ABSTRACT:
A radio communication system (100) includes equipment (112) that manages communication initiated at a subscriber unit (122) and targeted at another subscriber unit (124). At the initiating subscriber unit, a communication mode is selected (410) from among multiple communication modes supported by the target subscriber unit. A mode independent identifier is obtained (420) for the target subscriber unit, and transmitted (430) to the system equipment along with the selected communication mode. The system equipment uses information based on the mode independent identifier to access (510, 520) the target subscriber unit. The system equipment then operates to enable (530, 540) the communication mode at the target subscriber unit, and to establish (550) communication between the initiating and target subscriber units.
