Patent ID: 8219098

Claim:
A femtocell base station applicable to automatically perform a switching process with other femtocell base stations within a communication coverage under a circumstance that a mobile communication apparatus accesses the femtocell base station, the femtocell base station comprising: a database for storing an authorization list authorizing the mobile communication apparatus to access the other femtocell base stations within the communication coverage; a setting module for setting up a communication warning value and a signal capturing duration; a detecting module for detecting a signal intensity of the femtocell base station and performing a timing process according to a setting range of the signal capturing duration when the signal intensity is less than the communication warning value; a capturing module for continuously capturing the signal intensity of the femtocell base station and the signal intensity of the other femtocell base stations in the authorization list and establishing a priority list according to magnitudes of the signal intensities after the timing process finishes; and a switching module for comparing the signal intensities in the priority list and selecting one from the other femtocell base stations which has the highest priority in the priority list as an object for performing a switching process when the signal intensity of the femtocell base station is less than the signal intensities of the other femtocell base stations in the authorization list.
