Abstract
A system and method for managing radio frequency interference of a low power base station is disclosed. The method comprises determining that the low power base station is causing substantial interference in a data link between a mobile station and a macro base station. The low power base station is identified as having a closed subscriber group (CSG) that is in CSG-Closed mode. The CSG low power base station is converted from CSG-Closed mode to a CSG-Open mode to allow the mobile station to communicate through the CSG low power base station.

A method for managing radio frequency interference of a low power base station, comprising:
- determining that the low power base station is causing substantial interference in a data link between a mobile station and a macro base station;
- identifying that the low power base station is a closed subscriber group (CSG) low power base station operating in a CSG-Closed mode;
- sending a connection request from the mobile station to a self optimizing network (SON) server through the CSG low power base station, when the mobile station is not a member of the CSG, indicating that the substantial interference is occurring;
- and
- converting the CSG low power base station from the CSG-Closed mode to a CSG-Open mode to allow the mobile station to communicate through the CSG low power base station.
A system for managing radio frequency interference of a low power base station, comprising:
- an interference detection module configured to measure radio frequency interference in a wireless link between at least one mobile station and a macro base station that is caused by a low power base station having a closed subscriber group (CSG), wherein the macro base station and the low power base station have a same frequency assignment and the mobile station is not a member of the CSG;
- and
- an interference communication module in communication with a self optimizing network (SON) server that is configured to convert a CSG low power base station to an open mode when the interference detection module indicates that the radio frequency interference in the wireless link is greater than a selected threshold to enable the at least one mobile station to communicate through the CSG low power base station.
