arranged to allow the user system to provide the call alert.

12. The non-transitory computer-readable medium of claim 10 wherein the indicator is a direct connect number, the direct connect number being associated with the user system.

13. The non-transitory computer-readable medium of claim 12 wherein the computer program code configured to automatically add the user to the dynamic group call includes computer program code configured to automatically add the direct connect number to the dynamic group call during the dynamic group call, and wherein the computer program code configured to automatically add the direct connect number to the dynamic group call is configured to cause the user system to participate in the dynamic group call.

14. The non-transitory computer-readable medium of claim 10 wherein the user system includes a radio communication device.

15. The non-transitory computer-readable medium of claim 10 further including computer program code configured to:

authenticate the user system before automatically adding the user system to the dynamic group call.

16. The non-transitory computer-readable medium of claim 15 wherein the computer program code configured to authenticate the user system includes computer code configured to determine if the user system is identified as being blocked from joining the dynamic group call.

17. The non-transitory computer-readable medium of claim 10 further including computer code configured to:

receive a notification to initiate the dynamic group call before initiating the dynamic group call.

18. The non-transitory computer-readable medium of claim 17 wherein the notification is received from an Internet Protocol Interoperability and Collaboration System (IPICS) server, and the notification includes a managed list, the managed list being arranged to identify the at least one participant.

19. An apparatus comprising:

means for initiating a dynamic group call, the dynamic group call including at least one original participant, wherein the dynamic group call is initiated to enable automatically adding at least one new participant to the dynamic group call;

means for detecting a call alert;

means for identifying a user system responsible for the call alert, wherein the means for identifying the user system include means for obtaining an indicator from the call alert, the indicator being associated with the user system; and

means for automatically adding the user system to the dynamic group call.

20. An apparatus comprising:

dynamic group call logic, the dynamic group call logic being arranged to initiate a dynamic group call including at least one original participant, the dynamic group call logic further being arranged to allow at least one new participant to be automatically added to the dynamic group call after the dynamic group call is initiated;

call alert logic, the call alert logic being arranged to detect a call alert from a user system, the call alert being arranged to indicate that the user system is requesting access to the dynamic group call, wherein the dynamic group call logic is still further arranged to automatically add the user system to the dynamic group call as the at least one new participant after the call alert from the user system is detected; and

a processing arrangement, the processing arrangement being arranged to execute the logic.

21. The apparatus of claim 20 wherein the apparatus is a radio control service server of an Internet Protocol Interoperability and Collaboration System (IPICS) system.

22. The apparatus of claim 20 wherein the dynamic group call logic is further arranged to authenticate the user system before the user system is added to the dynamic group call.

23. The apparatus of claim 20 wherein the dynamic group call logic is further arranged to identify a direct connect number in the call alert, the direct connect number being associated with the user system, and wherein the dynamic group call logic arranged to automatically add the user system to the dynamic group call is arranged to add the direct connect number to the dynamic group call.
