System and method for providing group calling in a wireless network
First Claim
1. A method comprising:
- receiving a request to participate a group call from a mobile device located in a wireless service area;
determining whether a threshold number of other mobile devices in the wireless service area are participating in the group call;
if the threshold number of the other mobile devices are participating in the group call, designating the requesting mobile device to receive a multicast transmission of the group call; and
if the threshold number of other mobile devices are not participating in the group call, designating the requesting mobile device to receive a unicast transmission of the group call.
