Abstract
A system and method for minimizing call setup latency in a group communication among wireless communication devices by ensuring the requisite amount of communication bandwidth for group member devices that utilize separate communication systems to control communication channels established with each of the wireless communication devices. A group communication server that sets up group communications for wireless communication device members of a communication group communicates with a resource manager resident on a communication system to reserve a predetermined amount of resources, such as bandwidth, for wireless communication devices utilizing that communication system that are members of a communication group. The resource manager communicates the availability to the group communication server of the wireless communication devices utilizing that communication system for group communications only if the predetermined resources are available for a group communication to the wireless communication device.

2. A group communication server comprising one or more processors configured to:
-
receive a request to set up a wireless group communication among multiple wireless communication devices utilizing multiple communication systems to participate in the wireless group communication; send a request to reserve resources that the multiple wireless communication devices require to participate in the wireless group communication to resource managers resident in each of the multiple communication systems prior to establishing the wireless group communication; receive messages from the resource managers in each of the multiple communication systems indicating whether the resources that the wireless communication devices utilizing the respective communication systems require to participate in the wireless group communication were successfully reserved within the respective communication systems; and determine whether to establish the wireless group communication based on whether the messages received from the resource managers in each of the multiple communication systems indicate that the resources that all of the multiple wireless communication devices require to participate in the wireless group communication were successfully reserved. - View Dependent Claims (3, 4, 5, 6, 7, 8, 9)
