Patent ID: 8817697

Claim:
A system for minimizing call setup latency in a group communication among wireless communication devices, comprising: a plurality of communication systems for wireless communication devices, wherein the plurality of communication systems are each configured to control communications channels established with each of the wireless communication devices utilizing that communication system to participate in a wireless group communication; at least one group communication server configured to set up the wireless group communication for each of the wireless communication devices that are members of a communication group before establishing the wireless group communication among the member wireless communication devices; and a resource manager resident on at least one communication system of the plurality of communication systems, wherein the resource manager is configured to reserve an amount of resources that are required by each of the member wireless communication devices utilizing the at least one communication system to participate in the wireless group communication, and to communicate to the at least one group communication server that each of the member wireless communication devices utilizing the at least one communication system are allowed to participate in the wireless group communication only if the amount of resources required for all of the member wireless communication devices utilizing the at least one communication system to participate in the wireless group communication have been successfully reserved within the at least one communication system, wherein the at least one group communication server is further configured to establish the wireless group communication with the member wireless communication devices utilizing the at least one communication system only if the resource manager confirms that the required amount of resources have been reserved to all member wireless communication devices utilizing the at least one communication system to participate in the wireless group communication.
