1. A method for adjusting coverage in a wireless communication system, comprising the steps of:
- providing a plurality of cells, including a first serving cell and a second serving cell;
providing a first plurality of wireless devices and a second plurality of wireless devices, wherein the first plurality of wireless devices monitor a signal strength of the first serving cell and the second plurality of wireless devices monitor a signal strength of the second serving cell;
collecting signal strength information from the first plurality of wireless devices at the first serving cell;
collecting signal strength information from the second plurality of wireless devices at the second serving cell;
determining coverage area of the first and second serving cells based on the respective collected signal strength information;
exchanging coverage area information between the first serving cell and the second serving cell; and
adjusting the coverage area of the first or the second serving cell based on the determined coverage area information of the first and second serving cells.

Abstract
Methods and systems are provided for adjusting sectors across coverage cells using base stations interconnected by a packet network. A plurality of wireless devices monitor the pilot channel signal strength of their respective serving cell. The serving cells then collect measurements from the wireless devices and calculate the boundaries of their respective coverage areas. The serving cells then transmit their calculations to their neighboringing cells. Upon receipt, the neighboring cells use the calculations to adjust the coverage of their sectors.
