A method to implement multiple talk-around communication links using the communication resources of one repeater. A system resource controller (13) determines whether talk-around is possible for any two communication units (11) intending to engage in a point-to-point communication link. Assignment of a talk-around repeater (15) depends on the geographic locations of the two communication units, and a predetermined range criterion between them. In addition, the talk-around communication must not interfere with any existing talk-around communication already in the system. When talk-around communication is possible, an enabling communication grant is issued to the units, and the talk-around repeater's communication resources are assigned to support the link. Otherwise, a repeater (16) for normal trunking is assigned.
