Method for controlling interference in femto cell deployments

摘要

A method and system provide a plurality of femto cells that are deployed within a macro cell of cellular network. The femto cells improve cellular service inside structures, such as residential and commercial structures. Femto base stations convert signals between an airlink-interface and core network to enable data communication between the mobile terminal and an access network to occur through the Internet and a public switched telephone network. The femto base stations are independent of each other and the macro cell. The method and system provide the femto base stations with interference awareness and mitigation techniques to minimize interference with the cellular network.

1. One or more computer-readable storage memories embodying processor-executable instructions which, responsive to execution by at least one processor, are configured to:
identify, using a femto cell in a wireless communication network, a plurality of preselected wireless signal carriers based on a predefined geographical area; measure, using the femto cell, initial power levels for the wireless signal carriers provided in the predefined geographical area; select, using the femto cell, one of the wireless signal carriers based on predefined criteria associated with the measured initial power level; and adjust, using the femto cell, a transmission power level of a femto transmitter associated with the femto cell based on a communication placed to a mobile terminal.
