Abstract
A method of realizing hard handoff between frequency assignments in a mobile communication system is disclosed. The method is capable of building and managing base stations having different FA while significantly reducing the probability of call drops during hard handoff between FA, such that the call capacity can be increased. The method of realizing hard handoff between different FA includes the steps of setting guard sectors among sectors of a plurality of base stations, allowing a mobile station to transmit a message which requests handoff at a boundary area between the base stations to a base station currently in service, implementing soft handoff between the base stations, and implementing hard handoff between FA after implementing the soft handoff.
