ABSTRACT:
Remote units within a first communication system (121) utilizes frequencies (channels) from a second communication system (120) when placing a call. When a first remote unit (106) wants to call a second remote unit (107) using the channels, the first remote unit sends a base station (103) a list of top N traffic channel blocks from the second communication system along with the identity of the second remote unit. The base station then pages the second remote unit using a signaling channel reserved by second system. The second remote unit responds to the page with its list of best traffic channel blocks/chunks. The base station then picks the best overlap of idle channels from the list received by the remote units, and sends the list to the remote units instructing them use those traffic channels. Once the remote units receive the available channels, they can begin their call.
