Abstract
In the CDMA environment, a local call is directly made between two mobile stations (MS) without the involvement of a base station. The local direct calls do not interfere with any existing communication lines, and the implementation on the CDMA based units includes Master MS units and Slave MS units which selects one of currently unused offset values in a pilot signal for a local direct call in the CDMA environment.
