Abstract

A radio communication system (200) employs a method (400) and system (200) for establishing a communication between communication units (212-217) using geographically distributed packet duplicators (203-205). The communication system (200) includes a system controller (201), a plurality of packet duplicators (203-205), a plurality of base sites (207-210), and a plurality of communication units (212-217). The packet duplicators (203-205), which provide interconnectivity between the base sites (207-210), are distributed throughout geographic regions (233-234) of the system (200). When the system controller (201) receives a request to communicate from one communication unit (e.g., 212) in a group of communication units (e.g., 212-215), the system controller (201) selects a packet duplicator (e.g., 203) serving a geographic region (e.g., 233) containing at least one communication unit in the group and uses the selected packet duplicator (203) to establish the group communication.
