Patent ID: 7940725

Claim:
A method of performing a handover between one cell of a serving base station and another cell of a neighboring base station of a mobile station, comprising: scanning signals transmitted from the serving base station and the neighboring base station at a periodic interval; measuring a power of the transmitted signals from the serving base station and the neighboring base station; comparing the measured power of the transmitted signal from the serving base station to a critical power; forming a movement discriminator based on the measured power of the transmitted signals when the comparing determines that the measured power of the transmitted signal from the serving base station is below the critical power; accumulatively registering the movement discriminator; determining whether to perform the handover or whether not to perform the handover based on a plurality of the registered movement discriminators, wherein the plurality of the movement discriminators includes a first movement discriminator denoting that the mobile station stays in the cell of the serving base station and a second movement discriminator denoting that the mobile station stays in the cell of the neighboring base station, wherein the determining includes determining to perform the handover when a total number of the second movement discriminators consecutively registered is greater than a reference number; and repeating the scanning, the measuring, the comparing, the forming, the registering and the determining when the handover is determined not to be performed based on the registered movement discriminators.
