A method of providing a communication link in a radio communication system (100) that supports a number of communication cells. Each cell provides communication from respective serving communication units (112-132) to a number of remote communication units (112-116) operating in a respective cell. The method includes the steps of assigning (308) dynamically a location specific group identification code to a group of communication units based upon said communication units' location or cell within the radio communication system; and providing group communication to said group of remote communication units only within said remote communication units' location or cell. This provides the advantage that there is no requirement to re-program communication units with specific call areas, as call area definition is centrally controlled. In addition, the method supports selective calling within dynamically defined call areas. <IMAGE>
