Patent ID: 6975605

Claim:
A radio communication system performing a soft hand-off procedure for a mobile station, the radio communication system, comprising: a base station controller for determining a commencement and a termination of the soft hand-off procedure, a first base station for performing asynchronous communication with said base station controller via a first communication line and for assigning a first hand-off exclusive bandwidth to the first communication line bases on the commencement of the soft hand-off procedure, and a second base station for performing asynchronous communication with said base station controller via a second communication line and for assigning a second hand-off exclusive bandwidth, that is approximately equal to the first hand-off exclusive bandwidth, to the second communication line bases on the commencement of the soft hand-off procedure, wherein said the first base station comprising: a soft hand-off bandwidth assign equipment for assigning the first hand-off exclusive bandwidth to the first communication line, a normal bandwidth assign equipment for assigning a normal communication bandwidth to the first communication line, and a bandwidth controller for activating said soft hand-off bandwidth during the soft hand-off procedures based on the commencement and a termination of the soft hand-off procedure, and wherein the second base station comprising: a soft hand-off bandwidth assign equipment for assigning the second hand-off exclusive bandwidth to the second communication line, a normal bandwidth assign equipment for assigning a normal communication bandwidth to the second communication line, and a bandwidth controller for activating said soft hand-off bandwidth during the soft hand-off procedures based on the commencement and a termination of the soft hand-off procedure.
