CLAIMS

1. A method, comprising:

receiving, at a first Push to Talk (PTT) server, a request to merge a first active group call and a second active group call, wherein a first group of PTT clients participate in the first active group call and a second group of PTT clients participate in the second active group call;

sending, from the first PTT server and to a first group PTT server, a first invite message, wherein the first group PTT server hosts the first active group call;

receiving, in response to the first invite message, a first response message; sending, from the first PTT server and to a second group PTT server, a second invite message, wherein the second group PTT server hosts the second active group call;

receiving, in response to the second invite message, a second response message; and

hosting a merged PTT group call, wherein the first group of PTT clients and the second group of PTT clients participate in the merged PTT group call.

2. The method of claim 1, further comprising:

receiving a moderator media burst request from the first group PTT server, wherein the moderator media burst request indicates a pending request to send media, wherein the pending request is received at the first group PTT server prior to the receiving of the request to merge the first and the second active group calls; and

sending a moderator media burst grant message, wherein the moderator media burst grant message grants the pending request.

3. The method of claim 2, wherein the moderator media burst request indicates a Multimedia Broadcast/Multicast Service (MBMS) bearer that is used by at least one PTT client of the first group of PTT clients for the first active group call.

4. The method of claim 2, wherein the moderator media burst request indicates at least one of a timestamp, a queue position, or a priority of the pending request.

5. The method of claim 1, further comprising:

sending a first subscribe request to the first group PTT server;

receiving, in response to the first subscribe request, a first notify message, wherein the first notify message identifies the first group of PTT clients;

sending a second subscribe request to the second group PTT server; and receiving, in response to the second subscribe request, a second notify message, wherein the second notify message identifies the second group of PTT clients.

6. The method of claim 1, further comprising:

receiving a subscribe request from the first group PTT server; and

sending, in response to the subscribe request, a first notify message, wherein the first notify message identifies the second group of PTT clients.

7. The method of claim 6, further comprising:

sending a second notify message, wherein the second notify message identifies a PTT client that joins or leaves the merged group call.

8. A device, comprising:

a memory; and

at least one hardware processor communicatively coupled with the memory and configured to:

receive, at a first Push to Talk (PTT) server, a request to merge a first active group call and a second active group call, wherein a first group of PTT clients participate in the first active group call and a second group of PTT clients participate in the second active group call;

send, from the first PTT server and to a first group PTT server, a first invite message, wherein the first group PTT server hosts the first active group call;

receive, in response to the first invite message, a first response message; send, from the first PTT server and to a second group PTT server, a second invite message, wherein the second group PTT server hosts the second active group call;

receive, in response to the second invite message, a second response message; and

host a merged PTT group call, wherein the first group of PTT clients and the second group of PTT clients participate in the merged PTT group call.

9. The device of claim 8, wherein the at least one hardware processor is further configured to:

receive a moderator media burst request from the first group PTT server, wherein the moderator media burst request indicates a pending request to send media, wherein the pending request is received at the first group PTT server prior to the receiving of the request to merge the first and the second active group calls; and send a moderator media burst grant message, wherein the moderator media burst grant message grants the pending request.

10. The device of claim 9, wherein the moderator media burst request indicates a Multimedia Broadcast/Multicast Service (MBMS) bearer that is used by at least one PTT client of the first group of PTT clients for the first active group call.

11. The device of claim 9, wherein the moderator media burst request indicates at least one of a timestamp, a queue position, or a priority of the pending request.

12. The device of claim 8, wherein the at least one hardware processor is further configured to:

send a first subscribe request to the first group PTT server;

receive, in response to the first subscribe request, a first notify message, wherein the first notify message identifies the first group of PTT clients;

send a second subscribe request to the second group PTT server; and receive, in response to the second subscribe request, a second notify message, wherein the second notify message identifies the second group of PTT clients.

13. The device of claim 8, wherein the at least one hardware processor is further configured to:

receive a subscribe request from the first group PTT server; and

send, in response to the subscribe request, a first notify message, wherein the first notify message identifies the second group of PTT clients.

14. The device of claim 13, wherein the at least one hardware processor is further configured to:

send a second notify message, wherein the second notify message identifies a PTT client that joins or leaves the merged group call.

15. A tangible, non-transitory computer-readable medium containing instructions which, when executed, cause a computing device to perform operations comprising:

receiving, at a first Push to Talk (PTT) server, a request to merge a first active group call and a second active group call, wherein a first group of PTT clients participate in the first active group call and a second group of PTT clients participate in the second active group call;

sending, from the first PTT server and to a first group PTT server, a first invite message, wherein the first group PTT server hosts the first active group call;

receiving, in response to the first invite message, a first response message; sending, from the first PTT server and to a second group PTT server, a second invite message, wherein the second group PTT server hosts the second active group call;

receiving, in response to the second invite message, a second response message; and

hosting a merged PTT group call, wherein the first group of PTT clients and the second group of PTT clients participate in the merged PTT group call.

16. The tangible, non-transitory computer-readable medium of claim 15, wherein the operations further comprise:

receiving a moderator media burst request from the first group PTT server, wherein the moderator media burst request indicates a pending request to send media, wherein the pending request is received at the first group PTT server prior to the receiving of the request to merge the first and the second active group calls; and sending a moderator media burst grant message, wherein the moderator media burst grant message grants the pending request.

17. The tangible, non-transitory computer-readable medium of claim 16, wherein the moderator media burst request indicates a Multimedia Broadcast/Multicast Service (MBMS) bearer that is used by at least one PTT client of the first group of PTT clients for the first active group call.

18. The tangible, non-transitory computer-readable medium of claim 15, wherein the operations further comprise:

sending a first subscribe request to the first group PTT server;

receiving, in response to the first subscribe request, a first notify message, wherein the first notify message identifies the first group of PTT clients;

sending a second subscribe request to the second group PTT server; and receiving, in response to the second subscribe request, a second notify message, wherein the second notify message identifies the second group of PTT clients.

19. The tangible, non-transitory computer-readable medium of claim 15, wherein the operations further comprise:

receiving a subscribe request from the first group PTT server; and

sending, in response to the subscribe request, a first notify message, wherein the first notify message identifies the second group of PTT clients.

20. The tangible, non-transitory computer-readable medium of claim 19, wherein the operations further comprise:

sending a second notify message, wherein the second notify message identifies a PTT client that joins or leaves the merged group call.
