Abstract
Systems, methods, and apparatuses (including, but not limited to, User Equipment (UE) and servers) that provide Push to Talk (PTT) over Cellular (PoC) service are described. Whether a PoC group call is established and/or released depends on the priority of any currently connected PoC groups and the number of current PoC connections.

17. A method for a User Equipment (UE) which provides a Push to talk over Cellular (PoC) service, comprising:
-
transmitting, to a server, a PoC group call request for a PoC connection for a PoC group; and receiving a PoC group call response from the server in response to the PoC group call request, the PoC group call response comprising one of a rejection response and an acceptance response, based on a priority of any currently connected PoC groups and a number of current PoC connections. - View Dependent Claims (18, 19, 20)
