ABSTRACT:
An exemplary embodiment of the present invention provides a method for establishing a communication path between a first mobile station and a second mobile station both positioned within an operating region of a base station in a cordless communication system. According to the embodiment, subbands are first checked to determine whether an available subband within an auxiliary communication band exists. When an available subband exists, a synchronization packet is transmitted from the first mobile station to the second mobile station using an initial synchronization frequency. In response to receipt of the synchronization packet by the second mobile station, a synchronization identification packet is transmitted from the second mobile station to the first mobile station. The synchronization identification packet is received at the first mobile station, and then a signalling process between the second mobile station and the first mobile station is performed using a leaping pattern indicated by the synchronization packet, to thereby establish the communication path.
