Method and apparatus for controlling operation mode of femtocell base station

摘要

A method for controlling an operation mode of a femtocell base station includes receiving a channel quality indicator of a downlink channel between the femtocell base station and a terminal, which is transmitted from the terminal; calculating a communication quality between the femtocell base station and the terminal based on the channel quality indicator; determining whether or not an interference factor has occurred in communication between the femtocell base station and the terminal based on the communication quality; and changing or maintaining an operation mode of the femtocell base station based on the determination result. The communication quality may be calculated when the operation mode of the femtocell base station is allowed to be changed.

1. A method for controlling an operation mode of a femtocell base station, the method comprising:
receiving a channel quality indicator of a downlink channel between the femtocell base station and a terminal, which is transmitted from the terminal; calculating a communication quality between the femtocell base station and the terminal based on the channel quality indicator; determining whether or not an interference factor has occurred in communication between the femtocell base station and the terminal based on the communication quality; and changing or maintaining an operation mode of the femtocell base station based on the determination result, wherein the changing or maintaining the operation mode includes changing the operation mode of the femtocell base station to a mixed user access mode when it is determined that the interference factor has occurred during a closed user access mode of the femtocell base station, wherein the mixed user access mode provides closed subscriber group (CSG) subscribers with a closed type service, and CSG non-subscribers with an open type service to offer differentiated services to each group; and after the changing or maintaining the operation mode:
determining whether or not a service quality required by a subscriber terminal connected to the femtocell base station is met when a non-subscriber terminal is connected to the femtocell base station;changing the operation mode of the femtocell base station to the closed user access mode when it is determined that the service quality is not met;determining whether or not a communication resource assigned to the femtocell base station is allowed to be shared when the non subscriber terminal is connected to the cell base station; andwhen it is determined that the communication resource is not allowed to be shared, allowing the non-subscriber terminal to perform a handover and changing the operation mode of the femtocell base station to the closed user access mode.
