Load balancing for capacity improvement in mobile wireless communication networks

A non-transitory computer storage medium having computer-executable instructions stored thereon that, when executed by a computer system, cause the computer system to:

• collect performance parameters from a mobile wireless communications network, the performance parameters being collected for a cell in the mobile wireless communications network and at least one neighboring cell comprising a further cell of the mobile wireless communications network that is adjacent to the cell;
• determine, based upon the collected performance parameters, that load balancing is to be performed for the cell and the neighboring cell;
• adjust a cell geometry for the neighboring cell adjusting a size of the neighboring cell, an antenna tilt of an antenna associated with the neighboring cell, and a pilot power associated with the neighboring cell;
• adjust a further cell geometry for the cell by adjusting a size of the cell, an antenna tilt of an antenna associated with the cell, and a pilot power associated with the cell;
• and
• adjust a handover parameter of the neighboring cell and a handover parameter of the cell to balance a load between the cell and the neighboring cell by reallocating traffic from the cell to the neighboring cell.

A load balancing system comprising:

• a load balancing controller;
• one or more interfaces between the load balancing controller and a mobile wireless communications network;
• a processing unit associated with the load balancing controller;
• and
• a storage device storing one or more modules for execution on the processing unit which, when executed by the processing unit, cause the processing unit to collect performance parameters from the mobile wireless communications network, the performance parameters being collected for a cell in the mobile wireless communications network, to determine, based upon the collected performance parameters, that load balancing is to be performed for the cell, identify a neighboring cell comprising a further cell of the mobile wireless communications network that is adjacent to the cell, adjust a cell geometry for the neighboring cell in the mobile wireless communications network by adjusting one or more of a size of the neighboring cell, an antenna tilt of an antenna associated with the neighboring cell, or a pilot power associated with the neighboring cell, and adjust a handover parameter of the neighboring cell and a handover parameter of the cell to balance a load between the cell and the neighboring cell by reallocating traffic from the cell to the neighboring cell.
