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.

Abstract: A Radio Data Communications System (20) capable of interfacing with an existing standard communication network (10) of linked controllers (14) and fixed terminal device (16) all operating on a pre-established protocol. The Radio Data Network (20) includes a plurality of portable radio terminals (40) each of which may emulate a fixed terminal display (16) normally operating in the existing computer controlled network. There are intended to be more portable radio terminals (40) than there are LU sessions with each of such portable radio terminals (40) being associated with a particular, defined hunt group comprised of a plurality of certain of the available LU sessions and to which the portable radio terminals (40) effectively might contend for.
